Answer 1

分析 本文屬于記敘文閱讀，主要向我們說(shuō)明了北美洲的保護(hù)組織一直在爭(zhēng)論狼的利益和危險(xiǎn)，一些組織認(rèn)為狼應(yīng)該被殺，而另一些人說(shuō)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 DGABF
31  D  根據(jù)后文so that they will not disappear from the wilderness（荒野）．  可知他們不會(huì)從荒野消失，所以必須保護(hù)它們，故選D．
32  G  根據(jù)后文So the wolf population has greatly increased． 可知狼的數(shù)量快速增加的原因是制定法律保護(hù)狼，故選G．
33  A  根據(jù)后文We'd also save some farm animals． 可知我們還可以拯救農(nóng)場(chǎng)動(dòng)物，因此此處應(yīng)該填我們可以拯救他們和獵物，故選A．
34  B  根據(jù)前文The wolves keep the deer population from becoming too large，可知狼可以阻止鹿數(shù)量的快速增加，后句和前句的句式結(jié)構(gòu)是一致的，故選B．
35  F  根據(jù)后文Even if wilderness land is not used directly for human needs，the wolves can't always find enough food．可知即使荒地沒(méi)有被直接被人類(lèi)使用，狼也不能找到足夠多的食物，因此此處應(yīng)該填狼生活的地方被人類(lèi)使用，故選F．

點(diǎn)評(píng) 做七選五題目時(shí)要注意以下規(guī)則：1．放進(jìn)去通順，這一點(diǎn)是基礎(chǔ)．凡不通順的必錯(cuò)無(wú)疑；2、選項(xiàng)中有單詞、詞組、句子成分或與所選答案所在段內(nèi)容重合；
3、選項(xiàng)與其上句或下句之間有必然的邏輯關(guān)系；4、選項(xiàng)全部?jī)?nèi)容都屬于正確答案所在段．有時(shí)備選答案中可能含有甲乙兩項(xiàng)內(nèi)容，這時(shí)，只有當(dāng)甲和乙都?xì)w屬于本段時(shí)，答案才是正確的．
