Forests have always been useful and important to men who make use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from the terrible heat. They’re also useful in preventing(阻止) good and rich top soil from being washed away during heavy rains. If there were no forests, heavy rains would wash away the rich surface(表层) soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but men in the past had no enough knowledge about science of nature, and they cut down too many trees in the area where they lived and never planted new ones. By and by, the rich surface soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.

In most parts of the world, many students help their school make less pollution. They join in “environment clubs”. In an environment club, people work together to make our environment clean.
Here are things students often do：
Turn off the water! Do you know that some toilets can waste twenty to
forty tons of water an hour? In a year, that would fill a small water! In environment clubs, students mend those broken toilets.
No-car day. On a no-car day, nobody comes to school in a car-not the students and not the teachers. Cars give pollution to our air, so remember: walk, jump, bike or run.
Use your legs! It’s lots of fun!
No-garbage(垃圾) lunches. How much do you throw away after lunch?
Environment clubs ask students to bring their lunches in bags that can be used
again. Every week they will choose the classes that make the least garbage
and report them to the whole school.
