factories

___B_____.

A. have been taken place

; have been set up B. have taken place; have been set up C. have taken place; have set up D. were taken place; were set up

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

What has happened to your brother? What was happened to your brother?

correct mistakes 1.The child has been taken good care of by Grandma all these years. 2.A notice has been put up 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，如上句中的of和up。

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。
