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 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 a rocket（火箭）. 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 space. Rockets with men in them have been to the moon.Several rockets without men in them have flown to another planet（行星）much farther away than the moon. One day rockets may be able to go to any place in space.

科学家们一直想知道更多关於宇宙。年前他们知道关於月球的很多事情。他们知道这是多大和多远远离地球。但是他们想要更多地瞭解它。他们认为最好的方法是，把人送到月球上去。月球是距离地球约 384,000 公里。一架飞机不能飞向月亮，因为空气到达距地球仅 240 公里。但即使没有空气，东西能飞。这就是 rocket（火箭）。火箭是怎麼飞的？火箭有 gas（气体）in。当气体被火箭里面很热，它将冲出火箭，最终使它的火箭上飞上天空。火箭可以进入太空飞出。火箭与男子在他们一直到月球上去。男子在他们没有几个火箭飞向另一个 planet（行星）much 远比月球。一天火箭可能能够在空间中的任何地方去。
