初二（2）班

状语从句？.状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

1、Callme2、Hewillprobablygotouniversity3、Althoughtheweatherishot,manychildrenaremakingsandcastlesatthebeach.4、someanimalsstartsleeping.5、Youforgottoturnoffthelight6、Ican’twalkanymorebecausemyfeethurt.7、Ihavelivedhere8、Manypeoplechoosetotravelbyundergroundbecauseitisfastandconvenient.找出时间状语从句assoonasyougettoLondon.afterheleavesschool.Whenwintercomes,beforeyouwenttobedlastnight.sinceIwasborn.时间状语从句常由下列连词引导：when,while,as,before,after,till,until,since,assoonas,…翻一翻Tomhome,hiswifeWhenarrivedwascooking.thestudent,theteacherWhilewaswritingwasreading.theman,thegirl.Whilewasdancingwassinginghethedoor,thegirlthefloor.Whenclosedwasmoppingwhile&when&as()1.______theteachercamein,thestudentsweretalkingandlaughing.A.whileB.sinceC.whenD.thetime()2.Sandywasoperatingonherpatient______Sammywasputtingoutfires.A.whileB.byC.whenD.before()3.Idon’tlikeMike.Heislazy.Hewasalwaysplayingcomputergames______hermotherwasworkinghardattheirhousework.A.asB.whileC.untilD.when()4.Thelittlechildrensanghappily______theywalkedalong.

A.when

B.whileC.untilD.asCABD时间状语从句when,while,as表示主句谓语作和从句的谓语动作同时发生或几乎同时发生。when

①表示点时间时，从句中用短暂性动词；表示一段时间时，用持续性动词eg.

WhenIgothome,myfamilywerealreadyhavingdinner.

Whentheywerestilltalkingandlaughing,theteachercamein.

Whenyouthinkyouknownothing,youbegintoknowsomething.

②when可以引导宾语从句，表示什么时候。

IaskedhimwhenIcouldgohome.

IsaidwhenIfinishedmyhomework,Icouldgohome.

（when表示点时间）（when表示一段时间）(when表示一段时间）（when引导宾语从句）（when引导时间从句）时间状语从句while

①while通常表示一段时间，从句中宜用持续性动词作谓语。

HewaswatchingTv

whileshewasreadingthenewspaper.

②while有时可以作并列连词，表示对比，可译成……而……。

IamfondofEnglishwhilehelikesmaths.

Wesleptwhilethecaptainkeptwatch.③while有时可引导让步状语从句，意思是虽然。

Whiletheylovetechildren,theyarestrictwiththem.

ATTENTION:虽然during与while意思很相近，但是during是介词，不能引导从句。时间状语从句

as

①as表示点时间时，从句中用短暂性动词；表示段时间时，用持续性动词。as和when两者经常可以通用。

eg.Thethiefwascaughtas/whenhewasstealinginthesupermarket.IsawJimas/whenheleftthemeetingroom.②as表示一边……一边……，强调从句和主句中两个动作交替进行或同步进行。

eg.Theytalkedastheywalked.Helookedbehindfromtimetotimeashewent.③as表示随着

eg.Astimegoeson,it'sgettingwarmerandwarmer.as引导原因状语从句

Asyouareinpoorhealth,youshouldnotstayuplate.时间状语从句when,while,as的用法区别

①只有当从句表示的是段时间，即其谓语动词有持续性特征时，这三者可以通用互换。

eg.Igotthenewsontheradiowhen/while/asIwashavingbreakfast.②在下列情况下，三者彼此之间不能替换使用：a．as更强调同一时间或紧接的一前一后或伴随着的变化。

eg.Welistenedtothesingersingasheplayedtheguitar.Ithoughtofitjustasyouopenedyourmouth.

Ashegrewolder,hebecamelessandlessactive.

aswhilewhen

从句动词意义as延续性动词或短暂性动词强调动作同时进行，一边……一边when延续性动词，或短暂性动词同时发生，或从句的动作发生在主句动作前后。While延续性动词,多用过去进行时同时发生，往往侧重主句和从句动作的对比用when,while,as填空1.Hestartedwritingmusic_______hewasfouryearsold.2.Hesmiled_______hestoodup.

3.Hevisitedalotofplaces_____________hewastraveling.

4.Theaccidenthappened_______Iwasonmywaytowork.5.Iwasverynaughty_______Iwasyoung.

CCACbefore

和after

引导的时间从句：before表示主句的动作发生在从句动作之前，after表示主句的动作发生在从句动作之后。①Beforeheplayedchesswithhischild,hehadfinishedhiswork.

Afterhehadfinishedhiswork,heplayedchesswithhischild.

IknewsomeEnglishafterIstartedschool.

Ididn'tknowanyEnglishbeforeIstartedschool.

Ididn'tknowanyEnglishuntilIstartedschool.

时间状语从句till,until1．Until/till用于肯定句时，表示直到…为止，主句必须为持续性动词。

eg.Weshallwaituntil/tillhecomesback.2．not…until/till表示直到…才，主句通常要用短暂动词，这时until和till可用before代替。

eg.Ididn'tleaveuntil/till/beforeshecameback.Peopledonotknowthevalueoftheirhealthtill/until/beforetheyloseitWewaitedtill(until)hecamebackShedidn’tstopworkinguntileleveno’clock.如主句动词是延续性动作，常用肯定式，表示“直到…为止”;如主句动词是瞬间动词，常用否定式，表示“直到…才”

［误］Ifinishedmyhomeworkuntiltwelveo'clocklastnight.正误辨析［正］Ididn'tfinishedmyhomeworkuntil/beforetwelveo'clocklastnight.

［正］Ididmyhomeworkuntiltwelveo'clocklastnight.

［析］until用在句中时其含义是某一动作一直持续到某时结束，那么句中的动词则一定要用持续性动词，如果要用瞬间，或截止性动词时一定要用否定句式。因截止性动作的否定式应看作是持续性的动作。如离开leave是瞬间动作，因一出门即为离开了，而不离开则是长时间的。

didn´tbefore小结：till,until和not…until：1.until/till从句用于肯定句时，主句的动词是延续性动作，意为“某动作一直延续到某时间点才停止”。如：

Wewaiteduntil/tillhecame.2．用于否定句时，主句谓语动词是非延续性动词，意为“某动作直到某时间才开始”。如：

Hewon’tgotobeduntilherfatherreturns.3．till不可以置于句首，而until可以。如：

UntilyoutoldmeIhadnoideaofit.4．not…until句型中的强调和倒装说法：

ItwasnotuntilyoutoldmethatIhadanyideaofit.

NotuntilyoutoldmedidIhaveanyideaofit.时间状语从句Since1)since表示自……以来。表示动作从过去某一点时间一直延续到说话时间为止。主句中通常为延续性动词的现在完成时，since从句中一般用短暂性动词的一般过去时。

since从那以后一直(更加强调since的用法)Hisfirstbookwasagreatsuccessandhehasbeenfamousasawritereversince.时间状语从句assoonasassoonas...可译为一……就……，用来表示主从句的动作是紧接着发生的。eg.Hewillcomeandseeyouassoonashecan.

他一有空就来看你。

Herushedhomeassoonashegotthegoodnews.

他一得到这个好消息就奔回家。用动词的正确形式填空1.I___________(write)backtoyouassoonasI______(get)yourletter.2.WhenI________(get)totheairport,theguests____________(justleave).3.Whilemywife___________(read)thenewspaper,I(watch)TV.4.Whenwe__________(dance),astranger______(come)in.5.AssoonasI_______(get)homeyesterday,it_______(begin)torain.6._______(have)agoodlookatthatmanwhenyou_______(pass)him.7.I

I’lltelephoneyouassoonasIgetthere.

Don’tgetoffthebusuntilithasstopped.

Whenyougettothesecondcrossingandturnright,youcanseethehotelinfrontofyou!

1.［F］Whiletheclockstruckten,allthelightswentout.

［T］Whentheclockstruckten,allthelightswentout.［析］while是强调两个动作在同时进行中，如：WhileIamdoingmyhomework,myfatherisreadinganewspaper.而这里的when是"正当某某时刻"，"就在这一时间点上"，其重点强调在某一特定时刻某动作的发生。

正误辨析

2.［误］WhileIwaswalkingalongthestreetyesterday,Imetanoldfriend.

［正］WhenIwaswalkingalongthestreetyesterday,Imetanoldfriend.

3.［误］WhileIheardthebadnewsIfeltsad.

［正］WhenIheardthebadnews,Ifeltsad.

正误辨析［析］这里用when表达在一个动作的进行中，另一个动作突然发生了。正在进行的动作用一进行时态，而突然发生的动作用一般时态。

［析］while不能表达瞬时某一时间点。3.［误］Shesangwhenshewalkedalongthedarkstreet.［正］Shesangasshewalkedalongthedarkstreet.

正误辨析［析］as用于句中时，其要点是强调两个动作的同时进行。这里用when虽然不能讲是语法上的错误，但则看不出来小女孩因独自走黑暗的街道因害怕而唱歌的心情。

4.［误］IhavestudiedEnglishwhenIwastwelve.［正］IhavestudiedEnglishsinceIwastwelve.

5.［误］BeforeIdonotgiveyoutheanswer,I'llaskyousomequestions.

［正］BeforeIgiveyoutheanswer,I'llaskyousomequestions.

正误辨析［析］since引出的时间状语从句是表达了一个时间点，而这个时间点是主句动作的启始点，所以主句一般要用完成时态。

［析］这种错误是由于受中文的影响。在中文中可以讲"我没给你答案前"。而英文用了before就不要再用否定句了。
