现在完成时的被动语态结构是“主语＋has/have＋been＋过去分词”。使用现在完成时的被动语态应注意下面几点：

1. 现在完成时的被动语态同主动语态一样强调过去的动作对现在的影响。

They have just cleaned and repaired the watch. → The watch has just been cleaned and repaired (by them).

Tom has written the letter．

→ The letter has been written by Tom．

分析：此表刚擦洗修理，那就必然是用现在完成时，my watch是动作的承受者，在被动语态句中作主语。

2. 被动语态没有完成进行时态，主动语态的现在完成进行时改为被动语态时要用现在完成时，依此类推，主动语态的过去完成进行时改为被动语态时用过去完成时。如：

He has been writing the report for two days. → The report has been written by him for two days.

3. 现在完成时的被动语态的用法

1) 表示一个被动的动作发生在说话之前,强调对现在造成的影响和结果。如: The door has been locked.门被锁上了。

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for或since引导的时间状语连用, 或用于How long...? 句型中。如: The important problem has been discussed for nearly two weeks. 那个重要的问题已经被讨论近两个星期了。

How long has the machine been used? 这机器使用有多久了?可。

3) 注意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情况的联系。如: The bridge was built last year. 这桥是去年建成的。

The bridge has been built.这桥已经建好了。

No books have been bought since last week.
