Animals are our friends. We can find different kinds of animals. Some animals are living in big woods(树林). And some animals are living with man. Why? Because they can work for us. People can teach the elephant to do some heavy work.
And they can also teach the dog to look after the house. A dog is very clever. It can help people in danger(处于危险中). Children like dogs very much. Most children
like to go to the zoo, because there are many animals in the zoo. A zoo is a good place for children to get to know animals.
