为什么被动语态有时不用be?
被动语态表示主语是动作的承受者,是动词的一种特殊形式。被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只型羡改变be的形式,过去分词部分不变。疑问式和否定式的变化也如此。被动语态的be在一般情况下都是不可以省略的。但是在前置定语修饰的时候或后置的定语从句中是雀租烂可以省略的。
1被动语态不用be的情况
一、被动语态不用be的情况
1.前置定语修饰的时候
The broken glass.破碎的杯子。
2.后置的定语从句中省略be动词
The man() given a praise is my uncle.被表扬的那个男人是我的叔叔。
省略的部分是“Which is be”。
二、被动语态
1.构成
(1)助动词be+及物动词的过去分词
(2)情态动词+be+及物动词的过去分词
2.特殊用法
(1)不及物动词无被动语态。如:happen, break down, come out......
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
(2)有些动词用主动形式表示被动意义。如: write, sell, ride.....
This pen writes well.
This new book sells well.
(3)感官动词或使役动词使用省略to的动词不定式,主动语态中不带“to”,但变为被动语态时,须加上“to”。
make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
(4)如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。
He gave me a book.→A book was given to me by him.
He showed me a ticket.→A ticket was shown to me by him.
My father bought me a new bike. →A new bike was bought for me by my father.
(5)一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。
We can’t laugh at him. →He can’顷漏t be laughed at by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
被动语态是指谓语动词的被动形式,一定要有be+过去分词,比如The Window was broken.
但是表示被动的还有过去分词或过去分词短语,但它们是非谓语动词,不会做谓语,通常做定语,单独的放名词前面,短语放名词后面。比如developed countries发达国家。a boy named Billy一个叫比利的男孩。
语言是发展变化的。
最初一定是“be+过去分词”才能构成友敬被动语态。
后来一些连系动词如get,become也能加过去分野告耐词构成被动语态。如:
He got hurt yesterday.昨天他受伤了。
He became interested in art at last.最终他对艺术感兴趣了。
现在,“be/get/bcome+过去分词”,除了表示被动颂春含义,有时候也理解为系表结构,也就是说,有些动词的过去分词也可以作形容词用,如interested,worried,broken等等。
被动语态是消悔指谓语动词的被动形式,一定要有be+过去分词,比如The Window was broken.
但是表示被动的还有过去分词或圆桥握过去分词短语,但它们是非谓语动词,不会做谓语,通常做定语,单独的放名词前橘庆面,短语放名词后面。比如developed countries发达国家。a boy named Billy一个叫比利的男孩。
be +动词的过去分词。例如
The homework was finished .
作业已经被完成老陵枝。
The power is cut off.
电源被切断了。
我被骗了。I was cheated.
被骗后,我感觉很难受。After
首先,我们要知道的是,有些动词,本身是没有被动形式的,比如。
嘿嘿,为什么,比如之后,我没写呢。因为我也没有一个系统兄颤的有关这方面的知识体系,然后我就去网上查,后来,羡塌败我转念一想,既然我可以查到,你也可以查到,通过自己整理,形成一个自己的东西。如果你实在很“懒羊羊”,那就继续往下看吧。我随机在网上摘录的如下——
end(结束);happen(发生);spread(撒下);衫则last(持续);fail(失败);appear(出现);disappear(消失);remain(提醒);sit(坐下); die(死亡);lie(说谎);stand(起立);lose heart(内心迷失);take place(发生;出现);come true(实现);break out(爆发);keep silence(保持沉默); fall asleep(睡觉)等等。
