被动语态 (Passive Vice)
结构: be + V-p.p.
am / are / is +动词的过去分词
was / were +动词的过去分词
一般现在时的被动语态:
一般过去时的被动语态:
Many peple speak English. (主动语态)
English is spken by many peple
The naughty by brke the windw yesterday. (主动语态)
The windw was brken ( by the naughty by) yesterday.
We bught sme bks.
主动句与被动句之间的转换
Sme bks were bught ( by us )
主语 谓语动词主动语态的过去式 宾语
主语 谓语动词被动语态的过去分词 介词+ 宾语
主动句变为被动句所遵循的4个步骤:
1. 把原主动句中的宾语变为被动句的主语。
2. 把动词变为被动形式即be+过去分词,并注意其人称和数随主语的变化,而动词的时态则保持不变。
3. 原主动句的主语如需要则放在by后面以它 的宾格形式出现(注代词的宾格),如不需要则可省略。
4. 其它的成分(定语、状语)不变。
Tm breaks the windw. (主动语态) ① ② ③The windw is brken by Tm. (被动语态) ③ ② ①
英语的谓语动词有两种语态
(前者表示句子的主语为动作的发出者,后者表示句子的主语为动作的承受者。)
从以上对比可以看出,主动句中的主语Tm在被动句中变成了短语by Tm,主动句中的宾语the windw变成了被动句中的主语。口诀:主变宾,宾变主,by短语后面跟, 谓语动词变被动, be 后过分来使用。
am/is/are dne
was/were dne
am/is/are being dne
was/were being dne
shall/will/be ging t be dne
wuld be dne
have/has been dne
had been dne
被动语态的几种特殊类型
如:1.He gave me a bk. -I was given a bk by him. -A bk was given t me by Tm. 2.He teaches us English. -We are taught English by him. -English is taught t us by him.
1.带双宾语句子的被动语态.
常见的接双宾语的动词有: t: pass, give, teach, shw, bring, hand fr: make, buy, draw, sing, get,
以“人”当主语时,变法和一般的变法一样;以“物”当主语时,在保留的间接宾语前必须加t或fr.
2.含有宾语补足语的句子的被动语态
keep, make 之类的动词常常有宾语补足 语,在被动语态中,宾语补足语位置不变。
We keep fd fresh in the fridge. 主 谓 宾 宾补
Fd is kept fresh in the fridge.
Tm made me angry.I was made angry by Tm.
即hear , listen , have , make , let , lk , watch , see , ntice ,这些词在主动句中,其后的动词不定式不加t,但变被动句时必须加t.
①.I saw him play basketball last Sunday.
t play basketball last Sunday.
②.We heard them sing in the classrm.
t sing in the classrm.
3.使役动词的被动语态
不及物动词没有宾语,因此没有被动语态。但有的不及物动词后面加上介词及其他一些词类构成短语动词之后,其作用相当于及物动词,可以接宾语,因而也可以变为被动语态。在变成被动语态时,不能去掉构成短语动词的介词或副词.
They take gd care f my child. I turned ff the radi.
4.含有短语的主动语态变被动语态
My child is taken gd care f .
The radi was turned ff (by me)
(1)当主动结构中的宾语是反身代词和each ther时,不能改为被动语态。 We ften help each ther. The man intrduced himself as Mr. White. (2)当谓语是表状态的及物动词时(如have , like , take place , belng t …) 如: I like these flwers. I will have a meeting. 不说A meeting will be had. 应说A meeting will be held .
5.不能用于被动语态的几种情况

1. They sld the fridge at a lw price. _______________________________
The fridge was sld at a lw price.
2. Smebdy stle my camera frm my htel rm. _________________________________ _________________________________
