二、阅读理解（★★★）
Scientists always want 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 humans 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 a rocket（火箭）.
There is gas 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 far out into space. They send spacecrafts（航天器）to the Moon. Spacecrafts with humans in them have been to the Moon. Several spacecrafts without humans in them have flown to another planet much farther away from the Moon. One day humans may be able to go to any place in space.

答案
1~5 D B A A B
解析
【分析】
先通读全文，理解文章围绕科学家探索宇宙、介绍火箭作用及太空探索相关内容展开。逐题分析：1题需定位原文找科学家对月球的已知信息；2题定位原文找飞机不能飞月球的原因；3题分析第四段内容判断主旨；4题结合文章去月球的工具，识别对应插图；5题定位原文判断正确选项。
【解析】
1. 细节理解题：根据原文第二段“They knew how big it was and how far away it was from the Earth.”，可知科学家知道月球离地球的距离，对应选项D，故选D。
2. 细节理解题：根据原文第三段“A plane cannot fly to the Moon because the air reaches only 240 kilometres away from the Earth.”，可知飞机不能飞月球是因为地球240公里外无空气，对应选项B，故选B。
3. 主旨大意题：第四段主要介绍火箭的工作原理，即火箭如何飞行，对应选项A，故选A。
4. 细节理解题：根据文章，去月球需用火箭，插图中A是火箭，B是飞机、C是卫星、D是轮船，对应选项A，故选A。
5. 细节理解题：根据原文最后一句“One day humans may be able to go to any place in space.”，可知作者认为人类有可能去太空任何地方，对应选项B，故选B。
【答案】
1~5 D B A A B
