Choose the best word(s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1 (10 points)The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, _1_ this is la

2、rgely because, _2_ animals, we stand upright. This means that our noses are _3_ to perceiving those smells which float through the air, _4_ the majority of smells which stick to surfaces. In fact, _5_, we are extremely sensitive to smells, _6_ we do not generally realize it. Our noses are capable of

3、 _7_ human smells even when these are _8_ to far below one part in one million.Strangely, some people find that they can smell one type of flower but not another, _9_ others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate _10_

4、smell receptors in the nose. These receptors are the cells which sense smells and send _11_ to the brain. However, it has been found that even people insensitive to a certain smell _12_ can suddenly become sensitive to it when _13_ to it often enough.The explanation for insensitivity to smell seems

5、to be that the brain finds it _14_ to keep all smell receptors working all the time but can _15_ new receptors if necessary. This may _16_ explain why we are not usually sensitive to our own smellswe simply do not need to be. We are not _17_ of the usual smell of our own house, but we _18_ new smell

Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1 (40 points

10、)Text 1Everybody loves a fat pay rise. Yet pleasure at your own can vanish if you learn that a colleague has been given a bigger one. Indeed, if he has a reputation for slacking, you might even be outraged. Such behaviour is regarded as “all too human,” with the underlying assumption that other anim

11、als would not be capable of this finely developed sense of grievance. But a study by Sarah Brosnan and Frans de Waal of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that it is all too monkey, as well.The researchers studied the behaviour of female brown cap

12、uchin monkeys. They look cute. They are good-natured, co-operative creatures, and they share their food readily. Above all, like their female human counterparts, they tend to pay much closer attention to the value of “goods and services” than males.Such characteristics make them perfect candidates f

13、or Dr. Brosnans and Dr. de Waals study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to exchange pieces of rock for slices of cucumber. However, when two monkeys were placed in separate but adjoining chambers, so that eac

14、h could observe what the other was getting in return for its rock, their behaviour became markedly different.In the world of capuchins, grapes are luxury goods (and much preferable to cucumbers). So when one monkey was handed a grape in exchange for her token, the second was reluctant to hand hers o

15、ver for a mere piece of cucumber. And if one received a grape without having to provide her token in exchange at all, the other either tossed her own token at the researcher or out of the chamber, or refused to accept the slice of cucumber. Indeed, the mere presence of a grape in the other chamber (

16、without an actual monkey to eat it) was enough to induce resentment in a female capuchin.The researchers suggest that capuchin monkeys, like humans, are guided by social emotions. In the wild, they are a co-operative, group-living species. Such co-operation is likely to be stable only when each anim

17、al feels it is not being cheated. Feelings of righteous indignation, it seems, are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However, whether such a sense of fairness evolved independ ently in capuchins

18、and humans, or whether it stems from the common ancestor that the species had 35 million years ago, is, as yet, an unanswered question.21. In the opening paragraph, the author introduces his topic by _.A posing a contrastB justifying an assumptionC making a comparisonD explaining a phenomenon22. The

19、 statement “it is all too monkey” (Last line, Paragraph l) implies that _.A monkeys are also outraged by slack rivalsB resenting unfairness is also monkeys natureC monkeys, like humans, tend to be jealous of each otherD no animals other than monkeys can develop such emotions23. Female capuchin monke

20、ys were chosen for the research most probably because they are _.A more inclined to weigh what they getB attentive to researchers instructionsC nice in both appearance and temperamentD more generous than their male companions24. Dr. Brosnan and Dr. de Waal have eventually found in their study that t

21、he monkeys _.A prefer grapes to cucumbersB can be taught to exchange thingsC will not be co-operative if feeling cheatedD are unhappy when separated from others25. What can we infer from the last paragraph?A Monkeys can be trained to develop social emotions.B Human indignation evolved from an uncert

22、ain source.C Animals usually show their feelings openly as humans do.D Cooperation among monkeys remains stable only in the wild.Text 2Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didnt know for sure? That the evidence was inconc

23、lusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.There are upsetting parallels today, as scientists

24、in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earths atmosphere is definitely warming and that the problem is largely man-made. The clear message is th

25、at we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panels report: “Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our natio

26、n and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions.”Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that its OK to keep pouring fumes into t

27、he air until we know for sure. This is a dangerous game: by the time 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now.Fortunately, the White House is starting to pay attention. But its obvious that a ma

28、jority of the presidents advisers still dont take global warming seriously. Instead of a plan of action, they continue to press for more research - a classic case of “paralysis by analysis.”To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic resear

29、ch. But research alone is inadequate. If the Administration wont take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising sta

30、rt. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.26. An argument made by supporters of smoking was that _.A there was no scientific e

31、vidence of the correlation between smoking and deathB the number of early deaths of smokers in the past decades was insignificantC people had the freedom to choose their own way of lifeD antismoking people were usually talking nonsense27. According to Bruce Alberts, science can serve as _.A a protec

32、torB a judgeC a criticD a guide28. What does the author mean by “paralysis by analysis” (Last line, Paragraph 4)?A Endless studies kill action.B Careful investigation reveals truth.C Prudent planning hinders progress.D Extensive research helps decision-making.29. According to the author, what should

33、 the Administration do about global warming?A Offer aid to build cleaner power plants.B Raise public awareness of conservation.C Press for further scientific research.D Take some legislative measures.30. The author associates the issue of global warming with that of smoking because _.A they both suf

34、fered from the governments negligenceB a lesson from the latter is applicable to the formerC the outcome of the latter aggravates the formerD both of them have turned from bad to worseText 3Of all the components of a good nights sleep, dreams seem to be least within our control. In dreams, a window

35、opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just “mental noise” - the rand

36、om byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the minds emotional thermostat, regulating moods while the brain is “off-line.” And one leading authority says that these intensely powerful mental events can be not only harnessed but

37、actually brought under conscious control, to help us sleep and feel better, “Its your dream,” says Rosalind Cartwright, chair of psychology at Chicagos Medical Center. “If you dont like it, change it.”Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye moveme

38、nt) sleep - when most vivid dreams occur - as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and

39、 reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day.” says Stanford sleep researcher Dr. William Dement.The link between dreams and emotions shows up among the patients in Cartwrights clinic. Most people seem to have more bad dream

40、s early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we dont always think about the emotional significance of the days events - until, it app

41、ears, we begin to dream.And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs,

42、try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.At the end of the day, theres probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “we wake up in a panic,” Cartwright says. Terroris

43、m, economic uncertainties and general feelings of insecurity have increased peoples anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep - or rather dream - on it and youll feel better

44、 in the morning.31. Researchers have come to believe that dreams _.A can be modified in their coursesB are susceptible to emotional changesC reflect our innermost desires and fearsD are a random outcome of neural repairs32. By referring to the limbic system, the author intends to show _.A its functi

45、on in our dreamsB the mechanism of REM sleepC the relation of dreams to emotionsD its difference from the prefrontal cortex33. The negative feelings generated during the day tend to _.A aggravate in our unconscious mindB develop into happy dreamsC persist till the time we fall asleepD show up in dreams early at night34. Cartwright seems to suggest that _.A waking up in time is essential to the ridding of bad dre
