The earth moves round the sun, and the moon moves round the earth. When our part (部分) of the earth
turns to the sun, it is day. When our part of the earth turns away from the sun, it is night. The sun is much
bigger than the moon. But sometimes the moon looks bigger than the sun, because it's much nearer to the earth. The sun is very bright. It gives a very strong light. The moon looks quite bright, too. But it doesn't give any
