特殊用法

1.不及物动词无被动语态。 如：happen, break down, come out......

2.有些动词用主动形式表示被动意义。 如： write, sell, ride.....

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”。

例：make somebody do something→somebody+ be +made to do something

see somebody do something→somebody +be +seen to do something

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.

The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.

被动语态通常为十种时态的被动形式,被动语态由“be+过去分词”构成，be随时态的变化而变化。以do为例，各种时态的被动语态形式为：

被动语态的特殊结构形式

1 带情态动词的被动结构。其形式为：情态动词+be+过去分词。

The baby should be taken good care of by the baby-sitter.

2 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。

His mother gave him a present for his birthday.可改为He was given a present by his mother for his birthday.

3 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。

Someone caught the boy smoking a cigarette.可改为The boy was caught smoking a cigarette.

4 在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。

Someone saw a stranger walk into the building.可改为A stranger was seen to walk into the building.

5 有些相当于及物动词的动词词组，如“动词+介词”，“动词+副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。

The meeting is to be put off till Friday.

非谓语动词的被动语态

v.+ing形式及不定式to do也有被动语态(一般时态和完成时态)。

I don't like being laughed at in the public.

如何使用被动语态

学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。

1 讲话者不知道动作的执行者或不必说出动作的执行者(这时可省by短语)。

My bike was stolen last night.

2 借助被动的动作突出动作的执行者。

I was given ten minutes to decide whether I should accept the offer.

3 为了更好地安排句子。

The well-known person got on the bus and was immediately recognized by people.（一个主语就够了）

▲高考英语语法必考知识点：被动语态的用法

It is said that+从句及其他类似句型

一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It+be+过去分词+that从句”或“主语+be+过去分词+to do sth.”。有：

It is said that…据说……

It is reported that…据报道……

It is believed that…大家相信……

It is hoped that…大家希望……

It is well-known that…众所周知……

It is thought that…大家认为……

It is suggested that…据建议……

It is said that the boy has passed the national exam.（=The boy is said to have passed the national exam.）

四、谓语动词的主动形式表示被动意义

1 英语中有很多动词如break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表达被动意义,主语通常是物。

This kind of cloth washes well.

注意：主动语态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。试比较：The door won't lock．（指门本身有毛病）

The door won't be locked．（指不会有人来锁门,指“门没有锁”是人的原因）

2 表示“发生、进行”的不及物动词和短语，如：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。

How do the newspapers come out这些报纸是如何引出来的呢

3 系动词没有被动形式,但有些表示感受、感官的连系动词feel, sound, taste, look, feel等在主系表结构中常以主动形式表示被动意义。

Your reason sounds reasonable.

非谓语动词的主动形式表被动意义

在某些句型中可用动名词和不定式的主动形式表被动意义

1 在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。

The house needs repairing（to be repaired）．这房子需要修理。

2 形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。

The picture-book is well worth reading．（=The picture-book is very worthy to be read．）

3 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系,不定式的主动形式表示被动含义。

I have a lot of things to do this afternoon．(to do与things是动宾关系，与I是主谓关系。)试比较：

I’ll go to the post office. Do you have a letter to be posted (此处用不定式的被动语态作定语表明you不是post动作的执行者。)

4 在某些“形容词+不定式”做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。例This problem is difficult to work out .（可看作to work out省略了for me）.

5 在too… to…结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。

This book is too expensive (for me) to buy.

6 在there be…句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。例There is no time to lose（to be lost）．（用to lose可看成for us to lose；用to be lost，谁lost time不明确。）

7 在be to do结构中的一些不定式通常应用主动表主动,被动表被动。然而,由于古英语的影响,下列动词rent, blame, let等仍用不定式的主动形式表示被动意义。

Who is to blame for starting the fire

▲高考英语语法必考知识点：被动语态的用法

介词in，on等+名词构成介词短语表被动意义

表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。

1 “under +名词”结构，表示“某事在进行中”。常见的有：under control（受控制）, under treatment（在治疗中）, under repair（在修理中）, under discussion（在讨论中）, under construction（在施工中）。

The building is under construction( is being constructed).

2 “beyond+名词”结构，“出乎……胜过……、范围、限度”。常见的有：beyond belief (令人难以置信)，beyond one’s reach（鞭长莫及），beyond one’s control（无法控制），beyond our hope．我们的成功始料不及。

The rumour is beyond belief（=can’t be believed）．

3 “above+名词”结构,表示“(品质、行为、能力等)超过……、高于……”。

His honest character is above all praise．=His honest character cannot be praised enough．

4 “for+名词”结构，表示“适于……、为着……”。如：for sale(出售), for rent（出租）等。

That house is for sale. (= That house is to be sold).

5 “in+名词”结构，表示“在……过程中或范围内”常见的有：in print（在印刷中），in sight(在视野范围内)，等。
