1、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital (婚外的) affairs will be even more common than now.But what are the reasons for this, and is the picture really so gloomy (明暗的)? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands－as they usually didn\'t have jobs outside the home. But with the rising number of women in well－paying jobs, this is no longer the case, So they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic (悲观的) as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Which of the following is true about the marriage in the United States today? ____【单选题】

A.Divorce leads to the breakup of the family.

B.More than half of the married couples get divorced.

C.American people marry more than four times.

D.More and more people are getting divorced.

正确答案:D

答案解析:本题有一定难度，干扰项干扰较大，B的干扰最大，但是原文提到的是almost 50% of marriages end in divorce now，所以B项里，more than half，夸大了原意，所以正确答案应该是D。

2、Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don\'t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack\'s electricity-generating feature could dramatically reduce the amount of a wearer\'s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.The backpack\'s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer\'s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack\'s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren\'t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!What is the most important feature of the backpack invented by Lawrence C. Rome and his colleagues?【单选题】

A.It produces electricity for electronic devices while the wearer walks.

B.It can be used as cell phones, GPS in the military actions or field studies.

C.It is small and convenient.

D.It is light and easy to carry.

正确答案:A

答案解析:第2段的第1句说，Lawrence C. Rome及其同事们发明的这种背包，当背着背包走路时，会有电能产生。该段最后一句告诉我们，背包的这种性能可减少背包的重量，因为不必携带备用电池。

3、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet and disease. Since 1957 a team of American researchers has monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential for the growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples.In the Western Electric study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.What does "malignancy" in the text refer to?【单选题】

A.Cancer.

B.Sickness.

C.Vitamins.

D.Disease.

正确答案:A

答案解析:这是一个很生僻的词，很少有考生认识，但是根据第1句话，“在众多的malignancy中，肺癌是最大的杀手”，这说明它是“癌症”。因此答案是A。

4、U. S. to Start $3. 2 Billion Child Health Study in JanuaryA study that will cost $3. 2 billion and last more than two decades to track the health of100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.Officials from the U. S. government\'s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.Officials said more than $200 million has been spent already and the study is projected to cost$3. 2 billion."We anticipate that in the long term , what we learn from the study will result in a significant savings in the nation\'s health care costs," Dr. Duane Alexander, who heads the NIH\'s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheid of the NIH, who heads the study.The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.It is expected that through the study the nation\'s health care costs____.【单选题】

A.Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 50% of the marriages continue to exist.

D.The statistics of divorce is not quite true.

正确答案:A

答案解析:从第3段里可以了解到离婚率并没有下降而是上升了，因此B选项不对。而C选项与第3段里“In fact，more than 50% of first marriages survive”所说不符，该选项没有提到是第一次婚姻。同样，D选项在文中也没有说到，文中第3段的最后一句只是说统计数据具有欺骗性，而没有说数据失实。
