这段文字怎么翻译？不要电脑翻译的。

Trees are useful to men in three important ways: they give them with wood and other products, they give them shade, and they help to prevent drought (干旱) and floods (水灾).
Unfortunately, in many parts of the world, men have not known that the third of these left trees are the most important. In their eagerness (渴望) of making money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had. And besides, they are usually too careless to plant and look after new trees, so the forests slowly become smaller and smaller.
This does not only mean that men will have fewer trees. The results are even more serious: for where there are trees, their roots(根)break up soil-allowing the rain to sink in-and also bind(固定)the soil, thus preventing it from being washed away easily, but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil (地表土). When all the top-soil is gone, nothing remains(剩下)but desert.

树对人类很重要，有以下三个方面：它为人类提供木材和其他产品，为人类提供树荫，还可以帮助人类预防干旱和水灾。
不幸的是，在世界上的许多地方，人们还不知道树给我们带来的三个好处是多么的重要。他们渴望从树上来赚钱，一些人砍去了大量的树却没发现没有了树，他们失去了他们最好的朋友。除此之外，他们经常粗心大意的种植和照料树，所以慢慢的，森林变的越来越小。
这不仅意味着人类将哟更少的树，更严重的后果是：有树的地方，树根可以使土壤松散，可以使雨水渗透，进而可以固定土壤，这样可以防止土壤被轻易的冲刷走，但是没有树的地方，雨水落在坚硬的土地上，流走，造成洪水，还带走大量的地表土。当所有的地表土都被冲走了，除了沙漠就沙漠也没有了。
