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.1. We often think the sky is blue because _____.    A. we think it is so
    B. we like this colour
    C. we don"t have other colours
    D. we don"t like other colours2. 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 stars3. 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.4. We can"t fly very high because _____.    A. there"s too much air in the high place
    B. the high sky is full of dirty air
    C. there is no air in the high enough sky
    D. the sun is too hot5. The writer of the passage _____.    A. tells us something about the sky

阅读理解。     Scientists have always wanted to know more about the universe.
     Years ago they knew many things about the moon. They knew how big it was and how far away it was from the earth. But they wanted to know more about it. They thought the best way was to send men to the moon.
     The moon is about 384 000 kilometers away from the earth. A plane cannot fly to the moon because the air reaches only 240 kilometers away from the earth. But something can fly even when there is no air. That is a rocket(火箭)
      How does a rocket fly? There is gas(气体)in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.
      Rockets can fly far out into space. Rockets with men in them have been to the moon. Several rockets without men in them have flown to another planet(行星)much farther away than the moon. One day rockets may be able to go to any place in space.1. Scientists have known _____ the moon is.A. how long
