The Present Perfect Passive Voice
Aims:1. Understand the uses of the Present Perfect Passive Voice
2. Use the Present Perfect Passive Voice correctly 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。 现在完成时的被动语态The structure of the present perfect passive voice is:
have / has ＋ been＋~ed 主动语态即主语为动作的执行者；被
动语态即主语为动作的承受者。现在完
成时的被动语态同它的主动语态一样，
强调过去的动作对现在造成的影响或结
果，但主语为动作的承受者，表示“……
已经被……”。
The new school has been set up.
新学校已经建成了。2. 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需将have / has提到主语的前面。
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？现在完成时的被动语态表达以下两个
概念：
1. 说话时已经完成的动作或出现的结果。
2. 主语是行为动作的承受者。
现在完成时的被动语态由have/has been
＋v-ed构成，其中v-ed为过去分词，
表示被动。
I have been told about it many times．
The bridge has just been built．在使用现在完成时的被动语态时要
注意以下两点：
1. 过去分词前有两个助动词：
have / has和been。
2. 必须表示被动。 注意: 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
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。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.
How long has this book been bought?
How long ago was this book bought?(1) 把主动语态的宾语变为被动语态的主语。
(2) 把谓语变成被动结构 (be＋过去分词)
(根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。 主动语态变被动语态的方法(3) 把主动语态中的主语放在介词by之后作宾语, 将主格改为宾格。
All the people laughed at him.
He was laughed at by all the people.
They make the bikes in the factory.
The bikes are made by them in the
factory.(4) 双宾语动词变被动语态可将其中的一个宾语变为主语， 另一个保留不动。
主动：I have given him the key.
被动：He has been given the key.
被动：The key has been given (to) him.(5) 带复合宾语的动词变被动语态时, 只能将宾语变为主语, 原来的宾补保留不动， 改称主语补足语。
主动：I have asked her to help you.
被动：She has been asked to help you. 1. When and where to go for the
on-salary holiday ___ yet.
A. are not decided
B. have not been decided
C. is not being decided
D. has not been decided单选 2. Every possible means ___ to
prevent the air pollution, but the
sky is still not clear.
A. is used
B. are used
C. has been used
D. have been used 3. All the preparations for the task
___ and we’re ready to start.
A. completed
B. complete
C. had been completed
D. have been completed 4. Some new oilfields ___ since 1976.
A. were opened up
B. has opened up
C. have been opened up
D. had been opened up 5. The silence of the library ___ only
by the sound of pages being turned
over.
A. has been broken
B. breaks
C. broke
D. was broken 6. — ______ the sports meet might be
put off. — Yes, it all depends on the weather.
A. I’ve been told
B. I’ve told
C. I’m told
D. I told(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。试分析：(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。Homework 1. Try to remember the form of the Present Perfect Passive Voice.
2. Finish the exercise 3 on Page 21 and exercise 2 on page 57.
