单选题Text 2 They are said to be reluctant to forsake the pleasures of single life. But nothing could be further from the truth; British women are much more attached to marriage than their European counterparts, around 95.1 percent of British women have married at least once by age 49, the highest figure in the European Union. Only 91.2 percent of British men have walked up the aisle by the same age. Meanwhile, the much discussed trend for delaying marriage until later in life--blamed on career women reluctant to have children--may actually reflect a return to the historical norm. The average age of first marriage in Europe 200 years ago was 28, the same as British brides in 1998, according to a paper for the National Family and Parenting Institute, the independent thinktank set up by Jack Straw to advise on family issues. "The public conversation about marriage has often been conducted in an atmosphere fraught with anxiety that can easily tip over into what commentators have described as a moral panic," the report, comparing European trends in marriage, adds. "Changes in the marriage rate and in the way people form relationships are part and parcel of a society where change is rapid and individuals feel helpless in the face of new developments; yet it is vital that these issues can be discussed without blame." The paper does not include divorce rates. In 1997 Britain had the highest divorce rate in Europe, although by 1999 the rate had fallen to the level of the late 1980s. Despite much political consternation about the family, the report suggests British attitudes are more socially conservative than those of many EU counterparts. Nine out of 10 couples in Britain living with their children are married, compared to half in Finland. And while cohabiting is becoming the norm for European twentysomethings, "change has happened much more rapidly across the whole of the EU than in the UK", the report finds. Around a third of British under-thirties live with a partner, but it is closer to half in France and 40 per cent in Germany. "This report is about let's bring a cool head to this debate," said Gill Keep, head of policy at the institute. "It is much easier to take the panic out of the discussion if you look at it in a comparative way; things that you think are destroying your own society are actually common trends and they may not be that destructive." She said that despite anxiety over later marriages--the average age of first-time brides rose from 23 in the postwar period to 28 for women and 30 for men by 1999--historically this would have seemed normal. Social historian Christina Hardyment said that in the nineteenth century couples would not marry until they could afford to support a household. "Women below the middle classes would always work in some capacity, mainly in domestic service, and it made sense to save; people think of kings and queens and nobility being married off at 12 but that was highly unusual," she said.

单选题Working memory, or short-term memory, involves the ability to hold and use information in the immediate future. 21 is only held in working memory for about 20 seconds. The challenge that students 22 is to move information from their working memories into their long-term memories. If they don"t do this in about the first few minutes after receiving the information, that information can be lost. To keep this newly learned material from 23 away, it needs to enter the network of the brain"s wiring. After repeated practice, working memories are set down as permanent neuronal (神经的) circuits 24 to be activated (激活) when the information is needed. When a memory has been recalled 25 its neuronal circuits are more highly developed because of their repeated activation. 26 exercising a muscle, these circuits then become more efficient and easier to access and activate. Practice results 27 repeated stimulation of the memory circuit. Like hikers along a path 28 eventually leave a depression in the road, repeated practice stimulates cells in the memory circuit such that the circuit is reinforced and becomes 29 . This means it can be quickly turned from off to on, and switched 30 through a variety of cues coming in from the senses.

单选题{{B}}26-30{{/B}} While still in its early stages, welfare reform has already been judged a great success in many states, at least in getting people off welfare. It's estimated that more than 2 million people have left the rolls since 1994. In the past four years, welfare rolls in Athens County have been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $6 an hour. The result: The Athens County poverty rate still remains at more than 30 percent—twice the national average. For advocates (代言人) for the poor, that's an indication much more needs to be done. "More people are getting jobs, but it's not making their lives any better," says Kathy Lairn, a policy analyst at the Center on Budget and Policy Priorities in Washington. A center analysis of U.S. Census data nationwide found that between 1995 and 1996, a greater percentage of single, female-headed households were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin (毒素) that was poisoning the family," says Robert Rector, a welfare-reform policy analyst. "The reform is changing the moral climate in low-income communities. It's beginning to rebuild the work ethic (道德观), which is much more important." Mr. Rector and others argued that once "the habit of dependency is cracked", then the country can make other policy changes aimed at improving living standards.

单选题Is teaching important? Well. of course it is. There was a time when the necessary knowledge could be taught to the young by family members. But as societies became more complex and division of labor more common, it was impossible for family members to teach the information and skills young people needed to become useful members of the society. As the need for specialists appeared, the job of teaching came into being in our country, and teaching as a job has been of increasing importance over the past hundred years. Today, we have strict rules for teachers. We hope all children can attend schools. Many things tell us that teaching is indeed an "important" job. In recent years, there has been an increasing need for teachers to be "responsible". This means that the public expects teachers to succeed in teaching important information to the young. Teachers' salaries today, while not much, certainly are much higher than they were in past years. These increases have come about because people have realized that without enough salaries, people who have abilities will not become teachers. Today almost no one says that "anybody will do" for a teacher. The public expects "quality people" to teach the young, and progress is being made to give salaries that will make people who have abilities become teachers.

单选题{{B}}16-20{{/B}} President Coolidge's statement, "The business of America is business," still points to an important truth today-- that business institutions have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions possess this great prestige? One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected. Competition protects the freedom of the individual by ensuring that there is no monopoly (垄断) of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many businesses compete for the customers' dollar, they cannot afford to treat them like inferiors or slaves. A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, than democracy in preserving freedom. Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic (贵族的) idea of inherited privilege.

单选题We all know that it is possible for ordinary people to make their homes on the equator (赤道), although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)--we know that it is not only a dangerously cold place, but that people like you and me would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. Men had been traveling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time, have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, this is not true about landings in the polar region (which passenger aeroplanes do not make), but the weather, if we are flying at a height of 5000 meters above the Pole, is a delight. At 4 000 meters and More above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach. In the tropics (热带), on the other hand, you are not certain to keep clear of bad weather even at such heights as 18 000 or 20 000 meters. Aeroplanes can't climb as high or as quickly in cold air as in warm air. Nor can clouds. In practice, this is an advantage to the aeroplane, which is already at a good height when it reaches the polar region and so does not need to climb, while at the same time cold air keeps the clouds down low.

单选题It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits. The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far they are from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can't be answered, sooner or later, including even the matter of consciousness; to be sure, there may well be questions we can't think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.
