The mission will accomplish the firstspacewalk by Chinese astronauts.“All the major sy stems involved in the launching are now in the final preparation. The main tests for the spacecraft, the Long-March II-F rocket, suits for the space walk and a satellite accompanying the fly have also been finished,” said the spokesman. In addition, the gr ound control system is fully prepared, including the launch site, the landing site, and the communication for observation and control.When Shenzhou-7 enters its orbit, one of the three astronauts will conduct a space walk, said Zhao Changxi, a senior scientist with the project, earlier. According to Zhao, cameras would be fixed outside and inside of the ship for live broadcasting of the space walk.While the last mission of Shenzhou-6, with a crew of two, was aimed at several days of manned flight, this time the task might be more stringent as one of its main goals is the space walk. Earlier reports said a crew of six astronauts had been chosen for the mission, with three manning the spacecraft and three substitutes.China successfully put two manned spacecrafts into orbit in 2003 and 2020 respectively, becoming the third country to send an astronaut into space after the United States and the former Soviet Union (now Russia).1. What is the main idea of the passage?A. Shenzhou-7 is better equipped than the last two spaceships.B. Shenzhou-7 will be more successful than the last two launches.C. All the systems involved in the launching have been prepared.D. China is ready for the launching of Shenzhou-7.2. We can learn from the passage ________.A. This will be the third time for Chinese astronauts to have a space walkB. Three of the six astronauts chosen for the mission will walk in spaceC. The space walk will be live broadcasted on TVD. Everything has been prepared except communication system3. The underlined word“ stringent” most probably means _______.A. challengingB. encouragingC. incitingD. convincingBAstronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone.The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes, man knew little about the moon. They did not know that the planet called Saturn(土星) had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture(海王星), the last of eight planets to be discovered, was not seen until 1846.Before the spectroscope(分光镜), man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn’t know that radio noises came from far out in space.Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy.4. Thousands of years ago, people observed the stars with the limitation of their _____.A eyesight B. land C. wealth D. knowledge5.

Over 2,000 years ago, the Greeks knew the planet Saturn had rings around it.7. This passage mainly talks about _____.A. tools used in astronomyB. the development of astronomy in the last 50 yearsC. Greeks’ achievements in astronomyD. new tools and the development of astronomy编印：屠小平 101—121 2020/05/11参考答案：一：ABBAD DACAA二：1. prevent, from 2. give birth to 3. as well as 4. as a result of 5. in time 6. depends on7. different from 8. in their turn 9. breaks out 10. cheer up 三: 1. that as a result of, break out 2. cheer her up, is to 3. three times, large, threes larger than, three times the size of 4. watch out, into trouble 5. broke out, luckily/fortunately 6.
