　　组织同学们到图书馆查找关于国外植树造林或保护环境的资料，然后分组整理出关于这方面的英语文章，要有一定的说服力，并且内容真实严谨。是一篇完整的语篇，上下文连接要紧密，并说明一定的道理，有教育意义。

　　In developing countries people mostly use wood for cooking and heating. They cut down trees for fuel. But a tree cools the land under it and keeps the sun from smaller plants. As the leaves fall, they enrich the soil. When trees disappear, smaller plants die and only sand remains. Yet people need fuel, animals, and crops in order to live.

　　Men can take deserts, but they can also prevent them from getting bigger. Algeria(阿尔及利亚) is planting a green belt of trees along the edge of the Sahara Desert(撒哈沙漠) to stop the sand. In China, too, windbreaks(防风林带) are being built in the northwest to keep the desert from growing.

　　But deserts still threaten the world. Experts believe that land that is on the way to becoming

　　desert equals the size of Australia, Russia and the United States put together. Can we stop the spread of the world's deserts and save the land that is so essential to mankind? Yes, we can. And we must.

　　【范文】Knowledge

　　Knowledge is to us what a compass is to a ship.  A ship has to rely on a compass to sail safely across an unknown ocean. Similarly, knowledge brings forth power we need to make real progress toward a better life.  With knowledge, we can invent new and useful apparatus and  machines; we can create beautiful art, including paintings, sculpture, music, and so forth; we can make clothes, furniture, cars, space shuttles and the like.  It is knowledge that enables us humans to lead a convenient and colorful life.  On the contrary, were it not for knowledge, people would become stupid and uncivilized; everything would get back to the primitive age; no more human history could be passed down.  In short, the more knowledge we gain, the wiser we will become.
