政府招商引资的前提仍然是（）。A、讲道德 B、讲原则 C、守信

Man has a big brain. He can think, learn and speak. Scientists thought that men are different from animals because they can think and learn. They know now that dogs, cats and birds can learn too. They are beginning to understand that. They make noises when they are afraid, or angry or unhappy. Apes(猿) can understand some things more quickly than human, one or two of them have learnt a few words. But they can not join words to make sentences. They can not think like us because they have no language. Language is a wonderful thing. Man has been able to build a modern world because he has language. 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 really know. What happens inside our body when we speak? They do not know. They only know that man can speak because he has a brain.
