An Unfriendly Place一个不友好的地方

    The moon is an unfriendly place.So there is neither air nor water,nor life of any kind.There is not much variety of acenery either.The sun and stars shine in the black sky and the extreme temperatures break rocks away from the surface of the mountains.Sound waves can only travel through the air,so the moon is a very silent world.The earth is shining more brightly than the stars.It looks like an immense ball.
