Unit 5 Music 语法介词+关系代词的定语从句

Unit5Music,Grammar介词+whom/which的定语从句,定语从句,什么是定语从句？用来修饰名词或代词的从句叫定语从句。被定语从句所修饰的名词或代词叫先行词（antecedent）。定语从句一般是由关系代词或关系副词来引导的。相当于名词和形容词的作用。当关系代词在定语从句中充当介词的宾语时，我们用“介词+关系代词(whom/which)”来引导定语从句。若先行词为人，用“介词+whom”;若先行词为物，用“介词+which”。,forward,关系词,关系代词whichthatwhowhomwhose,分为两类,关系副词whenwherewhy,3.Thebridge_theybuiltin1987destroyedintheearthquake.,Fillintheblankswithwho,whom,that,which,whose,when,where,why,1.Theearthquake_hitthecityin1906wasthebiggestinAmericanhistory.,2.Wedontknowthenumberofpeople_losttheirhomesin1906earthquake,that/which,that/who,which/that,6.Harryistheboy_motherisourmathsteacher.,4.Ahouse_isbuiltonsandmayfalldowninaearthquake.,5.Luckilynoneofthepeople_Iknowwerekilledintheearthquake.,which/that,who/whom/that,whose,9.Thisisreaon_Iamlateforyourclass.,7.Iwillneverforgettheday_mybikewasstolen.,8.Thisistheplace_helives.,when,where,why,Thisistheplace_helivesin.,思考：,Thisistheplace_helives.,where,which,return,Thisistheplace_helives.,inwhich,介词的确定,1.根据先行词与介词的搭配习惯来确定。(1)Thestudentdidntgivethereasonforwhichshewaslatefortheclass.(2)Shewillneverforgetthedaysinwhichsheworkedwithherfriends.(3)Sheworkedinaplaceinwhichthereweremanyyounggirlslikedher.,forwhich=why,inwhich=when,inwhich=where,(2)Hestillrememberstheexactdayonwhich(=when)hisbikewasstolen.(3)Shedidnttellhimthereasonforwhich(=why)shehadntattendedthemeetingontime.,2.根据定语从句中的谓语动词或形容词确定介词，改接词语动词搭配，构成固定的动词短语。(1)Themanwithsunglassesisthemanforwhomtheyarewaiting.(2)HeisthemantowhomIusuallyturnforhelp.(3)Theplanaboutwhichtheyaretalkingwillbecarriedoutnextweek.,turntosb向某人求助,waitforsb等待某人,talkaboutsth谈论.,(1)Themanwithsunglassesisthemanforwhomtheyarewaiting.Themanwithsunglassesisthemanwhom/who/thattheyarewaitingfor.(2)HeisthemantowhomIusuallyturnforhelp.Heisthemanwhom/who/thatIusuallyturntoforhelp.(3)Theplanaboutwhichtheyaretalkingwillbecarriedoutnextweek.,3.根据句子的意思确定介词。有些句子，先行词完全一样，定语从句中动词也不是固定的动词短语。这是需要根据句子所表达的意思选用不同的介词。(1)Thisisthesingerwithwhomtheactresswilldosomevoluntarywork.(2)Thisisthesingeraboutwhomthefansaretalking.,“介词+which/whom”的替换,1.当先行词为表示时间，地点的名词或名词短语及名词reason时，介词in,on,at,for等与关系词which一定引导定语从句，此时可用相关的关系副词when,where,why等替换。(1)Beijingisthecityinwhich(=where)theheavyhaze(大雾)hasoftentakenpalcerecently.,2.the+名词+of+关系代词引导的定语从句时，可用“of+关系代词+the+名词或whose+名词替换。Theyhaveboughtanapartementrecentlythebedroo
