资源描述

Preposition+which/+whomATTIBUTIVE:FOLLOWME!定语从句介词+which/whom引导的定语从句用于正式场合。在这一结构中,关系代词which/whom做介词的宾语。•当先行词是人时,用介词+whom引导定语从句,例如:Theymaystartasagroupofhigh-schoolstudents,forwhompractisingtheirmusicinsomeone’shouseisthefirststeptofame.•当先行词是物时,用介词+which引导定语从句,而且只能加which,不能加that,例如:Theyproducedanewrecordin1996,withwhichtheycelebratedtheirformertimeasarealband.关系副词when,where,why和介词+which之间的关系关系副词when,where,why可以用适当的介词+which来替代。如:when=in/on/at…+which,where=in/on/at…+which,why=for+which。介词的位置非常灵活,有时放在关系代词之前,有时放在动词之后。1.Iwon’tforgetthedatewhen(onwhich)Iwasborn.2.Thisistheroomwhere(inwhich)Ilived.=ThisistheroomwhichIlivedin.3.Idon’tknowthereasonwhy(forwhich)hehaven’tcometoday.4.Tomstillremembersthedayswhen(inwhich)theylivedinTianjin.注意:介词+which(指物),不可省介词+whom(指人),不可省介词后不用who、thatThecitywhichshelivesinisfaraway.Themanwhomyouspoketoisourheadmaster.Thefarmonwhichweworkedtenyearsagoisbeautiful.Thisisthetreeunderwhichweusedtoplaygames.Hangzhouistheplacewhere/towhichIwentlastsummer.Irememberthedaywhen/onwhichmyfatherdied.Iwasonlytenyearsoldatthattime.1.介词的确定方法•Themoneywithwhichyouweretobuydogfoodisgone.•Hewon’tforgetthedayonwhichhefailedintheexam.①根据先行词来确定•Wethoughtyouwereapersonfromwhomwecouldexpectgooddecisions.•TheWestLake,forwhichHangzhouisfamous,isabeautifulplace.②根据定语从句中的谓语动词或形容词确定Air,withoutwhichmancan’tlive,isreallyimportant.③根据定语从句所表达的意义来确定Thepenwithwhichheiswritingnowwasboughtyesterday.2.介词的位置①一般情况下,介词放在关系代词which和whom之前,也可放在动词后。•②固定搭配的动词短语中的介词一般不能提前.•常见的这类动词短语有:lookfor/after/forwardto、•carefor、takecareof、hearof/about/from,等.•ThisistherightplaceI’mlookingfor.•Thegirlwhomheislookingafterishissister.介词﹢关系代词引导的定语从句,关键是判断介词的选择,方法一是看从句谓语部分缺少什么介词(习惯搭配),再则可以通过整个句子整体含义来判断,结合生活实际来判断.Tips1.Doyoulikethebookonwhichshespent$10?2.Doyoulikethebookforwhichshepaid$10?3.Doyoulikethebookformwhichshelearnedalot?4.Doyoulikethebookaboutwhichsheoftentalks?介词+关系代词的使用5.ThemantowhomIspokeonthephonelastnightisverygoodatwriting.6.Glasses,withoutwhichIcan’tseeclearly,arereallyimportantforme.7.Chinaisabeautifulcountry,ofwhichweareproud.8.Doyourememberthedayonwhichyoujoinedourclub?1.Theman___________Ishookhandsjustnowismydaughter’sEnglishteacher.2.Adesertisagreatplain_________nothingwillgrow.3.Hewastheman___________roomthethiefhadstolenthebag.4.Thisismypairofglasses,______________Icannotseeclearly.withwhominwhichfromwhosewithoutwhichThisistheteacherwhosedaughterisafamousdoctor.=Thisistheteacherthedaughterofwhomisafamousdoctor.1.名词+介词+关系代词Wehavethreeforeignteachers,twoofwhomarefromCanada.2.数词+介词+关系代词(含基数词、序数词、分数和百分数)3.代词+介词+关系代词(代词有all、both、-----none、neither、either、some、any等)Theoldwomanhastwosons,bothofwhomareteachers.4.形容词最高级+介词+关系代词Chinahasthousandsofislands,thelargestofwhichisTaiwanIsland.5.介词+关系代词+名词Hespentfouryearsincollege,duringwhichtimehestudiedmedicine.5.Thegirl_______________hespokemadenoanswer.6.Thefactoryproduceshalfamillionpairsofshoeseveryyear,80%_________aresoldabroad.7.Theyaskedmealotofquestions,many___________Icouldn’tanswer.8.Twomen,________________Ihadeverseenbefore,cameintomyoffice.我以前从未见过他们neitherofwhomtowhomofwhichofwhich9.Hegothisfirstsalary,___________hegavetohisparents.其中一半10.Ourcountryhasmanyislands,____________________isTaiwan.其中最大的11.Thejourneyaroundtheworldtooktheoldsailorninemonths,________thesailingtimewas226days.thelargestofwhichhalfofwhichofwhich介词加关系代词的基本用法•Theman__________youshookhandsjustnowisourheadmaster.•Theroom__________myfamilyliveusedtobeagarage.•Didyoufindthepen_________Iwrotejustnow?•Didyoufindthepaper________Iwrotemyletter?•Didyoufindthecomposition______Iwrotejustnow?withwhominwhichwithwhichonwhichwhich•Thefarmweworkedtenyearsagoisn’twhatitusedtobe.•Heisthemanyoucanturnforhelp.•Thisisthetreeweusedtoplaygames.onwhichtowhomunderwhichonthefarm在农场turntosb.forhelp向某人求助underthetree在树下Thesungivesusheatandlight,_______________wecan’tlive.Thestudent___________weweretalkingjustnowisthebeststudentinourclass.I’llneverforgettheday__________shesaidgoodbyetome.Whocangivemethereason________hehasn’tturnedupyet?withoutwhichaboutwhomonwhichforwhich1.Theteacher__________IlearntmostwasMrsZhu.2.Thisisthehouse__________LuXunoncelived.3.Thereason___________IcamehereisthatIwanttogetyourhelp.4.Thefellow________Ispokemadenoanswer.5.TheWestLake,___________Hangzhouisfamous,isabeautifulplace.fromwhominwhichforwhichtowhomforwhich1.Doyouknowwholivesinthebuilding______thereisawell?A.infrontofitB.infrontofwhoseC.infrontofwhichD.infrontwhich2.I’llneverforgettheday____IjoinedtheLeague.A.onwhichB.inwhichC.whichD.atwhich3.Thewoman_____mybrotherspokejustnowismyteacher.A.whoB.towhomC.towhoDwhomCAB4.Jeannewasheroldfriend,____sheborrowedanecklace.A.fromwhoB.fromwhomC.tothatD.towhom5.Hisglasses,_____hewaslikeablindman,felltothegroundandbrokeitsleg.A.whichB.withwhichC.withoutwhichD.that6.sheisateacherofmuchknowledge,_____muchcanbelearned.A.whoB.thatC.fromwhichD.fromwhomBCD7.Hebuiltatelescope___hecouldstudytheskies.A.inwhichB.withthatC.throughwhichD.byit8.Doyouknowthereason____hewaslate?A.thatB.whichC.forwhatD.forwhich9.Ihaveboughttwobal
