法关系副词和关系代词的选择是根据先行词在定语从句中作的成分。若是做状语，则用关系副词或“介词+which”若是作主语或宾语，则用关系代词。例如：,.,62,Iwillneverforgetthedays(that/which)IspentwithmyteacherIwillneverforgetthedayswhenIplayedwithyou,.,63,Thefactory(that/which)wevisitedyesterdaywasbuiltlastyearThefactorywhereheworkswasbuiltlastyear,.,64,Thisisthereason(that/which)shegavemefordoingitDoyouknowthereasonswhyhecamelate?,.,65,但要注意在以下8种情况下,指物时用that不用which,who,注意！,.,66,1.先行词是all,any,everything,anything,nothing,something,much,little,few,none,theone等时,Thereismuchthatshouldbeused.Youcantakeanyseatthatisfree.,.,67,2.先行词被all,any,no,only,little,much,very,every,some,few,none等修饰时,Ihavereadallthebooks(that)yougaveme.Everydictionarythatourlibraryboughtisgood.,.,68,3.先行词被序数词或最高级修饰时。,ThisisthemostinterestingbookthatIhaveeverread.ThefirstlessonthatIlearnedwillneverbeforgotten.,.,69,4.先行词被theonly,thevery,thesame,thelast修饰时。,Thisistheverybookthatbelongstohim.TheGreatWallisthelastplacethatMr.SmithisgoingtovisitbeforeheleavesBeijing.,.,70,5.在以which,who作主语的特殊疑问句中的定语从句中,Whoisthemanthatisreadingabookthere?Whichisthemagazinethatyouborrowedfromthereadingroom?,.,71,6.当先行词既有表示人又有表示物的词时,Wetalkedofthethingsandpersonsthatweremembered.,.,72,7.当先行词在定语从句中做表语时,无论先行词是人还是物,Chinaisnolongerthecountrythatshewas.,.,73,8.主句以therebe开头时,ThereislittlethatIcandotomakeupforthelosttime.,.,74,(1)关系代词在限制性定语从句中紧跟介词作宾语（介词提前）。Therearemanytrees_theycanhavearest.Thisisthering_shespent1000dollars.,2、只用which不用that的情况,(2)在非限制性定语从句中。Football,_isaverypopulargame,isplayedallovertheworld.,underwhich,onwhich,which,.,75,3.表所有关系及整体中的一部分或全部时，用介词of,有时可用whose转换。1)Impaintingahouse,theroof_isround.,Impaintingahouse_isround.,2)Theyliveinahouse,_windowsfacesouth.,Theyliveinahouse,thewindows_facesouth.,ofwhich,whose,ofwhich,whoseroof,.,76,不用that的场合如下：1）非限制性定语从句中Lastnight,Isawaverygoodfilm,whichwasabouttheLongMarch.2）介词放在关系代词之前时ThisisthemanfromwhomIlearntthenews3）句中出现了that，或先行词是that时IhavefoundthatwhichIwaslookingfor.,.,77,二、只用who的情况,One_hasnothingtofeardarestotellthetruth.Theones_laughatthedisabledarenotgoodstudents.Anyone_failstofinishthetaskshouldbepunished.Those_wanttogotoTheGreatWallsighuphere.,who,who,who,who,先行词是one,ones,anyone,those时用who.,.,78,限制性定语从句和非限制性定语从句,限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；,非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。,(1)Thisisthehousewhichweboughtlastmonth.,（限制性）,(2)Thehouse,whichweboughtlastmonth,isverynice.,(非限制性）,(3)CharlesSmith,whowasmyformerteacher,retiredlastyear.,(非限制性）,.,79,定语从句必须注意的特殊例子1.先行词为situation,case,stage,point,position关系词要用where,inwhicheg.Canyouimagingthesituationwhere/inwhichyoucanusetheword.2.先行词为way,关系词要用that,inwhich或省略eg.Doyouknowtheway(that/inwhich/-)heworkedtheproblem.,.,80,3.定语从句的必须注意的两个句型。Isthisschooltheonewevisitedthatyear?Isthistheschoolthatwevisitedthatyear?Heisoneofthestudentswhoarefromthesouth.Heisthe(only)oneofthestudentswhoisfromthesouth.,.,81,修饰人时关系代词that和who,whom的区分。当主句中的主语是who时，只能用that。eg.Whoisthegirlthatisstandingoverthere?在非限制性定语从句中以及介词后面时只能用who或者whom。eg.Ihaveason,whoisreallylovelyandinteresting.Thereare40studentsintheclass,mostofwhomareboys.关系代词whose既能修饰人，也能修饰物，在定语从句中充当定语，修饰先行词。eg.SheisthegirlwhoseEnglishsoundsverybeautiful.Maryhasaverygooddog,whosehairturnsoutwhiteandblack.,.,82,关系副词when,where,why的用法以及与关系代词的区分。关系副词在定语从句当中只能充当状语，当一个句子能够完整地表达一个意思时，我们就可以给这个句子加上特定的关系副词。eg.IwontforgetthetimewhenIgotmarried.Haveyoustillrememberthedayswhenwestayedtogether?Thisistheplacewherewehadagoodtime.IsthisthehousewhereMrSmithlives?Idontknowthereasonwhyhewontjoinus.Doyouknowthereasonwhyhedidntcometosweeptheclassroom?,.,83,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。eg.1.Iwontforgetthedatewhen(onwhich)Iwasborn.2.Thisistheroomwhere(inwhich)Ilived.=ThisistheroomwhichIlivedin.3.Idontknowthereasonwhy(forwhich)hehaventcometoday.4.Tomstillremembersthedayswhen(inwhich)theylivedinTianjin.,.,84,1.whose既可引导限制性定语从句，又可引导非限制性定语从句。Myunclewhoseofficewehavejustpassed,isalawyer.OncetherewasawisekingwhosenamewasAlfred.2.whose代指“的”，既可以指人，也可以指物。Lookatthebuilding,whoseroofiswhite.Thegirllivesinthehouse,whosewindowsfacesouth.,whose在定语从句中的用法,.,85,关系副词when,where和关系代词that,which的区分。同样是修饰一个地点，有时使用where，有时使用that/which；同样是修饰一个时间，有时使用when，有时使用that/which。这主要看两点：一是定语从句是否完整；二是定语从句中的谓语动词是否是一个及物动词。请比较以下句子：Thisistheparkthatwevisitedlastyear.Thisistheparkwhereweheldabirthdayparty.Shewontforgetthedaysthatshespentontheisland.Shewontforgetthedayswhentheystayedtogether.Thatsthedatewhenwewenttothecollege.Thatsthedatethatshewontforgetforever.Ilikethetimewhenwelivedtogether.Ilikethetimethatwehadtogether.,.,86,注意:1.介词关系代词引导的定语从句,关键是判断介词的选择看从句谓语部分缺少什么介词(习惯搭配)先行词放在从句中需不需要添介词通过整个句子整体含义来判断2.whom,which作介词宾语时,介词一般可放在which之前,也可放在从句原来的位置上,在含有介词的动词固定词组中,介词只能放在原来的位置上.,.,87,关系代词和关系副词如何区别？,1.取决于从句中的谓语动词。不及物动词后面无宾语，就必须用关系副词或介词+关系代词；而及物动词后接宾语，则要求用关系代词。2.要看他们在从句中作什么成份而定。或者说，假如把先行词放到从句中是作主语、宾语还是状语而定。1）ThisisthemountainvillagewhereIstayedlastyear.2）IllneverforgetthedayswhenIworkedtogetherwithyou.3）Illneverforgetthedays(which)Ispentinthecountryside
