B.Safeandfashionable.C.Commonandcomfortable.D.Eco-friendlyandeconomical.答案D解析细微环节理解题。依据其次段第一句中的toreducegreenhousegases和第三段第一句中的energy-savingelectriccars可知,EdCharrier认为驾驶电动汽车可以削减温室气体的排放量,也可以节约能源,所以是环保的和经济的。故选D项。25.WhatdoweknowaboutLeafRapids’historicby-lawtobanplasticbags?A.Itattractedlotsofattention.B.Itwasquestionedbyitscitizens.C.Itbroughtaboutmanyproblems.D.Itcausedlegalactionfromtheplasticsindustry.答案A解析推理推断题。依据第五、六段可知,数以百计的地方官员打电话询问该地方法规的状况,甚至有地方进行效仿,对此EdCharrier说“Inevereverdreamtthatitwouldbethisbig”,由此推知,该地方法规反响很大,引起了很多人的关注。故选A项。26.WhatdoesEdCharriermeanbysaying“Butnothinghascomeofit”inparagraph7?A.TheCPIAhasn’ttakenhistowntocourt.B.TheCPIAhasn’tstartedanyrecyclingprogrammes.C.TheCPIAhaswonnolegalsupportfromcourt.D.TheCPIApaysnoattentiontotheprotectionofenvironment.答案A解析推理推断题。依据第七段可知,对于LeafRapids的做法,加拿大塑料制品产业协会只是发出了提起法律诉讼的威逼,其发言人CathyCirco在讲话中只是说:我们认为LeafRapids的行为是不合法的。他们只是对LeafRapids的做法表达了是否合法的疑问和不满,并没有实行实际的法律行动。故选A项。27.What’sthemainideaofthetext?A.Asmalltownisbanningplasticshoppingbags.B.Asmalltownisplanningtobangas-poweredvehicles.C.Asmalltownistakingmeasurestoprotecttheenvironment.D.Asmalltownhasbecomethebiggestenemyoftheplasticsindustry.答案C解析主旨大意题。全文主要讲解并描述了加拿大北部小镇LeafRapids继禁止运用塑料袋后又推出一项爱护环境的措施。故选C项。CThegüiñaisknownasthelittletigercat,littlespottedcatorChileancat.Abouthalfthesizeofthepetcat,itisoneofthemostthreatenedcatspeciesinSouthAmerica.ThewildcatlivesonlyincentralandsouthernChileandinalongnarrowareaofArgentina.AccordingtotheIUCN,thereareonlyabout10,000leftinthewild.Itsnaturalhomeisrainforest,butithasalsobeenseeninpineoreucalyptus(桉树)plantations(种植园)orclosetoagriculturalareas.ResearchledbytheUniversityofKent,UK,foundthatdestructionoftheirlivingenvironments,andthesubdivision(细分)oflargefarmsintosmallerones,arethebiggestdangers.“Thisisbecausethereisahigherriskofhumanactivitiesandhuntinginareaswheretherearemorefarms;agreaterpressureonnaturalresourcesthroughincreasedcuttingtreesandlivestockfarming(畜牧业);andevencompetitionforfoodfromanimalskeptaspets,”saidDrNicolsGlvez,whoisnowalectureratthePontificiaUniversidadCatólicadeChile.Morethantwo-thirdsofChile’srainforestshavebeenlostover25years.However,throughaseriesofquestionnaires,camera-trapdataandremote-sensedpicturestheresearchersfoundthatthegüiñaisadaptabletoforestlossinasurprisinglyway.Theysaylarge,intensive(集约的)agriculturalareasareactuallysuitableforthegüiñaandshouldnotbelookedonaspoorqualityhabitats.Thisisbecausetherearemanyunfarmedareasthatprovideshelters,foodresourcesandsuitableconditionsfortakingcareofyoung,theysay.Anotherthreatisillegalkillingbyhumans.Thecatisthoughtlittleofinthecountrysideoverfearsthatitwillkillchickens.Questionnairesshowedthat10%offarmershadkilledagüiñainthelastdecade.“Thissuggeststhatillegalkillingismuchlessofathreattotheirsurvivalthanthesubdivisionoffarms,”saidProfZoeDavies,fromtheDurrellInstituteofConservationandEcology(DICE)attheUniversityofKent.28.Whichcharacteristicisuniquetothegüiñas?A.Theyareasbigasthepetcats. B.TheyliveonlyinSouthAmerica.C.Theyareendangeredwildanimals. D.Theyprefertolivingintherainforests.答案B解析推理推断题。依据第一段中的“ThewildcatlivesonlyincentralandsouthernChileandinalongnarrowareaofArgentina.”并结合常识可推断出B项正确,因为智利和阿根廷都属于南美洲。29.Whydopeopleinthecountrysidehaveacustomofkillinggüiñas?A.Becausepeoplewanttotakemorelandfromgüiñas.B.Becausegüiñasarethoughttobringbadlucktopeople.C.Becausegüiñasareconsideredpestsastheycanstealchickens.D.Becausegüiñasarelookedonasevilsastheycanspreaddiseases.答案C解析细微环节理解题。依据第六段叙述可知,农村地区的人对山原猫持负面看法是因为这种猫常常捕食他们饲养的鸡。30.Whatdoestheunderlinedword“habitats”inparagraph5referto?A.Thesuitablefoodsthatananimalmainlyliveson.B.Theobviousreasonswhyananimalisactuallyindanger.C.Theterriblefactorsthataffectanimals’safetyandhealth.D.Thenaturalenvironmentswhereananimalnormallylives.答案D解析词义揣测题。结合该词所在的句意可知,大型集约化的农田事实上是适合山原猫生活的,故此不能将其看作是劣质的栖息地,因为这里有很多未开垦的区域为山原猫供应庇护和食物,故habitat意为“栖息地”。31.Whatconclusiondoestheresearchshowaboutthegüiñas?A.Theyareabletosurvivenearhumansettlementsonagriculturallands.B.Largeagriculturallandsarenotsuitableforthegüiñastosurvivein.C.Güiñasprefertheagriculturallandstotraditionalrainforests.D.Güiñasneedtodevelopnewskillstoadapttothechangeofclimate.答案A解析推理推断题。依据第四、五段的叙述可知,山原猫已经很好地适应了其栖息地的改变,在人类居住地旁边的农田里能生存下来。DWe’reoftenremindedoftheimportanceofpreservingtheplanetasweseeitforfuturegenerations—andchildrenatStOswald’sCEPrimarySchoolinChestercertainlyagree.Nine-year-oldIsobelKelleherfromtheschool’sHummingbirdsclassthinksadultsneedtotakenotes.“SometimestheycanbebusyandIdon’tthinktheythinktheycanmakeadifference,butifeveryonedoesalittlebit,italladdsup,”shetellsHuffPostUK.“Westartedlookingatplasticpollutioninouroceansandthethingslikeplasticbagsthatarepollutingthem,”shesays.“Fishcaneattheplasticandtheycandie,orwemighteveneatthefishourselves.”MrTimms,Isobel’steacher,hasbeenleadinganewprojectattheschoolwhichletschildrenloosecreativelytoraiseawarenessoftheneedtobemoreenvironmentallyfriendly.TheentireHummingbirdsclass,whichismadeupof9-and10-year-oldpupils,hasbeenbusywritingpoemsandcreatingonlinevideoadvertisementstowarnadultsabouttheserioussituationofouroceansandwildlife.MrTimmsthinkschildrenhaveanimportantroletoplayinteachingushowtotakecareofthethingsaroundus.“Wesometimesoverlookhowmuchwecanreallylearnfromchildren,”hesays.“Ithasbeenreallyhardtobelievehavingparentscomeinsayingthattheirchildrenhavebeenaskingthemtostopusingplastic,andtorecyclemore,andevenstoppingthemusingplasticstraws.”MrTimmsisproudofhisHummingbirdsclass.“Themessagethattheywouldliketosendtotheworldissimple:stoppingthisisn’tsomeoneelse’sjob,anditwon’tbeOKifwejustleaveit.”32.WhatcanweinferaboutadultsaccordingtoIsobelKelleher?A.Theyjustpretendtobebusy. B.Theyhaven’tdonetheirpartwell.C.Theycandonothingtostoppollution. D.Theyhavestartedtocareabouttheoceans.答案B解析推理推断题。依据其次段内容,尤其是第一句“Nine-year-oldIsobelKelleherfromtheschool’sHummingbirdsclassthinksadultsneedtotakenotes.”可知,学校“蜂鸟班”里9岁的伊泽贝尔认为成年人须要留意环保问题,由此可推知,成年人在环保问题上做得不够好。故选B项。33.Whatisthepurposeoftheschoolproject?A.Tohelpadultstolearnmoreabouttheirkids.B.Topersuadestudentstostopusingplasticbags.C.Toteachstudentshowtowritepoemscreatively.D.Toremindadultstobefriendlytotheenvironment.答案D解析细微环节理解题。依据第三段中的towarnadultsabouttheserioussituationofouroceansandwildlife可知,“蜂鸟班”的学生们始终忙着写诗和制作在线视频广告,提示成年人海洋和野生动物所处的严峻境况,由此可知,该项目旨在提示成年人要留意环保问题。故选D项。34.WhydoesMrTimmsmentionparentsinparagraph4?A.Toattractpeopletosupporthiswork. B.Tohaveadultscareabouteducation.C.Toshowtheeffectsoftheproject. D.Toprovekidsarecreativeinteaching.答案C解析推理推断题。依据第四段中的“Ithasbeenreallyhardtobelievehavingparentscomeinsayingthattheirchildrenhavebeenaskingthemtostopusingplastic,andtorecyclemore,andevenstoppingthemusingplasticstraws.”可知,真的很难信任有父母说孩子们要求他们停止运用塑料,并回收更多的塑料,甚至阻挡他们运用塑料吸管,由此可推知,该段提及父母旨在说明该项目的影响。故选C项。35.Whatisthebesttitleforthetext?A.AnInspiringSchoolProject B.AnAppealtoStopPlasticBagsC.SeriousSituationsofOurPlanet D.Adults’IgnoranceoftheEnvironment答案A解析标题归纳题。第三段第一句“MrTimms,Isobel’steacher,hasbeenleadinganewprojectattheschoolwhichletschildrenloosecreativelytoraiseawarenessoftheneedtobemoreenvironmentallyfriendly.”为全文的主题句,结合全文内容可知,本文主要介绍了“蜂鸟班”主动响应一个环保教化项目,该班由9岁和10岁的孩子组成,他们通过写诗和制作在线视频广告,提示成年人留意环保问题。故选A项。其次节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。StayhealthywhilegroceryshoppingGoattimesofthedaywhenit’slessbusy.Youmightnotbeamorningperson,butgoingtothegrocerystorebrightandearlywhenthey’rejustopeningmightbeyourbestoption.36Thevirusismainlyspreadthroughclosecontactwithotherpeople.Inaddition,manystoressanitise(消毒)overnight,sotheenvironment,ingeneral,islessgermy.Manystoresarecurrentlyofferingspecialmorninghourswhereonlyseniorcitizensareallowedtoshop.37
