+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。eg.1.Iwontforgetthedatewhen(onwhich)Iwasborn.2.Thisistheroomwhere(inwhich)Ilived.=ThisistheroomwhichIlivedin.3.Idontknowthereasonwhy(forwhich)hehaventcometoday.4.Tomstillremembersthedayswhen(inwhich)theylivedinTianjin.,考点四：关系代词前介词的确定,思考？,是否所有的介词+关系代词都能用关系副词代替?,Thepainting(_Ilooked)waspaintedbyme.,atwhich,Thebook(_Iheard)waswrittentwentyyearsago.,aboutwhich,Thepen(_shewrotethatbook)cannowbeseeninamuseum.,withwhich,Kunmingisabeautifulplace_(flowersareseenalltheyearround).,where/inwhich,Iwillneverforgottheday_Ifirstmetyouontheship.,onwhich/when,duringwhich,Thefilm(_Ifellasleep)wasveryboring.,结论：只有当介词+关系代词充当地点状语、时间状语或原因状语时，才能用关系副词代替。,五.注意定语从句的主谓一致性关系代词在定语从句中作主语时，从句的谓语必须与先行词保持人称和数的一致。例如：TomisoneoftheboyswhoarefromtheUSA.TomistheonlyoneofthetheboyswhoisfromtheUSA.,六.保持主句的完整性并避免从句成分的重叠,1.在定语从句中，不管出现任何情况，主句的结构必须完整，即主句必须有主语和谓语，缺一不可，否则，整个主从复合句就无法成立。试比较：,（1）Isthisfactory_wevisitedlastweek?（2）Isthisthefactory_wevisitedlastweek?A.whichB.whereC.whatD.theone,分析：第一题缺少表语，只有填D项才能保持主句的完整性，而其他的选项均为干扰项。第二题主句本身完整，应填的关系代词在从句中作visited的宾语，故应选A项。,Correctthesentences:,1.Imusingthepenwhichheboughtityesterday.2.Isthatfactorywhichyourfatheronceworkedin?3.ThemanwhomIspokeisfromCanada.4.July1,1999isthedaywhenwellneverforget.,(去掉),theone,_,to,_,which,5.Thestudentsandthingswhichyouspokeofareknowntous.,_,that,5.Einsteinissuchagreatscientistthatwemustlearnfrom.6.ThestudentwhosbookIhadborroweddidntcometoschooltoday.7.Whoistheworkerwhotooksomepicturesofthefactory.8.Itistheoneofthebestfilmswhichhavebeenshownrecently.9.ThethirdplacewhichwearegoingtovisitisHangzhou10.Whichisknowntoall,manysatellitearegoingaroundinthesky.,_,as,_,Whose,that,_,that,_,_,that,_,As,练习题,1、All_isusefultousisgood.,A、whichB、whatC、thatD、whether,C,2、Isthisfactory_wevisitedlastweek.,A、whereB、thatC、whichD、theone,D,3、Shewillneverforgettheday_shespentinBeijing.,A、whenB、whatC、whichD、why,C,4、Thisistheschool_myfatherworked20yearsago.,A、thatB、whenC、whichD、where,D,5、Thisistheveryfactory_wevisitedlastyear.,A、thatB、whichC、whatD、theone,A,6、Thetextisoneofthemostinterestingstories_learntinthepastthreedays.,A、thathaveB、thathavebeenC、whichhasD、whichhasbeen,B,7、Thecollegewonttakeanyone_eyesightisweak.,A、whoB、whoseC、ofwhomD、which,B,8、Letmethinkofapropersituation_thissentencecanbeused.,A、whereB、thatC、ofwhomD、which,A,9、Theman_youaretalkingisinthenextroom.,A、towhomB、aboutwhomC、aboutwhoD、whom,B,10、Thisisthelastfactory_heusedtoworkat,manyworkersof_stillhaveagoodrelationshi
