医学考博英语特训教材阅读1试题English:The paragraph discusses the concept of immunological memory, which is a fundamental aspect of the adaptive immune response. Immunological memory refers to the ability of the immune system to remember previously encountered pathogens and mount a faster and more robust response upon re-exposure. This phenomenon is primarily mediated by memory T and B cells, which are generated during the initial infection or vaccination. Memory T cells are capable of recognizing specific antigens presented by infected cells, while memory B cells produce antibodies that can bind to and neutralize pathogens. The paragraph highlights the importance of immunological memory in providing long-lasting protection against infectious diseases and the basis for vaccination strategies. It also emphasizes the role of memory cells in secondary immune responses, which are quicker and more effective due to the presence of pre-existing memory cells. Overall, immunological memory is crucial for the effectiveness of the adaptive immune system in combating recurring infections and is a cornerstone of immunology research and vaccine development.中文翻译:该段讨论了免疫记忆的概念，这是适应性免疫应答的基本方面。

At least, that is what most men are convinced of. Psychologists view the subject either as a matter of frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse.There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes —the link between the two halves of the brain.The two halves are linked by a trunk line of between 200 and 300 million nerves, the corpus callosum (胼胝体). Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibers than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is "What?", and, if this difference exists, are there others? Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution? We tend to think that is the influence of society that produces these differences. But could we be wrong?Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for word-handing, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections.But it isn"t all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at "language subjects" and boys better at maths and physics. If these differences correspond with the differences in the hemispheric trunk line, there is an unalterable distinction between the sexes.We shan"t know for a while, partly because we don"t know of any precise relationship between abilities in school subject and the functioning of the two halves of the brain, and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.（分数：5.00）(1).Which of the following statement is CORRECT?（分数：1.00）A.Biologists are conducting research where psychologists have given up.B.rain differences point to superiority of one sex over the other.C.Results of scientific research fail to support popular belief.D.The structural difference in the brain between the sexes has long been known.(2).According to the passage it is commonly believed that brain differences are caused by ______ factors.（分数：1.00）A.biologicalB.psychologicalC.physicalD.social(3)."These differences" in paragraph 5 refer to those in ______.（分数：1.00）A.skills of men and womenB.school subjectsC.the brain structure of men and womenD.activities carried out by the brain(4).At the end of the passage the author proposes more work on ______.（分数：1.00）A.the brain structure as a wholeB.the functioning of part of the brainC.the distinction between the sexesD.the effects of the corpus callosum(5).What is the main purpose of the passage?（分数：1.00）A.To outline the research findings on the brain structure.B.To explain the link between sex and brain structure.C.To discuss the various factors that cause brain differences.D.To suggest new areas in brain research.十三、Passage Two(总题数：1，分数：5.00)Can electricity cause cancer? In a society that literally runs on electric power, the very idea seems preposterous. But for more than a decade, a growing band of scientists and journalists has pointed to studies that seem to link exposure to electromagnetic fields with increased risk of leukemia and other malignancies. The implications are unsettling, to say the least, since everyone comes into contact with such fields, which are generated by everything electrical, from power lines and antennas to personal computers and micro-wave ovens. Because evidence on the subject is inconclusive and often contradictory, it has been hard to decide whether concern about the health effects of electricity is legitimate—or the worst kind of paranoia.Now the alarmists have gained some qualified support from the U.S. Environmental Protection Agency. In the executive summary of a new scientific review, released in draft form late last week, the EPA has put forward what amounts to the most serious government warning to date. The agency tentatively concludes that scientific evidence "suggests a casual link" between extremelylow-frequency electromagnetic fields—those having very longwave-lengths—and leukemia, lymphoma and brain cancer, While the report falls short of classifying ELF fields as probable carcinogens, it does identify the common 60-hertz magnetic field as "a possible, but not proven, cause of cancer in humans".The report is no reason to panic—or even to lost sleep. If there is a cancer risk, it is a small one. The evidence is still so controversial that the draft stirred a great deal of debate within the Bush Administration, and the EPA released it over strong objections from the Pentagon and the White House. But now no one can deny that the issue must be taken seriously and that much more research is needed.At the heart of the debate is a simple and well-understood physical phenomenon: When an electric current passes through a wire, it generates an electromagnetic field that exerts forces onsurrounding objects. For many years, scientists dismissed any suggestion that such forces might be harmful, primarily because they are so extraordinarily weak. The ELF magnetic field generated by a video terminal measures only a few milligauss, or about one-hundredth the strength of the earth"s own magnetic field. The electric fields surrounding a power line can be as high as 10 kilovolts per meter, but the corresponding field induced in human cells will be only about 1 millivolt per meter. This is far less than the electric fields that the cells themselves generate. How could such minuscule forces pose a health danger? The consensus used to be that they could not, and for decades scientists concentrated on more powerful kinds of radiation, like X-rays, that pack sufficient wallop to knock electrons out of the molecules that make up the human body. Such "ionizing" radiations have been clearly linked to increased cancer risks and there are regulations to control emissions.But epidemiological studies, which find statistical associations between sets of data, do not prove cause and effect. Though there is a body of laboratory work showing that exposure to ELF fields can have biological effects on animal tissues, a mechanism by which those effects could lead to cancerous growths has never been found.The Pentagon is far from persuaded. In a blistering 33-page critique of the EPA report, Air Force scientists charge its authors with having "biased the entire document" toward proving a link. "Our reviewers are convinced that there is no suggestion that electromagnetic fields present in the environment induce or promote cancer," the Air Force concludes. "It is astonishing that the EPA would lend its imprimatur on this report." Then Pentagon"s concern is understandable. There is hardly a unit of the modem military that does not depend on the heavy use of some kind of electronic equipment, from huge ground-based radar towers to the defense systems built into every warship and plane.（分数：5.00）(1).The main idea of this passage is ______.（分数：1.00）A.studies on the cause of cancerB.controversial view-points in the cause of cancerC.the relationship between electricity and cancerD.different ideas about the effect of electricity on caner(2).The view-point of the EPA is ______.（分数：1.00）A.there is casual link between electricity and cancerB.electricity really affects cancerC.controversialD.low frequency electromagnetic field is a possible cause of cancer(3).Why did the Pentagon and White House object to the release of the report? Because ______.（分数：1.00）A.it may stir a great deal of debate among the Bush AdministrationB.every unit of the modem military has depended on the heavy use of some kind of electronic equipmentC.the Pentagon"s concern was understandableD.they had different arguments(4).It can be inferred from physical phenomenon ______.（分数：1.00）A.the force of the electromagnetic field is too weak to be harmfulB.the force of the electromagnetic field is weaker than the electric field that the cells generateC.electromagnetic field may affect healthD.only more powerful radiation can knock electron out of human body(5).What do you think ordinary citizens may do after reading the different arguments?（分数：1.00）A.They are indifferent.B.They are worried very much.C.The may exercise prudent avoidance.D.They are shocked.十四、Passage Three(总题数：1，分数：5.00)Here"s a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn"t eat this and she mustn"t eat that. Oh, but of course, she doesn"t want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it"s the surest way to an early grave. They spend a truly memorable evening together and never see each other again.What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for "health cures". For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don"t think it"s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God. Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they"re always hungry. You can"t be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood is a complete food, the advertisement says. Just dissolve a teaspoonful in water. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they"re always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice!What"s all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!（分数：5.00）(1).The best title for this passage is ______.（分数：1.00）A.On FatB.We Should All Grow Fat and Be HappyC.Many Diseases Are Connected with FatD.Diet Deprives People of Normal Life(2).Why do they never see each other again?（分数：1.00）A.Because it is a memorable evening.B.Because she lets him eat as much fattening food as he wants.C.Because she does not eat this and drink that.D.Because eating fattening food is the surest way to an early grave.(3).What"s the meaning of "lot" in the first line of Paragraph 2?（分数：1.00）A.Amount.B.Field.C.Fate.D.Group.(4).Which of the following ways is NOT mentioned for diet?（分数：1.00）A.Doing exercises.B.Not eating sugar.C.Not eating fat.D.Taking sauna baths.(5).What is the author"s attitude toward diet?（分数：1.00）A.Persuasive.B.Critical.C.Indifferent.D.Adversative.十五、Passage Four(总题数：1，分数：5.00)Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of PhDs. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter of expert guessing. Last week a well-rounded study was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless.The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph.D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates.Discussing the study last week, Dr. Tucker said the project was initiated because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph.D. programs were capable of competing the requirement for the degree. Attrition at the Ph.D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of highly trained specialists and college teachers could be reduced by persuading the dropouts to return to graduate schools to complete the Ph.D. "The results of our research," Dr. Tucker concluded, "did not support these opinions."1. Lack of motivation was the principal reason for dropping out.2. Most dropouts went as far in their doctoral program as was consistent with their levels of ability or their specialities.3. Most dropouts are now engaged in work consistent with their education and motivation. Nearly 75 per cent of the dropouts said there was no academic reason for their decision, but those who mentioned academic reason cited failure to pass the qualifying examination, uncompleted research and failure to pass language exams. Among the single most important personal reasons identified by dropouts for non-completion of their Ph.D. program, lack of finances was marked by 19 per cent.As an indication of how well the dropouts were doing, a chart showed 2% in humanities were receiving $20,000 and more annually while none of the Ph. D."s with that background reached this figure. The Ph. D."s shone in the $7,500 to $15,000 bracket with 78% at that level against 50% for the dropouts. This may also be an indication of the fact that top salaries in the academic fields, where Ph. D."s tend to rise to the highest salaries, are still lagging behind other fields. As to the possibility of getting dropouts back on campus, the outlook was glum. The main condition which would have to prevail for at least 25% of the dropouts who might consider returning to graduate school would be to guarantee that they would retain their present level of income and in some cases their present job.（分数：5.00）(1).The author states that many educators feel that ______.（分数：1.00）A.steps should be taken to get the dropouts back to campusB.the dropouts should return to a lower quality school to continue their studyC.the Ph.D. holder is generally a better adjusted person than the dropoutD.the high dropouts rate is largely attributable to the lack of stimulation on the part of faculty members(2).Research has shown that ______.（分数：1.00）A.dropouts are substantially below Ph. D."s in financial attainmentB.the incentive factor is a minor one in regard to pursuing Ph.D. studiesC.the Ph.D. candidate is likely to change his field of specialization if he drops outD.about one-third of those who start Ph.D. work do not complete the work to earn the degree(3).Meeting foreign language requirements for the Ph. D. ______.（分数：1.00）A.is the most frequent reason for dropping outB.is more difficult for the science candidate than for the humanities candidateC.is an essential part of many Ph.D. programsD.does not vary in difficulty among universities(4).After reading the article, one would refrain from concluding that ______.（分数：1.00）A.optimism reigns in regard to getting Ph. D. dropouts to return to their pursuit of the degreeB.a Ph.D. dropout, by and large, does not have what it takes to learn the degreeC.colleges and universities employ a substantial number of Ph. Ｄ. dropoutsD.Ph. Ｄ."s are not earning what they deserve in nonacademic positions(5).It can be inferred that the high rate of dropouts lies in ______.（分数：1.00）A.salary for Ph.D. too lowB.academic requirement too highC.salary for dropouts too highD.1,000 positions十六、Passage Five(总题数：1，分数：5.00)Avian influenza is an infectious disease of birds caused by type A strains of the influenza virus. The disease, which was first identified in Italy more than 100 years ago, occurs worldwide. All birds are thought to be susceptible to infection with avian influenza, though some species are more resistant to infection than others. Infection causes a wide spectrum of symptoms in birds, ranging from mild illness to a highly contagious and rapidly fatal disease resulting in severe epidemics. The latter is known as "highly pathogenic avian influenza". This form is characterized by sudden onset, severe illness, and rapid death, with a mortality that can approach 100%. Fifteen subtypes of influenza virus are known to infect birds, thus providing an extensive reservoir of influenza viruses potentially circulating in bird populations. To date, all outbreaks of the highly pathogenic form have been caused by influenza A viruses of subtypes H5 and H7. Migratory waterfowl—most notably wild ducks—are the natural reservoir of avian influenza viruses, and these birds are also the most resistant to infection. Domestic poultry, including chickens and turkeys, are particularly susceptible to epidemics of rapidly fatal influenza. Direct or indirect contact of domestic flocks with wild migratory waterfowl has been implicated as a frequent cause of epidemics. Live bird markets have also played an important role in the spread of epidemics.Recent research has shown that viruses of low pathogenicity can, after circulation for sometimes short periods in a poultry population, mutate into highly pathogenic viruses. During a 1983-1984 epidemic in the United States of America, the H5N2 virus initially caused low mortality, but within six months became highly pathogenic, with a mortality approaching 90%. Control of the outbreak required destruction of more than 17 million birds at a cost of nearly US$ 65 million. During a 1999-2001 epidemic in Italy, the H7N1 virus, initially of low pathogenicity, mutated within。

医学考博英语翻译习题An AIDS Mystery Solved(1) About 15 years ago， a well-meaning man donated blood to the Red Cross in Sydney，Australia，not knowing he has been exposed to HIV-1，the virus that causes AIDS. Much later，public-health officials learned that some of the people who got transfusions? containing his blood had become infected with the same virus; presumably they were almost sure to die. But as six years stretched to 10，then to 14，the anxiety of health officials gave way to astonishment. Although two of the recipients have died from other causes，not one of the seven people known to have received transfusions of the man’s contaminated blood has come down with AIDS. More telling still，the donor，a sexually active homosexual，is also healthy. In fact his immune system remains as robust as if he had never tangled with HIV at all. What could explain such unexpected good fortune?(2) A team of Australian scientists has finally solved the mystery. The virus that the donor contracted and then passed on，the team reported last week in the journal Science. contains flaws in its genetic script that appear to have rendered it innocuous?. “Not only have the recipients and the donor not progressed to disease for 15 years，”marvels molecular biologist Nicholas Deacon of Australia’s Macfarlane Burnet Centre for Medical Re-search，“but the prediction is that they never will.”Deacon speculates that this “impotent”HIV may even be a natural inoculant? that protects its carriers against more virulent strains? of the virus，much as infection with cowpox warded off smallpox in 18th-century milkmaids.(3) If this ______ proves right，it will mark a milestone in the battle to contain the late-20th century’s most terrible epidemic. For in addition to explaining why this small group of people infected with HIV has not become sick，the discovery of a viral strain that works like a vaccine would have far-reaching implications. “What these results suggest，”says Dr. Barney Graham of Tennessee’s Vanderbilt University，“is that HIV is vulnerable and that it is possible to stimulate effective immunity against it.”(4) The strain of HIV that popped up? in Sydney intrigues scientists because it contains striking abnormalities in a gene that is believed to stimulate viral duplication. In fact，the virus is missing so much of this particular gene —known as nef，for negative factor —that it is hard to imagine how the gene could perform any useful function. And sure enough，while the Sydney virus retains the ability to infect T cells —white blood cells that are critical to the immune system’s ability to ward off infection —it makes so few copies of itself that the most powerful molecular tools can barely detect its presence. Some of the infected Australians，for example，were found to carry as few as one or two copies of the virus for every 100000 T cells. People with AIDS，by contrast，are burdened with viral loads thousands of times higher.(5) At the very least，the nef gene offers an attractive target for drug developers. If its activity can be blocked，suggests Deacon，researchers might be able to hold the progression of disease at bay，even in people who have developed full-blown AIDS. The need for better AIDS-fighting drugs was underscored last week by the actions of a U.S. Food and Drug Administration advisory panel，which recommended speedy approval of two new AIDS drugs，including the first of a new class of compounds called protease? inhibitors?. Although FDA commissioner David Kessler was quick to praise the new drugs，neither medication can prevent or cure AIDS once it has taken hold.(6) What scientists really want is a vaccine that can prevent infection altogether. And that’s what makes the Sydney virus so promising —and so controversial. Could HIV itself，stripped of nef and adjacent sections of genetic material，provide the basis for such a vaccine，as Deacon and his colleagues cautiously suggest? Ongoing work on SIV，the simian? immunodeficiency virus that causes an AIDS-like illness in monkeys，indicates that this might be less far-fetched than it sounds. Ronald Desrosiers at the New England Regional Primate Re-search Center has demonstrated that when the nef gene is removed from SIV，the virus no longer has the power to make monkeys sick. Moreover，monkeys inoculated? with the nef free SIV developed marked resistance to the more virulent strain.(7) But few scientists are enthusiastic about testing the proposition by injecting HIV —however weakened —into millions of people who have never been infected. After all，they note，HIV is a retrovirus?，a class of infectious agents known for their alarming ability to integrate their own genes into the DNA of the cells they infect. Thus once it takes effect，a retrovirus infection —unlike those of viruses that cause measles，smallpox and any number of others diseases —is permanent. While some retroviruses are benign，others can strike without warning. Some remain hidden for years，only to trigger disease late in life when the immune system starts to decrease.(8) This makes vaccine development extremely risky. A weakened strain of SIV that protected adult monkeys，for example，looked safe until researchers at the Dana Farber Cancer Institute in Boston showed that newborn monkeys with immature immune systems did not respond as healthy adults do. All the young primates，in fact，developed the very disease the weakened virus was supposed to prevent. For this and a host of other reasons，most AIDS researchers argue that the only prudent strategy is to concoct? a hybrid? vaccine，putting the key features of a disabled AIDS virus into something more benign than a retrovirus. Among the leading candidates：the vaccinia virus that successfully wiped out smallpox.(9) A handful of researchers，however，argue that the more dangerous retroviral vaccine should not be written off prematurely. Desrosiers，for one，believes the situation in parts of the developing world (where the chance of HIV infection may reach 40% among sexually active adults) has become so desperate that a retroviral vaccine may be worth the ______. A live vaccine made from HIV，he maintains，can be made safer by removing not just the nef gene but several others as well. Desrosiers has found that he can cripple HIV by chemically deleting four of its nine known genes and still get a virus that replicates，at least in chimpanzees.(10) At present，concerns about safety are so overwhelming that efforts to develop a live retroviral vaccine are unlikely to win much support. But that could change as studies of long-term survivors —that small，charmed circle of people who have been infected with the AIDS virus but have remained disease-free —provide new insights into the weaknesses of the viral enemy and the untapped strengths of its human targets. “These individuals，”observes Dr. Warner Greene，director of the Gladstone Institute of Virology and Immunology in San Francisco，“are natural experiments，and they hold a great secret that we are still trying to decipher?.”Indeed，it is entirely possible that the eight Australians who have caused such a stir will be cited by medical texts as the first people on the planet to be successfully，if accidentally，vaccinated against the AIDS virus —a virus that until now has seemed all but invincible.艾滋之谜揭晓(1) 大约在15年前，澳大利亚悉尼有一位人士好心向红十字会捐血，不知道自己已感染HIV-1型——这是造成艾滋病的病毒。

And too many people are using 1 therapies, even while there are a few treatments that do work. Millions of Americans lie awake at night counting sheep or have a stiff drink or 2 a pill, hoping it will make them sleepy. But experts agree all that self-medicating is a bad idea, and the causes of chronic insomnia remain 3 . Almost a third of adults have trouble sleeping, and about 10 percent have symptoms of daytime 4 that signal true insomnia. But 5 the complaints, scientists know surprisingly little about what causes chronic insomnia, its health consequences and how best to treat it, a panel of specialists brought together by the National Institutes of Health concluded Wednesday. The panel called for a broad range of research into insomnia, 6 that if scientists understood its 7 causes, they could develop better treatments.Most, but not all, insomnia is thought to accompany other health problems, from arthritis and depression to cardiovascular disease. The question often is whether the insomnia came first or was a result of the other diseases and how trouble sleeping 8 complicates those other problems. Other diseases aside, the risk of insomnia seems to increase with age and to be more common among women, especially after their 50s. Smoking, caffeine and numerous 9 drugs also affect sleep. The NIH is spending about $200 million this year on sleep-related research, some 10 to specific disorders and others examining the underlying scientific laws that control the nervous system of sleep. The agency was awaiting the panel"s review before deciding what additional work should be directed at insomnia.（分数：10.00）A.unknownB.improperC.unprovenD.uncertainA.prescribeB.popC.abuseD.experimentA.anonymousB.mysteriousC.unexpectedD.peculiarA.deficiencyB.inefficiencyC.malignancyD.impairmentA.for allB.due toC.in addition toD.in thatA.notingB.notifyingC.nominatingD.denotingA.undertakingB.underliningC.underminingD.underlyingA.in shortB.in essenceC.in turnD.in caseA.subscriptionB.ascriptionC.conscriptionD.prescriptionA.targetedB.designatedC.aimedD.designed十一、PartⅣ Reading Compre(总题数：0，分数：0.00)十二、Passage One(总题数：1，分数：5.00)Some problems can be readily identified simply by looking around. These problems concern the pollution of our environment by technology as a result of sudden upsets in the physical, economic and social balance. The most obvious of these are the general pollution of our physical environment and the destruction of irreplaceable natural resources. Not so obvious as these, but just as painfully significant to some, are the disappearing and changing of jobs which overnight often create large groups of jobless citizens.Can technology be used to undo what it has done, replace what it has destroyed or substitute for what it has caused to disappear? No one knows. Many wonder whether or not all of the sources of pollution have yet been identified, whether or not they are being arrested and whether or not they will be prevented from recurring.Another set of problems relates to what technological advancement has done to the quality of life. An improved social life has not been unfortunately, either the goal or the chief beneficiary of technological change. Rather, any improvements that have occurred have been more accidental than intended. Too much has happened too fast. The changes demanded of marriage and family relationships remain largely unexamined. It is often a matter of "put up or shut up", and a person has to adapt his life-style to ever-changing conditions with little time for choice. The"no-move-no-advancement" type is an example of one such problem. Many people are coming to think that the reward is simply not worthy the struggle, and they are taking jobs with less responsibility and lower pay.（分数：5.00）(1).In the First paragraph the author is mainly talking about ______.（分数：1.00）A.environmental protectionB.environment and technologyC.technology producing obvious and insidious problemsD.the advantages and disadvantages of technology(2).According to the passage, no one knows whether or not technology ______.（分数：1.00）A.will solve the problems it has createdB.will continue to produce conveniencesC.will stop advancingD.will undo itself(3).The author would say that technological advancement ______.（分数：1.00）A.has done noting to the quality of lifeB.has improved the quality of lifeC.has harmed the quality of lifeD.has redefined the quality of life(4).What do you learn from the phrase "put up or shut up" in the third paragraph?（分数：1.00）A.Technology has put a great deal of stress on people"s lives.B.People can"t live with the stresses caused by technology.C.People are quite active in dealing with the stresses caused by technology.D.People are quite passive in dealing with the stresses caused by technology.(5).It can be concluded from the third paragraph that technological advancement has resulted in quick living pace which ______.（分数：1.00）A.is harmful to societyB.is socially rewardingC.leads to further improvementsD.characterizes modem society十三、Passage Two(总题数：1，分数：5.00)The great question that this paper will, but feebly, attempt to answer is, what is the creative process?Though much theory has accumulated, little is really known about the power that lies at the bottom of poetic creation. It is true that great poets and artists produce beauty by employing all the powers of personality and by fusing emotions, reason, and intuitions. But what is the magical synthesis that joins and arranges these complex parts into poetic unity?John L. Lowes, in his justly famous "The Road to Xanadu", developed one of the earliest and still generally acceptable answers to this tantalizing question. Imaginative creation, he concludes, is a complex process in which the conscious and unconscious minds jointly operate. "There is... the Deep Well with its chaos of fortuitously blending images; but there is likewise the Vision which sees shining in and through the chaos of the potential lines of Form, and with the Vision, the controlling Will, which gives to that potential beauty actuality." The Deep Well is the unconscious mind that is peopled with the facts, ideas, and feelings of the conscious activity. The imaginative vision, an unconscious activity, shines through the land of chaos, of lights and shadows, silently seeking pattern and form. Finally, the conscious mind again, through Will, captures and embodies the idea in the final work of art. In this way is unity born out of chaos. Though there can be no absolute certainty, there is general agreement that the periods in the development of a creative work parallel, to some extent, Lowes" theory of Well, Vision, Form, and Will. There are at least three stages in the creative process: preparation, inspiration, work. In a sense, the period of preparation is all of the writer"s life. It is the Deep Well. It is especially a period of concentration which gives the unconscious mind an opportunity to communicate with the conscious mind. When remembrances of things past reach the conscious level of the writer"s mind, he is ready to go on with the process. Part of this preparation involves learning a medium—learning a language, learning how to write, learning literary forms. It is important to mot here that form cannot be imposed upon the idea. Evidence, though sparse, shows that the idea gives birth to the form that can best convey it. It is the Vision, according to Lowes, which sees shining in and through the chaws of the potential lines of Form..."（分数：5.00）(1).When remembrances of things past reach the conscious level, the post has reached the stage called ______.（分数：1.00）A.WellB.VisionC.FormD.Will(2).Which of the following statements is TRUE?（分数：1.00）A.The form determines the subject matter.B.The idea determines the form.C.Vision makes beauty an actuality.D.A writer is unconscious when he prepares his work.(3).The word "fortuitously" in the third paragraph means ______.（分数：1.00）A.accidentallyB.luckilyC.thoroughlyD.potentially(4).The remembrance of things past is carried on in the ______.（分数：1.00）A.Deep WellB.VisionC.chaotic lights and shadowsD.conscious mind(5).What is the relationship between idea and form?（分数：1.00）A.There is no clear relationship between them.B.Form should be strongly controlled by idea.C.Idea generates form and form reflects idea.D.None of the above.十四、Passage Three(总题数：1，分数：5.00)Some futurologists have assumed that the vast upsurge of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to postpone marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy rebounds, the number of marriages also rises.Coincident with the increase in women working outside the home is the increase in divorce rates. Yet, it may be wrong to jump to any simple cause-and-effect conclusions. The impact of a wife"s work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible. Tensions grounded in financial problems often play a key role in ending a marriage. Given high unemployment, inflationary problems, and slow growth in real earnings, a working wife can increase household income and relieve some of these pressing financial burdens. By raising a family"s standard of living, a working wife may strengthen her family"s financial and emotional stability.Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union.Also, a major part of women"s inequality in marriage has been due to the fact that, in most cases, men have remained the main breadwinners. With higher earning capacity and status occupations outside of the home comes the capacity to exercise power within the family. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities.（分数：5.00）(1).The word "portend" (Line 2, Para. 1) is closest in meaning to "______".（分数：1.00）A.defyB.signalC.suffer fromD.result from(2).It is said in the passage that when the economy slides, ______.（分数：1.00）A.men would choose working women as their marriage partnersB.more women would get married to seek financial securityC.even working women would worry about their marriagesD.more people would prefer to remain single for the time being(3).If women find fulfillment through work outside the home, ______.（分数：1.00）A.they are more likely to dominate their marriage partnersB.their husbands are expected to do more houseworkC.their marriage ties can be strengthenedD.they tend to put their career before marriage(4).One reason why women with no career may seek a divorce is that ______.（分数：1.00）A.they feel that they have been robbed of their freedomB.they are afraid of being bossed around by their husbandsC.they feel that their partners fail to live up to their expectationsD.they tend to suspect their husbands loyalty to their marriage(5).Which of the following statements can best summarize the author"s view in the passage?（分数：1.00）A.The stability of marriage and the divorce rate may reflect the economic situation of the country.B.Even when economically independent, most women have to straggle for real equality in marriage.C.In order to secure their marriage women should work outside the home and remain independent.D.The impact of the growing female workforce on marriage varies from case to case.十五、Passage Four(总题数：1，分数：5.00)Auctions are public sales of goods, conducted by an officially approved auctioneer. He asked the crowd to gather in the auction room to bid for 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 raised platform.The ancient Romans probably invented sales by auction and the English word comes from the Latin "autic", meaning "increase". The Romans usually sold in this way the spoils taken in war, these sales were called "sub hasta", 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 was burning.Practically all goods can be sold by auction. Among these are coffee, skins, wool, tea, cocoa, furs, fruit, vegetables and wines. Auction sales are also usual for land and property, antique furniture, pictures, rare books, old china and works of art. The auction rooms at Chritie"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 the 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 one and continue the numerical order; he may wait until he notices the fact that certain buyers 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 the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding.（分数：5.00）(1).Auctioned goods are sold ______.（分数：1.00）A.for the highest price offeredB.at fixed pricesC.at prices lower than their true valueD.at prices offered by the auctioneer(2).The end of bidding is called "knocking down" because ______.（分数：1.00）A.the auctioneer knocks on the tableB.the auctioneers names the highest bidder as the buyer of the goodsC.the goods are knocked down onto the tableD.the auctioneer bangs the table with a hammer(3).In the sentence "The Romans usually sold in this way the spoils taken in war," the word "spoils" most probably means ______.（分数：1.00）eless goodsB.spearsC.various kinds of foodD.property taken from the enemy(4).In England a candle used to burn at auction sales ______.（分数：1.00）A.because the auction sales took place at nightB.as a signal for the crowd to gatherC.to keep the auction room warmD.to limit the time when offers of prices could be made(5).An auction catalogue gives buyers ______.（分数：1.00）A.the current market values of the goodsB.details of the goods to be soldC.the order in which goods are to be soldD.free admission to the auction sale十六、Passage Five(总题数：1，分数：5.00)Conventional wisdom about conflict seems pretty much cut and dried. Too little conflict breeds apathy (冷漠) and stagnation (呆滞). Too much conflict leads to divisiveness (分裂) and hostility. Moderate levels of conflict, however, can spark creativity and motivate people in a healthy and competitive way.Recent research by Professor Charles R. Schwenk, however, suggests that the optimal level of conflict may be more complex to determine than these simple generalizations. He studied perceptions of conflict among a sample of executives. Some of the executives worked forprofit-seeking organizations and others for not-for-profit organizations.Somewhat surprisingly, Schwenk found that opinions about conflict varied systematically as a function of the type of organization. Specifically, managers in not-for-profit organizations strongly believed that conflict was beneficial to their organizations and that it promoted higher quality decision making than might be achieved in the absence of conflict.Managers of for-profit organizations saw a different picture. They believed that conflict generally was damaging and usually led to poor-quality decision making in their organizations. Schwenk interpreted these results in terms of the criteria for effective decision making suggested by the executives. In the profit-seeking organizations, decision-making effectiveness was most often assessed in financial terms. The executives believed that consensus rather than conflict enhanced financial indicators.In the not-for-profit organizations, decision-making effectiveness was defined from the perspective of satisfying constituents. Given the complexities and ambiguities associated with satisfying many diverse constituents executives perceived that conflict led to more considered and acceptable decisions.（分数：5.00）(1).In the eyes of the author, conventional opinion on conflict is ______.（分数：1.00）A.wrongB.oversimplifiedC.misleadingD.unclear(2).Professor Charles R. Schwenk"s research shows ______.（分数：1.00）A.the advantages and disadvantages of conflictB.the real value of conflictC.the difficulty in determining the optimal level of conflictD.the complexity of defining the roles of conflict(3).We can learn from Schwenk"s research that ______.（分数：1.00）A.a personls view of conflict is influenced by the purpose of his organizationB.conflict is necessary for managers of for-profit organizationsC.different people resolve conflicts in different waysD.it is impossible for people to avoid conflict(4).The passage suggests that in for-profit organizations ______.（分数：1.00）A.there is no end of conflictB.expression of different opinions is encouragedC.decisions must be justifiableD.success lies in general agreement(5).People working in a not-for-profit organization ______.（分数：1.00）A.seem to be difficult to satisfyB.are free to express diverse opinionsC.are less effective in making decisionsD.find it easier to reach agreement十七、Passage Six(总题数：1，分数：5.00)In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn"t any crime to worry about. Amazingly, these happy times appear still to be with us in the world"s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up homes without fitting locks to their doors.SATAN can try out a variety of well-known hacking tricks on an Internet site without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle.But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage. But let"s look on the bright side. Given the lack of locks, the Internet is surely the world"s biggest (almost) crime-flee society. Maybe that is because hackers are fundamentally honest. Or that there currently isn"t much to steal. Or because vandalism isn"t much fun unless you have a peculiar dislike for someone.。

医学考博公共英语模拟题三Part IV.Reading Comprehension(30%)Directions:In this part of the test there are six passages. Following each passage there are five questions with four choices. Choose the best answer and mark your answer on the ANSWER SHEET.Passage OneCells cannot remain alive outside certain limits of temperature, and much narrower limits mark the boundaries of effective functioning. Enzyme(酶)systems of mammals and birds are most efficient only within a narrow range around37ºC;a departure of a few degrees from this value seriously impairs their functioning.Even though cells can survive wider fluctuations,the integrated actions of bodily systems are impaired.Other animals have a wider tolerance for changes of bodily temperature.For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperatures.Ways of characterizing the difference have become more accurate and meaningful over time,but popular terminology still reflects the old division into“warm-blooded’and“cold-blooded”species; warm-blooded included mammals and birds,whereas all other creatures were considered cold-blooded.As more species were studied,it became evident that this classification was inadequate.A fence lizard or a desert iguana(鬣蜥)—each cold-blooded—usually has a body temperature only a degree or two below that of humans and so is notcold.Therefore the next distinction was made between animals that maintain a constant body temperature,called homotherms(同温动物), and those whose body temperature varies with their environment, called poikilotherms(变温动物).But this classification also proved inadequate,because among mammals there are many that vary their body temperatures during hibernation.Furthermore,many invertebrates(无脊椎动物)that live in the depths of the ocean never experience a change in the chill of the deep water,and their body temperatures remain constant.The current distinction is between animals whose body temperature is regulated chiefly by internal metabolic processes and those whose temperature is regulated by,and who get most of their heat from,the environment.The former are called endotherms(恒温动物),and the latter are called ectotherms(外温动物).Most ectotherms do regulate their body temperature,and they do so mainly by locomoting to favorable sites or by changing their exposure to external sources of heat.Endotherms(mainly mammals and birds)also regulate their temperature by choosing favorable environments,but primarily they regulate their temperatures by making a variety of internal adjustments.（PS:The way to contact yumingkaobo TEL:si ling ling-liu liu ba-l iu jiu qi ba QQ:si jiu san san qi yi liu er liu）61.The passage mainly discusses_______.A.body temperatures of various animalsB.the newest research on measuring temperatureC.methods of temperature reductionD.the classification of animals by temperature regulation62.Which of the following terms refers primarily to mammals and birds?A.Warm-blooded.B.Ectothermic.C.Cold-blooded.D.Poikilothermic63.In general,the temperature of endotherms is regulated _______.A.consciouslyB.internallyC.inadequatelyD.environmentally64.According to the passage,the chief way in which ectotherms regulate their temperature is by_______.A.seeking out appropriate locationsB.hibernating part of the yearC.staying in deep waterD.triggering certain metabolic processes65.According to the passage,human beings mainly regulate their body temperatures by_______.A.choosing favorable environmentsB.internal metabolic processesC.eating more foodD.doing physical exercisesPassage TwoThe narrow passage ended in a round arch fringed with ivy and creepers.The children passed through the arch into a narrow ravine whose banks were of stone,moss-covered.Trees growing on the top of the bank arched across and the sunlight came through in changing patches of brightness.The path,which was of greeny-grey stones where heaps of leaves had drifted,sloped steeply down,and at the end of it was another round arch,quite dark inside,above which were rose rocks and grass and bushes.“It’s like the outside of a railway tunnel,”said Jimmy.“It might be the entrance to an enchanted castle,”said Kathleen.Under the drifted damp leaves the path was firm and stony.At the dark arch they stopped.“There are steps down,”said Gerald.Very slowly and carefully they went down the steps.Gerald struck a match when the last step was found to have no edge and to be in fact the beginning of a passage turning to the left.“This,”said Jimmy,“might take us back to the road.”“Or under it,”said Gerald,“we’ve come down eleven steps.”They went on,following Gerald,who went very slowly for fear, as he explained,of steps.The passage was very dark.Then came a glimmer of daylight that grew and grew and presently ended in another arch that looked out over a scene so like a picture out of a book about Italy that everyone’s breath was taken away,andthey simply walked forward silent and staring.A short avenue of cypresses led,winding as it went,to a marble terrace that lay broad and white in the sunlight.The children,blinking,leaned their arms on the flat balustrade(栏杆)and gazed.本文由“育明考博”整理编辑。

Choose the best answer and mark the letter ofyour choice on the ANSWER SHEET .For years, scientists have been warning us that the radiation from mobile phones is detrimental to our health, without actually having any evidence to back these __51__up. However, research now suggests that mobile phone radiation has at least onepositive side effect: it can help prevent Alzheimer ’s, __52__ in the mice that acted as test subjects.It’s been suspected, though never proven, that heavy use of mobile phones is badfor your health.It ’s thought that walking around with a cellphone permanently attached to the side of your head is almost sure to be __53__ your brain. And that may well be true, but I ’d rather wait until it ’s proven before giving up that part of my daily life.But what has now been proven, in a very perfunctory manner, is that mobile phone radiation can have an effect on your brain. __54__ in this case it was a positiverather than negative effect.According to BBC news, the Florida Alzheimer ’s Disease Research Center conducteda study on 96 mice to see if the radiation given off by mobile phones could affect theonset of Alzheimer ’s.Some of the mice were “genetically altered to develop beta-amyloid plaques in their brains” __55__ they aged. These are a marker of Alzheimer ’s. all 96 mice were then “exposed to the electro-magnetic __56__ generated by a standard phone for twoone-hour periods each day for seven to nine months. ” The lucky things.__57__ the experiment showed that the mice altered to be predisposed to dementia were protected from the disease if exposed before the onset of the illness. Theircognitive abilities were so unimpaired as to be virtually __58__ to the mice notgenetically altered in any way.Unfortunately, although the results are positive, the scientists don ’t actually know why exposure to mobile phone radiation has this effect. But it ’s hoped thatfurther study and testing could result in a non-invasive __59__ for preventing andtreating Alzheimer ’s disease.Autopsies carried out on the mice also concluded no ill-effects of their exposure to the radiation.However, the fact that the radiation prevented Alzheimer ’s means mobile phones __60__ our brainsand bodies in ways not yet explored.

For each question there are four possible answersmarked A, B, C, and D. Choose the best answer and mark theletter of your choice on the ANSWER SHEET .Passage oneI have just returned from Mexico, where I visited a factory making medicalmasks. Faced with fierce competition, the owner has cut his costs by outsourcing some of his production. Scores of people work for him in their homes, threading elastic into masks by hand. They are paid below the minimum wage, with no job security and no healthcare provision.Users of medical masks and other laboratory gear probably give little thought to where their equipment comes from. That needs to change. A significant proportion of these products are made in the developing world by low-paid people with inadequate labor rights. This leads to human misery ona tremendous scale.Take lab coats. Many are made in India, where most cotton farmers are paid an unfair price for their crops and factory employees work illegal hours for poor pay.One-fifth of the world ’s surgical instruments are made in northern Pakistan. When I visited the area a couple of years ago I found most workers toiling 12 hours a day, seven days a week, for less than a dollar a day, exposed to noise, metal dust and toxic chemicals. Thousands of children, some as young as 7, work in the industry.To win international contracts, factory owners must offer rock-bottomprices, and consequently drive down wages and labor conditions as far as they can. We laboratory scientists in the developed world may unwittingly be encouraging this: we ask how much our equipment will cost, but which of us asks who made it and how much they were paid?This is no small matter. Science is supposed to benefit humanity, but because of the9 / 18word.conditions under which their tools are made, may scientists may actually be causing harm.What can be done? A knee-jerk boycott of unethical goods is not the answer; it would just make things worse for workers in those manufacturing zones. What we need is to start asking suppliers to be transparent about where and how their products are manufactured and urge them to improvetheir manufacturing practices.It can be done. Many universities are committed to fair trade in the form of ethically sourced tea, coffee or bananas. That model should beextended to laboratory goods.There are signs that things are moving. Over the past few years I have worked with health services in the UK and in Sweden. Both have recentlyinstituted ethical procurement practices. If science is truly going to help humanity, it needs to follow suit.61.From the medical masks to lab coats, the author is trying to tell us .A.the practice of occupational protection in the developing worldB.the developing countries plagued by poverty and disease.C.the cheapest labor in the developing countries.D.the human misery behind them.62.The concerning phenomenon the author has observed, according to the passage,A.is nothing but the repetition of the miserable history.B.could have been even exaggerated.C.is unfamiliar to the wealthy west.D.is prevailing across the world.63.The author argues that when researchers in the wealthy west buy thetools of their trade, they should .A.have the same concern with the developing countries.B.be blind to their sources for the sake of humanityC.pursue good bargains in the international market.D.spare a thought for how they were made.64. A proper course of action suggested by the author is .A.to refuse to import the unethical goods from the developing world.B.to ask scientists to tell the truth as the prime value of their work.C.to urge the manufacturers to address the immoral issues.D.to improve the transparency of international contracts.65.By saying at the end of the passage that if science is truly going tohelp humanity, it needs to follow suit, the author means that .A.the scientific community should stand up for all humanityB.the prime value of scientists’ work is to tell the truth.boratory goods also need to be ethically sourced.D.because of science, there is hope for humanity.Passage twoA little information is a dangerous thing. A lot of information, if it’s inaccurate orconfusing, even more so. This is a problem for anyone trying to spend orinvest in an environmentally sustainable way. Investors are barraged withindexes purporting to describe companie’s eco-credentials, some of dubious quality. Green labels on consumer products are ubiquitous, but their claims arehard to verify.The confusion is evident form New Scientist’ s analysis of whether public perceptions of companies’ green credentials reflect reality. It shows that many companies considered“ green” have done little to earn that reputation, while others do not get sufficient credit for their efforts to reduce their environmental impact. Obtaining better information is crucial, because decisions by consumers and big investors will help propel us towards a green economy.At present, it is too easy to make unverified claims. Take disclosure ofgreenhouse gas emissions, for example. There are voluntary schemes such as the Carbon Disclosure Project, but little scrutiny of the figures companies submit, which means investors may be misled.Measurements can be difficult to interpret, too, like those for water sue.In this case, context is crucial: a little from rain-soaked Ireland is notthe same as a little drawn from the Arizona desert.Similar problems bedevil “green” labels attached to individual products.Here, the computer equipment rating system developed by the Green ElectronicsCouncil shows the way forward. Its criteria come from the IEEE, the world ’s leading professional association for technology/Other schemes, such as the “sustainability index” planned by US retail giant Walmart, are broader. Developing rigorous standards for a large number of different types of product will be tough, placing a huge burden on the academic-led consortium that is doing the underlying scientific work.Our investigation also reveals that many companies choose not to disclosedata. Some will want to keep it that way. This is why we need legalrequirements for full disclosure of environmental information, with the clearmessage that the polluter will eventually be required to pay. Then marketforces will drive companies to clean up their acts.Let ’s hope we can rise to this challenge. Before we can have a green economy we need a green information economy –and it ’s the quality of information, as well as its quantity, that will count.66.T“he confusion ” at the beginning of the 2 nd paragraph refers to .A.where to spend or invest in a sustainable wayB.an array of consumer products to chooseC.a fog of unreliable green informationD.little information on eco-credibility67.From the New Scientist’ s analysis it can be inferred that in many casesA.eco-credibility is abusedB.a green economy is crucialC.an environmental impact is lessenedD.green credentials promote green economy68.From unverified claims to difficult measurements and then toindividual products, the author argues that .A.eco-credibility is a game between scientists and manufacturesB.neither scientists nor manufactures are honestC.it is vital to build a green economyD.better information is critical69.To address the issue, the author is crying for .A.transparent corporate managementB.establishing sustainability indexesC.tough academic-led surveillanceD.strict legal weapons70.Which of the following can be the best inference from the last paragraph?A.The toughest challenge is the best opportunity.B.It is time for another green revolution.rmation should be free for all.D.No quantity, no quality.Passage ThreePeople are extraordinarily skilled at spotting cheats –much better than they are detecting rule-breaking that does not involve cheating. A study showing just how good we are at this adds weight to the theory that our exceptional brainpower arose through evolutionary pressures to acquire specific cognitive skills.The still-controversial idea that humans have specialized decision-making systems in addition to generalized reasoning has been around for decades. Its advocates point out that the ability to identify untrustworthy people should be favored evolutionarily, since cheats risk undermining the social interactions in which people trade goods or services for mutual benefit.The test whether we have a special ability to reason about cheating, Leda Cosmides, an evolutionary psychologist at the University of California, Santa Barbara, and her colleagues used a standard psychological test called the Wason selection task, which tests volunteers’ ability to reason about “if/then” statements.The researchers set up scenarios in which they asked undergraduate volunteers to imagine they were supervising workers sorting appliances for admission to two schools; a good one in a district where school taxes are high, and a poor one in an equally wealthy, but lightly taxed district. The hypothetical workers were supposed to follow a rule that specified “if a student is admitted to the good school ”, they must live in the highly taxed district.Half the time, the test subjects were told that the workers had children of their own applying to the schools, thus having a motive to cheat; the rest of the time they were told the workers were merely absent-minded and sometimes made innocent errors. Then the test subjects were asked how they would verify that the workers were not breaking the rule.Cosmides found that when the “supervisors” thought they were checking for innocent errors, just 9 of 33, or 27 percent, got the right answer –looking for a student admitted to the good school who did not live in thehighly taxed district. In contrast, when the supervisors thought they were watching for cheats, they did much better, with 23 of 34, or 68 percent, getting the right answer.This suggests that people are, indeed, more adept at spotting cheat than at detecting mere rule-breaking, Cosmides said.“Any cues that it’s just an innocent mistake actually inactivate the detection mechanism”.Other psychologists remain skeptical of this conclusion. “If you want to conclude that therefore there’ s a module in the mind for detecting cheaters, I see zero evidence for that, ” says Steven Sloman, a cognitive scientists at Brown University in Province, Rhode Island. “It’s certainly possible that it’s something we learned through experience.There’ s no evident that it’s anything innate.”71.The findings of the study were in favor of _.A.the highly developed skills of cheating at schoolB.the relation between intelligence and evolutionC.the phenomenon of cheating at schoolD.the human innate ability to cheat72.The test “supervisors” appeared to be more adept at .A.spotting cheats than detecting mere rule-breakingB.detecting mere rule-breaking than spotting cheatsC.spotting their own children cheating than others doing itD.detecting cheats in the highly taxed district than in the lightlytaxed one73.When she says that ⋯that can’ t be the only thing going on in the mind , Cosmides most probably implies that .A.cheating is highly motivated in the social interactionsB.our specific cognitive skills can serve an evolutionary purposeC.there is no such a mental thing as a specialized decision-makingsystemD.the ability to identify untrustworthy people should be favoredevolutionary74.In response to Cosmides’ claim, Sloman would say that .A.it was of great possibilityB.it could be misleadingC.it was unbelievableD.it ’s acquired75.Which of the following can be the best title for the passage?A.Cheating at SchoolB.Cheating as the Human NatureC.Imaginary Intelligence and CheatingD.Intelligence Evolved to Root Out CheatsPassage FourFor many environmentalists, all human influence on the planet is bad. Many natural scientists implicitly share this outlook. This is not unscientific, but it can create the impression that greens andenvironmental scientists are authoritarian tree-huggers who value nature above people. That doesn’ t play well with mainstream society, as the apparent backlash against climate science reveals.Environmentalists need to find a new story to tell. Like it or not, we now live in the anthropocene （人类世）–an age in which humans are perturbing many of the planet ’snatural systems, from the water cycle to the acidity of the oceans. Wecannot wish that away; we must recognize it and manage our impacts.Johan Rockstrom, head of the Stockholm Environment Institute in Sweden,and colleagues have distilled recent research on how Earth systems work intoa list of nine “planetary boundaries” that we must stay within to live sustainably. It is preliminary work, and many will disagree with where theboundaries are set. But the point is to offer a new way of thinking about ourrelationship with the environment – a science-based picture that accepts a certain level of human impact and even allows us some room to expand. The result is a breath of fresh air: though we are already well past three of the boundaries, we haven’ t trashed the place yet.It is in the same spirit that we also probe the basis for key claims inthe Intergovernmental Panel on Climate Change’ s 2007 report on climate impacts. This report has been much discussed since our revelations about its unsubstantiated statement on melting Himalayan glaciers. Why return to the topic? Because there is a sense that the IPCC shares the same anti-human agenda and, as a result, is too credulous of unverified numbers. While the majority of the report is assuredly rigorous, there is no escaping the fact that parts of it make claims that go beyond the science.For example, the chapter on Africa exaggerates a claim about crashes in farm yields, and also highlights projections of increased water stress in some regions while ignoring projections in the same study that point to reduced water stress in other regions. There errors are not trifling. They are among the repor’ ts headline conclusions.Above all, we need a dispassionate view of the state of the planet and our likely future impact on it. There ’s no room for complacency: Rockstrom ’s analysis shows us that we face real dangers, but exaggerating our problems is not the way to solve them.76.As the first paragraph implies, there is between environmentalists and mainstream society __________ .A.a misunderstandingB.a confrontationC.a collaborationD.a consensus77.Within the planetary boundaries, as Rockstrom implies, .A.we humans have gone far beyond the limitationsB.our human activities are actually moderate in degreeC.a certain level of human impact is naturally acceptableD.it is urgent to modify our relationship with the environment78.The point, based on Rockstrom ’s investigation, is simply that .A.they made the first classification of Earth systems。
