2.A notice has been put on the wall.
但许多不及物动词加介词或副词构成的短语
动词，相当于及物 动词，也可以有被动语态。但短语动词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。correct mistakesofup二、现在完成时的被动语态应注意的几个问题
? 1.请注意现在完成时的被动语态的两个助动词,即have/has和been,两者缺一不可。
2. 请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.
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。3.请注意一些特殊动词,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。如:
[误] How long has this book been bought?
[正] How long ago was this book bought?
但这类动词的否定式可表示动作的持续过程,具有连续性,因而可与since或for引导的时间状语连用。如:
No books have been bought since last week.
自上周以来,没有人来买过书。
