C.having D.tobewhenalotofpeoplewerequestionedforviewsabouttheaccident,theysaidthatthecausewascarelessness.补全句子的forfearthatsbshoulddo的结构,如果Theboyhidhimselfbehindthetreeforfearthathisfathershouldseehim那么在做题过hadgotupearlier,hewouldnothavemissedthemeeting那么就会知道if从句对过去的虚拟结构是从句用haddone,主句用情态动词加havedone。if的虚拟语气有混淆的情况,自己如果按照例句法记忆,注意不要死记硬背,注意灵活变化,看清句子中的时间 apostoffice,I someA.Passed,buyingB.Passing,tobuyC.Havingpassed,buyD.Pass,toIpassedapostoffice,Istoppedtobuysomestamps。可以得出答案B。 withthesizeofthewholeearth,thehighestmountaindoesnotseemhighatA. B.To C. D.Havingdoesnotseemhighatall.有补全的句子可以看出,从句中是被动,所以选择答案C。方法总结:状语从句和非谓语动词在省略中结合是非常紧密的,学生在做题过程中可以将平时所学的两种语法知识howtodothehomework,IwenttoaskmyteacherforA.Notto B.Not C.Knowing D.NotknowIBecauseIdidn’tknowhowtodothehomework,Iwenttoaskmyteacherforhelp.因而前面动作不存在将来,选择B。 ,IthankedheragainandA.being B. C. D.tobeBecauseIwasdeeplymoved,Ithankedheragainandagain采用状语从句的省略原则,省略主语和谓语动词be,即得出答案B。manytimes,hestillcouldn’tA.HavingbeentoldB.HavingtoldC.Hehavingbeen D.Thoughhehadbeentoldmanytimes,hestillcouldn’tunderstand,因而tellfromthetopofthetower,thesouthfootofthemountainisaseaofA. B. C.Having D.ToWhenitisseenfromthetopofthetower,thesouthfootofthemountainisaseaoftrees.根据状语从句的省略原则,可以得出答案是A。 withnumbers,thebookscanbeeasilyA. B. C.to D.Whenthebooksareproperlymarkedwithnumbers,theycanbeeasilyfound.同样可以得出答案A。itistherebe
