1、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。

2、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.Researchers will collect all the following EXCEPT ____.【单选题】

A.genetic samples from people in the study.

B.biological samples from people in the study.

C.samples from the homes of the women and their babies.

D.samples of air and water from hospitals.

正确答案:D

答案解析:前3项在短文的第4段都有提及，第4项应该是“参加研究的妇女及其婴儿家中的空气与水等物质”，而不是“医院中的空气与水”。

3、LanguageWhen one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of language is a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Language a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different relationship of words in a sentence. Anglo-Saxon(old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections come into conflict with word order,. there may be trouble for the users of the language, as we shall see later when we turn our attention to such maters as WHO or WHOM and ME or l. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The eighteenth century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write.Which of the following can be best used as the title of the passage?【单选题】

A.The history of the English language.

B.Our changing attitude towards the English language.

C.Our changing language.

D.Some characteristics of modern English,

正确答案:C

答案解析:本文从各个方面谈及英语作为一种语言的发展变化，但并不是讲述英语的历史，所以选项A不对，选项C作为文章的题目最为贴切。选项B只是文章阐述的一个方面，不够全面。文章是在谈到英语的不断变化的时候谈到了现代英语的一些特点，所以选项D也过于片面。

4、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!Why is the outlook of marriage not as hopeless as it appears? ____【单选题】

A. Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 60% of the marriages continue to exist.

D.The statistics of divorce is reliable.

正确答案:A

答案解析:本题难度也不大，正确答案正好是选项A，所以看到A的信息提示，然后马上回到原文验证，可以找到答案依据是文章第三段第二句后半部分：…so marriage is still quite popular.
