二、状语从句中的引导词1.while

while引导时间状语从句时，从句的谓语必须是延续性动词（如stay,wait,live等），而不能是非延续性动词。如：

Pleasedon’ttalksoloudwhileothersareworking.while引导让步状语从句时，相当于although/though/as，但while/although引导的让步状语从句不用倒装语序，though引导的让步状语从句可以倒装也可以不倒装，而as引导的让步状语从句则必须倒装。如：While/Although/Thoughthebrideishappy,shewillfeelhomesickatthebeginning.Happyasthebrideis,shewillfeelhomesickatthebeginning.2.until和tilluntil和till都表示“直到”，常可互换，但till一般不用于句首，也不用于强调句中。

until/till从句与肯定的主句连用时，主句的谓语必须是延续性动词，表示主句的动作一直持续到until/till所表示的时间为止。如：Youmaystayhereuntiltherainstops.Mr.Bushremainedtheretillhisbrotherarrived.until/till从句与否定的主句连用时，主句的谓语是非延续性动词，表示“直到……才”，即主句的动作到until/till所表示的时间才开始。如：

Davidwon’tgotobeduntil/tillhiswifereturns.Leodidn’tcomeuntilhehadgoneoverhislesson.

notuntil位于句首时，主句须用倒装语序。如：

NotuntilIbegantoworkdidIrealizehowmuchtimeIhadwasted.notuntil结构可用于强调句中。如：

Itwasnotuntilshecametoseeusthatweknewhermotherwasillinbed.3.whenwhen引导时间状语从句时，从句的动作既可与主句的动作同时发生，也可先后发生。如：

Whenwewereatschool,wewenttothelibraryeveryday.Whenthemealwasfinished,Rachelwashedup.when可以引导条件状语从句，意为“如果”。如：

Howcanweexplainittoyouwhenyouwon’tlisten?when可以作并列连词，意为“正在那时，突然”，此时所引导的从句只能放在主句之后。如：

Wewereswimminginthelakewhensuddenlythestormstarted.4.asas可以引导时间状语从句，其动作是延续性的，表示“当……时，随着”。

Theatmospheregetsthinnerandthinnerastheheightincreases.as可以引导原因状语从句，一般放在句首，表示十分明显的原因。如：

Asitisraining,weshallnotgocamping.as可以引导让步状语从句,通常用倒装结构。具体情况如下：形容词或副词+as+主语+系动词be或实义动词。如:MuchasIlikeit,Iwon’tbuy.

名词+as+主语+系动词（句首的名词前多不带冠词）。如：

Childasheis,heknowsalot.

实义动词+as+主语+助动词（如果没有助动词,则要加上do,does或did）。如：

Tryashewould,hecouldn’tlifttheheavybox.5.nosooner...than...,hardly/scarcely...when...nosooner...than...和hardly/scarcely...when...引导的从句表示“一……就……，刚……就……”的含义。主句中的动词一般用过去完成时,从句用一般过去时。nosooner,hardly位于句首时,主句的主谓语要部分倒装。如：

Thewordshadnosoonerbeenspokenthanherealizedthatheshouldhaveremainedsilent.Ihadhardlygothomewhenitbegantorain.Nosoonerhadwegottothestationthanthetrainleft.Hardlyhadwebegunwhenweweretoldtostop.6.由“疑问词-ever”构成的复合词与“nomatter+

疑问词”由“疑问词-ever”构成的复合词可以引导让步状语从句。此时以-ever结尾的复合词在口语中可由“nomatter+疑问词”代替。如：

I’vetoldyouthatI’mgoingtobuythatpen,howevermuchitcosts.=...,nomatterhowmuchitcosts.Don’ttrusthim,whateverhesays.=...,nomatterwhathesays.常见考点在含状语从句的复合句中，主、从句通常根据实际时间关系来确定动词的时态，但有一点需要注意：在时间状语从句、条件状语从句或由“疑问词-ever”、“nomatter+疑问词”等引导的让步状语从句中，可以用一般现在时表将来。下面就状语从句考点进行归纳总结。一、时间状语从句【考例】Itwasthemiddleofthenight_____myfatherwokemeupandtoldmetowatchthefootballgame.A.thatB.asC.whichD.when二、地点状语从句

where在地点状语从句中，除了指地点外，还可指处境等。由where引导的地点状语从句与定语从句的区别：where引导定语从句时，从句前应有一个表示（抽象）地点或处所的名词作先行词，而状语从句前没有先行词。【考例】Halfanhourlater,Lucystillcouldn’tgetataxi_____thebushaddroppedher.A.untilB.whenC.althoughD.where2.Manycountriesarenowsettingupnationalparks_____animalsandplantscanbeprotected.A.whenB.whichC.whoseD.where三、原因状语从句引导原因状语从句的常用连词有because,since,as,now(that)等。它们的用法区别是：because语气最强，述说直接原因，说明因果关系，常回答以why开头的问句；since,as和now(that)引导的从句用法相似，表示双方都知道的原因。【考例】—Coach,canIcontinuewiththetraining?—Sorry,youcan’t_____youhaven’trecoveredfromthekneeinjury.A.untilB.beforeC.asD.unless四、让步状语从句【考例】_____theforestparkisfaraway,alotoftouristsvisititeveryyear.A.AsB.WhenC.EventhoughD.Incase五、目的状语从句【考例】Cathyhadquitherjobwhenhersonwasborn_____shecouldstayhomeandraiseherfamily.A.nowthatB.asifC.onlyifD.sothat六、结果状语从句

so...that和such...that表示“如此……以致于”,so后面接形容词或副词，such后面接名词。但名词前有many,much,few,little这些词修饰时,要用so。“such+a(n)+adj.+单数名词+that”可转换成“so+adj.+a(n)+单数名词+that”。

【考例】Theweatherwas_____coldthatIdidn’tliketoleavemyroom.A.reallyB.suchC.tooD.so七、条件状语从句

【考例】Youwillnevergainsuccess_____youarefullydevotedtoyourwork.A.whenB.becauseC.afterD.unless八、方式状语从句引导方式状语从句的常用连词有as,asif/though。asif/though引导的状语从句的谓语动词常用虚拟语气，表示与事实相反的假设。如果从句所表达的内容被看作是事实或者有可能是事实时，就要用陈述语气。

【考例】Jackwasn’tsayinganything,buttheteachersmiledathim_____hehaddonesomethingveryclever.A.asifB.incaseC.whileD.though九、比较状语从句含as...as...的比较状语从句用在同级比较中,若表否定用notso/as...as...。其中第一个so/as是副词,修饰主句的形容词或副词的原形，后一个as是连词,引导比较状语从句。
