　　Water is very important to people. We must drink water every day. We can't live without water. Water is everywhere around us. At home, we use water to wash clothes, to wash dishes, to cook meals, to clean the flat, to have showers, to make drinks, 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. We also can swim on the earth. Water is important to us, isn't it?
