A.mustn’thavehurriedB.couldn’thavehurried

C.mustnothurry

D.needn'thavehurried典型例題38精選課件ppt答案D。needn’thavedone.意為“本不必”,即已經做了某事,而實際上不必要。mustn’thavedone用法不正確,對過去發(fā)生的事情進行否定性推斷應為couldn’thavedone,“不可能已經”。mustnotdo不可以(用于一般現在時)39精選課件ppt三.虛擬語氣假設條件句型注意點:1.假設條件從句謂語動詞發(fā)生的時間與主句所假設的謂語動詞不一致,叫做錯綜條件虛擬語氣。主句和從句的謂語動詞要依照假設的時間而定。40精選課件pptIftheweatherhadbeenfiner,thecropswouldbegrowingstillbetter.Ifyouhadfollowedtheteacher’sadvice,youwouldn’tbeinthehospital.41精選課件ppt2.假設條件虛擬倒裝。條件從句中有should,were,had三個助動詞可以把if省略,并將這三個詞提至句首。

shouldhavefinished

yourhomeworkyesterday.2)You

shouldhavecome

herefiveminutesearlier.3)He

shouldhavetold

meaboutitearlier.44精選課件ppt注意：

在虛擬語氣的從句中,動詞be的過去時態(tài)一律用were,不用was,即在從句中be用were代替。45精選課件pptIfIwereyou,Iwouldgotolookforhim.如果我是你,就會去找他。Ifhewerehere,everythingwouldbeallright.如果他在這兒,一切都會好的。46精選課件ppt_____todothework,Ishoulddoitsomeotherday.

A.IfwereIB.IwereC.WereID.WasI典型例題47精選課件ppt答案C.注意:在虛擬條件狀語從句中,省略連詞的倒裝形式的句首不能用動詞的縮略形式。如我們可說WereInottodo,而不能說Weren’tItodo.48精選課件pptExercisesI1.You___tothemeetingyesterday.Whatwasthereasonforyourabsence?A.hadcome B.cameC.wouldhavecome D.shouldhavecome2.“HaveyouvisitedtheScienceMuseum?”“No,butIreallywishI___.”A.had B.did C.have D.will49精選課件ppt3.Hereissomemoneyincaseyou___it.A.needsB.needC.neededD.willneed4.Hedemandedthattheclassroom___atonce.A.shouldclean B.cleanC.shouldhavebeencleanedD.becleaned50精選課件ppt5.Butforyourcarelessness,we___.A.shouldhavesucceededB.hadsucceededC.wouldhavesucceededD.succeeded51精選課件ppt6.Whenapencilispartlyinaglassofwater,itlooksasifit_____.
