Unit9语法导学案:定语从句专题讲解一、基本概念:在复合句中,修饰某一名词或代词的从句叫定语从句。Doyouknowthemanwhospokeatthemeetingjustnow?Thatisthehousewherehelivedtenyearsago.定语从句所修饰的词叫先行词;定语从句一般用关系代词或关系副词来引导,关系词放在先行词与定语从句之间起连接作用,同时又作从句中的一个成分。引导定语从句的关系代词有:that,who,whom,whose,which,as关系副词有:when,where,why.二、定语从句的关系词引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that,which,who(宾格whom,所有格whose)等,关系副词包括where,when,why等。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。定语从句的谓语动词由先行词来决定。三、定语从句的分类根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。四、关系代词的用法关系代词指代在定语从句中的作用that既指人,也指物主语、宾语which指物(相当于that)主语、宾语who指人(相当于that)主语whom指人宾语whose既指人,也指物定语1.that既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如:Marylikesmusicthatisquietandgentle.玛丽喜欢轻柔的音乐。(that作主语)Thecoat(that)Iputonthedeskisblue.我放在桌子上的那件外套是蓝色的。(that作宾语)2.which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如:Thebuildingwhichstandsnearthetrainstationisasupermarket.位于火车站附近的那座大楼是一家超市。(作主语)Thefilm(which)wesawlastnightwaswonderful.我们昨天晚上看的那部电影很好看。(作宾语)3.who,whom用于指人,who用作主语,whom用作宾语。在口语中,有时可用who代替whom,也可省略。例如:ThegirlwhooftenhelpsmewithmyEnglishisfromEngland.经常在英语方面帮助我的那个女孩是英国人。(作主语)Whoistheteacher(whom)LiMingistalkingto?正在与李明谈话的老师是谁?(作宾语)注意:(1)当定语从句中含有介词,介词放在句末时,who,that,which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如:Thisisthehouseinwhichwelivedlastyear.这是我们去年居住的房子。PleasetellmefromwhomyouborrowedtheEnglishnovel.请告诉我你从谁那借的这本英文小说。(2)含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如:Thisisthepersonwhomyouarelookingfor.这就是你要找的那个人。(3)that作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如:Thecitythatshelivesinisveryfaraway.她居住的城市非常远。(4)关系词只能用that的情况:a.先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如:Hewasthefirstpersonthatpassedtheexam.他是第一个通过考试的人。b.被修饰的先行词为all,any,much,many,everything,anything,none,theone等不定代词时,只能用that,而不用which.例如:Isthereanythingthatyouwanttobuyintheshop?你在商店里有什么东西要买吗?c.先行词被theonly,thevery,thesame,thelast,little,few等词修饰时,只能用that,而不用which.例如:ThisisthesamebikethatIlost.这就是我丢的那辆自行车。d.先行词里同时含有人或物时,只能用that,而不用which.例如:IcanrememberwellthepersonsandsomepicturesthatIsawintheroom.我能清楚记得我在那个房间所见到的人和一些照片。e.以who或which引导的特殊疑问句,为避免重复,只能用that.例如:Whoisthegirlthatiscrying?正在哭泣的那个女孩是谁?f.主句是therebe结构,修饰主语的定语从句用that,而不用which.例如:ThereisabookonthedeskthatbelongstoTom.桌子上那本书是汤姆的。(5)关系词只能用which,而不用that的情况:a.先行词为that,those时,用which,而不用that.例如:What‘sthatwhichisunderthedesk?在桌子底下的那些东西是什么?b.关系代词前有介词时,一般用which,而不用that.例如:Thisistheroominwhichhelives.这是他居住的房间。c.引导非限制性定语从句,用which,而不用that.例如:Tomcameback,whichmadeushappy.汤姆回来了,这使我们很高兴。五、关系副词的用法(1)when指时间,其先行词表示时间,在句中作时间状语。它的先行词通常有:time,day,morning,night,week,year等例如:Thiswasthetimewhenhearrived.这是他到达的时间。(2)where指地点,其先行词表示地点,在句中作地点状语。它的先行词常有:place,spot,street,house,room,city,town,country等。例如:Thisisplacewhereheworks.这是他工作的地点。注意:先行词表示地点,不一定都用Where引导定语从句一般来说,英语学习者的脑海中会形成这样一个概念:在定语从句中,如果先行词是表示地点的名词(如place等),就用关系副词where引导定语从句。这种想法是错误的。如果定语从句不缺少主语或宾语,而是缺少地点状语,便用where来引导;如果定语从句不缺少状语,而是缺少主语或宾语,则要用关系代词(which或that)来引导,以补足定语从句中所缺失的主语或宾语如1.Inanhour,wecantraveltoplaces_____wouldhavetakenourancestorsdaystoreach.A.whereB.whenC.whichD.what2.Thisisthetown_____Iwantedtovisitmost.A.whereB.whenC.thatD.what3.Thisisthetown_____Iwasborn.A.whereB.whenC.whichD.what4.I’veneverbeentoBeijing,butitstheplace____.A.whereI’dliketovisitB.inwhichI’dliketovisitC.ImostwanttovisitD.thatIwanttovisititmost(3)why指原因,其先行词是原因,起原因状语作用。它的先行词只有reason。例如:Nobodyknowsthereasonwhyheisoftenlateforschool.没人知道他为什么上学总迟到。1这三个关系副词在意义上都相当于一定的介词+which结构:when=on(in,at,during......)+which;where=in(at,o......)+which;why=forwhich.例如:IwasinBeijingonthedaywhen(=onwhich)hearrived.Theofficewhere(=inwhich)heworksisonthethirdfloor.Thisisthechiefreasonwhy(=forwhich)wedidit.练习题I.单项填空1.-Doyouknowtheman______istalkingwithyourfather?-Yes,he‘sourheadmaster.A.heB.whoC.whichD.whom2.Isthistheriver_____Icanswim?A.whichB.inwhichC.thatD.theone3.Thisisthebesthotelinthecity_____Iknow.A.whereB.whichC.thatD.it4.Canyoulendmethedictionary______theotherday?A.thatyouboughtB.youboughtitC.thatyouboughtitD.whichyouboughtit5.Anyone______withwhatIsaidmayputupyouhands.A.whichagreesB.whoagreeC.whoagreesD.whichagree6.Mywatchisnottheonlything______ismissing.A.thatB.itC.whichwho7.Theman______coatisblackiswaitingatthegateA.who‘sB.whoseC.thatofwhich.8.Thegirl______isreadingunderthetree_____mysister.A.which;isB.whom;wasC.who;isD.who;was9.Iloveplaces______thepeoplearereallyfriendly.A.thatB.whichC.whereD.who10.Theworld______ismadeupofmatter.A.inthatweliveB.onwhichweliveC.whereweliveinD.weliveinⅡ、用适当的关系代词that,which,who,whom填空。1.Thefirstthing______youmustdoistohaveameal.2.April1stistheday_____iscalledAprilFool’sDayinthewest.3.Thefamily_____hadlosteverythinginabigfiregotmuchhelpfromtheirfriends.4.Thehouse_____weliveinisveryold.5.Didn’tyouseetheman______Italkedwithjustnow?Ⅲ、根据句意,在横线处填上恰当的关系代词。1.Whodrewthepicture________isworth60,000yuan?2.Theman________iswearingablueT-shirtisgoodatskating.3.Thisisastore________sellsallkindsofschoolthings.4.Thewoman________youtalkedtojustnowisourEnglishteacher.5.Thetown________wevisitedlasttimeismuchlargerthanbefore.6.Wesawthetree________wasfivehundredyearsold.7.Thecomp
