gical. B．Interesting.C．Short-term. D．Damaging.解析：選D詞義猜測題。根據(jù)后文可知，棕樹蛇吃鳥，島上曾經(jīng)有12種鳥類，但是這些蛇已經(jīng)殺死了九種鳥類。蛇可以長到10英尺長，它們經(jīng)常咬人。它們爬上電線，讓電力供應中斷，這造成了數(shù)百萬美元的損失。以上說明了這種蛇的危害性很大。由此可以推斷出畫線詞devastating意思是“有破壞性的”。故選D項。7．Whatwasamoreworkablewaytokillthebrowntreesnakes?A．Usingsnaketraps.B．PuttingTylenolinthetrees.C．Bringingintheirenemies.D．LettingthemeatTylenolcarriedbymice.解析：選D細節(jié)理解題。根據(jù)第四至六段內(nèi)容可知，殺死棕樹蛇的一個有效方法是讓它們吃攜帶Tylenol的老鼠。8．WhatdoesMrVicethinkofsolvingthissnakeproblem?A．Heisproudofit.B．Heishopefulofit.C．Heisdoubtfulaboutit.D．Heisunconcernedaboutit.解析：選B推理判斷題。根據(jù)最后一段中Guam島農(nóng)業(yè)部的Vice先生說：“這不應該阻止島民的嘗試。我們的長期目標是徹底消滅蛇?！笨赏茢喑觯琕ice先生對解決蛇的問題滿懷希望。CAsmallinsectisgettingalotofattentionintheUnitedStates.Therustypatchedbumblebee(大黃蜂)isthefirstofitsspeciestobedeclaredendangeredinthelower48states—meaningeverystateexceptAlaskaandHawaii.Therustypatchedbumblebeeisnamedforarust-coloredlineonitsback.TheUSFishandWildlifeServiceannouncedthismonthitwasaddingthebeetoitsendangeredspecieslist.Theinsectsare“onthebrinkofextinction”，accordingtotheservice.Itsaidthebeeswereoncefoundin28states.Buttherenowareonlysmallpopulationsremainingin13states.Thegovernmentagencywillmakeaplantohelpthedyingbeesrecover.Theagencysaidthatsuchaplanmighthelpotherinsects,likebutterflies.USofficialsthinklandownerscantakesmallstepstohelptherustypatchedbumblebee.Theysaylandownerscanbefriendliertowardsbeesbyusingnativeplantsintheirgardens.Theinsectsdirectlyfertilizemanykindsoffruitandvegetablecrops.Andtheyfertilizegraincropsusedtofeedcattleandmilkcows.Itcostsbillionsofdollarstoduplicatethejobthebeesdoforfree.Landownersarealsobeingurgedtocutbackontheiruseofpesticideproducts.Theofficialsalsosuggestthatgardenersleavetheirplantsaloneattheendofthesummerinsteadofcuttingthem.Thatway,thebeeswillhaveaplacetoliveoverthewinter.TheFishandWildlifeServicesaystherustypatchedbumblebeewasaddedtotheendangeredspecieslistpartlybecauseofhabitatloss.Otherreasonsweredisease,pesticidesandclimatechange.Officialsareworriedthatotherbeeswillsuffer,too.AnotherspeciesofbeesinHawaiiisalsoendangered.語篇解讀：本文是一篇說明文。文章介紹了在美國瀕臨滅絕的銹跡大黃蜂的相關信息。9．Howmanystatesdeclaredtherustypatchedbumblebeeendangered?A．13. B．28.C．48.D．50.解析：選C細節(jié)理解題。根據(jù)第一段中Therustypatchedbumblebee(大黃蜂)isthefirstofitsspeciestobedeclaredendangeredinthelower48states—meaningeverystateexceptAlaskaandHawaii.可知，銹跡大黃蜂是48個州中第一個被宣布瀕臨滅絕的物種，這意味著除了阿拉斯加和夏威夷以外的每一個州都是如此。由此可知，有48個州宣布銹跡大黃蜂瀕臨滅絕。10．Whichoneisharmfultotherustypatchedbumblebee?A．Plantingnativeplants.B．Reducingtheuseofpesticideproducts.C．Leavingplantsalone.D．Cuttingoutplantsregularly.解析：選D推理判斷題。根據(jù)第三段中最后一句Theofficialsalsosuggestthatgardenersleavetheirplantsaloneattheendofthesummerinsteadofcuttingthem.Thatway,thebeeswillhaveaplacetoliveoverthewinter.可知，官員們還建議園丁們在夏末的時候不要去修剪植物，而是讓它們自己生長。這樣，蜜蜂就有地方過冬了。由此可以推斷出，定期剪植物對銹跡大黃蜂是有害的。11．Whatcanweknowabouttherustypatchedbumblebeeaccordingtothetext?A．Allthestatesdeclareditasendangeredspecies.B．Itisnamedforarust-coloredlineonitsbelly.C．Itisbeneficialtolandowners.D．Itisendangeredmainlybecauseofhabitatloss.解析：選C推理判斷題。根據(jù)第三段中Theinsectsdirectlyfertilizemanykindsoffruitandvegetablecrops.Andtheyfertilizegraincropsusedtofeedcattleandmilkcows.Itcostsbillionsofdollarstoduplicatethejobthebeesdoforfree.可知，這些昆蟲直接給許多水果和蔬菜作物施肥，它們還為喂牛和奶牛的谷物施肥，而復制蜜蜂做的這些免費的工作要花費數(shù)十億美元。由此推知，銹跡大黃蜂對土地的主人是有益的。12．What'sthebesttitleforthepassage?A．BumblebeeAddedtoUSEndangeredSpeciesListB．WhyIsBumblebeeontheBrinkofExtinctionC．TakeStepstoHelpBumblebeeD．TheBenefitsofProtectingBumblebee解析：選A標題歸納題。根據(jù)最后一段第一句TheFishandWildlifeServicesaystherustypatchedbumblebeewasaddedtotheendangeredspecieslistpartlybecauseofhabitatloss.可知，魚類和野生動物管理局說銹跡大黃蜂被列入瀕危物種名單，部分原因是棲息地喪失。由此可知，A項(大黃蜂加入了美國瀕危物種名單)適合作本文標題。Ⅱ.閱讀七選五Ifyourfamilyisthinkingofgettingapet,consideradoptingfromananimalshelter,whereallanimalsareinneedoflovinghomes.1Herearesometipsforyoutofindgreatanimals.Makesomedecisions.Thinkaboutwhatyouwantinapetandrememberthatallpetshavedifferentpersonalities.Catstendtobemoreindependent,butkittensneedlotsofattention.2However,theyareusuallygreatcompanionsandlovetospendtimewiththeirfamily.Visittheshelter.3Rememberthatyoumayneedtovisitmorethanoneshelter,oryoumayneedtomakemorethanonevisit.Trytobringalongeveryonewhowillbelivingwiththenewpet.Asktheshelterstafflotsofquestions.Andneveradoptananimalbecauseyoufeelsorryforit—bepatientsoyoucanfindapetwhoistrulyagoodmatchforyourfamily.4Buyallnecessarysuppliesandfoodwellbeforetheanimalcomeshome.Makesurethattheentirehouseholdisinagreementaboutrulesandresponsibilities—willthedogbeallowedonthecouch?Whowillcleanthelitter-box?Putitinwritingbeforethepetarrives.Bringyournewfriendhome!You'llprobablybeexcitedw
