被动语态自述
【知识梳理】
一、概念
英语中的语态是表示主语和谓语之间的关系,主要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:
Millie often sings this English song.
谓语:sing的动作是由主语Millie发出的,即Millie是sing this
English song这个动
作的执行者。
◆被动语态表示主语是动作的承受者,即行为动作的对象。如:
This English
song is sung by Millie.
主语this English
song是动词sing发出的,即sing这个动作的承受者。
二、构成
被动语态由“b
e+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。需要注意的是:其中
的动词必须是及物动词。
现以sing为例说明被动语态在各种时态中的构成。
一般现在时的被动语态:am/is/are+sung
一般过去时的被动语态:was/were+sung
一般将来时的被动语态:will/shall be+sung
现在进行时的被动语态:am/is/are being+sung
过去进行时的被动语态:have/has been+sung
现在完成时的被动语态:have/has been+sung
过去完成时的被动语态:had been + sung
三、变换
1、把主动语态的宾语变为被动语态的主语。如果是人称代词的宾格须变成主格;
2、把谓语变成被动结构:be+过去分词。需要注意的是:要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,变成被动语态后的句子
的时态须与原
来主动语态的句子时态保持一致;
3、把主动语态中的主语放在介词by之后作宾语。如果是人称代词主格须改为宾格。
4、其余部分照写。如:
I watched a football match on
TV last night.
→A football match on
TV was watched by me last night.
【拓展延伸】
1、在含有使役动词(make, let, have)、感官动词(hear, see,
watch, find, feel等)
以及help的句子中,在主动语态中这些词后接动词原形(
即省to的动词不定式),在变成
被动语态时,须将to补上。如:
I saw him
play football on the playground just now.
→He
was seen to play football on the playground by me.
2、teach, give, show, pass, buy, tell等后常接两个宾语,即
双宾语:直接宾语(表物
的)和间接宾语(表人的)。变成被动语态时,可以选取其中任一个做主语。但
需要注意的
是:如果选取直接宾语做主语时,那么间接宾语钱须加相应的介词for或to。如:
Helen showed me a photo.
→I
was shown a photo by Helen.
→A photo was shown
to me by Helen.
3、由“不及物动词+ 介词副词+
宾语”的句子变成被动语态时,介词或副词不能丢掉。如:
She took good care
of her grandmother.
→Her grandmother was taken
good care of by her.
四、用法
1、不知道或没有必要说明动作的执行者是谁时。如:
The red car was
made in Yancheng, Jiangsu.
这辆红色小汽车是江苏盐城产的。(不知道这辆小汽车是谁制造的)
The Sutong
Highway Bridge was founded in 2007.
这座桥竣工于2007年。(不知道苏通大桥是谁建造的)
2、需要突出或强调动作的承受者
,而不强调动作的执行者,这时常由by短语引出动作的执
行者。 例如:
The
window was broken by Jack last night.
窗子杰克昨晚打破的。(强调打破窗子这一动作的执行者是Jack)
3、出于礼貌或交际需要而不愿说出动作的执行者。如:
You are wanted
on the phone, Miss Fang.
方老师,你的电话。
【友情提醒】
1、不及物动词,连系动词及短语不能用于被动语态,常见的动happen, appear,
stay, break
out, take place, belong to , come
true ,come out等。如:
The famous writer’s new
book will come out soon.
那位著名作家的新书马上就要出版了。
2、主语是感觉的对象,动词表示给人以什么样的感觉,如smell(闻起来),taste(尝起来),<
br>feel(摸起来),look(看起来),sound(听起来)通常用作连系动词,后面用形容词作表
语,
不用于被动语态。如:
The silk feels soft.
丝绸摸上去软绵绵的。
3、不定式在形容词后做状语时构成be+ adj +to
do结构时,不定式不用于被动语态。常见
的形容词有easy ,hard
,difficult等。如:
The question is easy to answer.
这个问题容易回答。
4、不定式做后置定语时,如果不定式的逻辑主语能在句中找到,不定式
用主动形式表示被
动意义。反之,不能找到不定式的逻辑主语,不定式用被动语态。如:
I
have a lot of homework to do this evening.
今晚我又许多家庭作业要做。
5、在require, need
等后用动名词主动形式表示被动意义,也可以用不定式被动语态。如:
My old bike needs repairing =My old bike needs
to be required。
我的旧自行车需要修一下。
