题目内容
Many animals have tails（尾巴）. They use their tails to do many different things.
Some animals use their tails as flyswatters（苍蝇拍）. Have you ever seen a cow shake its tail back and forth? It’s driving away the flies. Horses also use their tails in the same way.
Some animals hang by their tails. Monkeys often do this. Then they can use all four of their paws for other things, such as eating. Monkeys use their tails as a “hanger”, which can help them hang in the trees and climb trees. Animals that live in the water use their tails to help them swim. A fish uses its tail from side to side. A kangaroo has a large, useful tail. It’s like a chair. The kangaroo stands on its tail to rest. It helps the kangaroo stand well. The tail is also good for landing. This is important because an adult kangaroo can jump as far as 15 feet at a time. A fox has a big tail. This is a good tail to have on cold nights. The fox can put its tail over its nose and paws while it sleeps. The tail can keep the fox warm.
Some animals don’t keep their tails with them at all times. If their enemies（敌人） catch them, their tails will break off（折断）. Don’t worry. They will soon grow a new tail. How amazing（令人惊异的） it is!
