A It was 7 a.m. 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-half 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 rea-lized 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,　driver and passenger staring at the crazy foreigner in the downpour.　Finally a white car appeared and pulled to a stop. A young man threw 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 airport, he refused the 2000 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." 56. Why did the writer call a taxi early in the morning? [ A ] There were few taxis in town. [ B ] He was unable to find the airport. [ C ] He wanted to catch a plane. [ D ] All the buses stopped because of the rain. 57. What was the reason for the taxi company not being able to pick him up? [ A ] The taxi drivers refused to work. [ B ] The writer didn' t give the correct address. [ C ] More people were riding in taxis on rainy days. [ D ] The taxi drivers didn' t like to drive long distance. 58. The writer got to the airport . [ A ] by getting a lift in a passing car [ B ] with the help of Mike from the post office [ C ] by riding in Mike' s car from the taxi company [ D ] with the help of a taxi driver sent by his company 59. We can learn from the text that the driver is . [ A ] quick-minded at taking actions [ B ] warm-hearted toward people [ C ] unfamiliar with the road [ D ] a self-employed driver B She once said:"When people ask me if writing has been a hard or easy road I always answer with the famous saying, "the end is nothing; the road is all. ' That is what I mean when I say writing has been a pleasure. I have never faced the type-writer(打字机) with the thought that one more task had to be done. " Like most writers, Willa Cather did not write books for the money that they brought her, but rather for the pleasure that came in their writing. Her works were, like her, simple and full of the vigor( 活⼒ ) of her days in Nebraska, where she grew from childhood to young womanhood and where she developed a deep love for the treeless land of the Great Plains with its wild flowers, wheat fields and rivers. "It' s a rather strange thing about the flat country," she wrote later. "It takes hold of you, or it leaves you perfectly cold. A great many people find it very dull; they like a church tower, an old factory, a waterfall, country all made to look like a German, Christmas card... But when I come to the open plains, something happens. I'm home. I breathe differently. " 60. Willa Cather wrote because she found writing . [ A ] simple and lively [ B ] interesting and enjoyable [ C ] neither too hard nor too easy [ D ]opened up a road to, success 61. What did Cather mean by "the end is nothing ;the road is all"? [ A ] Writing is the only path to successs. [ B ] I feel happy when I finish writing a book. [ C ] I enjoy writing whether it is hard or easy. [ D ] Writing itself, not its result, is important. 62. What was the place like where Cather grew up? [ A ] It was cold, plain and without a church. [ B ] It was a colorful world of wild flowers. [ C ] It was like a German Christmas card [ D ] It was vast, open, flat and wild. 63. When she said "It takes hold of you, or it leaves you perfertly cold", Willa Gather meant . [ A ] you either love the place or hate it [ B ] you decide either to stay or to leave [ C ] some find the place warm; others find it cold [ D ] some find the place peaceful; others find it wild 64. What happens when Cather comes to the open plains? [ A ] She breathes differently from others: [ B ] She wants to make the place her home. [ C ] She finds the place similar to her home. [ D ] She feels completely comfortable. C You want to know where the safest place for young children is in the car ? Experts .(专家), all say the back seat is the safest place , for a child of any age. In the back seat, the child is farthest away from the force or effect of a head-on collision (迎头撞击), which can cause the most injuries(伤害). Just as important ， the child in the back seat is. removed from the passenger air bag, if there is any. If your child is under8 years of age and weighs no more, than 80 pounds, it is necessary to fit your car with a special child safety seat. The child safety seat comes in three types or sizes: the first type is designed for babies from birth to one year of age, until the baby weighs about 20 pounds; the second size is for children between one and four years of age, who weigh between 20 and 40 pounds; the third, kind is used by older children big enough to use the car' s belt system. Moreover, .all these safety seats must be fitted and held in place on the car' s back seat. If your child does need your attention while .you are driving, don' t look back with only one hand on the wheel. Just pull over. 65. This text mainly discusses . [ A ] how a child can be kept safe while riding in a car [ B ] why the back seat i s t h e s a f e s t p l a c e i n a c a r b r > 0 0 [ C ] h o w a c h i l d s a f e t y s e a t c a n p r o t e c t a c h i l d b r > 0 0 [ D ] w h a t c a u s e s p a s s e n g e r s t h e m o s t i n j u r i e s / p > p > 0 0 6 6 .

一、改错题(17分)【题目】这是一个对原文进行加密的程序，原文全部由大写字母及空格与合法的标点符号组成，加密方法是每个字母依所在原文中的排列次序，奇数位字符按ASCII代码序依次前移5位，如字母F前移5位则变为A，但E前移后则变为Z，D则变为Y，依此类推；偶数位字符，则按ASCII代码序依次后移5位，如字母A后移5位则变为F，但Y后移后则变为D，Z则变为E，依此类推。

原文中的空格与合法的标点符号保持不变(下图为参考界面)。
