1、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in ____ the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.need

B.case

C.necessity

D.time

正确答案:B

答案解析:in?case是固定用法，意思是“万一”。整个句子说的是：因此，又有了一个保存病毒的理由——万一这种病卷土重来。

2、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face ａｎｄ　George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws ａｎｄ　well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face ａｎｄ　fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate ｏｒminimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, ａｎｄ　more apt to fight, challenge bosses, cheat on spouses ａｎｄ　put less effort into parenting. Those with more feminine faces were seen as good parents ａｎｄ　husbands, hard workers ａｎｄ　emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose fｏｒa short-term relationship, women ｓｅｌｅｃｔed the more masculine ____ men. Brad ａｎｄ　George, both chiseled jaws ａｎｄ　well-defined brows, then would be good fｏｒa brief romance, not fｏｒsomething longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible fｏｒthe development of masculine facial features ａｎｄ　other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong ａｎｄ　healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to cheating ａｎｄ　violence in relationships. So, these men might produce high quality offspring, but they don\'t always make great parents ｏｒfaithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool fｏｒunderstanding mating strategies. And, of course, fｏｒexplaining why Tony Leung ａｎｄ　Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. ｏｒsomething to do with ours.【单选题】

A.seeming

B.appearing

C.looking

D.pretending

正确答案:C

答案解析:seem:好像；appear：出现；look:看上去；pretend:假装。我们可以说：These men look very masculine. 也可以说these masculine looking men,因此用looking是对的。

3、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States ａｎｄ　the United Kingdom can expect to live to about 74. Women to about 80, ａｎｄ　these ____ are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute ａｎｄ　oftenhighly infectious diseases such as smallpox. Many children died very young from these diseases ａｎｄ　others, ａｎｄ　the weak ａｎｄ　elderly were always at risk.In the developed world these diseases are far less deadly today, ａｎｄ　in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation ａｎｄ　hygiene, the discovery ａｎｄ　use of antibiotics, which make bacterial diseases much less dangerous, ａｎｄ　vaccinations against common diseases. In addition , people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better ａｎｄ　warmer housing, ａｎｄ　better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease ａｎｄ　strokes, ａｎｄ　those spread by viruses, such as influenza ａｎｄ　AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease ａｎｄ　illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】

A.ages

B.years

C.lives

D.countries

正确答案:A

答案解析:通过上下文可知此处应为“年龄”。

4、ExerciseWhether ｏｒnot exercise adds ____ the length of life, it is common experience that a certain amount of regular exercise improves the health ａｎｄ　contributes a feeling of well-being. Furthermore, exercise which involves play ａｎｄ　recreation, ａｎｄ　relieves nervous tension ａｎｄ　mental fatigue in so doing, is not only pleasant but beneficial.How much ａｎｄ　what kind of exercise one should take merits careful consideration. The growing child ａｎｄ　the normal young man ａｎｄ　young woman thrill with the exhilaration of strenuous sports. They fatigue to the point of exhaustion but recover promptly with a period of rest. But not so with those of middle age ａｎｄ　beyond. Fｏｒthem moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe fｏｒone person of forty but folly fｏｒanother. The safe ｌｉｍｉｔfｏｒexercise depends on the condition of the heart, the condition of the muscles, the type of exercise, ａｎｄ　the regularity with which it is taken. Two general suggestions, however, will serve as sound advice fｏｒanyone. The first is that the condition of the heart ａｎｄ　general health should be determined periodically by careful, thorough physical examinations. The other is that exercise should be kept below the point of physical exhaustion.What type of exercise one should choose depends upon one\'s physical condition. Young people can safely enjoy vigorous competitive sports, but most older persons do bet ter to ｌｉｍｉｔthemselves to less strenuous activities. Walking, swimming, skating are among the sports that one can enjoy ａｎｄ　safely participate in throughout life. Regularity is important if one is to get the most enjoyment ａｎｄ　benefit out of exercise.【单选题】

A.for

B.to

C.at

D.of

正确答案:B

答案解析:此题考查固定搭配。add?to意为“增加”，且符合上下文的意思。故B为正确答案。

A.more

B.less

C.high

D.highly

正确答案:D

答案解析:本句举了天花的例子，下一句指出很多孩子死于这些病，所以此处应为一个表严重的词。high是形容词，不能修饰后面的形容词。acute不是比较级，所以and后面也不应用比较级。
