Question

【题目】阅读理解
A
　
　　 Scientists have always wanted to know more about the universe.
　　Years ago they knew many things about the moon. They knew how big it was and how far away it was from the Earth. But they wanted to know more about it. They thought the best way was to send men to the moon.
　　The moon is about 384,000 kilometres away from the Earth. A plane cannot fly to the moon, because the air reaches only 240 kilometres away from the Earth. But something can fly even when there is no air. That is the rocket.
　　How does a rocket fly? There is gas (气体) in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.
　　Rockets can fly out into the space. Rockets with men in them have been to the moon. Several satellites without men in them have flown to another planet much farther away than the moon. One day rockets may be able to go to any place in space.

B.there is no gas in the plane
C.the plane is not strong enough
D.the plane must be driven by a man
（4）The hot gas in the rocket is used for ______.
A.keeping the air in the rocket fresh

【解析】本文讲述科学家对宇宙的探索，人类已经飞上了月球，飞机不能飞上月球因为没有大气，火箭借助对空气的推力上天，火箭能飞进太空，是将来太空旅行成为可能。第一句是本文的中心句。
（1）细节理解。根据They knew how big it was and how far away it was from the Earth.可知Ｄ正确。
（２）细节理解。根据第三段The moon is about 384,000 kilometres away from the Earth.可知D正确。
（3）细节理解。根据because the air reaches only 240 kilometres away from the Earth可知没有空气的地方飞机无法飞行，故选Ａ。
（４）细节理解。根据倒数第二段When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.可知火箭里面的气体变热，会推动火箭飞上填空，故选C。
（5）细节理解。根据最后一段Several satellites without men in them have flown to another planet much farther away than the moon可知无人卫星已经飞上了其他行星，所以选Ｄ。
