问题     Trees are useful to man in three very important ways: they provide him with wood and other products; they give him shade; 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.
    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 hard and barren (贫瘠的,荒芜的). When the empire collapsed, 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 for it to persuade the villager to see this. The villager wants wood to cook his food with; and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after new trees. So, unless the government has a stern system of control, or can educate the people, the forests will slowly disappear.
    This does not only mean that the villagers’ sons and grandsons have 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, thus preventing its being washed away easily, but where there are no trees, the rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich top-soil, in which crops grow so well. When all the top-soil is gone, nothing remains but worthless desert.
What actions can be taken to prevent people from cutting down trees?

选项 A、To persuade the villagers to understand the importance of trees.
B、To provide the villagers with more money and food.
C、To set up a strict system of control and educate the people.
D、To ask the villagers not to be lazy or careless.

答案C
