WritingReading ComprehensionThe purpose of the American court system is to protect the rights of the people. According to American law, if someone is accused of a crime, he or she is considered innocent until the court proves that the person is guilty. In other words, it is the responsibility of the court to prove that a person is guilty. It is not the responsibility of the person to prove that he or she is innocent. In order to arrest a person, the police have to be reasonably sure that a crime has been committed. The police must give the suspect the reasons why they are arresting him and tell him his rights under the law. Then the police take the suspect to the police station to “book”him. “Booking” means that the name of the person and the charges against him are formally listed at the police station. The next step is for the suspect to go before a judge. The judge decides whether the suspect should be kept in jail or released. If the suspect has no previous criminal record and the judge feels that he will return to court rather than run away—for example, because he owns a house and has a family—he can go free. Otherwise, the suspect must put up bail. At this time, too, the judge will appoint a court layer to defend the suspect if he can’t afford one. The suspect returns to court a week or two later. A lawyer from the district attorney’s office presents a case against the suspect. This is called a hearing. The attorney may present evidence as well as witnesses. The judge at the hearing then decides whether there is enough reason to hold a trial. If the judge decides that there is sufficient evidence to call for a trial, he or she sets a date for the suspect to appear in court to formally plead guilty or not guilty. At the trial, a jury of 12 people listens to the evidence from both attorneys and hears the testimony of the witnesses. Then the jury goes into a private room to consider the evidence and decide whether the defendant is guilty of the crime. If the jury decides that the defendant is innocent, he goes free. However, if he is convicted, the judge sets a date for the defendant to appear in court again for sentencing. At this time, the judge tells the convicted person what his punishment will be. The judge may sentence him to prison, order him to pay a fine, or place him on probation. The American justice system is very complex and sometimes operates slowly. However, every step is designed to protect the rights of the people. These individual rights are the basis, or foundation, of the American government.1．What is the main idea of the passage?A．The American court system requires that a suspect prove that he or she is innocent.B．The US court system is designed to protect the rights of the people.C．Under the American court system, judge decides if a suspect is innocent or guilty.D．The US court system is designed to help the police present a case against the suspect.正确答案：B解析：本文的第一段第一句话“The purpose of the American court system is to protect the fights of the people．”就点明了文章的主旨，即美国法院系统的作用是保护人民的权利，因此选择B。

【语言能力】首先，单词肯定是需要记忆方法的，通过记忆方法能快速的记住单词的字典含义；但记住单词的字典含义只是第一步，更重要的是注意在语境中调整和赋予这个单词更准确和通顺的语境含义，以帮助我们更贴切的理解文章。
比如：1.rested with字典含义：取决于...Copyright rested with the journal publisher.，and researchers seeking knowledge of the results wouldhave to subscribe to the journal.在这个句子中根据语境：版权属于期刊的出版者;2.entail字典含义是：使蒙受，使产生;必须，使承担;Deliberate practice entails more thansimply repeating a task.Rather,it involves setting specific goals,obtainingimmediate feedback and concentrating as much on technique as on outcome.这句中的entails=involves.(这句把并列连词省略了，补全是：Deliberatepractice entails more than…and it involves…)3.substantial字典含义：大量的;结实的，牢固的;重大的Genetically speaking,there are advantagesto avoiding substantial height.从基因的角度来讲，避免长的“太”高是有好处的。

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。
2015全国二卷英语真题(总7页)
2015全国二卷英语真题(总7页)AMy color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautiful when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.Then I started developing a problem with the set that involved static(静电)noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my first, and it stopped working altogether. My trip to the repair shop cost me $62and the sit is working well now, but I keep expecting more trouble.21. Why did the author say he was fooled into buying the TV set?A. He got an older model than he had expected.B. He couldn’t return it when it was broken.C. He could have bought it at a lower price.D. He failed to find any movie shows on it.22. Which of the following an best replace the phrase “signed off’ in paragraph 1?A. ended all their programsB. provided fewer channelsC. changed to commercialsD. showed all-night movies23. How did the author finally get this TV set working again?A. By shaking and hitting itB. By turning it on and offC. By switching channelsD. By having it repaired24. How does the author sound when telling the story?A. CuriousB. AnxiousC. CautiousD. HumorousBYour house may have an effect on your figure. experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights. dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they’re in poorly lit places-and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing,while cold colors make us less hungry. So when it’s ti me to repaint, go blue.Don’t forget the clock-or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. An d while you’re at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by14 percent. And we’ll pour about 30 percent more liquid intoa short, wide glass than a tall, skinny glass.25. The text is especially helpful for those who care about______.A. their home comfortsB. their body shapeC. house buyingD. healthy diets26. A home environment in blue can help people___.A. digest food betterB. reduce food intakeC. burn more caloriesD. regain their appetites27. What are people advised to do at mealtimes?A. Eat quickly.B. Play fast musicC. Use smaller spoonsD. Turn down the lights28. What can be a suitable title for the text?A.Is Your House Making You Fat?B. Ways of Serving DinnerC. Effects of Self-ConsciousnessD. Is Your Home Environment Relaxing?CMore students than ever before are taking a gap year(间隔年)before going to university. It used to be the “year off” between school and university. The gap-year phenomenon originated(起源)with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year.This year, 25,310 students who have accepted places inhigher education institutions have put off their entry until next year, according to statistics on university entrance provided by the University and College Admissions Service (UCAS).That is a record 14.7% increase in the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. “Students who take a well-planned year out are more likely to be satisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible," he said.But not everyone is happy. Owain James, the president of the National Union of Students(NUS), argued that the increase is evidence of student hardship-young people are being forced into earning money before finishing their education. “New students are now aware that they are likely to leave university up to£15,000 in debt. It is not surprising that more and more students are taking a gap year to earn money to support their study for the degree. NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacating periods," he said.29. What do we learn about the gap year from the text?A. It is flexible in length.B. It is a time for relaxationC. It is increasingly popularD. It is required by universities30. According to Tony Higgins. students taking a gap year___.A. are better prepared for college studiesB. know a lot more about their future jobC. are more likely to leave university in debtD. have a better chance to enter top universities31.How does Owain James feel about the gap-year phenomenon?A. He's puzzledB. He's worriedC. He's surprisedD. He's annoyed32.What would most students do on their vacation according to NUS statistics?A. Attend additional courses.B. Make plans for the new termC. Earn money for their educationD. Prepare for their graduate studies。

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. suggests B. suggesting C. having suggested D. suggested52. A. since B. although C. whereas D. when53. A. what B. whom C. who D. as54. A. predicted B. notorious C. proven D. detailed55.

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.

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. All newly installed roofs will be white, and black roofs might be replaced when it is cost-effective over the lifetime of the roof."Cool roofs are one of the quickest and lowest-cost ways we can reduce our global carbon emissions and begin the hard work of slowing climate change," he said in a statement.86. which of the following can be the best title for the passage?A. a Decline in Car EmissionsB. white Roofs or Black PavementsC. the Effect of Linghting-up RoofsD. climate Change and Extreme Weathers87. a indicated by the passage, black roofs______A. are better than snowy white onesB. reflect not heat from the sunC. are more expensive to build in the urban areasD. are supposed to be placed by snowy white ones88. if they are converted to white or cooler colors, all roofs in the world in their lifetime_____A. can absorb 1.2 gigattons of CO2 a yearB. could serve as 300 million cars in terms of emissionC. would offset the emissions from 300 million carsD. would offset about 24 gigatons of CO2 as emitted from the cars89. according to the passage, it is hard and expensive to keep the urban buildings cool because of______A. the heat-island effectB. the lack of seasonal windsC. the local unique weatherD. the fast urban shrinkage90. energy Secretary Steven Chu implies that_____A. nothing could be more effective in cooling global warming than method he has advocatedB. the method in question still needs to be justified in the futureC. our global carbon emissions can be reduced by half if cool roofs are installedD. weather change and global warming can be addressed in no timePart V Writing(20%)Directions: in this part there is an essay in Chinese. Read it carefully and then write a summary of 200 words in English on the ANSWER SHEET. Make sure that your summary covers the major points of the passage.什么是健康？人的健康包括身体健康和心理健康两个方面。

If their noses inhaled(吸入)a certain type of air pollution when they were pregnant. That's the finding of a new study. Released when things aren't burned completely, this pollution is known as polycyclic aromatic hydrocarbons, or PAHs. The biggest sources of these PAHs: the burning of fossil fuels, wood and trash.Frederica Perera works at Columbia University's Mailman School of Public Health is New York City. She researches how exposure to things in the environment affects children's health in a new study, she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women in New York City. Because burning tobacco can spew(排放)PAHs into the air and lungs, Perera's team focused on nonsmokers. The researchers wanted to probe(探查)other sources of PAHs, ones that's would have been hard for an individual to avoid.The team started by testing the blood of each woman during pregnancy. The reason Any PAHs in a woman's blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs of attention problems in those children, now age 9. They asked each child's mother a series of questions. These included whatever her child had problems doing things that needed sustained(长期的)mental effort, such as homework or games with friends. The scientists also asked if the kids had trouble following instructions or made frequent, careless mistakes. All of these can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder, or ADHD. About one in U.S. children has ADHD.Among the women studied, traffic and home heating were the primary sources of air pollution exposure, Perera and her team suspect. Some of these women had low levels of PAHs in their blood. Ohters had high levels. Those with high levels were five times as likely to have children who showed attention problems by age 9. The new findings were published November 5 in the journal PLOS ONE.16. Perera and her team chose nonsmoking pregnant women all over America.A. RightB. WrongC. Not mentioned17. The main purpose of the research was to find out how exposure to PAHs playeda role in harming the subjects' physical health.A. RightB. WrongC. Not mentioned18.

Not mentioned第3部分：概况大意与完成句子First Image-recognitions software1) Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.2)The new system, which was tested on photos and is now being applied to videos, shows for the first time that a machine learning algorithm(运算法则)for image recognition and retrieval is accurate and efficient enough to improve large-scale document searches online. The system uses pixel(像素)data in images and potentially video—rather than just text—to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search engines. The knowledge gleaned(收集)from those results can then be applied to otherphotos without tags or captions(图片说明),making for more accurate document search results.3)“Over the last 30 years,” says Associate Professor Korenzo Torresani, a co-author of the study,” the web has evolved from a small collection of mostly text documents to a modern, massive, fast-growing multimedia datastet, where nearly every page includes multiple pictures of videos. When a person looks at a Web page, he immediately get the gist(主旨)of it by looking at the pictures in it. Yet, surprisingly, all existing popular search engine, such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Wed pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pixels to improve document search.”4)The researchers designed and tested a machine vision system—a type of artificialintelligence that allows computers to learn without being explicitly programmed— that extracts semantic(语义的)information from pixels of photos in Web pages. This informationg is used to enrich the description of the HTML page used by search engines for document retrieval. The researchers tested their approach using more than 600 search queries(查询)on a database of 50 million Wed pages. They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages. They found tht this produced a 30 percent improvement in precision over the original search engine purely based on text.23. Paragraph 1 _____24. Paragraph 2 _____25. Paragraph 3 _____26 Paragraph 4 _____A. Popularity of the new systemB. Publication of the new discoveryC .Function of the new systemD. Artificial intelligence software createdE. Problems of the existing search enginesF .Improvement in document retrieval27. The new system does document retrieval by _____.28. The new system is expected to improve precision in _____.29. When performing document retrieval the existing search engines ignore _____.30. The new system was found more effective in document search than the _____.A. information in imagesB. current popular search enginesC. using photosD. machine vision systemsE. document searchF. description of the HTML page第四部分：阅读理解第一篇Why Buy Shade-Grown Coffee?When people argue about whether coffee is good for health, they're usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits.Unfortunately, deforesting for coffee production immediately decreaseslocal-wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it's worth it.31. What is the main idea of this passage?A. Farmers are changing the way they grow coffee.B. Coffee is becoming more expensive to produce.C. Shade-grow coffee is more expensive than sun-grow coffee.D. People should buy shade-grown coffee.32. The function of the word "Traditionally" in Paragraph 2 is to show_____.A. the positive effects of coffee.B. a change of coffee growth.C. something that is the most important.D. how coffee production used to be.33.What does increased production of full-sun coffee bring about?A. More insects.B. Better quality coffee.C. Larger farms.D. Higher profits.34. How do farmers find more land for growing full-sun coffee?A. They buy more land from other farmers.B. They cut down trees.C. They move to another country.D. They turn grassland into farmland.35.The full-sun method may affect the following EXCEPT_____ full sunA. insects.B. air.C. birdsD. humans第二篇More Rural Research is NeededAgricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer, crop scientist, said demand was growing at 2.5% per year but with modern technologies and the development of new ones, the world should be able to stay ahead.“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition(营养不良)and poverty.” he said.Research is needed to solve food production, land degradation(贫瘠化)and environmental problems. Secure local food supplies led to economic growth which is turn, slowed population growth. Dr. Fischer painted a picture of the world’s ability to feed itself in the first 25 years, when the world’s population is expected to rise from 5 X to X billion people. He said that things will probably hold or improve but there’ll still be a lot of hungry people. The biggest concentration of poorand hungry people would be in sub-Saharan Africa and southern Asia in 2020, similar to the current pattern. If there is any change, a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia, South America and South-East Asia.The developing world was investing about 0.5%, or $8 billion a year, of its agricultural gross domestic product(GDP)on research and developed world was spending 2.5% of its GDP. Dr. Fischer said more was needed from all countries.He said crop research could produce technologies that spread across many countries, such as wheat production research having spin-offs(有用的副产品)for Mexico, China or India.“Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application, so that money can be used very efficiently.” Dr. Fischer said.Yields of rice, wheat ad maize(玉米)havegrown impressively in the past 30 years, especially in developing countries. For example, maize production rose from 2 to 8 tonnes per hectare between 1950 and 1995. But technologies driving this growth such as high-yield varieties, fertilizers, and irrigation, were becoming exhausted. “If you want to save the land for non-agricultural activities, for forests and wildlife, you’re going to have to increase yield.” Dr. Fischer said.36. What is the passage mainly about?A. Shortage of food supplies.B. Development of agricultural technologies.C. Impact of agricultural research.D. Expectation of population growth.37. Which of the following statements is true about the world’s agricultural research funding?A. It is increasing among developed countries.B. It is decreasing worldwide.C. Less is demanded from developing countries.D. Most of it is spent very efficiently.38. What is the picture of Asia’s food supplies in the first 25 years?A. Food shortage will not be a problemB. There will be more hungry people in southern Asia.C. Population growth will result in more hungry people.D. There will be fewer hungry people in East Asia.39. What does Dr. Fischer say about technologies? Dr FischerA. They are costly.B. They have to be improved to meet local needs.C. Their application is limited.D. They have to be applied locally.40. It can be infered from the last paragraph that_____.A. there is a demand for saving land for non-agricultural activities.B. crop production is growing faster in developing countries.C. maize production reached its peak in the 1990s.D. technologies improving maize production have been well developed.第三篇Dangers await babies with altitudeWomen who live in the world's highest communities tend to give birth to under-weight babies, a new study suggests. These babies may grow into adults with a high risk of heart disease and strokes.Research has hinted that newborns in mountain communities are lighter than average. But it wasn't clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished — many people who live at high altitudes are relatively poor compared with those living lower down.To find out more, Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1976 and 1998. The babies were born in both rich and poor areas of two cities: La Paz and Santa Cruz. L Paz is the highest city in the world, at 3.65 kilometers above sea level, while Santa Cruz is much lower, at 0.44 kilometers.Sure enough, Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz. This was true in both high and low-income families. Even babies born to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz. "We were very surprised by this result," says Giussani.The results suggest that babies born at high altitude are deprived of oxygen before birth. "This may trigger the release or suppression of hormones that regulate growth of the unborn child," says Giussani.His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies. This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to rest of the body.Giussani wants to find out if such babies have a higher risk of disease in later life. People born in La Paz might be prone to heart trouble in adulthood, for example. Low birth weight is a risk factor for coronary(冠状的) heart disease. And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life.41. What does the new study discover?A. Babies born to wealthy families are heaver.B. Women living at high altitude tend to give birth to underweight babies.C. Newborns in cities are lighter than average.D. Low-altitude babies have a high risk of heart disease in later life.42. Giussani and his team are sure that _____.A. babies born in Lance Paz are on average lighter than in Santa Cruz.B. people living at high altitudes tend to give birth to underweight babies.C. the birth weight of babies born to wealthy families is Santa Cruz.D. mothers in La Paz are commonly under-nourished.43. It can be inferred from what Giussani says in Paragraph 4 that_____.A. the finding was unexpectedB. he was very tired.C. the study took longer than expected.D. he was surprised to find low-income families in La Paz.44. The results of the study indicate the reason for the underweight babies is _____.A. lack of certain nutrition.B. power of their mother.C. different family backgrounds.D. reduction of oxygen levels.45. It can be learned about form the paragraph that_____.A. high-altitude babies tend to have high blood pressure in later life.B. under-weight babies have a shorter life span.C. babies born to poor families lack hormones before birth.D. new born wealthy families have larger heads compared with their bodies. 第5部分：补全短文(第46～50题，每题2分，共10分)Saving a City's Public ArtAvoiding traffic jams in Los Angeles may be impossible, but the city's colorful freeway murals(壁画)can brighten even the worst commute. Paintings that depict(描述)famous people and historical scenes cover office buildings and freeway walls all access the city. With a collection of more than 2,000 murals, Los Angeles is the unofficial mural capital of the world.But the combination of graffiti(涂鸦), pollution, and hot sun has left many L.A. murals in terrible condition. _____(46)in the past, experts say, little attention was given to caring for public art. Artists were even expected to maintain their own works, not an easy task with cars racing by along the freeway._____(47)The work started in 2003. So far, 16 walls have been selected and more may be added later.Until about 1960, public murals in Los Angeles were rare. But in the 1960s and 1970s, young L.A. artists began to study early 20th-century Mexican mural painting_____(48)The most famous mural in the city is Judith Baca's "The Great Wall," a13-foot-high(4-meter-high)painting that runs for half a mile (0.8 kilometer) in North Hollywood, _____(49)it took eight years to complete—400 underprivileged teenagers painted the designs—and is probably the longest mural in the world.One of the murals that will be restored now is Kent Twitchell's "Seventh Street Altarpiece." which he painted for the Los Angeles Olympics in 1984. _____ (50) Twitchell said, "it was meant as a kind of gateway through which the traveler to L.A. must drive. The open hands represent peace."Artists often call murals the people's art. Along a busy freeway or hidden in a quiet neighborhood, murals can teach people who would never pay money to see fine art in a museum, "Murals give a voice to the silent majority," said one artist.A. The city trying to stop the spread of graffiti, has painted over some of the murals complete.B. This striking work depicts two people facing each other on opposite sides of the freeway near downtown Los Angeles.C. Artists like murals because they like the work of Mexican artists.D. Now the city is beginning a huge project to restore the city's murals.E. The mural represents the history of ethnic groups in California.F .Soon, their murals became a symbol of the city's cultural expressions and a showcase for L.A.'s cultural diversity.第6部分：完形填空I'll Be BachComposer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can't _____(51)the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Cope's computer.It all started in 1980 in the United States, when Cope was trying to write an opera. He was having _____(52)thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not_____(53)to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers, brains_____(54)like big databases. First, they take in all the music that they have ever heard.

According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.Cope built a_____(57)database of existing music. He began with hundreds of works by Bach. The software analyzed the data_____(58)it down into smaller pieces and looked for patterns. It then combined the_____(59)into new patterns. Before long, the program could compose short Bach-like works. They weren't good, but it was a start.Cope knew he had more work to do-he had a whole opera to write. He continued to improve the software. Soon it could_____(60)more complex music. He also added many other composers, including his own work to the database.A few years later, Cope's computer program, called "Emmy", was ready to help him with his opera.

cases,【C1】______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,【C2】______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 cells of the mother. But the cancer cells contained no DNA whatsoever from the father,【C3】______would be expected if she had inherited the cancer from conception. That suggests the cancer cells made it into the unborn child's body across the placental barrier. The Guardian claimed this to be the first【C4】______case of cells crossing the placental barrier. But this is not the case — microchimerism,【C5】______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 75 per cent of cases and to go the other way about half【C6】______. As the BBC pointed out, the greater【C7】______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【C8】______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. 【C9】______, according to the researchers there is little reason for concern of "cancer danger". Only 17 probable cases have been reported worldwide and the combined【C10】______of cancer cells both passing the placental barrier and having the right mutation to evade the baby's immune system is extremely low.（分数：20.00）(1).【C1】（分数：2.00）A.suggestsB.suggestingC.having suggestedD.suggested(2).【C2】（分数：2.00）A.sinceB.althoughC.whereasD.when(3).【C3】（分数：2.00）A.whatB.whomD.as(4).【C4】（分数：2.00）A.predictedB.notoriousC.provenD.detailed(5).【C5】（分数：2.00）A.whereB.whenC.ifD.whatever(6).【C6】（分数：2.00）A.as manyB.as muchC.as wellD.as often(7).【C7】（分数：2.00）A.threatB.puzzleC.obstacleD.dilemma(8).【C8】（分数：2.00）A.detectionB.deletionC.amplificationD.addition(9).【C9】（分数：2.00）A.ThereforeB.FurthermoreC.NeverthelessD.Conclusively(10).【C10】（分数：2.00）A.likelihoodB.functionC.influenceD.flexibility六、PartⅣ Reading Comprehension(总题数：6，分数：60.00)The 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 by half. First of all, it seems pharmaceutical companies are moving away from the more cost-effective one-size-fits-all approach to drug development and embracing the long tail of 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 in initial tests, and nine out often is getting pretty close to the ideal ten out of ten. By gearing drugs 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 atest of 66 patients with the blood disease multiple myeloma, a full 100 percent of the subjects saw their cancer reduced by half. Needless to say, a 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 tried if two competing companies hadn't sat down and put their heads together. Are there more potentially effective drug combos out there separated by walls of competitive interest and proprietary information? Who's to say, but it seems like with the vast amount of money and research being pumped into cancer drug development, the odds are 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.（分数：10.00）(1).Which of the following can be the best title for the passage?（分数：2.00）petition and CooperationB.Two Competing Pharmaceutical CompaniesC.The Promising Future of PharmaceuticalsD.Encouraging News: a 100% Response to a Cancer Drug(2).In cancer drug development, according to the passage, the pharmaceuticals now______.（分数：2.00）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 profits(3).From the encouraging advance by the two companies, we can infer that______.（分数：2.00）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 therapy(4).From the last paragraph it can be inferred that the answer to the question______.（分数：2.00）A.is nowhere to be foundB.can drive one crazyC.can be multipleD.is conditional(5).The tone of the author of this passage seems to be______.（分数：2.00）A.neutralB.criticalC.negativeD.optimisticLiver disease is the 12th -leading cause of death in the U. S. , chiefly because once it's determined that a patient needs a new liver it's very difficult to get one. Even in case where a suitable donor match is found, there's no guarantee a transplant will be successful. But researchers at 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 healthy 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 transplanted some two-day-old recellularized livers back into rats, where they continued to thrive for eight hours while connected into the rats' vascular systems. However, the current method isn't perfect and cannot 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 transplant). 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 establishes a reliable way to create healthy liver cells from the very patients who need transplants — lab-generated livers that are perfect matches for their recipients could become a reality.（分数：10.00）(1).It can be inferred from the passage that the animal model was mainly intended to______.（分数：2.00）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 U. S.D.address the source of liver transplants(2).What does the author mean when he says that the livers aren't grown from scratch?（分数：2.00）A.The making of a biological scaffold of proteins and extracellular architecture.B.A huge step toward building functioning livers in the lab.C.The building of the infrastructure of a donor liver.D.Growing liver cells in the donor organ.(3).The biological scaffold was not put into the culture in the lab until______.（分数：2.00）A.duplicated syntheticallyB.isolated from the healthy liverC.repopulated with the healthy cellsD.the addition of some man-made blood vessels(4).What seems to be the problem in the planted liver?（分数：2.00）A.The rats as wrong recipients.B.The time point of the transplantation.C.The short period of the recellularization.D.The insufficient repopulation of the blood vessels.(5).The research team holds high hopes of______.（分数：2.00）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 ratsPatients whose eyes have suffered heat or chemical burns 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 in several patients whose burn 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 vision, 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 results 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 Journal of Medicine.（分数：10.00）(1).What is the main idea of this passage?（分数：2.00）A.Stem cells can help restore vision in the eyes blinded by burns.B.The vision in the eyes blinded by burns for 10 years can be restored.C.The restored vision of the burned eyes treated with stem cells can last for 10 years.D.The burned eyes can only be treated with stem cells from other healthy persons.(2).The Italian technique reported in this passage______.（分数：2.00）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 cornea(3).Which of the following is NOT mentioned about eye burns?（分数：2.00）A.The places in which people work.B.The accidents that involve using household cleaning products.C.The mishaps that involve vehicles batteries.D.The disasters caused by battery explosion at home.(4).What is one of the requirements for the current approach?（分数：2.00）A.The stem cells taken from a healthy eye.B.The patient physically healthy.C.The damaged eye with partial vision.D.The blindness due to damaged optic nerves.(5).Which of the following words can best describe the author's attitude towards the new method?（分数：2.00）A.Sarcastic.B.Indifferent.C.Critical.D.Positive.Here is a shaming 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 partly 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. 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 white 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.（分数：10.00）(1).As shown in the 1st paragraph, the shaming statistic reflects______.（分数：2.00）A.injustice everywhereB.racial discriminationC.a growing life spanD.health inequalities(2).Which of the following can have a negative impact on health according to the Chicago-based project?（分数：2.00）A.Where to live.B.Which race to belong to.C.How to adjust environmentally.D.What medical problem to suffer.(3).The Chicago-based project focuses its management on______.（分数：2.00）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 treatment(4).Which of the following can most probably be neglected by sociologists?（分数：2.00）A.The racial perspective.B.The environmental aspect.C.The biological dimension.D.The psychological angel.(5).The author is a big fan of______.（分数：2.00）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 promotionAmerican 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 three 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.（分数：10.00）(1).We can learn from the beginning of the passage that______.（分数：2.00）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 his HIV infection(2).What is the implication of the antibodies discovered in the cells of the African-American gay man?（分数：2.00）A.They can cure the 33 million AIDS patients in the world.B.They may strengthen the effects of the existing antiretroviral drugs.C.They will kill all the HIV viruses.D.They will help make a quick diagnosis of an HIV infection.(3).The newest antibody found in Donor 45 reflects a dramatic advance in terms of______.（分数：2.00）A.pathologyB.pharmacologyC.HIV neutralizationD.HIV epidemiology(4).According to the study authors, the three test methods are intended to______.（分数：2.00）。

中国矿业大学考博英语真题2015年Part ⅠReading ComprehensionDirections: There are 5 passages in this part. Each passage is followed by four questions or statements. For each of them there are four choices marked A, B, C and D. Decide on the best choice and mark the corresponding letter on your Answer Sheet.Passage OneThe purpose of the American court system is to protect the rights of the people. According to American law, if someone is accused of a crime, he or she is considered innocent until the court proves that the person is guilty. In other words, it is the responsibility of the court to prove that a person is guilty. It is not the responsibility of the person to prove that he or she is innocent.In order to arrest a person, the police have to be reasonably sure that a crime has been committed. The police must give the suspect the reasons why they are arresting him and tell him his rights under the law. Then the police take the suspect to the police station to "book" him. "Booking" means that the name of the person and the charges against him are formally listed at the police station.The next step is for the suspect to go before a judge. The judge decides whether the suspect should be kept in jail or released. If the suspect has no previous criminal record and the judge feels that he will return to court rather than run away—for example, because he owns a house and has a family—he can go free. Otherwise, the suspect must put up bail. At this time, too, the judge will appoint a court layer to defend the suspect if he can't afford one.The suspect returns to court a week or two later. A lawyer from the district attorney's office presents a case against the suspect. This is called a hearing. The attorney may present evidence as well as witnesses. The judge at the hearing then decides whether there is enough reason to hold a trial. If the judge decides that there is sufficient evidence to call for a trial, he or she sets a date for the suspect to appear in court to formally plead guilty or not guilty.At the trial, a jury of 12 people listens to the evidence from both attorneys and hears the testimony of the witnesses. Then the jury goes into a private room to consider the evidence and decide whether the defendant is guilty of the crime. If the jury decides that the defendant is innocent, he goes free. However, if he is convicted, the judge sets a date for the defendant to appear in court again for sentencing. At this time, the judge tells the convicted person what his punishment will be. The judgemay sentence him to prison, order him to pay a fine, or place him on probation.The American justice system is very complex and sometimes operates slowly. However, every step is designed to protect the rights of the people. These individual rights are the basis, or foundation, of the American government.1. What is the main idea of the passage? ______A.The American court system requires that a suspect prove that he or she is innocent.B.The US court system is designed to protect the rights of the people.C.Under the American court system, judge decides if a suspect is innocent or guilty.D.The US court system is designed to help the police present a case against the suspect.答案：B[解答] 本文的第一段第一句话“The purpose of the American court system is to protect the rights of the people.”就点明了文章的主旨，即美国法院系统的作用是保护人民的权利，因此选择B。
2. What follows "In other words" (Para. 1)? ______A.An example of the previous sentence.B.A new idea about the court system.C.An item of evidence to call for a trial.D.A restatement of the previous sentence.答案：D[解答] 第一段中“In other words”后面说证明一个人是否有罪是法院的责任。
在接下来的几段中阐述了从警察逮捕嫌疑人，到法官决定是否让嫌疑人保释，再到陪审团判定是否有罪。
据此可知，“In other words”后面应是对以前宣判过程的另一种表述。
因此选择D。
3. According to the passage, "he can go free" (Para. 3) means ______.A.the suspect is free to choose a lawyer to defend himB.the suspect does not have to go to trial because the judge has decided he is innocentC.the suspect will be informed by mail whether he is innocent or notD.the suspect does not have to wait in jail or pay money until he goes to trial答案：D[解答] 本题细节定位于第三段第三、四句话“If the suspect has no previous criminal record and the judge feels that he will return to court rather than run away—for example, because he owns a house and has a family—he can go free. Otherwise, the suspect must put up bail.”。
由此可知，如果嫌疑人没有前科，法官认为他不会逃跑——例如他有房产或家庭，嫌疑人就可以被释放。
否则，嫌疑人必须支付保释金。
