The usual explanation is that there is something embeded in every culture-----that dancing is a “cul tural universal”. A researcher in Manchester thingks the impulse may be more deeply rooted than that.He says it may be a reflex reaction.Neil Todd,a psychologist at the University of Manchester. told the BA that he first got an inkling that biology was the key after watching people dance to deafeningly loud music.“There is a compulsion about it.”he says.He reckoned there might be a more direct,biological,explanation for the disre to dance,so he started to look at the inner ear.The human ear has two main functions:hearing and maintaining balance.The standard view is that these tasks are segregated so that organs for balance,for insance,do not have an acoustic function.But Todd says animal studies have shown that the sacculus,which is part of the balance---regulating vestibular system,has retain some sensitivity to sound.The sacculus is especially sensitive to extremely loud noise,above 70 decibel.“There’s no question that in a contemporary dance environment,the sacculus will be stimulated.”says Todd.The av erage rave,he says,blares music at a painful 110 to 140 decibels.But no one really knows what an acoustically stimulated sacculus does.Todd speculates that listening to ex tremely loud music is a form of “vestibular self-stimulation”:it gives a he ightened sensation of motion. “We don’t know exactly why it causes pleasure.”he says.”But we know that people go to extraordinary length to get it.”He list bungee jumping,playing on swings or even rocking to and fro in a rocking chair as other example of pursuits designed to stimulate the sacculus.The same pulsing that makes us feel as though we are moving may make us get up and dances as well,says Todd.Loud music sends signals to the inner ear which may prompt reflex movement. “The typical pulse rate of dance musi c is around the rate of locomo tion.”he says,“It’s quite possible you’re triggering a spinal reflex.”61.The passage begins with______A. a new explanation of musicB. a cultural universal questionedC. a common psychological abnormalityD. a deep insight into human physical movenents62.What intrigued Todd was ______A.human instinct reflexesB.people’s biological heritagesC.people’s compulsion about loud musicD.the damages loud music wrecks on human hearing63.Todd’s biological e xplanation for the desire to dance refers to_____A.the mechanism of hearing soundsB.the response evoked from the sacculusC.the two main functions performed by the human earD.the segregation of the hearing and balance maintaining function64.When the sacculus is acoustically stimulated,according to Todd_____A.functional balance will be maintained in the earB.pleasure will be arousedC.decibel will shoot upD.hearing will occur65.What is the passage mainly about?A.The human ear does more than hearing than expcted.B.Dancing is capable of heighten the sensation of hearingC.Loud music stimulates the inner ear and generates the urge to danceD.The human inner ear does more to help hear than to help maintain balance.passage 2Have you switch off your compter? How about your television? Your video? Your CD player? And even your coffee percolator? Really switched them off,not just pressed the button on some conrtol panel and left your machine with a telltale bright red light warning you that it is ready to jump back to life at your command?Because if you haven’t,you are one of the guilty people who help pollute the planet.It does’t matter if you’ve joined the neighborhood recycling scheme,conscientiously sorted your garbage and avoided driving to work.You still can’t sleep easy while just one of those little red lights is glowing in the dark.The awful truth is that household and office electrical appliances left on stand-by mode are gobbling up energy,even though they are doing absolutely nothing.Some electronic products-----such as CD players----can use almost as much energy on stand-by as they do when running.Others may use a lot less,but as your video player spend far more hours on stand-by than playing anything,the wastage soon adds up.In the US.alone,idle electronic devices consume enough energy to power cities with the energy needs of Chicago or London----costing consumers around ＄1 billion a year.Power stations fill the atmosphere with carbon dioxide just to do absolutely nothing.Thoughtless design is partly responseble for the waste.But manufactures only get away with desinging products that waste energy this way because consumers are not sensitive enough to the issue,indeed,while recycling has caught the public imagination ,reducing waste has attracted much less attention.But “source reduction”,as the garbage experts like to call the art of not using what you don’t need to use,offers enormous potential for reducing waste of all kinds.With a little intelligent shopping,you can cut waste long before you reach the end of the chain.Packaging remains the big villain.One of the hidden consequences of buying products grown or made all around the world,rather than produced locally,is the huge amount of packaging.To help cut the waste and encourage intelligent manufacturers the simplest trick is to look for ultra-light package.The same arguments apply to the very light but strong plastic bottles that are replacing heavier glass alternatives,thin-walled aluminum cans,and cartons made of composites that wrap up anything drinkable in an ultra-light package.There are hundreds of other tricks you can discuss with colleagues while gathering around the proverbial water cooler—filling up,naturally,your own mug rather than a disposable plastic cup.But you don’t need to go as far as one website which tells you how to give your friends unwrapped Christmas presents.There are limits to source correctness.66. Fron the first two paragraphs,the author implies that______A.hitch has made life easy everywhereB.nobody seems to be innocent in polluting the planetC.recycling can potentially control environmental deteriorationD.everybody is joining the global battle against pollution in one way or another67.The waste caused by household and office electrical appliances on stand-by mode seemsto_____A.be a long-standing indoor problemB.cause nothing but troubleC.get exaggeratedD.go unnoticed68.By idle electronic devices,the author means those appliances_____A.left on stand-by modeB.filling the atmosphere with carbon dioxideed by those who are mot energy-conscioused by those whose words spesk louder than actions69.Ultra-light packaging______A.is expected to reduce American waste bu one-thirdB.is an illustration of what is called “source reduction”C.can make both manufacturers and consumers intelligentD.is a villain of what the garnage experts call “source reduction”70.The conclusion the author is trying to draw is that______A.one person cannot win the battle against pollutionB.anybody can pick up tricks of environmental protection on the webC.noybody can be absolutely right in all the tricks of environmental protectionD.anybody can present or learn a trick of cutting down what is not neededpassage 3You can have too much of a good thing,it seems---at least when it comes to physiotherapy after a stroke. Many doctors believe that it is the key to recovery:exetcising a partially paralyzed limb can help the brain “rewire”itself and replace neural co nnections destroyed by a clot in the brain.But the latest animal experiments suggest that too much exercise too soon after a brain injury can make the damage worse. “It’s something that clinicians are not aware of,”says Timothy Schallert of the University at Austin,who led the research.In some trials,stroke victims asked to put their good arm in a sling---to force them to use their partially paralyzed limb---had made much better recoveries than those who used their good arm. But these patients were treated many months after their strokes.Earlier intervention,Schallert reasoned,should lead to even more dramatic improvements.To test this theory,Schallert and his colleagues placed tiny casts on the good forelimbs of rats for two weeks immediately after they were given a small brain injury that partially paralyzed one forelimb.Several weeks later, the researchers were astonished to find that brain tissue surruouding the original injury had also died. “The size of the injury doubled. It’s very dramatic effect.”says Schallert.Brain-injured rats that were not forced to overuse their partially paralyzed limbs showed no similar damage,and the casts did not cause a dramatic loss of brain tissue in animals that had not already suffered minor brain damage.In subsequent experiments,the researchers have found that the critical period for exercise-induced damage in rats is the first week after the initial brain injury.The spreading brain damage witnessed by Schaller’s team was probably caused by the releaseof glutamate,a neurotransmitter,from brain cells stimulated during limb movement.At high doses,glutamate is toxic even to healthy nerve cells.And Schallert believes that a brain injury makes neighboring cells unusually susceptible to the neurotransmitter’s toxic effects.Randolph Nudo of the University of Texas Health Science Center at Houston,who studies brain injury in primates,agrees that glutamate is the most likely culprit.In experiments with squirrel monkeys suffering from stroke-like damage,Nudo tried beginning rehabilitation within five days of injury.Although the treatment was bebeficial in the long run,Nudo noticed an initial worsening of the paralysis that might also have been due to brain damage brought on by exercise.Schallert stresses that mild exercise is likely to be beneficial however soon it begins.He adds that it is unclear whether human victims of strokes,like brain -injured rats,could make their problems worse by exercising too vigorously,too soon.Some clinics do encourage patients to begin physiotherapy within a few weeks of suffering a traumatic head injury or stroke,says David Hovda,director of brain injury research at the University of California,Los Angeles.But even if humans do have a similar period of vulnerability to rat,he speculates that it might be possible to use drugs to block the effects of glutamate.71. Schallert issued a warning to those who____A.believe in the possibility of rewiring the brainB.are ignorant of physiotherapy in the clinicC.add exercise to partially paralyzed limbsD.are on the verge of a stroke72.Which of the following is Schallert’s hypothesis for his investigation.?A.Earlier intervention should lead to even more dramatic improvements.B.The critical period for braim damage is one week after injury.C.A partially paralyzed limb can cause brain damagesD.Physiotherapy is the key to brain recovery.73.The results from Schallert’s rese arch____A.reinforced the singificance of physiotherapy after a strokeB.indicated the fault with his experiment designC.turned out the oppsiteD.verified his hypothesis74.The results made Schallert’s team aware of the fact that____A.glutamate can have toxic efforts on healthy nerve cellsB.exercise can boost the release of glutamateC.glutamate is a neurotransmitterD. all of the above75.Schallert would probably advise clinicians____A.to administer drugs to blick the effects of glutamateB.to be watchful of the amount of exercise for stroke victimsC.to prescribe vigorous exercise to stroke vivtims one week after injuryD.to reconsider the significance of phusiotherapy to brain damagePssage FourOur understanding of cities in anything more than casual terms usually starts with observationsof their spatial form and structure at some point or cross-section in time.This is easiest way to begin,for it is hard to assemble data on how cities change through time,and, in any case,our perceptions often betray us into thinking of spatial structures as being resilient and long lasting.Even where physical change is very rapid,this only has an impact on us when we visit such places infrequent －ly ,after years away. Most of our urban theory,whether it emanates from the social sciences or engineering,is structured around the notion that spatial and spatial and social structures change slowly,and are sufficiently inert for us to infer reasonable explanations from cross-sectional studies.In recent years,these assumptions have come to be challenged,and in previous editorials I have argued the need for a more temporal emphasis to our theories and models,where the emphasis is no longer on equilibrium but on the intrinsic dynamics of urban change.Even these views,however,imply a conventional wisdom where the real focus of urban studies is on processes that lead to comparatively slow changes in urban organization,where the functions determining such change are very largely routine,accomplished over months or years,rather than any lesser cycle of time.There is a tacit assumption that longer term change subsumes routine change on a day-to-day or hour-basis,which is seen as simply supporting the fixed spatial infrastructures that we perceive cities to be built around .Transportation modeling,for example,is fashioned from thes standpoint in that routine trip-making behavior is the focus of study,its explanation being central to the notion that apatial structures are inert and long lasting.76.We ,according to the passage,tend to observe citiesA.chronologicallyB.longitudinallyC.sporadicallyD.horizontally77.we think about a city as____A.a spatial eventB.a symbolica worldC.a social environmentD.an intertelated system78.Cross-sectional studies show that cities ____A.are structured in three dimensiosB.are transformed rapidly in any aspectC.are resilient and long lasting rhrougy timeD.change slowly in spatial and social structrues79.The author is drawing our attention to ____A.the equilibrium of urban spatial structuresB.the intrinsic dynamics of urban changeC.the fixed spatial infrastructureD.all of the above80.The conventional notion,the aurhor contends,____A.presents the inherent nature of a cityB.underlies the fixed spatial infrastructuresC.places an emphasis on lesser cycles of timeD.hinders the physical change of urban structurePassane fiveWhen it is sunny in June,my father gets in his first cutting of hay.He starts on the creek meadows,which are flat,sandy,and hot.They are his driest land.This year,vacationing from my medical practice,I returned to Vermont to help with the haying.The heft of a bale through my leather gloves is familiar:the tautness of the twine,the heave ofthe bale,the sweat rivers that run through the hay chaff on my arms.This work has the smell of sweet grass and breeze.I walk behind the chug and clack of the baler,moving the bales into piles so my brother can do the real work of picking them up later.As hot as the air is,my face is hotter.I am surprised at how soon I get tired.I take a break and sit in the shade,watching my father bale,trying not to think about how old he is,how the heat affects his heart,what might happen.This is not my usual work,of course.My usual work is to sit with patients and listen to them.Occasionslly I touch them,and am glad that my hands are soft.I don’t think my patients would like farmer callouses and dirty hands on their tender spots.Reluctantly I feel for lumps in breasts and testicles,hidden swellings of organs and joints,and probe all the painful places in my patients’lives.There are many,Perhaps I am too soft,could stand callouses of a different sort.I feel heavy after a day’s work ,as if my pat ients were inside me,letting me carry them.I don’t mean to.But where do I put their stories? The childhood beatings,ulcers from stress, incapacitating depression,fears,illness? These are not my experiences,yet I feel them and carry them with me.Try to find healthier meanings,I spent the week before vacation crying.The hay field is getting organized.Piles of three and four bales are scattered around the field.They will be easy to pick up.Dad climbs,tired and lame,from the tractor.I hand him a jar of ice w ater,and he looks with satisfaction on his job just done.I’ll stack a few more bales snd maybe drive the truck for my brother.My father will have some appreciative customers this winter,as he sells his bales of hay.I’ve needed to feel this heaviness in my muscles,the heat on my face.I am taunted by the simplicity of this work,the purpose and results,the definite boundaries of the fields,the dimensions of the bales,for illness is not defined by the boundaries of bodies;it spills into families ,homes, schools,and my office,like hay tumbling over the edge of the cutter bar.I feel the rough stubble left in its wake.I need to remember the stories I’ve helped reshape,new meanings stacked against the despair of pain,I need to remember the smell of hay in June.81.Which of the following is NOT true according to the story?A.The muscular work in the field has an emotional impact on the narrator.B.The narrator gets tired easily working in the field.C.It is the first time for the narroator to do hayingD.The narrator is as physician82.In retrospection ,the narrator___A.feels guilty before his father and brotherB.defends his soft hands in a meaningful wayC.hates losing his muscular power before he knows itD.is shamed for the farmer callouses he does not possess83.As a physician,the narrator is ___A.empathicB.arrogantC.callousD.fragile84.His associations punctuate_____A.the similarities between medicine and agricultureB.the simplicity of muscular workC.the hardship of life everywhereD.the nature of medical practice85.The narrator would say that____A.it can do physicians good to spend a vacation doing muscular workB.everything is interlinked and anything can be anythingC.he is a shame to his fatherD.his trip is worth itPassage SixEveryone has seen it happen,A colleague who has been excited,involved,and productive slowly begins to pull back,lose energy and interest,and becomes a shadow or his or her former self.Or,a person who has been a beacon of vision and idealism retreats into despair or cynicism.What happened? How does someone who is capable and committed become a person who functions minimally and does not seem to care for the job or the people that work there?Burnout is a chronic state of depleted energy ,lack of commitment and involvement,and continual frustration,often accompanied at work by physical symptoms,disability claims and performance problem.Job burnout is a crisis of spirit,when work that was once exciting and meaningful becomes deadening. An organization’s mo st valuable resource---the energy ,dedication,and creativity of its employees---is often squandered by a climate that limits or frustrates the pool of talent and energy available.Milder forms of burnout are a problem at every level in every type of work.The burned-out manager comes to work,but he brings a shell rather than a person.He experiences little satisfaction,and feels uninvolved,detached,and uncommitted to his work and co-workers.While he may be effective by external standards,he works far below his own level of productivity. The people around him are deeply affected by his attitude and energy level,and the whole community begins to suffer.Burnout is a crisis of the spirit because people who burn out were once on fire.It’s especially scary …………….some of the most talented .If they can’t maintain their fire,others ask who can? Are these people lost forever,or can the inner flame be rekindled? People often feel that burnout just comes upon them and that they are helpless victims of it.

武汉大学2004年博士研究生入学考试试题Part ⅠReading Comprehension (30%)Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets.Questions 1 to 5 are based on the following passage:All types of stress study, whether under laboratory or real-life situations, study mechanisms for increasing the arousal level of the brain.The brain blood flow studies show that reciting the days of the week and months of the year increases blood flow in appropriate areas, whereas problem solving which demands intense concentration of a reasoning type produces much larger changes in the distribution of blood in the brain.Between these basic studies of brain function and real life situations there is still a considerable gap, but reasonable deduction seems possible to try and understand what happens to the brain. Life consists of a series of events which may be related to work or to our so-called leisure time. Work may be relatively automatic—as with typing, for instance, it requires intense concentration and repetition during the learning phase to establish a pattern in the brain. Then the typist's fingers automatically move to hit the appropriate keys as she reads the words on the copy. ？However, when she gets tired she makes mistakes much more frequently. To overcome this she has to raise her level of arousal and concentration but beyond a certain point the automatic is lost and thinking about hitting the keys leads to more mistakes.Other jobs involve intense concentration such as holding bottles of wine up to a strong light and turning them upside down to look for particles of dirt falling down. This sounds quite easy but experience teaches that workers can do this for only about thirty minutes before they start making a mistake. This is partly because the number of occasions with dirt in the bottle is low and the arousal level, therefore, fails. Scientists have shown that devices to raise arousal level will increase the accuracy of looking for relatively rare events. A recent study of the effect of loss of sleep in young doctors showed that in tests involving a challenge to their medical judgment when short of sleep they raised their arousal level and became better at tests of grammatical reasoning as well.1. According to the brain blood flow studies, problem solving ________.A. increases blood flow in some areas of the brainB. causes changes in the distribution of blood in the brainC. demands intense concentration of blood in certain areasD. is based on the ability to recite the time2. The author believes that ________.A. the results obtained in the laboratory exactly reflects the real-life situationsB. the gap between the laboratory studies and real-life situations is too large to fill upC. the gap between the laboratory studies and real-life situations can be closed by proper reasoningD. the difference between the laboratory studies and real-life situations will be reduced3. When a typist gets tired, ________.A. she has to try hard to raise her automaticB. she can type only automaticallyC. she cannot think about what she is doing.D. she can seldom type automatically4. Examining bottles of wine is hard work because ________.A. the bottles must be held upside downB. it is difficult to see the particles of dirt？C. it requires high level of automaticD. most bottles are all right5. According to the author, a key factor in the ability to reason is ________. ？？？？？？A. the subject's knowledge of grammarB. the amount of sleep the subject has hadC. the level of arousal of the subjectD. the extent to which the subject has been taught to reasonQuestions 6 to 10 are based on the following passage:Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer bangs a small hammer on a table at which he stands. This is often set on a raised platform called a rostrum. ？The ancient Romans probably invented sales by auction, and the English word comes from the Latin auctio, meaning “increase”. The Romans usually sold in this way the spoils taken in war; these sales were called sub basra, meaning “under the spear”, a spear being stuck in the ground as a signal for a crowd to gather. In England in the eighteenth and nineteenth centuries goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.Practically all goods whose qualities vary are sold by auction. Among these are coffee, hides, skins, wool, tea, cocoa, furs, spices, fruit and vegetables and wines. Auction sales are also usual for land and property, antique furniture, pictures, rare books, old china and similar works of art. The auction rooms at Christie's and Sotheby's in London and New York are world famous.An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by prospective buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold？together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in numerical order; he may wait until he registers the fact that certain dealers are in the room and then produce the lots they are likely to be interested in. The auctioneer's services are paid for in the form of a percentage of the price tha goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible.The auctioneer must know fairly accurately the current market values of the goods he is selling, and he should be acquainted with regular buyers of such goods. He will not waste time by starting the bidding too low. He will also play on the rivalries among his buyers and succeed in getting a hight price by encouraging two business competitors to bid against each other. It is largely on his advice that a seller will fix a “reserve” price, that is ,a price below which the goods cannot be sold. Even the best auctioneers, however, find it difficult to stop a “knock out”, whereby dealers illegally arrange beforehand not to bid against each other, but nominate one of themselves as theonly bidder, in the hope of buying goods at extremely low prices. If such a “knock-out” comes off ,the real auction sale takes place privately afterwards among the dealers.6. A candle used to burn at auction sales ________.A. because they took place at nightB. as a signal for the crowd to gatherC. to keep the auctioneer warmD. to limit the time when offers could be made7. An auction catalogue gives prospective buyers ________.A. the current market values of the goodsB. details of the goods to be soldC. the order in which goods must be soldD. free admission to the auction sale8. The auctioneer may decide to sell the “lots” out of order because ________. ？？A. he sometimes wants to confuse the buyersB. he knows from experience that certain people will want to buy certain itemsC. he wants to keep certain people waitingD. he wants to reduce the number of buyers9. An auctioneer likes to get high prices for the goods he sells because ________.A. then he earns more himselfB. the dealers are pleasedC. the auction-rooms become world famousD. it keeps the customers interested10. A “knock out”？is arranged ________.A. to keep the price in the auction room lowB. to allow one dealer only to make a profitC. to increase the auctioneer's profitD. to help the auctioneerQuestions 11 to 15 are based on the following passage:Whenever two or more unusual traits or situations are found in the same place, it is tempting to look for more than a coincidental relationship between them. The high Himalayas and the Tibetan plateau certainly have extraordinary physical characteristics and the cultures which are found there are also unusual, though not unique. However there is no intention of adopting Montesquieu's view of climate and soil as cultural determinants. The ecology of a region merely poses some of the problems faced by the inhabitants of the region, and while the problems facing a culture are important to its development, they do not determine it.？The appearance of the Himalayas during the late Tertiary Period and the accompanying further raising of the previously established rages had a marked effect on the climate of the region. Primarily, of course, it blocked the Indian monsoon (季风) from reaching Central Asia at all. Secondarily, air and moisture from other？？Directions were also reduced.Prior to the raising of the Himalayas, the land now forming the Tibetan uplands had a dry, continental climate with vegetation and animal life similar to that of much of the rest of the region on the same parallel, but somewhat differen than that of the areas farther north, which were already drier. With the coming of the Himalayas and the relatively sudden drying out of the region, there was a severe thinning out of the animal and plant population. The ensuing incompletePleistocene glaciations (冰蚀) had a further thinning effect, but significantly did not wipe out life in the area. Thus after the end of the glaciation there were only a few varieties of life extant from the original continental species. Isolated by the Kunlun range from the Tarim basin and Turfan depression, species which had already adapted to the dry steppe climate, and would otherwise have been expected to flourish in Tibetan, the remaining native fauna and flora (动植物) multiplied. Armand describes the Tibetan fauna as not having great variety, but being “striking” in the abundance of the particular species that are present. The plant life is similarly limited in variety, with some observers finding no more than seventy varieties of plants in even the relatively fertile Eastern Tibetan valleys. with fewer than ten food crops. Tibetan “tea” is a major staple, perhaps replacing the unavailable vegetables.The difficulties of living in an environment at once dry and cold. and populated with species more usually found in more hospitable climates, are great. These difficulties may well have influenced the unusual polyandrous (一妻多夫制) societies typical of the region. Lattimore sees the maintenance of multiple-husband households as being preserved from earlier forms by the harsh conditions of the Tibetan uplands, which permitted no experimentation and “froze” the cultures which came there. Kawakita, on the other hand, sees the polyandry as a way of easily permitting the best householder to become the head husband regardless of age. His detailed studies of the Bhotea village of Tsumje do seem to support this idea of polyandry as a method of talent mobility is a situation where even the best talent is barely enought for survival.In sum, though arguments can be made that a pre-existing polyandrous system was strengthened and preserved (insofar as it has been) by the rigors of the land, it would certainly be an overstatement to lay causative factors of any stronger nature to the ecological influences in this case.11. What are the “unusual traits or situations” referred to in the first sentence?A. Patterns of animal and plant growth.B. Food and food preparation patterns of the upland Tibetans.C. Social and familial organization of typical Tibetan society.D. All of the above.12. The purpose of the passage is to ________.A. analyze the possible causal links between Tibetan ecology and societyB. describe the social organization of typical Tibetan villagesC. describe Tibetan fauna and floraD. analyze the mysteries of the sudden appearance of the Himalayas13. The author 's knowledge of Tibet is probably ________.A. based on firsthand experienceB. the result of lifelong studiesC. derived from books onlyD. limited to geological history14. According to the passage, which of the following would probably be the most agreeable to Montesquieu?A. All regions have different soils and thus, different cultures.B. some regions with similar climates will have similar cultures.C. Cultures in the same area, sharing soil and climate, will be essentially identical.D. The plants of a country, by being the food of its people, cause the people to have similar viewsto one another.15. The species of fauna and flora remaining in Tibet after the Pleistocene glaciation can properly be called continental because they ________.A. are originally found in continental climatesB. are the only life forms in Tibet, which is as big as a continentC. have been found in other parts of the Asian continentD. are found in land mass that used to be a separate continentQuestions 16 to 20 are based on the following passage:Opponents of affirmative action say the battle over the use of race in college admissions is hardly over, despite the Supreme Court's ruling Monday upholding the goal of a diverse student body. Higher education leaders overwhelmingly hailed the decision, saying it reaffirmed policies used by most selective colleges and universities. But some critics raised the possibility of more lawsuits, and promised to continue pressuring the Department of Education's Office of Civil Rights to investigate questionable policies.“We're talking about admissions programs, scholarships, any program...only for minorities or in which the standards used to judge admissions are substantially different,” says Linda Chavez, founder and president of the Center for Equal Opportunity, a conservative non-profit group.Others say they'll take their case to voters. “We have to seriously contest all this at the ballot box,” says University of California regent Ward Cannerly, who helped win voter approval of California's Proposition 209, which prohibits considering race or gender in public education, hiring and contracting. Because of that law, Monday's ruling had no practical impact in the state. “It may be time for us to...let the (Michigan) voters decide if they want to use race as a factor in admissions,” Connerly said Monday.Meanwhile, U. S. Education Secretary Rod Paige, consistent with President Bush's stance opposing affirmative action, said the Department of Education will “continue examining and highlighting effective race-neutral approaches to ensure broad access to and diversity within our public institutions”. Even Supreme Court Justice Sandra Day O' Connor, in one of the opinions, recommended that states look for lessons in race-neutral programs being tried in California and elsewhere. While the ruling said admissions officials may consider race in the selection process, colleges and universities are not obligated to do so. “Ultimately in the debate, diversity is a choice, not a legal mandate,” says Arthur Coleman, a former Department of Education official who now helps colleges and universities ensure constitutional policies.The public, too, remains conflicted, largely along racial lines. According to a january poll by the non-profit research organization Public Agenda, 79% of Americans said it is important for colleges to have a racially diverse student body, while just 54% said affirmative action programs should continue. In a Gallup poll conducted days before the ruling, 49% of adults said they favor affirmative action and 43% did not, with blacks and Hispanics far more likely to favor the practice than whites. And some educators doubt that with Monday's ruling, those opposing affirmative action will change their minds.For now, admissions officials and university lawyers are poring over the ruling to determine how or whether to adjust policies. While most tend to be closed-mouthed about admissions policies, many say they don't expect significant changes.16. What the critics said in the first paragraph amounts to the idea that ________.A. no admission policies based on race should be implemented.B. minority applicants should be given favorable considerations.C. different standards for admitting minority students should be set up.D. selective colleges and universities should be punished for their discriminatory policies.17. Connerly insists that the Court's ruling should ________.A. win approval from Californian voters before it is put in effectB. be contested by the Michigan voters with an opinion pollC. be applied in some states before it is extended to other statesD. produce the intended practical effect before it is widely accepted18. What is the attitude of the Department of Education towards affirmative action?A. NeutralityB. ObjectionC. ApprovalD. Indifference19. Which of the following is True about affirmative action according to the text?A. A vast majority of people support it.？B. The minorities claim it to be a discriminatory policy.C. The minority students are more likely to welcome it.D. the Court's decision will certainly change people's attitude to it.20. It can be inferred from the text that one of the major objectives of affirmative action is to ________.A. ensure race-neutral programs are set up in college and universitiesB. adapt the Supreme Court's ruling to college situationsC. formulate the right policies for college admissionsD. discourage the practice of racial discrimination in college admissionsPart ⅡEnglish-Chinese Translation (25%)？Directions: Read the following passage carefully and then translate the underlined sentences into Chinese.Computers are permeating almost every aspect of our lives, including many areas previously untouched by technology. 1. But unlike such other pervasive technologies as electricity, television and the motor car, computers are on the whole less reliable and less predictable in their behavior. This is because they are discrete state digital electronic devices that are prone to total and catastrophic failure. Computer systems, when they are “down,” are completely down, unlike electromechanical devices, which may be only partially down and are thus partially usable. Computers enable enormous quantities of information to be stored, retrieved, and transmitted at great speed on a scale not possible before. 2. This is all very well, but it has serious implications for data security and personal privacy because computers are inherently insecure. The recent activities of hackers and data thieves in the United States, Germany, and Britain have shown how all-too-easy it still is to break into even the most-sophisticated financial and military systems. The list of scares perpetrated by the new breed of hi-tech criminals, ranging from fraud in airline-ticket reservations to the reprogramming of the chips inside mobile phones, is growing daily. Computer systems are often incredibly complex-so complex, in fact, that they are not always understood even by their creators (although few are willing to admit it). This often makes them completely unmanageable. Unmanageable complexity, can result in massive foul-ups or spectacular budget “runaways.” For example, Jeffrey Rothfeder in Business Week reports thatBank of America in 1988 had to abandon a $ 20-million computer system after spending five years and a further $ 60 million trying to make it work. Allstate Insurance saw the cost of its new system rise from $ 8 million to a staggering $ 100 million and estimated completion was delayed from 1987 to 1903. Moreover, the problem seems to be getting worse: in 1988 the American Arbitration. Association took on 190 computer disputes, most of which involved defective systems. The claims totaled 200m i l l i o n—up from only $ 31 million in 1984.3. Complexity can also result in disaster: no computer is 100 percent guaranteed because it is virtually impossible to anticipate all sorts of critical applications, such as saving lives, flying air craft, running nuclear power stations, transferring vast sums of money, and controlling missile systems—sometimes with tragic consequences. For example, between 1982 and 1987, some twenty-two servicemen died in five separate crashes of the United States Air Force's sophisticated Blackhawk helicopter before the problem was traced to its computer-based “fly-by-wire” system. At least two people died after receiving overdoses of radiation emitted by the computerized. There are 25 X-ray machines, and there are many other examples of fatal computer-based foul-ups. Popular areas for less life-threatening computer malfunctions include telephone billing and telephone switching software, bank statements and bank-teller machines, electronic funds-transfer systems, and motor-vehicle license data bases. Although computers have often taken the “blame” on these occasions, the ultimate cause of failure in most cases is, in fact, human error.Every new technology creates new problems—as well as new benefits--for society, and computers are no exception. 4. But digital computers have rendered society especially vulnerable to hardware and software malfunctions. Sometimes industrial robots go crazy, while heart pacemakers and automatic garage door openers are rendered useless by electromagnetic radiation or “electronic smog” emitted from point-of-sale terminals, personal computers, and video games. Automated teller machines (ATMs) and pumps at gas stations are closed down because of unforeseen software snafus.The cost of all this downtime is huge. 5. For example, it has been reported that British businesses suffer around thirty major mishaps a year. revolving losses running into millions of pounds. These are caused by machine or human error and do not include human misuse in the form of fraud and sabotage. The cost of failures in domestically produced software in the United Kingdom alone is conservatively estimated at $ 900 million per year. In 1989, a British Computer Society committee, reported that much software was now so complex that current skills in safety assessment were inadequate and that therefore the safety of people could not be guaranteed.Part Ⅲ？？Chinese-English Translation (25%)？Directions: Translate the following short paragraph into English and write your translation on the ANSWER SHEET.1. 一位负责扶贫工作的官员说，到２００４年底，尽管大多数贫困人口将解决温饱问题，还将有一些生活极端贫困的人们，他们还需要政府的资助。
