单选题Three men got to Dover station a few minutes after nine o'clock one evening. They asked a guard, "What time is the next train for London?" The guard said, "You've just missed one. A train goes every hour. The next one is at ten o'clock.: "That's all right," they said, "We'll go and have a drink." So off they went to a bar (酒吧间). A minute or two after ten o'clock they came running and asked the guard, "Has the train gone?" "Yes," the guard said. "It went at ten, as I told you. The next one is at eleven o'clock." "That's all right," they said again. "We'll go and have another drink." So they went back to the bar. They missed the eleven o'clock train in the same way. Then the guard said, "Now, the next train is the last one. If you miss that train, you won't get to London tonight." Twelve o'clock came, and the last train was just starting out when the three of them came out of the bar running as fast as they could. Two of them got in the train just as it was leaving, but the third one didn't run fast enough, and the train went out leaving him behind. He stood there looking at the train and laughing, as if (好像) to miss a train was the best joke in the world. The guard went up to him and said, "I told you that this was the last train. Why didn't you come earlier?" The man kept laughing until tears came into his eyes. Then he caught hold of the guard and said, "Did you see the two men get into the train and leave me here?" "Yes, I did." "Well, I was the only one to leave for London. They were here only to see me off!/

单选题C The world is not only hungry, but also thirsty for water. This may seem strange to you, since nearly 75 percent of the earth's surface is covered with water. But about 97 percent of this huge amount is seawater, or salt water. Man can only drink and use the other 3 percent—the fresh water that comes from rivers and lakes. Some of it has been polluted and unfit for drinking. However, as things stand today, this small amount of flesh water is still enough for us. But our need for water is increasing rapidly almost day by day. Only if we take steps to deal with this problem now, can we avoid (避免) a serious worldwide water shortage later on so we all have to learn how to stop wasting our precious water. One of the steps we should take is to develop ways of reusing water. Today in most large cities water is used only once and then discharged (使流走). But it is possible to purify (净化) the water so that it can be used again. But even if every large city purified end reused its water, we still would not have enough; where could we turn next? To the oceans! That is certainly a possible solution. All we'd have to do is to remove the salt. This process is already in use in many parts of the world.

单选题Beijing's sky watchers will see with their own eyes a bright com- et (彗星) all night long. Comet e/1996 b2(Hyakutake) was first observed by Hyakutake, a Japanese amateur (业余的) astronomer (天文学家) , on January 30, 1996. It can be seen with the naked eyes (肉眼) over China, Europe and other northern areas at night through the last week of March and first ten days of April. On march 25, it was closed to the earth and the sun. What is more exciting is that there will be two more rare events in the sky, it is predicted (预言) that another comet, HaleBopp, found on July 23, 1995, by Americans Alan Hale and Thomas Bopp, is expected to pass over the northern part of Heilongjiang province in March 1997. The comet, estimated to be 10×15 kilometres in size, will not return for 3 000 years. What is even more rare is that a total solar eclipse (日蚀) is expected to occur on March 9, 1997, over Mongolia, Siberia and northern Heilongjiang province. When the sky turns dark, people should be able to see the eclipse and the bright comet HaleBopp at the same time. An observation (观察,评论) trip to Mohe, Heilongjiang Province, is being organized for the March 1997 sky events, as well as a nationwide astrophoto competition (竞赛).
