问题    Man has a big brain. He can think, learn and speak. Scientists used to think that man are different from animals because they can think and learn. They know now that animals--dogs, rats and birds--can learn. So scientists are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or hungry. or unhappy. Apes are our nearest cousins. They can understand some things mole quickly than human beings, and one or two have learned a few words. But they are still different from us. They cannot join words and make sentences. They cannot think like us because they have no language. They can never think about the past or the future. Language is a wonderful thing. Man has been able to develop civilization because he has language. Every child can. speak his own language vet well when he is four or five--but no animal learns to speak. How do children learn? Scientists do not really know. What happens when we speak? Scientists do not know. They only know that man can speak because he has a big brain.
