B．Interesting.C．Short­term. D．Damaging.解析：选D词义猜测题。根据后文可知，棕树蛇吃鸟，岛上曾经有12种鸟类，但是这些蛇已经杀死了九种鸟类。蛇可以长到10英尺长，它们经常咬人。它们爬上电线，让电力供应中断，这造成了数百万美元的损失。以上说明了这种蛇的危害性很大。由此可以推断出画线词devastating意思是“有破坏性的”。故选D项。7．Whatwasamoreworkablewaytokillthebrowntreesnakes?A．Usingsnaketraps.B．PuttingTylenolinthetrees.C．Bringingintheirenemies.D．LettingthemeatTylenolcarriedbymice.解析：选D细节理解题。根据第四至六段内容可知，杀死棕树蛇的一个有效方法是让它们吃携带Tylenol的老鼠。8．WhatdoesMrVicethinkofsolvingthissnakeproblem?A．Heisproudofit.B．Heishopefulofit.C．Heisdoubtfulaboutit.D．Heisunconcernedaboutit.解析：选B推理判断题。根据最后一段中Guam岛农业部的Vice先生说：“这不应该阻止岛民的尝试。我们的长期目标是彻底消灭蛇。”可推断出，Vice先生对解决蛇的问题满怀希望。CAsmallinsectisgettingalotofattentionintheUnitedStates.Therustypatchedbumblebee(大黄蜂)isthefirstofitsspeciestobedeclaredendangeredinthelower48states—meaningeverystateexceptAlaskaandHawaii.Therustypatchedbumblebeeisnamedforarust­coloredlineonitsback.TheUSFishandWildlifeServiceannouncedthismonthitwasaddingthebeetoitsendangeredspecieslist.Theinsectsare“onthebrinkofextinction”，accordingtotheservice.Itsaidthebeeswereoncefoundin28states.Buttherenowareonlysmallpopulationsremainingin13states.Thegovernmentagencywillmakeaplantohelpthedyingbeesrecover.Theagencysaidthatsuchaplanmighthelpotherinsects,likebutterflies.USofficialsthinklandownerscantakesmallstepstohelptherustypatchedbumblebee.Theysaylandownerscanbefriendliertowardsbeesbyusingnativeplantsintheirgardens.Theinsectsdirectlyfertilizemanykindsoffruitandvegetablecrops.Andtheyfertilizegraincropsusedtofeedcattleandmilkcows.Itcostsbillionsofdollarstoduplicatethejobthebeesdoforfree.Landownersarealsobeingurgedtocutbackontheiruseofpesticideproducts.Theofficialsalsosuggestthatgardenersleavetheirplantsaloneattheendofthesummerinsteadofcuttingthem.Thatway,thebeeswillhaveaplacetoliveoverthewinter.TheFishandWildlifeServicesaystherustypatchedbumblebeewasaddedtotheendangeredspecieslistpartlybecauseofhabitatloss.Otherreasonsweredisease,pesticidesandclimatechange.Officialsareworriedthatotherbeeswillsuffer,too.AnotherspeciesofbeesinHawaiiisalsoendangered.语篇解读：本文是一篇说明文。文章介绍了在美国濒临灭绝的锈迹大黄蜂的相关信息。9．Howmanystatesdeclaredtherustypatchedbumblebeeendangered?A．13.
