Passive voice
被动语态
被动语态 (Passive Voice)
结构: be + V-p.p.
am / are / is + 动词的过去分词
一般现在时的被动语态:
Many people speak English.
主动句与被动句之间的转换
English is spoken by many people.
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
Many people speak English.
主动句与被动句之间的转换
English is spoken by many people.
主语 谓语动词 宾语
主语 谓语动词的过去分词 介词+ 宾语
口诀:宾变主,主变宾,by短语后面跟。
谓语动词变被动,be+过分来使用。
被动语态由“助动词be+及物动词的过去分词”构成。与主动语态一样,被动语态也有时态、人称和数的变化, 其变化规则与be作为连系动词时完全一样。
二、被动语态的构成
肯定式 否定式 疑问式
一般 现在时 I am asked … He/She is asked … We/You/They are asked … I am not asked… He/She is not asked… We/You/They are not asked … Am I asked …
Is he/she asked …
Are we/you /they asked …
主动语态变被动语态的方法
A recorder is often used in our English class (by us).
1. 把主动语态的宾语变为被动语态的主语。
We often use a recorder in our English class.
宾语
主语
We often use a recorder in our English class.
谓语
2. 把谓语变成被动结构(be+过去分词)。
A recorder is often used in our English class
(by us).
一般现在时的被动语态
3. 把主动语态中的主语放在介词by之后作宾语,将
主格改为宾格,如主语是人称代词,一般省略。
We often use a recorder in our English class.
A recorder is often used in our English class
(by us).
4. 在主动语态句中动词make、have、let、see、watch、
hear、feel等后接动词不定式作宾语补足语,动词不
定式不加to。
但变成被动语态时后面的不定式都须加上to。
例如:
(1) The boss makes them work ten hours a day.
(2) Tom lets his little sister water flowers every
day.
→ They are made to work ten hours a day.
→ His little sister is let to water flowers every
day by Tom.

2. This shop uses the best materials to
make dresses.
________________________________
