中考语法复习: 谓语动词语态
被动语态
一、语态
主动语态:表示主语是谓语动词的动作执行者。
被动语态:表示主语是谓语动词的动作承受者。
二、被动语态
1、构成:be + v.过去分词
(助动词be随着主语的人称、数、时态和语气的不同而变化)
Eg:He was hit by a car yesterday.
Football is enjoyed by people in the world.
2、各种时态的主动、被动语态的结构(以动词do为例)
时态
主动语态
被动语态
一般现在时
do/ does
am/ are/ is done
一般过去时
did
was/ were done
一般将来时
will/ be going to do
will/ be going to be done
现在完成时
have/ has done
have/ has been done
含情态动词
can/ should/ must/ may do
can/ should/ must/ may be done
3、用法
① 不知道或没有必要指出动作的执行者是谁。
Eg:The car is made in China.
② 需要强调或突出动作的执行者。
Eg:Chinese is spoken by the most people in the world.
③ 句子的主语是动作的承受者。
Eg: The book is written by Luxun.

A. plant B. are planted C. were planted D. will be planted
三、主动语态与被动语态的转换
1、主动语态变为被动语态
① 要将主句中的宾语成分变为被动句中的主语成分,若主动句中的宾语时人称代词,要讲宾格变成主格
② 把主动句中的主语变为被冻结中的宾语,主格变成宾格,并由by引导
③ 谓语动词变成相应的被动形式
Eg:We asked him to sing an English song.
He was asked to sing an English song by us.
2、带双宾语的谓语动词变为被动语态
Eg:She gave me a book.
I was given a book. (间接宾语me转变为主语)
A book was given to me by her. (直接宾语a book转变为主语)
口诀:如遇双宾语,一般变间宾,若把直宾变,to /for 间宾连。
3、动词短语变为被动语态
不及物动词和介词、副词构成的动词短语,在变为被动语态时,不可丢掉构成动词短语的介词或副词。
Eg:We should speak to the old man politely.
The old man should be spoken to politely by us. (其中,to不可省略)
4、带复合宾语的动词变为被动语态
宾语加上宾语补足语一起构成的复合宾语,变被动语态时,只需把宾语变为被动句的主语,宾语补足语保留的原处,成为主语补足语。
Eg:I heard Jane playing the piano in her room.
Jane was heard playing the piano in her room.
5、被动语态后动词形式的选择
主动句中在感官动词see,hear,watch,feel,notice等以及使役动词let,make,have等后面跟省略to的不定式,变为被动语态时,to需还原。
Eg:He makes the girl stay at home.
The girl was made to stay at home.
