现在完成时的被动语态
一、现在完成时的被动语态的构成
二、现在完成时的被动语态的用法
1.表示一个被动动作发生在说话之前,强调对现在造成的影响和结果。
The house has been cleaned by my home robot.
房子已经被我的家庭机器人打扫干净了。
All the preparations for the task have been completed.

More than 20,000 computers have been made in the factory since last month.
自从上个月起,这个工厂已生产了20 000多台电脑。
三、短语动词的被动语态
1.短语动词是一种固定的词组,由“动词+副词”或“动词+副词+介词”构成,其作用相当于一个动词。
(1)“及物动词+副词”“及物动词+介词”以及“及物动词+副词+介词”构成的短语动词可用于被动结构。
At last they put out the fire.→At last the fire was put out.
Have you sent for a doctor?→Has the doctor been sent for?
My classmates caught up with me in this exam.→I was caught up with by my classmates in this exam.
(2)许多“不及物动词+介词”以及“不及物动词+副词+介词”构成的短语动词相当于及物动词,也可以有宾语,也可用于被动结构。
The boys laughed at him for the foolish mistake.→He was laughed at for the foolish mistake.
注意:短语动词是一个不可分割的整体,在变为被动语态时,不可丢掉构成短语动词的介词或副词。
We must take good care of the young trees.
→The young trees must be taken good care of.
2.带有双宾语的句子在变为被动结构时,这两个宾语的任何一个都可作被动句的主语。
(1)把间接宾语改为被动语态的主语,直接宾语仍保留原位。
(2)把直接宾语改为主动语态的主语,此时,间接宾语前要加介词to或 for。
He gave the boy an apple.
→The boy was given an apple./An apple was given to the boy.
Her father bought her a present.
→She was bought a present by her father./A present was bought for her by her father.
3.带复合宾语的动词在改为被动语态时,一般把主动语态的宾语改为主语,宾语补足语在被动语态中作主语补足语。
We call him Xiao Wang.→He is called Xiao Wang.
He cut his hair short.→His hair was cut short.
注意:
主动语态中不带to的动词不定式作宾语补足语,改为被动语态时不定式前要加to。
They watched the children sing that morning.
→The children were watched to sing that morning.
