Man has a big brain
（脑）. He can think, learn and speak. Scientists once thought that men are different from animals because they can think and learn. Now they know that dogs, cats and birds can learn, too. They are beginning to understand that men are different from animals because they can speak. But animals can't. They make noises when they are afraid, or unhappy. Apes（猿）can even understand some things more quickly than men. One or two of them have learned a few words. But they cannot join words to make sentences. They cannot think like us because they have no language. Language is a wonderful thing. With its help, men can make anything even our modem world. Every child can speak his own language very well when he is four or five, but no animal learns to speak. How does a child learn it? Scientists do not really know. They only know that man can speak because he has a brain.根据短文内容选择最佳答案。
