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, 1this is largely because, 2animals, we stand upright. This means that our noses are 3to 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, 6we do not generally realize it. Our noses are capable of 7human smells even when these are 8to 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 10smell receptors in the nose. These receptors are the cells which sense smells and send 11to the brain. However, it has been found that even people insensitive to a certain smell 12can suddenly become sensitive to it when 13to it often enough.The explanation for insensitivity to smell seems to be that the brain finds it 14to keep all smell receptors working all the time but can 15new receptors if necessary. This may 16explain why we are not usually sensitive to our own smells—we simply do not need to be. We are not 17of the usual smell of our own house, but we 18new smells when we visit someone else’s. The brain finds it be st to keep smell receptors 19for unfamiliar and emergency signals 20the smell of smoke, which might indicate the danger of fire.1. [A] although [B] as [C] but [D] while2.

Answer the questions below each text by choosing [A], [B], [C] or D. Mark your answers on ANSWER SHEET 1 (40 points)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 animals 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 capuchin 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 attent ion to the value of “goods and services” than males.Such characteristics make them perfect candidates for Dr. Brosnan’s and Dr. de W aal’s 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 each 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 over 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 (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 animal 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 independently in capuchins 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 contrast[B] justifying an assumption[C] making a comparison[D] explaining a phenomenon22. The statement “it is all too monkey” (Last line, Paragraph l) implies that ________.[A] monkeys are also outraged by slack rivals[B] resenting unfairness is also monkeys’ nature[C] monkeys, like humans, tend to be jealous of each other[D] no animals other than monkeys can develop such emotions23. Female capuchin monkeys were chosen for the research most probably because they are________.[A] more inclined to weigh what they get[B] attentive to researchers’ instructions[C] nice in both appearance and temperament[D] more generous than their male companions24. Dr. Brosnan and Dr. de Waal have eventually found in their study that the monkeys ________.[A] prefer grapes to cucumbers[B] can be taught to exchange things[C] will not be co-operative if feeling cheated[D] 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 uncertain 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 didn’t know for sure? That the evidence was inconclusive, 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 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 Earth’s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel’s 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 nation 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 globalwarming is incomplete, that it’s OK to keep pouring fumes into the 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 it’s obvious that a majority of the president’s advisers still don’t 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 research. But research alone is inadequate. If the Administration won’t 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 start. 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 evidence of the correlation between smoking and death[B] the number of early deaths of smokers in the past decades was insignificant[C] people had the freedom to choose their own way of life[D] antismoking people were usually talking nonsense27. According to Bruce Alberts, science can serve as ________.[A] a protector[B] a judge[C] a critic[D] 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 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 suffered from the government’s negligence[B] a lesson from the latter is applicable to the former[C] the outcome of the latter aggravates the former[D] both of them have turned from bad to worseText 3Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window 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 random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermost at, 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 actually brought under conscious control, to help us sleep and feel better, “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) 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 reas oning) is relatively quiet. “We wake up from dreams happy o r 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 Cartwright’s clinic. Most people seem to have more bad dreams 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 don’t always think about the emotional significance of the day’s events -- until, it appears, 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, 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, there’s 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. Terrorism, economic uncertainties and general feelings of insecurity have increased p eople’s 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 you’ll feel better in the morning.31. Researchers have come to believe that dreams ________.[A] can be modified in their courses[B] are susceptible to emotional changes[C] reflect our innermost desires and fears[D] are a random outcome of neural repairs32. By referring to the limbic system, the author intends to show ________.[A] its function in our dreams[B] the mechanism of REM sleep[C] the relation of dreams to emotions[D] its difference from the prefrontal cortex33. The negative feelings generated during the day tend to ________.[A] aggravate in our unconscious mind[B] develop into happy dreams[C] persist till the time we fall asleep[D] show up in dreams early at night34. Cartwright seems to suggest that ________.[A] waking up in time is essential to the ridding of bad dreams[B] visualizing bad dreams helps bring them under control[C] dreams should be left to their natural progression[D] dreaming may not entirely belong to the unconscious35. What advice might Cartwright give to those who sometimes have bad dreams?[A] Lead your life as usual.[B] Seek professional help.[C] Exercise conscious control.[D] Avoid anxiety in the daytime.Text 4Americans no longer expect public figures, whether in speech or in writing, to command the English language with skill and gift. Nor do they aspire to such command themselves. In his latest book, Doing Our Own Thing: The Degradation of Language and Music and Why We Should, Like, Care, John McWhorter, a linguist and controversialist of mixed liberal and conservative views, sees the triumph of 1960s counter-culture as responsible for the decline of formal English.Blaming the permissive 1960s is nothing new, but this is not yet another criticism against the decline in education. Mr. McWhorter’s academic speciality is language history and change, and he sees the gradual disappearance of “whom,” for example, to be natural and no more regrettable than the loss of the case-endings of Old English.But the cult of the authentic and the personal, “doing our own thing,” has spelt the death of formal speech, writing, poetry and music. While even the modestly educated sought an elevated tonewhen they put pen to paper before the 1960s, even the most well regarded writing since then has sought to capture spoken English on the page. Equally, in poetry, the highly personal, performative genre is the only form that could claim real liveliness. In both oral and written English, talking is triumphing over speaking, spontaneity over craft.Illustrated with an entertaining array of examples from both high and low culture, the trend that Mr. McWhorter documents is unmistakable. But it is less clear, to take the question of his subtitle, why we should, like, care. As a linguist, he acknowledges that all varieties of human language, including non-standard ones like Black English, can be powerfully expressive -- there exists no language or dialect in the world that cannot convey complex ideas. He is not arguing, as many do, that we can no longer think straight because we do not talk proper.Russians have a deep love for their own language and carry large chunks of memorized poetry in their heads, while Italian politicians tend to elaborate speech that would seem old-fashioned to most English-speakers. Mr. McWhorter acknowledges that formal language is not strictly necessary, and proposes no radical education reforms -- he is really grieving over the loss of something beautiful more than useful. We now take our English “on paper plates instead of china.” A shame, perhaps, but probably an inevitable one.36. According to McWhorter, the decline of formal English ________.[A] is inevitable in radical education reforms[B] is but all too natural in language development[C] has caused the controversy over the counter-culture[D] brought about changes in public attitudes in the 1960s37. The word “talking” (Line 6, Paragraph 3) denotes ________.[A] modesty[B] personality[C] liveliness[D] informality38. To which of the following statements would McWhorter most likely agree?[A] Logical thinking is not necessarily related to the way we talk.[B] Black English can be more expressive than standard English.[C] Non-standard varieties of human language are just as entertaining.[D] Of all the varieties, standard English can best convey complex ideas.39. The description of Russians’ love of memorizing poetry shows the author’s ________.[A] interest in their language[B] appreciation of their efforts[C] admiration for their memory[D] contempt for their old-fashionedness40. According to the last paragraph, “paper plates” is to “china” as ________.[A] “temporary” is to “permanent”[B] “radical” is to “conservative”[C] “functional” is to “artistic”[D] “humble” is to “noble”Part BDirections:In the following text, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the gaps. Mark your answers on ANSWER SHEET 1. (10 points) Canada’s premiers (the leaders of provincial governments), if they have any breath left after complaining about Ottawa at their late July annual meeting, might spare a moment to do something, together, to reduce health-care costs.They’re all groaning about soaring health budgets, the fastest-growing component of which are pharmaceutical costs.41. ________What to do? Both the Romanow commission and the Kirby committee on health care -- to say nothing of reports from other experts -- recommended the creation of a national drug agency. Instead of each province having its own list of approved drugs, bureaucracy, procedures and limited bargaining power, all would pool resources, work with Ottawa, and create a national institution.42. ________But “national”doesn’t have to mean that. “National”could mean interprovincial -- provinces combining efforts to create one body.Either way, one benefit of a “national”organization would be to negotiate better prices, if possible, with drug manufacturers. Instead of having one province -- or a series of hospitals within a province -- negotiate a price for a given drug on the provincial list, the national agency would negotiate on behalf of all provinces.Rather than, say, Quebec, negotiating on behalf of seven million people, the national agency would negotiate on behalf of 31 million people. Basic economics suggests the greater the potential consumers, the higher the likelihood of a better price.43. ________A small step has been taken in the direction of a national agency with the creation of the Canadian Co-ordinating Office for Health Technology Assessment, funded by Ottawa and the provinces. Under it, a Common Drug Review recommends to provincial lists which new drugs should be included. Predictably, and regrettably, Quebec refused to join.A few premiers are suspicious of any federal-provincial deal-making. They (particularly Quebecand Alberta) just want Ottawa to fork over additional billions with few, if any, strings attached. That’s one reason why the idea of a national list hasn’t gone anywhere, while drug costs keep rising fast.44. ________Premiers love to quote Mr. Romanow’s report selectively, especially the parts about more federal money. Perhaps they should read what he had to say about drugs: “A national drug agency would provide governments more influence on pharmaceutical companies in order to constrain the ever-increasing cost of drugs.”45. ________So when the premiers gather in Niagara Falls to assemble their usual complaint list, they should also get cracking about something in their jurisdiction that would help their budgets and patients.[A] Quebec’s resistance to a national agency is provincialist ideology. One of the first advocatesfor a national list was a researcher at Laval University. Quebec’s Drug Insurance Fund has seen its costs skyrocket with annual increases from 14.3 per cent to 26.8 per cent![B] Or they could read Mr. Kirby’s report: “the substantial buying power of such an agencywould strengthen the public prescription-drug insurance plans to negotiate the lowest possible purchase prices from drug companies.”[C] What does “national”mean? Roy Romanow and Senator Michael Kirby recommended afederal-provincial body much like the recently created National Health Council.[D] The problem is simple and stark: health-care costs have been, are, and will continue toincrease faster than government revenues.[E] According to the Canadian Institute for Health Information, prescription drug costs haverisen since 1997 at twice the rate of overall health-care spending. Part of the increase comes from drugs being used to replace other kinds of treatments. Part of it arises from new drugs costing more than older kinds. Part of it is higher prices.[F] So, if the provinces want to run the health-care show, they should prove they can run it,starting with an interprovincial health list that would end duplication, save administrative costs, prevent one province from being played off against another, and bargain for better drug prices.[G] Of course, the pharmaceutical companies will scream. They like divided buyers; they canlobby better that way. They can use the threat of removing jobs from one province to another. They can hope that, if one province includes a drug on its list, the pressure will cause others to include it on theirs. They wouldn’t like a national agency, but self-interest would lead them to deal with it.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2. (10 points)It is not easy to talk about the role of the mass media in this overwhelmingly significant phasein European history. History and news become confused, and one’s impressions tend to be a mixture of skepticism and optimism. 46) Television is one of the means by which these feelings are created and conveyed -- and perhaps never before has it served so much to connect different peoples and nations as in the recent events in Europe. The Europe that is now forming cannot be anything other than its peoples, their cultures and national identities. With this in mind we can begin to analyze the European television scene. 47) In Europe, as elsewhere, multi-media groups have been increasingly successful: groups which bring together television, radio, newspapers, magazines and publishing houses that work in relation to one another. One Italian example would be the Berlusconi group, while abroad Maxwell and Murdoch come to mind.Clearly, only the biggest and most flexible television companies are going to be able to compete in such a rich and hotly-contested market. 48) This alone demonstrates that the television business is not an easy world to survive in, a fact underlined by statistics that show that out of eighty European television networks, no less than 50% took a loss in 1989.Moreover, the integration of the European community will oblige television companies to cooperate more closely in terms of both production and distribution.49) Creating a “European identity” that respects the different cultures and traditions which go to make up the connecting fabric of the Old Continent is no easy task and demands a strategic choice -- that of producing programs in Europe for Europe. This entails reducing our dependence on the North American market, whose programs relate to experiences and cultural traditions which are different from our own.In order to achieve these objectives, we must concentrate more on co-productions, the exchange of news, documentary services and training. This also involves the agreements between European countries for the creation of a European bank for Television Production which, on the model of the European Investments Bank, will handle the finances necessary for production costs. 50) In dealing with a challenge on such a scale, it is no exaggeration to say “Unit ed we stand, divided we fall” -- and if I had to choose a slogan it would be “Unity in our diversity.” A unity of objectives that nonetheless respect the varied peculiarities of each country.Section III WritingPart A51.

While here’s on question that continuous stress is harmful, several studies suggest that challenging situations in which you’re able to rise to the occasion can be good for you..In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they stress that you can manage also boost immune(免疫的) function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects through a gory(血淋淋的) video on surgical procedures. Those who did well on the memory test had an increase in levels of immunoglobulin A, an antibody that’s the body’sfirst line of defense against germs. The video-watchers experienced a downturn in the antibody.Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. “They can help nerve cells handle information and put it into sto rage,” says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain.“Sustained stress is not good for you,” says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity ,”It’s the occasional burst of stress or brief exposure to stress that could be protective.”21. The passage is mainly about______A)how to avoid stressfulB)how to cope with stress effectivelyC)the benefits of manageable tressD)the effect of stress harmonies on memory22. The word “shun”(Line 1,Para.1) most probably means________.A)cut down onB)stay away fromD)run out ofC)put up with23.We can conclude from the study of the 158 nurses in 2001 that_______A)people who can’t get their job done experience more stressB)doing challenging work may be good for one’s healthC)stress will weaken the body’s defense against germsD)people under stress tend to have a poor memory24.In the experiment described in Paragraph 3,the video-watchers experienced a downturn in the antibody because______.A) the outcome was beyond their controlB)they knew little about surgical proceduresC)they felt no pressure while watching the videoD) the video was not enjoyable at all25.Dr. Bruce McEwen of Rockefeller University believes that______.A)a person’s memory is determined by the level of hormones in his bodyB)a person’s memory improves with continued experience of stress.C)stress hormones have lasting positive effects on the brainD)short bursts of stress hormones enhance memory functionPassage TwoQuestions 26 to 30 are based on the following passage.Just five one-hundredths of an inch thick, light golden in color and with a perfect “saddle curl,” the Lay’s potato chip seems an unlikelyweapon for global domination. But its maker. Frito-Lay. Thinks otherwise.” Potato chips are a snack food for the world,” said Salman Amin, the company’s head of global marketing. Amin believes there is no corner of the world that can resist the charms of a Frito-Lay potato chip.Frito-Lay is the biggest snack maker in America. owned by PepsiCo. And accounts for over half of the parent company’s $3 billion annual profits. But the U.S. snack food market is largely saturated, and to grow. the company has to look overseas.Its strategy rests on two beliefs: first a global product offers economies of scale with which local brands cannot compete. And second, consumers in the 21st century are drawn to “global” as a concept. ”Global” does not mean products that are consciously identified as American, but ones than consumes-especially young people-see as part of a modem, innovative(创新的)world in which people are linked across cultures by shared beliefs and tastes. Potato chips are an American invention, but most Chinese, for instance, do not know than Frito-Lay is an American company. Instead, Riskey, the company’s research and development head, would hope they associate the brand with the new world of global communications and business.With brand perception a crucial factor, Riskey ordered a redesign of the Frito-Lay logo(标识).The logo, along with the company’s long-heldmarketing image of the “irresistibility” of its chips. would help facilitate the company’s global expansion.The executives acknowledge that they try to swing national eating habits to a food created in America, but they deny that amounts to economic imperialism. Rater, they see Frito-Lay as spreading the benefits of free enterprise across the world. “We’re making products in those countries, we’re adapting them to the tastes of those countries, building businesses and employing people and changing lives,” said Steve Reinemund, PepsiCo’s chief executive.26.It is the belief of Frito-Lay’s head of global marking that_____.A) People the world over enjoy eating their company’s potato chipsB) The light golden color enhances the charm of their company’s potato chipsC) Their company must find new ways to promote domestic sales.D) Potato chips can hardly be used as a weapon to dominate the world market27.What do we learn about Frito-Lay from Paragraph 2?A) It gives half of its annual profits to its parent company.B) It needs to turn to the word market for development.C) Its products use to be popular among overseas consumers.D) Its expansion has caused fierce competition in the snack marker.28.One of the assumptions on which Frito-Lay bases its developmentstrategy is that_____.A)products identified as American will have promising market valueB)products suiting Chinese consumers’needs bring more profitsC)local brands cannot compete successfully with American brandsD)consumers worldwide today are attracted by global brands29.Why did Riskey have the Frito-Lay logo redesigned?A)To suit changing tastes of young consumers.B)To compete with other American chip producers.C)To change the company’s long-held marketing image.D)To promote the company’s strategy of globalization.30.Frito-Lay’s executives claim that the promoting of American food in the international market_____.A)will be in the interest of the local peopleB)will lead to economic imperialismC)won’t spoil the taste of their chipsD)won’t affect the eating habits of the local peoplePassage ThreeQuestions 31 to 35 are based on the following passage.If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.If you say to your children “I’m sorry I got angry with you, but …” what follows that “but” can render the apology ineffective: ” I had a bad day” or “your noise was giving me a headache ” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.Another method by which people appear to apologize without actually doing so is to say “I’m sorry you’re upset” ; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.Then there is the general, all covering apology, which avoids the necessity of identifying a specific act that was particularly hurtful or insulting, and which the person who is apologizing should promise never to do again. Saying “I’m useless as a parent” does not commit a person to any specific improvement.These pseudo-apologies are used by people who believe saying sorry shows weakness, Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not resort to these pseudo-apologies.But even when presented with examples of genuine contrition, children still need help to become a ware of the complexities of saying sorry. A three-year-old might need help in understanding that other children feel pain just as he does, and that hitting a playmate over thehead with a heavy toy requires an apology. A six-year-old might need reminding that spoiling other children’s expectations can require an apology. A 12-year-old might need to be shown that raiding the biscuit tin without asking permission is acceptable, but that borrowing a parent’s clothes without permission is not.31.If a mother adds ”but” to an apology,________.A) the child may find the apology easier to acceptB) the child may feel that he owes her an apologyC) she does not realize that the child has been hurtD) she doesn’t feel that she should have apologized32.According to the author, saying “I’m sorry you’re upset” most probably means”_______”A)You have good reason to get upsetB)I apologize for hurting your feelingsC)I’m at fault for making you upsetD)I’m aware you’re upset ,but I’m not to blame33.It is not advisable to use the general, all-covering apology because______.A)it is hurtful and insultingB)it is vague and ineffectiveC)it may make the other person feel guiltyD)it gets one into the habit of making empty promises34.We learn from the last paragraph that in teaching children to say sorry______.A)their ages should be taken into accountB)parents should be patient and tolerantC)parents need to set them a good exampleD)the complexities involved should be ignored35.It can be inferred from the passage that apologizing properly is _________.A)not necessary among family membersB)a sign of social progressC) not as simple as it seemsD)a social issue calling for immediate attentionPassage FourQuestion 36 to 40 are based on the following passage.In communities north of Denver, residents are pitching in to help teachers and administrators as the Vrain school District tries to solve a $13.8 million budget shortage blamed on mismanagement. ”We’re worried about our teachers and principals, and we really don’t want to lose them because of this,” one parent sail. “If we can help ease their financial burden, we will. ”Teachers are grateful, but know it may be years before the district is solvent(有综合能力的). They feel really good about the parent support,but they realize it’s impossible for then to solve this problem.The 22,000-student district discovered the shortage last month. “It’s extraordinary. Nobody would have imagined something happening like this at this level,” said State Treasurer Mi ke Coffman.Coffman and district officials last week agreed on a state emergency plan freeing yp a $9.8 million loan that enabled the payroll(工资单) to be met for 2,700 teachers and staff in time for the holidays.District officials also took $1.7 million from student-activity accounts its 38schools.At Coffman’s request, the District Attorney has begun investigating the district’s finances. Coffman says he wants to know whether district officials hid the budget shortage until after the November election., when voters approved a $212 million bond issue for schools.In Frederick, students’parents are buying classroom supplies and offering to pay for groceries and utilities to keep first-year teachers and principals in their jobs.Some $36,000 has been raised in donations from Safeway. A Chevrolet dealership donated $10,000 and forgave the district’s $10,750 bill for renting the driver educating cars. IBM contributed 4,500 packs of paper.“We employ thousands of people in this community,” said Mitch Carson, a hospital chief executive, who helped raise funds. “We havechildren in the school, and we see how they could be affected.”At Creek High School, three students started a website that displays newspaper articles, district information and an email forum(论坛)。

Then mark the corresponding letter on the Answer Sheet with a single line through the centre.Passage OneThe majority of astronauts from America have been men. At the start of the space programme there was strong resistance from some people against having women in space. However, some women were very keen to become astronauts and in the end they were successful. In 1978, NASA began the first training programme for women astronauts.Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other ways they were very different. Both of them were on Flight STS-51-L. Judy Resnick was born in 1949 and studied engineering at university and went on to obtain a PhD in 1977. She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space. During that flight, she helped to launch three new satellites and she carried out a programme of research. She was, in many ways, a professional astronaut whose whole life was devoted to space travel.Christa McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space and encourage everyone of them to be interested in space travel. Christa was a secondary teacher in history and social studies. She was a gifted teacher and she was selected from over 11,000 applicants to go on flightSTS-51-L. She was also a very good communicator and she immediately established a very good relationship with the news media (radio, television and newspapers). It was partly because of this that there was a great deal of interest and excitement about the flight. Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space. Millions of people were watching her flight with great interest. It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people.Questions 21 to 25 are based on the first passage.21. Why did NASA begin the first training programmefor women in 1978? (A)22. Which of the following is true about Judy? (C)23. When was Christa McAuliffe born? (B)24. Why was Christa McAuliffe chosen for training? (C)25. What would be the best title for the passage?(A)Passage TwoAs more women in the United States move up the professional ladder, more are finding it necessary to make business trips alone. Since this is new for many, some tips are certainly in order. If you are married, it is a good idea to encourage your husband and children to learn to cook a few simple meals while you are away. They will be much happier and probably they will enjoy the experience. If you will be eating alone a good deal, choose good restaurants. In the end, they will be much better for your digestion. You may also find it useful to call the restaurant in advance and state that you will be eating alone. You will probably get better service and almost certainly a better table. Finally, and most importantly, anticipate your travel needs as a businesswoman; this starts with lightweight luggage which you can easily manage even when fully packed. Take a folding case inside your suitcase; it will come in extremely handy for dirty clothes, as well as for business documents and papers you no longer need on the trip. And make sure you have a briefcase so that you can keep currently required papers separate. Obviously, experience helps, but you can make things easier on yourself from the first by careful planning, so that right from the start you really can have a good trip!Questions 26 to 30 are based on the second passage.26. Who is the author's intended audience? (C)27. Which of the following can be inferred from the passage? (A)28. Why is lightweight luggage important for the travelling businesswomen? (B)29. In this passage, what advice does the author have for married women? (B)30. Where would this passage most likely appear? (A)Part II Vocabulary and Structure (5 minutes, 10 points)31. D 32. C 33.

You should decide on the best choice and mark the corresponding letter on the Answer Sheet.Passage 1Each Indian（印第安人）was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates（游戏伙伴）would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a-Horse. So an Indian’s name told his record or described the kind of man he was.A man was given many chances to improve his name, however. If in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelvenames -- all good and each better than the last.An Indian’s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three of four times when this happened. It is the rarest honor for a person -- the honor of assuming his father’s name.21. Names were important to an Indian because .A. they were given by the chief of the tribeB. they described the character of a manC. he got his names from the older generationD. names were earned in battle22. An Indian could be given the second name by .A. his fatherB. the enemyC. the chief of the tribeD. his childhood friends23. The greatest honor an Indian could earn was .A. a victory in his first battle against the enemyB. a name given by the chiefC. a ceremony to get his real nameD. the right to use his father’s name 24. If an Indian had more than ten names, it meant that .A. many people in the tribe liked himB. he was a great fighterC. he had a lot of friendsD. he had fought in fewer than ten battles25. Which of the following statements is not true according to the passage?A. The names given by the playmates of an Indianwere usually not pleasant.B. The life name of an Indian was earned in battle.C. An Indian could throw away his birth namewhere he was old enough to earn one forhimself.D. The Indians themselves were not allowed to give their names away.Passage 2One of the strongest reasons for the raising of the school leaving age (ROSLA) has been that it will bring us nearer to the ideal of “equal opportunity”.Many people like to think of our present system of schooling as providing plenty of steps up the ladder of success for clever children. It would be good to think that no one who is really bright can be missed out when the state system is apparently so thorough. It is obvious, for instance, that many children from less rich homes reach university or do well in other ways.Unfortunately, we now have plenty of evidence that many children of every level of ability do muchless well than they could. For instance, during the years of national military service it was possible to test the intelligence（智力）of all male 18-20 year olds. Half of those soldiers who were placed in the two highest ability groups had left schools at 15.It has also been shown that the percentage of working class children going to university is almost the same now as it was in 1939. One study of 5000 children from birth to 21 years old indicated that up to half the bright pupils from working class homes left school when they reached 16 years old. Moreover, there is no difference in intelligence between the sexes, but far more boys than girls stay in education after 16.It is clear from this and much other evidence that many children are still leaving school too early to benefit from the prizes -- money, social respectability, and interesting jobs, which higher education gives. It is clear too that the reasons why such children leave have much to do with their social circumstances（情形）. Their parents often need the extra money another wage-earner can bring in; they do not value education for itself because their own was probably dull and unhappy. It is not so much that they force their sons and daughters to leave school, rather that they tend to say, “It’s up to you”.26. It is hoped that ROSLA will give all children .A. a more enjoyable time at schoolB. the same chances in societyC. the right to a better schoolD. higher scores in intelligence tests27. People would like to think that.A. equal numbers of poor and rich children reach universityB. those with the least money get the best educationC. intelligent children are always chosen by the systemD. only clever children do well28. Working class children are felt to be at a disadvantage because .A. many of the clever ones leave school earlyB. fewer go to university than ever beforeC. more than half leave school when they are 16D. fewer boys than girls stay at school after 1629. Many children leave school early because .A. their social circumstances make them unhappyB. they have to work to support their family’s incomeC. their school is a dull and unhappy placeD. their parents don’t allow them to make their own decisions30. This article shows that equal opportunity in education .A. is a thing of the pastB. has not yet been achievedC. is there for those who merit itD. has greatlyimproved our societyPassage 3Officials have long been aware of the problems in gathering crime statistics（统计数字）. In some cases, the problems lie in the reporting procedure that is used in making the final crime figure reports. The number of actual crimes reported to police is not always made public.Other problems arise in decidin g which figures accurately reflect crime rates. For example, court statistics do not reflect all the arrests that are made since charges are sometimes dismissed. Arrest statistics are also weak because an arrest is not always made for every crime.Total figures on crimes reported to the police also do not give a full picture. Crimes often are not reported to the police either because the victims are afraid or because they or witnesses feel that nothing will be done to punish the criminal. One study indicated another problem. It found that the police did not respond to a reported crime as often as 20 percent of the time. This situation applied particularly to large cities.Several long-term studies have been undertaken to get a better picture of the full extent of the crime problem. The approach taken in these studies has been to survey a large group of families regularly for a period of several months. The participants in the studies are asked whether or not they have been victims of crimes. In this manner, investigators are better able to win the confidence of the participants. The investigators also believe the crime figures obtained are more accurate. Usually, the findings in such studies reveal much higher crime rates than those officially reported.31. According to the passage, a major improvement inthe gathering of accurate statistics on crime has been the use of .A. court statisticsB. arrest statisticsC. police reportsD. long-range surveys32. All of the following can be con cluded from thepassage EXCEPT that .A. crime figures will vary according to thereporting method usedB. no reporting method is ever 100 percentaccurateC. some reporting procedures are more accuratethan othersD. all crime figures are gathered through thesurvey method33. According to the passage, it can be inferred thatcourt statistics are likely to be most useful in determining .A. the average lengths of jail sentences for certaincrimesB. which areas of a city are most dangerousC. which crimes are committed most oftenD. which crimes go unpunished most often34. As it is used in the fourth paragraph of the passage,the word “participant” means.A. a person who applies, esp. for a job, etc.B. a person or group of people who participate insomethingC. a person being tested in an examinationD. a person who investigates35. According to the content of the passage, the articleis probably selected from the book on .A. statisticsB. mathematicsC. behavioral scienceD. social psychology Passage 4The chief purpose of work is not to produce things but to build the man. It is not so important what shape or form our work may take; what is vitally important is our attitude toward that work.Even if the particular duty is one which doesn’t seem worth doing, if you must do it, it is important to do it right. Even if no one else will ever know whether you did it right or not, you will know. By making a commitment（承诺）to quality work, you make a commitment to yourself to develop your abilities and self-respect, to do the best you can do and be the best you can be. When you do as little as possible or just enough to get by, you are not merely cheating your employer, your customers, your clients, and your co-workers, but most importantly, you cheat yourself. You cheat yourself out of an opportunity to develop pride and self-worth. You cheat yourself out of an opportunity to meet a challenge and develop your own inner powers and abilities. You may be able to get away with cheating others, but you never get away with cheating yourself.Thus, the key is a commitment to yourself to use every possible opportunity for self-development and treat every work assignment, no matter how small or boring, as a challenge that can be used in your development.Work is a projection（投影）of self. Consciousness （感觉，意识）can regard any job as a potential opportunity for self-expression, for play, for creativity, for the furtherance（推动）of social objectives, and it can arrange the factors in the job so that they form a means of self-expression.Most jobs contain at least some limited options for creativity. To the extent that any job can be done in different ways, the job presents you with an opportunity to project your unique abilities and values into that job. Any type of communication, written or spoken, presents a significant opportunity for creative expression. Even if your efforts are reviewed and must be toned down to fit into the mol e（模型）of your organization, there is always a slight opening through which you can project your unique personality. Use these opportunities to express and confirm your existence.36. What can work assignments offer people?A. An opportunity to develop on eselfB. A chance to get away with cheating themselves.C. Few options for creativityD. A way to get rid of your unique personality37. Which of the following statements is not true?A. Sometimes you have to adjust yourself to yourwork.B. There is space for you to show your creativity.C. Work must be done in one way in order to bethe most efficient.D. You may never cheat yourself.38. The most important thing about workis .A. to produce thingsB. the shape one’s wo rktakesC. the amount of money it makesD. one’sattitude towards the workPassage 5Do parents owe their children anything? Yes, they owe them a great deal.One of their chief duties is to give their children a sense of personal worth, for self-esteem（自尊心）is the basis of a good mental health. A youngster who is often made to feel stupid, often compared to brighter brothers, sister, or cousins, will not feel confident and become so afraid of failing, that he (or she) won’t try at all. Of course, they should be corrected when they do wrong; this is the way children learn. But the criticisms should be balanced with praises.Parents owe their children firm guidance and consistent discipline. It is frightening for a youngster to feel that he is i n charge of himself; it’s like being in a car without brakes（刹车）. The parent who says “No” when other parents say “Yes” sends a double message. He is also saying: “I love you, and I am ready to risk your anger, because I don’t want you to get into trouble.”Parents owe their children a comfortable feeling about their body, and enough information about sex to balance the wrong information that they will surely receive from their friends.Parents owe their children privacy（隐私权）and respect for their personal things. This means not borrowing things without being permitted, not reading diaries and mail, not looking through pockets. If a mother feels that she must read her daughter’s diary to know what is going on, the communication between them must be pretty bad.Parents own their children a set of solid values around which to build their lives. This means teaching them to respect the rights and opinions of others; it means respecting elders, teachers, and the law. The best way to teach such values is by example. A child who is lied to will lie. A child who sees his parents steal tools from the factory or towels from a hotel will think that it is all right to steal. A youngster who sees no laughter and no love in the home will have a difficult time laughing and loving.No child asks to be born. If you bring a life into the world, you owe the child something. And if you give him his due, he’ll have something of value to pass along to your grandchildren.39. Which of the following ways is advised for pare ntsto show love to their children?A. Saying “Yes” to everything the children ask for.B. Never embracing older children.C. Refusing something to their children.D. Never criticizing children.40. Which of the following statements is true according to the passage?A. Parents prefer to let their children be in chargeof their own lives at an early age.B. Children learn much by seeing what their parents do.C. Children shouldn’t be corrected because it destroys their self-esteem.D. It is better to compare a youngster to hisbrighter brothers because it makes him tryharder.Part ⅢVocabulary and Structure (20 %) Directions: There are 20 incomplete sentences in this part.

You should decide on the best choice and mark the corresponding letter on the Answer Sheet.Passage 1We have saved as a final set of emotions（情感）the two most important emotions connected with other people: love and its opposite, hate. Love can be seen everywhere. Yet surprisingly, love has been the subject of less scientific research than other emotions, such as anger and fear. The reason for this may be twofold. First, love is a very complex（复杂）emotion, difficult to describe and measure. Secondly, unlike many radical emotions, radical love is generally not a problem; thus less medical attention has been paid to it.What is love? This is a complex question and requires a complex answer. Love is a strong, positive attraction and feeling for another person or thing. But it is more than this. It also involves feeling of caring, protection, excitement, and tenderness（温和）. When two people are in love, they feel drawn to one another; they greatly enjoy each other’s company; and they may be sexually attracted to one another.Sometimes it is easier to think in terms of different kinds of love: romantic love, brotherly love, and so forth. Though they are different in so me respects, they share one important characteristic: astrong positive feeling toward another.Our feelings toward other people are often complex. We may love someone and, at the same time, be angry with him. Or we may love someone, even though we are jealous of him. We might even love someone and, at the same time, hate for some precise reason.Hate is a strong negative emotion toward someone, and is due to anger, jealousy, or some other factor. Like love, hate can be a very strong emotion. It can also be very dangerous. The question is often asked, “Is it bad to hate?” The best answer is probably “sometimes yes and sometimes no.” Usually hate does not help us; it makes us feel unhappy and makes us do things that may hurt others. However, sometimes i t may be necessary to hate and hurt someone in order to protect loved ones.21. The word “saved” in the first sentence of this passage means .A. leftB. relaxedC. set freeD. kept up22. Love is a lasting, strong, positive attraction andfeeling for another person or thing, the very opposite emotion of which is .A. angerB. fearC. jealousyD. hate23. Which characteristic is shared by different kinds of love?A. A strong negative emotion toward someone.B. A strong positive feeling toward another.C. Unhappy feeling toward someone.D. Jealous feeling toward someone.24. According to the passage, hate is caused by .A. anger, jealousy or some other factorsB. anger, danger and hurtC. caring, protection, excitement and tendernessD. complex, strong positive emotion25. Which of the following is true?A. Love has been the subject of less scientificresearch because it is too simple an emotion.B. Radical love is so difficult to describ e andmeasure that less medical attention has beenpaid to it.C. To hate is always too bad.D. We can have at the same time two opposite feelings for another.Passage 2Each Indian（印第安人）was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates（游戏伙伴）would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometime s a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.The Indian earned his real name when he was old。
