1 . When we talked about the space,we know the universe means the earth, the sun, the moon, the stars and so on in space. Many of the stars are so far away that we can’t see them.
Through our geography lessons, we know the earth (1)goes around the sun, and the moon goes around the earth.
We have day and night because the earth keeps moving all the time. Just because the moon is closer to the earth than the sun, it looks much bigger than the sun.(2)The sun is bright enough to give out very strong light. The moon can’t give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the sun.(3)But in fact the stars are much bigger and brighter than the moon.
(4)在宇宙中仍然有许多其他的行星。But of all these planets, only on the earth there are living things. People on the earth have studied the space all the time. They’ve sent many spaceships into the space many times. On November 3 and 14, 2011, Chinese scientists let Shenzhou Ⅷ successfully dock with(对接) the Tiangong Ⅰ twice. This is one of the greatest events in the history of China’s space.

3 . Our sun is a star, and nine worlds (天体) move round it. Worlds like these are planets. But there are other stars, other suns, not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. but we haven’t been anymore. The stars are too far away from us. Stars give out light, but the planets don’t have any light of their own. So we can’t see them. They are too far, and too dark. Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this. Then we know that the star has a planet. For example, Barnard’s Star is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have known Bernard’s Star for many years, and now we are sure it has a planet.
