(4)Soeventheolivewreath________________.就連橄欖枝花環(huán)也被取代了。二、現(xiàn)在完成時(shí)態(tài)的被動(dòng)語態(tài)的用法:1.現(xiàn)在完成時(shí)的被動(dòng)語態(tài)同它的主動(dòng)語態(tài)一樣,強(qiáng)調(diào)過去的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果,通常與already,yet,just,never,recently等副詞連用。*Theroomhasalreadybeencleaned.房間已經(jīng)被清掃干凈了。(意為“已不用清掃辦公室了”)*Thedoctorhasn’tbeensentforyet.還沒有派人去請(qǐng)醫(yī)生。(意為“應(yīng)派人去請(qǐng)醫(yī)生”)*Theofficehasjustbeencleaned.辦公室剛被打掃過。(意為“已不用清掃房間了”)*Suchathinghasneverbeenheardofbefore.這樣的事以前從未聽說過。(意為“現(xiàn)在才聽說”)2.表示一個(gè)被動(dòng)的動(dòng)作或狀態(tài)開始于過去,持續(xù)到現(xiàn)在,并可能持續(xù)下去,常與for或since等引導(dǎo)的時(shí)間狀語連用,或用于Howlong...?句型中。*Themachinehasbeenrepairedfortwohours.這臺(tái)機(jī)器已修了兩小時(shí)了。*(全國卷Ⅰ)Modernmethodsoftrackingpolarbearpopulationshavebeenemployedonlysincethemid-1980s.追蹤北極熊數(shù)量的現(xiàn)代方法自從20世紀(jì)80年代中期才被采用。*Howlonghastheprojectbeencarriedout?這項(xiàng)工程已被實(shí)施多長(zhǎng)時(shí)間了?【即學(xué)即練】(1)ProfessorJameswillgiveusalectureontheWesternculture,butwhenandwhere__________________yet.詹姆斯教授將要給我們作西方文化的演講,但是時(shí)間和地點(diǎn)還沒有決定。(2)Thewatch___just________________________.這只手表剛剛被清理和修理過。(3)_____theletters___________?信已經(jīng)寄出去了嗎?(4)______________themachine_____________?這個(gè)機(jī)器被修了多長(zhǎng)時(shí)間了?注意：使用現(xiàn)在完成時(shí)的被動(dòng)語態(tài)需要注意的問題:1.現(xiàn)在完成時(shí)的被動(dòng)語態(tài)有兩個(gè)助動(dòng)詞,即have/has和been,兩者缺一不可。2.現(xiàn)在完成時(shí)的被動(dòng)語態(tài)與一般過去時(shí)的被動(dòng)語態(tài)的區(qū)別:一般過去時(shí)的被動(dòng)語態(tài)表示一個(gè)被動(dòng)的動(dòng)作發(fā)生在過去某個(gè)時(shí)候,其結(jié)果對(duì)現(xiàn)在沒有影響;而現(xiàn)在完成時(shí)的被動(dòng)語態(tài)的動(dòng)作或狀態(tài)盡管發(fā)生在過去,但側(cè)重說明該動(dòng)作或狀態(tài)對(duì)現(xiàn)在造成的影響和結(jié)果。*Thehousewasbuiltlastyear.這房子是去年建造的。*Thehousehasbeenbuilt.這房子已經(jīng)建好了。3.由finish,buy,start,begin,post,return,borrow,join,marry,open等非延續(xù)性動(dòng)詞構(gòu)成的現(xiàn)在完成時(shí)的被動(dòng)語態(tài)不能與表示一段時(shí)間的狀語如forfourdays,howlong等連用,而要改換動(dòng)詞或時(shí)態(tài)。但這類動(dòng)詞的否定式可表示動(dòng)作的持續(xù)過程,具有延續(xù)性,因而可與since或for引導(dǎo)的時(shí)間段連用。例如：*這本書買了多久了?誤:Howlonghasthisbookbeenbought?正:Howlongagowasthisbookbought?*Nobookshavebeenboughtsincelastweek.自上周以來,沒有人來買過書。【即學(xué)即練】語法填空(1)Thebridge________(build)lastyear.
