江苏省2017年普通高校专转本选拔考试Part 1 Reading Comprehension 共20小题;每小题2分;共40分Directions There are 4 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.You should decide on the best choice and mark your answer by blackening the corresponding letter on Answer Sheet.Passage OneQuestions 1 to 5 are based on the following passageWe use both words and gestures to express our feelings;but the problem is that these words and gestures can be understood in different waysIt is true that a smile means the same thing in any language;So does laughter or crying.There are also a number of striking similarities in the way different animals show the same feelings .Dogs; tigers and humans;for example; often show their teeth when they are angry.This is probably because they are born with those behavior patternsFear is another emotion that is shown in much the same way all over the world.In Chinese and English literature; a phrase like “he went pale and begin to tremble”suggests that the man is either very afraid or deep shocked; However;”he opened his eyes wide”is used to suggest anger in Chinese whereas in English it means surprise In Chinese surprise can be described in a phrase like “they stretched out their tongues”Sticking out your tongue in English is an insulting gesture or expresses strong dislikeEven in the same culture; people differ in ability to understand and express feelings;Experiments in America have shown that women are usually better than men at recognizing fear;anger;love and happiness on people’s faces;Other studies show that older people usually find it easier to recognize or understand body language than younger people do.1.According to the passage;——BA.We can hardly understand what people’s gestures meanB.words and gestures may have different meaning in different culturesC.words can be better understood by older peopleD.gestures can be understood by most of the people while words can not2.People’s facial expressions may be misunderstood because——BA people of different ages may have different understandingB people have different culturesC people of different sexes may understand a gesture differentlyD people of different countries speak different languagesA.3 .Even in the same culture.people ——AB.have different abilities to understand and express feelingsB.have exactly the same understanding of somethingC.never fail to understand each otherD.are equally intelligent4.From this passage; we can conclude ——C5.A words are used as frequently as gesturesB words are often difficult to understandC words and gestures are both used in expressing feelingsD gestures are more efficiently used than words5.The best title for this passage may be ——BA.Words and FeelingsB.Words;Gestures and FeelingsC.Gestures and FeelingsD.Culture and UnderstandingPassage TowQuestions 6 to 10 are based on the following passageThe English policeman has several nicknames but the most frequently used are"copper" and "bobby" the first name comes from the verb "to cop".which is also slang.meaning to take or to capture".and the second comes from the first name of Sir Robert Peel; the nineteenth-century politician; who was the of the police force as we know it today.An early nickname for the policeman was "peeler" but this one has died out.Whatever we may call them;the general opinion of the police seems to be a favorable one; except; of course; among the criminal part of the community where the police are given more derogatory nicknames which originated in America; such as "fuzz" or "pig".Visitors to England seem to be very impressed by the English police.It has.In fact; become a standing joke that the Visitor to Britain; when asked tar his views of the country.will always say; at some point or other; "I think your policemen are wonderful."Well;the British bobby may not always be wonderful but he is usually a very friendly and helpful sort of character.A music-hall song of some years ago was called "If You Want To Know The Time; Ask A Policeman".Nowadays.most people own watches but they still seem to find plenty of other questions to ask the policemen. In London; the policemen spend so much of their time directing visitors about the city that one wonders how they ever find time to do anything else.Two things are Immediately noticeable to the stranger; when he sees an English policeman for the first time.The first is that he does not carry a pistol and the second is that he wears a very distinctive of headgear.the policeman's helmet ;His helmet; together which his height;enables an English policeman to he seen from a considerable distance; a fact that is not without its usefulness.From time to time it is suggested that the policeman should be given a pistol and that his helmetshould be taken from him; but both these suggestions are resisted by given and that his helmet should be taken from him ;but both suggestions are resisted by the majority of the public and the police themselves.6.Nowadays British people call the policeman ——CA.pigB.peelerC.BobbyD.Fuzz7.Which of the following statements is TRUE BA.There are fewer criminals America than tn Britain.B.The English police usually leave a deep impression on visitors.C.The English bobby is friendly but not helpful.D.The English police enjoy having pistols.8.If you see an English policeman for the first time.you will probably notice at once that ——CA.he often tells people timeB.he is usually very helpfulC.he has a helmet on the headD.he wears special clothes9.That an English policemen can be seen from some distance is ——DA.standing jokeB.Of no helpC.Strange and funnyD.Of some help10.Visitors praise the English police because ——AA.they are polite and helpfulB.they obey ordersC.they often given thanksD.they are armed with modem equipmentPassage ThreeQuestions 11 to 15 are based on the following passage.It is difficult to imagine what life would be like without memory.The meanings of thousands of everyday perceptions the bases for the decisions we make; and the roots of our habits and skills are to he found in our past experiences;which are brought into the present by memory.Memory can be defined as the capacity to keep information available for later use.It not only includes "remembering" things like arithmetic or historical facts but also involves any change in the way an animal typically behaves.Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile.Memory is also involved when a six-year-old child learns to swing a baseball bat.Memory exists not only in humans and animals but also in some physical objects and puters.for example; contain devices from storing data for later use.It is interesting to compare the memory-storage capacity of a computer with that of a human being.The instant-access memory of a large computer may hold up to 100;000" words" -ready for instant use.An average American teenager probably recognizes the meaning of about 100;000 words of English.However; this is but a fraction of the total amount of information which the teenager has stored.Consider.tar example- the number of faces and places that the teenager can recognize on sight.11.The use of words is the bass of the advanced problem-solving intelligence of human beings.A large part of a person's memory is in terms of words and combinations of words.12.According to the passage; memory is considered to be ——BA.the basis for decision making and problem solvingB.the ability to store information for future useC.an intelligence typically possessed by human beings13.D.the data mainly consisting of words and combinations of words14.The comparison between the memory capacity of a large computer and that of a human being shows that——Cputer's memory has a little bigger capacity than a teenager'sputer's memory capacity is much smaller than an adult human being'sputer's memory's capacity is much smaller even than a teenager'sputer's memory's capacity is the same as a teenager's13.1t is implied in the passage that ——CA.only human beings have problem-solving intelligenceB a person's memory is different from a computer's in every respectC.animals can solve very simple problemsD animals solve problems by instincts rather than intelligence14.The phrase “in terms of”in the last sentence can be best replaced by——BA.in connection withB.expressed byC.consistingD.by means of15.The main idea of the passage is——BA.What life would be like without memoryB.Memory is of vital importance to lifeC.How a person’s memory different from an animal’s or a computer’sD.What memory carriesPassage fourQuestions 16 to 20 are based on the following passageClearly if we are to participate in the society in which we live; we must communicate with other people.A great deal of communicating is performed on a person-to-person basis by the simple means of speech.If we travel inbuses; buy things in shops; or eat in restaurants; we are likely to have conversations where we give information or opinions; receive news or comment; and very likely to have our views challenged by other members of society.Face to face contact is by no means the only form of communication and during the last two hundred years the art of mass communication has become one of the dominating factors of contemporary society.Two things; above others; have caused the enormous growth of the communication industry.Firstly; inventiveness has led to advanced imprinting; telecommunications photography; radio and television.Secondly; speed has revolutionized the transmission and reception of communications so that local news often takes a back seat to national news; which itself is often almost eclipsed 黯然失色by international news.No longer is the possession of information confined to只限于a privileged minority.In the last century the wealthy man with his own library was indeed fortunate; but today there are public libraries.For years ago people used to flock to the cinema; but now far more people sit at home and turn on the TV to watch a programme that is being channeled into millions of homes.Communication is no longer merely concerned with the transmission of information.The modem communication industry influences the way people live in society and broadens their horizons by allowing access to information; education and entertainment.The printing; broadcasting and advertising industries are all involved with informing; educating and entertaining.Although a great deal of the material communicated by the mass media is very valuable to the individual and to the society of which he is part; the vast modem network of communications is open to abuse.However; the mass media are with us for better; for worse; and there is no turning back.16.The first paragraph the writer emphasizes the ——of face-to-face contact in social setting. DA. natureB. limitationC. creativityD. Usefulness17.The development of the communication industry in contemporary society results from ——BA.the advances and revolutionsB.the inventiveness and speedC.the art of mass communicationD.the advances and speed18.It is implied in the passage that —— C .A. local news used to be the only source of informationB. local news still takes a significant placeC. national news is becoming more popularD. international news is the fastest transmitted news19.Which of the following statements is NOT true AA. Public libraries have replaced the private libraries.B. To possess information used to be a privilegeC. Communication means more than transmission.D. Communication influences ways of life and thinking.20.It can be inferred from the last paragraph we can infer that the writer is ___A___.A.concerned about the wrong use of the mass mediaB.Happy about the flexible change in the mass mediaC.Pessimistic about the future of the mass mediaD.Indifferent to the harmful influence of the mass medPart II Vocabulary and Structure 共40小题;每小题1分;共40分Directions : there are 40 incomplete sentences in this part For each sentence there are 4 choices marked A;

2024年江苏省一般高等学校“专转本”统一考试高校英语第I卷(共100分)Part I Reading Comprehension (共40分)Passage oneUnder proper conditions, sound waves will be reflected from a hillside or other such obstruction. Sound travels at the rate of about one-fifth of mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel o the hill and back. Thus, by timing the interval between a sound and its reflection (the echo), you can estimate the distance to an obstruction.During word war 2 the British used a practical application of this principle to detect German planes on their way to bomb London long before the enemy was near the target. They used radio waves instead of sound waves, since radio waves can penetrate fog and clouds. The outnumbered Royal Air Force (RAF) always seemed to the puzzled Germans to be lying in wait at the right time and never to be surprised. It was radio echoes more than anything else that won the Battle of Britain.Since the radio waves were used to tell the direction in which to send the RAF planes and the distance to send them (their range of flight, in other words), the device was called radio directing and ranging, and from the initials the word radar was coined. (files come from )1. Sound waves reflected from a hill can be used to estimate the.A. heigt of the hillB. speed of soundC. distance to the hillD. intensite of sound2. Practical applications of this principles resulted in.A. New electronic instruments for planesB. A radio directing and ranging deviceC. New radio sets for RAF bombersD. An electronic detecting device3. Radar enabled the English to.A. Detect German planes on their way to LondonB. Direct the outnumbered RAF planes effectivelyC. Confuse German bomber pilotsD. Both A and B4.It can be inferred from the passage thatA. Light waves could be used in a device similar to radarB. Radar was a practical application of a well-known principleC. Radar greatly increased the effectiveness of the Royal Air ForceD. Sound waves are reflected from a hillside under all conditions5. The author of this passage probably intended to explainA. Exactly how radar worksB. Why the British used radio waves in their deviceC. How radar (work and device) came to beD. How radar helped the British win the Battle of BritainPassage TwoIn general, the ancient Romans were a practical people. They cared less about philosophy and pure mathematics than did the Greeks. The Romans were the best of the ancient engineers and architects. They were brilliant students of Greek geometry and trigonometry (三角学) , and they applied their knowledge to the construction of fine bridges, roads, aqueducts (渠道) , and public buildings.They knew about the smelting of iron ore, but they used the iron they produced mainly for spears, swords, and shields, rather than for building construction.While the Romans accomplished practical wonders, they did very little theoretical scientific thinking. Because of their frequent wars, many of their inventions were no more than improvements in the design of Greek weapons with which they were familiar.There are two reasons for the Romans neglect of philosophy and pure mathematics. First, they were apparently too busy conquering nearby nations and forming them into a rapidly growing empire to waste time on abstract thinking. Secondly, they were handicapped (阻碍) by the rigidity of their numerical system. (Try to multiply XI by LVII orto divide CXLIII by IX; it simply cannot be done with pencil and paper.) The Romans did all of their arithmetic on an abacus, the ancient counterpart of the modern computing machine. Their number system discouraged the study of pure mathematics.6. The author calls the Romans “practical” because theyA. Cared little about philosophyB. Applied their knowledge to constructionC. Saw the necessity for developing theoretical scienceD. Studied the past and learned from it7.The ancient Romans did not concern themselves withA. Theoretical or abstract thoughtB. applied mathematicsC. StudyingD. either A or C8.In construction, the Romans made extensive use ofA. Iron oreB. peometry and trigonometryC. StudyingD. both B and C9.Many Romans inventions were based on Greek weapons because theA. Greeks had superior weaponsBromines were involved in frequent warsC. Romans were not familiar with many types of weaponsD. Greek proved himself or herself inspired inventor10.The author of this passage probably wanted to explain whyA. He considers the Romans a practical peopleB. Roman were involved in frequent warsC. Theoretical thinking is necessary fir the growth of a nationD. The Romans contributed little to philosophical thoughtPassage ThreeProfessor Barry Wellman if University of Toronto in Canada has invented a term to describe the way many North Americans interacts these days. The term to have opposite meanings. How can we be individuals and be networked at the same time? You need other people for networks.Here is what Professor Wellman means. Before the invention of the Internet ande-mail, our social networks involved live interactions with relatives, neighbors, and colleagues at work. Some of the interaction was by phone, but it was still voice, person to person, in real time.A recent research study by the Pew Internet and Americans Life Project showed that for a lot of people, electronic interaction through the coputer has replaced this person-to-person interaction. However, a lot of people interviewed for the Pew study say that’s a good thing. Why?In the past, many people were worried that the Internet isolated us and caused us to spend too much time in the imaginary world of the computer. But the Pew study discovered that the opposite is true. The Internet connects us with MORE real people than expected-helpful-people who can give advice on careers, medical problems, raising children, and choosing a school or college. About 60 million American told Pew that the Internet plays an important role in helping them major life decisions.Thanks to the computer. “networked individuals” are able to be alone and together with other people-at the same time!11. the pew study was conducted inA. the United StatesB. CanadaC. the U.S. and CanadaD. Europe12. in the article, a network is a group of connectedA. radio or TV stationsB. peopleC. computersD. roads13. before the invention of the Internet, our connections with people tool place mainlyA. in personB. by phoneC. by letterD. by e-mail14. Which of the following has happened since the invention of the Internet and email?A. people are talking on the phone more than ever.B. Interaction through the computer has replaced a lot of person to person interaction.C. Americans are turning into hermits.D. Sixty million Americans have bought computers.15. Which of the following was NOT one of the discoveries of Pew study?A. The Internet has put us in touch with more people than expected.B. People use the Internet to get advice on careers, medical problems, and otherquestions.C. For many Americans, the Internet plays an important role in helping them makeimportant decisions.D. “Internet addiction” is a growing problem among people who use computers. Passage four(非英语类学生必做)Summers with father were always enjoyable. Swimming, hiking, boating, fishing-the days were not long enough to contain all of activities. There never seemed to be enough time to go to church, which disturbed some friends and relations. Accused of neglecting this part of our education, my father instituted a summer school for my brother and me. However, his summer course included ancient history, which Papa felt our schools neglected, and navigation, in which we first had a formal examination in the dining room, part of which consisted of tying several knots in a given time limit. Then we were each separately sent on what was grandly referred to as a cruise in my father’s 18-foot knockabout, spending the night on board, and loaded down, according to formally plot our course, using the tide table, even though our goal was an island I could see quite clearly across the water in the distance.16. What was the original reason for holding the summer school?A. The father wanted the children to learn more about religion.B. The children got poor grades in their regular school.C. The regular school teachers neglected the children.D. Friends and relatives thought the children should learn religion.17. The purpose of the cruise mentioned in the passage was toA. have funB. test the author for completing summer schoolC. reward the author for completing summer schoolD. get to the island18. Why did the author have to plot the summer of her cruise?A. She had to demonstrate her to do so.B. She was afraid of getting lost.C. The coast was dangerous.D. The tides were strong.19.

Apparently a knockabout isA. a seaman’s knotB. a cruiseC. an islandD. a boat(英语类学生必做)The three main types of secondary education in the United States have been provided by the Latin grammar school, the academy, and the public high school. The first of these was a colonial institution. It began in New England with the establishment in 1635 of the Boston Free Latin School. The curriculum consisted mainly of the classical languages, and the purpose of this kind of school was the preparation of boys for college, where most of them would be fitted for the ministry.The academy began in the early 1750’s with Benjamin Franklin’s school in Philadelphia, which later became the University of Pennsylvania. It extended generally to about the middle of the nineteenth century, except in the southern states where the public high school was late in developing and where the academy continued a principal means of secondary education even after 2900. the academy was open to girls as well as to boys, and it provided a wider curriculum than the Latin grammar school had furnished. It was designed not only as a wider curriculum than the Latin grammar school had furnished. It was designed not only as a preparation for college but also for practical life in commercial and business activities. Although its wide educational values were evident and are recognized as important contributions to secondary education in this country, the academy was never considered a public institution as the public high school has come to be.The public high school had its origin in Massachusetts in 1821 when the EnglandClassicalSchool was established in Boston. In 1827, that state enacted the first state-wide public high-school law in the United States. By 1840, there were perhaps a dozen public high schools in Massachusetts and many in other eastern states; by 1850, they were also to be found in many other states.Just as the curriculum of the academy grew out of that of the Latin grammar school, so the curriculum of the public high school developed out of the academy. The public high school in the United States is a rejection of the aristocratic (贵族) and selective principle of the European educational tradition. Since 1890, enrollments in secondary schools, mainly public high schools, have practically doubled in this country every ten years.16. According to the author, the main types of secondary education in the United States have been provided byA.

From the airport, my friend and I 66 a taxi to my hotel. On the way, I saw the skyline of Manhattan for the first time and I stared in 67 at the famous Word Trade Centre, the tallest building in the word. My friend helped me 68 at the hotel and then left because he had to go 69 to work. He promised to return the next day.Shortly after he left, I went to a 70 near the hotel to get something to eat. As I cou ldn't speak 71 of english, I couldn’t tell the 72 what I wanted. I was very upset and started to make some gestures, but the waiter didn’t 73 me.

But how much sleep do we actually need?For most of us, eight hours seems to be about the right amount. Yet we know that there are many people who get 61 perfectly with less sleep, and some who may need 62 . A great deal depends on the 63 we live.

There is a deep sleep and shallow sleep. In a shallow sleep our body does not get the same kind of rest it gets in a 67 sleep, 68 after eight hours of a shallow sleep we may still feel tired.

Once, during the night before an important battle, he remained 71 longer than anyone else. 72 he wrapped himself in a cloak and 73 down on the earth. He slept so 74 that his generals had to wake him three times for him to give the 75 to atack!Normally when we sleep, our “sleep center” blocks off nerves so that 76 our brain and body go to sleep. 77 prevents us from wanting to do anything, and the other 78our internal organs and limbs go to sleep. 79 sometmes only one goes to sleep and the other does not.
