more and more of the earth.  The moon is our neighbour in space. It is smaller than the earth.  Plants can't grow on the moon because there's no air or water on it.

       The moon hasn't its own light.  It shines back the light of the sun.  When the sun is shining on the side

of the moon that faces(朝向）us. it looks like a great round ball. We can't see the moon when the sun is

shining on the side of the moon that faces away from us.  In fact, the moon is far away fromus.  It is three

hundred and eighty thousand kilometers away from the earth.  Of course, we can fly to the moon in a

spaceship.  A spaceship flies very,  very fast.  It only takes more than three days to get there by spaceship!
