高中英语语法-议论文精选（2）之二

　　　　If you do all these above， you will be strong and healthy.

　　　　Trees Are Important to Use

　　　　Trees are very useful to people. They provide us with wood and other products. They give us shade and they help to prevent drought and floods.

　　　　Unfortunately， in many parts of our country， people haven't realized the importance of trees. They cut them down at will. They are usually too lazy or too careless to plant and look after new trees. As a result， the forests continue to disappear.

　　　　Where there are no trees the rain falls on the surface， causing floods， and carries away with the rich topsoil， in which crops grow so well. When all the topsoil is gone， nothing remains but worthless deserted.

　　　　The big floods of 1998， in parts of China， have already taught us a good lesson. So every one of us must love trees， protect forests， and keep on planting trees each year.

　　　　Smoking and Health

　　　　Today cigarette smoking is a widespread habit all over the world. It was reported recently that smokers make up one quarter of the world population， while in China， 33.9 precent above the age of 15 are smokers. It's a very serious problem because not only the old， the youth， but also middle school students and girls have been engaged in smoking.
