英语被动语态定义 结构 对应例句
被动语态,即不知道动作执行者或强调动作承受者的一种语态.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.被动语态表示主语是动作的承受者,即行为动作的对象.
英语被动语态的构成通常是：“Be+Passive”.但“Get+Passive”也可以构成被动语态,用这种结构的句子侧重于动作的结果而不是动作本身.如： The man got hurt on his way home. 那个男人在回家的路上受伤了. How did the glass get broken? 杯子怎么破了?
各种时态和句型如下：
①一般时（一般现在,一般过去,一般将来）：am, is, are, was, were, is going to be , will be+done . 例如： Once environmental damage is done, it takes many years for the system to recover. 本句的意思是：“环境一旦遭到破坏,需要多年时间才能恢复过来.”do作为及物动词有“引起,产生”的含义,do damage的意思是“造成破坏”.主语damage是及物动词do的动作对象,谓语应当用被动语态.同样的,还有,I will mend the machine.相当于The machine will be mended （by me）.
②进行时（现在进行、过去进行）：be+being+P.P. 例如：The classroom is being cleaned.
③ 完成时（现在完成、过去完成、将来完成）：have/has been + P.P.：例如The machine will have been repaired by 3 o’clock this afternoon.再如：My homework has been finished.
④ 其他时态 以此类推,可得到结果.
⑤ 情态动词的被动语态：主语 + 情态动词 + be动词 + 动词过去分词,例如Your teeth must be brushed.
⑥ 不定式的被动语态：to be done例：The no-shows have to be considered when deciding the rate of overbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人.）被动语态的用法 1.一般现在时的被动语态构成：is / am / are + 及物动词的过去分词
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
2.一般过去时的被动语态构成：was / were + 及物动词的过去分词

Dinosaur eggs were laid long long ago.
3.现在完成时的被动语态构成：has / have + been + 及物动词的过去分词
This book has been translated into many languages.
Many man-made satellites have been sent up into space by many countries.
4.一般将来时的被动语态构成：will+ be + 及物动词的过去分词
A new hospital will be built in our city.

5.含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词
Young trees must be watered often.
Your mistakes should be corrected right now.
The door may be locked inside.
Your homework can be handed in tomorrow.
6.现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词

7.不定式的被动语态：to + be + 及物动词的过去分词

主动语态改被动语态 把主动语态改为被动语态非常简单,可以遵循以下几个步骤：
1. 先找出谓语动词；
2. 再找出谓语动词后的宾语；
3. 把宾语用作被动语态中的主语；
4. 注意人称、时态和数的变化.
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.

2.有些动词用主动形式表示被动意义.

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 . 感官动词有smell,sound,taste,fell等.使役动词有let,make,have,help,hear,see,watch,notise,look,listen.
例：make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something

The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
His mother gave him a present for his birthday.→ He was given a present by his mother for his birthday.
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 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.

He listens to the radio every day. →The radio is listened to by him every day.
