初中英语-被动语态知识点及练习(无答案)学案
展开1.掌握一般现在时、一般过去时、一般将来时的被动语态的构成和基本用法。
2.掌握带有can,may,must等情态动词的被动语态的构成和基本用法。
主动语态
一.被动语态的定义
被动语态
语态是动词的一种形式,它表示主语和谓语的关系。 语态有两种:
如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态;
如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态。
口诀: 谁做动作不知道,说出谁做没有必要; 动作承受者需强调,被动语态运用到。
二.被动语态的构成
被动语态由“be+过去分词”构成,在句中be动词要有人称和数的变化。
【口诀】:被动语态be字变,过去分词跟后面。
主动语态和被动语态的转换
(一)主动语态变被动语态
1.把主动语态的宾语变为被动语态的主语,宾格变为主格。
2.把谓语变成被动结构(be+过去分词)。
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。
【口诀】: 宾变主,主变宾,by短语后面跟。 谓语动词变被动,be后“过分”来使用。
例如: He mended the bike yesterday.→
主 谓 宾 、
The bike was mended by him yesterday.
主 宾
(二)含有情态动词的被动语态
含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带t情态动词变成被动语态后“t”要保留。
【口诀】情态动词变被动, 情态加be加“过分”, 原来带t要保留。
例如: We have t lk after the dg.→ The dg has t be lked after by us.
(三)含有宾语补足语的被动语态
含有宾语补足语的句子,宾语变为主语后,宾语补足语改为主语补足语,原来的位置一般不变。例如:
We keep fd cld in the fridge.→ Fd is kept cld in the fridge.
注意:
主动句中的宾语补足语如果是不带t的不定式,在变成被动句中的主语补足语时,t不能省去。例如:
She heard him sing a sng just nw.→ He was heard t sing a sng just nw.
基础过关
1.—Hw beautiful yur hmetwn is!
—Yes,a number f trees ____ arund Dazhu every year.Our envirnment is getting better and better.
A.are plant B.are planted C.are planting D.were planted
【解析】答案为B。本题考查的是一般现在时的被动语态。根据“every year(每年)”可判断用一般现在时,又因主语“a number f trees(大量的树)”是谓语动词“plant(种植)”的承受者,用被动语态,一般现在时的被动语态为:am/is/are+dne
2. —David,turn ff the TV ____ n ne is watching it. —But it ____ ff already! The music is frm the radi.
A.s that;has been turned B.when;has turned C.if;has been turned D.because;has turned
【解析】答案为C。本题考查现在完成时的被动语态。第二句中的it指代的是前句所说的TV,故与turn ff之间为被动关系,又因为already为现在完成时的标志,故排除B、D两项;又根据第一句话可知“如果没有人在看电视的话,就把电视关上吧。”
3. —Wuld yu like t g t the mvie with me? —Srry,I ____ t g ut tnight.
A.wn’t be allwed B.am allwed C.dn’t allw D.will allw
【解析】答案为A。本题考查的是一般将来时的被动语态。be allwed t d sth.是“被允许做某事”的意思,根据句意“你愿意和我一起去看电影吗?”“对不起,今晚我不被允许外出。”可知用被动语态的否定形式,根据tnight(今晚)判断用一般将来时,一般将来时被动语态的否定结构是:will nt be+dne,故选择A。
4.—Mm,can I g ut t play basketball? —Sure.But yur hmewrk ____ first.
A.must be finished B.must finish C.will finish D.finish
【解析】答案为A。本题考查的是含有情态动词的被动语态。主语“yur hmewrk(你的作业)”是谓语动词finish(完成)的承受者,其句意是“但是你的作业必须首先被完成。”用含有情态动词的被动语态的结构为:情态动词+be+dne,故选择A。
5. It’s cmmn knwledge that black tea ____ in China mre than 600 years ag.
A.is invented B.was invented C.invents D.invented
【解析】答案为B。本题考查的是一般过去时的被动语态。根据“mre than 600 years ag(600多年前)”判断用一般过去时,又因主语“black tea(红茶)”是谓语动词invent(发明)的承受者,故应用一般过去时的被动语态,其结构是:was/were+dne
能力提高
1.Dn’t put ff tday’s wrk fr tmrrw.I mean.tday’s wrk ____tday.
A.may d B.must d C.may be dne D.must be dne
【解析】不要把今天的工作推到明天,我的意思是今日的工作今日毕。因此应该用must ,wrk和d 的关系是被动。因此选择D。 I mean,是常见的插入语。
2. The number f deaths frm heart disease will be reduced greatly if peple t eat mre fruit and vegetables.
A.persuade B. will persuaded C. be persuaded D.are persuaded
[解析]尽管句中是指将来的事情,但条件状语从句中常用一般现在时代替一般将来时,在这时“如果人们被说服或被劝告……”含有被动之意,所以用一般现在时的被动语态。
3. Millins f punds’ wrth f damage by a strm which swept acrss the nrth f England last night.
has been caused B. had been caused C.will be caused D. will have been caused
【解析】 损失是暴风雨造成的,所以应该是被动。 但如果被题干中的过去时迷惑而用过去完成时B选项就错了。 暴风雨是昨晚发生的事情,但是由此造成的影响还在继续,所以应当用现在完成时的被动语态。
4. The mayr f Beijing says that all cnstructin wrk f the Beijing Olympics by 2015.
A. has been cmpleted B. has cmpleted C. will have been cmpleted D. will have cmpleted
【解析】题干中有明显的时间状语by 2015,是一个将来的时间。 短语by+将来时间和将来完成时连用,同时cnstructin 和cmplete 是被动关系, 故用将来完成时的被动语态。
5. Mary g shpping with Tm in Qingda last week
A.was seen t B.was seen C.has been see D.has seen t
【解析】 see sb. d sth. 看到某人做某事。被动的时候t 要加回来。所以应该是 sb. be seen t d sth. last week 是一个很明显的过去时的时间状语。 所以用be 动词的过去形式,was/were Mary 是第三人称所以用was.
1.被动语态介词固定搭配不能省略。
He has thught f a way f slving the prblem.
A way f slving the prblem has been thught f.
2.break ut/ happen/ take place/ arrive/ becme/ die/ disappear etc 不及物动词没有被动语态
The accident which happened yesterday surprised me.
3.带双宾语的动词give /send/bring/ take/teach/shw/ tell/ make/ sing/ write/ sell/buy/ ask/ pay/ brrw/ lend/ hand/ ffer/prvide/ past/get/prmise
变被动语态有两种方法:
1. I have given him the bk.=He has been given the bk.=The bk has been given t him.
2. My father bught me a present n my last birthday.
(1)I was bught a present by my father n my last birthday.
(2)A present was bught fr me by my father n my last birthday.
4、其他形式表示被动结构
“be +under/ in等介词+名词”结构可代替进行时被动语态。
The city is under attack at the mment=The city is being attacked at the mment .
The bridge is under repair.=The bridge is being repaired.
The prblem is under discussin at the meeting. =The prblem is being discussed .
5.表示状态特征的连系动词+adj./n., 用主动式表被动义。
(lk, sund, feel, smell, taste, prve, appear,...)
The steel feels cld.=This kind f clth feels sft.
That dg lks dangerus.
My advice prved t be wrng.
6) 表示主语的属性特征的动词+副词well/ badly/easily/smthly,用主动式表被动义。
(read, write, sell, wash, clean, wear, pen, ck, lck, shut, dry, eat,drink,...)
The pen writes smthly.
The clth washes well.
The pem reads smthly.
The bk sells well.
This shirt will wear very lng.

The wall wants repairing /t be repaired.

2. ---- The windw is dirty.---- I knw. It ________ fr weeks.

3. --- Gerge and Lucy gt married. Did yu g t their wedding?--- N, I ___________. Did they have a big wedding?
A.was nt invited B. have nt been invited C. hadn’t been invited D. didn’t invite
