题目内容
A few days ago, few people knew his name or his face. But last Thursday, when he came back to the earth after a 21-hour trip to space, Yang Liwei's smile was seen across the world.
The 38-year-old astronaut (宇航员) was sent into space at 9:00 am, last Wednesday by China's Shenzhou V Spaceship, and it travelled round the earth 14 times. He landed safely at 6:23 am, the next day. That made China the third country to successfully send a person into space, after the former Soviet Union and the USA.
Yang was pleased with his job. “I have seen many landing scenes ever before on video tapes, and I think ours was one of the most successful,” he said on a special plane to Beijing after landing.
Anybody who saw the breaking-up of the US space plane named Columbia in February of 2003 knew that Yang was in great danger.
Yang experienced very high temperature, while the gravitational forces (地心引力) on taking off and landing were strong enough to make tears from his eyes.
He has spent five years training to become a spaceman after 1350 hours' flying in the air. Although it was hard work, Yang loved it. Yang's success was well worth all the hard work. Yang has become China's first spaceman.

(1) 通读全文可知杨利伟花了21小时绕地球14圈，at a time意为“一次”，题意是说神州五号飞船绕地球一圈需多长时间，故应用21小时×60分钟÷14圈＝90 (分钟)，因此选D。 (2) 从文章第二段可知，中国、前苏联和美国都成功地向太空发射过载人飞船，故可知有三个国家，因此选C。 (3) 从文章第五段可知，宇宙飞船脱离地球和着陆时，宇航员不得不经历高温，故选A。 (4) 从文章第二段第一句话可知，是神州五号飞船把杨利伟送上了太空，故选A。 (5) 从文章最后一段第一句话He has spent five years training to become a spaceman after 1350 hours' flying in the air. 可知杨利伟花了5年的时间训练，故选B。 |
