“介词+关系代词”引导的定语从句

一、关系代词在定语从句中作介词的宾语关系代词指人介词+whom关系代词指物介词+whicha.Themanbywhomthethiefwascaughtwasagoodpoliceman.b.ThisisthereasonforwhichIwaspraisedbymychemistryteacher.二、“介词＋关系代词”结构中介词的选用介词的选择可以总结为：“一先、二动、三意义、四特殊”。1.一先，即先看先行词，从先行词入手。介词往往和先行词构成固定搭配。①Languageisoneofmeans

bywhichpeoplecancommunicateideasandemotionswitheachother.(bymeans为固定搭配，表示“通过某种手段”。)②Whatisatissueistheextent

towhichexamresultscanreflectastudent'sability.(totheextent为固定搭配，表示“在某种程度上”。)2.二动，即看从句中的谓语动词结构。根据从句中谓语动词的搭配选择合适的介词。①TherecomesTom,forwhomIhavebeenwaitingforanhour.(waitforsb等候某人)汤姆总算来了，我等了他一个小时了。②Doyouknowthegirltowhomourteacherwastalking(talktosb和某人交谈)你认识那个刚才和我们老师交谈的女孩吗？③Mymothermissedherbestfriendwithwhomsheworkedinheryouth.(workwithsb和某人一起工作)母亲很想念她最好的朋友，在年少时期，她们曾经一起工作过。像lookafter,dependon,payattentionto,takecareof等固定动词短语，在定语从句中一般不宜将介词与动词分开。①ThisisthewatchwhichIamlookingfor.(T)ThisisthewatchforwhichIamlooking.(F)②

ThisistheoldladywhomHaroldhastakencareof.(T)

ThisistheoldladyofwhomHaroldhastakencare.(F)补充拓展：3.三意义：通过判断主句表达的全部意义来确定合适的介词。①Hewaseducatedatalocalhighschool，afterwhichhewentontoBeijingUniversity.

他在当地的一所高中上学，之后他继续在北京大学学习。②Ericreceivedtrainingincomputerforoneyear,afterwhichheeasilyfoundajobinabigcompany.艾瑞克接受了为期一年的电脑培训，之后他顺利在一家大公司找到了工作。4.四特殊：介词of常用于“表示部分的词语＋of＋关系代词”结构。表示部分的词语常见的有：不定代词all,both,none,neither,either,some,any；数词(含基数词、序数词、分数和百分数)；数词＋名词；the＋最高级/比较级，以及表示数目或数量的词语many,most,few,several,enough,half,aquarter。①Therearetenbooksonthereadinglist,threeofwhicharemyfavourite.阅读书单上有10本书，其中3本是我最喜欢的。②Thefactoryproduceshalfamillionpairsofshoeseveryyear,80%ofwhicharesoldabroad.这家工厂每年生产50万双鞋子，其中的80%销往国外。③Therearetworoomsfacingthesouth,thesmallerofwhichismystudyroom.有两个朝南的房间，其中较小的那个是我的书房。2Connectthesentenceswithapreposition+whom/which.1.TheZhuangisanethnicgroup.ItspopulationisthelargestofallethnicgroupsinChina.TheZhuangisanethnicgroupofwhichthepopulationisthelargestofallethnicgroupsinChina.2.Guangxiisaprovince.TheLongjiRiceTerracesarelocatedinit.GuangxiisaprovinceinwhichtheLongjiRiceTerracesarelocated.3.Iwanttovisitthisculturallandscape.ThetitleofUNESCOWorldHeritageSitewasgiventoitin2016.IwanttovisitthisculturallandscapetowhichthetitleofUNESCOWorldHeritageSitewasgivenin2016.4.Heisanexpertonriceplanting.ThelocalZhuangpeoplehavelearntalotfromhim.HeisanexpertonriceplantingfromwhomthelocalZhuangpeoplehavelearntalot.3Completethepassagewithapreposition+whom/which.Amongthemanybeautifultreasurespeoplecanreceivefromnaturearenaturaldyes.Themostcommonnaturalsource1__________naturaldyescomeisplants.Materialsformakingnaturaldyescanoftenbefoundingardens2_________colourfulflowersareplanted.Othernaturaldyesaremadefrominsects,seacreaturesandmineralcompounds.fromwhichinwhichNaturaldyesarenowreturningtopopularity,especiallywithartistsandcraftspeople.Thereasons3___________theyprefernaturaldyesarethatthecoloursarebrighterandcanbekeptlonger.Naturaldyesarealsobecomingmorepopularwithconsumers4_________caringfortheenvironmentisapriority.Moreandmorepeoplefeelthatbyusingnaturaldyes,wecanremindourselvesofnature’sbeautyandprotectthenaturalworld.forwhomforwhichGeographicalfeatures4Readthedescriptionsandmatchthemwiththepictures.LocatedoffthecoastofAustralia,theGreatBarrierReefisthebiggeststructuremadebylivingorganisms.YoucanexploretheGreatBarrierReefbyvisitinganunderwaterobservatory.PartoftheColoradoRiverBasin,theGrandCanyonisavalleythatisalmosttwokilometresdeep.TouristscanstandonanarrowglassplatformcalledtheSkywalktoseetheGrandCanyon.VictoriaFallsisthelargestwaterfallintheworld.Thelocalpeoplecallit“thesmokethatthunders”.TheVictoriaFallsBridgeconnectsthecountriesZimbabweandZambia.TheEnglishChannelseparatesEnglandfromFrance.ThesetwocountriesarejoinedbytheChannelTunnel,arailtunnelwithalengthofabout50kilometres,mostofwhichisunderthesea.reefchanneltunnelseabasincanyonvalleywaterfallWordsandexpressionsforgeographicalfeatureslocatedoffthecoast……kilometresdeepseparate…from…withalengthof…MatchthewordsandexpressionstotheirChinesemeanings.盆地海峡瀑布大堡礁山谷海底隧道峡谷waterfallchannelChannelTunnelvalleycanyonbasintheGreatBarrierReef5CompletetheemailwiththewordsinboldinActivity4.From:Emma
