初三英语被动语态与主动语态转换单选题40题(含答案)
初三英语被动语态与主动语态转换单选题40题(含答案)1.The blackboard is cleaned by the students every day. The students ______ the blackboard every day.A.cleanB.cleansC.are cleaningD.cleaned答案：A。
一般现在时的被动语态结构是am/is/are + 过去分词，主动语态结构是主语+动词原形/动词第三人称单数形式。
此句中被动语态is cleaned 的主动形式是clean，因为主语the students 是复数，所以用动词原形clean。
B 选项cleans 是第三人称单数形式；C 选项are cleaning 是现在进行时；D 选项cleaned 是一般过去时。
2.The classroom is swept by us after school. We ______ the classroom after school.A.sweepB.sweepsC.are sweepingD.swept答案：A。
理由同上，被动语态is swept 的主动形式是sweep，主语we 是复数，用动词原形。
B 选项是第三人称单数形式；C 选项是现在进行时；D 选项是一般过去时。
3.The books are put on the shelf by him. He ______ the books on theshelf.A.putB.putsC.is puttingD.putted答案：A。
被动语态are put 的主动形式是put，主语he 是第三人称单数，但put 的过去式和原形一样，这里是一般现在时，所以用put。
B 选项puts 是第三人称单数形式错误使用；C 选项is putting 是现在进行时；D 选项putted 错误，put 的过去式还是put。
4.The windows are opened by the teacher in the morning. The teacher ______ the windows in the morning.A.openB.opensC.is openingD.opened答案：B。
英语初中被动语态及练习题(含答案)
一、被动语态概述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，一般来说，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”等词来表示被动意义。
如：He opened the door.他打开了这扇门。
（主动语态）The door was opened.这扇门被打开了。
（被动语态）二、被动语态的构成被动语态由“助动词be+及物动词的过去分词”构成。
被动语态的时态变化只改变be的形式，过去分词部分不变。
疑问式和否定式的变化也如此。
1、被动语态的时态较常见的八种，现以动词clean为例列表说明：1) am/is/are +done (过去分词) 一般现在时例Visitors are requested not to touch the exhibits.2） has /have been done 现在完成时例All the preparations for the task have been completed, and we're ready to start.3） am/is /are being done 现在进行时例A new cinema is being built here．4） was/were done 一般过去时例I was given ten minutes to decide whether I should reject the offer.5） had been done 过去完成时例 By the end of last year, another new gymnasium had been completed in Beijing.6） was/were being done 过去进行时例A meeting was being held when I was there.7） shall/will be done 一般将来时例Hundreds of jobs will be lost if the factory closes.8） shall/will have been done 将来完成时例The project will have been completed before July.2、被动语态的句式变化：以一般现在时和动词invite为例，列表说明被动语态的句式变化：3、含有情态动词的被动语态情态动词的被动语态结构为：情态动词+be+过去分词；其时态及句型的变化仅由情态动词完成，“be+过去分词”部分不变。
初中英语被动语态(知识点+练习题,含答案)
被动语态全解语态是动词的一种形式,表示句子中主语和谓语动词的关系,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。
只有及物动词才能用于被动语态。
一．被动语态的时态：1.一般现在时的被动语态： am /is/ are +动词的过去分词2.一般过去时的被动语态： was /were +动词的过去分词3.一般将来时的被动语态： will be +动词的过去分词4.现在进行时的被动语态： am /is /are +being +动词的过去分词5.现在完成时的被动语态： have /has +been +动词的过去分词6.情态动词的被动语态：情态动词 + be +动词的过去分词二．被动语态的基本用法:(1) 需要强调动作的承受者时The Great Wall is enjoyed by millions of people all over the world English is widely spoken in the world now.(2) 不知道或没必要指出动作的执行者时Mr. Wang is invited to the meeting today .The problem is dealt with now .(3) 当说话人需要强调客观时It is said that she was a beauty when she was young .三．主动主动语态变被动语态的变法：口诀：宾变主，主变宾，谓变be done ,时不变，数格必须随被变。
注：1.主动、被动的时态要一致。
2.主动、被动的句式要一致。
3.变成的被动语态的主语与谓语在单复数上保持一致。
语态转换不被动语态的步骤1, 把原主动句中的宾语转换为被动语态的主语2, 把动词改为被动语态形式即"be+过去分词"。
3, 原来主动语态句子中的主语,如果需要就放在by的后面以它的宾格形式出现(因为by是介词,后面需跟宾格作介词的宾语。

被动语态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。
女口: 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”，相当于中文中常说的“被……”、“由……”的句式，女口：“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 ope ned the doo他开了门。
( ____________ )The door was ope ned'.l 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.Pam (is,are) 现在时，am (is,are) +P.Pwas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,mus) 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. —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. —般将来时：shall/will/be goi ng 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 + be in g+过去分词肯定句： A car is being _________ （ d ri ve）n ow .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+ bee n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.P1）This clock can be _______ （repair）here.2）The trees may be _______ （_ plant）at other times of the year.3）The composition must be ________ （h a nd）i n 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 _________ （pu b l i s h ）i n 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 _________ （b re ak）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 guaranteec每天8 小时睡眠必须得至U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, hea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 outsid(e by him) .I saw him play football. —He was seen to play footbal(l by him) .专项练习一、选择题( )1. _____ a new library ____ in our school last year?A.
