单选题Some pessimistic professors feel a little worried that mobile won't be useful in the near future. They see a day when all vehicles will be abolished. Other authorities, however, argue that the transportation will remain a leading way of urban travel in the foreseeable future. The motorcar will undoubtedly change significantly over the following 30 years. It should become smaller, safer, and more economical. What's more, the future car should be more pollution-free than current kinds, Without regarding its power source, the auto in the future will still be the main problem in urban traffic congestion(拥挤). One key to this issue is the automated high-speed system. As the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail. For the time it attaches to the rail, the vehicles will get electrically powered from the system, and control of the vehicle will pass to a central computer. The computer wilt then monitor all of the car's movements. The driver will use a phone to dial instructions about his terminal into the system. The computer will search for the best route, and show the right exit from the highway. It is estimated that an automated highway will be able to process 10,000 vehicles per hour.

单选题 You've probably had the experience of having someone fall in love with you when you didn't return the feeling. In such a case it's hard to know what to do. You want to discourage your admirer. Yet you don't want to be so clear in your efforts that you make an enemy of him. A friend of mine had this problem and handled (处理) it in the most tactful (得体的) way I've ever seen. Instead of telling the young man that she found it tiresome to have him around so much, she devoted herself to introducing him to every girl she knew. Whenever she had a date with him, she arranged (安排) for them to drop in at the home of one of her girl friends. A few weeks was all it took for him to click (一见如故) with one of these girls, and then everyone was happy. The new girl and the young man got along just fine and both of them were grateful to my friend for having brought them together. My friend was rid of a problem and she still had the young man as a friend, which was just what she wanted him to be. Of course this method may not work for you. You may have your own way of dealing with the problem. But whatever you decide to do, keep one thing in mind—the boy in question has feelings every bit as sensitive as your own. So try to find a way of discouraging him without hurting him.

单选题Mrs. Grey lived in the country, but she worked in London. She drove to the railway station in her car every morning, and left it in the station car park until she arrived back on the train in the evening. She was a careful driver, but one morning she was rather late, so she was going faster than usual when she had an accident in a narrow road not far from her home. What happened was that another car was coming in the opposite direction, and either that one or Mrs. Grey"s car was too far in the middle of the road, or perhaps both of them were. They ran into each other and were both damaged, although not enough to stop them from driving. Both Mrs. Grey and the other driver, who was a young man whom she had seen in the district but had not met, got out of their cars, and Mrs. Grey said, "I"m afraid I haven"t got time to waste on an accident this morning, as I have a very important appointment in town at nine, and I suppose you"re a busy man too." . "Yes, I am," the young man said, "but we"ll have to c. all the police for insurance purposes, won"t we? They won"t pay for the damage unless we have reported the accident to the police and they have come and seen what happened." "Yes, certainly," Mrs. Grey answered, "but I have something to suggest. We won"t be committing a crime if we go away now in our cars, and then come back to the scene of the accident, say, at six this evening, and put them in exactly the same positions as they are in now. Then we can call the police. They won"t know what time the accident happened, and the insurance companies won"t care either as long as we can send them a police report of the accident. " " What a good idea !" the young man said happily. "So I"ll be waiting here at six o"clock this evening. I won"t be late!" "Nor will I," Mrs. Grey answered. She and the young man exchanged visiting cards, and then each drove off to their work. When Mrs. Grey arrived at the station from London at a quarter to six that evening, she got into her car, drove to the place where the accident had happened, and found the young man waiting there in his car. They put both cars in exactly the same positions as they had been in after the accident, and then Mrs. Grey called the police, using the telephone in her car, as if the accident had just happened.
