Fillintheblankswiththecorrectwords.Revision时间状语从句是指在复合句中充当时间状语的句子。如：Whentheweatherisgood,mygrandpalikesgoingfishing.当天气好的时候，我爷爷喜欢去钓鱼。Thesuncameoutafterthestormstopped.暴风雨停止后，太阳出来了。注意：我们可以用before,after,when和while引导时间状语从句，这些词既可放在句首，也可放在句中。GrammarA(Usingbefore,after,when&while)Beforehewasborn,manypeoplebelievedthathewouldbeabasketballstar.2.08m&1.88mBeforemeansearlierthanacertaintime.Tip1:beforebefore的意思是“在……之前”，表示主句动作发生在从句动作之前。如：Closethewindowsbeforeyouleavetheroom,please.在你离开房间前，请关上窗。Afterhetooksomebasketballtraining,heshowedhistalent(才能)inthegame.Tip2:Aftermeanslaterthanacertaintime.afterafter意思是“在……之后”，表示主句的动作发生在从句的动作之后。如：IwenttoschoolafterIfinishedmybreakfast.我吃完早饭去上学。3.Youshouldturnoffthelights_________youleavetheroom.=Youshouldturnoffthelights________________theroom.4.Tomwenttoschool________hefinishedhisbreakfast.=Tomwenttoschool______________hisbreakfast.beforebeforeleavingafterfinishingafter1.Youcan’twatchTV____youfinishyourhomework.(2013泰州)A.after B.ifC.whenD.before2.Youshouldhandinyourtestpaper__youcheckit.(2014常州)A.whileB.whenC.beforeD.afterFinishPartA:Combinethesentencesusingbefore,after,whenorwhile.(P54)1.Igojoggingeverymorning.ThenIhavebreakfast.2.Ipractisedplayingbasketballforhours.Ifelttiredout.

when

meansatacertaintime.（在某个特定的时间点）

Tip3:When/Whilemeanduringacertaintime.(在特定的时间期间)Tip4:when意思是“当……时”，表示主句动作发生在特定的时间。如：Whilemysisterwassweepingthefloor,Iwaswashingthedishes.我姐姐扫地时，我在洗碗。while意思是“当……时”，强调主句动作和从句动作是同时发生的。如：Thedaysgetlongerwhenspringcomes.春天到来时，白天变长了。注意：while引导的从句的谓语动词必须是延续性的。二.whenandwhile1.Howtousewhenandwhilea.whenmeansatorduringacertaintime既指时间点，也可指一段时间；意为“当……时”，表示主句动作发生在特定的时间。如：Thedaysgetlongerwhenspringcomes.春天到来时，白天变长了。whilemeansduringacertaintime只指一段时间，因此when引导的时间状语从句中的动词可以是短暂性动词（瞬间动词），也可以是延续性动词，而while从句中的动词必须是延续性动词。b.when说明从句的动作和主句的动作可以是同时，也可以是先后发生；WhenIwaswatchingTV,someoneopenedthedoor.1）while意思是“当……时”，强调主句动作和从句动作是同时发生的。如:Whiletheboyswereplayingfootball,itrained.当男孩子们踢足球时，下雨了。Whilemysisterwassweepingthefloor,Iwaswashingthedishes.我姐姐扫地时，我在洗碗。2）while表示“在……期间”时，表示主句动作发生在从句动作进行的过程中。如:

while则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。如：c.由when引导的时间状语从句,主句用过去进行时，从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导如：

1).Whentheteachercamein,weweretalking.当此句改变主从句的位置时，则为：

2)Whileweweretalking,theteachercamein.3).Theyweresingingwhileweweredancing.d.when和while还可作并列连词。when表示“在那时”；while表示“而，却”，表对照关系。如：1).Thechildrenwererunningtomovethebagofrice

whentheyheardthesoundofamotorbike.孩子们正要跑过去搬开那袋米，这时他们听到了摩托车的声音。2).Heisstrongwhilehisbrotherisweak.他长得很结实，而他弟弟却很瘦弱。

since,till和until常用来引导时间状语从句。如：since,till和until引导的时间状语从句MrBrownhasbeeninBeijingsinceyouleft.自从你离开，布朗先生就一直待在北京。Iworkedtill/untilhecameback.我一直工作到他回来为止。YaoMinghasbeeninthenationalbasketballteamsincehewas18yearsold,Sincehejoinedit,hehaswonmanycompetitions.since在一般情况下，从句的谓语动词用一般过去时，而主句的谓语动词用现在完成时。GrammarB(Usingsince,till,&until)Tip5:Sincemeansfromacertaintime.Hedidnotgetthechancetobeworld-famousuntilhejoinedtheNBA.Hepracticedplayingbasketballveryharduntil/till2011.Thenheendedhisbasketballcareer(事业).

or

thesentence,buttillisusuallyused

thesentence.atthebeginninginthemiddleofinthemiddleoftill和until意思是“到……为止”，一般情况下两者可以互换。until可以放在句首或句中，而till不可以用在句首。注意：如果主句中的谓语动词是瞬时动词时，必须用否定形式，即“not…until”结构，意思是“直到……才（开始）”。如：Walktill/untilyouseeawhitehouse.一直走到你看到一座白房子为止。IdidnotgotobeduntilIfinishedmyhomework.直到做完作业我才上床睡觉。注：当我们使用not…until结构时，不能使用till代替until句首通常只用until,不用till。例如：

1).Untilthen,Iknewnothingatallaboutit.

在那之前，我对此事一无所知。

2).UntilyoutoldmeIhadnoideaofit.

在你告诉我之前，我对此一无所知。某些固定词组或谚语中通常只用till。例如：

1).frommorningtillnight

从早到晚。

2).uptillnow
