Question

【題目】根據(jù)短文理解，選擇正確答案。
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(獵物) 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】本文是一篇議論文，北美洲的人一直在爭論狼對(duì)自然和人類的好處與壞處。文章從正反兩方面對(duì)這一問題進(jìn)行了論述。

⑴細(xì)節(jié)理解。根據(jù)第二段倒數(shù)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(獵物) 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三項(xiàng)都是人們支持殺狼的原因。而D項(xiàng)不是。

⑵推理判斷。根據(jù)文章倒數(shù)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，狼只會(huì)捕殺弱小的、多病的動(dòng)物，那些強(qiáng)壯的動(dòng)物個(gè)體會(huì)生存下來。這有利于動(dòng)物種群的延續(xù)，同時(shí)這也是自然法則。也就是說狼實(shí)際上是在幫助這種動(dòng)物在自然界中生存下來。故C項(xiàng)正確。

⑶句意理解。根據(jù)文章倒數(shù)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，當(dāng)大自然不能給狼提供足夠的食物時(shí)，它們就會(huì)擴(kuò)大獲取食物的范圍，進(jìn)而攻擊人類；而當(dāng)人類受到威脅后，也會(huì)攻擊狼群。故最后一句和B項(xiàng)語義一致。
