中考英语语法之状语从句讲解及练习
中考专题二状语从句
主讲老师:
任帅
概念:
状语从句在句中作状语
分为:
时间、条件、让步、原因、目的、结果、比较、地点、方式。
一、时间状语从句
引导时间状语从句的连词有:
when,as,while,until,not…until,before,after,since,theminute,themoment,each(every,next,thefirst)time等。
时间状语从句中一般用一般现在时或一般过去时。
1.when,while,as都可解释为“当```的时候”但侧重点有所不同。
1)When
Eg:
WhenIarrivedhome,Ihadalittlerest.
注意:
when从句的主语与主句主语相同,谓语动词是be动词时,从句主语和be可以省略。
Eg:
When(shewas)walkingalongthestreet,shemetherclassteacher.
2)As
As除了表示“当```的时候”,还可表示为“一面```一面”,“随着”
Eg:
Hesangashedanced.(一面```一面)
Youwillgrowwiserasyougrowolder.(随着)
3)While表示“当```的时候”强调主句的动作和从句的动作同时发生,从句一般用进行时,从句动词必须是延续性动词。
Eg:
Whilewewereworking,theywerehavingarest.
While(theywere)havingadiscussion,theygotveryconfused.
注意:
while还有“然而”的意思。
eg:
Ipreferblacktea,whilehelikescoffee.
2.until,not…until“直到```才”,在肯定句中主句常用延续性动词;在否定句中主句常用短暂性动词。
肯定句:
Iwaiteduntilmidnight.
否定句:
Ididnotleaveuntilmidnight.
注意:
1)notuntil…在句首,主句用倒装
eg:
NotuntilyouhadexplainedhowdidImanagetodoit.
2)Itisnotuntil…that…引导的强调句
Itwasnotuntilitwasdarkthathecameback.
3.theminute,themoment,eachtime表示“一```就```”
eg:
Theworkerrecognizedthetypeofthemachinethemomenthesawit.
4.hardly/scarcely…when,nosooner…than,assoonas
表示为“一```就```”
eg:
Ihadhardly/scarcelygothomewhenitbegantorain.
Ihadnosoonergothomethanitbegantorain.
ItbegantorainassoonasIgothome.
注意:
hardly/scarcely…when,nosooner…than位于句首,主句用倒装
eg:
HadIhardly/scarcelygothomewhenitbegantorain.
NosoonerhadIgothomethanitbegantorain.
5.Bythetime+状从(过去时),主句(过去完成时)
Bythetime+状从(现在时),主句(将来完成时)
Bythetimeshecameback,alltheguesthadleft.
Bythetimetheclassisover,wewillhavefinishedlearningthewholepassage.

2、如果主句是祈使句,那么从句通常要用一般现在时。

三.让步状语从句
1.概念:
一般翻译为“尽管……即使……”就是我们日常生活中用的“退一步说……”的感觉。
2.引导让步状语从句的连词有:
though,although,evenif/though,however,nomatterhow,nomatterwhat,nomatterwho等。
(1)though,although表示“虽然,纵然”之意。
这两个连词意思大致相同,在一般情况下可以互换使用,都可与yet,still或nevertheless连用,但不能与but连用。
Although/Thoughhewaswornout,(still)hekeptonworking.
Although/Thoughheisveryold,(yet)heisquitestrong.
注意:
though引导的让步状语从句还可位于主句主句之后。
Shepassedtheexaminationthoughshehadnotstudiedveryhard.
(2)as表示“虽然……但是”,“纵使……”之意。
as引导的让步状语从句必须以部分倒装的形式出现,though间或也用于这样的结构中,但although不可以这样用。
Objectas/thoughyoumay,I’llgo.
(=Though/Althoughyoumayobject,I’llgo.)
Hardas/thoughheworks,hemakeslittleprogress.(=Thoughheworkshard,hemakeslittleprogress.)
Childas/thoughhewas,heknewwhatwastherightthingtodo.(=Thoughhewasachild,heknewwhatwastherightthingtodo.)
(3)evenif,eventhough表示“即使……”,“纵使……”之意。
意思基本相同,常可互换使用,但意义有细微差别。
evenif引导的让步从句含有强烈的假定性,而eventhough引导让步状语从句时,是以从句的内容为先决条件的。
We’llmakeatripevenif/thoughtheweatherisbad.
Evenifheispoor,sheloveshim.
(=Hemaybepoor,yetsheloveshim.)
Eventhoughheispoor,sheloveshim.
(=Heispoor,yetsheloveshim.)
(4)whether...or...表示“不论是否……”,“不管是……还是……”之意。
You'llhavetoattendtheceremonywhetheryou'refreeorbusy.
Whetheryoubelieveitornot,it'strue.
(5)“nomatter+疑问词”或“疑问词-ever”为“……都……;不管……都……”,
Nomatterwhathappened,hewouldnotmind.(=Whateverhappened,hewouldnotmind.)
Nomatterwhoyouare,youmustkeepthelaw.(=Whoeveryouare,youmustkeepthelaw.
注意:
“nomatter+疑问词”结构只能引导让步状语从句,而“疑问词-ever”还可以引导名词性从句。
Whatever(=Nomatterwhat)yousay,Iwon’tbelieveyou.
I'lleatwhatever(≠nomatterwhat)yougiveme.
