和其他海洋物种离开它们。科学家们为修复这一脆弱的生态系统进行了研究,在水下使用扬声器来吸引鱼群,以帮助恢复受损的珊瑚礁。1.Whatisthefirstparagraphmainlyabout?A.Theimportanceofcoralreefs.B.Theinfluen

ceofclimatechange.C.Theperfectplaceforseaspecies.D.Theecosystem’sdiversityandcomplexity.答案A解析段落大意题。第一段讲的内容是:珊瑚礁是海洋生物的必要组成部分,不但为各

种海洋生物提供住所和栖息地,还提供和回收利用营养物,使鱼类种群与其他物种一起繁荣发展,形成一个健康和多样化的生态系统。故选A项。2.What’sthepurposeofusingspeakersunderwate

r?A.Tomakefishmoreactive.B.Totestdamagedcoralreefs.C.Tohelprecovertheecosystem.D.Tohelpspeedthegrowthofcoralreefs.答案C解析细节理解题。根据第三段内容可知,为了修

复脆弱的生态系统,科学家们在水下使用了扬声器,故选C项。3.Whichofthefollowingistrueabouttheexperiment?A.Itwasn’tcarriedoutinthelargestcoralreefsystem.B.Itdrewmuchpublicatten

tion.C.Ithasbroughtdeadcoralreefsbacktolife.D.Theloudspeakerswerehelpfulinattractingfish.答案D解析细节理解题。根据第四段中的“Byusin

gloudspeakers...wherenosoundswereplayed.”可知,与未播放声音的地方相比,该实验中用扬声器产生的声音为死去的珊瑚礁吸引了两倍多的鱼,故D项正确。4.WhatisMarkMeekan’sattitudetowardstheuseofspeaker

s?A.Doubtful.B.Positive.C.Disappointed.D.Indifferent.答案B解析推理判断题。根据最后一段内容可知,扬声器可以吸引鱼群,鱼群虽然不会使死珊瑚礁自动复活,但其恢复过程依赖鱼清洁珊瑚礁,以给珊瑚重新生长的空间,

故可知MarkMeekan对使用扬声器持肯定的态度。B主题语境:人与自然语篇类型:说明文难度:★★★☆☆Likecolourfulcorals,theyrockedgentlyintheoceancurr

积累了大量的塑料垃圾。从远处望去,潜水员仿佛看到了一个色彩缤纷并随着洋流缓缓流动的海底世界。它们是数万吨的塑料废物,在这里堆积如山,形成了一种“珊瑚礁”。5.Whatdoestheunderlinedword“it”(Para.3)mos

tprobablyreferto?A.TheAegeanSea.B.Plasticpollution.C.Thevolunteergroup.D.Thewastesite.答案B解析代词指代题。根据上文的“

fthepollutionoffAndros?A.Collapseofawastesite.B.Extremelybadweather.C.Wastethrownawaybytourists.D.Pl

asticwasteproducedbytheGreeks.答案A解析细节理解题。根据第四段最后两句“TheseapollutionoffAndrosisthoughttodatebackto2011,whenheavyraincausedawa

stesitetocollapse.Mostofthewastefellintothesea.”可知,污染的开始是垃圾场的坍塌。7.WheredoestherubbishfinallyendupaccordingtoRoss?A.Theoceans.B.

Inthefields.C.Intherubbishsites.D.Thewastetreatmentfactories.答案A解析推理判断题。根据最后一段Ross所说的话“Ifpeoplearewonderingwhe

retheirrubbishendsup,weseeiteachtimewegointothewater”可知,垃圾最终进入了海里。8.Whatcouldbethebesttitleforthepassage?A.GulfofPlasticCorals’F

oundinAegeanSeaB.TheParadiseLiesintheCaribbeanSeaC.CoralReefsAreFullofEveryColourD.WaterPollutionIsVerySerious答案A解析主旨大意题。通读全文可知,潜水员在

希腊安德罗斯岛的水下仿佛看到了一个色彩缤纷并随着洋流缓缓流动的海底世界。那是数万吨的塑料废物,在这里堆积如山,形成了一种“珊瑚礁”。由此可知,A项可作为本文的标题。
