单选题 At least since the Industrial Revolution, gender roles have been in a state of transition. As a result, cultural scripts about marriage have undergone change. One of the more obvious {{U}}(46) {{/U}} has occurred in the roles that women {{U}}(47) {{/U}}. Women have moved into the world of work and have become adept at meeting expectations in that arena, {{U}}(48) {{/U}} maintaining their family roles of nurturing and creating a(n) {{U}}(49) {{/U}} that is a haven for all family members. {{U}}(50) {{/U}} many women experience strain from trying to "do it all," they often enjoy the increased {{U}}(51) {{/U}} that can result from playing multiple roles. As women's roles have changed, changing expectations about men's roles have become more {{U}}(52) {{/U}}. Many men are relinquishing their major responsibility {{U}}(53) {{/U}} the family provider. Probably the most significant change in men's roles, however, is in the emotional {{U}}(54) {{/U}} of family life. Men are increasingly {{U}}(55) {{/U}} to meet the emotional needs of their families, {{U}}(56) {{/U}} their wives. In fact, expectations about the emotional domain of marriage have become more significant for marriage in general. Research on {{U}}(57) {{/U}} marriage has changed over recent decades points to the increasing importance of the emotional side of the relationships and the importance of sharing in the "emotion work" {{U}}(58) {{/U}} to nourish marriages and other family relationships. Men and women want to experience marriages that are interdependent,{{U}}(59) {{/U}} both partners nurture each other, attend and respond to each other, and encourage and promote each other. We are thus seeing marriages in which men's and women's roles are becoming increasingly more {{U}}(60) {{/U}}.

单选题For reasons yet to be fully understood, one out of ten human beings in the world is left-handed, and from one generation to the next, this ratio is roughly preserved. As we know, left-handedness cuts across socioeconomic, ethnic, and gender lines. Yet throughout history prominent figures in science—to say nothing of religion—have identified in left-handedness signs of viciousness or worse. In 1903, Italian physician Cesare Lombroso identified left-handedness as one of the degeneracy signs of the born criminals. Three years later, Dr. Wilhelm Fliess suggested that left-handedness was a reliable identification of homosexuality. And in 1937 British psychologist Cyril Burt declared left-handedness to be a mark of an ill-organized nervous system. As demonstrated by all the "therapeutic" coercion that left-handed children were subjected to during the first half of the 20th century, these biases had more than just a theoretical impact. Yet even when this gauche predilection was being discouraged, handism was certainly never taken as seriously as racism or sexism now is. Perhaps it's the arbitrary nature of the trait that has militated against meaningful discrimination. After all, even when both parents are right-handed, there is still a 10 percent Chance that they will bring a left-handed baby into the world. Moreover, a white baby born in Scarsdale is just as likely to be left-handed as a black baby in Harlem. Hence when the left-handed George Bush became President of the United States, it was hardly interpreted as a blow against prejudice. Nor was much attention paid to the fact that Ronald Reagan and Gerald Ford were also southpaws.

单选题Passage 4 The United States is a country made up of many different races. Usually they are mixed together and can't be told from one another. But many of them still talk about where their ancestors came from. It is something they are proud of. The original Americans, of course were the Indians. The so-called white men who then came were mostly from England. But many came from other countries like Germany and France. One problem the United States has always had is discrimination. As new groups came to the United States they found they were discriminated against. First it was the Irish and Italians. Later it was the blacks. Almost every group has been able to finally escape this discrimination. The only immigrants who have not are the blacks. Surprisingly enough the worst discrimination today is shown towards the Indians. One reason the Indians are discriminated against is that they have tried so hard to keep their identity. Of course they are not the only ones who have done so. The Japanese have their Little Tokyo in Los Angeles and the Chinese a Chinatown in New York. The Dutch settlement in Pennsylvania also stays separate from other people. Their towns are like something from the 19th century. They have a different reason from the other groups for staying separately. They live separately for religious reasons rather than keep together in a racial group. Although some groups have kept themselves separate and others have been discriminated against, all groups have helped make the United States a great county. There is no group that has not helped in some way. And there is no group that can say they have done the most to make it a great country. Many people still come from other countries to help the United States grow. A good example is the American project that let a man walk on the moon. It was a scientist from Germany who was most responsible for doing that. It is certain that in the future the United States will still need the help of people from all racial groups to remain a great country.

单选题It is often claimed that nuclear energy is something we cannot do without. We live in a consumer society where there is an enormous demand for commercial products of all kinds. Moreover, an increase in industrial production is considered to be one solution to the problem of mass unemployment. Such an increase presumes an abundant and cheap energy supply. Many people believe that nuclear energy provides an inexhaustible and economical source of power and that it is therefore essential for an industrially developing society. There are a number of other advantages in the use of nuclear energy. Firstly, nuclear power, except for accidents, is clean. A further advantage is that a nuclear power station can be run and maintained by relatively few technical and administrative staff. The nuclear reactor represents an enormous step in our scientific evolution and, whatever the antinuclear group says, it is wrong to expect a return to more primitive sources of fuel. However, opponents of nuclear energy point out that nuclear power stations bring a direct threat not only to the environment but also to civil liberties. Furthermore, it is questionable whether ultimately nuclear power is a cheap source of energy. There have, for example, been very costly accidents in America, in Britain and, of course, in Russia. The possibility of increases in the cost of uranium (铀) in addition to the cost of greater safety provisions could price nuclear power out of the market. In the long run, environmentalists argue nuclear energy wastes valuable resources and disturbs the ecology to an extent which could bring about the destruction of the human race. Thus, if we wish to survive, we cannot afford nuclear energy. In spite of the case against unclear energy outlined above, nuclear energy programmes are expanding. Such an expansion assumes a continual growth in industrial production and consumer demands. However, it is doubtful whether this growth will or can continue. Having weighed up the arguments on both sides, it seems there are good economic and ecological reasons for sources of energy other than nuclear power.

单选题"Popular art" has a number of meanings, impossible to define with any precision, which range from folklore to junk. The poles are clear enough, but the middle tends to blur. The Hollywood Western of the 1930" s, for example, has elements of folklore", but is closer to junk than to high art or folk art. There can be great trash, just as there is bad high art. The musicals of George Gershwin are great popular art, never aspiring to high art. Schubert and Brahms, however, used elements of popular music—folk themes—in works clearly intended as high art. The case of Verdi is a different one: he took a popular genre—bourgeois melodrama set to music ( an accurate definition of nineteenth-century opera)—and, without altering its fundamental nature, transmuted it into high art. This remains one of the greatest achievements in music, and one that cannot be fully appreciated without recognizing the essential trashiness of the genre. As an example of such a transmutation, consider what Verdi made of the typical political elements of nineteenth-century opera. Generally in the plots of these operas, a hero or heroine—usually portrayed only as an individual, unfettered by class—is caught between the immoral corruption of the aristocracy and the doctrinaire rigidity or secret greed of the leaders of the proletariat. Verdi transforms this naive and unlikely formulation with music of extraordinary energy and rhythmic vitality , music more subtle than it seems at first hearing. There are scenes and arias that still sound like calls to arms and were clearly understood as such when they were first performed. Such pieces lend an immediacy to the otherwise veiled political message of these operas and call up feelings beyond those of the opera itself. Or consider Verdi"s treatment of character. Before Verdi, there were rarely any characters at all in musical drama, only a series of situations which allowed the singers to express a series of emotional states. Any attempt to find coherent psychological portrayal in these operas is misplaced ingenuity. The only coherence was the singer"s vocal technique: when the cast changed, new arias were almost always substituted, generally adapted from other operas. Verdi"s characters, on the other hand, have genuine consistency and integrity, even if, in many cases, the consistency is that of pasteboard melodrama. The integrity of the character is achieved through the music: once he had become established, Verdi did not rewrite his music for different singers or countenance alterations or substitutions of somebody else"s arias in one of his operas, as every eighteenth-century composer had done. When he revised an opera, it was only for dramatic economy and effectiveness.

单选题Hello back there! This is me, in the future. It's great here. We finally have robots that do things for us, although none of them are very attractive, at least not after the third or fourth date. Dogs and cats developed the power of speech several years ago, and turn out to have very little interesting to say beyond requests for food and, on the part of cats, expressions of condescension. One thing that has not changed in the 50 years since you guys were merging and purging all over the place is our reliance on media. Today we have 484, 567, 543 channels of great programming, which correspond exactly to the population of the U. S. It's really fabulous. Each of us has his or her own mix that completely serves our interests and virtual habits. I say virtual habits because none of us have any real habits to speak of, good or bad. They were outlawed in 2025, and most of us agree that we're happier without any. Our programming mixtures reach us through a variety of pipelines all owned by one of four Great Big Media Companies. These are all exactly alike in their collection of assets, each of them owning broadcast, narrowcast, die-cast, retrocast and cybercast, broadband, narrowband, audio, video, satellite and an upload-and-download phalanx of option-driven interfaces. Each of our Great Big Media Companies has thousands of brands that make us feel all warm and toasty and provide an emotional connection to a past that nobody can actually remember. We love our GBMCs and buy their stocks all the time. And they're getting bigger. Not long ago, the largest GBMC declared itself to be a nation, established a virtual army and invaded Nova Scotia. Right now, it's fighting the Canadians, who are holding out for preferred stock in the new entity before they capitulate. So things have changed a lot, except maybe for one thing. As I'm dictating this into the cyber-neural-net, I am sitting on a soft object with a rather high back, which is necessary as, like all other human beings now, I have no real bone structure. That's right, it's my beloved couch! I sit on my couch all day long. I do business from my couch, since everything is now conducted online. I am served my meals on my couch. My family members catch up with one another's virtual day while sitting on our couch. The only time we leave our couch is when we are conveyed upstairs to bed, which is just another couch. So from our couch to yours, hello! That's your future! See you there!

单选题The high income tax is harmful ______ it may discourage people from trying to earn more.

单选题If women are mercilessly exploited (剥削) year after year, they are only themselves to blame. Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put aside because of the change of fashion. When you come to think of it, only a woman is capable of standing in front of a wardrobe (衣柜) packed full of clothes and announcing sadly that she has nothing to wear. Changing fashions are nothing more than the intentional creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. Skirts are lengthened or shortened; necklines are lowered or raised, and so on. No one can claim that the fashion industry contributes anything really important to society. Fashion desihners are rarely concerned with vital things like warmth, comfort and durability (耐用). They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look fight. There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, delicately picking her way through deep snow in high-heeled shoes. When comparing men and women in the matter of fashion the conclusions to be drawn are obvious. Do the constantly changing fashion of women's clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be treated by fashion designers. Do their unchanging styles of dress reflect basic qualifies of stabililty and feasibility? That's for you to decide.
