Step6. Learn the usage of the grammar 1.现在完成时的被动语态同他的主动语态一样，强调过去的动作对现在造成的影响或后果already,yet, just, never, recently 等副词(常放在have或has之后)连用。The work has already been completed. 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引导的时间状语连用,或用于How long...?句型中My car has been repaired for two days. The house has been painted since the family moved out. 3. 用在条件状语从句中，表示将来某时已经完成的动作. We will start as soon as the work has been finished. 常用于现在完成时的句子中，since then /since +从句,so far, by now, up to now, recently, lately, already, yet, in/during the past/last + 段时间等。

注意：

1. 只有及物动词才有被动语态,不及物动词(词组)没有被动语态。

例如: happen, take place, die, appear, disappear, fail, remain, lie, last, sit, stand, break out, come true, belong to等

2. 但许多不及物动词加介词或副词构成的动词短语，相当于及物

动词，也可以有被动语态。但动词短语是一个不可分割的整体，变为被动语态时,不可丢掉构成短语的介词或副词。

3. 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。
