题目内容：

Of all the stars the sun is the nearest to the earth. Millions of other stars are even bigger and brighter than the sun. They look small only because they are much farther away. You can’t see them in the daytime. But if you go out at night, you’ll be able to see thousands of them.

The earth is one of the sun’s planets, and the moon is our nearest neighbor in space. Men have visited it already. No man has traveled farther than the moon, but spaceship(宇宙飞船) without people have reached other planets.

Many countries have sent up man-made satellites(人造卫星) to circle the earth. With their help, people have done much research in many fields of science.
