【推荐1】Do you know something about the moon? You can see it at n    1    . Sometimes it looks round and bright. It also looks quite near. B    2     the moon is very f    3     from the earth. If you take a spaceship, you will get there in more than three days. The spaceship goes very fast, at 11 kilometers a second. In 1969 two Americans got on the moon by spaceship.

There are no living things on the moon b    4     there is no air or water there. That's why people can't l    5     there. But you may know you can jump much higher there than on the earth. It's fun, isn't it?

I hope some day we Chinese will get to the moon, too.

We know much about the universe(宇宙). It means the earth, the sun, the moon and the stars and the spaces between them.

Most of the stars are bigger than the moon, but they look much     1    . Because they are far     2     from the earth. At night, the moon is high in the sky like a light. But the moon has no light of     3     own. The light of the moon comes from the sun. The sun gives us light, heat and life. And the plants, animals and men will die     4    the sun.

The earth is going round itself all the time.     5     the part of the earth turns to the sun, it is day. The opposite part of the earth is night.

The earth is our homeland. We should love it.
