Threes are useful to man in three very important ways:they provide him wood and other products;they give him shade;and they help to prevent drought (干旱) and floods.
Unfortunately, in many parts of the world, man bas 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.
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 pieced, the 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. 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 no 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.
Sooner or later the forests will disappear________.
选项
A、unless a country has a plenty supply of trees
B、unless people stop cutting down their trees
C、unless all people are taught the importance of planting trees
D、unless the government punishes those who cut trees instead of planting them
答案
C
解析
细节题。原文第四段最后一句话说除非政府加以有效控制或教育人民,森林才不会消失,也就是说当所有人都了解树的重要性,不乱砍滥伐,森林才不会消失,因此选项C是正确的;选项A说除非这个国家树木充足,与原文不符,树木再多,光砍不种也会砍光;选项B“除非所有人都不砍树”和选项D“除非政府惩罚那些砍树而不是种树的人”也与原文不符,并不是要不砍树,而是要砍种结合。
