     Animals, including insects, don't 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 their ways of communicating with each

other.

     Can you see the rabbit's tail? When rabbits see this white tail moving up and down, theyrun away. They

know that they are in danger. The rabbit has told them something without making a sound. It has given

them a signal.

     Many other animals use this kind of "language". When a cobra(眼镜蛇) is angry, it raises its head and

makes itself look fierce. This worns other animals. When a bee has found food, it. goes back to its home.

It cannot " tell" the other bees where the food is by speaking tothem, but it does a little dance. This tells the bees where the food is.

    Some animals "say" things by making sounds. A dog barks, for example, when a stranger comes near, A

cat purrs(发出呼噜声) when it is pleased. Some birds make several different sounds, each with its own

meaning. Sometimes we human beings speak in the same way. We make a sound like "Oh" or "Ah" when

we are frightened or pleased or when we drop something on our toes.
