Step 3

Grammar

现在完成时的被动语态

结构

肯定式

主语＋have/has been done... 否定式

一般疑问式

特殊疑问式

用法

主语＋have/has not been done... Have/Has＋主语＋been done...？

疑问词＋have/has＋主语＋been done...？

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, 其构成是: have/has been + done。如：

1. The dirty clothes have been washed.

脏衣服都已经洗了。

2. The plan has been studied by the experts for three times.

这项计划已经由专家研究过三次了。

3. The child has been taken care of by Grandma Wang all these years.

这些年来, 这个小孩一直由王奶奶照料。

【辨析】

现在完成时被动态：have / has + been + 动词过去分词

现在完成进行时：have / has + been + 动词现在分词

它们的构成的区别在最后的动词上, 被动态接的是过去分词形式, 现在完成进行时接的是现在分词形式。

1. 主语是行为动作的承受者。如：

The Temple of Zhang Fei has been rebuilt.

张飞庙已经过重建。

2. 说话时已经完成的动作或出现的结果。如: The door has been locked.

门已经被锁上了。

3. 动作或状态始于过去, 持续到现在, 并可能

持续下去。如：

He has been told about it for many times.

有人告诉他这事很多次了。

(可能还会有人告诉他) 4. 用在时间和条件状语从句中, 表示将来某时已完成的动作。如：

We’ll start as soon as the work has been finished.

工作一完成我们就立即动身。

【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。如：

[误] The door has been opened of itself.

[正] The door has opened of itself. 3. 短语动词不可分割或省略其中的介词或副词。如：

The SARS patients have been taken good care of. Step 4 Practice Step 5 Writing
