三、阅读理解。
As we all know, the earth is a blue planet. There are a lot of rivers, lakes and oceans on it. Most of the water on the earth is sea water or ice. People can only use about one percent of the water on the earth. But today some people pollute(污染) or waste plenty of water. Therefore, there is not enough fresh water on the earth. So we must save water. Then what can we do to save water?
First of all, we can make a poster about saving water. It can let people know that water is very important. Saving water is good for them. Then we can begin with the little things around us. For example, we can use a glass of water to brush our teeth. We should take a quick shower as well. In a word(总之), water is very valuable. We should save every drop of water in our daily life.
