1、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 ____ 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】

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 ____ 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 asleep; 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.effects

B.methods

C.steps

D.directions

正确答案:A

答案解析:句中的or是“即”，也就是说，to have self-medicating加上填入的词之后的意思相当于to improve mood。四个选项中只有选项A的effects（效果）是填入空格的最合适的词。to improve mood是自我治疗的效果。其他三个选项methods、steps、directions与self-medicating连用，意思分别为“自我治疗的方法”、“自我治疗的步骤”、“自我治疗的指导”，与句子的意思不相配。

3、ExerciseWhether or not exercise adds to the length of life, it is common experience that a certain ____ 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 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 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.heaviness

B.highness

C.amount

D.number

正确答案:C

答案解析:在四个选项中，A和B显然不符合逻辑，可供考虑的只有C和D。需要考虑的是，exercise这个词如果作为“体育锻炼”讲是不可数名词，只有作为“一项运动”讲时才是可数名词。根据上下文意思，exercise也不是用来强调体育项目的（没有用复数），而amount正好与不可数名词连用，number则须与可数名词连用，故C为正确答案。

4、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 ____ 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 doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.supportive

B.active

C.representative

D.protective

正确答案:C

答案解析:本题有一定难度，考查词义辨析。文章此处是说“在医诊室里得到一两个读数并不真正代表一天里的波动”，此处要用“代表”的意思，答案是C。
