D．popularwithC[词义揣测题。依据其次段画线词所在句中的“shereallydoesn'twanttogobacktodayswhensheoverusedit，wastedtime，stayedupallhoursofthenightonit”可知，ElanaMugdan曾经过度运用手机，奢侈了时间，并且还熬夜玩手机。此处与上文内容相连接，由此可以推想出，此处表示她当时对社交媒体特别痴迷，即上瘾。故选C。]3．WhatdoesElanaMugdanmainlywanttoexpressinParagraph3?A．It'sfantastictohavesomeonetohelpheralltheway.B．It'sunimaginabletoloseherphonenumberontheway.C．It'sunnecessarytorefertoinformationwithasmartphone.D．It'sdifficulttogetoutofthetroublewithoutasmartphone.D[推理推断题。依据第三段第一句“Butnothavingaccesstohersmartphonereallymadecertainsituationsalotharderthanshecouldhaveimaginedthembefore”以及本段所列举的事例可知，ElanaMugdan在第三段想告知我们，没有手机很难摆脱逆境。故选D。]4．WhatcanwelearnaboutElanaMugdan?A．Shecouldn'tlivewithoutasmartphone.B．Shefindsnoonecanhelpherintheadventure.C．Shehasnotwonthegrand$100，000prizeyet.D．Sheusedtousehersmartphonetowritefiction.C[细微环节理解题。依据第四段最终一句中的“she'llkeepitforanotherfourmonths”可知，ElanaMugdan还要接着四个月的挑战，由此可知她还没有获得奖金。故选C。]BClothingrentalisahotnewindustryandretailers(零售商)aredemandingtogetonboardinthehopeofattractinggreenshoppers.Butisrentingfashionactuallymoreenvironmentallyfriendlythanbuyingit，andifso，howmuchmore?JournalistandauthorElizabethClineinvestigatedthisquestionandconcludedthatit'snotassustainableasitseems.Takeshipping，forexample，whichhastogotwowaysifanitemisrented—receivingandreturning.Clinewritesthatconsumertransportationhasthesecondlargestcarbonfootprintofourcollectivefashionhabitaftermanufacturing.Shewrites，“Anitemorderedonlineandthenreturnedcanrelease20kilogramsofcarboneachway，andincreasesupto50kilogramsforrushshipping.Bycomparison，thecarbonimpactofapairofjeanspurchasedfromaphysicalstoreandwashedandwornathomeis33.4kilograms，accordingtoa2015studybyLevi's.”Thenthere'stheburdenofwashing，whichhastohappenforeveryitemwhenit'sreturned，regardlessofwhetherornotitwasworn.Formostrentalservices，thisusuallymeansdry­cleaning，ahigh­impactandpollutingprocess.AlltherentalservicesthatClinelookedintohavereplacedperchloroethylene(全氯乙烯)，acarcinogenic(致癌的)airpollutant，stillusedby70percentofUSdrycleaners，withalternatives，althoughthesearen'tgreateither.Lastly，Clinefearsthatrentalserviceswillincreaseourappetiteforfastfashion，simplybecauseit'ssoeasilyaccessible.There'ssomethingcalled“sharewashing”thatmakespeoplewastemorepreciselybecauseaproductorserviceissharedandthusisregardedasmoreeco­friendly.Uberisoneexampleofthis，advertisedas“awaytoshareridesandlimitcarownership”，andyet“ithasbeenproventodiscouragewalking，bicycling，andpublictransportationuse”．Rentingclothesisstillpreferabletobuyingthemcheapandthrowingtheminthedustbinafterwearingfewtimes，butweshouldn'tlettheavailabilityoftheseservicesmakeustoosatisfied.There'sanevenbetterstep—that'swearingwhatisalreadyinthecloset.【语篇解读】服装租赁是新兴的热门行业，零售商希望以此吸引环保消费者。可是，该行业并不像它看起来的那样绿色环保。它包含的运输环节要比在实体店里买一件衣服然后在家里洗和穿释放的碳多；清洗环节也会污染环境；而且它可能会使我们更追求快时尚从而奢侈得更多。最环保的做法是穿衣橱里原来就有的衣服。5．WhatisElizabethCline'sattitudetowardclothingrental?A．Approving. B．Unfavorable.C．Objective. D．Enthusiastic.B[推理推断题。依据其次段其次句可知，Cline得出的结论是，这个行业并不像它看起来的那样环保；并结合第三至第六段表述的Cline得出这种结论的缘由可推知，Cline并不支持服装租赁，B项意为“不赞成的，否定的，不喜爱的”，故B项正确。C项意为“客观的”，与文意不符。]6．TheUberexampleinParagraph6indicatesthat________．A．rentalservicesareontheriseB．clothingrentalwillbeassuccessfulasUberC．rentingclothesmightwastemorethanexpectedD．rentingclothesmightmakepeopleloseinterestinfastfashionC[推理推断题。依据第六段其次句可知，因为一种产品或服务是共享的，因此就被认为更环保，但这却使人们奢侈得更多。接着下文列举了Uber的例子——它被宣扬为一种共享出行并限制汽车拥有权的方式，但是最终证明它阻碍了步行、骑自行车和公共交通的运用，由此可推知，举Uber这个例子表明白服装租赁造成的奢侈可能比我们想象的多，故C项正确。]7．Theauthorsuggeststhatweshould________．A．giveuprentingclothesB．purchaseinexpensiveclothesC．rentclothesratherthanbuythemD．makefulluseofclotheswe'vepossessedD[细微环节理解题。依据尾段尾句“There'sanevenbetterstep—that'swearingwhatisalreadyinthecloset”可知，作者认为更绿色环保的方法是穿衣橱里已经有的衣服，故D项正确。]8．Whatisthepassagemainlyabout?A．Clothingrentalisanewfashion.B．Clothingrentalisretailers'preference.C．Rentingclothesisnotthateco­friendly.D．Renting­clothesbusinessisinadilemma.C[主旨大意题。通读全文可知，本文第一段引入话题；其次段提出论点——服装租赁业其实并非像它看起来的那样绿色环保；接着第三至第六段给出了论据来支持这一论点；最终一段作者进行总结并给出建议。由此可知，C项符合文意。]Ⅱ.完形填空(2024·山东淄博三模)AsourEarth'stemperaturewarmsupbecauseofclimatechange，itishavingunexpectedeffectsonourworld'sforests.Whentemperaturesrise，treesclosetheirskinsto1thelossofwater，andthis，inturn，slowsdownthe2ofphotosynthesis(光合作用)．Asaresult，thesetreesareshorterandgrowslowly，aswellashavea3deathrate.Climatechangealsoincreasesthe4ofdroughtsandwildfires.Afterwildfires，ittakesawhilefortheforestsystemsto5，andinsomecases，theforestsare6permanently.Treesthatarestressedarealso7toattacksbybacteria.Intropicalforests，vinesthatusethetreesas8canoftenchokethetreesandrobthemofnutrients.Finally，humanshave9theforestlandscapethroughlogging.Whentreesarereplantedonthesoil，theywillnevergrowaslargeasthe10treesthatwerecutdown.Astheseforestsdisappear，speciesthatoncecalledthem“home”areforcedtochange，11thevarietyofthosesystems.12，someendangeredspeciesareunableto13anddie.Old­growthforestsaredisappearinginallregionsofourworld.Whenforestsdie，youngerforeststhatarereestablishedinthesameareagrowbackweakerandsmaller14poorvegetation.Withtreesdyingincreasinglyandcontinuously，willfuturegenerations15outonthewondersofforests?【语篇解读】本文主要说明白地球温度上升对森林产生了意想不到的影响，包括干旱和野火增加，森林消逝，甚至以森林为“家”的物种面临死亡。1．A.protect B．preventC．save D．freeB[依据常识可知，温度上升水分更易蒸发，故可推知树木将皮肤闭合是为了防止水分的流失，prevent意为“阻挡”，故选B项。protect意为“爱护”；save意为“挽救；节约”；free意为“释放”。]2．A.movement B．situationC．process D．operationC[结合后文thesetreesareshorterandgrowslowly和常识可知，树木闭合皮肤来防止水分流失，也会减缓光合作用的进程，process意为“进程”，故选C项。movement意为“活动”；situation意为“状况”；operation意为“操作”。]3．A.higher B．firmerC．lighter D．smallerA[依据上文thesetreesareshorterandgrowslowly可推知，地球气温上升也会导致树木死亡率更高，higher意为“更高的”，故选A项。firmer意为“更坚实的”；lighter意为“更光明的”；smaller意为“更小的”。]4．A.choice B．measureC．qualification D．chanceD[依据下文Afterwildfires...可知，全球气温上升增加了干旱和野火发生的可能性，chance意为“可能性；机会”，故选D项。choice意为“选择”；measure意为“措施；方法”；qualification意为“资格”。]5．A.grow B．remainC．recover D．declineC[依据上文Afterwildfires，ittakesawhilefortheforestsystemsto且结合常识可知，遭受野火之后森林系统须要时间才能复原，recover意为“复原常态”，故选C项。grow意为“生长”；remain意为“停留”；decline意为“削减”。]6．A.ignored B．lostC．hurt D．leftB[依据上文遭受野火后森林须要时间来复原，以及前后关键词insomecases，permanently可知，某些状况下，森林恒久复原不了了，lose意为“失去”，故选B项。ignore意为“忽视”；hurt意为“受伤”；leave意为“离开”。]7．A.accessible B．enjoyableC．acceptable D．favorableA[依据设空处前的also可知，此处接着讲解并描述树木面临的问题：简单受到细菌的攻击。accessible意为“易接近的”，固定搭配beaccessibleto意为“简单进入的，简单接近的”，故选A项。enjoyable意为“令人欢乐的”；acceptable意为“可接受的”；favorable意为“有利的；赞同的”。]8．A.attention B．commandC．trust D．supportD[依据上文vinesthatusethetreesas可知，藤本植物是利用树木的养分，以树木为支撑的，support意为“支撑；支持”，故选D项。attention意为“留意”；c
