新高考英語二輪復習課時練第1部分閱讀理解與閱讀七選五專題1第7 體裁微解說明文 (含解析)

第7講體裁微解——說明文說明文通常是通過舉例子、作比較、分類別、析結(jié)果、列數(shù)字和作引用等手段，具體描述一項研究或者介紹一項新產(chǎn)品、新技術(shù)，讓讀者了解信息，說明文通常不包含作者的個人觀點。主要具有以下特點：選材實驗報告、產(chǎn)品介紹、場館介紹、社會現(xiàn)象分析以及語言文化、人文地理、生物的生存狀況等。內(nèi)容用平實的語言客觀解說事物、解釋現(xiàn)象、提供信息，即說明一個事物，說明一項研究。形式總分式(事物說明文常用“總—分”式、“總—分—總”式結(jié)構(gòu))；遞進式(事理說明文由淺入深、由表及里、由現(xiàn)象到本質(zhì)，逐層遞進，剖析事理)；并列式(文章各部分內(nèi)容沒有主次輕重之分)；對照式(通過兩個事物的對照和比較說明其異同)。語言主要考查考生對詞匯和句式的掌握和運用情況。說明文因其生僻詞匯多、句式復雜等特點，相對于其他體裁的文章來說難度更大。命題主要集中在細節(jié)理解題、推理判斷題、主旨大意題或詞義猜測題。出題人經(jīng)常在長難句上做文章。說明文閱讀量大，生僻詞匯多，句式結(jié)構(gòu)復雜，題目往往涉及推理判斷題和主旨大意題。因此，閱讀這類文章時，應把握文章結(jié)構(gòu)，弄清作者所要說明的事物；另外，考生在平時的學習中應多積累閱讀詞匯，提高分析長難句的能力。具體答題策略如下：策略指導技法解讀抓首尾段首段往往提出說明文的主題，尤其是研究類說明文，研究結(jié)果就是主題；尾段往往重申強調(diào)主題。梳理文章結(jié)構(gòu)整體敘述＋細節(jié)或過程說明＋概括評述；現(xiàn)象＋原因＋后果/啟示/措施；研究發(fā)現(xiàn)/調(diào)查結(jié)果＋研究/調(diào)查過程。破解長難句結(jié)合語境和所學語法知識破解結(jié)構(gòu)復雜的長難句。(2022·新高考全國Ⅰ·B)Likemostofus，Itrytobemindfuloffoodthatgoestowaste.Thearugula(芝麻菜)wastomakeanicegreensalad，roundingoutaroastchickendinner.ButIendedupworkinglate.Thenfriendscalledwithadinnerinvitation.Istuckthechickeninthefreezer.Butasdayspassed，thearugulawentbad.Evenworse，Ihadunthinkinglyboughtwaytoomuch;IcouldhavemadesixsaladswithwhatIthrewout.Inaworldwherenearly800millionpeopleayeargohungry，“foodwastegoesagainstthemoralgrain，”asElizabethRoytewritesinthismonth’scoverstory.It’sjaw-droppinghowmuchperfectlygoodfoodisthrownaway—from“ugly”(butquiteeatable)vegetablesrejectedbygrocerstolargeamountsofuneatendishesthrownintorestaurantgarbagecans.Producingfoodthatnooneeatswastesthewater，fuel，andotherresourcesusedtogrowit.Thatmakesfoodwasteanenvironmentalproblem.Infact，Roytewrites，“iffoodwastewereacountry，itwouldbethethirdlargestproducerofgreenhousegasesintheworld.”Ifthat’shardtounderstand，let’skeepitassimpleasthearugulaatthebackofmyrefrigerator.MikeCurtinseesmyarugulastoryallthetime—butforhim，it’smorelike12boxesofdonatedstrawberriesnearingtheirlastdays.CurtinisCEOofDCCentralKitcheninWashington，D.C.，whichrecoversfoodandturnsitintohealthymeals.Lastyearitrecoveredmorethan807,500poundsoffoodbytakingdonationsandcollectingblemished(有瑕疵的)producethatotherwisewouldhaverottedinfields.Andthestrawberries？Volunteerswillwash，cut，andfreezeordrythemforuseinmealsdowntheroad.Suchmethodsseemobvious，yetsooftenwejustdon’tthink.“Everyonecanplayapartinreducingwaste，whetherbynotpurchasingmorefoodthannecessaryinyourweeklyshoppingorbyaskingrestaurantstonotincludethesidedishyouwon’teat，”Curtinsays.語篇解讀本文是一篇說明文。文章介紹了我們?nèi)粘Ｉ钪械氖澄锢速M現(xiàn)象以及Washington，D.C.中央廚房的首席執(zhí)行官Curtin為解決食物浪費而采取的努力。24．Whatdoestheauthorwanttoshowbytellingthearugulastory?A．Wepaylittleattentiontofoodwaste.B．Wewastefoodunintentionallyattimes.C．Wewastemorevegetablesthanmeat.D．Wehavegoodreasonsforwastingfood.答案B解析推理判斷題。根據(jù)第一段內(nèi)容可推知，作者想通過講述芝麻菜的故事來表明我們有時會無意間浪費食物。故選B。25．Whatisaconsequenceoffoodwasteaccordingtothetext?A．Moraldecline.B．Environmentalharm.C．Energyshortage.D．Worldwidestarvation.答案B解析細節(jié)理解題。根據(jù)第三段可知，浪費食物的一個后果就是會造成環(huán)境問題。故選B。26．WhatdoesCurtin’scompanydo?A．Itproduceskitchenequipment.B．Itturnsrottenarugulaintocleanfuel.C．Ithelpslocalfarmersgrowfruits.D．Itmakesmealsoutofunwantedfood.答案D解析細節(jié)理解題。根據(jù)第四段中的“CurtinisCEOofDCCentralKitcheninWashington，D.C.，whichrecoversfoodandturnsitintohealthymeals.”可知，Curtin的公司可以將不需要的食物重新做成健康膳食，故選D。27．WhatdoesCurtinsuggestpeopledo?A．Buyonlywhatisneeded.B．Reducefoodconsumption.C．Goshoppingonceaweek.D．Eatinrestaurantslessoften.答案A解析細節(jié)理解題。根據(jù)最后一段Curtin所說的話可知，Curtin建議人們不要買過多的食物，購買自己所需要的量就好，故選A。A(2022·安徽江南十校一模聯(lián)考)Foodmadefromatmosphericcarboncouldfeedtheworldwhilehelpingtofightclimatechange，accordingtoSolarFoods，aFinnishcompanyfoundedin2017.“WecancollectCO2anywhere，”saiditsCEOPasiVainika，whosecompanyhasdevelopedaproteinpowdermadeusingCO2.“That’sastrategicshiftwhererawmaterialsareintheair.”Theproteinpowder，calledSolein，canbeturnedintomeatanddairysubstitutesoraddedtofoodsandshakes.SolarFoodsusesspecialunitstopullCO2fromtheatmosphere.Toturnitintoprotein，microbes(微生物)，similartothoseintheproductionofwineandyogurt，willbefedonittogrowandreproduce.Duringtheprocess，waterissplitintohydrogenandoxygen.Alongwithagrowthmediumcontainingnecessaryminerals，thethreegasesarepumpedintofeedthemicrobes.Harvestedanddried，thatremainingmixturebecomesSolein—ayellowpowdermadeupofsingle-cellprotein，withanutrientcompositionsimilartowheatflour.SolarFoodsclaimsthatSoleinremovesmostoftheemissionsassociatedwithmodernagriculture，whichisresponsibleforalmostone-thirdofallgreenhousegasemissions.“OnekilogramofSoleinsendsout0.2kilogramofCO2e(二氧化碳當量)．Incomparison，beefherdsproducearound100kilogramsandchicken10kilograms，”saidVainikka.“Wecanremovetheclimateimpactofmodernfoodsystemsontheplanet，whichtodayaccountforabout30percentofglobalgreenhousegasemissions.”Hefurtherstressedthatwhilethecompany’sfactoriesalsorequiresomelandusedforindustrialfarming，onlyaboutone-tenthofthelandisneededcomparedtophotosynthesis(光合作用)．“Wecouldfreeupagriculturallandtogrowbackforests，”headded，“andthoseremovecarbonpermanentlyfromtheatmosphere.”Probablyoptimistsarenowc
