被动的动作在说话之前已经完成,强调过去的动作对现在造成的影响或产生的结果。通常与already,yet,never,recently等副词及时间状语sofar,bynow,uptillnow,before...等连用。Theworkhasalreadybeen
finished.工作已完成了。(结果是现在不用做这项工作了)Thedoctorhasn'tbeensentforyet.还没有派人去请医生。(现在应派人去请医生)栏目导航栏目导航92.表示一个被动的动作或状态开始于过

e).hasbeenchangedhavebeenproduced栏目导航栏目导航12四、使用现在完成时的被动语态要注意以下几点1.与一般过去时的被动语态的区别一般过去时的被动语态所表示的动作或状态与现在的情况没有联系,而现在完成时的被动语态则强调与现在的情况有联系。Theparkwa
sopenedtothepubliclastyear.去年这家公园向公众开放。(说明动作发生于过去)栏目导航栏目导航13Theparkhasbeenopenedtothepublic.这家公园已向公众开放。(说明动作发生于过去,
但对现在有影响,即现在公园已经开放了)栏目导航栏目导航142.非延续性动词如borrow,finish,begin,start,buy,marry,open,join等构成的现在完成时的被动语态不能与表示一
段时间的状语连用。若要表达相应的意思,则要改换动词或时态。Theworkwasfinishedtwoweeksago.这项工作在两周前已经完成。Theworkhasbeenfinished.这项工作已经完成。栏目导航栏目导航153.动词短
语动词短语是一个不可分割的整体,在被动语态中要保持完整性,其中的介词或副词不可省略。Itissaidthattheproblemhasbeenlookedinto.据说已经调查了这个问题。栏目导航栏目导航164.带有复合宾语的动词变为被动语态时,只能将宾语变为主语,原来
的宾补改为主语补足语。注意:原来作宾补的省略to的不定式在被动语态中要用带to的不定式。Ihavetoldthemtohelpyou.→Theyhavebeentoldtohelpyou.栏目导航栏目导航17
5.带有双宾语的动词如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,pay,lend,pass,promise等,变为被动语态时,一般将间接宾语变为被动语态的主语,若将直接宾语变为被动语态的
主语时,间接宾语前面要用相应的介词。栏目导航栏目导航18Thecompanyhasgivenhimachancetoworkabroadrecently.→Hehasbeengivenachancetowork
