被动语态部分

百楼中学 张硕

英语的两大语态：主动语态和被动语态

A.主动语态中主语是谓语动词的发出者。宾语是谓语动词的对象。

B.被动语态中主语是谓语动词的承受者(动作的对象)。

(把主动语态改为被动语态也就是把主动句中的宾语改为被动句的主语，这是最关键的着眼点，同时谓语动词作相应的变化。)

被动语态的谓语构成:　助动词be＋动词过去分词

(根据句子的主语和时态，助动词be有am, is, are, was, were,

been几个形式变化。)

什么时候要用被动语态呢？

在下列三种情况之一要用被动语态：

①不知道动作的执行者是谁，用被动语态。

②没有必要指出谁是动作的执行者，用被动语态。

③需要强调动作的承受者时，用被动语态。

主动句中谓语动词的发出者由by引出，作为by的宾语，也可以省略。

请看以下主动语态和被动语态结构的转换：

主动语态:主语＋谓语＋宾语

被动语态:

例： We clean our classroom every day. （主动）

[注意]①把主动语态改为被动语态时，句子的时态不能变。如上

例，所给的主动句子是一般现在时，改为被动语态时，也

要用一般现在时。

　　　②如果主动句中的主语是人称代词，改为被动句时作介词

by的宾语，要用宾格。如上例中的主语we改为us。

（被动）

把下列主动句改为被动句

①Lily writes many letters every day. (主动)

②They visited this farm last year.（主动）

③We have learned 3000 English words so far.（主动）

→

Many letters

are written

by Lily

every day.

→

This farm

was visited

by them

last year.

→

3000 English words

have been learned

by us

so far.

在被动语态中要注意的问题

　　在上面我们已经初步了解了被动语态的构成和主动变被动的方法。下面

我们接着学习在被动语态中要注意的问题。

　　①一些使役动词(let, have, make等)或感观动词(see, hear, watch,

notice等)在主动语态中后面接的动词不定式不带to，但改为被动语态时，要

补上to。如：

The boss makes the workers work 18 hours a day.

The workers are made to work 18 hours a day by the boss.

I saw him enter the house.

He was seen to enter the house by me.

The teacher let them leave the classroom after class.

They were let to leave the classroom by the teacher after class.

We hear her sing in the room every day.

She is heard to sing in the room every day.

[注意]当使用see/hear/watch sb doing sth时，变为被动语态时，

doing保持不变。如：

　　 I saw him going into the shop.(主动)

He was seen going into the shop.(被动)

go

Homework

把下列句子改为被动语态

1. We plant many trees every year.

Many trees are planted by us every year.

2. His mother made him wash his own clothes at the age of 10.

He was made to wash his own clothes by his mother at the age of 10.

②含有短语的被动语态结构。

　　一般来说，只有及物动词才有被动语态，因为只有及物动词才有承受者。

但许多不及物动词加上副词或介词构成动词短语也相当于及物动词的用法，可以

带宾语，因而也有被动语态。动词短语主要有三种：

A 及物动词+副词 如：

turn off 、 set up 、 carry out 、 put off 、take away 、 turn on 、 hand in 、 move away 、 pass on 、 write down 、put away 、 put on 、 take down 、send away 、 try on 、 put down 、sell out 、 hold on 、 try out 、 send up 、 take off 、 wear out 、wake up 、take out 、dress up 、 give back 、 work out 、 get back 、 find out 、pick up 、give up 、 pull up 、 put up 等

B 不及物动词+介词 如：

look after talk about play with等

?

C.“动词+名词+介词” 构成的短语。如：

take care of、 pay attention to、make use of等动词短语是不可

分割的整体，在变被动语态时，不可丢掉构成动词短语的副词或介词。

请看下面的例子：

①They set up the factory in 2000.

The factory was set up in 2000.

②Our school will put off the School Sports meeting until December.

The School Sports meeting will be put off until December.

③People have talked about the accident .

The accident has been talked about.

④You should pay more attention to your study this year.

Your study should be paid more attention to this year.

带有介词或副词的动词短语，在改为被动语态时，不能把介词或副词

拆开。

③带有双宾语的被动结构在句中的使用。

有些动词可以带两个宾语，即指人的间宾和指物的直宾。可以将其中一

个宾语提到前面做主语，另一个留在后面。

①Her parents bought her a new computer yesterday.

She was bought a new computer yesterday.

A new computer was bought for her yesterday.

②They have given me some good advice.

I have been given some good advice.

Some good advice has been given to me.

③She will write a long letter to David Smith.

A long letter will be written to David Smith.

David Smith will be written a long letter.

buy sth for sb

give sth to sb

带双宾语的动词主要有以下几个：

give, buy, sell, take, bring, make, hand, pass, keep, send等带双宾语

的动词，改为被动语态，当用直接宾语作主语时，要根据动词的习

惯配搭、要在间接宾语前补上介词to或for.

它们的句型主要有以下几个：

①give sth to sb=give sb sth ②buy sth for sb=buy sb sth

③sell sth to sb=sell sb sth ④take sth to sb=take sb sth

⑤bring sth to sb=bring sb sth ⑥make sth for sb=make sb sth

⑦hand sth to sb=hand sb sth ⑧pass sth to sb=pass sb sth

⑨keep sth for sb=keep sb sth ⑩send sth to sb=send sb sth

例：

①He passed me some paper.(主动)

Some paper was passed to me by him.（被动）

②You must keep some fruit for him.(主动)

Some fruit must be kept for him.（被动）

三、一些特殊的被动结构

（1）某些系动词，如feel. smell.

taste. sound等加上形容词，

可用主动语态表被动意义。

e.g.:The food tastes delicious.

The music sounds very

familiar to me.

（2）动词need. require. want.

be worth. deserve后加v.-ing

的主动结构常表示被动含义

e.g.: My watch can’t work, it

needs repairing.

This film is really worth

seeing.

need, demand, want(需要）, require, be worth等后用动名词表被动。

The desk needs repairing.

The novel is worth seeing.

注意：need后可接动名词表被动，又可接动词不定式的被动形式。但若有附加成分有用动词不定式的被动形式。比较：

The desk needs repairing.

The desk needs to be repaired this afternoon.

4) 注意动名词的被动形式，（being done)

Nobody likes being laughed of. 没人喜欢被嘲笑。

语态的主语改为被动语态的介词by的宾语。

　　②套－－－根据原句的时态套用相应时态。

　　③注意－－注意人称的变化而引起的主谓一致问题。

例：①Many people speak English.
