Question

The sun looks like a shiny plate, but it is really a big ball. It is always giving off light. Its flames (火焰) are very much hotter and bigger than any fire on the earth. The sun has a family. It is the biggest member in the family.

The moon is a ball, too, like the sun and the earth. Sometimes it looks as round as a plate, sometimes it looks like half a plate, or like a thin slice(片) of yellow melon(瓜).But whether you can see all of it or not, the moon is always round. Part of it is dark because it is always turned away from the sun. The moon has no light of its own. Moon light is only sunlight shining on the moon.

The moon is much smaller than the sun, even smaller than the stars. As the moon is nearer to us, it looks bigger. All day the stars are in the sky, but the light from the sun is so bright that you can not see them. Stars look as tiny(极小) as pinheads(针头), but some are even bigger than the sun. The sun looks big because it is closer than the other stars. The farther away a thing is, the smaller it looks, even if(即使) it is really very big.
