       Animals, including insects, do not have a language like ours. They do not talk to each other in words

or sentences. But if we watch them, we can see that they do have ways of communicating.

       Can you see the rabbits' tail. When rabbits see this white tail moving up and down, they are warning

each other to run. They know that there is danger. The rabbit has told them something without making

many other animals use this kind of language. When a cobra is angry, it raises its sound. It has given them

a signal and makes itself look fierce. This warns other animals. When a bee has found some food, it goes

back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little

dance in the air. This tells the bees where the food is. Some animals say things by making sound. A dog

barks, for example when a stranger comes near. A cat purrs when pleased. Some birds make several

different sounds, each with its own meaning.

       Sometimes we human beings speak in the same way. We make sounds like " Oh" or " Ah!" when we are frightened or pleased or when we drop something on our toes. Of things, actions, feelings or ideas, we are able to give each other all kinds of different. But we have something that no animals have a large

number of words which have the meanings, information in words and sentences, which no other animals

can do. No other animals have so wonderful a language as we have.
