英语被动语态总结

一、被动语态的构成形式

1. 被动语态的基本时态变化

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:

1) am/is/are +done (过去分词) 一般现在时

例:Visitors are requested not to touch the exhibits.

2) has /have been done 现在完成时

例:All the preparations for the task have been completed, and we're ready tostart.

3) am/is /are being done 现在进行时

例:A new cinema is being built here.

4) was/were done 一般过去时

例:I was given ten minutes to decide whether I should reject the offer.

5) had been done 过去完成时

例:By the end of last year, another new gymnasium had been completed in Beijing.

6) was/were being done 过去进行时

例:A meeting was being held when I was there.

7) shall/will be done/ be going to be done/ be about to be done/ be to be to done一般将来时

例:Hundreds of jobs will be lost if the factory closes.

8) should/would be done; was/ were going to be done; was/ were about to be done; was/ were to be to done一般将来时

例:The news would be sent to the soldier's mother as soon as it arrived.

9) shall/will have been done 将来完成时(少用)

例:The project will have been completed before July.

10) should/would have been done 过去将来完成时(少用)

例:He told me that his new clothes would have been made very soon.

2. 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。 例: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. 例: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。

例: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,但为为被动结构时,要加to。

例: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。

例:The meeting is to be put off till Friday.

3. 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) 。 例:I don't like being laughed at in the public.

二、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。

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

三、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。

例: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。

例: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, book, feel等在主系表结构中常以主动形式表示被动意义。

例:Your reason sounds reasonable.

四、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。

例: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。

例: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。

例: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。

例: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。 例:Who is to blame for starting the fire?

五、介词in, on, under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)。

例: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。

例:The rumor 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……”。 例: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。

例: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。

例:The book is not yet in print.(=is not yet printed)

6.“on+名词”结构, 表示“在从事…… 中”。常见的有:on sale(出售),on show(展出), on trial(受审)。

例:Today some treasures are on show in the museum (= are being showed).

7.“out of+名词”结构 ; 表示 “超出…… 之外“,常见的有:out of control (控

制不了),out of sight (超出视线之外),out of one’s reach(够不着), out of fashion(不流行)等。

例:The plane was out of control (can’t be controlled). 。

8.“within+名词”结构,“在……内、不超过……”。

例:He took two days off within the teacher's permission.

六、被动语态与系表结构的区别

当“be+过去分词”作被动语态时表示主语承受的动作;作系表结构时表示主语的特点或所处的状态时,be后面的过去分词是表语,相当于形容词。其区分办法如下:

1.如果强调动作或句中有介词by引导出动作的执行者,该句一般为被动语态,否则为系表结构。

例:The glass is broken. (系表结构)

The glass was broken by the boy. (被动语态)

2.如果句中有地点、频率或时间状语时,一般为被动语态。

例:The door is locked. (系表结构)

The door has already/just been locked.(被动语态)

3.被动语态除用于一般时态和完成时态外,还可以用于其他各种时态,而系表结构中的系动词be只有一般时态和完成时态。

例:The machine is being repaired.

七、被动语态与高考试题赏析

1.高考对谓语动词语态的考查例析

1). In some parts of the world, tea ___ with milk and sugar. (NMET1993)

A. is serving B. is served C. Serves D. served

解析:B 因为serve是及物动词,其动作承受者tea作主语,表示经常发生的情况,故用一般现在时的被动语态。

2). This is Ted’s phone. We miss him a lot. He ___ trying to save a child in the earthquake.(NMET20xx)

A. killed B. is killed C. was killed D. was killing
