1、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 or to 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 or physical 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 or staying ____; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; 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 professor at 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 or staying”。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。

2、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, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there\'s a good reason to ____ 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 is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.keep

B.put

C.destroy

D.eradicate

正确答案:A

答案解析:keep?the?virus:保存病毒。put?the?virus是不正确的表达，后面必须有地点状语。如：You?can?put?the?virus?in?a?bottle．??destroy?the?virus和eradicate?the?virus都是“消灭病毒”的意思，跟后半句话在意思上是矛盾的。故A为正确答案。

3、ExerciseWhether or not 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. For them moderation is ____ 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 for one person of forty but folly for another. The safe limit for exercise 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 for anyone. 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 limit themselves 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.against

B.below

C.on

D.of

正确答案:D

答案解析:本句中is后面应该是表语部分，四个选项中只有of合适，of?importance＝important,??of?vital?importance＝very?important。

4、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 or minimize 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 ____ 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 for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something 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 for the 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 or faithful 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 for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.【单选题】

B.hands

C.arms

D.faces

正确答案:D

答案解析:body:躯体；hand:手；arm:手臂；face:脸。由于调查对象看的是男士的头部，因此选face是对的。

5、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily 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 author Julianne 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 for 24 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 do in everyday life. Getting one or two 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 ____ 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 doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】
