Scientists tell us so much about the moon, it is quite easy to tell what it is like. It’s certainly not a friendly place. As there is no air or water, there can be no life of any kind. Mile after mile there are only plains(平原) of dust with mountains around them above, the sun and the stars shine in the sky. If you step out of the mountains’ shadows(影子) it will mean moving from terrible cold into great heat. The moon is also a very silent world, for sound waves can only travel through air.
