Animals can help us a lot. Elephants can do some heavy work for us. And dogs can look after the home. The kids like dogs very much. Cats are women's favorite animals.

We can eat their meat. We can make coats and shoes with their skins(皮). We can get milk from them. So man can't live without animals.

    If you want to know how to swim, you must get into the river. And if you want to be a football player, you must play football.

    So, you see, you can learn by using it. You must listen to your teacher in class. You must speak English to your classmates every day and also you must write something in English. Then one day you may find your English very good.
