For each of them there are four choices marked A, B, C and D. Choose the bestone and mark your answer on the ANSER SHEET.Passage OneIn 1900 the United States had only three cities with more than a million residents-New York,Chicago, and Philadelphia. By 1930, it had ten giant metropolises. The newer ones experiencedremarkable growth, which reflected basic changes in the economy.Line The population of Los Angeles (114,000 in 1900) rose spectacularly in the early decades ofthe twentieth century, increasing a dramatic 1,400 percent from 1900 to 1930. A number ofcircumstances contributed to the meteoric rise of Los Angeles. The agricultural potential of the areawas enormous if water for irrigation could be found, and the city founders had the vision and datingto obtain it by constructing a 225-mile aqueduct, completed in 1913, to tap the water of the OwensRiver. The city had a superb natural harbor, as well as excellent rail connections. The climate made itpossible to shoot motion pictures year-round; hence Hollywood. Hollywood not only supplied jobs; itdisseminated an image of the good life in Southern California on screens all across the nation. Themost important single industry powering the growth of Los Angeles, however, was directly linked tothe automobile. The demand for petroleum to fuel gasoline engines led to the opening of theSouthern California oil fields, and made Los Angeles North America's greatest refining center.Los Angeles was a product of the auto age in another sense as well: itsdistinctive spatialorganization depended on widespread private ownership of automobiles. Los Angeles was adecentralized metropolis, sprawling across the desert landscape over an area of 400 square miles. It考博结束已经好几个月了，也终于静下心来回顾一下自己整个考博的历程。

真题集5American universities are accepting more minorities than ever. Graduating them is anothermatter.Barry Mills, the president of Bowdoin College, was justifiably proud of Bowdoin's efforts torecruit minority students. Since 2003 the small, elite liberal arts school in Brunswick, Maine, hasboosted the proportion of so-called under-represented minority students in entering freshmanclasses from 8% to 13%. "It is our responsibility to reach out and attract students to come to ourkinds of places," he told a NEWSWEEK reporter. But Bowdoin has not done quite as well whenit comes to actually graduating minorities. While 9 out of 10 white students routinely get theirdiplomas within six years, only 7 out of 10 black students made it to graduation day in severalrecent classes."If you look at who enters college, it now looks like America," says Hilary Pennington, directorof postsecondary programs for the Bill & Melinda Gates Foundation, which has closely studiedenrollment patterns in higher education. "But if you look at who walks across the stage for adiploma, it's still largely the white, upper-income population."The United States once had the highest graduation rate of any nation. Now it stands 10th. For thefirst time in American history, there is the risk that the rising generation will be less welleducated than the previous one. The graduation rate among 25- to 34-year-olds is no better thanthe rate for the 55- to 64-year-olds who were going to college more than 30 years ago. Studiesshow that more and more poor and non-white students want to graduate from college –but theirgraduation rates fall far short of their dreams. The graduation rates for blacks, Latinos,andNative Americans lag far behind the graduation rates for whites and Asians. As the minoritypopulation grows in the United States, low college graduation rates become a threat to nationalprosperity.The problem is pronounced at public universities. In 2007 the University of Wisconsin-Madison–one of the top five or so prestigious public universities –graduated 81% of its white studentswithin six years, but only 56% of its blacks. At less-selective state schools, the numbers getworse. During the same time frame, the University of Northern Iowa graduated 67% of its whitestudents, but only 39% of its blacks. Community colleges have low graduation rates generally –but rock-bottom rates for minorities. A recent review of California community colleges foundthat while a third of the Asian students picked up their degrees, only 15% of African-Americansdid so as well.27. The result of the search for an easily digestible fat turned out to be _________________ .A. commercially uselessB. just as anticipatedC. somewhat controversialD. quite unexpected28. Olestra is different from ordinary fats in that ________________ ?A. it passes through the intestines without being absorbedB. it facilitates the absorption of vitamins by the bodyC. it helps reduce the incidence of heart diseaseD. it prevents excessive intake of vitamins29.

2015年考博英语真题应用
2015年考博英语真题应用真题应用很关键考博英语对于很多考生来说，是困扰他们的一大难关。

首先，词汇是基础。
词汇是英语的基石，但是我们都知道词汇的记忆是一项很枯燥的工作，因为它要的是真功夫。
关于词汇的学习根据每个人的不同情况会有不同的方法，常见的背诵单词书、做真题记单词。
关于第一种背诵方法有两点建议：在整块背诵的基础上注意零余时间的利用，比如随身携带一本小的单词书，只要有时间就拿出来看看;关于词汇书的选择，推荐西北大学出版的《考博词汇红宝书》和《考博英语词汇速记宝典》，在记单词的过程中，把不认识的单词标记出来，并且，重新抄写到一张新的纸上，一天记一个单元或者两个单元，就有新的一张或两张纸的陌生词汇被整理出来，然后，重点记忆这些陌生词汇，效率更高。
关于第二种的背诵方法，也是得到很多同学推崇的，做真题记单词，通过语境来记忆，就是从阅读中把单词挑出来背，做一篇阅读要把时间控制在15分钟以内，做完了要花大概45分钟去弄懂，光做不研究是没有效果的。
而且要切记，词汇记忆是每天的必修课。
再说，阅读。
阅读是大头，是做好其他一切题型的基础和前提。
而且不能只是做，一定要分析每一道题，你做对了，为什么做对了?做错了，为什么错?命题的思路是什么，一定要研究透彻。
特别推崇书上说的要读文章，大声的读以培养语感，以及更深刻的理解每一篇文章，读的时候会发现看的时候没有注意到的问题，当然又一次的温习了单词。
也可以把阅读中自己感觉比较好的句型记在小本子上，为以后的写作做好积累。
一般到了九月就可以做十年真题了。
考博英语最宝贵最权威的资料就是十年真题，它有自己的出题套路，反复做反复咀嚼就能培养题感。
阅读到最后，真题都特别熟了，可以做点模拟题，测下自己的水平。

For each blank, there are four choices marked A, B, C, and D on the right side. Choose the best answer and mark the letter of your choice on the ANSWER SHEET.A mother who is suffering from cancer can pass on the disease to her unborn child in extremely rare cases 51 a new case report published in PNAS this week.According to researchers in Japan and at the Institute for Cancer Research in Sutton, UK, a Japanese mother had been diagnosed with leukemia a few weeks after giving birth 52 tumors were discovered in her daughter’s cheek and lung when she was 11 months old. Genetic analysis showed that the baby’s cancer cells had the same mutation as the cancer cellsof the mother. But the cancer cells contained no DNA whatsoever from the father 53 would be expected if she had inherited the cancer from conception. That suggests the cancer cell made it into the unborn child’s body across the placental barrier.The Guardian claimed this to be the fires 54 case of cells crossing the placental barrier. But this is not the case----microchimerism 55 cells are exchanged between a mother and her unborn child, is thought to be quite common, with some cells thought to pass from fetus to mother in about 50 to 70 percent of cases and to go the other way about half,56.As the BBC pointed out, the greater 57 in cancer transmission from mother to fetus had been how cancer cells that have slipped through the placental barrier could survive in the fetus without being killed by its immune system. The answer, in this case at least, lies in a second mutation of the cancer cells, which led to the 58 of the specific features that would have allowed the fetal immune system to detect the cells as foreign. As a result, no attack against the invaders was launched.59, according to the researchers there is little reason for concern of “cancer danger”. Only 17 probable cases have been reported worldwide and the combined 60 of cancer cells both passing the placental barrier and having the right mutation to evade the baby’s immune system is extremely low.51.

A. therefore B. furthermore C. nevertheless D. conclusively60. A. likelihood B. function C. influence D. flexibilityPart 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 on the ANSWER SHEET.Passage OneThe American Society of Clinical Oncology wrapped its annual conference this week, going through the usual motions of presenting a lot of drugs that offer some added quality or extension of life to those suffering from a variety of as-yet incurable diseases. But buried deep in an AP story are a couple of promising headlines that seems worthy of more thorough review, including one treatment study where 100 percent of patients saw their cancer diminish byhalf.First of all, it seems pharmaceutical companies are moving away from the main cost-effective one-size-first-all approach to drug development and embracing the long cancer treatments, engineering drugs that only work for a small percentage of patients but work very effectively within that group.Pfizer announced that one such drug it’s pushing into late-stage testing is target for 4% of lung cancer patients. But more than 90% of that tiny cohort responded to the drug initial tests, and 9 out of ten is getting pretty close to the ideal ten out of ten. By gearing toward more boutique treatments rather than broad umbrella pharmaceuticals that try to fit for everyone it seems cancer researchers are making some headway. But how can we close the gap on that remaining ten percent?Ask Takeda Pharmaceutical and Celgene, two drug makers who put aside competitive interests to test a novel combination of their treatments. In a test of 66 patients with the blood disease multiple myeloma, a full 100 percent response to a cancer drug(or in this case a drug cocktail) is more or less unheard of. Moreover, this combination never would’ve been two competing companies hadn’t sat down and put their heads together.Are there more potentially effective drug combos out there separated by competitive interest and proprietary information? Who’s to say, but it seems like with the amount of money and research being pumped into cancer drug development, the outcome pretty good. And if researchers can start pushing more of their response numbers toward 100 percent, we can more easily start talking about oncology’s favorite four-letter word: cure.61. which of the following can be the best title for the passage?A. Competition and CooperationB.Two Competing Pharmaceutical CompaniesC. The promising Future of PharmaceuticalsD. Encouraging News: a 100% Response to a Cancer Drug62. in cancer drug development, according to the passage, the pharmaceuticals now ____A. are adopting the cost-effective one-size-fits-all approachB. are moving towards individualized and targeted treatmentsC. are investing the lion’s shares of their moneyD. care only about their profits63. from the encouraging advance by the two companies, we can infer that____A. the development can be ascribed to their joint efforts and collaborationB. it was their competition that resulted in the accomplishmentC. other pharmaceuticals will join them in the researchD. the future cancer treatment can be nothing but cocktail therapy64. from the last paragraph it can be inferred that the answer to the question___A. is nowhere to be foundB. can drive one crazyC. can be multipleD. is conditional65. the tone of the author of this passage seems to be_____A. neutralB. criticalC. negativeD. potimistPassage TwoLiver disease is the 12th leading cause of death in the US, chiefly because once it’s determined that a patient needs a new liver it’s difficult to get one. Even in case where a suitable donor match is found, there’s guarantee a transplant will be successful. But researchers Massachusetts General Hospital have taken a huge step toward building functioning livers in the lab, successfully transplanting culture-grown livers into rats.The livers aren’t grown from scratch, but rather within the infrastructure of a donor liver. The liver cells in the donor organ are washed out with a detergent that gently strips away the liver cells, leaving behind a biological scaffold of proteins and extracellular architecture that is very hard to duplicate synthetically.With all of that complicated infrastructure already in place, the researchers then seeded the scaffold(支架) with liver cells isolated from health livers, as well as some special endothelial cells to line the bold vessels. Once repopulated with healthy cells, these livers lived in culture for 10 days.The team also translated some two-day-old recellularized livers back into rats, where they continued to thrive for eight hours while connected into the rat’s vascular systems. However, the current method isn’t perfect and can not seem to repopulate the blood vessels quite densely enough and the transplanted livers can’t keep functioning for more than about 24 hours(hence the eight-hour maximum for the rat thansplant).But the initial successes are promising, and the team thinks they can overcome the blood vessel problem and get fully functioning livers into rats within two years. It still might be a decade before the tech hits the clinic, but if nothing goes horribly wrong—and especially if stem-cell research established a reliable way to create health liver cells from the every patients who need transplants-lab-generated livers that are perfect matches for their recipients could become a reality.66. it can be inferred from the passage that the animal model was mainly intended to____A. investigate the possibility of growing blood vessels in the labB. explore the unknown functions of the human liverC. reduce the incidence of liver disease in the US.D. address the source of liver transplants67. what does the author mean when he says that the livers aren’t grown from scratch?A. the making of a biological scaffold of proteins and extracellular architectureB. a huge step toward building functioning livers in the labC. the building of the infrastructure of a donor liverD. growing liver cells in the donor organ68. the biological scaffold was not put into the culture in the lab until____A. duplicated syntheticallyB. isolated from the healthy liverC. repopulated with the healthy cellsD. the addition of some man-made blood vessels69. what seems to be the problem in the planted liver?A. the rats as wrong recipientsB. the time point of the transplantationC. the short period of the recellularizationD. the insufficient repopulation of the blood vessels70. the research team holds high hopes of_____A. creating lab-generated livers for patients within two yearsB. the timetable for generating human livers in the labC. stem-cell research as the future of medicineD. building a fully functioning liver into ratsPassage ThreePatients whose eyes have suffered heat or chemical bums typically experience severe damage to the cornea—the thin, transparent front of the eye that refracts light and contributes most of the eye’s focusing ability. In a long-term study, Italian researchers use stem cells taken from the limbus, the border between the cornea and the white of the eye, to cultivate a graft of healthy cells in a lab to help restore vision in eyes. During the 10-years study, the researchers implanted the healthy stem cells into the damaged cornea in 113 eyes of 112 patients. The treatment was fully successful in more than 75 percent of the patients, and partially successful in 13 percent. Moreover, the restored vision remained stable over 10 years. Success was defined as an absence of all symptoms and permanent restoration of the cornea.Treatment outcome was initially assessed at one year, with up to 10 years of follow-up evaluations. The procedure was even successful on several patients whose bum injuries had occurred years earlier and who had already undergone surgery.Current treatment for burned eyes involves taking stem cells from a patient’s healthy eye, or from the eyes of another person, and transferring them to the burned eye. The new procedure, however, stimulates the limbal stem cells from the patient’s own eye to reproduce in a lab culture. Several types of treatments using stem cells have proven successful in restoring blindness, but the long-term effectiveness shown here is significant. The treatment is only for blindness caused by damage to the cornea; it is not effective for repairing damaged retinas or optic nerves.Chemical eye burns often occur in the workplace, but can also happen due to mishaps involving household cleaning products and automobile batteries.The result of the study, based at Italy’s University of Modena and Reggio Emilia, were published in the June 23 online issue of the New England Journalof Medicine.71. what is the main idea of this passage?A. stem cells can help restore vision in the eyes blinded by bums.B. the vision in the eyes blinded by bums for 10 years can be restoredC. the restored vision of the burned eyes treated with stem cells can last for10 yearsD. the burned eyes can only be treated with stem cells from other healthy persons72. the Italian technique reported in this passage_____A. can repair damaged retinasB. is able to treat damaged optic nervesC. is especially effective for burn injuries in the eyes already treated surgicallyD. shows a long-term effectiveness for blindness in vision caused by damage to cornea73. which of the following is NOT mentioned about eye bums?A. the places in which people workB. the accidents that involve using household cleaning productsC. the mishaps that involved vehicles batteriesD. the disasters caused by battery explosion at home74. what is one of the requirements for the current approach?A. the stem cells taken from a healthy eyeB. the patient physically healthyC. the damaged eye with partial visionD. the blindness due to damaged optic nerves75. which of the following words can best describe the author’s attitude towards the new method?A. sarcasticB. indifferentC. criticalD. positivePassage FourHere is a charming statistic: divide the us by race, sex and county of residence, and differences in average life expectancy across the various groups can exceed 30 years. The most disadvantaged look like denizens of a poor African country: a boy born on a Native American reservation in Jackson County, South Dakota, for example, will be lucky to reach his 60th birthday, a typical child in Senegal can expect to live longer than that.America is not alone in this respect. While the picture is extreme in other rich nations, health inequalities based on race, sex and class exist in most societies—and are only party explained by access to healthcare.But fresh insights and solutions may soon be at hand. An innovative project in Chicago to unite sociology and biology is blazing the trail(开创), after discovering that social isolation and fear of crime can help to explain the alarmingly high death rate from breast cancer among the city’s black women. Living in these conditions seems to make tumors more aggressive by changing gene activity, so that cancer cells can use nutrients more effectively.We are already familiar with the lethal effect of stress on people clinging to the bottom rungs of the societal ladder, thanks to pioneering studies of British civil servants conducted by Michael Marmot of University College London. What’s exciting about the Chicago project is that it both probes the mechanisms involved in a specific disease and suggests precise remedies that it both probes the mechanisms invlilved in a specific disease and suggests precise remedies. There are drugs that may stave tumors of nutrients and community coordinators could be employed to help reduce social isolation. Encouraged by the US National Institutes of Health , similar projects are springing up to study other pockets of poor health, in populations ranging from urban black men to while poor women in rural Appalachia.To realize the full potential of such projects, biologists and sociologists will have to start treating one other with a new respect and learn how to collaborate outside their comfort zones. Too many biomedical researchers still take the arrogant view that sociology is a “soft science” with little that’s serious to say about health. And too many sociologists reject any biological angle—fearing that their expertise will be swept aside and that this approach will be used to bolster discredited theories of eugenics, or crude race-based medicine.It’s time to drop these outdated attitudes and work together for the good of society’s most deprived members. More important, it’s time to use this fusion of biology and sociology to inform public policy. This endeavor has huge implications, not least in cutting the wide health gaps between blacks and whites, rich and poor.76. as shown in the 1st paragraph, the shaming statistic reflects______.A. injustice everywhereB. racial discriminationC. a growing life spanD. health inequalities77. which of the following can have a negative impact on health according to the Chicago-based project?A. where to liveB. which race to belong toC. how to adjust environmentallyD. what medical problem to suffer78. the Chicago-based project focuses its management on_____A. a particular medical problem and its related social issueB. racial discrimination and its related social problemsC. the social ladder and its related medical conditionsD. a specific disease and its medical treatment79. which of the following can most probably neglected by sociologists?A. the racial perspectiveB. the environmental aspectC. the biological dimensionD. the psychological angel80. the author is a big fan of______A. the combination of a traditional and new way of thinking in promoting healthB. the integration of biologists and sociologists to reduce health inequalitiesC. the mutual understanding and respect between racesD. public education and health promotionPassage FiveAmerican researchers are working on three antibodies that many mark a new step on the path toward an HIV vaccine, according to a report published online Thursday, July 8,2010, in the journal Science.One of the antibodies suppresses 91 percent of HIV strains, more than any AIDS antibody ever discovered, according to a report on the findings published in the Wall Street Journal. The antibodies were discovered in the cells of a 60-year-old African-American gay man whose body produced them naturally. One antibody in particular is substantially different from its precursors, the Science study says.The antibodies could be tried as a treatment for people already infected with HIV, the WSJ reports. At the very least, they might boost the efficacy of current antiretroviral drugs.It is welcome news for the 33 million people the United Nations estimated were living with AIDS at the end of 2008.The WSJ outlines the painstaking method the team used to find the antibody amid the cells of the African—American man, known as Donor 45. First they designed a probe that looks just like a spot on a particular molecule on the cells that HIV infects. They used the probe to attract only the antibodies that efficiently attack that spot. They screened 25 million of Donor 45’s cell to find just 12 cells that produced the antibodies.Scientists have already discovered plenty of antibodies that either don’t work at all or only work on a couple of HIV strains. Last year marked the first time that researchers found ”broadly neutralizing antibodies”, which knock out many HIV strains. But none of those antibodies neutralized more than about 40 percent of them, the WSJ says. The newest antibody, at 91 percent neutralization , is a marked improvement.Still, more work needs to be done to ensure the antibodies would activate the immune system to produce natural defenses against AIDS, the study authors say. They suggest there test methods that blend the three new antibodies together—in raw form to prevent transmission of the virus, such as from mother to child; in a microbicide gel that women or gay men could use before sex to prevent infection; or as a treatment for HIV/AIDS, combined with antiretroviral drug.If the scientists can find the right way to stimulate production of the antibodies, they think most people could produce then, the WSJ says.81. we can learn from the beginning of the passage that_______A. a newly discovered antibody defeats 91% of the HIV strainsB. a new antiretroviral drug has just come on the marketC. American researchers have developed a new vaccine for HIVD. the African—American gay man was cured of this HIV infection82. what is the implication of the antibodies discovered in the cells of the African—American gay man?A. they can cure the 33 million AIDS patients in the worldB. they may strengthen the effects of the existing antiretroviral drugsC. they will kill all the HIV virusesD. they will help make a quick diagnosis of an HIV infection83. the newest antibody found in Donor 45 reflects a dramatic advance in terms of_____.A. pathologyB. pharmacologyC. HIV neutralizationD. HIV epidemiology84. according to the study authors, the three test methods are intended to____.A. advance the technology in condom production to prevent HIV infectionB. facilitate the natural immune defense against AIDSC. develop more effective antiretroviral drugs85. the passage is most likely_____.A. a news reportB. a paper in ScienceC. an excerpt from an Immunology TextbookD. an episode in a science fiction novel.Passage SixWhitening the world's roofs would offset the emissions of the world's cars for 20 years, according to a new study from Lawrence Berkeley National Laboratory.Overall, installing lighter-colored roofs and pavement can cancel the heat effect of two years of global carbon dioxide emissions, Berkeley Lab says. It's the first roof-cooling study to use a global model to examine the issue.Lightening-up roofs and pavement can offset 57 billion metric tons of carbon dioxide, about double the amount the world emitted in 2006, the study found. It was published in the journalEnvironmental Research Letters.Researchers used a conservative estimate of increased albedo, or solar reflection, suggesting that purely white roofs would be even better. They increased the albedo of all roofs by 0.25 and pavement by 0.15. That means a black roof, which has an albedo of zero, would only need to be replaced by a roof of a cooler color -- which might be more feasible to implement than a snowy white roof, Berkeley Lab says.The researchers extrapolated a roof's CO2 offset over its average lifespan. If all roofs were converted to white or cool colors, they would offset about 24 gigatons (24 billion metric tons) of CO2, but only once. But assuming roofs last about 20 years, the researchers came up with 1.2 gigatons per year. That equates to offsetting the emissions of roughly 300 million cars, all the cars in the world, for 20 years.Pavement and roofs cover 50 to 65 percent of urban areas, and cause a heat-island effect because they absorb so much heat. That's why cities aresignificantly warmer than their surrounding rural areas. This effect makes it harder -- and therefore more expensive -- to keep buildings cool in the summer. Winds also move the heat into the atmosphere, causing a regional warming effect.Energy Secretary Steven Chu, a Nobel laureate in physics (and former Berkeley Lab director), has advocated white roofs for years. He put his words into action Monday by directing all Energy Department offices to install white roofs.

二、联系导师：在初步定好考博学校之后，就要和所报考院校中意的老师取得联系，询问是否有招生名额，能否报考，这是我们考博成功的关键第一步。
大多数考生会在九月中下旬与导师取得联系。
因为太早，学校里面直博名额什么的还没有确定，报考的导师也不清楚是否有名额；太晚的话，怕别的学生比你早联系就不好了。
一般情况下，导师育明考博2014届学员成绩喜报 英语各类课程学员数873人 专业课各类课程学员239人 专业课教学测评中学员零差评 英语一对一全程32名学员全部过线 第七期考博英语集训营四个班97名学员90人过线对一个学生很中意的话，后来联系的学生，导师一般也不会答应其报考了。
在此说点题外话，联系导师的过程中，如果读研期间的导师有关系，可以尽量利用。
如果没有，也没关系，凭着自己的本事也是可以和考博导师很好的沟通的，这就要看自己了。
通常跟导师初次联系，都是发邮件。
导师回复邮件的情况一般有几种：（1）、欢迎报考。
这种答复最笼统，说明不了问题。
我们可以接着努力和老师多沟通，看看具体的进展，避免出现初试之后却没有名额的情况。
（2）、名额有限，可以报考，但有竞争。
很多人说这样的回复不满意，认为希望很小一般会被刷。
其实这样还是比较好的一种回答，最起码导师没有骗你而且给你机会去证明自己，考的好就可以上。
(3）、你的研究方向和我一样......各种一大堆他的研究方向和你相关，欢迎报考什么的话。
北京师范大学考博英语翻译试题及其解析
北京师范大学考博英语翻译试题及其解析Investigators of monkey’s social behavior have always been struckby monkeys’aggressive potential and the consequent need for socialcontrol of their aggressive behavior.Studies directed at describingaggressive behavior and the situations that elicit it,as well as thesocial mechanisms that control it,were therefore among the firstinvestigations of monkeys’social behavior.Investigators initially believed that monkeys would compete forany resource in the environment:hungry monkeys would fight over food,thirsty monkeys would fight over water,and,in general,at time morethan one monkey in a group sought the same incentive simultaneously,a dispute would result and would be resolved through some form ofaggression.However,the motivating force of competition for Geng duoyuan xiao wan zheng kao bo ying yu zhen ti ji qi jie xi qing lian xiquan guo mian fei zi xun dian hua:si ling ling liu liu ba liu jiuqi ba,huo jia zi xun qq:qi qi er liu qi ba wu san qi incentives beganto be doubted when experiments like Southwick’s on the reduction ofspace or the withholding of food failed to produce more than temporaryincreases in intragroup aggression.Indeed,food deprivation not onlyfailed to increase aggression but in some cases actually resulted indecreased frequencies of aggression.Studies of animals in the wild under conditions of extreme fooddeprivation likewise revealed that starving monkeys devoted almostall available energy to foraging,with little energy remaining foraggressive interaction.Furthermore,accumulating evidence fromlater studies of a variety of primate groups,for example,the study conducted by Bernstein,indicates that one of the most potent stimuli for eliciting aggression is the introduction of an intruder into an organized group.Such introductions result in far more serious aggression than that produced in any other types of experiments contrived to produce competition.These studies of intruders suggest that adult members of the same species introduced to one another for the first time show considerable hostility because,in the absence of a social order,one must be established to control interanimal relationships.When a single new animal is introduced into an existing social organization,the newcomer meets even more serious aggression.Whereas in the first case aggression establishes a social order,in the second case resident animals mob the intruder,thereby initially excluding the new animal from the existing social unit.The simultaneous introduction of several animals lessens the effect,if only because the group divides its attention among the multiple targets.If,however,the several animals introduced a group constitute their own social unit,each group may fight the opposing group as a unit;but,again,no individual is subjected to mass attack,and the very cohesion of the groups precludes prolonged individual combat.The submission of the defeated group,rather than unleashing unchecked aggression on the part of the victorious group,reduces both the intensity and frequency of further attack.Monkey groups therefore seem to be organized primarily tomaintain their established social order rather than to engage in hostilities per se.1.The author of the text is primarily concerned with[A]advancing a new methodology for changing a monkey’s social behavior.[B]comparing the methods of several research studies on aggression among monkeys.[C]explaining the reasons for researcher’s interest in monkey’s social behavior.[D]discussing the development of investigators’theories about aggression among monkeys.2.Which of the following best summarizes the findings reported in the text about the effects of food deprivation on monkeys’behavior?[A]Food deprivation has no effect on aggression among monkeys.[B]Food deprivation increases aggression among monkeys because one of the most potent stimuli for eliciting aggression is the competition for incentives.[C]Food deprivation may increase long-term aggression among monkeys in a laboratory setting,but it produces only temporary increase among monkeys in the wild.[D]Food deprivation may temporarily increase aggression among monkeys,but it also leads to a decrease in conflict.3.The text suggests that investigators of monkeys’socialbehavior have been especially interested in aggressive behavior among monkeys because[A]aggression is the most common social behavior among monkeys.[B]successful competition for incentives determines the social order in a monkey group.[C]situation that elicit aggressive behavior can be studied in a laboratory.[D]most monkeys are potentially aggressive,yet they live in social units that could not function without control of their aggressive impulses.4.The text supplies information to answer which of the following questions?[A]How does the reduction of space affect intragroup aggression among monkeys in an experimental setting?[B]Do family units within a monkey social group compete with other family units for food?[C]What are the mechanisms by which the social order of an established group of monkeys controls aggression within that group?[D]How do monkeys engaged in aggression with other monkeys signal submission?5.Which of the following best describes the organization of the second paragraph?[A]A hypothesis is explained and counter evidence is described.[B]A theory is advanced and specific evidence supporting it iscited.[C]Field observations are described and a conclusion about their significance is drawn.[D]Two theories are explained and evidence supporting each of them is detailed.[答案与考点解析]1.【答案】D【考点解析】本题是一道中心主旨题。

2015年11月7日北京学位英语考试真题答案详解-阅读理解Part ⅠReading Comprehension (30%)Jim Thorpe was a Native American. He was born in 1888 in an Indian Territory（印弟安人保护区）that is now Oklahoma. Like most Native American children then, he liked to fish, hunt, swim, and play games outdoors. (77) He was healthy and he had very little formal education. In 1950, Jim Thorpe was named the greatest American football player. He was also an Olympic gold medal winner. But Thorpe had many tragedies in his life.Jim had a twin brother who died when he was nine years old. By the time he was 16, his mother and father were also dead. Jim then went to a special school in Pennsylvania for Native American children. There, he learned to read and write and also began to play sports. Jim was poor, so he left school for two years to earn some money. During this time, he played on a baseball team. (78) The team paid him $15 a week. Soon he returned to school to complete his education. Jim was a star athlete（运动员）in several sports, including baseball, running, and football. He won many awards for his athletic ability, mainly for football. In many games, he scored all or most of the points for his team.In 1912, when Jim Thorpe was 24 years old, he became part of the U.S. Olympic team. He competed in two very difficult events: the pentathlon and the decathlon. Both require great ability and strength. The pentathlon has five track and field events, including the long jump and the 1,500-meter race. The decathlon has ten track and field events, with running, jumping, and throwing contests.People thought it was impossible for an athlete to compete in both the pentathlon and the decathlon. So everyone was surprised when Thorpe won gold medals in both events. When the King of Sweden presented Thorpe with his two gol d medals, he said, “Sir, you are the greatest athlete in the world” Thorpe was a simple and honest man. He just answered, "Thanks, King."1. From the passage we learn that Jim Thorpe was born in ____.A. IndiaB. PennsylvaniaC. OklahomaD. Sweden题干：从文章中，我们可以发现Jim Thorpe出生于哪里？答案及解析：C。

Part I ：Reading Comprehension
Directions: There are six passages in this part. Each of the passages is followed by five questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the best one and mark your answer on the ANSER SHEET. Passage 1 The human ear contains the organ for hearing and the organ for balance. Both organs involve fluid-filled channels containing hair cells that produce electrochemical impulses when the hairs are stimulated by moving fluid. The ear can be divided into three regions: outer, middle, and inner. The outer ear collects sound waves and directs them to the eardrum separating the outer ear from the middle ear. The middle ear conducts sound vibrations through three small bones to the inner ear. The inner ear is a network of channels containing fluid that moves in response to sound or movement. To perform the function of hearing, the ear converts the energy of pressure waves moving through the air into nerve impulses that the brain perceives as sound. Vibrating objects, such as the vocal cords of a speaking person, create waves in the surrounding air. These waves cause the eardrum to vibrate with the same frequency. The three bones of the middle ear amplify and transmit the vibrations to the oval window, a membrane on the surface of the cochlea, the organ of hearing. Vibrations of the oval window produce pressure waves in the fluid inside the cochlea. Hair cells in the cochlea convert the energy of the vibrating fluid into impulses that travel along the auditory nerve to the brain. The organ for balance is also located in the inner ear. Sensations related to body position are generated much like sensations of sound. Hair cells in the inner ear respond to changes in head position with respect to gravity and movement. Gravity is always pulling down on the hairs, sending a constant series of impulses to the brain.

浩雨：用心做好每一个 When the position of the head changes--as when the head bends forward--the force on the hair cells changes its output of nerve impulses. The brain then interprets these changes to determine the head’s new position. 1.What can be inferred about the organs for hearing and ba1ance? A. Both organs evo1ved in humans at the same time. B. Both organs send nerve impu1ses to the brain. C. Both organs contain the same amount of f1uid. D. Both organs are 1ocated in the ear's mi dd1e region. 2. Hearing involves all of the following EXCEPT______. A. motion of the vocal cords so that they vibrate. B. stimulation of hair cells in fluid-filled channels. C. amplification of sound vibrations. D. conversion of wave energy into nerve impulses. 3. It can be inferred from paragraphs 2 and 3 that the cochlea is a part of______. A. the outer ear B. the eardrum C. the middle ear D. the inner ear 4. What can be inferred from paragraph 4 about gravity? A. Gravity has an essential role in the sense of balance. B. The ear converts gravity into sound waves in the air. C. Gravity is a force that originates in the human ear. D. The organ for hearing is not subject to gravity. 5.遗失
