has/have been done现在完成时 被动语态现在完成时的被动语态

Page 53: Unit 3 Computers

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

Understanding the structure of the present perfect passive voiceThe structure of the present perfect passive voice is: have / has + been+~ed

Page 54: Unit 3 Computers

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.

Page 55: Unit 3 Computers

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.

Page 56: Unit 3 Computers

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.

Page 57: Unit 3 Computers

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:

Page 58: Unit 3 Computers

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?

Page 59: Unit 3 Computers

(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

Page 60: Unit 3 Computers

(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。例如:  All the people laughed at him.  He was laughed at by all people.  They make the bikes in the factory.  The bikes are made by them in the factory.

Page 61: Unit 3 Computers

(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.

Page 62: Unit 3 Computers

(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.
