Step 3 Grammar -----The Present Perfect Passive Voice 现在完成时被动语态的肯定式为：have / has + been + done The task has been done successfully.

现在完成时被动语态的否定式为：

have / has + not + been + done Mary’s novel has not been published.

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 computer been repaired?

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?

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 machine has just been built．

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)。

(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 her.

She was laughed at by all the people.

They make the desks in the factory.

The desks 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 book.

被动：He has been given the book. 被动：The book 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.
