初二（2）班

狀語從句？.狀語從句指句子用作狀語時，起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或整個句子。根據(jù)其作用可分為時間、地點、原因、條件、目的、結(jié)果、讓步、方式和比較等從句。狀語從句一般由連詞(從屬連詞)引導，也可以由詞組引起。從句位于句首或句中時通常用逗號與主句隔開，位于句尾時可以不用逗號隔開。

1、Callme2、Hewillprobablygotouniversity3、Althoughtheweatherishot,manychildrenaremakingsandcastlesatthebeach.4、someanimalsstartsleeping.5、Youforgottoturnoffthelight6、Ican’twalkanymorebecausemyfeethurt.7、Ihavelivedhere8、Manypeoplechoosetotravelbyundergroundbecauseitisfastandconvenient.找出時間狀語從句assoonasyougettoLondon.afterheleavesschool.Whenwintercomes,beforeyouwenttobedlastnight.sinceIwasborn.時間狀語從句常由下列連詞引導：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.

①表示點時間時，從句中用短暫性動詞；表示一段時間時，用持續(xù)性動詞eg.

WhenIgothome,myfamilywerealreadyhavingdinner.

Whentheywerestilltalkingandlaughing,theteachercamein.

Whenyouthinkyouknownothing,youbegintoknowsomething.

②when可以引導賓語從句，表示什么時候。

IsaidwhenIfinishedmyhomework,Icouldgohome.

（when表示點時間）（when表示一段時間）(when表示一段時間）（when引導賓語從句）（when引導時間從句）時間狀語從句while

①while通常表示一段時間，從句中宜用持續(xù)性動詞作謂語。

HewaswatchingTv

whileshewasreadingthenewspaper.

②while有時可以作并列連詞，表示對比，可譯成……而……。

IamfondofEnglishwhilehelikesmaths.

Wesleptwhilethecaptainkeptwatch.③while有時可引導讓步狀語從句，意思是雖然。

Whiletheylovetechildren,theyarestrictwiththem.

ATTENTION:雖然during與while意思很相近，但是during是介詞，不能引導從句。時間狀語從句

as

①as表示點時間時，從句中用短暫性動詞；表示段時間時，用持續(xù)性動詞。as和when兩者經(jīng)?？梢酝ㄓ?。

eg.Thethiefwascaughtas/whenhewasstealinginthesupermarket.IsawJimas/whenheleftthemeetingroom.②as表示一邊……一邊……，強調(diào)從句和主句中兩個動作交替進行或同步進行。

eg.Theytalkedastheywalked.Helookedbehindfromtimetotimeashewent.③as表示隨著

eg.Astimegoeson,it'sgettingwarmerandwarmer.as引導原因狀語從句

Asyouareinpoorhealth,youshouldnotstayuplate.時間狀語從句when,while,as的用法區(qū)別

①只有當從句表示的是段時間，即其謂語動詞有持續(xù)性特征時，這三者可以通用互換。

eg.Igotthenewsontheradiowhen/while/asIwashavingbreakfast.②在下列情況下，三者彼此之間不能替換使用：a．a(chǎn)s更強調(diào)同一時間或緊接的一前一后或伴隨著的變化。

eg.Welistenedtothesingersingasheplayedtheguitar.Ithoughtofitjustasyouopenedyourmouth.

Ashegrewolder,hebecamelessandlessactive.

aswhilewhen

從句動詞意義as延續(xù)性動詞或短暫性動詞強調(diào)動作同時進行，一邊……一邊when延續(xù)性動詞，或短暫性動詞同時發(fā)生，或從句的動作發(fā)生在主句動作前后。While延續(xù)性動詞,多用過去進行時同時發(fā)生，往往側(cè)重主句和從句動作的對比用when,while,as填空1.Hestartedwritingmusic_______hewasfouryearsold.2.Hesmiled_______hestoodup.

3.Hevisitedalotofplaces_____________hewastraveling.

4.Theaccidenthappened_______Iwasonmywaytowork.5.Iwasverynaughty_______Iwasyoung.

CCACbefore

和after

引導的時間從句：before表示主句的動作發(fā)生在從句動作之前，after表示主句的動作發(fā)生在從句動作之后。①Beforeheplayedchesswithhischild,hehadfinishedhiswork.

Afterhehadfinishedhiswork,heplayedchesswithhischild.

IknewsomeEnglishafterIstartedschool.

Ididn'tknowanyEnglishbeforeIstartedschool.

Ididn'tknowanyEnglishuntilIstartedschool.

時間狀語從句till,until1．Until/till用于肯定句時，表示直到…為止，主句必須為持續(xù)性動詞。

eg.Weshallwaituntil/tillhecomesback.2．not…until/till表示直到…才，主句通常要用短暫動詞，這時until和till可用before代替。

eg.Ididn'tleaveuntil/till/beforeshecameback.Peopledonotknowthevalueoftheirhealthtill/until/beforetheyloseitWewaitedtill(until)hecamebackShedidn’tstopworkinguntileleveno’clock.如主句動詞是延續(xù)性動作，常用肯定式，表示“直到…為止”;如主句動詞是瞬間動詞，常用否定式，表示“直到…才”

［誤］Ifinishedmyhomeworkuntiltwelveo'clocklastnight.正誤辨析［正］Ididn'tfinishedmyhomeworkuntil/beforetwelveo'clocklastnight.

［正］Ididmyhomeworkuntiltwelveo'clocklastnight.

［析］until用在句中時其含義是某一動作一直持續(xù)到某時結(jié)束，那么句中的動詞則一定要用持續(xù)性動詞，如果要用瞬間，或截止性動詞時一定要用否定句式。因截止性動作的否定式應(yīng)看作是持續(xù)性的動作。如離開leave是瞬間動作，因一出門即為離開了，而不離開則是長時間的。

didn′tbefore小結(jié)：till,until和not…until：1.until/till從句用于肯定句時，主句的動詞是延續(xù)性動作，意為“某動作一直延續(xù)到某時間點才停止”。如：

Wewaiteduntil/tillhecame.2．用于否定句時，主句謂語動詞是非延續(xù)性動詞，意為“某動作直到某時間才開始”。如：

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

UntilyoutoldmeIhadnoideaofit.4．not…until句型中的強調(diào)和倒裝說法：

ItwasnotuntilyoutoldmethatIhadanyideaofit.

NotuntilyoutoldmedidIhaveanyideaofit.時間狀語從句Since1)since表示自……以來。表示動作從過去某一點時間一直延續(xù)到說話時間為止。主句中通常為延續(xù)性動詞的現(xiàn)在完成時，since從句中一般用短暫性動詞的一般過去時。

since從那以后一直(更加強調(diào)since的用法)Hisfirstbookwasagreatsuccessandhehasbeenfamousasawritereversince.時間狀語從句assoonasassoonas...可譯為一……就……，用來表示主從句的動作是緊接著發(fā)生的。eg.Hewillcomeandseeyouassoonashecan.

comeswilltalkwillcomecomeswillgo時間狀語從句Attention:在時間狀語從句中，沒有發(fā)生的動作遵循主將從現(xiàn)的原則。即從句為一般現(xiàn)在時，主句可為一般將來時，祈使句或者用情態(tài)動詞。eg.

I’lltelephoneyouassoonasIgetthere.

Don’tgetoffthebusuntilithasstopped.

1.［F］Whiletheclockstruckten,allthelightswentout.

［T］Whentheclockstruckten,allthelightswentout.［析］while是強調(diào)兩個動作在同時進行中，如：WhileIamdoingmyhomework,myfatherisreadinganewspaper.而這里的when是"正當某某時刻"，"就在這一時間點上"，其重點強調(diào)在某一特定時刻某動作的發(fā)生。

正誤辨析

2.［誤］WhileIwaswalkingalongthestreetyesterday,Imetanoldfriend.

［正］WhenIwaswalkingalongthestreetyesterday,Imetanoldfriend.

3.［誤］WhileIheardthebadnewsIfeltsad.

［正］WhenIheardthebadnews,Ifeltsad.

正誤辨析［析］這里用when表達在一個動作的進行中，另一個動作突然發(fā)生了。正在進行的動作用一進行時態(tài)，而突然發(fā)生的動作用一般時態(tài)。

［析］while不能表達瞬時某一時間點。3.［誤］Shesangwhenshewalkedalongthedarkstreet.［正］Shesangasshewalkedalongthedarkstreet.

正誤辨析［析］as用于句中時，其要點是強調(diào)兩個動作的同時進行。這里用when雖然不能講是語法上的錯誤，但則看不出來小女孩因獨自走黑暗的街道因害怕而唱歌的心情。

4.［誤］IhavestudiedEnglishwhenIwastwelve.［正］IhavestudiedEnglishsinceIwastwelve.

5.［誤］BeforeIdonotgiveyoutheanswer,I'llaskyousomequestions.

［正］BeforeIgiveyoutheanswer,I'llaskyousomequestions.

正誤辨析［析］since引出的時間狀語從句是表達了一個時間點，而這個時間點是主句動作的啟始點，所以主句一般要用完成時態(tài)。

［析］這種錯誤是由于受中文的影響。在中文中可以講"我沒給你答案前"。而英文用了before就不要再用否定句了。
