25、第二句可以推知,人们有必要保护环境的原因是许多动物正濒临灭绝,故答案为B项。4.B根据第二段中的“Aspartofaclassproject,MyersstudentsboughtthreeacresofrainforestinCentralAmerica.Theypaid$25peracre.”可知他们买了三英亩,单价是25美元,因此选B项。5.C根据第三段中的“SolastJune,Myersandfourofhisstudentstookaboatridedownariver.”可知选C项。6.A句意:世界上热带雨林的破坏是一个严重的问题。由画线词后面的aseriousproblem和d
26、isappearing等词可推知此处应是消极词汇。故选A项。7.A通读文章尤其是第二段可知,本文主要讲述了Myers和他的学生做了一些事情来保护热带雨林。因此选A项。五、1.B由第一段的alazycrow和Ifsomeonebroughtmemyfoodeveryday可推知它认为寻找食物太麻烦而不愿自己觅食。故选B项。2.C句意:如果有人每天给我送食物,我会非常高兴。由前文的lazy可推知乌鸦此处的情感应是高兴。3.D由第二段的Howhappyandwell-feditlooks中的well-fed(喂养得很好)可得出这只鸽子是丰满的。故选D项。4.A此处表示乌鸦“跟着”鸽子来到了一个“公园
27、”,第四段的heflewofftothepark也有提示。5.C在国外,鸽子一般都会成群结队地在公园出现,让游客或行人进行喂养。第四段的tothepark也是提示。故选C项。6.C此处表示在那儿也有一些“鸽子”,由too可知应是词义复现。7.B由常识可推知,乌鸦看到了有人送食物就想“加入”鸽子群和它们一起分享食物。8.C由下文的angrily可知此处表示鸽子向乌鸦生气地大声“喊叫”。9.D鸽子群不让它加入,乌鸦因而感到“悲伤”,第五段开头的Sadly也是提示。10.A由后面它说的话可知,此处表示它突然有了一个“想法”。11.B由最后一段的最后一句话“IwishIhadneverpaintedm
28、yfeathersgrey!”可知此处应选B项。12.D乌鸦认为将羽毛涂成了和鸽子羽毛一样的颜色,那么鸽子就会“认为”自己是同类。13.A由空后的“Thecrowwassohungrythathegotveryexcitedatthefood.”可以看出它被鸽子群接受了,故选A项。14.C由前面乌鸦的叫声可推知,此处表示鸽子们“突然”发现它是一只乌鸦。15.D由前面的flewafterhim可推知,此处表示它们让乌鸦“离开”。16.A此处表示当它的同类看到它的时候也让它离开。goaway和上空的leave同义。17.C由空后的becauseofhisgrey-paintedfeathers可知,它的羽毛颜色没有恢复成原来的样子,因而它没被它的朋友认出来。故选C项。18.B由语境可知,乌鸦被两方驱赶,所以此处表示乌鸦感觉比以前还要“糟糕”。19.B根据上文的“Butwhenhisoldfriends,theothercrowssawhim.”可知此空选B项。20.D它的老朋友不要它,它也无法回到鸽子群里,这应该是并列关系。故选D项。
