北京航空航天大学考博英语模拟试卷13(题后含答案及解析)题型有：1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionPity those who aspire to put the initials PhD after their names. After 16 years of closely supervised e-ducation,prospective doctors of philosophy are left more or less alone to write the equivalent of a large book. Most social-science postgraduates have still not completed their theses by the time their grant runs out after three years. They must then get a job and finish in their spare time,which can often take a further three years. By then,most new doctors are sick to death of the narrowly defined subject which has blighted their holidays and ruined their evenings. The Economic and Social Research Council,which gives grants to postgraduate social scientists, wants to get better value for money by cutting short this agony. It would like to see faster completion rates:until recently,only about 25 points of PhD candidates were finishing within four years. The ESRC’s response has been to stop PhD grants to all institutions where the proportion taking less than four years is below 10 points;in the first year of this policy the national average shot up to 39 points. The ESRC feels vindicated in its toughness,and will progressively raise the threshold to 40 points in two years. Unless completion rates improve further,this would exclude 55 out of 73 universities and polytechnics-including Oxford University,the London School of Economics and the London Business School. Predictably,howls of protest have come from the universities,who view the blacklisting of whole institutions as arbitrary and negative. They point out that many of the best students go quickly into jobs where they can apply their research skills,but consequently take longer to finish their theses. Polytechnics with as few as two PhD candidates complain that they are penalized by random fluctuations in student performance. The colleges say there is no hard evidence to prove that faster completion rates result from greater efficiency rather than lower standards or less ambitious doctoral topics. The ESRC thinks it might not be a bad thing if PhD students were more modest in their aims. It would prefer to see more systematic teaching of research skills and fewer unrealistic expectations placed on young men and women who are undertaking their first piece of serious research. So in future its grants will be given only where it is convinced that students are being trained as researchers, rather than carrying out purely knowledge-based studies. The ESRC can not dictate the standard of thesis required by external examiners,or force departments to give graduates more teaching time. The most it can do is to try to persuade universities to change their ways. Recalcitrant professors should note that students want more research training and a less elaborate style of thesis,too.1．By time new doctors get a job and try to finish their theses in spare time,_____.A．most of them died of some sicknessB．their holidays and evenings have been ruined by their jobsC．most of them are completely tired of the narrowly defined subjectD．most of their grants run out正确答案：D解析：题目问：新的医生在找到工作并利用业余时间写论文时，发生了什么情况?第一段第三、四句“Mostsocial-science postgraduates have still not completed their theses by the time their grant runs out afterthree years．They must then get a job and finish in their spare time，which can often take a further threeyears．”通过这段话可知。

2008年北京航空航天大学考博英语真题试卷(题后含答案及解析)题型有：1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionThere has been a lot of hand-wringing over the death of Elizabeth Steinberg. Without blaming anyone in particular, neighbors, friends, social workers, the police and newspaper editors have struggled to define the community’s responsibility to Elizabeth and to other battered children. As the collective soul-searching continues, there is a pervading sense that the system failed her. The fact is, in New York State the system couldn’t have saved her. It is almost impossible to protect a child from violent parents, especially if they are white, middle-class, well-educated and represented by counsel. Why does the state permit violence against Children? There are a number of reasons. First, parental privilege is a rationalization. In the past, the law was giving its approval to the biblical injunction against sparing the rod. Second, while everyone agrees that the state must act to remove children from their homes when there is danger of serious physical or emotional harm, many child advocates believe that state intervention in the absence of serious injury is more harmful than helpful. Third, courts and legislatures tread carefully when their actions intrude or threaten to intrude on a relationship protected by the Constitution. In 1923, the Supreme Court recognized the “liberty of parent and guardian to direct the upbringing and education of children under their control”. More recently, in 1977, it upheld the teacher’s privilege to use corporal punishment against schoolchildren. Read together, these decisions give the constitutional imprimatur to parental use of physical force. Under the best conditions, small children depend utterly on their parents for survival. Under the worst, their dependency dooms them. While it is questionable whether anyone or anything could have saved Elizabeth Steinberg, it is plain that the law provided no protection. To the contrary, by justifying the use of physical force against children as an acceptable method of education and control, the law lent a measure of plausibility and legitimacy to her parents’conduct. More than 80 years ago, in the teeth of parental resistance and Supreme Court doctrine, the New York State Legislature acted to eliminate child labor law. Now, the state must act to eliminate child abuse by banning corporal punishment. To break the vicious cycle of violence, nothing less will answer. If there is a lesson to be drawn from the death of Elizabeth Steinberg, it is this: spare the rod and spare the child.1．The New York State law seems to provide least protection of a child from violent parents of______A．a family on welfareB．a poor uneducated familyC．an educated black familyD．a middle-class white family正确答案：D解析：细节题。

北京航天航空大学考博英语模拟试卷1(题后含答案及解析)题型有：1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionThere are a great many careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, in statistical work, and in teaching. But there is an increasing demand for people who are able to take in great area at a glance, people who perhaps do not know too much about any one field. There is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgments. We can call these people “generalists. “And these “generalists”are particularly needed for positions in administration, where it is their job to see that other people do the work, where they have to plan for other people, to organize other people’s work, to begin it and judge it. The specialist understands one field; his concern is with technique and tools. He is a “trained” man; and his educational background is properly technical or professional. The generalist —and especially the administrator —deals with people; his concern is with leadership, with planning, and with direction giving. He is an “educated” man; and the humanities are his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in particular field. Any organization needs both kinds of people, though different organizations need them in different proportions. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly. Your first job may turn out to be the right job for you —but this is pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.1．There is an increasing demand for______.A．all round people in their own fieldsB．people whose job is to organize other people’s workC．generalists whose educational background is either technical or professional D．specialists whose chief concern is to provide administrative guidance to others正确答案：B解析：第一段第三、四句指出，对“一眼即能看到很大范围，可能对任一领域都知之不多；能够看到森林而不是树木，能够做出总体判断”的人的需求在日益增加。

北京航空航天大学考博英语模拟试卷8(题后含答案及解析)题型有：1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionBird wings have a much more complex job to do than the wings of an airplane, for in addition to supporting the bird they must act as its engine, rowing it through the air. Even so the wing outline or a bird conforms to the same aerodynamic principles as those eventually discovered by people when designing airplanes, and if you know how different kinds of aircraft perform, you can predict the flight capabilities of similarly shaped birds. Short, stubby wings enable a tanager and other forest-living to swerve and dodge at speed through the undergrowth, just as they helped the fighter planes of the Second World War to make tight turns and acrobatic maneuvers in a dog-fight. More modern fighters achieve greater speeds by sweeping back their wings while in flight, just as peregrines do when they go into a 130kph dive, swooping to a kill. Championship gliders have long, thin wings so that, having gained height in a thermal up-current they can soar gently down for hours and an albatross, the largest of flying birds, with a similar wing shape and a span of 3 meters, can patrol the ocean for hours in the same way without a single wing beat. Vultures and hawks circle at very slow speeds supported by a thermal and they have the broad rectangular wings that very slow-flying aircraft have. People have not been able to adapt wings to provide hovering flight. That has only been achieved with the whirling, horizontal blades of a helicopter or the downward-pointing engines of a vertical landing jet. Hummingbirds have paralleled even this. They tilt their bodies so that they are almost upright and then beat their wings as fast as 80 times a second producing a similar downdraft of air. So the hummingbird can hover and even fly backwards.1．Which of the following is NOT true according to the passage?A．Bird wings have to support the bird.B．Bird wings must act as the bird’s engine.C．Airplane’s wings must act as the airplane’s engine.D．Similar wing shapes in aircraft and birds produce similar flight capabilities.正确答案：C解析：题目问：根据文章内容，哪项不是真实的?第一段“Bird wings have a much more complex job to do than the wings of an airplane，for in addition to supporting the bird they must act as its engine，rowing it through the air．”通过这句话可知，与飞机的机翼相比，鸟的翅膀的功能更复杂，它能支持鸟体，还是鸟飞翔的引擎。

北京航空航天大学考博英语模拟试卷9(题后含答案及解析)题型有：1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionIn the simplest terms, a market is the place where seller meets buyer to exchange products for money. Traditional markets still function in many parts of the world. Even in the United Sates, during summer months, there are farmers’ markets where direct selling and buying take place between producers and consumers. Most service industries still operate at this market level. Manufacturing industries and most agricultural enterprises are more distant from the consumer. Their products pass through several hands-truckers, warehouse workers, wholesalers, and retailers before reaching the final consumer. Products, or commodities are usually divided into two types: consumer and industrial. Consumer goods are those that are sold to final users, the customers. These goods include food, clothing, automobiles, television sets, appliances, and all those things people go to stores to purchase. Industrial goods are those that are sold to companies or other businesses for use in manufacturing or other purposes. Automobile makers buy many of the parts used to assemble ears. A tire manufacturer buys rubber, synthetic or otherwise, with which to make fires. Eventually these materials will end up in the hands of final users: the owners of the cars. The nature of industrial goods depends on the nature of the goods to be made for final users. The price of industrial goods and raw materials will influence the price of final goods, those that the consumer buys.1．It can be inferred that_____.A．most of the products exchanged at traditional markets are consumer goods B．most of the products bought and sold at traditional markets are industrial goodsC．most farmers lived far away from marketplaces and never sold their products directlyD．most service industries have not yet developed mature markets for their products正确答案：A解析：题目问：从文章内容可以推断出什么?第一段最后一句“Most service industries still operate at this market level．”通过这句话可知，在传统市场里交换的产品大多是消费品。

北京航空航天大学考博英语真题2013年(总分80, 做题时间90分钟)Part Ⅰ Listening Comprehension略Part Ⅱ Reading ComprehensionDirections:There are four passages in this part Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Read the passages carefully and decide on the best choice. Then mark the corresponding letter on the ANSWER SHEET with a single line through the center. Passage 1Printmaking is the generic term for a number of processes, of which woodcut and engraving are two prime examples. Prints are made by pressing a sheet of paper (or other material) against an image-bearing surface to which ink has been applied. When the paper is removed, the image adheres to it, but in reverse.The woodcut had been used in China from the fifth century A.D. for applying patterns to textiles. The process was not introduced into Europe until the fourteenth century, first for textile decoration and then for printing on paper. Woodcuts are created by a relief process; first, the artist takes a block of wood, which has been sawedparallel to the grain, covers it with a white ground, and then draws the image in ink. The background is carved away, leaving the design area slightly raised. The woodblock is inked, and the ink adheres to the raised image. It is then transferred to damp paper either by hand or with a printing press.Engraving, which grew out of the goldsmith"s art, originated in Germany and northern Italy in the middle of the fifteenth century. It is an intaglio process (from Italian intagliare, "to carve"). The image is incised into a highly polished metal plate, usually copper, with a cutting instrument, or burin. The artist inks the plate and wipes it clean so that some ink remains in the incised grooves. An impression is made on damp paper in a printing press, with sufficient pressure-being applied so that the paper picks up the ink.Both woodcut and engraving have distinctive characteristics. Engraving lends itself to subtle modeling and shading through the use of fine lines. Hatching and cross-hatching determine the degree of light and shade in a print. Woodcuts tend to be more linear, with sharper contrasts between light and dark. Printmaking is well suited to the production of multiple images. A set of multiples is called an edition. Both methods can yield several hundred good-quality prints before the original block or plate begins to show signs of wear. Massproduction of prints in the sixteenth century made images available, at a lower cost, to a much broader public than before.SSS_SINGLE_SEL1.What does the passage mainly discuss?A The origins of textile decorationB The characteristics of good-quality printsC Two types\of printmakingD Types of paper used in printmaking该题您未回答:х该问题分值: 1.5答案:C[解析] 本题为主旨题。

2006年北京航空航天大学考博英语试题Part I Listening Comprehension(略)Part II Reading ComprehensionDirections: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Read the passages carefully and decide on the best choice. Then mark the corresponding letter on the ANWER SHEET with a single line through the center.Passage 1Some psychologists maintain that mental acts such as thinking are not performed in the brain alone, but that one's muscles also participate. It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies.You surely are not surprised to be told that you usually listen to music not only with your ears but with your whole body. Few people can listen to music that is more or less familiar without moving their body or, more specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted in direct the orchestra even though he knows there is a competent conductor on the job.Strange as this behavior may be, there is a very good reason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener "feels" himself into the music with more or less pronounced motions of his body.The muscles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less pronounced.21. Some psychologists maintain that thinking is______.A. not a mental processB. more of a physical process than a mental actionC. a process that involves your entire bodyD. a process that involves the muscles as well as the brain22. Few people are able to listen to familiar music without ______.A. moving some part of their bodyB. stopping what they are doing to listenC. directing the orchestra playing itD. wishing that they could conduct music properly23. Body movements are necessary in order for the listener to ______.A. hear the musicB. appreciate the musicC. enjoy the music fullyD. completely understand the music24. According to the selection, muscle participation in the process of thinking is ______.A. deliberateB. obviousC. not readily apparentD. very pronounced25. The best title for this selection is ______.A. An Ear for MusicB. Music AppreciationC. How Muscles Participate in Mental ActsD. A Psychological Definition of the Thinking ProcessPassage 2Laziness is a sin----everybody knows that. We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be moreharmful than that, and it is often caused by more harmful than that, and it is often caused by more complex reasons than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or fear of having their ideas stolen. These people who seem lazy may be paralyzed by a fear of failure that prevents fruitful work. Or other sorts of fantasies may prevent work; some people are so busy planning, sometimes panning great deals or fantastic achievements that they are unable to deal with whatever "lesser" work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating-rescheduling their day.Laziness can actually be helpful. Like procrastinators, some people may look lazy when they are really thinking, planning, contemplating, researching. We should all remember that some great scientific discoveries occurred by chance or while someone was "goofing off". Newton wasn't working in the orchard when the apple hit him and he devised the theory of gravity. All of us would like to have someone "lazy" to build the car to stove we buy, particularly if that "laziness" were cause by the worker's taking time to check each step or his work and to do his job right. And sometimes, being "lazy"----- that is, taking time off for a rest is good for the overworked student or executive. Taking a rest can be particularly helpful to the athlete who is trying too hard or the doctor who's simply working himself overtime too many evenings at the clinic. So be careful when you're tempted to call someone lazy. That person may be thinking, resting, or planning his or her next book.26. The main idea of this passage is that ______.A. laziness is a moral sinB. there are advantages and disadvantages in being lazyC. laziness is the sign of deep-seated emotional problemsD. lazy people do more careful work27. The passage states that ______.A. laziness is a diseaseB. some people appear lazy because they are insecureC. laziness is more beneficial than harmfulD. a good definition of laziness is emotional illness28. Which of the following conclusion does the passage support? ______A. The word laziness is sometimes applied incorrectly.B. Most of the time laziness is a virtue.C. Most assembly line workers are lazy.D. Most insecure people are lazy.29. The final paragraph is ______.a. gloomy B. humorous C. serious D. ironical30. "Goofing off" as used in paragraph 2 probably means ______.A. wasting timeB. sleepingC. workingD. chatting with friendsPassage 3The idea of humanoid robots is not new. They have been part of the imaginative landscape ever since Karl Capek, a Czech writer, first dreamed them up for his 1921 play "Rossum's Universal Robots". (The word "robot" comes from the Czeeh word for drudgery, robota.) Since then, Hollywood has produced countless variations on the theme, from the sultry False Maria in Fritz Lang's silent masterpiece "metropolis" to the withering C-3PO in "Star Wars" and the ruthless assassin of "Terminator". Humanoid robots have walked into our collective subconscious, coloring our views of the future.But now Japan's industrial giants are spending billions of yen to make such robots a reality. Their new humanoids represent impressive feats of engineering: when Honda introduced Asimo, a four-foot robot that had been in development for some 15 years, it walked so fluidly that its white, articulated exterior seemed toconceal a human. Honda continues to make the machine faster, friendlier and more agile. Last October, when Asimo was inducted into the Robot Hall of Fame in Pittsburgh, it walked on the stage and accepted its own plaque.At two and a half feet tall, Sony’s QRIO is smaller and more toy-like than Asimo. It walks, understands a small number of voice commands, and can navigate on its own. It is falls over, it gets up and resumes where it left off. It can even connect wirelessly to the internet and broadcast what its camera eyes can see. In 2003, Sony demonstrated an upgraded QRIO that could run. Honda responded last December with a version of Asimo that runs at twice the speed.In 2004, Toyota joined the fray with its own family of robots, called Partner, one of which is a four-foot humanoid that plays the trumpet. Its fingers work the instrument’s valves, and it has mechanical lungs and artificial lips. Toyota hopes to offer a commercial version of the robot by 2010. This month, 50 Partner robots will act as guides at Expo 2005 in Aichi, Japan.Despite their sudden proliferation, however, humanoids are still a mechanical minority. Most of the world's robots are faceless, footless and mute. They are bolted to the floors of factories, stamping out car parts or welding pieces of metal, making more machines. According to the United Nations, business orders for industrial robots jumped 18% in the first half of 2004. They may soon be outnumbered by domestic robots, such as self-navigating vacuum cleaners, lawn mowers, and window-washers, which are selling fast. But neither industrial nor domestic robots are humanoid.31. In paragraph 1 the author introduces this topic by relating ______.A. the idea of humanoid robotsB. Karl Capek's creation of robotsC. Hollywood's production of robot filmsD. the origin of and popular movies about robots32. According to the author's description, Asimo ______.A. is a four-legged robotB. seems more like a human being than a machine in actionC. seems more like a machine than a human being in actionD. is in a sort of animal form33. Sony’s QRIO could perform all the following tasks EXCEPT ______.A. walking everywhere freelyB. understanding some words uttered by peopleC. finding its wayD. continuing walking after it stumbles34. From the passage we may infer that Toyota’s Partner ______.A. is much better than any other robotsB. is no more than a mechanic deviceC. may be put into mass productionD. may speak like man35. Judging from the context, this passage is probably written ______.A. in 2004B. in 2005C. between 2003~2004D. between 2004~2005Passage 4Ocean water plays an indispensable role in supporting life. The great ocean basins hold bout 300 million cubic miles of water. From this vast amount, bout 80,000 cubic miles of water are sucking into the atmosphere each year by evaporation and returned by precipitation and drainage to the ocean. More than 24,000 cubic miles of rain descend annually upon the continents. This vast amount is required to replenish the lakes and streams, springs and water tables on which all flora and fauna are dependent. Thus, the hydrosphere permitsorganic existence.The hydrosphere has strange characteristics because water has properties unlike those of any other liquid. One anomaly is that water upon freezing expands by about 9 percent, whereas most liquids contract on cooling. For this reason, ice floats on water bodies instead of sinking to the bottom. If the ice sank, the hydrosphere would soon be frozen solidly, except for a thin layer of surface melt water during the summer season. Thus, all aquatic life would be destroyed and the interchange of warm and cold currents, which moderates climate, would be notably absent.Another outstanding characteristic of water is that it has a heat capacity which is the highest of all liquids and solids except ammonia. This characteristic enables the oceans to absorb and sore vast quantities of heat, thereby often preventing climate extremes. In addition, water dissolves more substances than any other liquid. It is this characteristic which helps make oceans a great storehouse for minerals which have been washed down from the continents. In several areas of the world these minerals are being commercially exploited. Solar evaporation of salt is widely practiced, potash is extracted from the Dead Sea, and Magnesium is produced from seawater along the American Gulf Coast.36. A characteristic of water NOT mentioned in this passage is that water ______.A. expands on freezingB. is a great solventC. is like ammoniaD. has a very high heat capacity37. From this passage, we may conclude that ______.A. ocean and land masses are equalB. ocean masses are smaller than land massesC. it is difficult to get fresh water from the oceanD. none of the above is correct38. By “hydrosphere” the author means ______.A. the moisture in the airB. the part of the earth covered by waterC. the Milky WayD. the frozen waters of the earth39. Fish can survive in the oceans because ______.A. there are currents in the oceanB. ice floatsC. evaporation and condensation create a water cycleD. water absorbs heat40. “Anomaly”, as used in the second paragraph, means ______.A. state of being anonymousB. abnormalityC. characteristicD. propertyPart III Vocabulary (10 points)Directions: In this part, there are 20 sentences with four choices below each sentence.

北京航空航天大学考博英语模拟真题及其解析“I want to criticize the social system,and to show it at work,at its most intense.”Virginia Woolf’s provocative statement abouther intentions in writing Mrs.Dalloway has regularly been ignoredby the critics,since it highlights an aspect of her literaryinterests very different from the traditional picture of the Geng duoyuan xiao wan zheng kao bo ying yu zhen ti ji qi jie xi qing lian xiquan guo mian fei zi xun dian hua:si ling ling liu liu ba liu jiuqi ba,huo jia zi xun qq:qi qi er liu qi ba wu san qi“poetic”novelistconcerned with examining states of reverie and vision and withfollowing the intricate pathways of individual consciousness.ButVirginia Woolf was a realistic as well as a poetic novelist,a satiristand social critic as well as a visionary:literary critics’cavalierdismissal of Woolf’s social vision will not withstand scrutiny.In her novels,Woolf is deeply engaged by the questions of howindividuals are shaped(or deformed)by their social environments,how historical forces impinge on people’s lives,how class,wealth,and gender help to determine people’s fates.Most of her novels arerooted in a realistically rendered social setting and in a precisehistorical time.Woolf’s focus on society has not been generally recognizedbecause of her intense antipathy to propaganda in art.The picturesof reformers in her novels are usually satiric or sharply critical.Even when Woolf is fundamentally sympathetic to their causes,sheportrays people anxious to reform their society and possessed of amessage or program as arrogant or dishonest,unaware of how their political ideas serve their own psychological needs.(Her Writer’s Diary notes:“the only honest people are the artists,”whereas “these social reformers and philanthropists…harbor…discreditable desires under the disguise of loving their kind…”) Woolf detested what she called“preaching”in fiction,too,and criticized novelist wrence(among others)for working by this method.Woolf’s own social criticism is expressed in the language of observation rather than in direct commentary,since for her,fiction is a contemplative,not an active art.She describes phenomena and provides materials for a judgment about society and social issues; it is the reader’s work to put the observations together and understand the coherent point of view behind them.As a moralist, Woolf works by indirection,subtly undermining officially accepted mores,mocking,suggesting,calling into question,rather than asserting,advocating,bearing witness:hers is the satirist’s art.Woolf’s literary models were acute social observers like Chekhov and Chaucer.As she put it in The Common Reader,“It is safe to say that not a single law has been framed or one stone set upon another because of anything Chaucer said or wrote;and yet,as we read him, we are absorbing morality at every pore.”Like Chaucer,Woolf chose to understand as well as to judge,to know her society root and branch —a decision crucial in order to produce art rather than polemic.1.Which of the following would be the most appropriate title for the text?[A]Poetry and Satire as Influences on the Novels of Virginia Woolf.[B]Virginia Woolf:Critic and Commentator on theTwentieth-Century Novel.[C]Trends in Contemporary Reform Movements as a Key to Understanding Virginia Woolf’s Novels.[D]Virginia Woolf’s Novels:Critical Reflections on the Individual and on Society.2.In the first paragraph of the text,the author’s attitude toward the literary critics mentioned can best be described as[A]disparaging.[B]ironic.[C]facetious.[D]skeptical but resigned.3.It can be inferred from the text that Woolf chose Chaucer asa literary example because she believed that[A]Chaucer was the first English author to focus on society as a whole as well as on individual characters.[B]Chaucer was an honest and forthright author,whereas novelists like wrence did not sincerely wish to change society.[C]Chaucer was more concerned with understanding his societythan with calling its accepted mores into question.[D]Chaucer’s writing was greatly,if subtly,effective in influencing the moral attitudes of his readers.4.It can be inferred from the text that the most probable reason Woolf realistically described the social setting in the majority of her novels was that she[A]was aware that contemporary literary critics considered the novel to be the most realistic of literary genres.[B]was interested in the effect of a person’s social milieu on his or her character and actions.[C]needed to be as attentive to detail as possible in her novels in order to support the arguments she advanced in them.[D]wanted to show that a painstaking fidelity in the representation of reality did not in any way hamper the artist.5.Which of the following phrases best expresses the sense of the word“contemplative”as it is used in line2,paragraph4of the text?[A]Gradually elucidating the rational structures underlying accepted mores.[B]Reflecting on issues in society without prejudice or emotional commitment.[C]Avoiding the aggressive assertion of the author’s perspective to the exclusion of the reader’s judgment.[D]Conveying a broad view of society as a whole rather thanfocusing on an isolated individual consciousness.[答案与考点解析]1.【答案】D【考点解析】这是一道中心主旨题。

北京航空航天大学考博英语真题2014年(总分100, 做题时间90分钟)Ⅰ. Reading ComprehensionDirections:In this section, there are four texts. After each text, there are five questions marked A, B, C and D. Mark your answers on ANSWER SHEET 1.Text OneA controversy erupted in the **munity in early 1998 over the use of DNA (deoxyribonucleic acid) fingerprinting in criminalinvestigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it isin the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to prove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in 1998 stemmed from a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate. In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K. Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the Federal Bureau ofInvestigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples from various ethnic groupsin an attempt to resolve some of these questions. And, in April, aNational Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.SSS_SINGLE_SEL1.Before DNA fingerprinting is used, suspects ______.A would have to leave their fingerprints for further investigationsB would have to submit evidence for their innocenceC could easily escape conviction of guiltD could be convicted of guilt as well该题您未回答:х该问题分值: 1.5答案:C[解析] 本题为推理题。

北京航空航天大学考博英语真题及解析(总分：100.00，做题时间：180分钟)Ⅰ Reading ComprehensionTest One(总题数：1，分数：7.50)Sixty days walking over ice and snow in temperature as low as -45℃, with nothing to keep you company except the occasional polar "bear". This is no small achievement. Only a few people have ever walked to the North Pole unassisted, and if Christina Franco succeeds, she will have earned a place in the history books and met one of the few remaining challenges of exploration left to women.Her 480-mile journey will begin in northern Canada, dragging a sledge that weighs as much as she does. At the end of each day's walking or skiing, she will pitch her tent in subzero temperatures, get into a sleeping bag filled with ice, and attempt to sleep to the unsettling background sounds of howling wind and cracking ice, which may or may not signal the approach of one of those polar bears. "I'll carry a pistol to scare any bears away," says Franco, 42. "The bears that far north won't have had contact with humans, fortunately, so they won't associate me with food, but they will be curious and that's dangerous. If it uses a paw to see what you are, it could damage your tent—or your arm. I imagine I'll have quite a few sleepless nights."Many of the early polar explorers suffered from disease and injuries, and while modem technology (lightweight materials, satellite phones, places on stand-by to carry out rescue missions) has lessened the dangers, it can never make such an inhospitable landscape anything approaching safe. It can take just five minutes for any uncovered skin to become frostbittenand, once the sun has risen, Franco will only be able to remove her sunglasses inside her tent, otherwise the intensity of the sunlight reflecting off the snow would cause snow blindness. Just to heighten the danger, the cold will slow down her brain functions, so it will be more difficult to make split-second decisions in the event of a sudden crisis.She will use about 8,000 calories a day, losing nearly half a kilogram every 24 hours. "The problem is that the human body can only take on about 5,500 calories a day," she says. "So you have to fatten up before you set off or you'll run out of energy." Franco is currently trying to put on 19 kilos. She may complain about not fitting into any of her dresses, but when Franco weighs herself in front of me and finds she's lost one kilo rather than gained two, as she'd expected, she's very upset. "I hope my scales are wrong because, if not, I've lost weight," she says, reaching for one of many bars of chocolate lying around her kitchen.1. What does the writer say about the history of exploration? ______（分数：7.50）A.Walking to the North Pole used to be considered easier than other journeys.B.No woman has ever completed the journey to the geographic North Pole.C.Female explorers have already done most of the world's difficult journeys. √D.Franco is already an important historical figure for her previous journeys.解析：根据第一段中的“Only a few people have ever walked to the North Pole unassisted, and if Christina Franco succeeds, she will have earned a place in the history books and met one of the few remaining challenges of exploration left to women.”可知，只有少数人曾独自走到北极，如果克里斯蒂娜·佛朗哥成功了，她将在史书中占有一席之地，完成为女性留下的尚未完成的为数不多的探险挑战之一。

WritingReading ComprehensionTo call someone bird-brained in English means you think that person is silly or stupid. But will this description soon disappear from use in the light of recent research? It seems the English may have been unfair in association bird’s brains with stupidity. In an attempt to find out how different creatures see the world, psychologists at Brown University in the USA have been comparing the behaviour of birds and humans. One experiment has involved teaching pigeons to recognize letters of the English alphabet. The birds study in “classrooms”, which are boxes equipped with a computer. After about four days of studying a particular letter, the pigeon has to pick out that letter from several displayed on the computer screen. Three male pigeons have learnt to distinguish all twenty-six letters of the alphabet in this way. A computer record of the birds’four-month study period has shown surprising similarities between the pigeons’and human performance. Pigeons and people find the same letters easy, or hard, to tell apart. For example, 92 percent of the time the pigeons could tell the letter D from the letter Z. But when faced with U and V (often confused by English children), the pigeons were right only 34 percent of the time. The results of the experiments so far have led psychologists to conclude that pigeons and humans observe things in similar ways. This suggests that there is something fundamental about the recognition process. If scientists could only discover just what this recognition process is it could be very useful for computer designers. The disadvantage of a present computer is that it can only do what a human being has programmed it to do and the programmer must give the computer precise, logical instructions. Maybe in the future, though, computers will be able to think like human beings.1．The writer suggests that the expression “bird-brained” might be out of use soon because it is______.A．sillyB．impoliteC．unnecessaryD．inappropriate正确答案：D解析：根据文中第一段的“To call someone bird-brained in English means you think that person is silly or stupid．But will this description soon disappear from use in the light of recent research?It seems the English may have been unfair in associationbird’s brains with stupidity．”可知，在英语中，如果称某人的大脑像鸟脑袋一般，意思就是这个人没有头脑或非常愚蠢。

2022年考研考博-考博英语-北京航空航天大学考试全真模拟易错、难点剖析B卷（带答案）一.综合题(共15题)1.单选题In recent years, teachers of introductory courses in Asian American studies have been facing a dilemma nonexistent a few decades ago, when hardly any texts in that field were available. Today, excellent anthologies （文选）and other introductory texts exist, and books on individual Asian Ameri- cans are published almost weekly. Even professors who are experts in the field find it difficult to de-cide which of these to assign to students ； non-experts who teach in related areas and are looking for writings for and by Asian American to include in survey courses are in an even worse position.A complicating factor has been the continuing lack of specialized one-volume reference works on Asian Americans, such as biographical dictionaries or desktop encyclopedias. Such works would ena-ble students taking Asian American studies courses （ and professors in related fields） to look up basic information on Asian American individuals, institutions, history, and culture without having to wade through （费力地阅读冗长或艰深的材料）mountains of primary source material. In addition, givensuch works, Asian American studies professors might feel more free to include more challenging Asian American material in their introductory reading lists, since good reference works allow students to ac-quire on their own the background information necessary to interpret difficult or unfamiliar material.1.The author is primarily concerned with（）.2.The “dilemma” (Line 2，Para. 1) can best be characterized as being caused by the necessity to make a choice when faced with a（）3.Biographical dictionaries and desktop encyclopedias are（） .4.Which of the following is implied about the introductory courses in Asian American studiesa few decades ago?5.According to the passage, the existence of good one-volume reference works about Asian Ameri-cans could result in（）问题1选项A.responding to a criticismB.describing a course of studyC.discussing a problemD.evaluating a past course of action 问题2选项ck of acceptable alternativesck of strict standards for evaluating alternativesC.preponderance of bad alternatives as compared to goodD.multitude of different alternatives问题3选项A.primary source materialsB.introductory textsC.excellent anthologiesD.reference materials问题4选项A.The range of different textbooks that could be assigned for such was extremely limited.B.The texts assigned as readings in such courses were often not very challenging for students.C.Students often complained about the texts assigned to them, in such courses.D.Such courses were offered only at schools whose libraries were rich in primary sources.问题5选项A.increased agreement among professors of Asian American studies regarding the quality of the sources available in their fieldB.an increase in the number of students sighing up for introductory courses in AsianAmerican studiesC.increased accuracy in writings that concern Asian American history and cultureD.the inclusion of a wider range of Asian American material in introductory reading lists in Asi-an American studies【答案】第1题:C第2题:D第3题:D第4题:A第5题:D【解析】1.主旨题。

WritingReading ComprehensionUnless 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 sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands whose orbits put them on a collision course with Earth. Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By 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 weapons. But 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 400, 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 from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.1．What does the passage say about asteroids and meteoroids?A．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.正确答案：B解析：依据文章第二段第1行可以判断出两者性质相似只是体积不同，排除A项；文中并无两者数量上的比较，排除C项；也没有涉及D项的内容。
