的被动语态通常有以下两种情况:表示过去开始的被动动作一直持续到现在,常与之连用的时间状语有:for+一段时间,since+时间状语(从句),thesedays,sofar,uptonow,inthelast/pastfewyears等。表示某被动
动作对现在造成的影响或结果,常与already,yet,just,ever,never,recently等连用。e.g.Thebikehasnotbeenrepairedyet.Ihavealreadybeenintroduce
dtoMr.Smith.Step4:【注意】1)现在完成时被动语态的两个助动词:have/has和been缺一不可。2)注意与一般过去时被动语态的区别。一般过去时被动语态表示一个被动的动作发生在过去,其结果对现在没有影响;而现在完成时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或结果。3)动词短语是一个不可分割的整体,在被动语态中要保持其完整性,其中的介词或副词不可省略。e.g.Theorphanshavebeentakengoodcareofhere
.孤儿们在这里受到很好的照顾4)并不是所有动词都有被动语态happen,takeplace,breakout,belongto,cost,last等不及物动词或词组无被动语态。[误]GreatchangeshavebeentakenplaceinChinasince1978.[正]Grea

iceofthepresentperfecttenseChinasince1978.5)一些特殊动词,如borrow,finish,begin,buy,start,return,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,则需改换动词或时态。6)只带有一个宾语的动词变为被动语态时,将主动语态的宾语变为被动语态的主语。e.g.Wehavebuiltmanyhousesinthepasttenyears.→Manyhouseshavebeenbuiltinthepasttenyears.7)带有双
宾语的动词,如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,tell,pay,lend,pass,promise等,变为被动语态时,可将其中一个宾语变为主语,另一个保留不动
。e.g.Wehavegivenhimthebook.→Hehasbeengiventhebook.→Thebookhasbeengiventohim.8)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。原来省略to的不定式作宾补的,被动语态中要用带to的不定式。e.g.Ihavetoldthemtohelpyou.→Theyhavebeentoldtohelpyou.Ihavemadeherworkhard.→Shehasbeen
