3.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 本文是一篇新聞報道類閱讀,屬于對于對空間感興趣的人,沒有什么比其他行星上的生活思想更加激動人心.首先,當火星出現(xiàn)生命跡象時,每個人都很興奮.這個想法啟發(fā)了許多電影和故事,包括火星救援,這顯示一名男子正努力在火星上生存,但實際上是否可以住在那里?本文以此展開,主要討論了在火星生活是否可能地問題.
解答 32.C.推理判斷題.根據(jù)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?以及下文可以推測出,通過提及電影火星救援是為了引出生活在火星的主題.故選C.
33.C.細節(jié)理解題.根據(jù)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.可知,植物在火星上無法存活.故選C.
34.B.細節(jié)理解題.根據(jù)Mars has a similar amount of daytime to Earth,which means there's enough sunlight to grow plants inside safe buildings.可知,火星可以得到足夠的陽光,這是一個有利的條件.故選B.
35.C.段落大意題.根據(jù)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.可知,本段主要介紹了輻射會導(dǎo)致什么問題.故選C.
點評 本文是一篇新聞報道類閱讀,題目涉及多道主旨大意題,細節(jié)理解題,推理判斷題.做題時學(xué)生應(yīng)仔細閱讀原文,把握文章主要內(nèi)容,聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義,從中選出正確答案,一定要做到有理有據(jù),切忌胡亂猜測.
