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（大氣） for humans．There is very little oxygen（氧氣）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（輻射） 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（巖石） 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 短文主要介紹了火星上的一些自然環境．那里的氧氣很少，溫度很低．沒有足夠強大的大氣層來阻止來自太空的輻射，為了保護人類免受輻射，需要在地下或巖石內建造我們的家園．美國國家航空和宇宙航行局希望在未來20年內取得一些進展．
解答 32．C 細節理解題．根據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》這部電影介紹了有關在火星上生活的話題．答案為C．
33．C 細節判斷題．根據短文中的句子"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．"可推測，火星離太陽比地球更遠．故C答案錯誤．
34．B 細節理解題．根據文章內容which means there's enough sunlight to grow plants inside safe buildings可知，人們在Mars生存下去的條件是有充足的陽光．故選B．
35．C段落大意題．根據短文中的句子"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，此段主要介紹了在火星上如何避免不好的狀況，免受輻射．故答案為C．
