例句
一般现在时的被动语态
am/is/are + done

一般过去时的被动语态
was/were + done

一般将来时的被动语态
will/be going to be + done

含情态动词的被动语态
情态动词 + be + done

3、 被动语态的用法
1. 不知道谁是动作的执行者,或不需要说明动作的执行者是谁时,用被动语态。如:
A new road will be built in Haikou city next month.
2. 强调动作的承受者时,用被动语态。如:
She is made to work for 20 hours by her boss every day.
3. 被动语态与不定式的特殊用法。
(1) 在主动句式中。感官动词和使役动词后的不定式作宾语补足语,要省去“to”
句式: sb. makes sb. do sth.
Mother always makes me feel happy.
(2) 在被动语态中,感官动词和使役动词后的不定式作宾语补足语,“to”不能省。
句式: sb. + be made(过去分词) + to do sth.
Tom was seen to go into the room just now.
(※ 口诀: 感使动词真叫怪, to来to去记心怀, 主动语态to离去, 被动语态to回来)
· 感官动词:see/ hear/ feel / watch / notice
使役动词:make / let / have (使,让)
4、 主动语态表被动意义的情况
1. 某些系动词(如:smell, look, taste, feel, sound等)描述某物特征时:
如: The cake tastes very delicious.
2. 动词open, read, sell. write等词作不及物动词,且它们的主语为物时:
如: The supermarket near my home open at 9 o’clock every day.
