状语从句

状语从句

由从句担任的状语,在句子中可修饰谓语(或其它动词)、形容词、副词或是整个句子,它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。

(一)时间状语从句

表示时间的状语从句可由when,as,while,whenever,after,before,till(until),since,once,assoonas(或themoment),bythetime,nosoonerthan,hardly(scarcely)when,everytime等引导。

e.g.WhenIcameintotheoffice,theteacherswerehavingameeting.

      Hestartedassoonashereceivedthenews.

      Onceyouseehim,youwillneverforgethim.

      NosoonerhadIgonetobedthanIwenttosleep.

(二)原因状语从句

      原因状语从句是表示原因或理由的,引导这类从句的最常用的连词是because,since,as,nowthat(既然)等,for表示因果关系时(它引导的不是从句)为并列连词,语气不如because强。

      e.g.Heisdisappointedbecausehedidn'tgettheposition.

             Asitisraining,Iwillnotgoout.

             Nowthatyoumentionit,Idoremember.

(三)地点状语从句

引导地点状语从句的连词是where和wherever等。

e.g.Sitwhereveryoulike.

      Makeamarkwhereyouhaveaquestion.

(四)目的状语从句

引导目的状语从句最常用的词(组)是so,sothat(从句谓语常有情态动词),inorderthat,incase(以防,以免)等。

e.g.Speakclearly,sothattheymayunderstandyou.

      ShehasboughtthebookinorderthatshecouldfollowtheTVlessons.

      Heleftearlyincaseheshouldmissthetrain.

(五)结果状语从句

      结果状语从句是表示事态结果的从句,通常主句是原因,从句是结果。

由sothat(从句谓语一般没有情态动词),sothat,suchthat等引导。

      e.g.Shewasill,sothatshedidn’tattendthemeeting.

             Hewassoexcitedthathecouldnotsayaword.

             Sheissuchagoodteacherthateveryoneadmiresher.

(六)条件状语从句

      条件状语从句分真实性(有可能实现的事情)与非真实性(条件与事实相反或者在说话者看来不大可能实现的事情)条件句。

引导条件状语从句的词(组)主要有if,unless,so(as)longas,onconditionthat,so(as)faras,ifonly(=if)。

注意:

条件从句中的if不能用whether替换。

       e.g.Ifheisnotintheoffice,hemustbeoutforlunch.

             Youmayborrowthebooksolongasyoukeepitclean.

             SofarasIknow(据我所知),hewillbeawayforthreemonths.

             Youcangoswimmingonconditionthat(=if)youdon’tgotoofarawayfromtheriverbank.

             Ifhehadcomeafewminutesearlier,hecouldhaveseenher.

(七)让步状语从句

      让步状语从句可由although,though,as,evenif(though),however,whatever,whetheror,nomatterwho(when,what,)等引导。

注意:

as引导的让步状语从句一般是倒装的。

      e.g.Thoughheisachild,heknowsalot.

             Childasheis,heknowsalot.

             Whatever(=Nomatterwhat)yousay,I’llneverchangemymind.

(八)方式状语从句

      方式状语从句常由as,asif(though),theway,ratherthan等引导。

      e.g.YoumustdotheexerciseasIshowyou.

             Heactedasifnothinghadhappened.

(九)比较状语从句

      比较状语从句常用than,so(as)as,themorethemore等引导。

      e.g.Ihavemadealotmoremistakesthanyouhave.

             Hesmokescigarettesasexpensiveashecanafford.

             Thebusierheis,thehappierhefeels.

(十)使用状语从句时要注意的几个问题

      1.在时间和条件(有时也在方式、让步等)从句中,主句是一般将来时,从句通常用一般现在时表示将来。

      e.g.We’llgooutingifitdoesn’traintomorrow.

             I’llwritetoyouassoonasIgettoShanghai.

      2.有些时间、地点、条件、方式或让步从句,如果从句的主语与主句主语一致(或虽不一致,是it),从句的谓语又包含动词be,就可省略从句中的主语+be部分。

      e.g.When(hewas)stillaboyoften,hehadtoworkdayandnight.

             If(youare)askedyoumaycomein.

             If(itis)necessaryI’llexplaintoyouagain.

      3.注意区分不同从句:

引导的是什么从句,不仅要根据连词,还要根据句子结构和句意来判别。

以where为例,能引导多种从句。

      e.g.Youaretofinditwhereyouleftit.(地点状语从句)

             Tellmetheaddresswherehelives.(定语从句,句中有先行词)

             Idon’tknowwherehecomesfrom.(宾语从句)

             Wherehehasgoneisnotknownyet.(主语从句)

             Thisplaceiswheretheyoncehid.(表语从句)
