大学英语四级阅读真题原文Passage OneQuestions 56 to 60 are based on the following passage.Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.The world is facing an astonishing rise in the number of old people. And they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates are falling among younger unskilled people, whereas older skilledfolk are working longer. The divide is most extreme in America, where well-educated baby-boomers (二战后生育高峰期出生的美国人) are putting off retirement while many less-skilled younger people have dropped out of the workforce.Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy(预期寿命), combined with the replacement of generous defined-benefit pension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than the preceding generation. Technological change may well reinforce that shift: the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.大学英语四级阅读题目注意：此部分试题请在答题卡2上作答。

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbcIn the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcbThere are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbccAs she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on yourtoes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith didnot hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：dbdcdIf the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd。

大学英语四级阅读理解试题及答案（四）十六Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size.The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this providesan easy entry for disease, but itis awound that will heal. Often there is a race between the healing and the desease asto whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.1.Pruning should be done to ______.a.make the tree grow tallerb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______. a.allows too many branches to grow in the middleb.does not protect them from windc.forces them to grow too quicklyd.damages some of the small side branches3.Why is a special substance painted on the tree? a.To make a wound smoothb.To prevent disease entering a woundc.To cover a rough surfaced.To help a wound to dry4.A good gardener prunes a tree______.a.at intervals throughout the yearb.as quickly as possiblec.occasionally when necessaryd.regular every winter5.What was the author's purpose when writing this passage? a.To give pratical instruction for pruning a tree.b.To give a general description of pruningc.To explain how trees develop diseasesd.To discuss different methods of pruning.答案： babca十七On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag withher money and her key in it, pulled the door behind her to lock it and went to the over60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign offorced entry.Over a cup of tea she wondered whether someone might have a key that fittedher front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that shewent out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four o'clock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs. Clarke raised the kettle andpoured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.1.Mrs. Clarke looded forward to Thursday because_______. a.she worked at a club on the dayb.she said visitors on Thursdaysc.she visited a club on Thursdayd.a special visitor came on Thursday2.If someone had made a forced entery,_______.a.Mrs.Clarke would have found a broken door or windowb.he or she was still in the housec.things would have been thown aboutd.he or she would have needed a master key3.On the third Thursday Mrs. Clarke went out_______. a.because she didn't want to miss the club again b.to see if the thief was hnging about outsidec.to the club but then changed her mindd.in an attempt to trick the thief4.The lock on the front door was one which_______. a.needed a piece of wire to open itb.could he opened from inside without a keyc.could't be opened without a keyed a knob instead of a key5.The wire feel to the floor_______.a.because Mrs.Clarke refused to open the doorb.when the man's glove dropped offc.because it was too hot to holdd.because the man justwanted to get away答案： cadbd十八Many people believe the glare from snow causessnowblindnenss. Yet, dark glasses or not , they find themselves sufferingfrom headaches and watering eyes,and evensnowblindness,when exposed to several hours of "snow light" . The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man's eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing,hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even though temporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape,Even the scouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see something.Their gaze is arrested. Their eyes focus on a bush and having found something to see,stop scouring thesnow-blanketed lanscape. By focusing their attention on one object at a time,themen can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is overcome.1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are_____.a.indispensibleefulc.ineffectived.available2.When the eyes are sore tears are produced to ________. a.clear the visionb.remedy snowblindnessc.ease the irritationd.loosen the muscles3.Snowblindness may be avoided by_______.a.concentrating to the solid white terrainb.searching for something to look at in snow-covered terrainc.providing the eyes with something to foucs ond.covering the eyeballs with fluid4.The scouts shake snow from evergreen bushes in order to _______.a.bive the men behind something to seeb.beautify the landscapec.warm themselves in the coldd.prevent the men behind from losing their way5.A suitable title for this passage would be _______. a.snowblindness and how to overcome itb.natrue's cure for snowblindnessc.soldiers in the snowd.snow vision答案： CCCAA十九Water problems in the future will become nore intense and more complex. Our increasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complexchemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population,agriculture will have to be intensified. This will involve ever-increasingquantitiesof agricultural chemicals, From this , it is apparent that drastic steps must betaken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involvesthe processing of solid wastes "prior to " disposal and the treatment of liquid wastes, or efflunets,to permit the reuse of the water or minimize pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Efflunets from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential eonomic uses for waste products.1.The purpose of this passage is ______.a.to alert the reader to the dwindling water supplyb.to explain industrial usesof waterc.to acquaint the reader with water pollution problemsd.to demostratevarious measures to solve the pollution problem2.Which of the following points is NOT INCLUDED in the passage?a.In dustrial development incudes the simplification of complex chemical processes.b.Diluting wastes needs certain amount of waterc.Demands for water will go up along with the expanding populationd.Intensive cultivation of land requires more and more chemicals3.The reader can conclued that________.a.countries of the world will work together on polution problemsb.byproducts from wastes lead to a more prosperous marketplacec.science is making great progress on increasing water suppliesd.some industries are now ,aking economic use of wastes4.The author gives substance to the passage through the use of _______.a.interviews with authorities in the field of water controlsb.opinions and personal observationsc.definitions which clarify important termsd.strong arguments and persuasions5.The words "prior to "(para.2 probably mean______. a.afterb.duringc.befored.beyond答案 :cadbc二十One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong , and you were right about that."I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and Ibegan to remember vaguely the incident he was describing.I was about eight years old at the time, and I had gome into the store withmay mother to do the weekly grocery shopping.On that particular day, I must have found my way to the dairy fooddepartment where the incident tood place.There must have been a special sale on eggs that day because there was an impressive display of eggs indozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks.Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I want to work. The manager heard the moise and came rushing over to see what had happened. When he appeared, I was on my kneesinspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit. He severely reprimanded me and wanted me to payfor any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.1.How old was the author when he wrote this article? a.about 8b.about 18c.about 23d.about 15 2.Who was to blame for knocking off the stacks of cartons? a.The author b.The manager c.A woman d.The author's mother 3.Which of the following statements is not true? a.The woman who knocked off the stacks of cartons was seriously criticized by the mananger b.The author was severely critizized by the manager.c.A woman carelessly knocked off the stacks of cartonsd.It was the author who put the display back together 4.Which of the following can serve as the best title for the passage?a.Its Harder to Admit One's Mistakeb.I was once the culpritc.I remember an incidentd.A case of mistaken identity5.The tone of the article expresses the author's_______. a.admiration for the manager'swillingness to admit mistakes b.anger to the manager for his wrong accusationc.indignation against the woman who knocked off the stacks of cartonsd.reget forthe mistake the made in the store答案： ccada。

大学英语四级阅读理解试题及答案（一）There are three kinds of goals: short-term,medium-range and long-term goals.Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.1.Our long-term goals mean a lot__.a.if we complete our short-range goalsb.if we cannot reach solid short-term goalsc.if we write down the datesd.if we put forward some plans2.New short-term goals are bulid upon__.a.two yearsb.long-term goalsc.current activitiesd.the goals that have been completed3.When we complete each step of our goals ,__.a.we will win final successb.we are overwhelmedc.we should build up confidence of successd.we should strong desire for setting new goals4.Once our goals are drawn up,__.a.we should stick to them until we complete themb.we may change our goals as we have new ideas and opportunitiesc.we had better wait for the exciting news of successd.we have made great decision5.It is implied but not stated in the passage that ___.a.those who habe long-term goals will succeedb.writing down the dates may discourage youc.the goal is only a guide for us to reach our desinationd.every should have a goal答案：adcbc二The economy of the United states after 1952 was the econnomy of a well-fed,almost fully employed people. Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University."

During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbd六As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbc七In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing."A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcb八There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc九As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：dbdcd十If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd阅读理解限时训练与解析A（5minutes）I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed（解散）. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized（强调）the fact that when people do something dishonest, they are really cheating（欺骗）themselves. She made me promise that I would think seriously（认真地）about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued（继续）to believe that I had cheated on the test.1. The story took place（发生）exactly ____ .A. in the teacher’s officeB. in an exam roomC. in the schoolD. in the language lab2. The girl wanted to borrow a pen, because ____ .A. she had not brought a pen with herB. she had lost her own on her way to schoolC. there was something wrong with her ownD. her own had been taken away by someone3. The teacher saw all this, so she asked the boy ____ .A. to go on writing his paperB. to stop whisperingC. to leave the room immediatelyD. to stay behind after the exam4. The thing(s) emphasized in her talk was(were) ____ .A. honestyB. sense of dutyC. seriousnessD. all of the above5. The boy knew everything ____ .A. the moment he was asked to stay behindB. when the teacher started talking about honestyC. only some time laterD. when he was walking out of the roomB（7minutes）Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor （酒精饮料）by using fake identification (伪造证件).Parents may start to notice a change in their child’s behavior if the child starts drinking. Kids who drink sometimes stop doing things they normally liked to do. They may keep telephone calls and meetings a secret and not want anybody to touch their things. They act moody (喜怒无常) and do not have the same eating and sleeping habits.Parents need to stay involved (牵涉) in their kids’lives. They should talk to their children about their problems to be aware of any changes.Parents can be the best protection. Children who get a lot of love can feel good about themselves. It helps them resist（抵抗）doing bad things even when other kids are doing them. Parents can also help set a good example by not drinking and driving. They can have firm rules in the home that everyone follows.Give the children good ideas on how to say “no”to drinking, even when they are at a party. Try not to overreact or panic (惊慌) if the child tries alcohol. How you handle it can affect their attitude. It may be helpful to talk to other parents about setting up curfews (宵禁令) and rules about parties or other events.1. Which of the following is NOT the reason why some kids have an early start of drinking?A. They want to show their maturity (成熟) by drinking alcohol.B. Drinking alcohol is much cooler than taking drugs.C. They are affected by many other people around them.D. They can get liquor easily.2.According to the passage, what changes may happen to the kids who start drinking?A. Nothing serious will happen to them.B. They keep the same eating and sleeping habits.C. They can control their moods quite well.。

Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose.

In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here atthe University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5.

During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little.

Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has triedrepeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbd大学英语四级阅读理解试题40篇之六（含答案）As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves thesame response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbc大学英语四级阅读理解试题40篇之七（含答案）In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing."A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school husesand traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcb大学英语四级阅读理解试题40篇之八（含答案）There are two factors which determine an individual's intelligence. The first is the sort of brain heis born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc大学英语四级阅读理解试题40篇之九（含答案）As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：dbdcd大学英语四级阅读理解试题40篇之十（含答案）If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there. Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd大学英语四级阅读理解试题40篇之十一（含答案）What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up."。

大学英语四级阅读理解试题及答案（一）一There are three kinds of goals: short-term,medium-range and long-term goals.Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future. They might cover five years or more.

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical ye ar of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3.

Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist.

Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives close to that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests.

It was transferred from France to Spain, returned to France,and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it , and the Americans under General And rew Jackson.The riverbed of the Mississippi is constantly silting and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.Although New Orleans haas beena part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which,form many years,was its only law.New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting facade of yesteryear, is a busy industrial and port city. Grain and coal come from the Midwest and foreigh cargoes areunloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.1.What accounts for the levees and pumps in New Orleans?a.The Mississippi frequently floods the city.b.The riverbed has raised inthe past 200 years.c.The torrential rains flood the city frequently.d.The high humidity cannot otherwise be comtrolled.2.The battle of New Orleans was fought by jackson against______.a.Franceb.Britainc.Spaind.The North3.The Code Napoleon was _______.a.an agreement to sell Louisianab.a body of lawsc.a city pland.a military code for the army4.Which of the following elements does not apply to the attiude of the inhabitants of New Orleans?a.Pride in their French heritage.b.A desire to retain picturesque colonial buildings.c.A refusal to engage in trade and commerced.A praising of Dixieland Jazz.5.Tourists visiting New Orleans are surprised to encounter_____.a.Creole foodb.Dixieland jazzc.bustling cityd.authentic colonial homes答案：bbbcc十四The United States is on the verge of losing its leading place in the world's technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.Since 1976,employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds--the near term source of future PH.D.s-is declining. Further adding to the problem is the increased competition for these candidates from other fields-law,medicine,business,etc. While the number of U.S. PH.D.s in science and engineering declines,the award of PH.D.s to foreign nationals is increasing rapidly.Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor's and Master's degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.1.The U.S.will come to lose its leading place in technology probably because ________.a. the number of PH.D. degree holders is decliningb. the number of scientists and engineers is decreasingc. the number of 22-year-ilds is decliningd. scientists and engineers are not employed2.The field of science and engineering is facing a competition from ________ .a. technologyb. foreign nationalsc. such fields as law, medicine and businessd. postgraduatesrge-scale enterprises now need _______.a. bright graduates and postgraduatesb. new inventionsc. advanced technologyd. engineers4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.a. they are not encouraged to be engaged in scienceb. industry does not require PH.D. holdersc. they have financial difficultiesd. they will spend much time and energy completing PH.D.5.PH.D. candidates "find the attraction of industry irresistible" means that _________.a. they find industry is attracting more and more college studentsb. they don't think they can prevent themselves from working for industryc. they cannot resist any attraction from all sidesd. they cannot work for industry any longer答案：bcadb十五Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation's political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard of opwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America's industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in our society-government,industry,and education. That is not to say that the Defense Department will not be a strong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation's political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as a third-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4. America succeeded in shaping world events over past 40 years probably because of ___________.a. its ability to adapt technologyb. its ability to take advantage of the capabilities of its peoplec. its ability to compete in the world marketsd. both a and b5. The purpose of writing this article is __________.a. to draw the readers' attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess答案：dabdc。

大学英语四级阅读理解试题及答案（二）六As the pace of life continues to increase ,we are fast losing the art ofrelaxation. Once you are in the habit of rushing through lift,being on the go frommorning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. Infact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some p eople are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusualdifficulties. When e xposed to stress,in whatever form,we react both chemically and physically. In fact we make c hoice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the sameresponse. It is when such a reaction lasts long,through continued exposure tostress,that health becomes endangered.Such serious conditions as high bloodpressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager ishis ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"七In the 1960s, many y oung Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Someof them decided to "drop out" of American society and form their own societies .They formed utopian communities , which they called "communes," where they couldfollow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher andarchitect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo SanFrancisco poet Steve Gakin, and a group that called itself the Hog Farm, lived inold school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin'sfollowers tried to settle down on a farm in Tennessee, but they had to leave whensome members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however .Twin Oaks , a commune f ounded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefullycontrolled by Skinner's "conditioning" techniques to do things that were good forthe community. In 1972, Italian architect Paolo Soleri began to build Arcosanti,a utopian city Arizsona where 2500 people will live closely together in one largebuilding called an "archology" Soleri believes that people must live closelytogether so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people八There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some beingmore capable than others. But no matter how good a brain he has to begin with, anindividual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likelythat his brain will fail to develop and he will never attain the level of intelligenceof which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they wereplaced in separate foster homes. Peter was reated by parents of low intelligencein an isolatedcommunity with poor educational pooprtunities.Mark was reared inthehome of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.Thisenviromental difference continued until the twins were in their late teens, whenthey were giben tesets to measure their intelligence. Mark's I.Q. was 125,twenty-five points higher than the average and fully forty points higher than hisidentical brother. Given equal opportunities , the twins , having identicalbrains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood九As she walked round the huge department store,Edith reflected how difficult itwas to choose a suitable Christmas present for her father.She wish that he was aseasy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeableexperience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attraciveties were on display. "They are real silk," the assistant assured her, trying totempt her. "Worth double the price." But edit knew from past experience that herchoice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man h ad gathered round a counter. She found some g ood quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bundto please him.When s he got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry十If the population of the earth goes on increasing at its present rate, therewill eventually not be enough resources left to sustain life on the planet.By themiddle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus tolook for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem,however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted itwill be possible to change the atmophere of Venus and so create a new world almostas large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or coldatmospheres and at the same t ime produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in smallrockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen andcarbon.When t he algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain willeventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there。

大学英语四级阅读习题及答案大学英语四级阅读习题(一)1、A2、D3、C4、C5、B大学英语四级阅读习题答案Acculturation, which begins at birth, is the process of teaching new generations of children the customs and values of the parents culture. How people treat newborns, for example, can be indicative of cultural values. In the United States it is not uncommon for parents to put a newborn in a separate room that belongs only to the child. This helps to preserve parents privacy and allows the child to get used to having his or her own room, which is seen as a first step toward personal independence. Americans traditionally have held independence and a closely related value, individualism, in high esteem. Parents try to instill these prevailing values in their children. American English expresses these value preferences: children should "cut the (umbilical) cord" and are encouraged not to be "tied to their mothers apron strings." In the process of their socialization children learn to "look out for number one" and to "stand on their own two feet".Many children are taught at a very early age to make decisions and be responsible for their actions. Often children work for money outside the home as a first step to establishing autonomy. Nine-or ten-year-old children may deliver newspapers in their neighborhoods and save or spend their earnings. Teenagers (13 to 18 years) may baby-sit neighbors homes in order to earn a few dollar a week. Receiving a weekly allowance at an early age teaches children to budget their money, preparing them for future financial independence. Many parents believe that managing money helps children learn responsibility as well as appreciate the value of money.21. According to this passage, the way people treat newborns _____.A) is a sign of their customsB) is an indication of their level of knowledgeC) symbolizes their social systemD) varies from culture to culture22. The expression, "to cut the cord", is used to show that _____.A) children dont like their parentsB) parents dont feel close to their childrenC) parents would not like to live together with their childrenD) independence from ones family is an important personal goal in USA23. Children who are "tied to the apron strings" _____.A) are caught in their mothers apronsB) must always wear an apron when they eatC) are very dependent on their mothersD) are independent from their parents24. American people often let their children work for money outside the home at a very early age because _____.A) children have to earn money to help the familyB) they need more moneyC) they want them to begin establishing autonomyD) children have to save money for future use25. It can be inferred from this passage that _____.A) Americans are money loversB) Americans admire independenceC) Americans are good at decision-makingD) Americans are all responsible大学英语四级阅读习题(二)Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number.The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA, footballs international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFAs insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.21. The experiment conducted by the researcher was meant to ________.A) review the decisions of referees at the 1998 World CupB) analyse the causes of errors made by football refereesC) set a standard for football refereeingD) reexamine the rules for football refereeing22. The number of refereeing errors in the experimental matches was ________.A) slightly above averageB) higher than in the 1998 World CupC) quite unexpectedD) as high as in a standard match23. The findings of the experiment show that ________.A) errors are more likely when a referee keeps close to the ballB) the farther the referee is from the incident, the fewer the errorsC) the more slowly the referee runs, the more likely will errors occurD) errors are less likely when a referee stays in one spot24. The word “officials” (Line 2, Para. 4) most probably refers to ________.A) the researchers involved in the experimentB) the inspectors of the football tournamentC) the referees of the football tournamentD) the observers at the site of the experiment25. What is one of the possible conclusions of the experiment?A) The ideal retirement age for an experienced football referee is45.B) Age should not be the chief consideration in choosing a football referee.C) A football referee should be as young and energetic as possible.D) An experienced football referee can do well even when in poor physical condition.。

大学英语四级阅读理解练习题和答案解析大学英语四级阅读理解练习题：【原文】The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of silicate (硅酸盐) that are semi-molten at depth, and the thin, solid-surface crust There are two kinds of crust, a lower and denser oceanic crust and an upper，lighter continental crust found over only about 40 percent of the Earths surface. The rocks of the crust are of very different ages. Some continental rocks are over 3,000 million years old, while those of the ocean floor are less than 200 million years old. The crusts and the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appear to consist of about 15 rigid plates, 7 of which are very large. These plates move over the semi-molten lower mantleto produce all of the major topographical(地形学的)features of the Earth. Active zones where intense deformation occur are confined to the narrow, interconnecting boundaries of contact of the plates.There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform contacts where plates slide past each other. Newoceanic crust is formed along one or more margins of each plate by material issuing from deeper layers of the Earth s crust, for example, by volcanic eruptions (爆发) of lava (火山熔岩) at mid-ocean ridges. If at such a spreading contact the two plates support continents，a rift(裂缝) is formed that will gradually widen and become flooded by the tea. The Atlantic Ocean formed like this as the American and Afro-European plates moved in opposite directions. When two plates carrying continents collide, the continental blocks,too light to be drawn down, continue to float and therefore buckle (起褶皱) to form a mountain chain along the length of the margin of the plates.大学英语四级阅读理解练习题：【题目】Choose correct answers to the question:1.The Earths crust______.A.can be classified into two typesB.is formed along the margins of the platesC.consists of semi-molten rocksD.is about 70 to 100 kilometers thick2.The 15 plates of the Earth are formed from ___.A.the oceanic crusts and continental crustsB.the crusts and the mantleC.the crusts and the top and solid part of the mantleD.the continental crusts and the solid part of the mantle3.Seriously-deformed zones appear _______A.whenever the crusts move over mantleB.when the plates move towards each otherC.in the narrow boundaries where two plates meetD.to be the major topographical feature of the Earth4.According to the second paragraph, the formation of the Atlantic Ocean is the example of_______.A.spreading contactsB.the influence of volcanic eruptionsC.converging contactsD.transform contacts5.This passage is probably_______.A.a newspaper advertisementB.a chapter of a novelC.an excerpt from a textbookD.a scientific report of new findings大学英语四级阅读理解练习题：【答案】1.[A] 事实细节题。

大学英语4级真题Passage 1The endless debate about “work-life balance’’ often contains a hopeful footnote about stay-at-home dads. If American society and business won5t make it easier on future female leaders who choose to have children, there is still the ray of hope that increasing numbers of full-time fathers will. But based on today’s socioeconomic trends, this hope is, unfortunately, misguided.It’s true that the number of men who have left work to do their thing as full-time parents has doubled in a decade, but ifs still very small：only 0. 8% of married couples where the stay-at-home father was out of the labor force for a year. Even that percentage is likely inflated by men thrust into their caretaker role by a downsizing. This is simply not a large enough group to reduce the social stigma(污名)and force other adjustments necessary to supporting men in this decision, even if only for a relatively short time.Even shorter times away from work for working fathers are already difficult. A study found that 85% of new fathers take some time off after the birth of a child—but for all but a few, it’s a week or two at most. Meanwhile, the average for women who take leave is more than 10 weeks. Such choices impact who moves up in the organization. While you’re away, someone else is doing your work, making your sales, taking care of your customers. That can’t help you at work. It can only hurt you. Women, of course, face the same issues of returning after a long absence. But with many more women than men choosing to leave the workforce entirely to raise families, returning from an extended parental leave doesn’t raise as many eyebrows as it does for men.Women would make more if they didn't break their earning trajectory (轨迹）by leaving the workforce, or if higher-paying professions were more family-friendly. In the foreseeable future, stay- at-home fathers may make all the difference for individual families, but their presence won’t reduce the numbers of high-potential women who are forced to choose between family and career.56.What gives women a ray of hope to achieve work-life balance?A)More men taking an extended parental leave.B)Peopled changing attitudes towards family.C)More women entering business management.D)The improvement of their socioeconomic status.57.Why does the author say the hope for more full-time fathers is misguided?A)Women are better at taking care of children.B)Many men value work more than their family.C)Their number is too small to make a difference.D)Not many men have the chance to stay at home.58.Why do few men take a long parental leave?A)A long leave will have a negative impact on their career.B)They just have too many responsibilities to fulfill at work.C)The economic loss will be too much for their family to bear.D)They are likely to get fired if absent from work for too long.59.What is the most likely reaction to men returning from an extended parental leave?A) Jealousy. C) Admiration. B) Surprise.D) Sympathy.60.What does the author say about high-potential women in the not-too-distant future?A)They will benefit from the trend of more fathers staying at home.B)They will find high-paying professions a bit more family-friendly.C)They are unlikely to break their career trajectory to raise a family.D)They will still face the difficult choice between career and children.答案：BCABDPassage 2Some of the world’s most significant problems never hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of some of the world’s major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.The authors take a vast number of data points for the four most important crops :rice, wheat, com and soyabeans (大豆).They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in the 1990s and 2000s. There are two worrying features of the slowdown. One is that it has been particularly sharp in the world’s most(人口多的）countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency cannot be taken for granted if yields continue to slow down or reverse.Second, yield growth has been lower in wheat and rice than in com and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Com and soyabeans are more important as feed grains. The authors note that “we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world. ”, The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.Instead, it says, thanks to slowing population growth, land currently ploughed up for crops might be able to revert (回返）to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.61.What does the author try to draw attention to?A) Food riots and hunger in the world.C) The decline of the grain yield growth.B) News headlines in the leading media.D) The food supply in populous countries.62.Why does the author mention India and China in particular?A)Their self-sufficiency is vital to the stability of world food markets.B)Their food yields have begun to decrease sharply in recent years.C)Their big populations are causing worldwide concerns.D)Their food self-sufficiency has been taken for granted.63.What does the new study by the two universities say about recent crop improvement efforts?A)They fail to produce the same remarkable results as before the 1980s.B)They contribute a lot to the improvement of human food production.C)They play a major role in guaranteeing the food security of the world.D)They focus more on the increase of animal feed than human food grains.64.What does the Food and Agriculture Organisation say about world food production in thecoming decades?A)The growing population will greatly increase the pressure on world food supplies.B)The optimistic prediction about food production should be viewed with caution.C)The "slowdown of the growth in yields of major food crops will be reversed.D)The world will be able to feed its population without increasing farmland.65.How does the author view the argument of the Food and Agriculture Organisation?A)It is built on the findings of a new study.B)It is based on a doubtful assumption.C)It is backed by strong evidence.D)It is open to further discussion.答案：CADDBPassage 3Junk food is everywhere. We’re eating way too much of it. Most of us know what we’re doing and yet we do it anyway.So here’s a suggestion offered by two researchers at the Rand Corporation : Why not take a lesson from alcohol control policies and apply them to where food is sold and how it’s displayed?“Many policy measures to control obesity(肥胖症）assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods,” note the two researchers.“In contrast,” the researchers continue, “ many regulations that don’t assume people make rational choices have been successfully applied to control alcohol, a substance—like food—of which immoderate consumption leads to serious health problems. ’’The research references studies of peopled behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:Density restrictions：licenses to sell alcohol aren’t handed out unplanned to all comers but are allotted (分配) based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren5t primarily food stores?Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can’t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they’re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.56.What does the author say about junk food?A)People should be educated not to eat too much.B)It is widely consumed despite its ill reputation.C)Its temptation is too strong for people to resist.D)It causes more harm than is generally realized.57.What do the Rand researchers think of many of the policy measures to control obesity?A) They should be implemented effectively.C) They are based on wrong assumptions.B) They provide misleading information.D) They help people make rational choices.58.Why do policymakers of alcohol control place density restrictions?A)Few people are able to resist alcohol’s temptations.B)There are already too many stores selling alcohol.C)Drinking strong alcohol can cause social problems.D)Easy access leads to customers’ over-consumption.59.What is the purpose of California’s rule about alcohol display in gas stations?A)To effectively limit the density of alcohol outlets.B)To help drivers to give up the habit of drinking.C)To prevent possible traffic jams in nearby areas.D)To get alcohol out of drivers’ immediate sight.60.What is the general guideline the Rand researchers suggest about junk food control?A)Guiding people to make rational choices about food.B)Enhancing people’s awareness of their own health.C)Borrowing ideas from alcohol control measures.D)Resorting to economic, legal and psychological means.答案：CCDDCPassage 4Kodak’s decision to file for bankruptcy (破产）protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but ultimately failed to adapt to the digital revolution.Although many attribute Kodak’s downfall to “complacency ( 自满)”that explanation doesn’t acknowledge the lengths to which the company went to reinvent itself. Decades ago, Kodak anticipated that digital photography would overtake film—and in fact, Kodak invented the first digital camera in 1975—but in a fateful decision, the company chose to shelf its new discovery to focus on its traditional film business.It wasn’t that Kodak was blind to the future, said Rebecca Henderson, a professor at Harvard Business School, but rather that it failed to execute on a strategy to confront it. By the time the company realized its mistake, it was too late.Kodak is an example of a firm that was very much aware that they had to adapt, and spent a lot of money trying to do so, but ultimately failed. Large companies have a difficult time switching to new markets because there is a temptation to put existing assets into the new businesses.Although Kodak anticipated the inevitable rise of digital photography, its corporate(企业的）culture was too rooted in the successes of the past for it to make the clean break necessary to fully embrace the future. They were a company stuck in time. Their history was so important to them. Now their history has become a liability.Kodak’s downfall over the last several decades was dramatic. In 1976, the company commanded 90% of the market for photographic film and 85% of the market for cameras. But the 1980s brought new competition from Japanese film company Fuji Photo, which undermined Kodak by offering lower prices for film and photo supplies. Kodak’s decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major miscalculation. The bid went instead to Fuji, which exploited its sponsorship to win a permanent foothold in the marketplace.61.What do we learn about Kodak?A)It went bankrupt all of a sudden.B)It is approaching its downfall.C)It initiated the digital revolution in the film industry.D)It is playing the dominant role in the film market.62.Why does the author mention Kodak’s invention of the first digital camera?A)To show its early attempt to reinvent itself.B)To show its effort to overcome complacency.C)To show its quick adaptation to the digital revolution.D)To show its will to compete with Japan’s Fuji Photo.63.Why do large companies have difficulty switching to new markets?A)They find it costly to give up their existing assets.B)They tend to be slow in confronting new challenges.C)They are unwilling to invest in new technology.D)They are deeply stuck in their glorious past.64.What does the author say Kodak’s history has become?A) A burden.B) A mirror.C) A joke.D) A challenge.65.What was Kodak’s fatal mistake?A) Its blind faith in traditional photography.C) Its refusal to sponsor the 1984 Olympics.B) Its failure to see Fuji Photo’s emergence.D) Its overconfidence in its corporate culture.答案：BADACPassage 5When it’s five o’clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clock tells them they’re done.These days, the time is everywhere: not just on clocks or watches, but on cell-phones and computers. That may be a bad thing, particularly at work. New research shows that clock-based work schedules hinder morale (士气) and creativity.Clock-timers organize their day by blocks of minutes and hours. For example：a meeting from 9 a. m. to 10 a. m. , research from 10 a. m. to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities—from project planning, holiday shopping, to yoga —by time or to-do list to measure how they performed under “clock time vs “task time.” They found clock timers to be more efficient but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.The researchers argue that task-based organizing tends to be undervalued and under-supported in business culture. Smart companies, they believe, will try to bake more task-based planning into their strategies.This might be a small change to the way we view work and the office, but the researchersargue that it challenges a widespread characteristic of the economy: work organized by dock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when perfoming a job that requires more creativity. It’ll make those tasks easier, arid the task- doers will be happier.56.What does the author think of time displayed everywhere?A)It makes everybody time-conscious.B)It is a convenience for work and life.C)It may have a negative effect on creative work.D)It clearly indicates the fast pace of modem life.57.How do people usually go about their work according to the author?A)They combine clock-based and task-based planning.B)They give priority to the most urgent task on hand.C)They set a time limit for each specific task.D)They accomplish their tasks one by one.58.What did Tamar Avnet and Anne-Laure Sellier find in their experiments about clocks timers?A) They seize opportunities as they come up.C) They have more control over their lives.B) They always get their work done in time.D) They tend to be more productive.59.What do the researchers say about today’s business culture?A)It does not support the strategies adopted by smart companies.B)It does not attach enough importance to task-based practice.C)It places more emphasis on work efficiency than on workers5 lives.D)It aims to bring employees, potential and creativity into full play.60.What do the researchers suggest?A)Task-based timing is preferred for doing creative work. B)It is important to keep a balance between work and life.C)Performing creative jobs tends to make workers happier. D)A scientific standard should be adopted in job evaluation.答案：CADAAPassage 6Martha Stewart was charged, tried and competed of a crime in 2004. As she neared the end of her prison sentence, a well-known columnist wrote that she was “ paying her dues,” and that “ there is simply no reason for anyone to attempt to deny her right to start anew.”Surely, the American ideal of second chances should not be reserved only for the rich and powerful. Unfortunately, many federal and state laws impose post-conviction restrictions on a shockingly large number of Americans, who are prevented from ever fully paying their debt to society.At least 65 million people in the United States have a criminal record. This can result in severe penalties that continue long after punishment is completed.Many of these penalties are imposed regardless of the seriousness of the offense or the person’s individual circumstances. Laws can restrict or ban voting, access to public housing, and professional and business licensing. They can affect a person’s ability to get a job and qualification for benefits.In all, more than 45, 000 laws and rules serve to exclude vast numbers of people from fullyparticipating in American life.Some laws make sense. No one advocates letting someone convicted of pedophilia（恋童癖）work in a school. But too often collateral(附随的）consequences bear no relation to public safety. Should a woman who possessed a small amount of drugs years ago be permanently unable to be licensed as a nurse?These laws are also counterproductive, since they make it harder for people with criminal records to find housing or land a job, two key factors that reduce backsliding.A recent report makes several recommendations, including the abolition of most post-conviction penalties, except for those specifically needed to protect public safety. Where the penalties are not a must, they should be imposed only if the facts of a case support it.The point is not to excuse or forget the crime. Rather, it is to recognize that in America’s vast criminal justice system, second chances are crucial. It is in no one’s interest to keep a large segment of the population on the margins of society.61.What does the well-known columnist’s remark about Martha Stewart suggest?A)Her past record might stand in her way to a new life.B)Her business went bankrupt while she was in prison.C)Her release from prison has drawn little attention.D)Her prison sentence might have been extended.62.What do we learn from the second paragraph about many criminals in America?A)They backslide after serving their terms in prison.B)They are deprived of chances to turn over a new leaf.C)They receive severe penalties for committing minor offenses.D)They are convicted regardless of their individual circumstances.63.What are the consequences for many Americans with a criminal record?A) They remain poor for the rest of their lives.C) They are marginalized in society.B) They are deprived of all social benefits.D) They are deserted by their family.64.What does the author think of the post-conviction laws and rules?A)They help to maintain social stability.B)Some of them have long been outdated.C)They are hardly understood by the public.D)A lot of them have negative effects on society.65.What is the author’s main purpose in writing the passage?A)To create opportunities for criminals to reform themselves.B)To appeal for changes in America’s criminal justice system.C)To ensure that people with a criminal record live a decent life.D)To call people’s attention to prisoners’ conditions in America.答案：ABCDBPassage 7The wallet is heading for extinction. As a day-to-day essential，it will die off with the generation who read print newspapers. The kind of shopping—where you hand over notes and count out change in return—now happens only in the most minor of our retail encounters, like buying a bar of chocolate or a pint of milk from a comer shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher upthe scale you go. At the most cutting-edge retail stores—Victoria Beckham on Dover Street, for instance—you don’t go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.Which is nothing more or less than excellent service, if you have the money. But across society, the abstraction of the idea of cash makes me uneasy. Maybe I’m just old-fashioned. But earning money isn’t quick or easy for most of us. Isn’t it a bit weird that spending it should happen in half a blink (眨眼）of an eye? Doesn’t a wallet—that time-honoured Friday-night feeling of pleasing, promising fatness—represent something that matters?But I’ll leave the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet—the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets—is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass，smooth and unknowable as a pebble (鹅卵石）. Instead of digging through pieces of paper and peering into comers, we move our fingers left and right. No more counting out coins. Show your wallet, if you still have one. It may not be here much longer.56.What is happening to the wallet?A) It is disappearing.C) It is becoming costly,B) It is being fattened.D) It is changing in style.57.How are business transactions done in big modem stores?A)Individually.C) In the abstract.B)Electronically.D) Via a cash register.58.What makes the author feel uncomfortable nowadays?A)Saving money is becoming a thing of the past.B)The pleasing Friday-night feeling is fading.C)Earning money is getting more difficult.D)Spending money is so fast and easy.59.Why does the author choose to write about what’s happening to the wallet?A)It represents a change in the modem world.B)It has something to do with everybody’s life.C)It marks the end of a time-honoured tradition.D)It is the concern of contemporary economists.60.What can we infer from the passage about the author?A)He is resistant to social changes.B)He is against technological progress.C)He feels reluctant to part with the traditional wallet.D)He feels insecure in the ever-changing modem world.答案：ABDADPassage 8Everybody sleeps, but what people stay up late to catch—or wake up early in order not to miss— varies by culture.From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.Around the world, people changed sleep patterns thanks to the start or end of daylight savings time, Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to “winter time” starting on October 26.Russia’s other late nights and early mornings generally correspond to public holidays. On New Year’s Eve, Russians have the world’s latest bedtime，hitting the hay at around 3:30 a.m.、Russians also get up an hour later on International Women’s Day, the day for treating and celebrating female relatives.Similarly, Americans, late nights, late mornings, and longest sleeps fall on three-day weekends. Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey （冰球）. The World Cup is also chiefly responsible for sleep deprivation(剥夺）.The worst night for sleep in the U. K was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it’s likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that’s the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?61.What does the author say about peopled sleeping habits?A) They are culture-related.C) They change with the seasons.B) They affect peopled health.D) They vary from person to person.62.What do we learn about the Russians regarding sleep?A)They don’t fall asleep until very late.C)They get less sleep on public holidays.B)They don’t sleep much on weekends.D)They sleep longer than people elsewhere.63.What is the major cause for Europeans’ loss of sleep?A)The daylight savings time.C)The World Cup.B)The colorful night life.D)The summertime.64.What is the most probable reason for some rich people to use a device to record their sleep patterns?A) They have trouble falling asleep.C) They are involved in a sleep research.B) They want to get sufficient sleep.D) They want to go to bed on regular hours.65.What does .the author imply in the last paragraph?A)Sleeplessness does harm to peopled health.B)Few people really know the importance of sleep.C)It is important to study our sleep patterns.D)Average people probably sleep less than the rich.答案：ACCBBPassage 9Could you reproduce Silicon Valley elsewhere, or is there something unique about it?It wouldn't be surprising if it were hard to reproduce in other countries, because you couldn't reproduce it in most of the US either. What does it take to make a Silicon Valley?It's the right people. If you could get the right ten thousand people to move from Silicon Valley to Buffalo, Buffalo would become Silicon Valley.You only need two kinds of people to create a technology hub (中心) : rich people and nerds (痴迷科研的人).Observation bears this out. Within the US, towns have become star, up hubs if and only if they have both rich people and nerds. Few startups happen in Miami, for example, because although it's full of rich people, it has few nerds. It's not the kind of place nerds like.Whereas Pittsburgh has the opposite problem: plenty of nerds, but no rich people.The top US Computer Science departments are said to be MIT, Stanford, Berkeley, and Carnegie-Mellon. MIT yielded Route 128.Stanford and Berkeley yielded Silicon Valley. But what did Carnegie-Mellon yield in Pittsburgh? And what happened in Ithaca, home of Cornell University, which is also high on the list?I grew up in Pittsburgh and went to college at Cornell, so I can answer for both. The weather is terrible, particularly in winter, and there's no interesting old city to make up for it, as there is in Boston. Rich people don't want to live in Pittsburgh or Ithaca. So while there're plenty of hackers (电脑迷) who could start startups, there's no one to invest in themDo you really need the rich people? Wouldn't it work to have the government invest in the nerds?No, it would not. Start up investors are a distinct type of rich people. They tend to have a lot of experience themselves in the technology business. This helps them pick the right startups, and means they can supply advice and connections as well as money. And the fact that they have a personal stake in the outcome makes them really pay attention.56.What do we learn about Silicon Valley from the passage?A. Its success is hard to copy anywhere else.B. It is the biggest technology hub in the US.C. Its fame in high technology is incomparable.D. It leads the world in information technology.57.What makes Miami unfit to produce a Silicon Valley?A. Lack of incentive for investment.B. Lack of the right kind of talents.C. Lack of government support.D. Lack of famous universities.58.In what way is Carnegie-Mellon different from Stanford, Berkeley and MIT?A. Its location is not as attractive to rich people.B. Its science departments are not nearly as good.C. It does not produce computer hackers and nerds.D. It does not pay much attention to business startups.59.What does the author imply about Boston?A. It has pleasant weather all year round.。

大学英语四级阅读理解试题40篇之一（含答案）There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed.

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. Butthere were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agricula tural Trends of 1950’sb.

In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs. College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist. "Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 19852c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5.

During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very little3b.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb大学英语四级阅读理解试题40篇之五（含答案）The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbd大学英语四级阅读理解试题40篇之六（含答案）As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.4Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbc大学英语四级阅读理解试题40篇之七（含答案）In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and5architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcb大学英语四级阅读理解试题40篇之八（含答案）There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.6The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc大学英语四级阅读理解试题40篇之九（含答案）As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.7Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking."

But none of the other planets in our solar system are capable of8supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on V enus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd大学英语四级阅读理解试题40篇之十一（含答案）What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is9depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london to others because of _______.a.its shapeb.its structurec.its colourd.its building materials答案：bcaac大学英语四级阅读理解试题40篇之十二（含答案）Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives close to that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. When the food was served , one of the guests strated to eat his peas with a knife . The other guests were amused or shocked , but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.10。

大学生英语四级考试阅读理解试题及答案解析1The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon.This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995.The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions.Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year.The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means.21. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.A. housingB. foodC. povertyD. limited land22. According to the passage, "about US $116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. " Do you think which year was the article written by saying "less than $ 10 billion per year" by theturn of the century?A. 1985.B. 1990.C. 1988.D. 2000.23. The mankind should face the phenomenon that the world has become a world of cities with______.A. a lot of difficultiesB. efforts to improve housing conditionC. pressure of the basic needsD. new models and a great deal of transformation of ideas and methods24. In Africa, people in cities will be______by the end of the century.A. almost twice as much as in 1985B. doubled than that in 1985C. over twice as much as in 1985D. 300 million25. In spite of the efforts to improve housing condition, the number of people living in shanty-towns will increase because______.A. houses in shanty-towns are cheapB. shanty-towns could provide people with minimum comfortC. no policy will be capable of stopping or changing the present immigrant tendency from the rural areas to the cities in the Third WorldD. the Third Word population is growing at a rate of about 80 million people per year答案：21.

Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief inyour ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase. Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action. 1.Our long-term goals mean a lot______.A.if we complete our short-range goalsB.if we cannot reach solid short-term goalsC.if we write down the datesD.if we put forward some plans2.New short-term goals are bulid upon______.A.two yearsB.long-term goalsC.current activitiesD.the goals that have been completed3.When we complete each step of our goals ,______.A.we will win final successB.we are overwhelmedC.we should build up confidence of successD.we should strong desire for setting new goals 4.Once our goals are drawn up,_______.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC.we had better wait for the exciting news of successD.we have made great decision5.It is implied but not stated in the passage that ______.A.those who habe long-term goals will succeedB.writing down the dates may discourage youC.the goal is only a guide for us to reach our desinationD.every should have a goal答案：adcbc大学生英语四级考试阅读理解试题及答案解析4Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised. First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally,thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb【大学生英语四级考试阅读理解试题及答案解析】。

more capable than others. but no matter how good a brain he has to begin with,an individual will have a low order of intelligence unless hehas opportunities to learn.so the second factor is what happens to the individual—the sort of environment in which he is reared. if an individual is handicapped envionmentally ,it is likely that his brain will failto develop and he will never attain the level of intelligence ofwhich he is capable.the importance of environment in determining an individuals intellingence can be demonstrated by the case history of the identical twins, peter and mark x. being identical, the twins had identical brains at birth, and their growth processes were the same. when the twins were three months old , their parentsdied, and they were placed in separate foster homes. peter was reated by parents of low intelligence in an isolatedcommunitywith poor educational pooprtunities.mark was reared inthehome of well-to-do parents who had been to college. he wasread to

大学英语四级试练习卷一、阅读理解阅读理解（一）The earliest controversies about the relationship between photography and art centered on whether photograph’s fidelity to appearances and dependence on a machine allowed it to be a fine art as distinct from merely a practical art. Throughout the nineteenth century, the defence of photography was identical with the struggle to establish it as a fine art. Against the charge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing, a revolt against commonplace vision, and no less worthy an art than painting.Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves—anything but making works of art. They are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art. It shows the extent to which they simply take for granted the concept of art imposed by the triumph of Modernism: the better the art, the more subversive it is of the traditional aimsof art.Photographers’ disclaimers of any interest in making art tell us more about the harried status of the contemporary notion of art than about whether photography is or is not art. For example, those photographers who suppose that, by taking pictures, they are getting away from the pretensions of art as exemplified by painting remind us of those Abstract Expressionist painters who imagined they were getting away from the intellectual austerity of classical Modernist painting by concentrating on the physical act of painting. Much of photography’s prestige today derives from the convergence of its aims with those of recent art, particularly with the dismissal of abstract art implicit in the phenomenon of Pop painting during the 1960’s. Appreciating photographs is a relief to sensibilities tired of the mental exertions demanded by abstract art. Classical Modernist painting—that is, abstract art as developed in different ways by Picasso, Kandinsky, and Matisse—presupposes highly developed skills of looking and a familiarity with other paintings and the history of art. Photography, like Pop painting, reassures viewers that art is not hard; photography seems to be more about its subjects than about art.Photography, however, has developed all the anxieties andself-consciousness of a classic Modernist art. Many professionals privately have begun to worry that the promotion of photography as anactivity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity—in short, an art.1. What is the author mainly concerned with? The author is concerned with[A]. defining the Modernist attitude toward art.[B]. explaining how photography emerged as a fine art.[C]. explaining the attitude of serious contemporary photographers toward photography as art and placing those attitudes in their historical context.[D]. defining the various approaches that serious contemporary photographers take toward their art and assessing the value of each of those approaches.2. Which of the following adjectives best describes “the concept of art imposed by the triumph of Modernism” as the author represents it in lines 12—13?[A]. Objective [B]. Mechanical. [C]. Superficial. [D]. Paradoxical.3. Why does the author introduce Abstract Expressionist painter?[A]. He wants to provide an example of artists who, like serious contemporary photographers, disavowed traditionally accepted aims of modern art.[B]. He wants to set forth an analogy between the Abstract Expressionist painters and classical Modernist painters.[C]. He wants to provide a contrast to Pop artist and others.[D]. He wants to provide an explanation of why serious photography, like other contemporary visual forms, is not and should not pretend to be an art.4. How did the nineteenth-century defenders of photography stress the photography?[A]. They stressed photography was a means of making people happy.[B]. It was art for recording the world.[C]. It was a device for observing the world impartially.[D]. It was an art comparable to painting.阅读理解（二）Nearly two thousand years have passed since a census decreed by Caesar Augustus become part of the greatest story ever told. Many things have changed in the intervening years. The hotel industry worries more about overbuilding than overcrowding, and if they had to meet an unexpected influx, few inns would have a manager to accommodate the weary guests. Now it is the census taker that does the traveling in the fond hope that a highly mobile population will stay long enough to get a good sampling. Methods of gathering, recording, and evaluating information have presumably been improved a great deal. And where then it was the modest purpose of Rome to obtain a simple head count as an adequate basis for levying taxes, now batteries of complicated statistical series furnishedby governmental agencies and private organizations are eagerly scanned and interpreted by sages and seers to get a clue to future events. The Bible does not tell us how the Roman census takers made out, and as regards our more immediate concern, the reliability of present day economic forecasting, there are considerable differences of opinion. They were aired at the celebration of the 125th anniversary of the American Statistical Association. There was the thought that business forecasting might well be on its way from an art to a science, and some speakers talked about newfangled computers and high-falutin mathematical system in terms of excitement and endearment which we, at least in our younger years when these things mattered, would have associated more readily with the description of a fair maiden. But others pointed to the deplorable record of highly esteemed forecasts and forecasters with a batting average below that of the Mets, and the President-elect of the Association cautioned that “high powered statistical methods are usually in order where the facts are crude and inadequate, the exact contrary of what crude and inadequate statisticians assume.” We left his birthday party somewhere between hope and despair and with the conviction, not really newly acquired, that proper statistical methods applied to ascertainable facts have their merits in economic forecasting as long as neither forecaster nor public is deluded into mistaking the delineation of probabilities and trends for a prediction of certainties of mathematical exactitude.1. Taxation in Roman days apparently was based on[A]. wealth. [B]. mobility. [C]. population. [D]. census takers.2. The American Statistical Association[A]. is converting statistical study from an art to a science.[B]. has an excellent record in business forecasting.[C]. is neither hopeful nor pessimistic.[D]. speaks with mathematical exactitude.3. The message the author wishes the reader to get is[A]. statisticians have not advanced since the days of the Roman.[B]. statistics is not as yet a science.[C]. statisticians love their machine.[D].computer is hopeful.4. The “greatest story ever told” referred to in the passage is the story of[A]. Christmas. [B]. The Mets.[C]. Moses. [D]. Roman Census Takers.二、完型填空完型填空（一）Most parents, I suppose, have had the experience of reading a bedtime story to their children.And they must have 1 how difficult it is to write a 2 children’s book.Either the author has aimed too 3 , so that the children can’t follow what is in his (or more often, her) story, 4 thestory seems to be talking tothe readers.

大学英语四级试练习卷一、阅读理解阅读理解（一）Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis,by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.The attempt to discover the explanation of this phenomenon in the antithesis of “facts” and “theories” or “facts” and “ideas”—in the neglect among the ancients of the former, and their too exclusive attention to the latter —proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories. Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on theother hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact."1. The title that best expresses the ideas of this passage is"[A]. Philosophy of mathematics. [B]. The Recent Growth in Science.[C]. The Verification of Facts. [C]. Methods of Scientific Inquiry."2. According to the author, one possible reason for the growth of science during the days of the ancient Greeks and in modern times is"[A]. the similarity between the two periods.[B]. that it was an act of God.[C]. that both tried to develop the inductive method.[D]. due to the decline of the deductive method."3. The difference between “fact” and “theory”"[A]. is that the latter needs confirmation.[B]. rests on the simplicity of the former.[C]. is the difference between the modern scientists and the ancient Greeks.[D]. helps us to understand the deductive method."4. According to the author, mathematics is"[A]. an inductive science. [B]. in need of simple verification.[C]. a deductive science. [D]. based on fact and theory."5. The statement “Theories are facts” may be called."[A]. a metaphor. [B]. a paradox.[C]. an appraisal of the inductive and deductive methods.[D]. a pun.阅读理解（二）On the 36th day after they had voted, Americans finally learned Wednesday who would be their next president: Governor George W. Bush of Texas.Vice President Al Gore, his last realistic avenue for legal challenge closed by a U. S. Supreme Court decision late Tuesday, planned to end the contest formally in a televised evening speech of perhaps 10 minutes, advisers said. They said that Senator Joseph Lieberman, his vice presidential running mate, would first make brief comments. The men would speak from a ceremonial chamber of the Old Executive office Building, to the west of the White House.The dozens of political workers and lawyers who had helped lead Mr. Gore’s unprecedented fight to claw a come-from-behind electoral victory in the pivotal state of Florida were thanked Wednesday and asked to stand down. “The vice president has directed the recount committee to suspend activities,”William Daley, the Gore campaign chairman, said in a written statement. Mr. Gore authorized that statement after meeting with his wife, Tipper, and with top advisers including Mr. Daley.He was expected to telephone Mr. Bush during the day. The Bush campaign kept a low profile and moved gingerly, as if to leave space for Mr. Gore to contemplate his next steps.Yet, at the end of a trying and tumultuous process that had focused world attention on sleepless vote counters across Florida, and on courtrooms formMiami to Tallahassee to Atlanta to Washington the Texas governor was set to become the 43d U. S. president.The news of Mr. Gore’s plans followed the longest and most rancorous dispute over a U. S. presidential election in more than a century, one certain to leave scars in a badly divided country.It was a bitter ending for Mr. Gore, who had outpolled Mr. Bush nationwide by some 300000 votes, but, without Florida, fell short in the Electoral College by 271votes to 267—the narrowest Electoral College victory since the turbulent election of 1876.Mr. Gore was said to be distressed by what he and many Democratic activists felt was a partisan decision from the nation’s highest court.The 5-to –4 decision of the Supreme Court held, in essence, that while a vote recount in Florida could be conducted in legal and constitutional fashion, as Mr. Gore had sought, this could not be done by the Dec. 12 deadline for states to select their presidential electors.James Baker 3rd, the former secretary of state who represented Mr. Bush in the Florida dispute, issued a short statement after the U. S. high court ruling, saying that the governor was “very pleased and gratified.”Mr. Bush was planning a nationwide speech aimed at trying to begin to heal the country’s deep, aching and varied divisions. He then was expected to meet with congressional leaders, including Democrats. Dick Cheney, Mr. Bush’s ruing mate, was meeting with congressmen Wednesday in Washington.When Mr. Bush, who is 54, is sworn into office on Jan.20, he will be only the second son of a president to follow his father to the White House, after JohnAdams and John Quincy Adams in the early 19th century.Mr. Gore, in his speech, was expected to thank his supporters, defend his hive-week battle as an effort to ensure, as a matter of principle, that every vote be counted, and call for the nation to join behind the new president. He was described by an aide as “resolved and resigned.”While some constitutional experts had said they believed states could present electors as late as Dec. 18, the U. S. high court made clear that it saw no such leeway.The U.S. high court sent back “for revision” to the Florida court its order allowing recounts but made clear that for all practical purposes the election was over.In its unsigned main opinion, the court declared, “The recount process, in its features here described, is inconsistent with the minimum procedures necessary to protect the fundamental right of each voter.”That decision, by a court fractured along philosophical lines, left one liberal justice charging that the high court’s proceedings bore a political taint.Justice John Paul Stevens wrote in an angry dissent:” Although we may never know with complete certainty the identity of the winner of this year’s presidential election, the identity of the loser is perfectly clear. It is the nation’s confidence in the judge as an impartial guardian of the law.”But at the end of five seemingly endless weeks, during which the physical, legal and constitutional machines of the U. S. election were pressed and sorely tested in ways unseen in more than a century, the system finally produced aresult, and one most Americans appeared to be willing at lease provisionally to support.The Bush team welcomed the news with an outward show of restraint and aplomb. The governor’s hopes had risen and fallen so many times since Election night, and the legal warriors of each side suffered through so many dramatic reversals, that there was little energy left for celebration."1. The main idea of this passage is"[A]. Bush’s victory in presidential election bore a political taint.[B]. The process of the American presidential election.[C]. The Supreme Court plays a very important part in the presidential election.[D]. Gore is distressed."2. What does the sentence “as if to leave space for Mr. Gore to contemplate his next step” mean"[A]. Bush hopes Gore to join his administration.[B]. Bush hopes Gore to concede defeat and to support him.[C]. Bush hopes Gore to congraduate him.[D]. Bush hopes Gore go on fighting with him."3. Why couldn’t Mr. Gore win the presidential election after he outpolled Mr. Bush in the popular vote? Because"[A]. the American president is decided by the supreme court’s decision.[B]. people can’t directly elect their president.[C]. the American president is elected by a slate of presidential electors.[D]. the people of each state support Mr. Bush."4. What was the result of the 5—4 decision of the supreme court?"[A]. It was in fact for the vote recount.[B]. It had nothing to do with the presidential election.[C]. It decided the fate of the winner.[D]. It was in essence against the vote recount."5. What did the “turbulent election of 1876” imply?"[A]. The process of presidential election of 2000 was the same as that.[B]. There were great similarities between the two presidential elections (2000 and 1876).[C]. It was compared to presidential election of 2000.[D]. It was given an example.阅读理解（三）Asked to name their favorite city, many Amerians would select San Francisco began as a small Spanish outpost located on a magnificent bay.The town was little more than a village serving ranchers when the United States took possession of it in 1846 during the war with Mexico. San Francisco sprang into a city overnight because of the nearby discovery of gold in 1848.A great rush to California took place.Wagon trains plodded their dangerous way across 2000 miles of prairie and mountains,while hundreds of sailing vessels made the equally hazardous trip around the Horn.The vessels disgorged thousands of passengers -- then the crews deserted teir ship and hundreds of vessels were left to rot in thebay.Within two years,California had enough population to become a state and San Francisco was for many years the hub of that newly-arrived population.The city’s present popularity is due to an excellent climate, an easy style of living ,good food,and numerous tourist attractions. The city is famous for its cable cars which "clang and bang" up the steep hills,and for its excellent seafood stals along the wharf. Most visitors arriving from nations in the Pacific Basin spend several days getting to know the town.1.According to this article, who were the first Californians?A.deserters from sailing shipsB.spanish ranchersC.gold minersD.tourists2.san francisco’s appeal includes all of the following factors____.A.attractive lifestyle,good seafood,desirable weatherB.tourist attactions,extreme seasons,cable carsC.wagon trains,gold mining,good climateD.cable cars,pleasent climate,flat terrain3.san francisco today is a thriving city because of ____.A.heavy industryernmental headquartersC.goldminingD.trade and tourism4.In waht year did California become an American state?A.1850B.1852C.1846D.1848二、完型填空完型填空（一）If you were to begin a new job tomorrow, you would bring with you some basic strengths andweaknesses.

大学英语四级阅读理解试题及答案（二）六As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed推想，料想 to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in morethe art of relaxationsense of responsibilitycontrol over performanceof the follwing statements is turecan find some ways to avoid stressis always harmful to peopleis easy to change the hagit of keeping oneself busy with work.people can withstand different amounts of stressParagraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbc七In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the . epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin'sfollowers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.did some young Americans decide to "drop out" of scoiety during the 1960swere not satisfied with American society.wanted to grow marijuana.wanted to go to the Vietnam War.did not want all people to be equal.did the members of the Hog Farm commune livedome-shaped houseold school husesa farm inTennesseean archology in Arizonagave the people of Drop City the idea to bulid dome-shaped houseSoleriGaskinFullerwas the Twin Oaks commune base onphilosophy of "do your own thing"in the late 1960sideas of psychologistbelief that people must live closely togerher.is an "archology"person who studies archaeologylarge building where people live closely togethercity in A rizonatechnique to contorl people答案：abdcb八There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Beingidentical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's . was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.selection can best be titled_________.Your Intelligenceand EnvironmentCase of Peter and Markthe brain Influences Intelligencebeststatement of the main idea of this passage is that _____.brains differ considerablybrain a person is born with is improtant in determining his intelligenceis crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligenceto the passage , the average _____.case history of the twins appears to support the conclusion that _______.with identical brains seldom test at same level individual's intelligence is determined only by his enviromentof opportunity blocks the growth of intelligenceof enviroment produce changes in the structure of the brainpassage suggests that an individual 's be predicted at birththe same throuthout his lifebe increased by educationdetermined by his childhood答案：bcbcc九As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.'s father _______.not like presentgot presenttiesdifficult to choose a present forassistant spoke to Edith because she seemed_______. in tiesneed of comfortstopped at the next counter_________.'s father smoked a pipe_______.he was obligedsocial occasionstime to timehe was delightedwas very disagreeable at that time of the year because_______.trod on each other's toespoked each other with their elbowsknocked each otherwere doing their shopping in a great hurry答案：dbdcd Research by the University of Exeter1 has revealed that ants have a big impact on their local environment as a result of their activity as "ecosystem engineers" and predators（食肉动物）. The study, published in the Journal of Animal Ecology, found that ants have two distinct（显著的）effects on their local environment.Firstly, through moving of soil by nest building2 activity and by collecting food they affect the level of nutrients（营养物）in the soil. This can indirectly impact the local populations of many animal groups, from decomposers（腐生物,分解体）to species much higher up the food chain.Secondly, they prey(捕食) on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant workers.Dirk Sanders, an author of the study from the university’s Centre for Ecology and Conservation, said: "Ants are very effective predators which thrive in huge numbers. They’re also very territorial3 and very aggressive, defen ding their resources and territory against other predators. All of this means they have a strong influence on their surrounding area.""In this research, we studied for the first time how big this impact is and the subtleties(微妙) of it. What we found is that despite being predators, their presence can also lead to an increase in density and diversity of other animal groups4. They genuinely play a key role in the local environment, having a big influence on the grassland food web," Sanders said.The study, carried out in Germany, studied the impact of the presence of different combinations and densities of black garden ants and common red ants, both species which can be found across Europe, including in the UK. It found that a low density of ants in an area increased the diversity anddensity of other animals in the local area, particularly the density of herbivores(食草动物) and decomposers. At higher densities ants had no or the opposite effect, showing that predation is counteracting the positive influence.Dr Frank van Veen, another author on the study, said: "What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect —thereby counteracting the positive influence via ecosystem engineering."Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5 (生物量) but also because they act as ecosystem engineers. Ant biodiversity6（生物多样性）is incredibly high and these organisms are highly responsive（敏感的，易受影响的） to human impact, which obviously reduces its richness. However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem7．Ants are important in below ground processes8 through the alteration of the physical and chemical environment and through their effects on plants, microorganisms, and other soil organismsThe standardized educational or psychological tests, which are widely used to aid in selecting, assigning or promoting students, employees and military personnel, have been the target of recent attacks in books, magazines, the daily press, and even in Congress. The target is wrong, for, in attacking the tests, critics divert attention from the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools. Whether the results will be valuable, meaningless, or even misleading depends partly upon the tool itself but largely upon the user.All informed predictions of future performance are based upon some knowledge of relevant past performance. How well the predictions will be validated by later performance depends upon the amount, reliability and appropriateness of the information used and on the skill and wisdom with which it is interpreted. Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error.Standardized tests should be considered in this context: they provide a quick, objective method of getting some kind of information about what a person has learned, the skills he hasdeveloped, or the kind of person he is. The information so obtained has, qualitatively, the same advantages and shortcomings as other kinds of information. Whether to use tests, other kinds of information, or both in a particular situation depends, therefore, upon the empirical evidence concerning comparative validity and upon such factors as cost and availability.In general, the tests work most effectively when the traits or qualities to be measured can be most precisely defined ( for example, ability to do well in a particular course of training program ) and least effectively when what is to be measured or predicted cannot be well defined, for example, personality or creativity. Properly used, they provide a rapid means of getting comparable information about many people. Sometimes they identify students whose high potential has not been previously recognized.The modern sailing ship was developed by a man who never went to sea.He was Prince Henry of Portugal,the younger son of the Partuguese king and an English princess.Prince Henry lived in the fifteenth a boy he became devoted to the sea,and he dedicated himself to improving the design of ships and the methods of sailing 1416,when he was twenty two,Henry founded a school for mariners, to which he invited everyone who could help him—Jewish astronomers,Italian and Spanish sailors, and Arab mathematicians and map makers who knew to use the crude compass of the day and could improve it.Henry’s goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the caravel carried more sail and was longer and slimmer than any ship then made,yet was tough enough to withstand gales at also developed the carrack,which was a slower ship,but one that was capable of carrying more cargo.To Prince Henry the world owes credit for development of craft that made oceanic exploration lives in history as Henry the Navigator.The modern sailing ship was developed by a man who never went to sea.He was Prince Henry of Portugal,the younger son of the Partuguese king and an English princess.Prince Henry lived in the fifteenth a boy he became devoted to the sea,and he dedicated himself to improving the design of ships and the methods of sailing 1416,when he was twenty two,Henry founded a school for mariners, to which he invited everyone who could help him—Jewish astronomers,Italian and Spanish sailors, and Arab mathematicians and map makers who knew to use the crude compass of the day and could improve it.Henry’s goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the caravel carried more sail and was longer and slimmer than any ship then made,yet was tough enough to withstand gales at also developed the carrack,which was a slower ship,but one that was capable of carrying more cargo.To Prince Henry the world owes credit for development of craft that made oceanic exploration lives in history as Henry the Navigator.十Now let us look at how we read. When we read a printed text, our eyes move across a page in short, jerky movement. We recognize words usually when our eyes are still when they fixate. Each time they fixate, we see a group of words. This is known as the recognition span or the visual span. The length of time ofr which the eyes stop ---the duration of the fixation ----varies considerably from person to person. It also vaies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness.Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation. All these exercises are very clever, butit’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous textIf the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change theatmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.Sagan believes that Venus might be colonized from earth because _____might be possible to change its atmosphereatmosphere is the same as the earth'sis a good supply of water on Venusdays on Venus are long enoughVenus there is a lot of ________.dioxidemonoxideare plants that can____.in very hot temperaturesin very cold temperaturesoxygenof the above5. Man can land on Venus only when_______.algae have done their workatmosphere becomes cooleroxygenrains there答案：cabddHeroin addictions today is found chiefly among young men of minority groups in ghetto(犹太人区) the more than 60,000 known addicts,more than half live in New York of them live in New York figures show that more than half of the addicts are under 30 years of age.Narcotic addiction in the United States is not limted to heroin middle-aged and older people who take narcotic drugs regularly to relieve pain can also become do some people who can get drugs easily,such as doctors,nurses,and show that this type of addict has personality and emotional problems very similar to those of other regular narcotic users.Many addicts admit that getting a continued supply is the main object of their addict’s concentration on getting drugs often prevents continuing an education or working at a health is often may be sick one day from the effects of withdrawal and sick the next day from an show that an addict’s life span may be shortened by 15 to 20 addict is usually in trouble with the family and almost always in trouble with the law.Some studies suggest that many of the known narcotic addicts had some trouble with the law before they became addicted,they may become even more involved with crime because it costs so much to support the heroin habit.Most authorities agree that the addict’s involvement with crime is not a direct effect of the drug to crime is usually the only way to get that much addicts’ crimes are nearly always thefts or other crimes against property.Federal penalties for illegal narcotics usage were established under the Harris on Act of Act provides that illegal possession of narcotics is punishable by fines and/or can range from 2 to 10 years for the first offense,5 to 20 years for the second,and 10 to 20 years for further offenses.Illegal sale of narcotics can mean a fine of $20,000 and a sentence from 20 to 40 years for later person who sells narcotics to someone under 18 is refused parole and probation,even for the first the drug is heroin,he can be sentenced to life imprisonment or to death.Scientists say they have discovered hints of alien life on the Saturn's moon. The discovery of a sort of life was announced after researchers at the US space agency,NASA,analyzed data from spacecraft Cassini,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" in Titan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs" consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consumeoxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists have not yet detected this form of life anywhere,though there are liquid- water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin(minus 290 degrees Farenheit),a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator of the NASA Titan team."Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."1. Passage OneUnless we spend money to spot and prevent asteroids(小行星)now，one might crash into Earth and destroy life as we know it，say some scientists.Asteroids are bigger versions of the meteoroids(流星)that race across the night orbit the sun far from Earth and don't threaten there are also thousands whose orbits put them on a collision course with Earth.Buy $ 50 million worth of new telescopes right spend $ 10 million a year for the next 25 years to locate most of the space the time we spot a fatal one，the scientists say，we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear the cost wouldn't be cheap.Is it worth it Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500，000 years. Sounds pretty rare-but if one did fall，it would be the end of the world.“If we don't take care of these big asteroids，they'll take care of us，”says one scientist.“It's that simple.”The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth“The world has less to fear fromdoomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article.21. What does the passage say about asteroids and meteoroidsA) They are heavenly bodies different in composition.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroids.[答案及分析]：［B］文章第二段第一句明确指出“小行星和划破夜空的流星是性质一样的物质，只是体积大些。
