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.

单选题{{B}}Passage Three{{/B}} Through the years, our view of what leadership is and who can exercise it has changed considerably. Leadership competencies have remained constant, but our understanding of what it is, how it works, and the ways in which people learn to apply it has shifted. We do have the beginnings of a general theory of leadership, from history and social research and above all from the thoughts of reflective practitioners such as Moses, Julius Caesar, and James Madison, and in our own time from such disparate sources of wisdom as Gandhi, Winston Churchill, Mao Tse-tung, and Henry Kissinger, who have very little in common except that they have not only been there but tried with some fairness to speculate on paper about it. But tales and reflective observation are not enough except to convince us that leaders are physically strong and abnormally hard workers. Today we are a little closer to understanding how and who people lead, but it wasn't easy getting there. Decades of academic analysis have given us more than 350 definitions of leadership. Literally thousands of empirical investigations of leaders have been conducted in the last seventy-five years alone, but no clear understanding exists as to what distinguishes leaders from non-leaders, and perhaps more important, what distinguishes effective leaders from ineffective leaders and effective organizations from ineffective organizations. Never have so many labored so long to say so little. Multiple interpretations of leadership exist, each providing a fragment of insight but each remaining an incomplete and wholly inadequate explanation. Most of these definitions don't agree with each other, and many of them would seem quite remote to the leaders whose skills are being examined. Definitions reflect fashions, political tides and academic trends. They don't always reflect reality and sometimes they just represent nonsense. It's as if what Braque once said about art is also true of leadership: "The only thing that matters in art is the part that cannot be explained. " Many theories of leadership have come and gone. Some looked at the leader. Some looked at the situation. None has stood the test of time. With such a track record, it is understandable why leadership research and theory have been so frustrating as to deserve the label "{{U}}the La Brea Tar Pits{{/U}}" of organizational inquiry.
