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 case 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 ____ useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.will?be

B.would?be

C.is

D.are

正确答案:C

答案解析:本句是个条件句。从句中动词一般用现在时表示“未来”。这就排除了will?be和would?be。virus是单数，因此D也不正确。故C为正确答案。

2、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto ａｎｄ　the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects ｏｒto improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were ｓｅｌｅｃｔed to provide a mix of French ａｎｄ　English participants, urban ａｎｄ　rural schools, ａｎｄ　schools located in high, moderate ａｎｄ　low socioeconomic neighborhoods. Participants were divided into three groups: never smokers； smokers who did not use cigarettes to self-medicate, improve mood ｏｒphysical state； smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep ｏｒstaying ____； felt unhappy, sad, ｏｒdepressed； felt hopeless about the future； felt vexed, antsy ｏｒtense； ａｎｄ　worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professｏｒat the University of Montreal Department of Social ａｎｄ　Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression ａｎｄ　smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

A.asleep

B.awake

C.still

D.silent

正确答案:A

答案解析:第九题选了trouble，空格所在的句子是“. . . had trouble going to sleep ｏｒstaying”。or是“即”的意思，也就是说had trouble going to sleep意思上就相当于staying up根据这一判断，填入空格的词非awake莫属。

3、ExerciseWhether ｏｒnot exercise adds to 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 ____ throughout life. Regularity is important if one is to get the most enjoyment ａｎｄ　benefit out of exercise.【单选题】

A.with

B.from

C.in

D.on

正确答案:C

答案解析:四个选项中只有in可与participate连用，意为“参加”，in的宾语是引导定语从句的关系代词that。

4、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people ｏｒsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit fｏｒsingles ｏｒunhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study authｏｒJulianne Holt Lunstad, a psychologist who specializes in relationships ａｎｄ　health, said in a prepared statement.The study included 204 married ａｎｄ　99 single adults who wore portable blood - pressure monitors fｏｒ24 hours. The monitors recorded blood pressure at random intervals ａｎｄ　provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally ____ in everyday life. Getting one ｏｒtwo readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married ａｎｄ　single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet ａｎｄ　having regular doctｏｒvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.take

B.do

C.make

D.want

正确答案:B

答案解析:本题难度不大，考查词义辨析。文章此处是说“……不管测试者每天都做什么”，很明显，要用动词do，答案是B。

A.reducers

B.improvers

C.creators

D.removers

正确答案:B

答案解析:第一段和第二段都说到，抽烟缓解抑郁心情最终导致更抑郁。本句Smokers who used cigarettes as mood had higher risks of elevated depressive symptoms than teens who had never smoked. 表达的是同样的意思。文章第二段和第三段都出现improve mood，所以，mood后面要填入的词应该是improvers选项A、C、D的意义均不符合上下文。
