单选题What difference does it make if we read texts displayed on a computer screen instead of on paper printed with ink? The computer certainly does not guarantee deeper comprehension, greater subtlety of mind, or a wider range of imaginative reference. The mediation of a computer, however, puts new powers at the disposal of intelligence. For one thing, the computer itself can do simple reading--as I have noted, it can "read" an immense body of literature in search of designated(指定的)words. As anyone knows who has ever spent days in libraries in search of errant information, simply identifying relevant sources absorbs inordinate amounts of time in research. The objection may be raised that a search of texts by computer may block the occasional(偶然发现的)discoveries that occur while browsing in the stacks of great libraries. No member of the academy need fear that the use of a computer will keep him from the stacks, but browsing is, if anything, easier if texts can be called up on a screen in the serenity(宁静)of one's chosen surroundings. The great deficiency of libraries, as we know them, is that while titles are catalogued, the libraries have no master indexes of the contents of books. Individual volumes, it is true r have indexes, often of inferior quality, but even the best indexes must be examined one at a time. The great advantage of the electronic library is that a computer could search and analyze its contents without proceeding volume by volume. As work in artificial intelligence develops, computer systems may also become adept at more complex tasks, such as summarizing texts, which has been accomplished experimentally.

单选题It was 7:00 am in Kyoto, Japan, and the taxi company had just called a second time to say they couldn't find my house. Once again I spelt out directions even a blind person could follow. I glanced impatiently at my watch, and waited. Only two hours remained until my flight left--and it was an hour-and-a-haft trip to the airport. Outside, heavy rains were pouring down. My house was so far north in the city that buses pass only three times a day. The telephone rang again. "Terribly sorry," began the man at the taxi company. Then I realized that the taxi company, flooded with calls, could only offer in-city runs. I had heard this happens when the weather gets bad. I shouted into the phone that I had a plane to catch and I would meet the taxi outside my house. Standing in the wind-driven rain, I looked up and down the road. No taxi. A car went by, the driver and passenger staring at the crazy foreigner in the downpour. Finally a white car appeared and pulled to a stop. A young man throw open the door, waving for me to get in. Shaking with cold and anger, I climbed in. In the most polite Japanese, the man said he was called Mike, with whom I had spoken three times that morning. He had left his post in the office and raced here in his personal car. He apologized again, but did not explain why a taxi would not pick me up. Delivering me straight to the air- port, he refused the 2,000 yen I pressed into his hand. A few hours later, as the storm-delayed 727 took off, I opened the newspaper. On the second page my eyes caught the headline of a short article: Taxi Strike Begins This Morning in Kyoto.

单选题America has had many presidents who have been famous all over the world. People from other countries know the names Washington, Kennedy and so on. However, many men who have served as president of the United States have not been famous in other parts of the world. One example is J. Q. Adams, the sixth man to serve as U.S. president. Very little happened while Adams was president. It was an unhappy time for him, and he wasn't very effective, when his term ended, he went back to the Congress and served as a representative (众议院议员). While he was in Congress, people began to respect him more than they had done while he was president. Adams was strongly against slavery and tried to outlaw it in Washington D. C. People began to look back on his presidency with a different view. Now they saw that he was an independent man with high ideal who loved his country and hated slavery. Adams died in 1848 while speaking in the House of Representative.

单选题Water, water everywhere. It lasted almost two months, but in August it ended. It left 45 people dead and $10 billion worth of damage in nine states of the USA. It was quite a big Mississippi flood ever recorded. In St. Louis, Missouri, 9,000 people were forced to leave their homes while the city was in danger. St. Louis is just downriver from the points where the Missouri and Illinois Rivers flow into the Mississippi. All the three rivers were flooding. But the city escaped the worst when levees broke upriver. A levee is built of river sand and clay. Eleven miles of flood walls were built in the late 1960s. The walls are 18 inches thick and 5 to 22 feet high. They were designed to protect against a 52-foot flood. In St. Louis, water almost reached the top of flood walls. It measured 49.4 feet.

单选题 The success story started in northern Italy towards the end of the Second World War. Leone Benetton had a bicycle rental (租赁) business in the town of Treviso. He wanted his oldest son Luciano to study and become a doctor. After Leone died, the family was poor and Luciano decided to leave school and get a job. He found work in a clothing store but soon had his own ideas and started a family clothing company producing colorful woolen sweaters for people only used to wearing dull colors. Shops selling only Benetton sweaters opened in many Italian cities and by 1974 there were stores in France, Germany and Belgium. It was clear that at this stage the success of the Benetton business lay in the strength of the family. In 1975 Luciano married the 20-year-old Marina Salomon who worked in one of his shops. After careful research, Benetton opened his first shop in the USA, in Manhattan, New York, where it attracted some very special customers including Princess Diana and Jackie Onassis. In 1982 Luciano was introduced to Oliviero Toscani, the photographer who was to change the image (形象) of Benetton forever. Although Benetton was growing very quickly, they needed an international image and for this reason in the early 1980s they decided to provide money for Formula 1 motor racing. This was followed by the advertising campaigns (广告攻势) for which the company became famous. Luciano Benetton succeeded in turning the company he started in the 1950s into one of the world's most successful businesses but he paid a high personal price. He spent so much of his life working and traveling that he lost touch with his family and friends.
