　　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 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 much farther away than the moon. One day rockets may be able to go to any place in space.

　　Man has a big brain（大脑）. He can think, learn and speak. Scientists once thought that men are different from animals because they can think and learn. They know now that dogs, rats and birds can learn, too. They are beginning to understand that men are different from animals because they can speak. Apes（类人猿）can understand some things more quickly than man, one or two of them have learnt a few words. But they cannot make sentences with words. They cannot think like us because they have no language. Language is a wonderful thing. Man can make our world more beautiful because he has languages. Every child can speak his own language very well when he is four or five, but no animal learns to speak. How do children learn it? Scientists do not know. What makes us speak? They do not know. They only know that man can speak because he has a brain. Animals cannot speak. They make noises when they are afraid, or angry or unhappy.
