Grammar:

The Present Perfect Passive Voice 1. 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。

Understanding the structure of the present perfect passive voice The structure of the present perfect passive voice is: have / has ＋

been＋~ed

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。

1

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: 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。

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? 主动语态变被动语态的方法

(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)。
