被动语态的构成
被动语态由“助动词be＋及物动词的过去分词”构成。
助动词Be的变化是通过人称、数和时态的变化表现出来的。
am/is/are done
was/were done
am/is/are being done
was/were being done
shall/will/be going to be done
would be done
have/has been done
had been done
时态 被动语态结构

一般过去时

肯定句：主语＋be + 过去分词＋(by ~)

否定句：主语＋be not ＋过去分词＋(by ~)

一般疑问句：Be ＋主语＋过去分词＋(by ~)?

特殊疑问句：
疑问词＋be＋主语＋过去分词＋ (by ~)

主动语态变被动语态口诀（一）

宾语提前主语变，

主变宾by后见，

时态人称be关键。
主动语态变被动语态的几种特殊情况
（中考重点）
1.动词+介词
2.动词带有双宾语的句子
3.谓语动词是感官动词和使役动词
4.宾语是反身代词和相互代词
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 good care of my child.
My child is taken good care of .
I turned off the radio.
The radio was turned off (by me)
1.含有短语的主动语态变被动语态
1.Policemen ran after the thief.(变成被动语态）

2.The girl is playing with a pet . (变成被动语态）

注意以下动词短语的被动语态结构
take care of －be taken care of
cut down －be cut down
laugh at －be laughed at
look after－be looked after


2.带双宾的谓语动词有两种改法。
1.把间接宾语改成主语：
He gave his son a toy .
间接宾语 直接宾语
His son was given a toy.
A toy was given to him.
Tom bought his mother a flower.
间接宾语 直接宾语
His mother was bought a flower.
A flower was bought for his mother.
2.把直接宾语改成主语时，谓语动词后必当须加适当的介词: to, for.


pass, show, send…
此类动词有：
buy
be bought for
如：give
be given to
此类动词还有：
draw，make, cook, mend，order
Mother made me a cake . (变成被动语态）

Lucy passed Tom an apple.(变成被动态）

1.I saw him play basketball last Sunday.
He
was seen
to play basketball last Sunday.
2.We heard them sing in the classroom.
They
was heard
to sing in the classroom.
（口诀二：主动句中to 离开，被动句中to 回来）
3.感官动词和使役动词的被动语态
feel,hear,listen,have,make,let,look,watch,
see,notice 这些词在主动句中，其后动词不定式不加to,但变被动句时必须加to.
4.当主动结构中的宾语是反身代词和相互代词时，不能改为被动语态。
We often help each other.
我们常常互相帮助。
(把下列句子变成被动态）
The boss made him work 14 hours a day .

We often hear him speak English .
不用被动语态的几种情况
1. 不及物动词 如:die, happen, take place, appear, disappear, …
A traffic accident _happened__(happen) just now.
2. 连系动词 如：be, look, seem, get, turn, become…
The trees _____ (turn) green.
turn
3.感官动词 ( taste ; feel ; smell ; sound ; look ) 用主动形式表示被动。
How sweet the music sounds !
Good medicine tastes bitter to the mouth .
4.当以下动词表示事物的自然属性的时候:
write、read、sell、keep、prove、weigh、number、drink、wear、pay、wash、open常用主动形式表被动意义。尤其是有副词 well, easily时。
The book sells well . ( 这本书销路很好。 )
The door will not open . ( 这扇门就是打不开。 )
This dress washes better . ( 这衣服较好洗。 )
The sign reads as follows . ( 这牌子告示如下。 )
特殊情况 （考试重点 ）
5.need, demand, want(需要）, require, be worth等后用动名词表被动。
The desk needs repairing.
The novel is worth seeing.
注意：need后可接动名词表被动，又可接动词不定式的被动形式。
比较 :The desk needs repairing.
The desk needs to be repaired.
6.have sth done 主动语态表达被动意义
I had my hair cut last night.
汉语中含有“据说”、“据悉”、“有人说”、“大家说”等时。
It is said that one day he climbed to the top of a house and据说…

据推测说… … It is supposed that …
大家相信…… It’s believed that …
大家希望…… It’s hoped that …
大家认为…… It’s thought that …

用所给词的适当形式填空

2.Peking Opera ________ (sound) beautiful.
3.The pen __________(write) very fast.
4.It’s _______(think) that Chinese is very hard.
