We see many animals, like rabbits(兔子), bees, dogs, birds, sheep……but do you know how these animals say things? First, let's see a rabbit. When a rabbit sees something dangerous, it runs away at once. When it runs, its tail(尾巴) moves up and down. When others see this, they run too.
Many other animals use this kind of language. When a bee has found some food, it goes back to its home. It cannot tell other bees where the food is by speaking to them, but it does a little dance in the air. This may tell other bees where the food is.
Some animals say things by making sounds like a man does. For example, a dog barks(吠) when a stranger(陌生人) comes near. Some birds can make several different sounds, each with its own meaning. In a word, every animal has its own language.
