Water is very important to people. We must drink water every day. We can't live without(没有) water, Water is everywhere around(环绕) us. At home, we use water to wash clothes, to wash dishes, to cook meals, to clean our room, to have showers, to make drinks(饮料), to clean our teeth, to have a bath and so on.
At work, people use water to put out fires, to grow vegetables, to make things in factories and so on. They also can swim in the river. Water is important to us, isn't it?
However（然而) there isn't much water on the earth. It is very valuable（珍贵的）. We must save it. If we waste(浪费) too much water, one day in the future, the last drop(滴) of water on the earth will be our tea(眼泪).
