初三英语被动语态小结(Be + done)及练习
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。
如:Many people speak English.
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:English is
spoken
by many people.主语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teach为例说明被动语态在各种时态中的构成。
一般现在时:amisare+taught
一般过去时:waswere+taught
一般将来时:willshall
be+taught
现在完成时:havehas been+taught
情态动词:shouldmustcan…+be+taught
如:
Our
classroom is cleaned every day, but it wasn't
cleaned yesterday. It will be cleaned
by
Group1 tomorrow.
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。
如:
Some new
computers were stolen last night.
This book
was published in 1981.
(2)强调动作的承受者,而不强调动作的执行者。
如:The window was
broken by Mike.
This book was written by
him.
Eight hours per day for sleep must be
guaranteed.
注意:句子的主语是谓语动词的动作的承受者或者主语是动作的对象,因此
只有
及物动词才有被动语态。
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。主动语
态变为被动
语态时,其谓语动词的时态要与原句时态保持一致,其谓语动词的数
要与新主语保持一致。
如:
All the people laughed at him.
改为:He was laughed at by all people.
They
make the bikes in the factory.
改为:The bikes
are made by them in the factory.
五、特殊情况
1.宾语的复合结构:这种情形如果要把主动语态变为被动语态,需把复合结构的
逻辑主语变为
被动语态的主语,此时,原来的宾补变成了主语补足语。(如果原
句是由省“to”的不定式作宾补,变
成被语态时应把省掉的“to”加上)
如:
He made the boy
work for two hours yesterday.
改为:The boy was
made to work by him for two hours yesterday.
Mother never lets me watch TV .
改为: I am
never let to watch TV by mother.
2.双宾语形式
:此时要变被动语态,一般是把人(间接宾语)变为主语;如果非
得把直接宾语变为被动语态的主语,则
应加上介词“for”或“to”。
如:
Jack gave Peter a
Christmas present just now.
改为:(1)A
Christmas present was given to Peter by Jack just
now.
(2)Peter was given a Christmas
present by Jack just now.
3、短语动词的完整性:
如:
We should take good care of the old and
the children.
改为:The old and the children
should be taken good care of.
4、.“get+过去分词”结构也可以表被动。
如:get burnt(着火)、get
killed(被杀)、get hurt(受伤)、get lost(迷路)
get
dressed(穿衣服)、get married(结婚)等。
The boy got
hurt on his way to school. 这个男孩在上学的路上受伤了。
