Trees are useful to man in three very important ways: they provide him wood and other products, they give him shaded and they help to prevent drought and floods.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that with them he has lost the friends he had.
Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the home country found itself faced by floods and starvation.
Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. (80)
So, unless the government has a good system of control, or can educate the people, the forests slowly disappear.
This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are on trees, the rain falls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich topsoil in which crops grow. When all the topsoil is gone, nothing remains but worthless desert.
选项
A、keep him from the hot sunshine
B、prevent him from floods
C、make him draw quick profit from them
D、help him to keep from the attack of drought and floods
答案

解析
