初中英语被动语态用法小结[1]
一、语态概述
英语的语态是通过动词形式的变化表现出来的。英语中有两种语态:主动语态和被动语
态。
主动语态表示主语是动作的执行者。
例如:Many people speak
Chinese.
谓语:speak的动作是由主语many people来执行的。
被动语态表示主语是动作的承受者,即行为动作的对象。例如:Chinese is
spoken by
many people. 英语English是动词speak的承受者。
二、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
。人称、数和时态的变化是通
过be的变化表现出来的。现以speak为例说明被动语态在各种时态中
的构成。
一般现在时:am/isare+spoken
一般过去时:was/were+spoken
一般将来时:will/shall
be+spoken
现在进行时:am/is/are being+spoken
过去进行时:waswere being+spoken
现在完成时:have/has been+spoken
过去完成时:had been
+ spoken
三、被动语态的用法
(1)不知道或没有必要说明动作的执行者是谁。

例如:Some new computers were stolen last night.
一些新电脑在昨晚被盗了。(不
知道电脑是谁偷的)
This bridge
was founded in 1981.这座桥竣工于1981年。
(2)强调动作的承受者,而不强调动作的执行者。
例如:The glass was
broken by Mike.玻璃杯是迈克打破的。
This book was
written by him.这本书是他写的。
Your homework must
be finished on time.你们的家庭作业必须及时完成。
四、主动语态变被动语态的方法
(1)把主动语态的宾语变为被动语态的主语。
(2)把谓语变成被动结构(be+过去分词)(根据被动语态句子里的主语的人称
和数,以及原来主动
语态句子中动词的时态来决定be的形式)。
(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。例如:
All
the people laughed at him.
He was laughed
at by all people.
They make the bikes in
the factory.
The bikes are made by them in
the factory.
He cut down a tree.
A
tree was cut down by him.

含有情态动词的主动句变成被动句时,由“情态动词+be+过去分
词”构成,原来带
to的情态动词变成被动语态后“to”仍要保留。
We can
repair this watch in two days.
This watch
can be repaired in two days.
They should
do it at once.
It should be done at once.
六、特殊情况
made the boy work for two
hours yesterday.
The boy was made to work
by him for two hours yesterday.
never
lets me watch TV .
