1、考博英语-572 及答案解析(总分：100.00，做题时间：90 分钟)一、Part Reading Compr(总题数：0，分数：0.00)二、Passage 1(总题数：1，分数：5.00)All animals must rest, but do they really sleep as we know it? The answer to this question seems obvious. If an animal regularly stops its activities and stays quiet and unmovingif it looks as though it

2、is sleepingthen why not simply assume that it is in fact sleeping? But how can observers be sure that an animal is sleeping?They can watch the animal and notice whether its eyes are open or closed, whether it is active or lying quietly, and whether it responds to light or sound. These factors are im

3、portant clues, but they often are not enough. Horses and cows, for example, rarely close their eyes, and fish and snakes cannot close them. Yet this does not necessarily mean that they do not sleep. Have you ever seen a cat dozing with an eye partly open? Even humans have occasionally been observed

4、to sleep with one or both eyes partially open. Animals do not necessarily lie down to sleep either. Elephants, for example, often sleep standing up, with their tusks resting in the fork of a tree. Finally, while “sleeping“ animals often seem unaware of changes in the sounds and light and other stimu

5、li around them, that does not really prove they are sleeping either.Observations of animal behavior alone cannot fully answer the question of whether or not animals sleep. The answers come from doing experiments in sleep laboratories, using a machine called the electroencephalograph (EEC). The machi

6、ne is connected to animals and measures their brain signals, breathing, heartbeat, and muscle activity. The measurements are different when the animals appear to be sleeping than when they appear to be awake. Using the EEC, scientists have confirmed that all birds and mammals studied in laboratories

7、 do sleep. There is some evidence that reptiles, such as snakes and turtles, do not truly sleep, although they do have periods of rest each day, in which they are quiet and unmoving. They also have discovered that some animals, like chimpanzees, cats, and moles (who live underground), are good sleep

8、ers while others, like sheep, goats, and donkeys, are poor sleepers. Interestingly, the good sleepers are nearly all hunters with resting places that are safe from their enemies. Nearly all the poor sleepers are animals hunted by other animals: they must always be watching for enemies, even when the

9、y are resting.（分数：5.00）(1).According to the author, all animals（分数：1.00）A.spend some time restingB.close their eyes when sleepingC.are good sleepersD.are poor sleepers(2).The statement “Horses and cows, for example, rarely close their eyes“ aims to show that _.（分数：1.00）A.these animals rarely need an

10、y restB.they almost always keep alert to dangerC.they often stay awakeD.their eyes are rarely closed even when they are asleep(3).How can researchers in “sleep laboratories“ tell that the animals they are observing are asleep or not?（分数：1.00）A.They see if the animals respond to light and sound.B.The

11、y do this by observing changes in the animals brain signals, breathing, heartbeat, and muscle activity.C.They see if the animals eyes are closed.D.They can tell this by seeing if the animals lie down or not.(4).According to the research findings mentioned in the passage, reptiles _.（分数：1.00）A.such a

12、s turtles and snakes cannot close their eyesB.cannot be studied with an EECC.do not sleep in the true sense of wordD.do not need to rest(5).Animals that are good sleepers _.（分数：1.00）A.need to have a good sleep after they have exhausted themselves by getting rid of hunting animalsB.need to have a goo

13、d sleep after they get tired from hunting other animalsC.are all mammalsD.almost always have a safe resting place三、Passage 2(总题数：1，分数：5.00)Analysts have had their go at humor, and I have read sortie of this interpretative literature, but without being greatly instructed. Humor can be dissected, as a

14、 frog can, but the thing dies in the process and the innards (内在部分) are discouraging to any but the pure scientific mind.In a newsreel theatre the other day I saw a picture of a man who had developed the soap bubble to a higher point than it had ever before reached. He had become the ace soap bubble

15、 blower of America, had perfected the business of blowing bubbles, refined it, doubled it, squared it, and had even worked himself up into a convenient lather. The effect was not pretty. Some of the bubbles were too big to be beautiful, and the blower was always jumping into them or out of them, or

16、playing some sort of unattractive trick with them. It was, if anything, a rather repulsive sight. Humor is a little like that: it wont stand much blowing up, and it wont stand much poking. It has a certain fragility, an evasiveness, which one had best respect. Essentially, it is a complete mystery.

17、A human frame convulsed with laughter, and the laughter becoming mysterious and uncontrollable, is as far out of balance as one shaken with the hiccoughs or in the throes of a sneezing fit.One of the things commonly said about humorists is that they are really very sad peopleclowns with a breaking h

18、eart. There is some truth in it, but it is badly stated. It would be more accurate, I think, to say that there is a deep vein of melancholy running through everyones life and that the humorist, perhaps more sensible of it than some others, compensates for it actively and positively. Humorists fatten

19、 on trouble. They have always made trouble pay. They struggle along with a good will and endure pain cheerfully, knowing how well it will serve them in the sweet by and by. You find them wrestling with foreign languages, fighting folding ironing boards and swollen drainpipes, suffering the terrible

20、discomfort of tight boot (or as Josh Billings wittily called them, “tire boots“). They pour out their sorrows profitably, in a form that is not quite a fiction not quite a fact either. Beneath the sparking surface of these dilemmas flows the strong tide of human woe.Practically everyone is a manic d

21、epressive of sorts, with his up moments and his down moments, and you certainly dont have to be a humorist to taste the sadness of situation and mood. But there is often a rather fine line between laughing and crying, and if a humorous piece of writing brings a person to the point where his emotiona

22、l responses are untrustworthy and seem likely to break over into the opposite realm, it is because humor, like poetry, has an extra content. It plays close to the big hot fire, which is Truth, and sometimes the reader feels the heat.（分数：5.00）(1).In the first paragraph the author wants to say that _.

23、（分数：1.00）A.just as scientists can dissect a frog, so analysts can dissect humorB.detailed, scientific analysis is not appropriate for humor, for it may make humor lose its aesthetic valueC.some peoples analysis of humor are too scientificD.analysts attempts at humor are not instructive enough to int

24、erest the author(2).The author uses the example of the soap bubble blower to show that _.（分数：1.00）A.skill is required to produce humorB.neither too much exaggeration nor absolute explicitness is fit for humorC.people should perfect the art of humor just as the bubble blower does to the bubblesD.humo

25、r should make people frantic for a while(3).According to the author, humorists differ from ordinary people in the sense that _.（分数：1.00）A.they give vent to their sorrows in a laughable wayB.they have much trouble in their life and they are melancholyC.they are more sensible of the sadness of life an

26、d they endure and express the pain cheerfullyD.they are mostly downs with a breaking heart(4).A humorous piece of writing can make the readers emotional responses untrustworthy because _.（分数：1.00）A.it expresses the truth of the sadness of human life with a sparkling surfaceB.everyone has his happy m

27、oments and unhappy momentsC.there is an obvious line between laughing and cryingD.it is like poetry, very rhythmic(5).The passages success lies in its extensive use of _.（分数：1.00）A.parallelismB.metaphorsC.metonymyD.similes四、Passage 3(总题数：1，分数：5.00)The word science is heard so often in modern times t

28、hat almost everybody has some notion of its meaning. On the other hand, its definition is difficult for many people. The meaning of the term is confused, but everyone should understand its meaning and objectives. Just to make the explanation as simple as possible, suppose science is defined as class

29、ified knowledge (facts).Even in the true sciences distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example

30、, hypotheses and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion.The objectives of science are primarily t

31、he discovery and the subsequent understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature or that questions are unanswerable; he must solve them. Toward that end specialists in the field of biology and related fields of interest are directing much of their t

32、ime and energy.Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. The other is aimed at using knowledge for specific purposesfor instance, improving health, raising standards of living, or creating new consumer

33、 products. In this case knowledge is put to economic use. Such an approach is referred to as applied science.Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. Chemists responsible for many of the discoveries could har

34、dly have anticipated that their findings would one day result in application of such a practical nature as those directly related to life and death. The discoveries of one hit of information opens the door to the discovery of another. Some discoveries seem so simple that one is amazed they were not

35、made years agog however, one should remember that the construction of the microscope had to precede the discovery of the cell. The host of scientists dedicating their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most

36、knowledge is eventually applied.（分数：5.00）(1).To define science we may simply call it _.（分数：1.00）A.the study of unrelated subjectsB.an attempt to explain natural phenomenaC.the study of unrelated fieldsD.classified knowledge(2).Pure science, leading to the construction of a microscope, _.（分数：1.00）A.m

37、ay lead to antiscientific, “impure“ resultsB.necessarily precedes applied science, leading to the discovery of a cellC.is not always as pure as we supposeD.necessarily results from applied science and the discovery of a cell(3).A scientist interested in adding to our general knowledge about oxygen w

38、ould probably call his approach _.（分数：1.00）A.applied scienceB.agriculture scienceC.pure scienceD.environmental science(4).Which of the following statements does the author imply?（分数：1.00）A.Scientists engaged in theoretical research should not be blamed for ignoring the practical side of their discov

39、eries.B.Today few people have any notions of the meaning of science.C.In science, it is not difficult to distinguish fact from fiction.D.Practical-minded people can understand the meaning and objectives of pure scienc(5).The best title for the passage is _.（分数：1.00）A.The Nature of Science and Scient

40、istsB.Biology and the Scientific AgeC.Hypotheses and TheoriesD.On Distinguishing Fact from Fiction五、Passage 4(总题数：1，分数：5.00)In most American cities, the rent for a one-bedroom apartment was $250 or more per month in recent years. In some smaller cities such as Louisville, Kentucky or Jacksonville, F

41、lorida the rent was less, but in larger cities it was more. For example, if you lived in Los Angeles, you had to pay $400 or more to rent a one-bedroom apartment, and the same apartment rented for $625 and up in Chicago. The most expensive rents in the U. S. were in New York City, where you had to p

42、ay at least $700 a month to rent a one-bedroom apartment in most parts of the city.Renters and city planners are worried about the high cost of renting apartments. Many cities now have rent control laws to keep the cost of renting low. These laws help low-income families who cannot pay high rents.Re

43、nt controls in the United States began in 1943 when the government imposed rent controls on all American cities to help workers and the families of soldiers during World War . After the war, only one cityNew Yorkcontinued these World War controls. Recently, more and more cities have returned to rent

44、 controls. At the beginning of the 1980s, nearly one fifth of the people in the United States lived in cities with rent-control laws.Many cities have rent-control laws, but why are rents so high? Builders and landlords blame rent controls for the high rents. Rents are high because there are not enou

45、gh apartments to rent, and they blame rent controls for the shortage of apartments. Builders want more money to build more apartment buildings, and landlords want more money to repair their old apartment buildings. But they cannot increase rents to get this money because of the rent-control laws. As

46、 a result, landlords are not repairing their old apartments, and builders are not building new apartment buildings to replace the old apartment buildings. Builders are building apartments for high-income families, not low income families, so low-income families must live in old apartments that are i

47、n disrepair. Builders and landlords claim that rent-control laws really hurt low income families.Many renters disagree with them. They say that rent control is not the problem. Even without rent controls, builders and landlords will continue to ignore low-income housing because they can make more mo

48、ney from high-income housing. The only answer, they claim, is more rent controls and government help for low-income housing.（分数：5.00）(1).Which of the following would be the best title for the passage?（分数：1.00）A.The Highest Rent.B.Rent Controls.C.Building Apartments for Low-Income Families.D.Rent-Con

49、trol Laws.(2).The aim of the U. S. government in imposing rent controls on American cities in 1943 was to help _.（分数：1.00）A.workers and the families of soldiersB.low income familiesC.up-middle-income familiesD.high-income families(3).This passage implies that the high cost of renting apartments is worried by _.（分数：1.00）A.some city governmentsB.low-income familiesC.renters and city plannersD.all of the above(4).It can be inferred from the passage that rent controls _.（分数：1.00）A.seem unable to contr
