Man has a big brain(脑子). He can think, learn and speak. Scientists (科学家) once thought that man is different from animals because he can think and learn. They now know that dogs, rats and birds can learn too. They are beginning to understand that man is different from animals because he can speak. Animals can not speak. They make noises when they are afraid or unhappy. Apes(类人猿) can understand something more quickly than man. One or two of them have learned a few words. But they cannot put them together to make sentences. They cannot think like us because they have no language.

Language is a wonderful thing. Man can build a modern world because he has language.
