定语从句中需注意事项有些情况下只用关系词that,而不宜用which1.从句所修饰的词又被形容词最高级或序数词修饰时

Thisisthemostinterestingstory(that)Ihaveeverheard.Thefirstmeeting(that)wewilltakepartinwillbeheldintheafternoon.

2.先行词是something,nothing,anything等不定代词时

Hereissomething(that)Iwilltellyou.2021/5/973.先行词既有人也有物时,只能用thatIcanrememberwellthepersonsandsomepictures(that)Isee.

4.先行词是oneof,theone,或用little,much,few,no,all,some,any,theonly,thevery,thesame,thelast作修饰时

Isittheonethatyouwant?Ihaven’tgotmuchthatIcanofferyou.5.当主句已有疑问词who或which时，用thatWhoisthewomanthatwaspraisedatthemeeting?2021/5/98注:who、that在指人可以通用，但下列宜用

who,不用that

1).先行词是anyone,someone,those时，关系词使用whoThosewhowanttogototheGreatWallsignuphere.Isthereanyonewhowantstogothere?2).在therebe句型中，先行词指人,关系词用whoThereisanoldmanwhowantstoseeyou.Therearemanyyoungmenwhoareagainsthim.2021/5/99————关系副词

关系副词是用来引导定语从句的，它和关系代词一样,在从句中代替先行词,在句中作状语。

where:在从句中作地点状语,指代地点.

when:

在从句中作时间状语,指代时间。

why:在从句中作原因状语，指代原因.Istillrememberthefirstday(whenImetyouingrade7.)Stonehengewasatemple(whereancientleaderstriedtocommunicatewithgods.)Wedon’tknowthereason(whyhewaslateforschool.)2021/5/910

定语从句谓语动词和先行词一致。注:定语从句的时态不受主句的限制。
