被动语态专题
一、被动语态的定义
当主语为动作的执行者时,谓语的形式为主动语态;当主语为动作的承受
者时,谓语要用被动语态。
e.g. Many people speak English.
(主动语态,句子的主语many people 是动作speak 的执行者)
English is spoken by many people.
(被动语态,句子的主语many people 是动作speak 的承受者)
二、被动语态的构成
1. 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 作为系动词时完全
一样。

构成
例句
一般现在时
am, is, are+done
Trees are planted in spring.
一般过去时
was, were+done
The house was built last
year.
一般将来时
will be+done, be going to
be+done
Lei Feng will be remembered
by us forever .
现在进行时
be+being+done
The car is being repaired.
过去进行时
was/were+being+done
My car was being repaired at
10 am yesterday.
现在完成时
have/ has been+done
The light has been turned
off.
过去完成时
had been+done
/
情态动词
can, may, must be+done
My
homework
can
be
finished on time.
2. 被动语态常用于以下场合:
①不知道或没有必要说明动作的执行者是谁时。如:My bike was stolen
yesterday .我的自行车昨天被偷了。
②强调动作的承受者时,如果需要突出动作的执行者,用“by +动作的执
行者”。如:The pen was used by
my
father
.这支钢笔是我父亲用过的。
※ 只有及物动词才有被动形式,不及物动词如rise / come / go / take /
place / happen 等,没有被动形式。

三、主动语态变被动语态的步骤
通常遵循以下三个步骤:
1.把主动语态的宾语变成被动语态的主语。
2.把主动语态的谓语动词变为与其时态相对应的被动形式,且与被动语态的
主语保持人称和数的一致。
3.将主动语态的主语变为介词by 的宾语,置于句末。“by +宾语”在句中常
省略。
四、主动语态和被动语态的转换
1.双宾语的被动形式
双宾语的句子在变为被动语态时,有两种变法:
(1)如果把指人的间接宾语变为主语,那么指物的直接宾语保留不动。
如: His teacher gave him a book .→He was given a book by his teacher .
He has bought me a present .→I have been bought a present .
(2)如果要将指物的直接宾语变为主语,那么动词后要用介词to / for,这
个介词是由与其搭配的动词决定的。如:
His teacher gave him a book.→A book was given to him by his teacher.
He has bought me a present.→A present has been bought for me.
※ 常见的能接双宾语的动词有give / show / bring / lend / send 等,这
些词与介词to 搭配;buy / make / draw 等,这些词与介词for 搭配。
2.动词短语的被动语态
许多不及物动词加上介词或副词后构成的短语动词相当于及物动词,是一
个不可分割的整体,在变为被动语态时不能把短语动词分开,也不能漏掉短语
动词中的介词或副词。 如:
①We should speak
to old men politely .→Old men should be spoken to
politely .
②He always takes
care
of
his sister .→His sister is always taken care of (by
him).
③She turned
off
the radio .→The radio was turned off (by her).

3. 省略to 的动词不定式用于被动语态
在主动语态中,一些表示感官或使役的动词,如hear / watch / see / feel
/ notice / listen to / look at / let /make / have 和help 等后面的宾语补足语
是不带to 的动词不定式,但句子在变为被动语态后要加to。如:
①
He made the girl stay at home .→The girl was made to stay at home .
②
We often hear her sing in the room .→She is often heard to sing in the
room .
③
The boss made them work for 16 hours a day .→They were made to
work for 16 hours a day (by the boss).
4. 主动形式表被动意义
① 动词need,want 以及短语be(well)worth 等后面常接动名词,以主
动形式表示被动意义。如:
The room needs cleaning.这房子需要打扫。
The piece of music is worth listening to.这首曲子值得听。
② 某些表示主语质地、自身特征的动词,如write / wash / sell / clean /
cook 等,常和副词well 或easily 连用,用主动形式表示被动意义。如:
The cloth washes easily .这种布容易洗。
The pen writes well .这支笔很好用。
