So far, many man-made satellites have up into space.——青夏教育精英家教网—

判断对错

　　When we talk about the universe，we mean the earth，the sun，the moon and the stars，and the space between them．Many of the stars cannot be seen because they are too far away．

　　The moon travels round the earth．It is our satellite．It is quite near us in space．It is only 380，000 kilometres away，and it has been visited by man already．So far，no man has travelled farther than the moon，but spaceships without people have reached other parts of the universe(宇宙)．

　　Man-made satellites(卫星) have been sent up into space by many countries．These satellites go round the earth and help us to learn more about the earth，the weather and other things．Most countries use these satellites to send and receive messages．For example，with their help China can send its TV and radio programmes to the other side of the world．Foreign countries can send their programmes to China．We can also use satellites to help us make telephone calls to foreign countries．

　　Our knowledge of the universe is growing all the time．Our knowledge grows and the universe develops．Thanks to space satellites，the world itself is becoming a much smaller place and people from different countries now understand each other better．

(1)

Many of the stars in space cannot be seen because they are too small．

     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.
