被动语态由“助动词be +及物动词的过去分词”构成。助动词be 有人称、数和时态的变化,其变化规则与be作为连系动词时完全一样。被动语态的一定式、否定式及疑问式列表如下:
肯 定 句: 主语+ be+ 过去分词 +(by…) eg. He is often asked to do this work .
否 定 句:主语+ be not +过去分词 +(by…) eg. I am not invited to the party .
一般疑问句:Be + 主语+过去分词+ (by…)? eg. Are your clothes washed by yourself?
特殊疑问句:疑问词+ be+主语 +过去分词+ (by…)? eg. What is this sweater made of?
现以动词give为例,其被动语态的各种时态如下:
式 时 |
一 般 |
进 行 |
完 成 |
目前 | Am / is /are + given | Am/is/are +being + given | Have / has +been +given |
过去 | Was / were + given | Was / were + being + given | Had +been + given |
以后 | Shall/ will + given | Shall / will +be + given | Should /would + be + given |
含情态词的 | Can / may /must +be +given |

1、当大家不了解哪个是动作的实行者,或者没必要指出哪个是动作的实行者,或者指需要强调动作的承受者时,要用被动语态。比如:
The cotton is grown in that farm.。
2、大家关心动作的承受者但也关心动作的实行者,要用被动语态。比如:
Nahan was written by Lu Xun.。
3、表示科学性及客观性,在新闻报道和科技文章中用得较多。比如:
Many of the stars cannot be seen because they are too far away.It was reported that the scientists were searching for new ways to solve the problems.容易见到的句型结构如下:It is (was)agreed(believed/decided/hoped/thought......)that......大伙赞同(相信、决定、期望、觉得)......
It is(was) well known that......大家都知道
It is(was )taken for granted that......被视为当然
It must be remembered that......务必记住......
It mustn’t be forgotten that......千万不要忘记......
It is(was) said(reported,heard,told,suggested)that......据了解(报道、听说、告知、建议......)

英语中有主动和被动之分,并都以特定的形式出现。然而并不是所有些主动句式都表示主动意义,有的句子形式是主动的,而意义却是被动的。就其在英语中的具体运用,从以下几个方面加以总结。
1、一些表示感觉、感官的连系动词如:feel,sound,taste,look等后面接形容词作表语,形式上是主动的, 意思上表示被动。比如:
The mixture tasted terrible.。
She sound nice. She has a beautiful voice.Your father looks very angry. What's the matter? 2、有少数及物动词(do, owe欠 ,cook, print, build)等,常用进行时态表示被动意思。比如:
The meat is cooking. 。
The book is printing.。
3、一些表达事物行为、方法的动词如:wash, sell, write, say, open等,习惯以主动形式表示被动的意思。由于如此用更简洁,更符合英美人的习惯,特别在口语中。比如:
The shop was quite new, for it had opened only the week before.This kind of cloth washes very well。
The door opened and in came Mr. White.。
The book sells well.
4、表示“发生,进行”之类不及物动词如:happen,last,take place, break out,go on, go by, move on等,以主动式表示被动含义。比如:
You'd better wait and see what happens to him.Over 500 people were working in the building when the fire broke out on the 11th floor.
Will the weather last long?
But many months went by and no one visited the island.
5、有的“系动词+分词”的结构,意思上也接近被动结构。比如:
He got wounded in a battle.他在一次战斗中负伤。
Many countries became liberated in the following months.下面的数月中,很多国家获得解放。
6、be + 副词或介词短语,如be on, be on show, be on sale, be in(out of) sight, be under discussion等,这种副词或介词短语总是具备动词含义,等于被动语态表达的意义。比如:
Summer wear is on sale.(=Summer wear is being sold.)
The film had been on for five minutes when I got to the cinema.(=The film had been show when I got to the cinema.)The two canoes were almost out of sight.。
7、不定式作后置定语的结构。当作定语用的不定式除去被修饰的词有动宾关系外,还与句子的主语或宾语有逻辑上的主谓关系,不定式须用主动形式表示被动含义。比如:
Is there anything to say?
We have a lot of things to do
注意:若不定式与句子主语或宾语没有逻辑上的主谓关系,只与所修饰的词有动宾关系时,即只有动作的承受者,没动作的实行者时,不定式应用被动式。比如:
He has something to be told to you.
Have you anything to be taken to him
8、be+形容词+不定式结构。此结构的不定式与主语之间有逻辑上的动宾关系,因而不定式须用及物动词或相当与及物动词的短语动词。因而此结构的形容词大部分表示说话人对不定式动作的怎么看态度或感受等。如difficult, easy, hard, interesting, pleasant, fit,等或表示主语人或物所具备的特点,如 :nice,light,strong,beautiful,heavy等。形式上是主动的,意思上却是被动的。比如:
This text is very difficult to understand. The water is not fit to drink.
The man is very easy to get along with. The room is comfortable to live in.
9、当表示“需要”含义的动词如:need, require, want等作谓语,其主语为物时,这种动词后面的动名词要用主动形式表示被动意思。比如:
The house needs cleaning.
My hair requires cutting.
10、worth用作形容词时,作表语,后面一般接动名词的主动形式表示被动的意思。比如:
This book is well worth reading.
11、be+形容词结构。这种形容词如:invisible, forgettable,comfortable等具备动词含义的特征。因而常以主动形式表示被动含义。比如:
Names and addresses are forgettable.
12、there be句型中修饰主语的不定式,可用主动式表示被动含义。比如:
There is nothing to do . There are questions to solve.
13、be +不定式结构。这种结构如be to blame, to be let, be to seek等,具备的特征是作表语的不定式与句子的主语有逻辑上的动宾关系,因而以主动形式表示被动含义。比如:
The house is to let.此房屋要出租。
I felt I was to blame.我感觉我应该受罚。
A better way is to seek.还要找一种更好的方法。
14、某些固定词组和句型,用主动形式却表示被动意义。如add up , take place; catch on , turn out , blow open, consist of, come out sth., remains to do sth. be to blame.等。比如:
His whole schooling added up to no more than a year.
Sorry, I can't go with you. Much work remains to do.
__________
1) __________ __________ __________ __________
主语 谓语 宾语
→ __________ __________ to her dinner party.
主语 谓语 宾语
2) __________ __________ __________.
主语 谓语 宾语
→ __________ __________ __________.
主语 谓语 宾语
1.把主动语态的宾语变成被动语态的主语。
2.把主动语态的谓语变成被动语态的be + 过去分词,时态要与原句维持一致。
3.把主动语态的主语变为介词by 的宾语,放在被动语态里谓语动词之后,by 短语可以省略。假如原句主语是地址名词,在被动语态中用in + 地址名词作状语。
__________
1. 把主动语态变为被动语态时,其谓语动词的时态要与原句时态维持一致,其谓语动词的数要与新主语维持一致。
We have bought a new computer. →A new computer has been bought.
2. 含有双宾语的主动句变被动句时,可分别将它中的一个宾语变为主语,另一个不动,一般变间接宾语为主语时比较多。
My uncle gave me a present on my birthday. →I was given a present on my birthday.
假如把直接宾语改为主语,则在间接宾语前加适合的介词,如上句还可以说:
A present was given to me yesterday.
注意:一般在下列动词后,常在间接宾语前用介词 to,如:bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。
The cup with mixture was showed to the class. My bike was lent to her.
