单选题Most people who travel long distances complain of jetlag (飞行时差反应). Jetlag makes business travelers less productive and more prone 21 making mistakes. It is actually caused by 22 of your "body clock"—a small cluster of brain cells that controls the timing of biological 23 . The body clock is designed for a 24 rhythm of daylight and darkness, so that it is thrown out of balance when it 25 daylight and darkness at the wrong times in a new time zone. The 26 of jetlag often persist for days 27 the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is 28 that is based on proven 29 pioneering scientific research. Dr. Martin Moore-Ede has 30 a practical strategy to adjust the body clock much sooner to the new time zone 31 controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates 32 of the discomfort of jetlag. A successful time zone shift depends on knowing the exact time to either 33 or avoid bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule 34 light exposure depends a great deal on 35 travel plans. Data on a specific flight itinerary (旅行路线) and the individual"s sleep 36 are used to produce a Trip Guide with 37 on exactly when to be exposed to bright light. When the Trip Guide calls 38 bright light, you should spend time outdoors if possible. If it is dark outside, or the weather is bad, 39 you are on an aeroplane, you can use a special light device to provide the necessary light 40 for a range of activities such as reading, watching TV or working.

单选题 The average population density of the world is 47 persons per square mile. Continental densities range from no permanent inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per square mile in Iceland to 831 per square mile in the Netherlands. Within countries there are wide variations of population densities. For example, in Egypt, the average is 55 persons per square mile, but 1,300 persons inhabit each square mile in settled portions where the land is arable. High population densities generally occur in regions of developed industrialization, such as the Netherlands, Belgium, and Great Britain, or where lands are intensively used for agriculture, as in Puerto Rico and Java. Low average population densities are characteristic of most underdeveloped countries. Low density of population is generally associated with a relatively low percentage of cultivated land. This generally results from poor-quality lands. It may also be due to natural obstacles to cultivation, such as deserts, mountains or malaria-infested jungles, to land uses other than cultivation, as pasture and forested land, to primitive methods that limit cultivation, to social obstacles, and to land ownership systems which keep land out of production. More economically advanced countries of low population density have, as a rule, large proportions of their populations living in urban areas. Their rural population densities are usually very low. Poorer developed countries of correspondingly low general population density, on the other hand, often have a concentration of rural population living on arable land, which is as great as the rural concentration found in the most densely populated industrial countries.

单选题These days we hear a lot of nonsense about the "great classless society". The ideal that the twentieth century is the age of the common man has become one of the great cliches of our time. The same old arguments are put forward in evidence. Here are some of them: monarchy as a system of government has been completely discredited. The monarchies that survive have been deprived of all political power. Inherited wealth has been savagely reduced by taxation and, in time, the great fortunes will disappear altogether. In a number of countries the victory has been complete. The people rule; the great millennium has become a political reality. But has it? Close examination doesn't bear out the claim. It is a fallacy to suppose that all men are equal and that society will be leveled out if you provide everybody with the same educational opportunities. (It is debatable whether you can ever provide everyone with the same educational opportunities, but that is another question.) The/'act is that nature dispenses brains and ability with a total disregard for the principle of equality. The old rules of the jungle, "survival of the fittest", and "might is right" are still with us. The spread of education has destroyed the old class system and created a new one. Rewards are based on merit. For "aristocracy" read "meritocracy"; in other respects, society remains unaltered: the class system is rigidly maintained. Genuine ability, animal cunning, skill, the knack of seizing opportunities, all bring material rewards. And what is the first thing people do when they become rich? They use their wealth to secure the best possible opportunities for their children, to give them a good start in life. For all the lip service we pay to the idea of equality, we do not consider this wrong in the western world. Private schools which offer affair advantages over state schools are not banned because one of the principles in a democracy is that people should be free to choose how they will educate their children. In this way, the new meritocracy can perpetuate itself to a certain extent: an able child from a wealthy home can succeed far more rapidly than his poorer counterpart. Wealth is also used indiscriminately to further political ends. It would be almost impossible to become the leader of a democracy without massive financial backing. Money is as powerful a weapon as ever it was. In societies wholly dedicated to the principle of social equality, privileged private education is forbidden. But even here people are rewarded according to their abilities. In fact, so great is the need for skilled workers that the least able may be neglected. Bright children are carefully and expensively trained to become future rulers. In the end, all political ideologies boil down to the same thing: class divisions persist whether you are ruled by a feudal king or an educated peasant.

单选题The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment (承担的义务), self-improvement. Ask a bachelor (单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children, But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money; buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

单选题She was slim and he liked her that way. So he called a lawyer. The result was a contract. According to the document, the fresh-faced bride agreed to pay a fine for each pound she gained in weight, the money refundable upon its loss. The paper signed, and the wedding went on. This is a prenuptial agreement—one more indication of the strange pass of marriage in this most trans- actional decade. You are welcome to marriage, contractual style, where increasingly detailed le- gal documents spell out everything from who' s going to do the dishes to who' s going to get the house when you split. This is family planning taken to extreme. Once employed solely by the rich, second-timers and the old industrialist carrying off the latest young cookie, the prenuptial agreement—a written pact between a couple outlining the financial obligation in the event of divorce—is becoming com- monplace in a litigious, disillusioned and materialistic age in which one in every two marriages is projected to end in divorce. The only question is: What about love? When asked whether anyone believes in Cupid any- more, Dr. Michael Vincent Miller says, "Given a century that is full of sexual liberation, com- purer-dating services and so on, one feels tempted to reply, Only in a mood of desperate nostalgia. '""Prenups do assume negativity. Founded on disillusionment, they cannot be separated from the United States." The result, argues Miller, is a kind of defending mentality. "We have got good at managing finiteness, failure and trouble with a sort of 'What's yours and what's mine is mine's realism. We've seen it isn't all about love. We've seen there's power politics in there—a fight for control, and when you've got those things, you're half way to lawyers and money." In other ways, however, the compacts embody positive, even idealistic thinking about marriage, love and relations, a law scholar Isabel Marcus believes. Marcus says, "Contracts could spell the end of romantic love as salvation. They say love exists, but that it's best accompanied by good, hard thinking about equitability." By writing a contract, the couple gains control of its marriage. "What' s good is it contributes to honesty; what' s unfortunate is the idea that any contract can govern your emotions," says the author of the book The Nature of Love.
