STEP 2现在完成时的被动语态

Understanding the structure of the present perfect passive voice

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

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。

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.

STEP3现在完成时的被动语态

肯定结构：

have / has + been + done

否定结构：

have / has + not + been + done
