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. [br] What was brought to the rich and powerful country when it gained the empire by cutting down its trees to build warships?
选项 A、The country’s soil became solid and poor.
B、The country fell into pieces.
C、The country met with floods and famine.
D、All of the above.
答案 A
解析 本题是一道具体细节题。问当那个富裕强盛的国家砍光了树木建造战舰赢得了一个帝国之后的结果是什么。利用查阅式阅读法，根据第三段，2 000年前的某一富强国家砍伐树木、建造战舰，虽赢得了一个帝国，但没有树木后的结果是土地变得硬结、荒芜。B、C两选项中所讲的不是砍伐树木、建造战舰的直接后果。因此，本题的正确答案应是A。
