主动语态和被动语态
1. 英语动词有两种语态,即主动语态和被动语态。
2. 当主语为动作的执行者时,谓语的形式为主动语态。
3. 当主语为动作的承受者时,谓语的形式为被动语态。
例如:
Many people speak English. (主动语态,句子的主语many people是动作speak的执行者。
English is spoken by many people. (被动语态,句子的主语English是动作speak的承受者)
Bell invented the telephone in 1876.(主动语态)
The telephone was invented by Bell in 1876. (被动语态)
3
被动语态的用法
1. 当不知道动作的执行者是谁时。如:
His bike has been stolen. 他的自行车被人偷了。(不知道是谁偷的)
2. 用于动作执行者泛指或者不言而明时。如:
Not a book in the library has been taken away. 图书馆里的书没有一本被拿走。(没人拿书,泛指)
3. 用于可以说出动作执行者是谁但强调的是动作的承受者时。如:
The computer was repaired by my son. 电脑被我儿子修好了。
4. 用于出于委婉、礼貌而避免提及自己或对方时。如:
Enough has been said here on this question. 这个问题已经说得够多的了。(意指不要再说下去了)
4
被动语态的用法
5. 用于文章标题、广告、新闻中(此时常会省略be的被动语态)。如:
Renmin Road blocked. 人民路堵塞了。
6. 当动作的执行者不是人时。如:
Many houses were washed away the storm. 许多房子被暴风雨冲走了。
7. 用于商务书信中书信起草人代表公司时。如:
You letter has been received. 你的来信已收到。
5
不能用于被动语态的动词
1. 不及物动词:字典里词后标有vi.的就是不及物动词.不及物动词后不能直接跟有动作的对象(即宾语).若要跟宾语,必须先在其后添加上某个介词。如:appear、come、go、get、fall、feel、keep、look等
2. 系动词:在英语中系动词的主要功能就是把表语和主语联系在一起,常见的系动词有be、look、turn、feel、get、keep、stay等。
3. 一些及物动词:
1) 部分静态动词(表感觉、情感、相互关系等)
表示拥有或者没有的动词,如:表示拥有的(have, own, possess), hold(容纳), contain(包含), belong to(属于), lack(缺少)等。
表示“适合“含义的:suit, fit, become (适合,与......相称的)
表示”相似、等同“含义的:equal, resemble, look like, mean等。
表示”继续、持续“含义的:last
表示”花费“含义的:cost
6
不能用于被动语态的动词
表示”明白“含义的,如:follow, get, catch, take等。
表示”同意、介意“含义的,如:agree with, mind等。
2)部分短暂性的动词
表示位置移动的动词:leave, arrive at/in, reach, enter, walk into, go into, jump等。这些虽然是及物动词,但是变成被动语态是讲不能的,也不能换成被动语态。比如:
I arrived at home late last night. 我昨天很晚到家。不能说成:
Home was arrived at by me late last night.
7
被动语态的构成
1. 被动语态由“助动词be + 及物动词的过去分词”构成。
2. 助动词be有人称、数的变化。其变化规则与be作为连系动词时完全一样。
3. 下面是以动词ask为例,将一般现在时和一般过去时被动语态的肯定式、否定式及疑问式列表如下:
肯定式 否定式 疑问式
一般现在时 I am asked... He/She is asked... We/You/They are asked... I am not asked... He/She is not asked... We/You/They are not asked... Am I asked...
Is he/she asked...

含有情态动词的被动语态
1. 含有情态动词的被动语态由”情态动词 + be + 及物动词的过去分词“构成。其时态及句型的变化仅由情态动词完成,“be+过去分词”部分不变。
例如:
Teenagers should be allowed to make their decisions.
Your room must be cleaned every day.
The trees may be planted behind the house.
This game can be played in the winter.
2. 含有情态动词的被动语态变为否定句时,应在情态动词后面加not;变为一般疑问句时,应将情态动词移到句首。
Waste paper should not be thrown here. 废纸不应该扔在这里。
Should it be done by Li Ming? 这件事应该是李明干吗?
23
含有情态动词的被动语态
3. 一般疑问句结构:情态动词 + 主语 + be + 动词的过去分词 + 其他成分。注意只提前情态动词,不提前be。
May she be critized by her father 她被她爸爸批评了吗?
4. 含有情态动词的主动句与被动句之间的转换:把主动句中的宾语变为被动句的宾语,主动句的谓语动词变成“情态动词+be+动词的过去分词”的形式。主动句中的主语变成被动句中的宾语(注意不同成分的代词之间的转换)。如果在不要求强调动作的执行者时,by+宾语可以省略。如:
She must clean the room on weekends.
The room must be cleaned (by her) on weekends.
she在主动句中充当主语,但在被动句中充当宾语,改为宾格的她-her
24
将主动语态变被动语态应注意几个特殊情况:
1.含双宾语的主动结构变为被动结构时,有两种方法:
①将间接宾语变为主语,直接宾语保持不变;
②将直接宾语变为主语,间接宾语用介词to或for引导。例如:
① He told us a story.(变被动语态)
→We were told a story(by him).或:A story was told to
us by him.
② Her mother gave her a new pen.(变被动语态)
A new pen was given to her by her mother.或 She was given a new pen by her mother.
2.短语动词的被动语态:在变为被动语态时,要将短语动词视为一个整体,其后的介词或副词不能省去。例如:
This dictionary mustn't be taken away from the library.
“直接宾语,是一个英语语法用语,是指谓语动词的承受者,可由名词、代词、数词、不定式充当。双宾语由直接宾语和间接宾语组成。间接宾语表示谓语动作的方向(对谁做)或动作的目标(为谁做),间接宾语紧接在谓语动词后,但它在句子中不能单独存在,并且能和直接宾语
组成双宾语。”
25
将主动语态变被动语态应注意几个特殊情况
3.含有复合宾语的主动结构变被动结构时,通常将宾语变为被动句的主语,而宾语补足语就成为主语补足语。注意:省略to的不定式作宾补时,不定式符号to必须补上。例如:
Someone saw him swim in Qianling Lake yesterday.(变被动如下)
He was seen to swim in Qianling Lake yesterday.
4.不定式的被动结构:动词不定式的被动语态为“to be +过去分词”。例如:
The radio says a wild animal zoo is to be built in our city.
5.以疑问代词开头的疑问句转换成被动句时要注意词序:应将主动句中的疑问代词改为介词by的宾语,但仍然放在句子开头。例如:
Who has broken the cup?(改为被动语态)
→By whom has the cup been broken?
26
被动语态和过去分词作表语的区别
1)含义不同:被动语态强调动作,重点说明动作由谁完成、怎样完成;而过去分词作表语通常用来描写情景,叙述人或事物的特征及所处的状态。试比较:
The window is broken.窗子破了。(系表结构)
The window is broken by him.窗子被他打破了。(被动语态)
2)用法不同:过去分词作表语时可以被 so,very,too等程度副词修饰,而被动语态则不能用so,very,too修饰,而需用much,very much,so much,too much修饰。试比较:
He was very interested in science.他对科学有极大兴趣。(系表结构)
I was so much surprised at the scene that I didn't know what to do.我被那种场面搞得大吃一惊,不知所措。(被动语态)
27
初中教材中与被动语态相关的句型
1.be covered with被……覆盖
2.be made of由……制作(发生物理变化)
be made from由……制作(发生化学变化)
be made in由(某地)制造
be made by被(某人)制造
3.be used for被用来……
be used as被当作(作为)……来使用
be used to do sth.被用来做某事
4.It is said that...据说……

It is well known that...众所周知……例如:
28
几种特殊的被动语态
1.带不定式的被动语态。
The child is sure to be punished for that. 那个孩子肯定会因为那件事受罚的。
2. 带介词的动词短语的被动语态。
Such a thing has never been heard of. 这件事前所未闻。
3. 带副词的动词短语的被动语态。
The radio has just been turned off. 收音机刚刚被关上。
4. 当sell, wash, clean, run, ride, wear, write等动词若有状语well, easily, badly来修饰时,用主动形式表达被动意义。
The pen writes well. 这枝钢笔写字流畅。
The book sells well. 这本书很畅销
