1.Whydidthewritermentionthesharks,smellatthebeginningofthepassage?A.Becausethewriterappreciatestheirabilitytofindfood.B.Becausethewriterconsidersthemdangeroustohumanbeings.C.Becausethewriterintendstoshowhowtocontrolweedintheocean.D.Becausethewriterworriesaboutthesharksintheocean.答案D解析推理判斷題。作者在第一段中提到鯊魚的嗅覺,主要是引出主題,即:海洋環(huán)境的改變會(huì)對(duì)鯊魚的覓食能力造成危害。因此可以推知作者擔(dān)心生活在海洋中的鯊魚,故選D項(xiàng)。2.WhatisParagraph3mainlyabout?A.Whattheoceaninthefuturewillbelike.B.WhohelpedDixsonconductthestudy.C.Whatkindsofpoolswereusedduringthestudy.D.Whatthelevelsofcarbondioxidewillbeatintheoceaninthefuture.答案C解析段落大意題。根據(jù)第三段的內(nèi)容可知,本段主要是講Dixson和她的團(tuán)隊(duì)把鯊魚放在哪些池子里做實(shí)驗(yàn),故選C項(xiàng)。3.Theresearcherspumpedwaterwhereadeadsquidhadbeenovernightto.

A.helpthesharkslookforfoodB.testthesharks’senseofsmellC.provethatsharkslikeeatingsquidsD.explainwhycarbondioxideintheoceanaffectssharks答案B解析推理判斷題。根據(jù)第四段的內(nèi)容“Inonestream,theresearcherspumpedwater,inwhichadeadsquidhadbeenovernight.Thiswatersmelledstronglyofthesquid.Theotherstreamcontainedoceanwaterwithnoscent(氣味).Becauseeachstreamflowedatthesamerateandinthesamedirection,thesquidsmellstayedinitsstream.Thesharkscouldchoosetoswimineitherstream.”可推知研究人員往水池里放了帶魷魚味的水,其目的是測(cè)試鯊魚在特定的環(huán)境下能否聞到那種氣味,故選B項(xiàng)。4.Whatdoestheunderlinedsentenceinthelastparagraphsuggest?A.Sharkslikethesquidscentedstreambetter.B.Sharkslikethestreamwiththehighlevelofcarbondioxide.C.Sharksspent15%oftheirtimeinthesquidscentedstream.D.Thehighlevelofcarbondioxidecanaffectthesharks,abilitytosmell.答案D解析句意猜測(cè)題。畫線句子的意思是“但是,曾置身于最高濃度的二氧化碳中的鯊魚只在魷魚味的水中待了僅僅15%的時(shí)間”。由此可知,Dixson團(tuán)隊(duì)的實(shí)驗(yàn)發(fā)現(xiàn),鯊魚的嗅覺的確受到二氧化碳濃度的影響,故選D項(xiàng)。BTailSpinTwodolphinsracearoundinabigpoolintheOceanPark.Thesmallerdolphin,Grace,showsoffafewofhertricks,turningaroundandwavinghellotothecrowd.Themostamazingthingabouther,however,isthatshe’sevenswimmingatall.Shedoesn’thaveatail.Gracelosthertailasababywhenshegotcaughtupinafishtrap.WhenthedolphinarrivedattheOceanParkinDecember2005,shewasfightingforherlife.“Isshegoingtomakeit?”Hertrainer,AbbeyStone,fearedtheworst.Gracedidmakeit—buthertaildidn’t.Sheendeduplosingherflukesandthelowerpartofherpeduncle.Overthepastsixyears,shehaslearnedtoswimwithouthertail.Dolphinsswimbymovingtheirflukesandpeduncleupanddown.Gracetaughtherselftomoveanotherway—likeafish!Shepushesherselfforwardthroughthewaterbymovingherpedunclefromsidetoside.ThemovementsputharmfulpressureonGrace’sbackbone.Soapanyofferedtocreateamanmadetailforher.ThetailhadtobestrongenoughtostayonGraceassheswambutsoftenoughthatitwouldn’thurther.ThefirsttimeGraceworetheartificialtail,shesoonshookitoffandletitsinktothebottomofthepool.Now,sheisstilllearningtousethetail.Somedaysshewearsitforanhouratatime,othersnotatall.“Thenewtailisn’tnecessaryforhertofeelfortable,”saysStone,“butithelpstokeepthatrangeofmotion(動(dòng)作)andbuildmuscles(肌肉).”Now,thedolphinisabouttogetanevenhappierending.Thismonth,GracewillstarinDolphinTale,afilmthatfocusesonherrescueandrecovery.Herprogresshasinspiredmorethanjustanewmovie.Manypeopletravelfromnearandfartomeether.SeeingGraceswimwithhermanmadetailgivespeoplesomuchcourage.5.WhenGracefirstarrivedattheOceanPark,hertrainerworriedabouther.
