单选题According to the author, what will NOT happen if trial disappears in the United States? ( )

单选题Abortion. The word alone causes civil conversation to flee the room. This is largely because the prochoice and pro-life positions are being defined by their extremes, by those who scream accusations instead of arguments. More reasonable voices and concerns, on both sides of the fence, are given little attention. For example, pro-life extremists seem unwilling to draw distinctions between some abortions and others, such as those resulting from rape with an underage child. They would make no exception in the recent real-life case of a woman who discovered in her fifth month that her baby would be born dead due to severe disabilities. On the other hand, pro-choice extremists within feminism insist on holding inconsistent positions. The pregnant woman has an unquestionable right to abort, they claim. Yet if the biological father has no say whatsoever over the woman's choice, is it reasonable to impose legal obligations upon him for child support? Can absolute legal obligation adhere without some sort of corresponding legal rights? The only hope for progress in the abortion dialogue lies in the great excluded middle, in the voices of average people who see something wrong with a young girl forced to bear the baby of a rapist. Any commentary on abortion should include a statement of the writer's position. I represent what seems to b ea growing "middle ground" in pre-choice opinion. Legally, I believe in the right of every human being to medically control everything under his or her own skin. Many things people have a legal right to do, however, seem clearly wrong to me: adultery, lying to friends, walking past someone who is bleeding on the street. Some forms of abortion fall into that category. Morally speaking, my doubts have become so extreme that I could not undergo the procedure past the first three months and I would attempt to dissuade friends from doing so. Fanatics on both sides are using reprehensible and deceitful tactics. An honest dialogue on abortion must start by re-setting the stage, by denouncing the approaches that block communication.

单选题Sound moves from its source to the ear by wave like fluctuations in air pressure, something like the peaks and troughs or the lowest point of ocean waves. One way to keep from hearing sound is to use ear plugs. Another way is to cancel out the sound with anti-sound. Using a noise maker controlled by a microprocessor, engineers have produced sound waves that are half a wavelength out of phase with those of the noise to be quieted--each peak is matched to a trough, and vice versa. Once the researchers have recorded the offending sound, a microprocessor calculates the amplitude and wavelength of sound that will cancel out the highest and lowest points of the noise. It then produces an electric current that is amplified and fed to a loudspeaker, which produces anti-sound and wipes out the noise. If the anti-sound goes out of synchronization, a microphone picks up the leftover sound and sends it back to the microprocessor, which changes the phase of the anti-sound just enough to cause complete silence. The research team has concentrated on eliminating low-frequency noise from ship engines, which causes fatigue that can impair the efficiency and alertness of the crew, and may mask the warning sounds of alarm and fog signals.

单选题How did a peddler of cheap shirts and fishing rods become the mightiest corporation in America? The short version of Wal-Mart"s rise to glory goes something like this: in 1979 it racked up a billion dollars in sales; by 1993 it did that much business in a week; by 2001 it could do it in a day. It"s a shocking tale—one that propelled Wal-Mart from rural Arkansas, where it was founded in 1962, to the top of the Fortune 500. Sam Walton, Wal-Mart"s founder pushed sales growth continuously while squeezing costs with sophisticated information technology. He exhorted employees to sell better with the "ten-foot rule"(greet customers if they are that close). He was, in other words, an early evangelist for the first commandment of today"s economy: service rules. Wal-Mart, in fact, is the first service company to rise to the top of Fortune 500. When Fortune first published its list of the largest companies in America in 1995, Wal-Mart didn"t even exist. That year General Motors was America"s biggest company, and in every year that followed, either GM or another mighty industrial, Exxon, was No. 1. Wal-Mart"s achievement caps a bigger economic shift—from producing goods to providing services. Manufacturing"s share of U. S. employment peaked in 1953, at 35%. It has been declining steadily since. In the decade that will end in 2010, the Bureau of Labor Statistics figures that goods-producing industries will create 1. 3 million new jobs, compared to 20 million for service industries. To look at it another way, today there are about four times as many people working in service jobs as in other kinds of jobs. And even within manufacturing, services are an increasingly large share of operations. As America got richer, consumption got more complicated. With more income to throw around, people started spending more on services—movies and travel, mortgages to buy houses, insurance to protect those houses, the occasional weekends at a luxury hotel; Fortune calls this a shift in the demand pattern. Over the few years, only three of the ten fastest-growing occupations(software engineers, nurses, and computer support)pay middle-class salaries. The rest could be called Wal-Mart kinds of jobs—cashiers, retail assistants, food service, and so on. In short, the service economy is delivering more good jobs than ever before.

单选题 Education is one of the key words of our time. A man, without an education, many of us believe, is an unfortunate victim of adverse circumstances deprived of one of the greatest twentieth-century opportunities. Convinced of the importance of education, modern states "invest" in institutions of learning to get back "interest" in the form of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, is punctuated by textbooks--those purchasable wells of wisdom--what would civilization be like without its benefits? So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow citizens. If our educational system were fashioned after its bookless past we would have the most democratic form of "college" imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life. It is the ideal condition of the "equal start" which only our most progressive forms of modem education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no "illiterates"--if the term can be applied to people without a script--while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England 1876, and is still non-existent in a number of "civilized" nations. This shows how long it was before we deemed it necessary to make sure that 'all our children could share in the knowledge accumulated by the "happy few" during the past centuries. Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents, therefore the jungles and the grasslands know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children and no father is confronted with his inability to "buy" an education for his child.

单选题People need to be active to be healthy. Our modem lifestyle and all the conveniences we"ve become used to have made us sitting much of the time-and that"s dangerous for our health. Sitting around in front of the TV or the computer, riding in the car for even a short trip to the store and using elevators instead of stairs, all contribute to our inactivity. Physical inactivity is as dangerous to our health as smoking! Add up your activities during the day in periods of at least 10 minutes each. Start slowly ... and build up. If you"re already doing some light activities move up to more moderate ones. A little is good, but more is better if you want to achieve health benefits. Scientists say add up 60 minutes of physical activity every day to stay healthy or improve your health. Time needed depends on effort-as you progress to moderate activities, you can cut down to thirty minutes, four days a week. Physical activity doesn"t have to be very hard to improve your health. This goal can be reached by building physical activities into your daily routine. Just add up in periods of at least ten minutes each throughout the day. After three months of regular physical activity, you will notice a difference-people often say getting started is the hardest part. (From Handbook for Canada"s Physical Activity Guide to Healthy Active Living p.4. Canadian Society for Exercise Physiology, Ottawa, Ontario, 1998)
