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.

     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.

     If someone asks you "What color is the sky", I think your answer will be "blue". I'm afraid that you
are wrong. Because the sky has no color. 
     What's in the sky? Is the sky full of (充满) air? I'm sure that you have asked these questions. We all
know that there is air around the world. We can not live without air. Planes can't fly very high because
as we go higher, the air gets thinner (更稀薄). If we go far enough away the earth, we can find that there
is no air. The sky is space (太空). In the space there is nothing but the sun, the moon and the stars.
       People always want to know more about other worlds in space. They have looked at them through
telescopes (望远镜) and in this way they have known much. They know a lot about the moon now. but
they want to know more about space. I'm sure they will go farther and farther until they know all about it.

     When you are learning a language, listening, speaking and writing are important,   but reading can  also
be very helpful. When you read,  you can not only learn some new words, but also learn how to use them. When you read a passage, it gives you a good example for writing. Here are some good reading tips.
     Firstly, try to read at the right level (水平). Read something that you can understand.  If it is too  hard
for you, it is not interesting.
     Secondly, try to understand the new words.  If there are four or five new words on a page,  don't  use
a dictionary.  Instead, try to guess their meanings as you read.   Mark (作标记) them with a pencil. Then
look them up in a dictionary when you finish reading,   and write them in your own vocabulary book.  Try
to remember them.
     Thirdly, try to read for a short time once a day. Fifteen minutes or half an hour every day is better than
two hours every Sunday.   For example,   you can read before you go to bed,   or after you get up  or  at
lunchtime.
     Lastly, read something that interests you. Choose a newspaper, a book or a magazine about a subject
that you like. It will be easy enough for you to understand.
