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 and so on.

    At work, people use water to put out fires, to grow vegetables, to make things in factories and so on. We can also swim in the water.

    However, there isn't much water on the earth. We must save it.
