there is the sun, the moon, the earth and a g
earth and many good stars.
Through our geography lessons, we know the earth goes around the sun, and the moon goes around the earth. We have day and night because the earth keeps turning all the time. When our part of the earth turns to the sun, it is day. When our part of the earth turns away from the sun, it is night.
Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer.
The sun is big 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. The moon looks much bigger and brighter than the stars. But actually (事实上) the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are further away from the earth.
There are many other planets in
the universe. But of all the planets,
only on the earth there are living
things and people can only live on
the earth, too. But at 9:00 a.m.
on October 15th，2003, Chinese

假如你昨晚做了一个梦，你和Jim都是宇航员，你们乘坐宇宙飞船飞进了太空， 到达了火星。
提示词： Mars, Martians (火星人), many stars, no air or water
I had a dream last night. My friend Jim and I were astronauts. We flew into space by spaceship. We saw a lot of stars there and we also got to Mars. There was no water or air on Mars. However, we met some Martians. They were very friendly to us. Soon we became good friends. We invited them to the earth one day. When we were leaving Mars, Mum asked me to wake up. What an interesting dream!
