Question

【题目】根据短文理解，选择正确答案。
It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野).
For Killing Wolves
In Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life．When the deer can't find enough food，they die.
If the wolves continue to kill large numbers of deer, their prey(猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We'd also save some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population．
Against Killing Wolves
If you had lived long ago，you would have heard many different stories about the dangerous wolf．According to most stories，hungry wolves often kill people for food．Even today，the stories of the “big bad wolf” will not disappear．
But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell．When wolves eat other animals，they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.
Although some people say it is good sense to kill wolves，we say it is nonsense! Researchers have found wolves and their prey living in balance．The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.
The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can't always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The “big bad wolf” has arrived! And everyone knows what happens next.

Answer 1

【答案】
（1）D
（2）C
（3）B
【解析】本文是一篇议论文，北美洲的人一直在争论狼对自然和人类的好处与坏处。文章从正反两方面对这一问题进行了论述。

⑴细节理解。根据第二段倒数第二句So the wolf population has greatly increased.第三段第一句If the wolves continue to kill large numbers of deer，their prey(猎物) will disappear some day.和第四段第一句In another northern state，wolves attack cows and chickens for food．可知，ABC三项都是人们支持杀狼的原因。而D项不是。

⑵推理判断。根据文章倒数第三段When wolves eat other animals, they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.可知，狼只会捕杀弱小的、多病的动物，那些强壮的动物个体会生存下来。这有利于动物种群的延续，同时这也是自然法则。也就是说狼实际上是在帮助这种动物在自然界中生存下来。故C项正确。

⑶句意理解。根据文章倒数2、3句Even if wilderness land is not used directly for human needs．the wolves can't always find enough food .So they travel to the nearest source, which is often a farm．Then there is danger可知，当大自然不能给狼提供足够的食物时，它们就会扩大获取食物的范围，进而攻击人类；而当人类受到威胁后，也会攻击狼群。故最后一句和B项语义一致。
