现在完成时的被动语态的用法
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。
The machine has already_____________________(repair)．机器已经修好了。
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fr或since引导的时间状语连用，或用于“Hw lng ．．．？”句型中。
Financial prblems f the cmpany ___________________________(discuss) fr nearly tw hurs．
3．用在时间或条件状语从句中，表示将来某时已完成的动作，即用现在完成时的被动语态代替将来完成时的被动语态。
Yu shuldn’t leave schl befre yur hmewrk ___________________________(finish)
※使用现在完成时的被动语态要注意的问题:
1．现在完成时的被动语态、现在进行时的被动语态及一般过去时的被动语态的区别
The machine has been repaired.(说明动作发生在过去，对现在________________，“现在修好了”)
The machine is being repaired nw.(说明动作____________进行)
The machine was repaired yesterday.(只说明动作发生在____________)
2．非延续性动词，如brrw, finish, begin, start, buy, marry, pen, jin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，例如：
工程已开始三个月了。
判断正误：
The prject has been started fr three mnths.( ____________)
The prject has been n fr three mnths. (____________)
3.带有复合宾语的动词变为被动语态时，若宾语补足语为省略t的不定式充当时，在被动语态中需将省掉的t加上。
The bss has made his cmpany ffer mre chances fr peple t wrk.
→_______________________________________________
(4)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。
It's said that the prblem has____________________________(lk int).据说已经调查了这个问题。
