Question

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，laws 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.That 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

解析;細節理解題。從For Killing Wolves部分看出：第一段最后一句說明狼多是獵狼的原因之一，A項正確；第二段和第三段說明狼殺死大量的鹿是獵狼的原因之一，B項正確；第四段說明狼襲擊農民的牛和雞是獵狼的原因之一，C項正確。由此可知答案為D項，文章沒有說明作為食肉動物的狼對野生植物的破壞程度。

答案;D

解析;細節理解題。從Against Killing Wolves部分的第二段和第三段看出，狼獵食其他動物，使其他動物優勝劣汰、適者生存，符合自然界的法則；并且研究表明狼和鹿等其獵物數量保持平衡，避免了鹿群過度膨脹，也保護了野生植物的平衡，因此答案為A項。

答案;A

解析;細節理解題。根據Against Killing Wolves部分的第二段第二句可知，狼通常吃幼小和有病的動物，但不是從來不吃，故A項錯誤；由這部分第二段最后一句可知，B項錯誤；由此部分第三段最后一句可知，D項錯誤；由此部分第二段可知，狼獵食其他動物使它們優勝劣汰，并長期生存下去，故C項正確。

答案;C

解析;推理判斷題。從文章的最后一段看出，狼生存的環境遭到人為破壞，找不到足夠的食物，就會來到農場等地方覓食，“狼來了”帶來的結果必然是“人狼互相殘殺”。

答案;B
