Unit12Lifeisfulloftheunexpected.SectionAGrammarFocus–4c1思考與討論：

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

2.主從句都用一般過去時(shí)態(tài)的時(shí)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(shí)間狀語從句中，主句和從句的動(dòng)作是同時(shí)發(fā)生，或者是在進(jìn)行一個(gè)動(dòng)作時(shí)，另外一個(gè)動(dòng)作突然發(fā)生。

2）主從句都用一般過去時(shí)態(tài)的時(shí)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(shí)態(tài)和一般過去時(shí)態(tài)在使用不同時(shí)態(tài)時(shí)從句和主句的動(dòng)作的先后順序。5過去完成時(shí)(1)構(gòu)成：由“助動(dòng)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(shí)表示在過去某一時(shí)間或動(dòng)作之前已經(jīng)發(fā)生或完成了的動(dòng)作。6(3)它所表示動(dòng)作發(fā)生的時(shí)間是“過去的過去”。①表示過去某一時(shí)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(shí)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(gè)動(dòng)作發(fā)生在另一個(gè)動(dòng)作前常常用過去完成時(shí)態(tài)。過去完成時(shí)的結(jié)構(gòu)過去完成時(shí)的用法過去完成時(shí)的否定形式過去完成時(shí)的疑問形式8過去完成時(shí)的判斷依據(jù):

由“過去的過去”來判定。

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

例：WhenIgottothestation,thetrainhadalreadyleft.

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