阅读理解。 Animals, including insects, do not have a language like ours. They do not talk to each other in words and sentences. But if we watch them, we can see that they do have ways of communicating with each other. Can you see the rabbit's tail which is moving up and down? When rabbits see this white tail moving up and down, they run too. They know that there is danger. The rabbit has told them something without making a sound. It has done this by using its body language. Many other animals use this kind of language. When a cobra is angry, it raises its head 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 sounds. 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. But we have something that no animals have-a large number of words that have the meanings of things, actions, feelings or ideas. We are able to give each other all kinds of different information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have. 1.
