什么是被动语态

Question

如题所述

Answer 1

被动语态，即不知道动作执行者或强调动作承受者的一种语态。英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。被动语态表示主语是动作的承受者，即行为动作的对象

例如：Many people speak Chinese.
　　谓语：speak的动作是由主语many people来执行的。
　　例如：Chinese is spoken by many people. 中文Chinese是动词speak的承受者。　被例如中文常说：我被他打，这就是一种被动。但有时由于句子结构上的需要也要用被动，例如It is not unusual for workers in that region to be paid more than a month it 在句中作形式主语。而不定式to be paid more than a month是句子的逻辑主语。结合选项全句的意思是：“那个地方的工人一个多月后才得到工资是常有的事”。

　　be+过去分词(简称P.P.)（+by+动作执行者）（过去分词的概念见上段）

　　3当主动语态要被改成被动的时候，我们把原句的宾语提前，作为改句的主语，主语后置，作为宾语。因此有一点要注意，不及物动词由于不加宾语，没有被动形式，但不及物动词如果与某些介词构成介词短语，可以用被动。例如The fire had been put out before the fireman arrived. Put是不及物动词，但put out是及物动词

　　应用到各种时态和句型,如下：
　　① 一般式（一般现在，一般过去，一般将来）：am, is, are, was, were, is going to be , will be+done . ie. Once environmental damage is done, it takes many years for the system to recover. 本句的意思是：“环境一旦遭到破坏，需要多年时间才能恢复过来。”do作为及物动词有“引起，产生”的含义，do damage的意思是“造成破坏”。主语damage是及物动词do的动作对象，谓语应当用被动语态。同样的，还有，I will mend the machine.相当于The machine will be mended （by me）.
　　②进行时（现在进行、过去进行、将来进行）：be+being+P.P. ie.The classroom is being cleaned.
　　③ 完成时（现在完成、过去完成、将来完成）：have/has been + P.P.：例如The machine will have been repaired by 3 o’clock this afternoon.再如：My homework has been finished.
　　④ 其他时态 以此类推，可得到结果。
　　⑤ 情态动词的被动语态：主语 + 情态动词 + be动词 + 动词过去分词，例如Your teeth must be brushed.
　　⑥ 不定式的被动语态：to be done例：The no-shows have to be considered when deciding the rate of overbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人。）
编辑本段主动语态变为被动的几个特殊情况
　　① 有些动词在主动结构中，后面接不带to的不定式，但如果改为被动，则需把省略的to加上，这类动词有 [let, make, have,help]和感官动词[feel,see,hear,watch,look at,listen to]，如：The boss made my grandfather work 10hours a day.改成My grandfather was made to work for 10 hours a day.
　　② 含有宾语从句的主动结构变为被动，通常用it作为被动结构的先行主语，从句放在句子后面/也可采用另一种形式，这类动词有：know, say, believe, find, think, report等
　　③ 不是所有的主动句都可以变换成被动句，更不是所有的被动句都可以自由变换成主动句。虽然语法原则上允许主动和被动句的互相转换，但有的句子转换后会变成不通顺或不地道的英语句子。因此，在某些题目里，这也成为判断应该用主动还是用被动的依据。
　　例：At 5:05 p.m. on Saturday 19th July , there was an accident at the junction of the Main Street and Panda Road when a boy was knocked down off his bicycle by a delivery van. The boy was sent to St. Maria Hospital where he was treated for shock and a broken arm.
　　在这段文章里，a boy was knocked down off his bicycle by a delivery van这句被动句强调出读到文章的人最关心的事故的受害者。The boy was sent to St. Maria Hospital这句话则说明了孩子被送到医院的事实，至于是由谁（某个过路人？或肇事司机？）送的不重要。he was treated for shock and a broken arm这句被动句无须说出treat这个动作的发出者，因为在医院，伤病员自然由医务人员处理，无须罗嗦。这样，这段文章就重点突出，条理清楚了。
　　④ 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，另一个宾语仍然保留在谓语后面。多是把间接宾语变为主语。这样句子自然些。直接宾语变为主语时，间接宾语要变为某个介词的宾语，介词to可以省略。如His father left him this house.改为This house was left (to) him by his father.
　　⑤ 有些动词虽为及物，但宾语并非是动作承受者，不能转换，这些动词有have, hold（容纳）,suit, fit, lack, become（适合）contain, cost, last, mean, suffice（足够）等。
　　⑥ 当直接宾语为反身代词、相互代词或宾语前有指代主语的物主代词时不用被动，如I shook my head.我摇摇头。
　　⑦ 当宾语为同源宾语（与主句指同一人），动名词，动词不定式或一个从句时不用被动。如John enjoyed seeing the fil,.
　　⑧ 在一些固定说法中，有些名词和动词结合的固定说法，不能改We Chinese always keep our word.
　　⑨ 某些从不及物动词转化来的及物动词，直接宾语在表示动作的方式或效果时，这些动词在意思上起状语的作用，没有被动The girl kissed her boyfriend good night=The girl said good night to her boyfriend by kissing him.(这个女孩说了晚安并且亲了他的男朋友）
　　⑩ 表地点\处所\组织\长度\大小\数量\程度\抽象名词的词做宾语时不用被动.
　　⑪ 某些“不及物动词+介词”短语,walk into, listen to, sleep in, agree with, shake hands with, belong to, take part in, keep up with不能用被动。
　　⑫ 某些词用主动表被动：sell, miss, build, grow, look, smell, taste, sound, feel等
编辑本段被动语态的用法
　　1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词
　　Our classroom is cleaned everyday.
　　I am asked to study hard.
　　Knives are used for cutting things.
　　2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词

　　4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词

　　5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词
　　Young trees must be watered often.
　　Your mistakes should be corrected right now.
　　The door may be locked inside.
　　Your homework can be handed in tomorrow.
　　6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词

　　They are planting trees over there. →
　　Trees are being planted over there by them.
　　7. 不定式的被动语态：to + be + 及物动词的过去分词

编辑本段主动语态改被动语态
　　把主动语态改为被动语态非常简单，可以遵循以下几个步骤：
　　1. 先找出谓语动词；
　　2. 再找出谓语动词后的宾语；
　　3. 把宾语用作被动语态中的主语；
　　4. 注意人称、时态和数的变化。
　　例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.
　　2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
　　3. He has written two novels so far.→Two novels have been written by him so far.
　　4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
　　5. Lucy is writing a letter now.→A letter is being written by Lucy now.
　　6. You must lock the door when you leave.→the door must be locked when you leave.

　

　1. 不及物动词无被动语态。
　　What will happen in 100 years.
　　The dinosaurs disappeared about 65 million years ago.
　　2. 有些动词用主动形式表示被动意义。
　　This pen writes well.
　　This new book sells well.
　　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
　　A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
　　The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
　　His mother gave him a present for his birthday.→ He was given a present by his mother for his birthday.
　　4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。
　　He gave me a book.→A book was given to me by him.
　　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。
　　We can't laugh at him. →He can’t be laughed at by us.
　　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.
　　6.宾语补足语的被动语态
　　They call him Bob./He is called Bob.　
　　7.谓语补助语态
　　He is a bed boy。

呵呵，希望可以帮到你，有不懂的还可以问我^^

Answer 2

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。
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)
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
