We know the air is very important for us. Without air, we couldn't live. Other creatures can't live either. We need clean air. The dirty air is bad for us. Now the air pollution is very serious in some places. For example, the smoke from some factories make the air dirty. Exhaust gas from cars make the air dirty. The forest fire can make the air dirty, too. So we need to pay attention to the air pollution. We can plant more trees and think of other ways to sovle the problem.

    Elephants are mammals. They can be four metres tall. They don't eat meat. They only eat fruit, leaves and grass. They need a lot of food, so they spend most of their time eating. They only sleep for about four hours every night.

    The elephant has two long, white teeth called tusks. It is the only animal with a trunk-a special long nose. The elephant can use its trunk to pick up big tree or a small peanut. The elephant is also the mammal with the biggest ears. They look like two big fans.

    Elephants live in Africa and Asia. They live together in family groups. They are very strong, very smart and of course, very, very big.
