Animals can not speak. They make noises when they are afraid, or angry or unhappy. Apes
(类人猿) can understand some things more quickly than men. One or two of them have learnt a few
words. But they can not put words together to make sentences. They cannot think as we do because
they have no languages. The language is a wonderful thing. Man is able to build a modern world
because he has language.
Each 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 don't know. They only know that man can speak because
he has the brain.
