2009全国硕士研究生入学考试英语试题Text 2It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom – or at least confirm that he’s the kid’s dad. All he needs to do is shell our $30 for paternity testing kit (PTK) at his loca l drugstore – and another $120 to get the results.More than 60,000 people have purchased the PTKs since they first become available without prescriptions last years, according to Doug Fog, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests Directly to the public , ranging in price from a few hundred dollars to more than $2500.Among the most popular : paternity and kinship testing , which adopted children can use to find their biological relatives and latest rage a many passionate genealogists-and supports businesses that offer to search for a family’s geographic roots .Most tests require collecting cells by webbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA.But some observers are skeptical, “There is a kind of false precision being hawked by people claiming they are doing ancestry testing,” says Trey Duster, a New Y ork University sociologist. He note s that each individual has many ancestors-numbering in the hundreds just a few centuries back. Y et most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father’s line or mitochondrial DNA, which a passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents.Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don’t rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.26.In paragraphs 1 and 2 , the text shows PTK’s ___________.[A]easy availability[B]flexibility in pricing[C] successful promotion[D] popularity with households27. PTK is used to __________.[A]locate one’s birth place[B]promote genetic research[C] identify parent-child kinship[D] choose children for adoption28. Skeptical observers believe that ancestry testing fails to__________.[A]trace distant ancestors[B] rebuild reliable bloodlines[C] fully use genetic information[D] achieve the claimed accuracy29. In the last paragraph ,a problem commercial genetic testing faces is __________.[A]disorganized data collection[B] overlapping database building30. An appropriate title for the text is most likely to be__________.[A]Fors and Againsts of DNA testing[B] DNA testing and It’s problems[C]DNA testing outside the lab[D] lies behind DNA testing。

The MP3 players themselves posed no threat to pacemakersand defibrillators, used to normalize heart rhythm. But strong little magnets inside the headphones can foul即the devices if placed within 1.2 inches of them, the researchers told an American Heart Association meeting in New Orleans．Dr. William Maisel of the Medical Device Safety Institute in Boston led a team that tested eight models of MP3 player headphones，including clip-on and ear-plug types, in 60 defibrillator and pacemaker patients．They placed the headphones on the patients' chests，directly over the devices．The headphones interfered with the heart devices in about a quarter of the patients⼀14 of the 60⼀and interference was twice as likely in those with a defibrillator than with a pacemaker. Another study presented at the meeting showed that cellular phones equipped with wireless technology known as Bluetooth are unlikely to interfere with pacemakers.A pacemaker sends electrical impulses to the heart to speed up or slow heart rhythm. The magnet, however, couldmake it deliver a signal no matter what the heart rate is, the researchers said.An implantable defibrillator signals the heart to normalize its rhythm if it gets too fast or slow. A magnet couldde-activate it, making it ignore an abnormal heart rhythm instead of delivering an electrical shock to normalize it.The devices usually go back to working the right way after the headphones are removed, the researchers said."The main message here is: it's fine for patients to use their headphones normally, meaning the⼣can listen to music and keep the headphones in their ears．But what they should not do is put the headphones near their device,，，Maisel said in a telephone interview.So that means people with pacemakers or defibrillators should not place the headphones in a shirt pocket or coat pocket near the chest when they are not being used, and should not place them over their chest or have others who are wearing headphones rest their head on the patient's chest, Maisel said.51. How can MP3 digital music players hinder pacemakers and defibrillators?A. P3 players can interfere with heart pacemakers and defibrillators．B. The magnets inside the headphones can interfere with pacemakers and defibrillators．C. The loud music beats pose a threat to pacemakers and defibrillators．D. MP3 players are placed too close to pacemakers and defibrillators．52. Dr. William Maisel’s tests showed that ___________.A. headphones had interference with the heart devices in every patientB. half of the models of MP3 player headphones had interference with heart devicesC. headphones had much stronger interference with a defibrillator than with a pacemakerD. headphones had much stronger interference with a pacemaker than with a defibrillator53．Bluetooth is mentioned as an example of cell phones that _____________.A. have little interference with the heart devicesB. are used in the tests in Dr. William Maisel’s studyC. are equipped with wireless technologyD. will replace the MP3 player headphones54. The magnets inside the headphones can cause problems by _________.A. sending out electrical shock to damage heartsB. sending out signals to make hearts beat too slowC. seeding out signals to make hearts beat too fastD. making the heart devices malfunction55. People with pacemakers or defibrillators should __________.A. never use MP3 digital music playersB. not use MP3 headphonesC. not use the headphones near their heartsD. put the headphones in a pocket when they are not being used56. The writer’s purpose in writing this article is to ___________.A. report the effects of cell phones on heartsB. warn people not to use modern gadgetsC. compare different headphone productsD. inform people of the safe use of MP3 playersPassage TwoCyber crime is likely to bring about as much destruction as the credit crisis in the coming years if international regulation is not improved, some of the world’s top crime experts said Damage caused by cyber crime is estimated at $100 billion annually, said Kilian Strauss, of the Organization for Security and Cooperation in Europe (OSCE)．"These criminals outsmart us ten, or a hundred to one,，，Strauss told Reuters, adding more Internet experts were needed to investigate and tackle cyber crime.Criminal organizations are exploiting a regulatory vacuum to commit Internet crimes such as computer spying, money-laundering and theft of personal information, and the scope for damage is vast, experts told a European Economic Crime conference in Frankfurt. "We need multilateral understanding, account and oversight to avoid, in the years to come, a cyber crisis equivalent to the current financial crisis,”Antonio Maria Costa, Executive Director of the United Nations Office on Drugs and Crime, said.Internet crime is also a threat to national security, they said. Several countries, including the United States, have voiced concern over some hackers’ abilities to electronically spy on them’and disrupt computer networks．Calls for greater regulation of the Internet come at a time of regulatory renaissance, with policymakers looking to support the powers of financial sector watchdogs in the wake of the global financial crisis．"Because of the transnational nature of identity-related crime, and especially of cyber-crime, if we do not tackle the crime everywhere we will not solve it anywhere,” Costa said. The President of Interpol, Khoo Boon Hui, said increasingly highly technological gangs from Asia, Eastern Europe and Africa ～coming up with ever～sophisticated ways of swindling money from vulnerable people. He also said there was a trend of company bosses being bribed by fraudsters claiming to have guilty evidence about their firms.Strauss, who works as Senior Program Officer at the Office of the Coordinator of OSCE Economic and Environmental activities, said Internet crime watchdogs could learn a lot from criminals willing to switch sides．57. The main idea of the passage is that _________.A. cyber crime is as destructive as the credit crisis in the coming yearsB. damage caused by cyber crime is very serious and will get worseC. to fight cyber crime requires enhanced international regulationD. international organizations should be established to crush cyber crime58. According to Kilian Strauss, _____________.A. cyber criminals are 10 or 100 times smarter than Internet expertsB. Internet exerts are 10 or 100 times smarter than cyber criminalsC. as cyber criminals are very smart, more experts are needed to light against themD. the investigation of the cyber crime takes time and money59. Criminal organizations can commit internet crimes because _________.A. there is no effective regulationB. they can exploit the present regulationsC. no country has paid enough attention to themD．the current financial crisis has put the authorities at a loss60. To win the war against cyber crime; __________.A. policymakers should support their governments financiallyB. each country should solve its own problems effectivelyC. United States should play a very important roleD, international cooperation is crucial61. The underlined word swindling (in the 5th paragraph) is closest in meaning to “_______”.A. bribingB. cheatingC. corruptingD. robbing62. Straus believes that ___________.A. Internet security experts can learn a lot from cyber criminalsB. if cyber criminals will cooperate with the police, they can be helpfulC. Internet crime watchdogs will make cyber criminals shift groundsD. international」organizations can solve the problems of cyber crimePassage ThreeIt's hard to know who to trust these days．When we see people staging protests we think, Wow！These folks are passionate about their cause⼀otherwise, why would they stand in the rain for hours？But sometimes it's a show: You and even your Congressman may have been raised to power by manipulative marketers who pay serious money to hire protesters.It's a mean trick. Let's say you want to stage a political rally, but you just can't find enough people for a good turnout. What you need are folks with lots of time on their hands, who can be persuaded to make a fuss over almost anything. Solution: Head down to a homeless shelter and take out cash.No joke⼀hiring the homeless is catching on. Last October, a Georgia activist pushing a state law to crack down on illegal immigrants paid 14 homeless men ＄10 each to hold signs and march around. It worked. People thought the rally was genuine⼀a local radio station even broadcast it live. But listeners had no idea this was just a crowd for hire.Pay for rage works⼀the homeless get a little income and the lobbying group gets a crowd. The only losers are citizens and. the media, who think the whole show is legitimate. After 'a Phoenix TV station recently noticed rallies featuring the homeless, they asked some of the protesters, who were holding signs about a local labor dispute, what they were upset about. Many had no idea. "All we do is stand out here and hold the signs，，’said one.Some bold organizers have been known to "borrow'’ people's names. In one case a few years ago, members of Congress were swamped with telegrams about a telecom bill. But some constituents were confused when they got phone calls from their concerned Congressmen⼀because they'd never written in to begin with. It turned out that thousands of the telegrams were faked by a telecom-industry PR firm. And guess what? No aspect of this campaign appears to have violated Postal Service regulations．That means your name could be used next in support of a corporate cause you've never heard of. All of this amounts to a corruption of our democratic system: You can't trust someone who's calling you about a political issue, and if you write to your Congressman, he might not trust that you haven't been manipulated.Maybe the solution starts with unmasking all those protest rallies that are just outrage-for-hire purchased down at the local shelter.63. From the first paragraph it can be learned that _________.A. those protesting in the cold rain are respectableB. most Congressmen were elected by fake votesC. in come cases protesters are hiredD. people staging protests are passionate64. Which of the following statements is true？A. The homeless tend to organize protests and rallies．B. Political rallies are sometimes manipulated by power and money.C. The homeless are to blame for deceiving the public and media.D. Political rallies attended by the homeless are on the decline.65．The passage implies that sometimes _________.A. people were deceived into believing that this was a real and legal rallyB. the hired protesters. knew clearly what they were pushing forC. such protests have never attracted any attentionD. organizers paid generously for these protesters66. The underlined sentence in Paragraph 4 "pay for rage works" means that _________.A. organizers of such rallies have to pay the participantsB. expressing anger can lead to good solutionsC. the homeless have to be paid moreD. hiring people to show your outrage is effective67. To shape the Congressmen's opinion, a telecom-industry PR firm ___________.A. asked the constituents to send telegrams to the CongressmenB. wrote to local residents for supportC. tried to violate Postal Service regulationsD. sent telegrams to the Congressmen in the names of local constituents68. Protest rallies of this kind might result in ___________.A. business deceptionsB. disappearance of political trustC. the increase of the homelessD. the collapse of a political partyPassage FourIt had been a long, brutal day on the sales floor for young Brent. He'd had his share of "ups"-what retail salespeople say when it's their turn with the next customer-and more than his share of downs．And now he was in danger of being shut out for the day.He hadn't been shut out in a long rime. Even in his early days with the company, he could always sell something to someone. He was a natural. But not on this day. This，of course, exposed him to some good-natured ridicule from his associates，who took not-so-secret delight in seeing the sales genius get his stroke of misfortune.Brent had more at stake here than just professional pride and reputation, however. Brent was a new father: He and his wife,Kay, had decided that she would be a full-time mom, which meant he would financially support the family. When he did well on the sales floor, finances weren't a problem. But when he struggled to make sales，the whole family struggled.Toward the end of the day, a man came in to buy a suit. This was potentially a good sale, the kind that can turn a bad day into a good one-just like that. Brent worked hard to make the sale. But the man hesitated. Brent knew all too well the look he saw in his eyes-the look of a customer about to walk out the door empty-handed. When it became clear that the man was going to leave to do a little comparison shopping, Brent handed him his business card and invited him to return after he'd had a chance to look around.The man looked at Brent's card, then took a long look at Brent."So you're Brent's boy," the man said, referring to the card that identified him as Brent Jr."Do you know my dad?" Brent asked.“Sure do," the man said. T hey chatted for a moment, establishing the link between father and son. Then the man said, "Your dad's a good man. If you're anything like him…well, tell me again about that suit."Brent called his father that night, but not to recount the story. "I just wanted to thank you," he said, "for giving me a name I can be proud of."69. We can learn from Paragraph 2 that as a salesman Brent was ___________.A. creativeB. hard-workingC. experiencedD. warm-hearted70. Th e underlined words “stroke of misfortune" in Paragraph 3 are closest in meaning to ________.A. change of fateB. bad luckC. a rare opportunityD. an unexpected reward71. It is known from the passage that ____________.A. Brent's family had to struggle to make ends meetB. Brent's family had to experience a temporary hard timeC. the family's future depended on Brent and his wife keeping their jobsD：the family's well-being was closely related to Brent's sales performance72. As soon as the man entered the store to buy a suit,＿·A. Brent felt that his chance finally cameB ．Brent decided to chat with him for a whileC. Brent gave him his greeting and business cardDent was sure that he couldn'‘make the sale73．Brent made a call to his father because heA. had had a good day on the sales floorB ．had met an old friend of his father’s earlier in the day·'E}-s proud of his～’s achievementD. was grateful for having a respectable name74. We can learn from the story that＿．A. we should cherish what we havekey to success is to never give即C. it is important to have a good reputationD. our family is the most valuable treasurePassage FiveIf the universality of immersion-style language programs, emergency test prep classes, tired college kids is any indication, cramming（临时抱佛脚）is a wildly popular study strategy. Professors frown upon it yet conspire by squeezing vast topics like "Evolution" or "World history 1914 to present" into the last week of a course. So is cramming effective or not? A new study by UC-San Diego psychologists confirms what you may suspect deep down: The answer is no. Hurried memorization is a ．hopeless approach for retaining information. But it's not all bad news. The team offers a precise formula for better study habits, arid it doesn't necessarily need dogged discipline and routine.To arrive at their prescription, the scientists tested the "spacing effect" on long-term memory. In other words，they wanted to know how the time gap between study sessions influences the ability to remember material on test day. They asked 1,354 volunteers to memorize 32 trivial facts, such as "Who invented snow golf?" (Rudyard Kipling) and "What European nation consumes the most spicy Mexican food?" (Norway)．Participants reviewed the answers anywhere from several minutes to several months after first learning them, and then～tested up to a year later.The findings？Students perform better when they space their study sessions rather than when they try to cram everything into th eir heads during one sitting.’ But for those who must cram, timing is everything. According to the researchers, if you have only one date on which to study, choose a day that's closer to when you first learned the material than when you take the test-but not too close. For instance, if you have a French lesson on Monday and a quiz the following· Monday, you should study on Wednesday for maximum retention. Tuesday is too early and Sunday is too late. If you want to remember something for a year, wait about a month to review what you learned.Hal Pashler, one of the lead authors, suspects that most crammers don't realize the error of their ways．"Even in the scientific community, cram type summer courses on new research methods are extremely popular," he told me in ⼏an email.‘`And I have never heard people who take these courses even notice the fact that they are a perfect prescription for rapid forgetting．”75．Which of the following can best describe professors，attitude towardcramming？A. Rationally rejecting．13}.,Xeasonably ignoring.C ．Readily accepting. D．Reluctantly helping.76．The new study on cramming＿·AV&kes us confused about how to understand“B ．proves the correctness of the general understandingC，points out the problems with what's popularly knownD ．raises questions as to what should be avoided77．Paragraph 2 mainly describes＿．A. the necessity of the testB. the procedure of the testC. the selection of the test subiectsVIC content of the test questions78．According to the passage,. the most important cramming strategy is。

文章第一段第一句就点名了文章中心，接着引用自然杂志上描述的实验论证这一观点。
从第二、三段作者从几个方面分析了产生这种情况的原因，最后一段从动物上升到对人的思考。
二、试题具体解析1.[A]Suppose假设猜想[B]Consider考虑[C]Observe观察[D]Imagine设想【答案】B【考点】固定搭配【解析】本题考查的是“consider+名词性词组”的用法，表示“以……为例”，显然与后面的试验搭配表示以该试验为例引出下文。
选项A、D同义，故排除。
选项C代入文中与上下文不合，故答案为B。
【补充】consider在这里等同于take…(as an example)。
2.[A]tended(to)倾向于……[B]feared害怕[C]happened(to)碰巧……[D]threatened(to)威胁要去做……【答案】A【考点】动词搭配【解析】从空格后面的to可首先排除B，因为fear不与to连用。
再结合文章题材看，文章是科技类，而科技类文章中通常为了表示说话客观性并避免绝对化，往往在主谓之间加一个tend to表示语气的弱化，故本题答案为A，其他两个代入文章语义不通。
3.[A]thinner较细的[B]stabler较稳定的[C]lighter更明亮的[D]dimmer较暗的【答案】D【考点】逻辑关系【解析】空前内容谈到聪明的果蝇寿命相对普通果蝇要短，这里拿灯泡做比喻，相对应的自然是光线的暗淡，即光线暗淡的灯泡使用时间更长。
下一句也有提示：no being too bright，故答案为D。
4.[A]tendency趋向[B]advantage优势[C]inclination倾向[D]priority优先【答案】B【考点】词汇辨析【解析】前文谈到暗淡的灯泡寿命更长，接着说“不太明亮也是”，对比四个选项，只有优势语义连贯，故答案为B。

其中论证有效性分析30分。
论说文35分。
请写在答题纸指定的位置上。
56.论证有效性分析：分析下述论证中存在的缺陷和漏洞，选择若干要点，写一篇600字左右的文章，对该论证的有效性进行分析和评论。
(论证有效性分析的一般要点是：概念特别是核心概念的界定和使用是否准确并前后一致，有无各种明显的逻辑错误，论证的论据是否成立并支持结论，结论成立的条件是否充分等等。
) 哈佛大学教授本杰明·史华慈（Benjamin I.Schwartz）在二十世纪末指出，开始席卷一切的物质主义潮流将极大地冲击人类社会固有的价值观念，造成人类社会精神世界的空虚，这一论点值得商榷。
首先，按照唯物主义物质决定精神的基本原理，精神是物质在人类头脑中的反映。
因此，物质丰富只会充实精神世界，物质主义潮流不可能造成人类精神世界的空虚。
其次，后物质主义理论认为：个人基本的物质生活一旦得到满足，就会把注意点转移到非物质方面，物质生活丰裕的人，往往会更注重精神生活，追求社会公平，个人尊严等等。
