                                                                       The Moon

     Three hundred and eighty thousand kilometres away from the earth, the moon is man's closest neighbor

in the universe. Its surface is as large as Asia. Though so far away, the moon has a strong influence on the

ecological balance on the earth. For example, partly because of the moon's gravity, our seas and oceans have

tides.

     Nearly forty years ago, man's dream of reaching the moon was realized when American astronaut Neil

Armstrong stepped onto the moon's surface. As Armstrong said, it was a small step for a man, but a giant

leap for mankind. Just think of the past when our forebears could hardly find enough to keep alive!

     Understanding the moon is of great significance. Since there is no water and no air there, the moon is an

ideal place from which to observe the universe. A huge astronomical telescope has been installed on the moon.

And the moon's solar energy can be used more fully than the earth's. Finally there are the moon's rich mineral

resources. It is no exaggeration to say that the moon is a mini-earth in terms of mineral resources.

     Maybe it won't be long before man can benefit from the development of the moon's resources.
