题目内容
Scientists wanted to know more about the moon. They thought the best way was to send men to the moon. The moon is about 384,000 kilometers away from the earth .A plane can not fly to the moon because the air reaches only 240 kilometers 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 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. Rockets with spaceships with men in them have been to the moon. Several rockets with spaceships with men have flown to another planet much farther away than the moon. One day rockets may be able to go to any places in the space.
