教学过程
由关系副词(when/where/why)引导的定语从句
关系副词可替代的先行词是时间、地点或理由的名词,如果在从句中作状语,此时要选择关系副词。
此时,关系副词=介词+关系代词
why=forwhich
where=in/at/on/...which(介词同先行词搭配)
when=during/on/in/...which(介词同先行词搭配)
考点一:
如何判定用关系代词还是用关系副词
1、定语从句中谓语动词为及物动词。
确定是否_主语和宾语都齐全__。
如__齐全__,证明从句中不缺主语和宾语,所以,用关系副词,即先行词在从句中作状语。
用什么关系副词看__先行词___。
例:
IwillneverforgetthedaywhenImetmyfavoritestar.
主句:
Iwillneverforgettheday。
我永远不会忘记那一天。
从句:
Imetmyfavoritestarontheday.我在那一天见到了我最喜欢的明星。
=IwillneverforgetthedayonwhichImetmyfavoritestar.
对比:
Iwillneverforgetthedayswhich/thatwespenttogether.
Iwillneverforgetthedays。
我永远不会忘记那些天。
Wespentthedaystogether.我们一起度过那些天。
(thedays在从句中作宾语)
Iwillneverforgetthedays(______Istayedwithyou).
JurassicParkisaboutapark______(averyrichmankeepsdifferentKindsofdinosaurs).
1958wastheyear______(Spielbergmadehisfirstrealfilm).
Pleasegivemethereason_____(youmadesuchagreatsuccess).
Morningisthebesttime______(youpractisereadingaloud).
Doyourememberthelake_____(youfirstmetyourgirlfriend.)
2、定语从句中谓语动词为不及物动词。
若从句无__主语__,则用__关系代词_;
若有主语,则用__关系副词___,即先行词在从句中作状语。
例1:
Thiswasthetimewhenhearrived.
解析:
Thiswasthetime.这就是那个时间。
Hearrivedatthetime.他在那个时间到达。
(thetime在从句作状语)
=Thiswasthetimeatwhichhearrived.
例2:
Thisisthefactorywhereheworks.
Thisisthefactory。
这就是那家工厂。
Heworksinthefactory.他在那家工厂上班。
(thefactory在从句中作状语)
=Thisisthefactoryinwhichheworks.
Thisisthefactorythatmyfatherbuiltlastyear.
主句:
从句:
Myfatherbuiltthefactorylastyear.我爸爸去年建了这家工厂(thefactory在从句中作宾语)
Yesterdaywewenttovisitthehouse______(thegreatwriterusedtolive).
Thehouse______(theybuiltin1987)stayedupintheearthquake.
Myfatherwasbornintheyear______(theSecondWorldWarbrokeout).
3、如定语从句中先行词是时间、地点名词,且谓语结构是被动结构,有主语,则用__关系副词__。
Kunmingisabeautifulplace______(flowersareseenalltheyearround).
October1stistheday________(newChinawasfounded).
4.why指原因,其先行词是原因,起原因状语作用。
Nobodyknowsthereasonwhyheisoftenlateforschool.
=Nobodyknowsthereasonforwhichheisoftenlateforschool.
注意:
关系副词when,where,why,的含义相当于“介词+which”结构,因此常常和“介词+which“结构交替使用。
IwillneverforgetthedayonwhichImetmyfavoritestar.【when】
NanjingistheplaceinwhichIwasborn.【where】
Isthisthereasonforwhichherefusedouroffer?
【why】
►注意:
当先行词为point,situation,case,stage时定语从句可用where引导
1.Themediacandrawattentiontosituationwherehelpisneeded.
2.Wehavereachedastagewherewehavealmostnorights.
3.Today,we’lldiscussanumberofcaseswherebeginnersofEnglishfailtousethelanguageproperly.
4.Wearejusttryingtoreachapointwherebothsideswillsitdowntogetherandtalk.
