(19) One thing about the moon many people don’ t know is that it has a lot of garbage on its surface, leftover from human space exploration. But how much garbage exactly have humans left on the moon? It’ s hard to be accurate, but the trash likely weighs more than 181,000 kilograms on earth. Much of it was left by American astronauts, who landed on the lunar surface between 1969 and 1972 during NASA’ s Apollo Missions. The other rubbish comes from missions that did not have human crews. These missions were conducted by various space exploring agencies, including those from the US, Russia, Japan, India and Europe. Many of the older pieces are equipment sent to learn about the moon. The equipment stayed there after its mission ended.
The moon is also home to lunar orbiters that nabbed the moon before they crashed into its surface, adding to the garbage heap. (20) The objects left by the Apollo astronauts included the equipment that was no longer needed. Bringing back unneeded equipment would have used up precious resources such as fuel. But as the saying goes, "one person’ s trash is another’ s treasure" , (21) researchers can study the garbage left on the moon to see how its materials weathered the radiation and vacuum of space overtime. Moreover, some of the objects on the moon are still being used, including a laser range reflector left by the Apollo 11 crew.
Questions 19 to 21 are based on the passage you have just heard.
19. What does the passage say maybe unknown to many people?
20. Why has a lot of equipment been left on the moon?
21. What can researchers do with the garbage on the moon?
选项
A、Record details of space exploration.
B、Monitor the change of lunar weather.
C、Study the effect of radiation and vacuum on its materials.
D、Explore the possibility of human settlement on the moon.
答案
C
解析
题干问的是研究者可以利用月球垃圾做什么。短文中提到,研究者会研究月球上的垃圾是如何长时间不受辐射和真空影响的,故答案为C(研究辐射和真空对它的影响)。A项(记录太空探索的细节)、B项(监控月球天气的变化)和D项(探索人类定居月球的可能性)均与原文内容不符,故排除。
