请仔细阅读下文，然后根据短文内容选择正确答案。

     If someone ask you, "What colour is the sky?"I think you will answer "Blue".I'm afraid that you will be
wrong. The sky has no colour. It looks blue because we are looking at blue sunlight. The sunlight is
shining on little bits of dust ( 灰尘) in the air.
     Is the sky full of air? I'm sure that you have asked this question, too. We know that there is air all
around the world, but we couldn't fly very high because as we go higher, the air gets thinner. If we go far
enough away from the earth, we find there is no air.
     Maybe we can answer some questions now. What is the sky? Where is it? It is all round the world. The
sky is space (宇宙空间). In space there is nothing, but only the sun, the moon, and all the stars.

    A. we think it is so
    B. we like this colour

2. The sky is _____.

    A. a star round it
    B. a big ball with air all
    C. full of dust
    D. space with  the sun, the moon and the stars

3. What makes us think the sky is blue?

    A. Dust in the sky.
    B. Air and blue light.
    C. Our own feeling.
    D. Both A and B.

    A. there's too much air in the high place

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. But from the moon, you can see a friendly sight. Our earth is shining more brightly than the other stars. It looks like a very large ball, coloured blue and green and brown.
