8．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 wilderndss（荒野）
For Killing Wolves
In Alaska，the wolf almost disappeared a few years ago，because hunters were killing hundreds 0f them forsport．However．1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur．So the woIf 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 woIf 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 woIf'"will not disappear．
But the fact is wolves are afraid of people．a(chǎn)nd 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 bv 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．

分析 本文屬于記敘文閱讀，主要向我們說明了北美洲的保護(hù)組織一直在爭論狼的利益和危險，一些組織認(rèn)為狼應(yīng)該被殺，而另一些人說出了狼存在的好處，文章中介紹了這兩種不同觀點(diǎn)的理由，告訴我們其實(shí)狼在自然界中有很大的用處．
解答 60．D 細(xì)節(jié)理解題，根據(jù)第四段So the woIf population has greatly increased．If the wolves continue to kill large numbers of deer，their prey（獵物）will disappear some day．In another northern state，wolves attack cows and chickens for food．可知獵殺狼的原因是因?yàn)橛刑嗟睦牵麄儦⑺来罅康穆共⒐裟膛＃鴽]有提到他們破壞曠野植物，故選D．
6l．A 細(xì)節(jié)理解題，根據(jù)倒數(shù)第二段The wolves keep the deer population from becoming too large，and that keeps a balance in the wilderness plant life．可知一些人反對殺狼是因?yàn)槔窃跁缫爸袔椭３稚鷳B(tài)平衡，故選A．
62．C 細(xì)節(jié)理解題，根據(jù)倒數(shù)第二段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．可知狼吃那些年輕的生病的或受傷的動物，體現(xiàn)了適者生存的自然法則，因此狼可能幫助這種動物在大自然中生存，故選C．
63．B 推理判斷題，根據(jù)最后一段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．可知如果狼的居住的地方被人類占據(jù)，它們不能獲得足夠的食物，就會跑到就近的農(nóng)場吃人，那么人類也會反過來殺死它們，故選B．
點(diǎn)評 做閱讀理解時要快速的瀏覽全文，把握文章主旨大意，帶著問題回到原文，尋找細(xì)節(jié)或概括相應(yīng)的答案，最后要理清作者寫作思路．
