专题十三状语从句易错点集锦

一．时间状语从句的易错点

连接词用法例句

when,while,aswhen既可表示时间段，也可表示时间点，表示主句和从句的动作同时发生或从句的动作先于主句的动作发生Whenshecamein,Istoppedeating.WhenIlivedinthecountryside,Iusedtocarrysomewaterforhim.

while强调主从句的行为或状态同时发生或存在，从句用延续性动词Whilemywifewasreadingthenewspaper,IwaswatchingTV.

as通常和when通用，另外它还表示“随着······,一边······一边······”Youcanfeeltheairmovingasyourhandpushesthroughit.Ourheadmasterlaughedasshespoke.

before表示“在······之前，还未······就······,还没来得及···就···”Einsteinalmostknockedmedownbeforehesawme.MyfatherhadleftforCanadajustbeforetheletterarrived.Theyhadnotbeenmarriedforfourmonthsbeforetheyweredivorced.

Itwillbe/was+时间段＋before表示“多久之后才······”Itwillbefourdaysbeforetheycomeback.

sincesince从句中的谓语动词一般是非延续性动词，主句的谓语动词用完成时IhavebeeninBeijingsinceyouleft.

用在“Itis+时间段＋since...”中，表示“自从······以来已经多长时间了”；since从句中的动词如果是延续性的，则理解为“某一动作已经结束多久了”Itisthreeyearssincehebegantosmoke.Ithasbeen/isthreeyearssincewemetlasttime.

until/till用于肯定句，表示主句谓语动词的动作一直持续到某一时间为止Weshallwaituntil/tillhecomesback.Everythingwentwelluntil/till.thataccidenthappened.

用于否定句，构成not...until句型，意为“直到······才·····”Ididntgotobeduntil-Ifinishedmyhomework.Ididntleaveuntil/tillshecameback.

notuntil置于句首，主句用部分倒装语序NotuntilshestoppedcryingdidIleave.

用于强调句型：Itis/wasnotuntil...that...Itwasnotuntilthemeetingwasoverthathebegantoteachme

after...之后Afterwehadfinishedthework,wewenthome

once一旦...Onceyoustart,youwillnevergiveup.

whenever无论何时Youarealwayswelcomewheneveryoucome.

assoonas,immediately,instantly,directly,theminute/moment充当连词引导时间状语从句，表示主从句的动作同时发生，意为“一··就···...”AssoonasIreachCanada,Iwillringyouup.Theyphonedherimmediatelytheyreachedhome.HesaidhedturnonTVthemomenthegothome.

nosooner...than,hardly/scarcely...when意为“刚......就......＂，nosooner,hardly,scarcely后用过去完成时，than,whe
