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 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 asleep; 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 ____ 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.difference

B.association

C.cooperation

D.agreement

正确答案:B

答案解析:从上下文判断，本句指的是depression和smoking之间的联系，不会是它们之间的差异(difference)、合作(cooperation)或一致性(agreement)。association的词义是“联系”，所以是答案。

2、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 ages 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 ____ 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.when

B.yet

C.however

D.while

正确答案:D

答案解析:整句话的意思是：从基因角度看，人都能活到85岁，但是虽然现在人们寿命确实比以前长了，仍然有一些疾病使得我们不能都活到那个岁数。所以此处应该填一个转折副词。

3、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 looking 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 ____. It might have to do with their genes. ｏｒsomething to do with ours.【单选题】

A.spouses

B.fans

C.partners

D.mates

正确答案:B

答案解析:spouse：配偶；fan：狂热仰慕者；partner：配偶；mate：伴侣。我们的世界知识告诉我们，任何人都不可能有数百万的配偶，所以只有fans是合适的选择。

4、When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction ａｎｄ　find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ ｏｒcell that causes the problem ａｎｄ　finds ways to effectively kill ｏｒcontain it. In the most serious of cases, in which the entire population of a region ｏｒcountry may be at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives ａｎｄ　ensure that the disease will not spread.The process of vaccination allows the patient\'s body to develop immunity to the virus ｏｒdisease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak ｏｒdead strain of the disease is actually injected into the patient in a controlled environment, so that his body\'s immune system can learn to fight the invader properly. Information on how to penetrate the disease\'s defenses is transmitted to all elements of the patient\'s immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped ａｎｄ　trained to deal with it, having already done so before.There are dangers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much fｏｒthe body to handle, resulting in the immune system succumbing, and, therefore, the patient\'s death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population ａｎｄ　killed massive numbers of settlers. Approximately l in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself ａｎｄ　dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3,000 Americans would be left dead.Fortunately, the smallpox virus was considered eradicated in the early 1970\'s, ending the mandatory vaccination of all babies in America. In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.The best title fｏｒthe text may be____.【单选题】

A.“Vaccinations: A Blessing ｏｒA Curse”

B.“Principles of Vaccinations”

C.“Vaccines: Methods ａｎｄ　Implications”

D.“A Miracle Cure Under Attack”

正确答案:C

答案解析:主旨题。选项C“疫苗：方法和内在含义”充分地概括说明了文章的主旨大意；而选项A、B、D均只涉及原文中的部分内容，以偏赅全，不能包含文章的全部内容。故正确答案为C。

5、She stood there, shaking with fury.【单选题】
