Answer 1

The sun is much bigger than the earth, and the earth is bigger than the moon. So the sun is
the biggest and the moon is the smallest. The earth goes round the sun day and night. It does at
30 kilometers a second.
The moon is our satellite (卫星) . It is also our neighbor. It goes round the earth all the time.
The moon goes at 8 kilometers a second. The moon can't give out light or heat itself, and nothing
can live on it.
Men live on the earth, which is going round itself all the time. Then the earth gives us lives, food,
water and so on. We must get on well with it.
