Unit 3 Grammar
The Present Perfect Passive Voice

现在完成时的被动语态 现在完成时的被动语态表示动作发生在过 去, 到现在已经完成或对现在仍有影响。
The structure of the present perfect passive voice is: have / has + been+V-ed

现在完成时被动语态的肯定式为: have / has + been + done
The experiment has been done successfully. 这个实验做得很成功。
现在完成时被动语态的否定式为: have / has + not + been + done Tom’s novel has not been published. 汤姆的小说还没有被出版。

现在完成时被动语态的一般疑问句: Have / has + 主语+been done Has his bike been repaired? 他的自行车修好了吗?
现在完成时被动语态的特殊疑问句为: 疑问词 + have / has + been + done Who has been invited? 谁受到了邀请?

注意:
1. 副词的位置
often, usually, always, never, hardly, seldom等副词置于have / has和been中间。 如: [误] Such a man has been hardly
believed. [正] Such a man has hardly been
believed.

2. 并不是所有动词都有被动语态 (1) happen, take place, break out, belong
to, cost, last等不及物动词或词组无被 动语态。如: [误] Great changes have been taken
place in China since 1978. [正] Great changes have taken place in
China since 1978.

(2) open, break, drop等不强调动作发出 者时常用主动语态。
The door has opened of itself. 门自动开了。 3. 短语动词不可分割或省略其中的介词 或副词。如:
The patients have been taken good care of.

4. 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:
My brother has had (不能用has bought)
this bike for almost four years.

试分析:
(1)[误]Many new buildings been built since 1980.
[正]Many new buildings have been built since 1980.
分析: 谓语部分结构不全, 时态部分不完整。

(2)[误]Something bad has been
happened to him. [正]Something bad has happened to
him. 分析: 被动语态误用。happen为不及物动 词,不及物动词没有被动语态。
(3)[误]I have introduced to Mr Smith. [正]I have been introduced to Mr
Smith (by Mr Wang). 分析: introduce为及物动词,I是introduce 的承受者。

(4)[误]The door has been opened of
itself. [正]The door has opened of itself. 分析: 有些动词如open,break,drop等 既可以作及物动词,又可以作不及物动 词,若不强调谁是动作的发出者,我们 通常用主动语态。of itself意思是“自动 地”,因此,此句不可用被动语态。
