单选题A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of" news from local crime to international politics, from sport to business to fashion to science, and the range of comment and special features (特写) as well, from editorial page to feature articles and interviews to criticism of books, art, theatre and music. A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interested in. What brings this variety together in one place is its topicality (时事性), its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient (短暂的) value. For all these reasons, no two people really read the same paper: what each person does is to put together out of the pages of that day"s paper, his own se- lection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.

单选题About four years ago, Kerry Sturgill found herself at a career crossroads: Should she stay in an industry populated by extroverts(外向型的人) or jump ship to a more reflective place where introverts like her were in the majority? Career counselors had told her to get out of the highly extroverted public relations fields " so you can be happy and do what you are. " Among the less fast-paced areas they pointed to: art, scientific research, data analysis. Such a move is definitely the right road for many introverts struggling to fit into an extroverted workplace. So, just what is an introvert anyway? It"s someone who is energized by thought and reflection, while extroverts are energized by socializing. Introverts naturally need to think before they speak. Extroverts use the speaking process to figure out what it is they want to say. And, needless to say, there are pluses and minuses to both personality types. Still, in the modern world where as many as two-thirds of the population may be extroverted, those who are the opposite can be misunderstood. They can be seen as antisocial, secretive, even territorial, because they can sometimes try to protect their "space" and quiet. Workplaces can actually benefit from having both types, says Deborah Barrett, program director of the Rice University MBA communications program. An introvert herself, she says she has the best of both worlds—working in an environment of professors, who tend towards introversion, yet getting to teach, which calls on her more "out there" skills. Here"s her advice for those looking to follow the same path: Make good use of e-mail. If you don"t get to make a point at a loud meeting, send a follow-up email sharing your thoughts. If you don"t have an office and are easily distracted by ongoing small talk, consider listening to music through headphones. But take care not to make your more sociable neighbors feel rejected. Sure, she says, if she had moved to a less stimulating environment, that might have " short- circuited a lot of nay pain , but I also believe it would have short-circuited learning what"s made me a much more well-rounded person." Her main lesson?" I don"t have to be an extrovert. I just have to play at being one for an hour. "

单选题An unidentified wit once said, "laugh, and the world laughs with you. Snore, and you sleep alone." Yet snoring is far from a laughing matter, as those unfortunates with good hearing, who are rightly subjected to the sounds of the snoring disorder, will testify. It has been estimated that one of eight Americans snores: this means that there are approximately 21 million people—women as well as men—who render an unpleasant sound when they are asleep. And assuming that each snorer disturbs the sleep of at least one other person, it necessarily follows that there are 21 million unhappy listeners. While a sleeping person breathes, either in or out, several structures in his nose and throat generate the snoring. The sounds, coming from the soft palate and other soft structures of the throat, are caused by vibratory responses to inflowing and outflowing air. When the soft tissues of the mouth and throat come close to the lining of the throat, the vibrations that occur are caused by the position of the tongue. In short, the noise made by snoring can be compared to the noise when breezes flutter a flag on a pole. The frequency of the vibrations depends on the size, density, and elasticity of the affected tissues and on the force of the air flow. Although it is usually the process of in haling or exhaling through the mouth that cause snoring, short snores come from the nose of an open-mouthed sleeper. In all fairness to snorers, however, it should be emphasized that snoring is an involuntary out which stops as the offender is awakened.

单选题Almost eight decades ago, the American educator Abraham Flexner published an article entitled The Usefulness of Useless Knowledge . In it, he argued that the most powerful intellectual and technological breakthroughs usually emerged from research that initially appeared "useless", without much relevance to real life. As a result, it was vital, Flexner said, that these "useless" efforts should be supported, even if they did not produce an immediate payback, because otherwise the next wave of innovation simply would not occur. "Curiosity, which may or may not produce something useful, is probably the outstanding characteristic of modem thinking," he declared. In 1929, Flexner persuaded a wealthy American family, the Bambergers, to use some of their donations to fund the Institute for Advanced Study (IAS) at Princeton to support exactly this kind of " undirected " research. And it paid off: brilliant Jewish scientists fleeing from Nazi Germany, such as Albert Einstein, gathered at the IAS to explore undirected ideas. And while some of these, such as Einstein"s own work developing his earlier theory of relativity, did not initially seem valuable, many eventually produced powerful applications (though after many decades). "Without Einstein"s theory, our GPS tracking devices would be inaccurate by about seven miles," writes Robbert Dijkgraaf, the current director of the IAS, in the foreword to a newly released reprint of Flexner"s article. Concepts such as quantum mechanics (量子力学) or superconductivity also seemed fairly useless at first—but yielded huge dividends at a later date. The reason why the IAS is re-releasing Flexner"s article now is that scientists such as Dijkgraaf fear this core principle is increasingly under threat. The Trump administration has released a projected budget that threatens to reduce funding for the arts, science and educational groups. Many Republicans believe that research is better financed by business or philanthropists (慈善家) than by government. But one striking fact about the past century is how much American innovation originated in federal projects; Silicon Valley would never have boomed were it not for the fact that state funding enabled the development of the World Wide Web, for example.

单选题This leaves us with the challenge of finding some politically practicable way to reduce greenhouse gas emissions. But it is an awkward truth that when most U.S. senators were asked informally in 2000 if they would support the Kyoto Protocol should President George W. Bush send it to the Senate for ratification, the overwhelming majority, Democrats as well as Republicans, said they could not. The reason for the liberals" surprising reply is clear. Many studies, not all by conservatives, suggest that full compliance with the terms of the Kyoto Protocol would likely lead to a deep American recession. For those willing to run this risk, sober reflection on the consequences of the economic collapse of 1929 and the subsequent worldwide depression with all its political and ultimately military consequences is certainly in order. That said, what can be done, in particular by our own country? Independent of the issues raised by the Kyoto Protocol, and given the weight of evidence that the problem of global warming is serious and fraught with dire consequences, failure to do anything at all and instead to promote "business as usual" is downright criminal. Yet the Bush administration has given no more than lip service to the problem, though that could be changing. It is one thing to weigh alternatives and implement compromises that reflect the complexity of the problem; it is quite another thing to do nothing, especially if doing nothing is just a way of securing support from certain industries that worsen the problem. There are, after all, things that can be done. Reopening a serious international dialogue, and not just saying a few good words, would be a useful if inadequate start. Not every problem must be solved before the weight of evidence becomes so compelling that certain initial steps become almost mandatory. We already know how to make more fuel-efficient automobiles, yet no national policy has surfaced to accomplish this. The scientific and engineering communities are the ones best suited to identify the scientific research that is still needed and the technical projects that show the greatest promise. These issues should be decided by them and not the politicians. Once solutions look promising, as a few already do, industry will be all too ready to jump in, for at that stage there is money to be made. And only a fool would underestimate human ingenuity when given a proper incentive, or the strength of American industry once the boiler is lit under it.

单选题It is not yet clear whether the deletion of data at the troubled bank was accidental or deliberate .

单选题Researchers analysed the diet of 16,000 people in 52 countries and identified three global eating patterns. The typical Western diet, high in fat, salt and meat, accounted for about 30% of heart attack risk in any population. A "prudent" diet high in fruit and vegetables lowered heart risk by a third. An Oriental diet, high in tofu, soy and other sauces, made no difference to heart attack risk. People who ate a Western diet had a 35% greater risk of having a heart attack than those who ate little or no fried. The typical Western diet has been widely linked to heart disease. High salt in the diet can raise blood pressure and the wrong type of fat can clog (阻塞) blood vessels. Ellen Mason, a cardiac nurse for the British Heart Foundation, said: "This study shows that it doesn"t matter whether you live in Bolton or Bombay, or whether you like to eat British, African Caribbean or Asian foods. The vital thing is to reduce your intake of salty, fried, fatty food to a minimum but increase the amount of fruit and vegetables you eat."

单选题Before Moko the dolphin turned up, the beached whales were in clear distress. But when Moko arrived at Mahia beach on the east coast of New Zealand"s North Island, their mood changed and they followed him to safety. The ability of some animals to communicate is well known. What"s less well documented, however, is the communication between species. Justin Gregg, vice president of the Dolphin Communication Project, said it is possible that a dolphin and a whale could communicate in some way. "But it wouldn"t be instructions like "Hey, buddy, the open ocean is over here. Follow me,"" he says. Dolphins use three forms of signaling to other dolphins—whistles, clicking and postures. A whale might have signals in common with a dolphin, just as different species of dolphins are known to share signals which might theoretically allow a form of basic inter-species communication. But just as it"s possible that Moko the dolphin and the stranded whales shared a signal, it is also possible that the whales just saw a vaguely similar creature and followed it. There are many reasons why different species communicate, says Vincent Janik, lecturer at the Sea Mammal Research Unit at St Andrew"s University. "The animals exploit the systems of others for their own benefits. Sometimes the benefits are the same for each, therefore they share information. Sometimes they are trying to take advantage of the other. Getting food may not be to the advantage of the one giving up the food."

单选题African American women"s search for societal acceptance often encompasses struggle between natural and socially constructed ideas of beauty. As an essential component in traditional African societies, cosmetic modification is ritualized to emphasize natural features of blackness. Defined by social occasion such as childhood development to maturity, indicators of marital status or the group to which you belong, beautification of the hair and body play an essential role. In our racially conscious society, presenting a physical image and being accepted is a complex negotiation between two different worlds. Hair is an outward expression of culture and heritage. It also represents a sense of personal style. In the search for the African American identity, blacks have undergone many different changes in hairstyle. Hairstyles are cultural classifiers of what African Americans consider beautiful. Hairstyles are a representation of the African American soul, all of their confidence and dignity show in how they present themselves on Sundays and on a daily basis. "During the sixties, white American youth used their hair to make a variety of political and philosophical statements," young blacks joined thereafter. The natural hairstyle not only was easier to care for, but also gave African Americans a closer tie to their heritage. Natural style serves as a visible imprimatur of blackness: a tribute to group unity: a statement of self-love and personal significance." By rejecting the white standards of beauty, black Americans halted the processes of using chemical straighteners or hot irons. A woman talks about her struggle. "I remember battling with the idea of going natural for several years. I never had the courage because every time I pictured myself with my natural hair, I never saw beauty. Now my hair is natural, thick and healthy." African American women are finding confidence within themselves to wear their hair naturally and feel beautiful about it. Many contemporary African Americans are avoiding high maintenance and feeling confident in their natural beauty. It was a different story in the past. African Americans were pressed. Shame was the motivation behind blacks losing their roots and ethnic identity. By being brainwashed into believing black people are "inferior" and white people are "superior" African Americans have mutilated and adjusted their bodies to try to look "pretty" by white standards. Hair is as different as the people it belongs to. People are finally recognizing that beauty is what helps to create our individual identities. Ultimately, individual confidence shapes and strengthens the culture of the African American community.

单选题It"s very interesting to note where the debate about diversity (多样化) is taking place. It is taking place primarily in political circles. Here at the College Fund, we have a lot of contact with top corporate (公司的) leaders; none of them is talking about getting rid of those instruments that produce diversity. In fact, they say that if their companies are to compete in the global village and in the global market place, diversity is an imperative. They also say that the need for talented, skilled Americans means we have to expand the pool of potential employees. And in looking at where birth rates are growing and at where the population is shifting, corporate America understands that expanding the pool means promoting policies that help provide skills to more minorities, more women and more immigrants. Corporate leaders know that if that doesn"t occur in our society, they will not have the engineers, the scientists, the lawyers, or the business managers they will need. Likewise, I don"t hear people in the academy saying "Let"s go backward. Let"s go back to the good old days, when we had a meritocracy (不拘一格选人才)” (which was never true—we never had a meritocracy, although we"ve come closer to it in the last 30 years). I recently visited a great little college in New York where the campus has doubled its minority population in the last six years. I talked with an African American who has been a professor there for a long time, and she remembers that when she first joined the community, there were fewer than a handful of minorities on campus. Now, all of us feel the university is better because of the diversity. So where we hear this debate is primarily in political circles and in the media—not in corporate board rooms or on college campuses.
