Unit12Lifeisfulloftheunexpected.SectionAGrammarFocus–4c1思考與討論：

1.在以下的時間狀語從句中，主句和從句的動作是先后發(fā)生還是同時發(fā)生？

2.主從句都用一般過去時態(tài)的時間狀語從句的引導(dǎo)詞有什么？Whenhecamein,thestudentsstoodup.Whenthebabysawhermother,shestoppedcrying.Hewasabouttowatchamoviewhenhisparentsknockedatthedoor.Theywereabouttogetonthebuswhentheyheardsomeoneshout.AsIwasstandinginfrontoftheteacher’soffice,Isawaboyfightwithanotherboy.Ashewasdoinghousework,abirdflewintothekitchen.2

1）在以上的時間狀語從句中，主句和從句的動作是同時發(fā)生，或者是在進(jìn)行一個動作時，另外一個動作突然發(fā)生。

2）主從句都用一般過去時態(tài)的時間狀語從句引導(dǎo)詞有（when,as）等Whenhecamein,thestudentsstoodup.Whenthebabysawhermother,shestoppedcrying.Hewasabouttowatchamoviewhenhisparentsknockedatthedoor.Theywereabouttogetonthebuswhentheyheardsomeoneshout.AsIwasstandinginfrontoftheteacher’soffice,Isawaboyfightwithanotherboy.Ashewasdoinghousework,abirdflewintothekitchen.3GrammarFocusWhenIgotoschool,IrealizedthatIhadleftmybackpackathome.BythetimeIgotbacktoschool,thebellhadrung.BeforeIgottothebusstop,thebushadalreadyleft.IwasabouttogouptomyofficewhenIdecidedtogetacoffeefirst.AsIwaswaitinginlinewiththeotherofficeworkers,Iheardaloudsound.4WhenIgotoschool,IrealizedthatIhadleftmybackpackathome.BythetimeIgotbacktoschool,thebellhadrung.BeforeIgottothebusstop,thebushadalreadyleft.IwasabouttogouptomyofficewhenIdecidedtogetacoffeefirst.AsIwaswaitinginlinewiththeotherofficeworkers,Iheardaloudsound.討論：為什么主句分別使用過去完成時態(tài)和一般過去時態(tài)在使用不同時態(tài)時從句和主句的動作的先后順序。5過去完成時(1)構(gòu)成：由“助動詞had(用于各種人稱和數(shù))+過去分詞”構(gòu)成否定式：hadnot+過去分詞

縮寫形式：hadn’t(2)用法：過去完成時表示在過去某一時間或動作之前已經(jīng)發(fā)生或完成了的動作。6(3)它所表示動作發(fā)生的時間是“過去的過去”。①表示過去某一時間可用by,before

等構(gòu)成的短語來表示。②也可以用when,before

等引導(dǎo)的時間狀語從句來表示。③還可以通過狀語從句或通過上下文暗示。7主語＋hadnot／hadn’t+p.p.+其它.Had+主語＋p.p.+其它?主語＋had+p.p.+其它.強(qiáng)調(diào)過去某一個動作發(fā)生在另一個動作前常常用過去完成時態(tài)。過去完成時的結(jié)構(gòu)過去完成時的用法過去完成時的否定形式過去完成時的疑問形式8過去完成時的判斷依據(jù):

由“過去的過去”來判定。

過去完成時表示“過去的過去”，先發(fā)生的動作用過去完成時，后發(fā)生的動作用一般過去時。

例：WhenIgottothestation,thetrainhadalreadyleft.

當(dāng)我到車站時，火車已經(jīng)離開了。Afterhehadfinishedhishomework,hewenttobed.完成作業(yè)后他就去睡覺了。

first

first9構(gòu)成：助動詞had+動詞的過去分詞用法：1.過去完成時動詞表示過去某一時間或某一動作之前完成的動作或狀態(tài)。強(qiáng)調(diào)過去某一動作發(fā)生在另一動作之前時。1.他說他以前見過你。Hesaidthathe______________(see)youbefore.hadseen2.到六點(diǎn)鐘為止他們已經(jīng)工作八小時了。Bysixo’clockthey______________(work)foreighthours.hadworked102.過去完成時詞可以表示過去某一時刻之前發(fā)生的動作或呈現(xiàn)的狀態(tài)，這一動作一直持續(xù)或?qū)⒗^續(xù)下去。Bysixo’clockthey____________(work)foreighthours.WhenIcametoGZ,he_____________(be)thereforalongtime.用法：1.到了六點(diǎn)鐘為止，他們已經(jīng)工作了八小時了。2.我到廣州時，他在那里很長時間了。hadworkedhadbeen3.到上個月中旬我們在北京住了有五年時間了。Bythemiddleoflastmonthwe______________(live)inBeijingforfiveyears.hadlived111.到昨晚上，他已寫完那封信。Byyesterdayeveninghe___________(write)thatletter.2.他說他以前見過你。Hesaidthathe____________(see)youbefore.3.當(dāng)我進(jìn)來時，他已做完了作業(yè)。WhenIcameinhe________________(finish)hishomework.過去完成時與bythen(截止到那時);by9o’clock(直到九點(diǎn)鐘)bytheendof…(在…結(jié)束/末之前);bythetime…(在…時之前);uptillthen(直到那時);upuntillastnight(直到昨晚）等連用，表示過去的過去。hadwrittenhadseenhadfinished123.過去完成時和already,just,ever,yet等連用表示過去的過去。用法：例如：1.他告訴我說他們隊已經(jīng)贏了。Hetoldmethathisteam_________already___________(win).hadwon2.她說她仍沒去過長城。Shesaidthatshe_______________(notgoto)theGreatWallyet.hadn’tbeento13用法：過去完成時與when,before,assoonas,

till/until

等引導(dǎo)時間狀語的從句連用，強(qiáng)調(diào)動作發(fā)生的時間前后。例如：1.她到家之前她的孩子已經(jīng)睡著了。Whenshegothomeherchildren____________(sleep).hadslept2.在他們到達(dá)之前電影已經(jīng)開始了。Beforetheyarrivedherethefilm_________already___________(start).hadstartedLastnight,assoonasI_______________

(finish)myworkIwenttosleep.3.我完成作業(yè)了就去睡覺了。hadfinished141.一般過去時表示在過去某時發(fā)生的動作或存在的狀態(tài)。例：WestartedtolearnEnglish5yearsago.我們五年前開始學(xué)英語。對比一般過去時、現(xiàn)在完成時與過去完成時5yearsago

now152.現(xiàn)在完成時表示的動作發(fā)生在過去，但側(cè)重對現(xiàn)在產(chǎn)生的結(jié)果或造成的影響，與現(xiàn)在有關(guān)。其結(jié)構(gòu)為：“助動詞have（has）+過去分詞”。例：WehavelearnedEnglishfor5years.我們已經(jīng)學(xué)了五年的英語了。5yearsago

havelearnednow163.

過去完成時表示在過去某個時間或動作之前已經(jīng)發(fā)生或完成了的動作或存在的狀態(tài)，即“過去的過去（past-in-the-past）”。例：WehadlearnedEnglish4yearbylastyear.

到去年為止，我們已經(jīng)學(xué)英語四年了。
