B．Noisepollution.A．Fishingindustry. D．Climbingtemperatures.解析：細(xì)節(jié)理解題。由第一段最后一句話可知，是全球變暖引起的海水溫度的持續(xù)上升引起了珊瑚礁的白化現(xiàn)象。2．Whatapproachisintroducedtorecoverthecoralreefs？DA．Removingdamagedcoralreefs.B．Usingloudspeakerstokeepfishaway.A．Buildingnewhomesforseaspecies.D．Playingcertainsoundstoappealtofish.解析：推理判斷題。由第二段第一句話可知，通過(guò)播放某些音樂(lè)來(lái)吸引魚(yú)來(lái)病了的珊瑚礁，希望借助它們來(lái)恢復(fù)病了的珊瑚礁的生態(tài)系統(tǒng)。3．WhyareSteveSimpson'swordsquoted？CA．Toprovidesomefindingsofthestudy.B．Toshowtheprogressoftheexperiment.C．Toexplainreasonsforthenewapproach.D．Togiveanothersolutiontotheproblem.解析：推理判斷題。由本段內(nèi)容可推知，本段解釋了這一新辦法的理由。4．Whatcanweinferfromthelastparagraph？CA．Theattemptsareinvain.B．Naturalrecoveryisimpossible.C．Initialsuccesshasbeenachieved.D．Thecoralreefshavereturnedtonormal.解析：推理判斷題。由最后一段可知，該方法已經(jīng)初見(jiàn)成效。B(2021·濟(jì)南市模考)They'reorange,they'rerobotsandthey'recapableofsailingthehighseaswithouthumanintervention.OnTuesdaytheNationalOceanicandAtmosphericAdministration(NOAA)launchedapairofSaildrones(海洋無(wú)人機(jī))inPacificNorthwestwatersforthefirsttime.TheirsummerlongsailingjourneywillstretchfromVancouverIslandtoCalifornia.TheSaildroneoperatorswillcollectdatatohelpsetfuturefishingseasons.Thegovernmentwantstoseewhetherseagoingrobotscanextendfisherysurveysnowperformedbyexpensivemannedships.NoraCohenfromNOAAsaid，“The23-footlongseagoingrobotscanfollowaremotelyprogrammedcourseforuptoayearatatime.Andtheydon'trequireanyfuel.Weusewindandsolarpowertodrivethesensors.”Headded，“Itmeansthatwe'reabletogotoplaceswherewedon'treallywanttosendpeople,andgointoweatherthatwereallydon'twantanyoneevertobein,andbeabletosendmeasurementsback.”Theprimarymissionistoinvestigatethespeciesandthenumberoffishinexistenceandtheplaceswheretheyare.LarryHufnagle,scientistofNOAAFisheriesinSeattle,saidatraditionalbigNOAAresearchship-basedsurveycostsaround$25,000perday.Bycomparison,oneSaildronecosts$2,500perday.“Itcouldbeasignificantsaving，”Hufnaglesaid.“Butlike,anythingelse,thereisatrade-offinwhatyougetandwhatyoudon'tget.Onthemannedship,wehavelimitedtime.Ittakesalotofpeople.Wespendafairamountofmoney.ButthereisonethingtheSaildronecan'tdothathumanscan:castanettocatchandpositivelyidentifythefishdetectedbelow.TheSaildronesaregoingtogiveusadditionaldata,notreplacementdata.”NoraCohensaidSaildrone,aventurecapital-backedcompanybasedinAlameda,California,expectstolaunchatotalof11ofitsseagoingrobotstosurveydifferentwaterbodiesforNOAAthisyear.TheBeringandArcticseas,CoastalCaliforniaandtheGulfofMexicowillbethelocationsofadditionalmissions.文章大意：本文介紹了海洋無(wú)人機(jī)的相關(guān)情況。5．Whatisthepurposeofcollectingfishdata？BA．Toexploretheocean.B．Toassistfishingindustry.C．Tolearnthehabitsoffish.D．Toimprovefishingskills.解析：考查細(xì)節(jié)理解。根據(jù)第二段的第三句“TheSaildroneoperatorswillcollectdatatohelpsetfuturefishingseasons”可知，海洋無(wú)人機(jī)操作員收集數(shù)據(jù)的目的是協(xié)助漁業(yè)。故選B。6．WhatismainlydiscussedabouttheSaildroneinParagraph3？AA．Itsadvantages.B．Itsappearance.C．Itspowersystems.D．Itsprimarymission.解析：考查細(xì)節(jié)理解。根據(jù)第三段的內(nèi)容可知，本段主要介紹了海洋無(wú)人機(jī)遵循遠(yuǎn)程編程航線的時(shí)間長(zhǎng)，不需要任何燃料，能進(jìn)入不想讓人進(jìn)入的地方，能處于不想讓人處于的天氣中，且能發(fā)回測(cè)量的結(jié)果，以上這些都是它的優(yōu)勢(shì)，故選A。7．Whatdoestheunderlinedword“trade-off”inParagraph5probablymean？DA．Debate. B．Reason.C．Reality. D．Balance.解析：考查詞義猜測(cè)。根據(jù)畫(huà)線詞前后的內(nèi)容可知，海洋無(wú)人機(jī)可以省一大筆開(kāi)銷，但是也有我們?nèi)祟惪梢宰龅蕉Ｑ鬅o(wú)人機(jī)無(wú)法做到的事情，即它有利有弊，我們要權(quán)衡得失，故D項(xiàng)的意義與畫(huà)線詞意義最接近。8．Whatcanbeinferredfromthetext？AA．TheSaildronehasapromisingfuture.B．HufnaglethinkslittleoftheSaildrone.C．Mannedshipswillbecompletelyreplaced.D．Productionofseagoingrobotsisrestricted.解析：考查推理判斷。綜合全文可知，海洋無(wú)人機(jī)具有使用成本低、遵循遠(yuǎn)程編程航線的時(shí)間長(zhǎng)、不需要任何燃料、能進(jìn)入不想讓人進(jìn)入的地方且能發(fā)回測(cè)量的結(jié)果等優(yōu)點(diǎn)，能夠幫助確定未來(lái)的捕魚(yú)季節(jié)及進(jìn)行漁業(yè)調(diào)查；且在最后一段談到Saildrone公司今年將預(yù)計(jì)總共推出11款遠(yuǎn)洋航行機(jī)器人，為NOAA調(diào)查不同的水體。由此可推知，海洋無(wú)人機(jī)有好的前景。故選A。Ⅲ.短文改錯(cuò)(2021·廣東省深圳市高級(jí)中學(xué)高三年級(jí)模考)Asweallknow,overseventypercentofourplanetarecoveredbysea,whereisrichinsaltaswellasfish.What'smore,thereisagreatdealofoilorgasunderthesea.Inotherwords,theseaistheplacewithsomanyimportantthingswelivein.However,withtheworldpopulationincreasedrapidly,overfishinghasbecomeaseriousproblem.Everydayalotofrubbishesandwastewaterarepouredintothesea,sotheseaisbadpolluted.Asaresult,thenumberoffishhasobviouslydecreased.Besides,somearedyingoutorhavebeendiedout.Therefore,itistimeforeverybodyprotectthesea.答案：Asweallknow,overseventypercentofourplaneteq\o(are,\s\do8(is))coveredbysea,eq\o(where,\s\do8(which))isrichinsaltaswellasfish.What'smore,thereisagreatdealofoileq\o(or,\s\do8(and))gasunderthesea.Inotherwords,theseaiseq\o(the,\s\do8(a))placewithsomanyimportantthingsweliveseq\o(in,\
