Question

Trees are useful to men in three important ways. They provide(提供)them with Wood and other products，they give them shade，and they help to prevent drought and floods.

Unfortunately，in many parts of the world，men have not realized that the third of these services is the most important. In their eagerness to make money from trees，some people have cut trees down in large numbers，only to find that they have lost the best friends they had. And besides，they are usually too careless to plant and look after new trees，so the forest slowly disappear.

This doesn't only mean that men will have fewer trees. The results are even more serious，for where there arc 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. When all the top-soil is gone，nothing remains but worthless desert.
