单选题That afternoon Molly almost danced along the street, as she walked home with her father from the station. They had seen Mrs. Gibson and Cynthia off to London. She wished her stepmother would take herself off to London much more often. "Well now, Dad," she said, "I''m going to have you all to myself for a whole week. You must be very obedient. " "I hope you aren''t going to boss me, Molly. You''re walking me out of breath already. We mustn''t pass Mrs. Goodmays in our hurry. "They crossed the street to speak to Mrs. Goodmays, one of the Doctor''s patients. " We''re just been seeing my wife and her daughter off to London. They''ve gone up for a week. " "Dear me, to London, and only for a week!" Said Mrs. Goodmays, with surprise. "It seems hardly worth the packing. It''ll be lonely for you, Molly, without your stepsister. " "Yes," said Molly, suddenly feeling as if she ought to have taken this view of the case. " I''ll miss Cynthia. " "And you, Dr. Gibson, I hope you won''t feel like widower once again. You must come and have supper with me one evening. What about Tuesday?" Dr. Gibson felt a sharp blow on his leg from the toe of Molly''s shoe, but even so he accepted the invitation, much to the old lady''s satisfaction. A moment later Molly said to him, " How could you go and waste one of our precious evening! We''ve only got five now. I''ve been planning all sorts of things for us to do tonight. " "What sort of things?" "Oh, I don''t know. Things you used to like, "she looked at him boldly. "Forbidden things now. " Her father''s eyes lit up, but his face remained serious. " I''m not going to be pulled down, Molly. With hard work and sensible guidance I''ve reached a very fair height of civilized behavior, and there I''m going to stay. " "Oh, no, you''re not. We''re having bread and cheese for supper tonight, in armchairs in front of the TV! And you shall wear your dressing-gown at breakfast tomorrow — and every morning for a week! And you shall read the paper at the dining-table \ That''s only a start. I haven''t finished by a long way yet. "

单选题Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future. The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system. When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car"s movements. The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer ( 蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day high-way.
