题目内容
11.For people who are interested in space,nothing is more exciting than the idea of life on other planets.At first,when Mars showed signs of having life,everyone was excited.The idea has inspired many films and stories including The Martian(《火星救援》),which shows a man struggling to survive on Mars.But would it actually be possible to live there?While the idea of living on Mars is great,the reality does not look as good.Mars does not have a friendly atmosphere(大气) for humans.There is very little oxygen(氧气)there,and because of the distance from the sun,It is also very cold.The temperature on Mars can be-62℃on average.This is much too cold for humans,
However,scientists say it might be possible to live there without an atmosphere.Mars has a similar amount of daytime to Earth,which means there's enough sunlight to grow plants inside safe buildings.However they would have to grow in soil from Earth.Mars does not have a strong enough atmosphere to stop the radiation(辐射) from space,which makes it dangerous to grow things in the soil.
Also,the radiation causes problems to our health.One way we could survive the radiation and cold temperature would be to build homes under the ground or within the rocks(岩石) on the planet.These would give humans the heat and protection the planet doesn't have.
Although it's a long time before we would be able to live on Mars,NASA is hoping to make some progress within the next 20years.

分析 短文主要介绍了火星上的一些自然环境.那里的氧气很少,温度很低.没有足够强大的大气层来阻止来自太空的辐射,为了保护人类免受辐射,需要在地下或岩石内建造我们的家园.美国国家航空和宇宙航行局希望在未来20年内取得一些进展.
解答 32.C 细节理解题.根据短文中第一段的句子"That might be why the movie The Martian (《火星救援》) is so popular.It shows an astronaut struggling to live on Mars."可知,《火星救援》这部电影介绍了有关在火星上生活的话题.答案为C.
33.C 细节判断题.根据短文中的句子"And because of its distance from the sun,it is also very cold.The temperature on Mars can be-62 degrees on average.This is much too cold for humans."可推测,火星离太阳比地球更远.故C答案错误.
34.B 细节理解题.根据文章内容which means there's enough sunlight to grow plants inside safe buildings可知,人们在Mars生存下去的条件是有充足的阳光.故选B.
35.C段落大意题.根据短文中的句子"If we want to live there healthily,we need to build our homes under the ground or within the rocks on the planet.This would protect humans from the radiation and also some heat."可知,此段主要介绍了在火星上如何避免不好的状况,免受辐射.故答案为C.
