被动语态
一、语态概述
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。如:Many people speak English. 谓语:speak
的动作是由主语many people来执行的。
被动语态表示主语是动作的承受者,即行为动作的对象。所谓“被动语态”,相
“被……”、“由……”的句式, 当于中文中常说的
如:“他的自行车被偷了。”,再如:English is spoken by many people. 主语English是动词speak的承受者。
判断:看下面的两个例句,你来判断哪个是主动哪个是被动? He opened the door.他开了门。 (____________) The door was opened.门被开了。 (____________)
二、被动语态的构成: be动词+Vp.p
被动特点强调宾,用be加上过去分。行为对象作主语,逻辑主语by来引。 1. English is ___________(speak)in Canada. 2. The blouse is ___________(make)of silk.
3. English is ___________(speak)by many people.
谁做的动作不知道,说出谁做的没必要。动作承受者需强调,用被动语态莫忘了。 1. Some stamps were ___________(steal)last week.
2. The PRC was ___________(found)on October 1, 1949. 3. Football is ___________(play)in most middle schools.
被动语态须留意,P.P前面助动be. be + P.P
am(is,are)现在时,am(is,are)+P.P was和were表过去。was(were)+P.P
完成have(has)been。have(has)been+P.P
将来,情态,be原形。will(can,may,must)be+P.P
进行时态两个be,前表时态后加ing。am(is,are)+being+P.P
被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。凡是汉语中带“被”的句子,都能转换成英语的被动语态。 三.几种常用时态的被动语态——
1.一般现在时: am/is/are+过去分词
肯定句:Bikes are ___________(sell)in that shop. 否定句:Bikes are not sold in that shop.
疑问句:Are bikes sold in that shop? Yes, they are. / No, they aren't.
2.一般过去时: was/were+过去分词
肯定句:He was ___________(save)in 1999. 否定句:He was not saved in 1999.
疑问句:Was he saved in 1999? Yes, he was. / No,he wasn't.
3.一般将来时: shall/will/be going to + be+过去分词
肯定句:An English class will be ___________(give)by Jack tomorrow. 否定句:An English class will not be given by Jack tomorrow. 疑问句:Will an English class be given by Jack tomorrow?
4.现在进行时:am/is/are + being+过去分词
肯定句:A car is being ___________(drive)now. 否定句:A car is not being driven now.
疑问句:Is a car being driven now? Yes, it is. / No, it isn't.
5.现在完成时:have / has+ been+过去分词
肯定句:A road has been ___________(build)by the government. 否定句:A road hasn't been built by the government.
疑问句:Has a road been built by the government? Yes, it has. / No, it hasn't.
6.情态动词:情态动词+be + P.P
1)This clock can be ___________(repair)here.
2)The trees may be ___________(plant)at other times of the year. 3)The composition must be ___________(hand)in after class. 4)The young trees should be ___________(plant)in spring.
四、被动语态的用法
(1)不知道或没有必要说明动作的执行者是谁。例如: Some new computers were ___________(steal)last night. 一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)
This book was ___________(publish)in 1981. 这本书出版于1981年。
(2)强调动作的承受者,而不强调动作的执行者。例如:
The window was ___________(break)by Mike. 窗户是迈克打破的。 This book was ___________(write)by him. 这本书是他写的。
Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。
五、主动语态变被动语态的方法
(1)把主动语态的宾语变为被动语态的主语。 (2)把谓语变成被动结构(be+过去分词)
(根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式)。 (3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。例如: 1.All the people ___________(laugh)at him.
→ He was ___________(laugh)at by all people. 2.They ___________(make)the bikes in the factory.
→ The bikes are ___________(make)by them in the factory.
六、补充
一些宾补动词如make, see, hear等在主动语态中可以接动词原形(实为省略to的动词不定式)作为宾语补足语的动词在变被动语态是一定要注意恢复to。如:
He made me stand outside. → I was made to stand outside(by him). I saw him play football. → He was seen to play football(by him).
