①当先行词为all,much,little,few,none,something,anything,everything,nothing等不定代词时，如：

a.Allthatcanbedonehasbeendone.b.Iamsureshehassomething(that)youcanborrow.c.Thereislittle(that)theenemycandobesidessurrender.②

先行词被all,every,no,some,any,little,much修饰时：I’vereadallthebooks(that)yougaveme.定语从句“从全错到全对”专题教学幻灯考点二：that和which的选择③先行词是序数词或形容词最高级修饰时。Thisisthebestbook(that)I’veeverread.Thisisthefirstcomposition(that)hehaswritteninEnglish.④先行词被theonly,thevery,thelast修饰时。Thatwhitefloweristheonlyone(that)Ireallylike.Thisistheverybook(that)Iwanttofind.⑤

当有两个或两个以上分别表示人和物的先行词时，这个定语从句要用that而不用who(whom)和which引导。如：Hetalkedabouttheteachersandschools

（that）hehadvisited.定语从句“从全错到全对”专题教学幻灯⑥先行词是疑问词who,which,what

时，定语从句用that而不用who,(whom)和which引导。考点二：that和which的选择Whoisthepersonthatisstandingatthegate?Whichofusthatknowssomethingaboutphysicsdoesnotknowthis?Whatthatisonthetablebelongstome?⑦

当关系代词在从句中作表语时：Maryisnolongerthegirl(that)sheusedtobe.Chinaisnolongerthecountrythatitusedtobe.

定语从句“从全错到全对”专题教学幻灯Which可以引导非限定性定语从句，可用于介词后，其先行词可是一个词,也可是整个主句或主句的某一部分。

1Sheheardaterriblenoise,______broughtherheartintohermouth.A.itB.whichC.thisD.that2.Theweatherturnedouttobegood,___wasmorethanwecouldexpect.A.whatB.whichC.thatD.it考点二：that和which的选择（2）只用which的情况BB定语从句“从全错到全对”专题教学幻灯考点三：as与which引导的定语从句※对这两个词作如下归纳：1、如果定语放主句后，即引用as也可以用which.Hefailedtotheexam,as(=which)isnatural.Sheseemsascientist,as(=which)infactsheis.Grammarisnotadeadrule,which(=as)Ihavesaidbefore.2、如果从句在主句前，这时要用as而不用which引导定语从句。如：

Asweallknow,hisparentswerekilledinthewar.Asweallknow,

theearthisround.定语从句“从全错到全对”专题教学幻灯3.用于thesame…as…,such…as…，as…as…,so…as…中，一般用as。e.g.Suchbooks

asyoutellme

areinteresting.ThisisthesamebookasIlentyouyesterday.4.as代表前面主句意思时，有“正如…”之意，而which没有此意思，从句中的动词常是expect,know,see,think,want,suppose等。Hewonthematch,aswehadexpected.Heagreedtotheplan,aswastobeexpected.Thepolicewerelookingforhim,ashethought.考点三：as与which引导的定语从句Hereissobigastoneasnomancanlift.定语从句“从全错到全对”专题教学幻灯5.as在从句中作主语时，后面常接行为动词的被动语态，如beknown，besaid，bereported等，如从句中行为动词是主动语态，一般要用which作主语。e.g.Shehasbeenlateagain,aswasexpected.Tomhasmadegreatprogress,whichmadeushappy.6.如果从句的内容对主句内容起着消极作用，或者说导致的结果，则用which.a.Hecheatedhisfriendofmachmoney,whichwasverydisgraceful.b.Hecamebacklate,whichmadehismotherworried.考点三：as与which引导的定语从句定语从句“从全错到全对”专题教学幻灯考点四：关系代词前介词的确定如何选定介词:1.根据从句中动词与先行词的逻辑关系，请体会：e.g.Isthatthenewspaper

forwhichyouoftenwritearticles?2.根据从句中动词或形容词的习惯搭配，如：e.g.CanyouexplaintomehowtousetheseidiomsaboutwhichI’msure.3.根据先行词与介词的搭配习惯，请体会：e.g.1949wastheyearinwhichtheP.R.C.wasfounded.定语从句“从全错到全对”专题教学幻灯4.非限制性定与从句中，要表示先行词的一部分时，可用“数词/代词+of+关系代词”的结构，如：e.g.Thereare50studentsinourclass,two-thirdsofwhomhavebeentoBeijing.5.Whose从句可转换为“

of+关系代词”型，如：e.g.Theyliveinahouse,whosedooropenstothesouth.

Theylivedinahouse,ofwhichthedooropenstothesouth.Theylivedinahouse,thedoorofwhichopenstothesouth.考点四：关系代词前介词的确定定语从句“从全错到全对”专题教学幻灯关系副词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.Iwon’tforgetthedate

when(onwhich)Iwasborn.2.Thisistheroom

where(inwhich)Ilived.=Thisistheroom

whichIlivedin.3.Idon’tknowthereason

why(forwhich)hehaven’tcometoday.4.Tomstillremembersthedays

when(inwhich)theylivedinTianjin.考点四：关系代词前介词的确定定语从句“从全错到全对”专题教学幻灯思考？是否所有的介词+关系代词都能用关系副词代替?Thepainting(__________Ilooked)waspaintedbyme.atwhichThebook(______________Iheard)waswrittentwentyyearsago.aboutwhichThepen(____________shewrotethatbook)cannowbeseeninamuseum.withwhichKunmingisabeautifulplace_____________(flowersareseenalltheyearround).where/inwhichIwillneverforgottheday_____________Ifirstmetyouontheship.onwhich/whenduringwhichThefilm(_____________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。定语从句“从全错到全对”专题教学幻灯Correctthesentences:1.I’musin
