主动语态：主语是动作的发出者Tm swept the flr.被动语态：主语是动作的承受者The flr was swept by Tm.
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 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
肯定句：主语＋be + 过去分词＋(by ~)否定句：主语＋be nt ＋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的方法
by the teacher.
3.The teacher ften asks him questins.
1.把主动语态的宾语变为被动语态的主语
2.把主动语态的谓语变为被动语态的谓语
3.把主动语态的主语变为被动语态的by 短语。（① by短语可以省。② by短语 后跟代词的宾格。）
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 gd care f my child. My child is taken gd care f .I turned ff the radi. The radi was turned ff (by me)
1.含有短语的主动语态变被动语态
1.Plicemen 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 f －be taken care f cut dwn －be cut dwn laugh at －be laughed at lk after－be lked 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 sn a ty . 间接宾语 直接宾语 His sn was given a ty.A ty was given t him. Tm bught his mther a flwer. 间接宾语 直接宾语 His mther was bught a flwer.A flwer was bught fr his mther.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: t, fr.
pass, shw, send…
be bught fr
be given t
draw，make, ck, mend，rder
Mther made me a cake . (变成被动语态）Lucy passed Tm an apple.(变成被动态）
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.
（口诀二：主动句中t 离开，被动句中t 回来）
3.感官动词和使役动词的被动语态
feel,hear,listen,have,make,let,lk,watch,see,ntice 这些词在主动句中，其后动词不定式不加t,但变被动句时必须加t.
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 ften help each ther. 我们常常互相帮助。
(把下列句子变成被动态）The bss made him wrk 14 hurs a day .We ften 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 nw.2. 连系动词 如：be, lk, seem, get, turn, becme…The trees _____ (turn) green.
3.感官动词 ( taste ; feel ; smell ; sund ; lk ) 用主动形式表示被动。 Hw sweet the music sunds ! Gd medicine tastes bitter t the muth .4.当以下动词表示事物的自然属性的时候: write、read、sell、keep、prve、weigh、number、drink、wear、pay、wash、pen常用主动形式表被动意义。尤其是有副词 well, easily时。 The bk sells well . ( 这本书销路很好。 ) The dr will nt pen . ( 这扇门就是打不开。 ) This dress washes better . ( 这衣服较好洗。 ) The sign reads as fllws . ( 这牌子告示如下。 )
特殊情况 （考试重点 ）
5.need, demand, want(需要）, require, be wrth等后用动名词表被动。 The desk needs repairing. The nvel is wrth 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 t be repaired.
6.have sth dne 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 ne day he climbed t the tp f a huse and据说…It was reprted that her mther died f SARS. 据报道……记忆下列句型：众所周知… … It is well knwn that …据推测说… … It is suppsed that …大家相信…… It’s believed that …大家希望…… It’s hped that …大家认为…… It’s thught that …据建议…… It’s suggested that …
用所给词的适当形式填空
1.A traffic accident ________(happen) just Opera ________ (sund) pen __________(write) very ’s _______(think) that Chinese is very hair needs ______(wash).6.I will have my hair _____(wash) this evening.难点: They will have a meeting . A meeting will be held by them
