12、elds”可知,作者首先用拖拉机把荒地变成了(changed)良田,以便耕种。2.A.ThereforeB.HoweverC.OtherwiseD.Besides答案B解析根据语意可知,此处表示转折关系,因为接下来介绍浣熊破坏了庄稼,所以选B项。3.A.winterB.saleC.sowingD.harvest答案D解析根据句中的“largeamountsofcornwereeaten”可知,浣熊应该是在收获的(harvest)季节破坏庄稼,吃掉大量的玉米。4.A.break awayB.run awayC.jump upD.turn up答案B解析根据下文描述的浣熊妈妈给孩子舔伤口的情节可知

13、,在作者走近时,浣熊妈妈为了保护幼崽并没有跑开(runaway)。5.A.handingB.takingC.standingD.reaching答案D解析作者伸出(reaching)手,设法给小浣熊松开夹子。6.A.tailB.neckC.teethD.mouth答案C解析根据常识和下文的“andgotreallyupset”可知,小浣熊看到有人靠近,会很不安,因此露出牙齿(teeth)。7.A.asB.becauseC.unlessD.after答案A解析看到小浣能的举动,为了防止被咬伤,作者给它松开夹子时(as),只好用胶靴压住它的头。8.A.woundedB.abandonedC.des

20、蜂方法及感悟。1.activities考查名词。other修饰可数名词复数,故填activities。2.which/that考查定语从句。分析句子结构可知,此处引导限制性定语从句,修饰chemicals,先行词为chemicals,从句中缺主语,故填关系代词which/that。3.lost考查动词时态。根据时间状语“Lastwinter”可知,事情发生在过去,应用一般过去时,故填lost。4.a考查冠词。此处修饰可数名词beekeeper,表示泛指“一位养蜂人”,作Thiele的同位语,且beekeeper以辅音音素开头,故填不定冠词a。5.are考查动词时态和主谓一致。此处陈述的是客观事

21、实,用一般现在时;主语为theusualways,谓语动词用复数,故填are。6.traditional考查形容词。此处修饰名词beekeepers,故填形容词traditional。7.with考查介词。分析句子结构和句意可知,此处应用介词,表示“用”,故填with。8.deeply考查副词。此处修饰动词belong,故填副词deeply。9.tokeep考查动词。此处为Itis+adj.+todosth结构,表示“做某事是的”,it为形式主语,后面的不定式是真正的主语,故填tokeep。10.further考查比较级。根据句意可知,此处有一个隐晦的比较意义,表示“进一步说”,故填furth
