閱讀理解的結(jié)構(gòu)化整理（說明文1）-教師版

閱讀理解的結(jié)構(gòu)化整理（說明文1）一、說明文結(jié)構(gòu)1.總分式（1）總分（無結(jié)尾）：《蘇州園林》（2）總分總：《故宮博物館》（3）分總2.并列式文章沒有主次輕重之分：《論讀書》，三個部分分別談到了讀書的目的、讀書的方法、讀書的好處。3.連貫式各層之間按照事物發(fā)展過程安排層次，（時間為線索）前后互相承接。4.遞進式各層之間的關(guān)系是由淺入深、由表及里、由現(xiàn)象到本質(zhì)。各層之間的關(guān)系是遞進的。如《向沙漠進軍》。遞進結(jié)構(gòu)的主要形式有：①現(xiàn)象——本質(zhì)；②特點——用途；③原因——結(jié)果；④整體——部分；⑤主要——次要；⑥概括——具體。二、說明一項發(fā)明或發(fā)現(xiàn)結(jié)構(gòu)分析典例分析（2022·吉林·東北師范大學(xué)）Ajointresearchteamrecentlyhavedevelopedanewelectronicskinthatissimilartohumanskininstrength,durabilityandsensitivity.Theskinoreskinmayplayanimportantroleinnextgenerationpersonalizedmedicine,softroboticsandartificialintelligence.“Theidealeskinwillmimic(模仿)themanynaturalfunctionsofhumanskin,suchassensingtemperatureandtouch,accuratelyandinrealtime,”saysleadingresearcherYichenCai.However,makingsuitablyflexibleelectronicsthatcanperformsuchdelicatetaskswhilealsousedrepeatedlyischallenging,andeachmaterialinvolvedmustbecarefullyengineered.Mosteskinsaremadebyputtinganactivesensoronthesurfacethatattachestohumanskin.However,theconnectionbetweenthemisoftentooweak,whichreducesthedurabilityandsensitivityofthematerial;otherwise,ifitistoostrong,itwon’tbeflexibleenough,makingitmorelikelytobreakthecircuit.“Thelandscapeofskinelectronicskeepsshiftingataremarkablepace,”saysCai.“Thediscoveryof2Dsensorshasacceleratedeffortstoturnthesequitethinbutstrongmaterialsintofunctional,durableartificialskins.”Thenewmanmadeskinbuiltbytheresearcherscouldsenseobjectsfrom20centimetersaway.Itcouldfurthermakeaquickresponsewhentouchedinlessthanonetenthofasecond.“Itisastrikingachievementforaneskintomaintaintoughnessafterrepeateduse,”saidShen,“whichmimicsthesoftnessandrapidrecoveryofhumanskin.”Thistypeofeskincouldmonitorarangeofbiologicalinformation,suchaschangesinbloodpressure,whichcanbedetectedfrommovementsofarmsandlegs.ThisdatacanthenbesharedandstoredonthecloudviaWiFi.“Oneremainingproblemtothewidespreaduseofeskinsliesinmassproductionofhighresolutionsensors,”addsgroupleaderVincentTung,“however,thelatesttechnologyoffersnewpromise.”（1）第一段：發(fā)明的內(nèi)容、好處（eskin）（2）第二段：用途、功能（模仿人類皮膚的功能）（3）第三段：原理（4）第四段：前景（5）第五段：功能、優(yōu)勢（感知物體）（6）第六段：功能、用途（生物）（7）第七段：潛在問題1．What’sthefeatureoftheneweskin?A．It’sflexibleandsensitive. B．Itisalmostthesameashumanskin.C．Ithasfragileelectronics. D．IthasprovedimportantinareaslikeAI.【解析】根據(jù)文章第一段內(nèi)容“Ajointresearchteamrecentlyhavedevelopedanewelectronicskinthatissimilartohumanskininstrength,durabilityandsensitivity.(最近，聯(lián)合研究小組開發(fā)出了強度、耐用性、敏感性與人類皮膚相似的新型電子皮膚。)”可知，這種新型的電子皮膚在強度，耐用性，敏感性方面與人類皮膚類似，且文章第五段內(nèi)容“Thenewmanmadeskinbuiltbytheresearcherscouldsenseobjectsfrom20centimetersaway.Itcouldfurthermakeaquickresponsewhentouchedinlessthanonetenthofasecond.(研究人員制造的新型人造皮膚可以感知20厘米外的物體。當(dāng)被觸碰時，它還能在不到十分之一秒的時間內(nèi)做出快速反應(yīng)。)”提及它可以感知到20厘米外的物體，在感知度上具有敏感性；當(dāng)被觸碰時反應(yīng)迅速，具有靈活性，由此可知，這種新型電子皮膚具有靈活性和敏感性。故選A項。2．Whatcantheneweskindo？A．Itcanrapidlyreacttotouches. B．Itcanchangehuman’sbloodpressure.C．Itcanhealthewoundedskinquickly. D．Itcanadjusthuman'stemperature.【解析】根據(jù)文章第五段內(nèi)容“Itcouldfurthermakeaquickresponsewhentouchedinlessthanonetenthofasecond.(當(dāng)被觸碰時，它還能在不到十分之一秒的時間內(nèi)做出快速反應(yīng)。)可知，當(dāng)這種電子皮膚被觸碰時，它能在不到十分之一秒的時間內(nèi)快速反應(yīng)，即，它能迅速對觸摸做出反應(yīng)。故選A項。3．Whatdoestheunderlinedword“striking”inparagraph5probablymean？A．Slight. B．Noticeable. C．Wellknown. D．Insignificant.【解析】分析可知，劃線單詞“striking”為形容詞，修飾名詞“achievement(成就)”，根據(jù)后文的描述“‘…foraneskintomaintaintoughnessafterrepeateduse,’saidShen,‘whichmimicsthesoftnessandrapidrecoveryofhumanskin.’(“……電子皮膚在反復(fù)使用后仍能保持韌性，”沈說，“這模仿了人類皮膚的柔軟和快速恢復(fù)。”)”，與前文“However,theconnectionbetweenthemisoftentooweak,whichreducesthedurabilityandsensitivityofthematerial;otherwise,ifitistoostrong,itwon’tbeflexibleenough,makingitmorelikelytobreakthecircuit.(然而，它們之間的聯(lián)系往往過于薄弱，降低了材料的耐久性和敏感性；否則，如果它太堅固，它就不夠靈活，更有可能破壞電路。)”提及的大部分“舊皮膚”對比來說，能夠在反復(fù)使用后仍保持韌性是很大的成就和進步。由此可推知，“striking”應(yīng)是表達“巨大的；顯著的”含義。故選B項。4．Whatisthebesttitleforthetext?A．ABreakthroughinHighTechnology B．ManmadeSkinImprovedC．Eskin,aPromisingBusiness D．TheWideSpreadUseofEskin【解析】文章首句內(nèi)容“Ajointresearchteamrecentlyhavedevelopedanewelectronicskinthatissimilartohumanskininstrength,durabilityandsensitivity.(最近，聯(lián)合研究小組開發(fā)出了強度、耐用性、敏感性與人類皮膚相似的新型電子皮膚。)”揭示文章的核心話題，即，文章主要以一種新的電子皮膚為核心話題，講述了它在強度，耐用性和敏感性方面與人類皮膚相似，而這種新的電子皮膚在新技術(shù)的推動下有望大量生產(chǎn)。選項B“ManmadeSkinImproved(人造皮膚改善)”貼合主題。故選B項。注意選項D，要翻譯成電子皮膚的廣泛使用，但是并沒有廣泛使用，并且D選項沒有升華。實戰(zhàn)演練（一）（2022·四川·成都外國語學(xué)校）Happinessisnotawarmphone,accordingtoanewstudyexploringthelinkbetweenyounglifesatisfactionandscreentime.ThestudywasledbyprofessorofpsychologyJeanM.TwengeatSanDiegoStateUniversity(SDSU).Toresearchthislink,Twenge,alongwithcolleaguesGabrielleMartinatSDSUandW.KeithCampbellattheUniversityofGeorgia,dealtwithdatafromtheMonitoringtheFuture(MtF)study,anationallyrepresentativesurveyofmorethanamillionU.S.8th,10th,and12thgraders.ThesurveyaskedstudentsquestionsabouthowoftentheyspenttimeontheirPhones,tabletsandputers,aswellasquestionsabouttheirfacetofacesocialinteractionsandtheiroverallhappiness.Onaveragefoundthatteenswhospentmoretimeinfrontofscreendevices—playingputergames,usingsocialmedia,textingandvideochatting—werelesshappythanthosewhoinvestedmoretimeinnonscreenactivitieslikesports,readingnewspapersandmagazines,andfacetofacesocialinteractions."Thekeytodigitalmediauseandhappinessislimiteduse,"Twengesaid."Aimtospendnomorethantwohoursadayondigitalmedia,andtrytoincreasetheamountoftimeyouspendseeingfriendsfacetofaceandexercising—twoactivitiesreliablylinkedtogreaterhappiness."Lookingathistoricaltrendsfromthesameagegroupssincethe1990s,it'seasytofindthattheincreaseofscreendevicesovertimehappenedatthesametimeasageneraldropoffinreportedhappinessinU.S.teens.Specifically,youngpeopledlifesatisfactionandhappinessdeclinedsharplyafter2012.That'stheyearwhenthepercentageofAmericanswhoownedasmartphoneroseabove50percent.Byfarthelargestchangeinteens'livesbetween2012and2016wastheincreaseintheamountoftimetheyspentondigitalmedia,andthefollowingdeclineininpersonsocialactivitiesandsleep.（1）第一段：發(fā)現(xiàn)內(nèi)容（幸福不是溫暖的）（2）第二段：實驗過程（3）第三段：實驗結(jié)果（玩不幸福）（4）第四段：實驗結(jié)論（5）第五段：歷史、未來1．WhichmethoddidTwenge'steamuseforthestudy?A．Calculatingstudents'happiness.B．Askingstudentscertainquestions.C．Analyzingdatafromasurvey.D．Doingexperimentsonscreentime.【解析】C，注意不要選B，實驗的邏輯是：通過問問題進行調(diào)查→得到數(shù)據(jù)→分析數(shù)據(jù)2．Howdoestheauthordevelopthefindingofthestudyinparagraph3?A．Bymakingaparison.
