被动语态语态是动词的一种形式,用以说明主语与谓语动词之间的关系。
英语的语态共有两种: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。
被动语态是动词的一种特殊形式,一般说来,只有需要动作对象的及物动词才有被动语态。
汉语往往用"被"、"受"、"给"等被动词来表示被动意义一、语态结构比较语态时态主动语态被动语态一般现在时①am\is\are ②do/does(V.\V.s) am\is\are+done(V. p.p)一般将来时will\be going to\be(about)to+do(V.) will+be+done(V. p.p)一般过去时①was\were ②did(V.-ed) was\were+done(V. p.p)现在进行时am\is\are+doing(V.-ing) am\is\are+being+done(V. p.p)过去进行时was\were+doing(V.-ing) was\were+being+done(V.p.p)现在完成时have\has+done(V. p.p.) have\has+been+done(V. p.p)过去完成时had+done(V. p.p.) had+been+done(V. p.p.)情态动词情态动词+V. 情态动词+be+done(V. p.p.)过去将来时would/should +V. would/should be +done(V. p.p.)二、变被动句步骤1、把原主动句中的宾语变为被动句的主语2、把动词变为被动形式即be +过去分词,并注意其人称和数随主语的变化,而动词的时态则保持不变。
3、原主动句的主语如需要则放在by后面以它的宾格形式出现(注代词的宾格),如不需要则可省略。
4、其它的成分(定语、状语)不变。

初中英语被动语态专项讲解一、语态概述语态是动词的一种形式,表示句子之中主语和谓语动词的关系。
英语有两种语态:主动语态和被动语态主动语态表示主语是动作的发出者(或执行者)eg :Many people speak Chinese.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。
eg :Chinese is spoken by many people.主语English是动词speak 的承受者。
二、被动语态的构成被动语态由“_________+________________________”构成。
人称、数和时态的变化是通过______的变化表现出来的。
(被动语态的否定式和疑问式均由助动词或第一个助动词构成。
)各种时态的被动语态构成:1.一般现在时:am /is /are +及物动词的过去分词Eg :I'm asked to take care of myself.Football is played all over the world2.一般过去时:was /were +及物动词的过去分词Eg :This house was built in 1958.His leg was broken in an accident.3.一般将来时:will /shall be +及物动词的过去分词Eg :More factories will be built in our city.He will be taken to hospital tomorrow.4.现在进行时:am /is /are being +及物动词的过去分词. Eg : A road is being built around the mountain.Many new houses are being built in this city5.过去进行时:was/were being +及物动词的过去分词Eg :The meeting was being held when I was there.We were being trained this time last year.6.现在完成时:have /has been +及物动词的过去分词Eg :His book has been translated into many foreign languages.The prices of many goods have been cut again .7.过去完成时:had been + 及物动词的过去分词Eg :A new school had been set up by the end of last year.8.含有情态动词的被动语态:情态动词+be+及物动词的过去分词Eg :The rubbish can be put into the dustbin over there.用动词show 的被动语态填空1). I know a new film_____________ at the cinema every week .2). I know a new film _____________ at the cinema lastweek .3). I know a new film _____________ at the cinema these days .4). I know a new film ___________ at the cinema at eight last night .5). I know a new film _____________ at the cinema recently .6). I know a new film _____________ at the cinema in two day .7). I know a new film___________ at the cinema by the endof lastweek .三、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。
He plant trees in spring .Trees are planted by him in spring.主动语态变被动语态口诀:宾语提前主语变,原主变宾by后见,时态人称be关键。
All the people laughed at him. →He was laughed at by all people.They make the bikes in the factory.→The bikes are made by them in the factory.He cut down a tree. → A tree was cut down by him.※注意:1). 间接宾语前需要加for的动词,buy ,sing ,catch ,find ,get,drw ,cook ,keep ,make,offer 等。
2).间接宾语前需要加to的动词,bring ,give ,pass ,hand ,leave ,show ,write ,take ,teach ,tell ,thow ,lend,send ,return等3). 如果复合宾语是由“宾语+不带to的动词不定式”构成,变为被动语态时,动词不定式前的to要补出来。
常见的这类动词有:一感(feel),二听(hear,listen to )三让(let ,make ,have )四看(watch ,see ,notice ,observe,+look at )但动词为let时,to仍可省略。
Eg:1.The story made us laugh . →We were made to laugh by the story.2.The teacher let the little boy go home . →The little boy was let (to) go home .4). 短语动词的被动语态:一般说来,只有及物动词才有被动语态,但许多“不及物动词+副词或介词”构成的短语动词,相当于及物动词,也可以有被动语态,但变被动语态后,不可把介词或副词漏掉。
Eg:1.He turned on the radio just now. →The radio was turned on just now .2.They take good care of the babies . →The babies are taken care of.3.The look after the babies . →The babies are looked after .5). 宾语从句主动变被动,有两种改写方法:.用it做被动语态的形式主语,宾语从句保持不变.※宾语从句被动语态常用特殊句式:(据说……),"It is reported that …"(据报道……),It is well known that …(众所周知……)"It is said that…"It is supposed that(据推测说……),It is believed that…大家相信,It is hoped that…大家希望,It is thought that…大家认为,It is suggested that…据建议等等’。
eg:1.It is said that she is going to be married to a foreigner.据说她要嫁给一个外国人。
2.It is said that the boy has passed the national exam. (=The boy issaid to have passed the national exam. ).将从句的主语改为被动语态的主语,从句的谓语部分变为不定式。
这时的动词不定式所用的形式要与原来的宾语从句保持一致。
Eg:They say that our teacher is busy these days . →It is said that our teacher is busy these days.Our teacher is said to be busy these days.6).如果原句宾语有后置定语修饰,变为被动语态时,应把后置修饰语随同宾语一同提前。
Eg:we clean the windows of our classroom every day . →The windows of our classroom are cleaned every day.7).by短语的取舍:当主动句中是who ,what ,which等做主语,变被动语态后句首的疑问词在句中的成分由原来的主语变为介词by的宾语,应注意介词by不能丢。
Eg:who wrote the book ? →who was the book written by ?四.可与被动语态连用的介词在被动语态的句子中,常用介词by引出动作的发出者,实际上同被动语态连用的介词除by以外还有很多。
1.表示谓语动词的动作是为谁或为何目的而发生的要用介词for。
(be used for sth /doing sth 被用于…被用于做…)Eg:1.This new bike was bought for you .2.Stamps are used for sending letters .2.表示动作发出者所使用的工具或强调状态时应用介词withEg:1.The trees were cut down with a knife .2.The bottle is filled with orange .3.表示“被作为…(发生)”应用介词as (be used as 被作为…使用)Eg:English is used as a first language in Canada.4.在be well-known 后应用介词to,表示“被…所熟知”Eg:The Great Wall is well-known to everyone in the world .5.在be made 后可用多个介词表示不同的意义1).be made in 表示“在某地制造”Eg:This Tv set is made in shanghai .2).be made of 和be made from 都可以表示“由…制成的”,但be made of 强调从制成品上可以看出原材料,be made from则表示从制成品上看不出原材料。
