重庆医科大学2013年博士研究生入学考试（英语）真题重庆医科大学2013年博士研究生入学考试（英语）真题Despite Denmark's manifest virtues, Danes never talk abouthow proud they are to be Danes. This would sound weird in Danish. When Danestalk to foreigners about Denmark, they always begin by commenting on itstininess, its unimportance, the difficulty of its language, the generalsmall-mindedness and self-indulgence of their countrymen and the high taxes. NoDane would look you in the eye and say, “Denmark is a great country.” You'resupposed to figure this out for yourself.It is the land of the silk safety net, where almost half thenational budget goes toward smoothing out life's inequalities, and there isplenty of money for schools, day care, retraining programmes, jobseminars—Danes love seminars: three days at a study centre hearing about wastemanagement is almost as good as a ski trip. It is a culture bombarded byEnglish, in advertising, pop music, the Internet, and despite all the Englishthat Danish absorbs—there is no Danish Academy to defend against it—olddialects persist in Jutland that can barely be understood by Copenhageners. Itis the land where, as the saying goes, “ Few have too much and fewer have toolittle,” and a foreigner is struck by the sweet egalitarianism that prevails,where the lowliest clerk gives you a level gaze, where Sir and Madame havedisappeared from common usage, even Mr. and Mrs. It's a nation of recyclers—about55% of Danish garbage gets made into something new—and no nuclear power plants.It's a nation of tireless planners. Trains run on time. Things operate well ingeneral.Such a nation of overachievers—a brochure from theMinistryof Business and Industry says, “Denmark is one of the world's cleanest and mostorganized countries, with virtually no pollution, crime, or poverty. Denmark isthe most corruption-f ree society in the Northern Hemisphere.” So, of course,one's heart lifts at any sighting of Danish sleaze: skinhead graffiti onbuildings (“Foreigners Out of Denmark!”), broken beer bottles in the gutters,drunken teenagers slumped in the park. Nonetheless, it is an orderly land. You drive through aDanish town, it comes to an end at a stone wall, and on the other side is afield of barley, a nice clean line: town here, country there. It is not anation of jaywalkers. People stand on the curb and wait for the red light tochange, even if it's 2 a.m. and there's not a car in sight. However, Danes don'tthink of themselves as a waiting-at-2-a.m.-for-the-green-light people—that'show they see Swedes and Germans. Danes see themselves as jazzy people,improvisers, more free spirited than Swedes, but the truth is (though oneshould not say it) that Danes are very much like Germans and Swedes.Orderliness is a main selling point. Denmark has few natural resources, limitedmanufacturing capability; its future in Europe will be as a broker, banker, anddistributor of goods. You send your goods by container ship to Copenhagen, andthese bright, young,English-speaking, utterly honest, highly disciplinedpeople will get your goods around to Scandinavia, the Baltic States, andRussia. Airports, seaports, highways, and rail lines are ultramodern andwell-maintained.The orderliness of the society doesn't mean that Danishlives are less messy or lonely than yours or mine, and no Dane would tell youso. You can hear plenty about bitter family feuds and the sorrows of alcoholismand about perfectly sensible people whowent off one day and killed themselves.An orderly society can not exempt its members from the hazards of life.But there is a sense of entitlement and security that Danesgrow up with. Certain things are yours by virtue of citizenship, and youshouldn't feel bad for taking what you're entitled to, you're as good as anyoneelse. The rules of the welfare system are clear to everyone, the benefits youget if you lose your job, the steps you take to get a new one; and theorderliness of the system makes it possible for the country to weather highunemployment and social unrest without a sense of crisis.16. The author thinks that Danes adopt a ________ attitudetowards their country.A. boastfu lB.modestC. deprecatingD. mysterious17. Which of the following is NOT a Danish characteristiccited in the passage?A. Fondness of foreign culture.B. Equality in society.C. Linguistic tolerance.D. Persistent planning.18. The author's reaction to the statement by the Ministryof Business and Industry is ________.A. disapprovingB. approvingC. noncommittalD. doubtful19. According to the passage, Danish orderliness ________.A. sets the people apart from Germans and SwedesB. spares Danes social troubles besetting other peoplesC. is considered economically essential to the countryD. prevents Danes from acknowledging existing troubles20. At the end of the passage the author states all thefollowing EXCEPT that ________.A. Danes are clearly informed of their social benefitsB. Danes take for granted what is given to themC. the open system helps to tide the country overD. orderliness has alleviated unemploymentCooperative competition. Competitivecooperation. Confused? Airline alliances have travellers scratching their headsover what's going on in the skies. Some folks view alliances as a blessing totravellers, offering seamless travel, reduced fares and enhanced frequent-flyerbenefits. Others see a。

Playing “action” video games improves a visual ability __51__ tasks like reading and driving at night, a new study says. The ability, called contrast sensitivity function, allows people to discern even subtle changes __52__ gray against a uniformly colored backdrop. It’s also one of the first visual aptitudes to fade with age. __53__ a regular regimen of action video game training can provide long-lasting visual power, according to work led by Daphne Bavelier of the University of Rochester.Previous research shows that gaming improves other visual skills, such as the ability to track several objects at the same time and __54__ attention to a series of fast-moving events. Bavelier said, “A lot of different aspects of the visual system are being enhanced, __55__.”The new work suggests that playing video games could someday become part of vision-correction treatments, which currently rely mainly on surgery or corrective lenses. “__56__ you’ve had eye surgery or get corrective lenses, exposing yourself to these games should help the optical system to recover faster and better, you need to retrain the brain to make use of the better, crisper information that’s coming in __57__ your improved eyesight,” Bavelier said.Expert action gamers in the study played first-person shooters Unreal Tournament 2004 and Call of Duty 2. A group of experienced nonaction gamers played The Sims 2, a “life simulation” video game. The players of nonaction video games didn’t see the same vision __58__, the study says. Bavelier and others are now trying to figure out exactly why action games __59__ seem to sharpen visual skill. It may be that locating enemies and aiming accurately is a strenuous, strength-building workout for the eyes, she said. Another possible __60__ is that the unpredictable, fast-changing environment of the typical action game requires players to constantly monitor entire landscapes and analyze optical data quickly.51.

A. benefitsB. defectsC. approachesD. risks59. A. in caseB. in advanceC. in returnD. in particular60. A. effectB. reasonC. outcomeD. conclusionPart IV Reading Comprehension (30%)Directions:In this part there are six passages, each of which is followed by five questions. For each question there are four possible answers marked A, B,C, and D. Choose the best answer and mark the letter of your choice onthe ANSWER SHEET.Passage oneThere is plenty we don’t know about criminal behavior. Most crime goes unreported so it is hard to pick out trends from the data, and even reliable sets of statistics can be difficult to compare. But here is one thing we do know: those with a biological predisposition to violent behavior who are brought up in abusive homes are very likely to become lifelong criminals.Antisocial and criminal behavior tends to run in families, but no one was sure whether this was due mostly to social-environmental factors or biological ones. It turns out both are important, but the effect is most dramatic when they act together. This has been illustrated in several studies over the past six years which found that male victims of child abuse are several times as likely to become criminals and abusers themselves if they were born with a less-active version of a gene for the enzyme monoamine oxidase A (MAO-A), which breaks down neurotransmitters crucial to the regulation of aggression.Researchers recently made another key observation: kids with this “double whammy” of predisposition and an unfortunate upbringing are likely to show signs of what’s to come at a very early age. The risk factors for long-term criminality – attention deficit hyperactivity disorder, low IQ, language difficulties – can be spotted in kindergarten. So given what we now know, shouldn’t we be doing everything to protect the children most at risk?No one is suggesting testing all boys to see which variant of the MAO-A gene they have, but what the science is telling us is that we should redouble efforts to tackle abusive upbringings, and even simple neglect. This will help any child, but especially those whose biology makes them vulnerable. Thankfully there is already considerable enthusiasm in both the US and the UK for converting the latest in behavioral science into parenting and social skills: both governments have schemes in place to improve parenting in families where children are at risk of receiving poor care.Some people are uncomfortable with the idea of early intervention because it implies our behavior becomes “set” as we grow up, compromising the idea of free will. That view is understandable, but it would be negligent to ignore what the studies are telling us. Indeed, the cost to society of failing to intervene －in terms of criminal damage, dealing with offenders and helping victims of crime －is bound to be greater than the cost of improving parenting. The value to the children is immeasurable.61. Researchers have come to a consensus: to explain violent behavior ________.A. in terms of physical environmentB. form a biological perspectiveC. based on the empirical dataD. in a statistical way62. When we say that antisocial and criminal behavior tends to run in families, asindicated by the recent findings, we can probably mean that ___________.A. a particular gene is passed on in familiesB. child abuse will lead to domestic violenceC. the male victims of child abuse will pass on the tendencyD. the violent predisposition is exclusively born of child abuse63. The recent observation implicated that to check the development of antisocialand criminal behavior ___________.A. boys are to be screened for the biological predispositionB. high-risk kids should be brought up in kindergartenC. it is important to spot the genes for the risk factorsD. active measures ought to be taken at an early age64. To defend the argument against the unfavorable idea, the author makes it apoint to consider ___________.A. the immeasurable value of the genetic research on behaviorB. the consequences of compromising democracyC. the huge cost of improving parenting skillsD. the greater cost of failing to intervene65. Which of the following can be the best title for the passage?A. Parenting Strategies for KidsB. The Making of a CriminalC. Parental EducationD. Abusive ParentingPassage twoAfter 25 years battling the mother of all viruses, have we finally got the measure of HIV? Three developments featured in this issue collectively give grounds for optimism that would have been scarcely believable a year ago in the wake of another failed vaccine and continuing problems supplying drugs to all who need them.Perhaps the most compelling hope lies in the apparent “cure” of a man with HIV who had also developed leukemia. Doctors treated his leukemia with a bone marrow transplant that also vanquished the virus. Now US Company Sangamo Biosciences is hoping to emulate the effect patients being cured with a single shot of gene therapy, instead of taking antiretroviral drugs for life.Antiretroviral therapy (ART) is itself another reason for optimism. Researchers at the World Health Organization have calculated that HIV could be effectively eradicated in Africa and other hard-hit places using existing drugs. The trick is to test everyone often, and give those who test positive ART as soon as possible. Because the drugs rapidly reduce circulating levels of the virus to almost zero, it would stop people passing it on through sex. By blocking the cycle of infection in this way, the virus could be virtually eradicated by 2050.Bankrolling such a long-term program would cost serious money – initially around $3.5 billion a year in South Africa alone, ring to $85 billion in total. Huge as it sounds, however, it is peanuts compared with the estimated $1.9 trillion cost of the Iraq war, or the $700 billion spent in one go propping up the US banking sector. It also look small beer compared with the costs of carrying on as usual, which the WHO says can only lead to spiraling cases and costs.The final bit of good news is that the cost of ART could keep on falling. Last Friday, GlaxoSmithKline chairman Andrew Witty said that his company would offer all its medicines to the poorest countries for at least 25 per cent less than the typical price in rich countries. GSK has already been doing this for ART, but the hope is that the company may now offer it cheaper still and that other firms will follow their lead.No one doubt the devastation caused by AIDS. In 2007, 2 million people died and 2.7 million more contracted the virus. Those dismal numbers are not going to turn around soon – and they won’t turn around at all without huge effort and investment. But at least there is renewed belief that, given the time and money, we can finally start riddling the world of this most fearsome of viruses.66. Which is the following can be most probably perceived beyond the first paragraph?A. The end of the world.B. A candle of hope.C. A Nobel prize.D. A Quick Fix.67. According to the passage, the apparent “cure” of the HIV patient who had alsodeveloped leukemia would ___________.A. make a promising transition from antiretroviral medication to gene therapyB. facilitate the development of effective vaccines for the infectionC. compel people to draw an analogy between AIDS and leukemiaD. would change the way we look at those with AIDS68. As another bit of good news, ___________.A. HIV will be virtually wiped out first in AfricaB. the cycle of HIV infection can be broken with ARTC. the circulating levels of HIV have been limited to almost zeroD. the existing HIV drugs will be enhanced to be more effective in 25 years69. The last reason for optimism is that ___________.A. governments will invest more in improving ARTB. the cost of antiretroviral therapy is on the declineC. everybody can afford antiretroviral therapy in the worldD. the financial support of ART is coming to be no problem70. The whole passage carries a tone of ___________.A. idealismB. activismC. criticismD. optimismPassage ThreeArchaeology can tell us plenty about how humans looked and the way they lived tens of thousands of years ago. But what about the deeper questions? Could early humans speak, were they capable of self-conscious reflection, did they believe in anything?Such questions might seem to be beyond the scope of science. Not so. Answering them is the focus of a burgeoning field that brings together archaeology and neuroscience. It aims to chart the development of human cognitive powers. This is not easy to do. A skull gives no indication of whether its owner was capable of speech, for example. The task then is to find proxies (替代物)for key traits and behaviors that have stayed intact over millennia.Perhaps the most intriguing aspect of this endeavor is teasing out the role of culture as a force in the evolution of our mental skills. For decades, development of the brain has been seen as exclusively biological. But increasingly, that is being challenged.Take what the Cambridge archaeologist Colin Renfrew calls “the sapient (智人的) paradox (矛盾)”. Evidence suggests that the human genome, and hence the brain, has changed little in the past 60,000 years. Yet it wasn’t until about 10,000 years ago that profound changes took place in human behavior: people settled in villages and built shrines. Renfrew’s paradox is why, if the hardware was in place, did it take so long for humans to start changing the world?His answer is that the software – the culture – took a long time to develop. In particular, the intervening time saw humans vest (赋予) meaning in objects and symbols. Those meanings were developed by social interaction over successive generations,passed on through teaching, and stored in the neuronal connections of children.Culture also changes biology by modifying natural selection, sometimes in surprising ways. How is it, for example, that a human gene for making essential vitamin C became blocked by junk DNA? One answer is that our ancestors started eating fruit, so the pressure to make vitamin C “relaxed” and the gene became unnecessary. By this reasoning, early humans then became addicted to fruit, and any gene that helped them to find it was selected for.Evidence suggests that the brain is so plastic that, like genes, it can be changed by relaxing selection pressure. Our understanding of human cognitive development is still fragmented and confused, however. We have lots of proposed causes and effects, and hypotheses to explain them. Yet the potential pay-off makes answers worth searching for. If we know where the human mind came from and what changed it, perhaps we can gauge where it is going. Finding those answers will take all the ingenuity the modern human mind can muster.71. The questions presented in the first paragraph ___________.A. seem to have no answers whateverB. are intended to dig for ancient human mindsC. are not scientific enough to be answered hereD. are raised to explore the evolution of human appearance72. The scientists find the proxy to be ___________.A. the role of cultureB. the passage of timeC. the structure of a skullD. the biological makeup of the brain73. According to Renfrew’s paradox, the transition from 60,000 to 10,000 years agosuggests that ___________.A. human civilization came too lateB. the hardware retained biologically staticC. it took so long for the software to evolveD. there existed an interaction between gene and environment74. From the example illustrating the relation between culture and biology, wemight conclude that ___________.A. the mental development has not been exclusively biologicalB. the brain and culture have not developed at the same paceC. the theory of natural selection applies to human evolutionD. vitamin C contributes to the development of the brain75. Speaking of the human mind, the author would say that ___________.A. its cognitive development is extremely slowB. to know its past is to understand its futureC. its biological evolution is hard to predictD. as the brain develops, so as the mindPassage FourDespite the numerous warnings about extreme weather, rising sea levels and mass extinctions, one message seems to have got lost in the debate about the impact of climate change. A warmer world won’t just be inconvenient. Huge swathes (片) of it, including most of Europe, the US and Australia as well as all of Africa and China will actually be uninhabitable--- too hot, dry or stormy to sustain a human population.This is no mirage. It could materialize if the world warms by an average of just 4°C, which some models predict could happen as soon as 2050. This is the world our children and grandchildren are going to have to live in. So what are we going to do about it?One option is to start planning to move the at-risk human population to parts of the world where it will still be cool and wet. It might seem like a drastic move, but this thought experiment is not about scaremongering (危言耸听). Every scenario is extrapolated from predictions of the latest climate models, and some say that 4°C may actually turn out to be a conservative estimate.Clearly this glacier-free, desertified world---with its human population packed into high-rise cities closer to the poles---would be a last resort. Aside from anything else, it is far from being the most practical option: any attempt at mass migration is likely to fuel wars, political power struggles and infighting.So what are the alternatives? The most obvious answer is to radically reduce carbon dioxide levels now, by fast-tracking green technologies and urgently implementing energy-efficient measures. But the changes aren’t coming nearly quickly enough and global emissions are still rising. As a result, many scientists are now turning to “Earth’s plan B”.Plan B involves making sure we have large scale geoengineering technologies ready and waiting to either suck CO2 out of the atmosphere or deflect the sun’s heat. Most climate scientists were once firmly against fiddling with the Earth’s thermostat, fearing that it may make a bad situation even worse, or provide politicians with an excuse to sit on their hands and do nothing.Now they reluctantly acknowledge the sad truth that we haven’t managed to reorder the world fast enough to reduce CO2 emissions and that perhaps, given enough funding research and political muscle, we can indeed design, test and regulate geoengineering projects in time to avert the more horrifying consequences of climate change.Whatever we do, now is the time to act. The alternative is to plan for a hothouse world that none of us would recognize as home.76. To begin with, the author is trying to remind us of ____________.A. the likelihood of climate change making life inconvenientB. the warning against worsening climate changeC. the inevitable consequence of global warmingD. the misconception of a warmer world77. As the thought experiment shows, those at risk from global warming will ____________.A. live with the temperature raised by an average of 4°CB. have nowhere to go but live in the desertC. become victims as soon as 2050D. move closer to the poles78. It is clear from the passage that a practical approach to global warming is _________.A. to reduce massively CO2 emissionsB. to take protective measures by 2025C. to prepare a blueprint for mass migrationsD. to launch habitual constructions closer to the poles。
