单选题 Academic Mobility Scholars and students have always been great travelers. "Academic mobility" is now often stated as a fundamental necessity for economic and social progress in the world, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold. Mobility of this kind means also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have an interest in being credited with a startling discovery, or a new technique. It must also have been reassured to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect. In the twentieth century, and particularly in the last twenty years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aero plane, making contact between scholars even in most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centers of learning, and a far greater number of scholars and students. In addition, one must recognize the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests ale precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.

单选题下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。 Paper or Plastic? Take a walk along the Chesapeake Bay, and you are likely to see plastic bags floating in the water. Ever since these now ubiquitous (到处存在的) symbols of American super-consumption showed up in the supermarkets, plastic shopping bags have made their {{U}}(51) {{/U}} into local waterways, and from there, into the bay, where they can {{U}}(52) {{/U}} wildlife. Piles of them - the {{U}}(53) {{/U}} takes centuries to decompose (分解) -- show up in landfills and on city streets. Plastic bags also take an environmental toll in the form of millions of barrels of oil expended every year to produce them. Enter Annapolis {{U}}(54) {{/U}} you will see plastic bags distributed free in department stores and supermarkets. Alderman Sam Shropshire has introduced a well-meaning proposal to ban retailers (零售商) {{U}} (55) {{/U}} distributing plastic shopping bags in Maryland's capital. Instead, retailers would be required to offer bags {{U}}(56) {{/U}} recycled paper and to sell reusable bags. The city of Baltimore is considering a similar measure. Opponents of the idea, however, argue that {{U}}(57) {{/U}} bags are harmful, too: they cost more to make, they consume more {{U}}(58) {{/U}} to transport, and recycling them causes more pollution than recycling plastic. The argument for depriving Annapolis residents (居民) of their plastic bags is {{U}}(59) {{/U}} accepted. Everyone in this {{U}}(60) {{/U}} is right about one thing: disposable shopping bags of any type are {{U}}(61) {{/U}}, and the best outcome would be for customers to reuse bags instead. Annapolis's mayor is investigating how to hand out free, reusable (可以再度使用的) shopping bags to city residents, a proposal that can proceed regardless of whether other bags are banned. A less-expensive {{U}}(62) {{/U}} would be to encourage retailers to give discounts to customers {{U}}(63) {{/U}} bring their own, reusable bags, a policy that a spokesman for the supermarket Giant Food says its chain already has in place. And this policy would be more {{U}} (64) {{/U}} if stores imitated furniture mega-retailer Ikea and charged for disposable bags at the checkout counter. A broad ban on the use of plastic shopping bags, which would merely replace some forms of pollution with others, is not the {{U}}(65) {{/U}}.

单选题Mobile Phones: Change Our Life In the case of mobile phones, change is everything. Recent research indicates that the mobile phone is changing not only our culture, but our very bodies as well. First, let"s talk about culture. The difference between the mobile phone and its parent—the fixed-line phone, is that a mobile phone corresponds to a person, while a landline goes to a place. If you call my mobile, you get me. If you call my fixed-line phone, you get whoever answers it. This has several implications (含义). The most common one, however, and perhaps the thing that has changed our culture forever, is the "meeting" influence. People no longer need to make firm plans about when and where to meet. Twenty years ago, a Friday night would need to be arranged in advance. You needed enough time to allow everyone to get from their place of work to the first meeting place. Now, however, a night out can be arranged on the run. It is no longer "see you there at 8", but "text me around 8 and we"ll see where we all are". Texting changes people as well. In their paper, "Insights into the Social and Psychological Effects of SMS (Short Message Service) Text Messaging", two British researchers distinguished between two types of mobile phone users: the "talkers" and the "texters"—those who prefer voice to text messages and those who prefer text messages to voice. They found that the mobile phone"s individuality and privacy gave texters the ability to express a whole new outer personality. Texters were likely to report that their family would be surprised if they were to read their texts. This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well. Another scientist wrote of the changes that mobiles have brought to body language. There are two kinds that people use while speaking on the phone. There is the "speakeasy": the head is held high, in a self-confident way, chatting away. And there is the "spacemaker": these people focus on themselves and keep out other people. Who can blame them? Phone meetings get cancelled or reformed and camera-phones intrude (侵入) on people"s privacy. So, it is understandable if your mobile makes you nervous. But perhaps you needn"t worry so much. After all, it is good to talk.

单选题Now, however, armed with brain-scanning tools and a sophisticated understanding of biochemistry, researchers are realizing that the mental effects of exercise are far more profound and complex than they once thought. The process starts in the muscles. Every time a bicep (二头肌) or quad contracts and releases, it sends out chemicals, including a protein called IGF-1 that travels through the bloodstream, across the blood-brain barrier and into the brain itself. There, IGF-1 takes on the role of foreman(工头, 领班)in the body's neurotransmitter factory. It issues orders to ramp up production of several chemicals, including one called brain-derived neurotrophic factor, or BDNF. Ratey, author of the upcoming book "Spark: The Revolutionary New Science of Exercise and the Brain." calls this molecule" Miracle-Gro for the brain. "It fuels almost all the activities that lead to higher thought. The process of exercise functioning on mind startsA. in the muscles.B. in the bloodstreams.C. in the brain.D. in the heart.

单选题Perfect Crime Taiwan police cannot decide whether to treat it as an extremely clever act of stealing or an even cleverer cheat (诈骗). Either way, it could be the perfect crime (犯罪), because the criminals are birds—homing pigeons! The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up then. The ear owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off. There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home ear thief, however, may in fact be the work of an even lazier and more inventive criminal mind—one that avoids (避免) not only collecting money but going out to steal the car in the first place. Police officer Chen says that the criminal probably has played a double trick, he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an ad (启事) in the newspaper asking for help. The theory is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded—under 3,000 Taiwanese dollars—seems too little for a car worth many times more. Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. "We have more important things to do," he said.

单选题The absence of Y2K induced problems has been remarkable. There were no falling planes, no exploding power stations, no rogue missiles. Those horrors were always the stuff of myth. But so sparse were tales of disaster that journalists were driven to reporting on malfunctions in the breath-testing' machines used on drunken motorists by the Hong Kong police. More problems may emerge in the coming weeks. Overall, though, Y2K has turned out to be Y20K: One partial explanation is that the huge effort lavished(浪费) on bug-squashing has worked. The United States, according to a Commerce Department estimate, spent about 100 billion on the problem; the rest of the world probably spent about the same again. Those numbers are far smaller than some of the more exotic figures trailed a few years ago, but they are still substantial. Yet even the countries that had begun work late and done little-southern Europe, Russia, much of Asia-had a trouble free new year. So was the money wasted? According to the author, the amount of money spent on the Y2K problem wasA. too much.B. not enough.C. significant.D. the same as had been expecte

单选题 下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。请根据文章的内容，从每题所给的4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} Pushbike Danger{{/B}} Low speed bicycle crashes can badly injure -- or even kill -- children if they fall onto the ends of the handlebars (车把). So a team of engineers is redesigning it to make it safer. Kristy Arbogast, a bioengineer at the Children's Hospital of Philadelphia in Pennsylvania, began the project with her colleagues. The cases they reviewed about serious abdominal (腹部的) injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents, "The task was to identify how the injuries occurred and come up with some countermeasures," she says. By interviewing the children and their parents, Arbogast and her team were able to reconstruct many of the accidents and identified a common cause for serious injuries. They discovered that most cases occur when children hit an obstacle at slow speed, causing them to topple (摇摆) over. To maintain their balance the children turn the handlebars through 90 degrees -- but their momentum (冲力) forces them into the end of the handlebars. The bike then falls over and the other end of the handlebars hits the ground, pushing it into their abdomen (腹部). The solution the group came up with is a handgrip (握柄) fitted with a spring and damping (减速) system. The spring absorbs up to 50 per cent of the forces transmitted (传递) through the handlebars in an impact. The group hopes to commercialize the device, which should add only a few dollars to the cost of a bike. "But our task has been one of education because up until now, bicycle manufacturers were unaware of the problem," says Arbogast.

单选题The Development of Personality Personality is to large extent inherent. A-type parents usually bring A-type offspring. But the environment must also have a profound effect, since if competition is important to the parents, it is likely to become a major factor in the lives of their children. One place where children soak up (浸泡) A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A-types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences: Remember that Philippines, the first marathon runner, dropped dead seconds after saying, "Rejoice, We conquer!" By far the worst form of competition in schools is the disproportionate emphasis on examinations. It is a rare school that allows pupils to concentrate on those things they do well. The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful. Obviously, it is neither practical nor desirable that all A youngsters change into B"s. The world needs types, and schools have an important duty to try to fit a child"s personality to hide possible future employment. It is top management. If the preoccupation of schools with academic work was lessened, more time might be spent teaching children surer values. Perhaps selection for the caring professions, especially medicine, could be made less by good grades in chemistry and more by such considerations as sensitivity and sympathy. It is surely a mistake to choose our doctors exclusively form A-type stock. B"s are important and should be encouraged.
