重难点08 谓语动词的语态中考英语对谓语动词的考查集中在单项选择题、语法选择题、填空题和短文填空题。
考查重点包括谓语动词的时态和语态。
本专题目的在于帮助学生梳理谓语动词被动语态用法,以帮助同学们高效复习。
谓语动词的语态1.概念:英语动词有两种语态,主动语态和被动语态。
主动语态的主语是动作的执行者;被动语态的主语是动作的承受者,理解为“被……” 。
2. 结构:被动语态的结构是“be+过去分词”,be动词有时态、人称和数的变化。
当不知道动作的执行者或没必要指出动作的执行者,只强调突出动作的承受者时,用被动语态。
【易错警示】难点(1):动词短语变成被动语态时,要保持完整,不能丢掉其中的介词或副词。
如:The old are taken good care of in the old people’s home.老人们在敬老院被照顾得很好。
难点(2):省略to的动词不定式,在被动语态中要还原to。
难点(3):不用被动语态的词,常见的有:1. 五感官三变化两发生:look,smell,taste,feel,sound,become,get,turn,happen,take place。
如:The flowers smell nice.花闻起来很香。
(不能用are smelt)Great changes took place in China.中国发生了巨大变化。
(不能用were taken place)2. come out,belong to,break out,spread,appear,disappear也不用被动语态。
如:The CD came out yesterday.这个CD昨天就发行了。
(不能用was come out)3. 某些可以和“well,easily,smoothly” 连用的不及物动词,且主语是物体,不用被动语态。
这类词有:read,write,draw,wash,clean,cook,sell,lock,open,cut。
中考英语--被动语态及练习一、动词的语态语态有两种:主语是动作的为主动语态。
主语是动作的为被动语态。
1.被动语态谓语动词概述1)被动语态最基本的句型结构是:2)被动语态中的谓语动词一定要是动词,以为被动语态句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可以用于被动语态Eg. The children were taken good care of by her.3.被动语态各种结构的变化1)主谓宾S+V+DO宾语变成被动语态的,谓语部分变成对应的形式,主语用by连接作为方式状语放在句尾,通常省略。
2)主谓宾宾S+V+IO+DO通常将离动词最近的宾语变成被动语态的主语,另外一个无论是宾语还是由to或for 连接的宾语全都直接落在谓语动词被动形式后面。
3)主谓宾宾补S+V+DO+OC这个结构是被动语态中最难的一类,将宾语变成被动语态的主语,谓语动词变成对应的被动形式然后将宾语补足语(宾补)直接落下。
注意: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。
有一个顺口溜方便记忆:宾补动词真奇怪,to在句中像妖怪。
主动句中to走开,被动句中to回来。

八、动词时态【注意】(1)陈述句变一般疑问句:主语I/we变you,some变any.(2)特殊疑问句:what, when, why, who, where, how……特殊疑问词+助动词+主语+动词原形+其他?Where do you study English?特殊疑问词+be动词+主语(+其他)?Why is your mum so angry?(3) 按照时间表发生的动作,可以用一般现在时表将来The shop opens at 10am. and finishes at 5pm.【注意】(1)always也可用于现在进行时,表示一种强烈的感情色彩,译为“总是”He is always telling lies.(2)某些特殊动词不能用于现在进行时。
① have当“有”讲时,不能用现在进行时。
I have two books now.②“belong to” The two people belong to me now.③表示“心理活动/状态/感觉”的词I want a dog now.① be going to主要用于:主观判断(1)表示事先经过考虑、安排好打算要做的事情:I’m going to play the violin.(2)表示根据目前某种迹象判断,某事非常有可能发生(有迹象表明要发生的事)。
Look!There come the dark clouds. It is going to rain.② will主要用于:(1)客观上将来势必发生的事情, 未经事先考虑, 临时决定的They will go to visit the factory tomorrow.(2)表示不以人的意志为转移的自然发展的未来的事:Today is Saturday. Tomorrow will be Sunday.(3)表意愿。
问对方是否愿意做某事或表示客气地邀请或命令:Will you please turn on the radio?(1) have/has been to “去过已回”She has been to Japan twice.have/has gone to. “去了未回”Where is your twin sister? She has gone to Japan.have/has been in “待在某地” She has been in Japan for 2 years. (2) 动词从词义上可以分为延续性和非延续性两种。
专题03 动词时态及语态【考点综述】:动词是谓语动词所表示的动作或情形发生时刻的各类形式。
英语动词有16种时态,可是经常使用的只有9种:一样此刻时、一样过去时、一样以后时、此刻进行时、过去进行时、此刻完成时、过去完成时、过去以后时、此刻完成进行时。
当句子的主语是动作的执行者时,谓语的形式叫主动语态。
句子的主语是动作经受者时,谓语的形式叫被动语态。
被动语态由助动词be + 过去分词组成,时态通过be 表现出来。
动词是中考考查的重点,动词的时态和语态更是考查的重中之重。
动词不仅有人称和数的转变,而且有时态、语态、语气和非谓语形式等语法现象。
这些都是中考考查的内容。

中考英语动词语态主动与被动语态知识讲解动词的语态是各地中考单项选择题、完成句子及句型转换等题型的必考知识点之一。
考查内容主要涉及多种常见时态的被动语态。
选项的设置均为在特定语境中考查一个动词的多种时态、不同语态的意义和用法的辨析。
语句多为单句形式,在完成时态及情态动词的被动语态的句子考查中常常和宾语从句或者定语从句一起考查,而在句型转换中考查形式主要以主动语态和被动语态句型转换为主。
一、被动语态的构成【常见时态的被动语态】1.一般现在时---主动语态:do被动语态: am /is /are doneWe clean the classroom every day.我们每天打扫教室.The classroom is cleaned by us every day.教室每天都由我们打扫。
2.一般过去时---主动语态:did被动语态: was /were doneWe cleaned the classroom yesterday.昨天我们打扫了教室。

第十一章动词的语态思维导图知识梳理一、语态概述英语动词除了有时态之外,还有语态,表示主语和谓语的不同关系.如果主语是动作的执行者,谓语动词用主动语态;如果主语是动作的对象,谓语动词则用被动语态.动作的执行者用“by”引导的短语表示,但往往被省略;动作的对象则充当了被动语态句中的主语.汉语中常用“挨”“被”“受”等词来表示这个意思.The boy broke the window.那个男孩把玻璃窗打碎了.(主动语态)The window was broken by the boy.这扇玻璃窗被那个男孩打碎了.(被动语态)They watched the children sing that morning.那天早上他们看着孩子们唱歌.(主动语态)The children were watched to sing that morning.那天早上,孩子们被观看唱歌.(被动语态)二、被动语态的构成“助动词be+(及物动词的)过去分词”构成动词被动语态的形式.助动词be有人称、数和时态的变化,其变化规则与be作为系动词的变化完全一样.现以动词ask为例,列表如下:方式(一)一般现在时This kind of TV set is made in Guangzhou.这种电视是广州制造的.Chinese is spoken by the largest number of people in the world.汉语是世界上最多人讲的语言.(二)一般过去时The thief was arrested.小偷被抓住了.These pictures were taken on the Great Wall.这些照片是在长城拍摄的.(三)一般将来时Your watch will be repaired.你的表将会被修理好.The class meeting will be held next Saturday afternoon.班会下周六下午召开.(四)现在进行时A new road is being built outside my house.我们家门口正在修一条新路.The watch is being repaired.这只表正在修理.(五)过去进行时The bridge was being repaired when we passed it.我们过桥时,桥正在修.While the supper was being prepared,the light suddenly went out.正在做晚饭时,电灯突然灭了.(六)过去将来时They decided that invitations would not be sent out unless they were carefully checked.他们决定除非经过仔细校对,否则请柬不会发送出去.(七)现在完成时Your wallet has been found.你的钱夹已经找到了.Enough has been said here of this question.关于这个问题,这里已经谈得不少了.(八)过去完成时By1972a cooperative medical system had been set up in this area.到1972年这个地区已建立了合作医疗制度.When the anthem had been played,the Congress began.奏完国歌后,大会开始.四、被动语态的用法(一)不知道谁是动作的执行者,用被动语态My watch was stolen.我的手表被窃了.This jacket is made of cotton.这件夹克是棉制的.Her son was killed in World War II.她的儿子在第二次世界大战中战死.(二)没有必要或不想指出谁是动作的执行者,用被动语态The children have been very well looked after.孩子们得到很好的照顾.A big building has been put up in my home town.我家乡已经建起一座大楼.Many thousands of trees must be planted every year.每年必须种很多树.This hat was made in China.这顶帽子是中国制作的.The bicycles must not be put here.这儿不准放车.(三)强调或突出动作的承受者时,用被动语态The letter was posted.信发了.She was asked to sing a song.她被要求唱支歌.He cannot be relied on.他不可靠.A liar is looked down upon.说谎的人被人看不起.(四)出于礼貌措辞等原因不愿说出动作的执行者Anyone who sees the lion is asked to telephone the zoo and the police.有谁看见这只狮子,请给动物园和警方打电话.You are wished to do it more carefully.希望你认真一点做.(五)为使句子结构简练、紧凑,上下连贯,也即出于行文的需要When he was still a young man,he was forced to leave his home land for political reasons.他年轻时,就由于政治原因被迫离开了祖国.Lenin often talked to his comrades and was always listened to attentively.列宁经常和同志们谈话,同志们总是留心听他说.(六)在文章标题、广告、新闻等中常用省略助动词be的被动语态Telephone call placed.(TCP)电话接通了.(省略了has been)Girls Wanted.招女工.(广告用语,省略了are)Road Blocked.道路堵塞.(新闻报道,省略了is)五、含有情态动词的被动语态情态动词的被动语态,其结构是:情态动词+be+过去分词.Young trees cannot be cut down.小树不可以砍伐.The exercises must be done in class.练习必须在课堂上做.This dictionary must be taken good care of.这本词典必须保管好.The time in class must be made good use of.上课的时间必须好好地利用.六、主动形式表示被动意(一)某些由及物动词转化来的不及物动词read,write,clean,wash,iron,burn,draw,cook,keep,cut,open,blow,peel,sell,act等,常和副词well,easily, smoothly等连用,且通常用主动结构表示被动含义.The pen writes

cooking.午饭正在烧.(四)某些系动词如feel,prove,smell,taste,sound等加上形容词,也可用主动语态表示被动意义.如:The food tastes delicious.这食物味道很美.七、主动语态变为被动语态的方法把主动语态的结构变为被动语态结构时,要做如下的变动:(一)主动结构的宾语变为被动结构的主语(二)主动结构的谓语动词由主动语态变为被动语态结构的谓语动词(be+动词的过去分词)(三)主动结构的主语变为介词“by”的宾语,组成介词短语,放在被动结构中谓语动词之后.若动作的执行者无须说明或不必强调时,by组成的短语就可以省略(四)主动语态变被动语态时,时态要保持一致(五)含有直接宾语和间接宾语的主动结构,变为被动结构时,可以将其中一个宾语变为被动语态的主语,另一个不动.一般是将主动结构的间接宾语变为被动结构的主语,这样句子显得自然一些Books and newspapers in the reading room mustn't be taken away.阅览室的书和报纸都不能带走.This kind of bike is not made in our factory.这种自行车不是我们厂生产的.This picture can't have been drawn by him.这张画不可能是他画的.When was that book published?那本书是什么时候出版的?Shall we be asked to attend the opening ceremony?会邀请我们参加开幕式吗?点拨(1)带双宾语的谓语动词变为被动语态时,既可以将间接宾语转化成主语,也可以将直接宾语转化成主语.若将间接宾语转化成主语,则保留直接宾语;若将直接宾语转化成主语,则保留间接宾语,且在被保留的间接宾语前加上介词to或for.常见的能接双宾语(直接宾语和间接宾语)的词有:give,show,bring,lend,send(送,寄)等,这些词与介词to 搭配.还有buy,make,draw(画画)等,这些词与介词for搭配.We gave them some books.我们给了他们一些书.They were given some books.(变间接宾语为主语)Some books were given(to)them.(变直接宾语为主语)(2)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.但如果宾语补足语是不带to的动词不定式,句子变成被动语态后则要加to,以便将两个动词隔开.We keep food cold in the fridge.=→Food is kept cold in the fridge.我们用电冰箱保鲜食品.Every day the tiger makes one of the smaller animals bring him something to eat.=→Every day one of the smaller animals was made to bring the tiger something to eat.老虎每天强迫一个小动物给他带吃的东西来.(3)短语动词的被动语态短语动词在主动结构中是一个不可分割的词组,在被动结构中也是如此,不可丢掉后面的介词或副词.The nurse takes good care of the children.阿姨很好地照顾小孩.The children are taken good care of by the nurse.孩子们受到保姆很好的照顾.八、系表结构和被动语态的区别(一)系表结构通常只用于一般现在时或一般过去时,而被动结构可用于多种时态(二)系表结构中的过去分词常常有其固定的介词搭配,被动结构则没有(三)系表结构中的过去分词可被very等副词修饰;被动结构中的过去分词可用much修饰.比较:The husband was very agitated about his wife's health.丈夫为他妻子的健康状况深感不安.(系表结构)Milk,meat,eggs and vegetables are produced in the farm.这个农场盛产牛奶、肉,鸡蛋和各种蔬菜.(被动结构)They were asked to speak at the meeting.他们被邀请在会议上讲话.(被动结构)He was puzzled about it.他为那件事感到困惑.(系表结构)九、不能使用被动语态的情况(一)某些表示状态的及物动词作谓语时常见的表示状态的及物动词有have(有),fit(适合),suit(适合),hold(容纳),cost(花费)等.The room can hold100people.这个房间能容纳100人.(二)宾语是反身代词或相互代词、表示地点或处所的名词时,不可用于被动语态在黑暗中我们几乎看不到对方.We could hardly see each other in the dark.(✓)Each other could hardly be seen in the dark.(x)(三)宾语是不定式短语或动名词时汤姆喜欢听音乐.Tom enjoys listening to music.(✓)Listening to music is enjoyed by Tom.(x)好题精练一、将下列句子变为被动语态1.Everybody respects the brave old man.____________________________________________________________________________________________ 2.We elected Comrade Li head of our

中考英语动词的语态一、动词的被动语态1.主动语态和被动语态英语语态有主动语态和被动语态两种。
主语是动作的执行者,叫做主动语态;主语是动作的承受者,叫做被动语态。
例如:We swept the floor.我们打扫了地板。
(主动语态)The floor was swept.地板被打扫过。
(被动语态)2.被动语态的构成1)被动语态是由“助动词be+及物动词的过去分词”构成的。
助动词be有人称,数和时态的变化,其变化规则与其作为连系动词的be的变化完全一样。
被动语态的肯定式的结构是:主语+be+过去分词(vt.)+(by+宾语)。
例如:Apple trees are planted in China..苹果树不种在南方。
2) 被动语态的否定句The building hasn't been completed.这座建筑物没有竣工。

--Was the museum built in 1993? 这座博物馆是在1993年建成的吗?--No, it was built in 1986. 不,它是在1986年建成的。
4)被动语态的特殊疑问句被动语态的特殊疑问句的结构是:疑问词+be+主语+过去分词(vt),其答语要作具体回答。

2)把主动结构的谓语动词改为be+过去分词形式。
3)将主动句的主语变为介词by的宾语。
例如:People use radios for listening to the news.(主动)→Radios are use for listening to the news by people.(被动)I posted a letter last week.(主动)→A letter was posted by me last week.(被动)注意:在make, let, see, hear, notice, watch, feel等动词后面作宾语补足语的动词不定式都不带to,但这种句子如果变为被动语态时,则应加上to。
例如:We heard her sing an English song.(主动)→She was heard to sing an English song by us.(被动)5.主动语态变为被动语态的主要类型1)谓语动词只有一个宾语的。
例如:The workers are building a ship.(主动语态)→The ship is being built by the workers.(被动语态)I have finished the exercises.(主动语态)→The exercises have been finished by me.(被动语态)2)谓语动词有两个宾语的,其中一个变为被动句的主语,另一个仍作为宾语,称为保留宾语。
例如:I sent him a present. (主动语态)→He was sent a present by me.(被动语态)A present was sent to him by me.(被动语态)注意:a)在主动句中有些动词,如ask, answer, teach等变成被动句时,一般将间接宾语(指人的)改成被动句的主语。
例如:He asked us a lot of questions.(主动语态)→We were asked a lot of questions by him.b)在主动句中有些动词,如build, buy, choose等变成被动句时,将直接宾语(指物的)改成被动句的主语。
例如:My father bought me a new bike.(主动语态)→The new bike was bought for me by my father.(被动语态)3)谓语动词后跟复合宾语,只把宾语改为被动句的主语,宾语补足语不变。
例如:宾语宾补He left the door open.(主动语态)他让门开着。
→The door was left open by him.(被动语态)门由他打开着。
4)许多由不及物动词加介词构成的短语动词,相当于一个及物动词,可以有宾语,因而也可以有被动语态。
但应注意:短语动词是一个不可分割的整体,在变为被动语态时,不可丢掉构成短语动词的介词或副词。
例如:We must take good care of our books.(主动语态)→Our books must be taken good care of.(被动语态)我们应该保管好我们的书本。
我们的书本应保管好。
(被动)6.被动语态中应注意的几个问题1)在被动语态句子中要注意主语与谓语在人称和数方面要保持一致。
2)主动语态不能变为被动语态的情况:a.have(有)以及和have构成的短语动词不能用于被动语态b.不及物动词没有动作的承受者,不能用被动语态。
c.主动句的宾语是each other或反身代词时,不能变成被动句的主语。
d.主动句的宾语是不定式或动词的-ing形式时,不能变成被动句的主语。
3)注意有时用主动语态表示被动意义的情况。
