(4)Soeventheolivewreath________________.就连橄榄枝花环也被取代了。二、现在完成时态的被动语态的用法:1.现在完成时的被动语态同它的主动语态一样,强调过去的动作对现在造成的影响或结果,通常与already,yet,just,never,recently等副词连用。*Theroomhasalreadybeencleaned.房间已经被清扫干净了。(意为“已不用清扫办公室了”)*Thedoctorhasn’tbeensentforyet.还没有派人去请医生。(意为“应派人去请医生”)*Theofficehasjustbeencleaned.办公室刚被打扫过。(意为“已不用清扫房间了”)*Suchathinghasneverbeenheardofbefore.这样的事以前从未听说过。(意为“现在才听说”)2.表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与for或since等引导的时间状语连用,或用于Howlong...?句型中。*Themachinehasbeenrepairedfortwohours.这台机器已修了两小时了。*(全国卷Ⅰ)Modernmethodsoftrackingpolarbearpopulationshavebeenemployedonlysincethemid-1980s.追踪北极熊数量的现代方法自从20世纪80年代中期才被采用。*Howlonghastheprojectbeencarriedout?这项工程已被实施多长时间了?【即学即练】(1)ProfessorJameswillgiveusalectureontheWesternculture,butwhenandwhere__________________yet.詹姆斯教授将要给我们作西方文化的演讲,但是时间和地点还没有决定。(2)Thewatch___just________________________.这只手表刚刚被清理和修理过。(3)_____theletters___________?信已经寄出去了吗?(4)______________themachine_____________?这个机器被修了多长时间了?注意：使用现在完成时的被动语态需要注意的问题:1.现在完成时的被动语态有两个助动词,即have/has和been,两者缺一不可。2.现在完成时的被动语态与一般过去时的被动语态的区别:一般过去时的被动语态表示一个被动的动作发生在过去某个时候,其结果对现在没有影响;而现在完成时的被动语态的动作或状态尽管发生在过去,但侧重说明该动作或状态对现在造成的影响和结果。*Thehousewasbuiltlastyear.这房子是去年建造的。*Thehousehasbeenbuilt.这房子已经建好了。3.由finish,buy,start,begin,post,return,borrow,join,marry,open等非延续性动词构成的现在完成时的被动语态不能与表示一段时间的状语如forfourdays,howlong等连用,而要改换动词或时态。但这类动词的否定式可表示动作的持续过程,具有延续性,因而可与since或for引导的时间段连用。例如：*这本书买了多久了?误:Howlonghasthisbookbeenbought?正:Howlongagowasthisbookbought?*Nobookshavebeenboughtsincelastweek.自上周以来,没有人来买过书。【即学即练】语法填空(1)Thebridge________(build)lastyear.

(2)Thecase_____________(try)recently.

(3)Greatchanges__________(take)placeinmyhometown.

(4)Sofar,manyvillages_______________(visit)
