单选题{{B}}Passage One{{/B}} Following the disaster at Chernobyl, nuclear experts proposed a program to make nuclear power around the world safer. At the top of the agenda were fundamental improvements in the training of operators and the design of control systems for reactors. The International Atomic Energy Agency also chose the meeting on the Chernobyl accident to announce it would step up its safety checks of nuclear power stations. Up to that time, with more than 300 nuclear power plants operating worldwide, the IAEA had sent safety review teams to inspect stations in only nine countries, mostly in the Third World. Now the emphasis would switch to reactors in the developed world, including the Soviet Union, US and Britain. According to regulations, an international safety review could be undertaken by the IAEA only following a formal request from a member country. However, the meeting in Vienna produced a list of 14 recommendations for future action following the Soviet report on Chernobyl. The IAEA meeting said that better fire protection and more advanced techniques for firefighting were needed. The possibility of developing lightweight clothing to protect firefighters from radiation was of particular interest; so was the use of robot firefighters. The Soviet Union used minerals and sand to damp down the fires. Both Soviet and Western experts agreed there was no way of knowing in advance if this would work. Luckily, it did. Decontamination (去除放射性污染) was another area where the international nuclear community was anxious to learn more from Chernohyl. The Soviet clean-up involved treating buildings and the ground around the reactor with special chemicals to reduce the spread of radioactive dust. Heavily contaminated soil was removed. At the final press conference about the Chemohyl accident, the leader of the Soviet delegation (代表团) claimed that Chernobyl would not be repeated. There would have to be greater efforts to make sure that the design of nuclear plants eliminated the possibility of errors by operatorns. This would include making it difficult to override (使无效) safety systems, as happened at Chernobyl. It would also mean greater use of simulators (模拟装置) to train operators.

单选题Today is the anniversary of that afternoon in April a year ago that I first saw the strange and appealing doll(玩具娃娃)in the window of Abe Sheftel's toy shop on Third Avenue near Fifteenth Street, just around the corner from my office, where the plate on the door reads: Dr. Samuel Amory. I remember just how it was that day: the first hint of spring floated across the East River, mixing with the soft-coal smoke from the factories and the street smells of the poor neighborhood. As I turned the comer on my way to work and came to Sheftel's, I was made once more aware of the poor collection of toys in the dusty window, and I remembered the approaching birthday of a small niece of mine in Cleveland, to whom I was in the habit of sending modest gifts. Therefore, I stopped and examined the window to see if there might be anything suitable, and looked at the confusing collection of unappealing objects- a red toy fire engine, some lead soldiers, cheap baseballs, bottles of ink, pens, yellowed envelopes, and advertisements for soft-drinks. And thus it was that my eyes eventually came to rest upon the doll stored away in one corner, a doll with the strangest, most charming expression on her face. I could not wholly make her out, due to the shadows and the film of dust through which I was looking, but I was aware that a tremendous impression had been made upon me as though I had run into a person, as one does sometimes with a stranger, with whose personality one is deeply impressed.

单选题He was in a hurry and left things in a real ______.

单选题Being an intelligent boy, he ______ such a foolish mistake.

单选题In the United States, it is not customary to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p.m. If someone receives a call during sleeping hours, he assumes it"s a matter of life and death. The time chosen for the call communicates its importance. In social life, time plays a very important part. In the USA guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings arise between people from cultures that treat time differently; promptness (准时) is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the US no one would think of keeping a business friend waiting for an hour; it would be too impolite. A person who is 5 minutes late is expected to make a short apology. If he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.

单选题{{B}}21-25{{/B}} No woman can be too rich or too thin. This saying often attributed to the late Duchess (公爵夫人) of Windsor embodies much of the odd spirit of our times. Being thin is deemed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better--or worse--part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown relative dies suddenly in some distant land, leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent? All religions have certain days when people refrain from eating, and excessive eating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat--or even only somewhat overweight--is bad because it implies a lack of moral strength. Our obsession (迷恋) with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem--too much fat and a lack of fiber--than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vainglory (虚荣) .

单选题In the 1920s, demand for American farm products fell, as European countries began to recover from World War Ⅰ and instituted austerity (紧缩) programs to reduce their imports. The result was a sharp drop in farm prices. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they received for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1930s. In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers. President Hoover's successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was subsequently passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use. A deliberate scarcity of farm products was planned in an effort to raise prices. This law was declared unconstitutional by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people. However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation. The Roosevelt Administration believed that rebuilding the nation's soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (杂交) grain, and fertilizers.
