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 is the final result if trees are cut down ruthlessly?
选项
A、The roots of trees will break up the soil and bind the soil together.
B、The rainwater falls on the ground will wash away the soil.
C、The rainwater will lead to floods and carry away the rich top-soil.
D、The whole farmland will become a large area of poor, sand-covered land.
答案
D
解析
本题是一道具体细节题。问如果人们无情地砍伐树木,最终的结果将会如何。根据文章第五段内容,作者讲述了无情砍伐树木的危害,不仅将来人们的后代子孙所拥有的树木越来越少,而且会由于缺少树木而导致土壤流失,最终结果是使土地变成毫无价值的沙漠。因此,本题的正确答案应是D“最终农田会变成大面积的荒芜的沙漠”。
