时间状语从句可以放在主句之前，也可放在主句之后。我们常用when,while,before,after来引导时间状语从句。WhenIwasachild,mydreamwastobecomeanOlympicswimmer.Oneday,whileIwastraining,Ihurtmyshoulder.Ihadtogetmonthsoftreatment.Whenmyshoulderwasbetter,Ihadtoworkhardtogetbackintoshape.AfterIgotwell,Itrainedforfouryearsandfinallymademydreamcometrue!Mycoachwasproudofme.Hewassureaboutmysuccessbeforetheaccidenthappened.Andhenevergaveuponmeevenduringthemostdifficulttimes.Matchtheconjunctionswiththepropermeanings.a.duringacertaintime b.atacertaintimec.laterthanacertaintimed.earlierthanacertaintimeaabcdWhenweusebefore,after,whenorwhile_____(

②Whenthebellrang,hereachedforit.

when意思是“当……时”，表示主句发生的特定时间。既可以表示在某一时间点发生的事，又可以表示在某一时间段发生的事。注意：when引导的从句的谓语动词可以是延续性的，也可以是瞬时性的。1.when引导的时间状语从句在她很小的时候，她就会弹钢琴了。电话铃响，他伸手去接。Whileshewascookingdinner,herphonerang.Whilemysisterwassweepingthefloor,Iwaswashingthedishes.2.while引导的时间状语从句while意思是“当……时”，强调主句动作是和从句动作同时发生的。注意：while引导的从句的谓语动词必须是延续性的。while还可以表示“在……期间”，表示主句动作发生在从句动作进行的过程中。她在做晚饭的时候，电话响了。我姐姐扫地时，我在洗碗。在when和while引导的从句中，当主句和从句的主语一致，并且从句中有be动词时，从句可以省略主语和be动词，构成“when/while+动词-ing/介词短语”结构。①

introuble,shealwaysaskformyhelp.

②

While(Iam)travelling,Iliketobuysomesouvenirs.

她遇到困难时，总是向我求助。旅游时我喜欢买纪念品。before意为“在……之前”，表示主句动作发生在从句动作之前。①

Closethewindowsbeforeyouleavetheroom,please.

②

Beforewestartourlesson,let’sreadthewords.3.before引导的时间状语从句在你离开房间前，请关上窗。上课之前，我们先读单词。after意为“在……之后”，表示主句动作发生在从句动作之后。①

②

IhaveknownBillsincehewasborn.

since意为“自从……以来”。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。注意：since引导的从句的谓语动词可以是延续性动词，也可以是瞬时动词。1.since引导的时间状语从句他们从小学起就一直是好朋友。从比尔出生起，我就认识他。①Isleptuntil/tillmyfathercameback.

②UntilIcame,theywerereadingnewspapers.

2.till/until引导的时间状语从句•till和until意思是“到……为止”，一般情况下两者可以互换，但till不如until正式。•until可以放在句首或句中，而till一般不放在句首。注意：till/until用在肯定句中时，表示主句的动作或状态一直持续到从句动作发生或状态出现时为止，因此主句的谓语动词必须是可延续性的。我一直睡到爸爸回来。直到我到了，他们还在读报纸。①Wedidnotgetoffthebustill/untilitstopped.

②Wedidn'trealizetheimportanceofEnglishtill/until

weleftschool.

如果主句中的谓语动词是瞬时动词，该动词用否定形式，即“not...till/until”结构，意思是“直到……才（开始）”，表示主句的动作在从句的动作发生之后才开始。直到车停了，我们才下了公交车。我们直到离开学校才意识到英语的重要性。PracticeSandyandSimonaretalkingabouttheirdreams.Completetheirconversationusingsinceortill/until.P41B1sinceuntil/tilluntil/tillsincesinceuntil/tillHaveyousetagoalrecently?Talkaboutitwithyourpartner,usingsinceandtill/until.P41B2SinceIenteredGrade9,Ihavemadeagoaltostudyhard.Iwillstudyhardtill/untilIgetgoodgrades.1.Whatdoesthewriterdowhenfacingdifficulties?Why?2.Whatbeliefdoesthewriterholdtogetsuccess?WheneverIfaceachallenge,Ithinkaboutmyrolemodel.Hisexperiencegivesmehopeassoonasitcomestomind.IknowifInevergiveup,Iwillsucceed.Readthetextandanswerthequestions.12WheneverIfaceachallenge,Ithinkaboutmyrolemodel.Hisexperiencegivesmehopeassoonasitcomestomind.IknowifInevergiveup,Iwillsucceed.Payattentiontotheadverbialclausesoftime.我们也常用assoonas和whenever来引导时间状语从句。Matchtheconjunctionswiththepropermeanings.a.
