【语法感悟】
1.现在完成时的主动形式为“___________________”,强调过去的动作对现在的影响或结果。比如句(3)中which引导的非限制性定语从句。
2.现在完成时的被动形式为“___________________________”,也是强调过去的动作对现在造成的影响或结果。如句(1),句(2),句(3),句(4)和句(6)。
have/has done
have/has been done
语法精讲

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.
这项任务的所有准备工作都已完成。

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.
