The present perfect passive voice

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。如：

All the people laughed at him.

He was laughed at by all people. (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. (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. **补充：不用被动语态的动词：

①

不及物动词（vi.) 如: happen, take place, appear, disappear , etc. A traffic accident happened just now.

②连系动词（Link.v.) 如：be, look, seem, feel, sound, smell, taste, get, turn, become, etc. ③当此动词表示事物的自然属性的时候：

The pen writes very fast.

This kind of sweater sells well. ④open, break, drop等不强调动作发出者时常用主动语态。

StepⅣ Exercise-in-class 1.用所给动词的适当形式填空

1)This kind of bike ________(sell) in the New Century Supermarket. It _______(sell) well. 2) An accident ___________(happen) here last week.

3) So far, many man-made satellites _______________(send) up into the space. 4) Many books on science _________________ (buy) since I went to college. 5) She

(tell) about it yet.. 6) The People’s Republic of China _________ (found) on October1, 1949. 2.将下列句子变为被动语态。

1) We have planted some trees around the lake.

2)They produce silk in Suzhou.

3) Tom has locked the door.

4) Mr. Li introduce me to everyone.

5. My brother often mends his watch.

6) They have sold out the light green dresses.

7)You can dig a hole in the earth.
