Trees are very useful to human beings. They can give ue shade and make the air clean and fresh. Wood comes from trees. Many things in our life are made of wood. In recent years, several big floods happened in some areas in our country. One of the reasons is that there are not enough trees in the areas. Trees can protect soil from being destroyed.
But in many parts of our country, some people haven't realized it. They don't take care of trees after they plant them, or they don't plant trees at all. Even worse, some people just think about getting something from trees, but not giving something to trees. They keep cutting, cutting and cutting.
There will be only one result. At last we will find we are living in a desert.
I hope more and more people plant more and more trees.
( 树对人类很有用，它们给我们提供树荫，而且还使空气清新。木头来自于树，我们生活中很多东西都是由木头制成的。近年来，我国的一些地方发生了大洪水，一个重要的原因就在于那儿没有足够多的树，树木可以保护土壤不被破坏。
但在我国的许多地方，一些人并没有意识到这一点。他们种树后就不照看它们了，或者他们就不种树。更糟的是，人们只想着向树索取，却不想给予树些什么。他们不停的砍呀，砍呀，砍呀。
那样就只有一个结果：最终我们发现自己生活在沙漠中。
我希望越来越多的人来种越来越多的树。）
