初三英语被动语态

课 题 被动语态的考点解析 教学目标 掌握被动语态的用法 教学内容 ‎【温故知新】‎ 批注:我们见过很多街头艺人,在大街上画出的立体画非常的逼真,很多人都会认为是真的,而从旁边绕过去,所以我们被欺骗啦! We are cheated! 这样的表达,就是我们今天要讲的内容——被动语态 ‎【知识梳理】‎ 知识点1:被动语态的基本知识 ‎1. 语态:英语的语态是通过动词的形式表现出来的,用来表明主语与谓语动词之间的关系,英语的动词有两种语态形式,即主动语态和被动语态。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,谓语动词用被动语态。‎ ‎2. 主动语态与被动语态的转化:‎ ‎①将主动语态的宾语改为被动语态的主语;②将主动语态的谓语动词改为“be+过去分词”结构;③将主动语态的主语改为介词by之后的宾语,放在谓语动词之后(有时可省略)。‎ 例: We visited that factory last summer. 主动语态 主语 谓语 宾语 状语 That factory was visited by us last summer 被动语态 ‎ 主语 谓语 宾语 状语 ‎3. 用法:‎ 被动语态常用于以下两种情况:‎ ‎(1)不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者;‎ 例:This cloth is made of cotton. ‎ ‎(2)强调动作的承受者。‎ 例:Her bike is stolen . ‎ 知识点2:被动语态在各种时态下的构成 时态 结构 例句 一般现在时 am/is/are +过去分词 We are taught English by her.由她教我们英语。‎ 一般过去时 was/were+过去分词 A present was given to me by Mary.玛丽给了我一件礼物。‎ 一般将来时 will/shall/be going to be+过去分词 The desk will be mended by him.这张桌子将由他修理。‎ 现在进行时 am/is/are +being + 过去分词 The walls are being painted now.正在粉刷墙壁。‎ 过去进行时 was/were +being + 过去分词 The talk was being given at this time yesterday.昨天这个时候正在作报告。‎ 现在完成时 have/has been+过去分词 The flowers have been watered.这些花已经被浇了。‎ 过去完成时 had been+过去分词 She said this lift had never been used.‎ 过去将来时 would/should/be going to be+过去分词 The film would be shown again sometime next week. 这部电影下周的某个时候又将上映。‎ 情态动词 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)‎ 例1:Tables can be made of stone.桌子可由石头制造。‎ 例2:Tables could be made of stone at that time. 那时桌子可由石头制造。(一般过去时)‎ 例3:Can tables be made of stone? 桌子能用石头制造吗?(疑问句)‎ ‎ 批注:这里可以跟学生一起回顾一下动词的原形、过去式和过去分词,避免混淆。‎ ‎【例题精讲】‎ 单选题 例1:(2012福建福州) — Our classroom____________every day.‎ ‎ — So it is. It's our duty to keep it clean and tidy.‎ A. cleans B. is cleaning C. is cleaned D. cleaning 解析:答案C。our classroom做主语,很明显是“被打扫”,并且根据语境是一般现在时态,所以用一般现在时态的被动is cleaned。‎ 例2:(2013陕西)The mobile phone has influenced people’s life a lot since it _________.‎ A. invents B. invented C. is invented D. was invented ‎ 解析:答案D。考查动词时态和语态。句意:自从手机发明后,它在很大程度上影响了人们的生活。根据句意判断用一般过去时,手机与动词invent在逻辑上是被动关系,所以用一般过去时的被动语态。‎ 例3:(2013江苏南京)It is said that an Asian Culture Village inside the AYG, Village in Nanjing in the coming Asian Youth Games period.‎ A. builds B. is building C. will be built D. was built 解析:答案C。考查动词的被动语态用法。an Asian Culture Village(亚洲文化村)与动作build构成被动关系,所以应使用被动语态,故排除A、B项;又据句中in the coming Asian Youth Games period可知为将来时间,所以选择答案C。‎ 例4:(2013内蒙古呼和浩特) People who ________ to the party are very excited. ‎ A. have invited B. has been invited C. will invite D. have been invited ‎ 解析:答案D。考查被动语态的用法。根据句意“已经被邀请去参加聚会的人非常激动。”可以判断须用现在完成时的被动语态。B和C选项为主动语态,但是动词invite没有宾语,故排除;而B选项中,has和主语people不能搭配。所以选择答案D。‎ ‎ ‎ 例5:(2013湖北黄冈)—How often do I need to feed the dog?‎ ‎ — It ___ food every day, or it will be hungry.‎ A. must give B. must be give C. must be given D. must be gave ‎ 解析:答案C。考查情态动词的被动语态。 它每天必须被喂食,应用被动语态,其构成是be+过去分词,故选C。‎ 例6: The new suspension bridge ___ by the end of last month.‎ A. has been designed  B. had been designed C. was designed   D. would be designed 解析:答案B。根据“by the end of last month”,所以用过去完成时,又因为这座新桥是被设计的,所以综合来看,用过去完成时的被动语态。‎ 例7:用括号内动词的适当形式填空 ‎1.she _______________ (tell) the good news as soon as it arrived.‎ ‎2.A lot of work __________________(do) for the poor kids in the past few years.‎ ‎3.The book ________________ (write) by the young girl several years ago.‎ ‎4.All the tickets __________(sell) out when we got to the cinema.‎ ‎5.A new building __________(build) at our school now.‎ ‎6.I don't believe you've already finished reading the book which ________(lend) to you this morning!‎ 解析:‎ 1. 答案was told。首先根据“as soon as it arrived”,判断时态是一般过去时,而句意是“她被告知这个好消息”,所以用一般过去时的被动语态。  ‎ 2. 答案has been done。由时间状语可知需要用现在完成时态,句意是“大量工作已经被做”,所以用被动语态。 ‎ 3. 答案was written。“several years ago”,可判断时态为一般过去时,“书是由一个年轻女孩所写”,应用被动语态。 ‎ ‎4. 答案had been sold。“在他们到达电影院的时候,票已经卖完了”,这里“到达”已经是过去时,所以票卖完了是在到达之前发生的,所以用过去完成时的被动语态。  ‎ ‎5. 答案is being built。由now可知需用现在进行时态,新桥是“被建造”,所以用现在进行时态的被动语态。 ‎ ‎6. 答案 was lent。由this morning可知时态为一般过去时,而书“被借出”,用被动语态。‎ 例8:把下列句子改为被动句 1. John drew a beautiful horse last week.‎ 2. The children will sing an English song.‎ 3. People use metal for making machines.‎ 4. He asked me to do that for him.‎ 5. They sold out the light green dresses. ‎ 答案:1. A beautiful horse was drawn by John last week.‎ ‎ 2. A English song will be sung by the children.‎ ‎ 3. Metal is used for making machines by people.‎ ‎ 4. I was asked to do that for him.‎ ‎ 5. The light green dresses were sold out by them.‎ 例9:用括号内所给动词的正确形式填空。‎ ‎1.It's said that the long bridge______________(build)in two months. ‎ ‎2.Where to have the meeting ______________ (discuss)now. ‎ ‎3.Which language _______the most widely_______(speak)in the world? ‎ ‎4.The lost boy_____________(not find)so far. ‎ ‎5.Last year a large number of trees______________(cut)down. ‎ 解析:‎ 1. 答案will be built。根据后面的in two months可判断时态为一般将来时,再根据主语是bridge,可知桥是被建造的,所以用一般将来时的被动语态。‎ ‎2.答案is being discussed。这里主语是疑问词引导的不定式做主语,谓语动词用三单形式, 再看最后的时间状语是now,所以用现在进行时的被动语态“is being discussed”。‎ 3. 答案is spoken。句意是“哪种语言在全世界最广泛的被说”,这是一种常识性的是奇怪,所以用一般现在时的被动语态。 ‎ 4. 答案hasn’t been found。首先根据后面的“so far”,判断时态为现在完成时,再根据主语是单数,可以判断用“hasn’t been found”。‎ ‎5. 答案were cut。时间状语“last year”,可判断时态为一般过去时,主语是很多树,所以用were cut,这里需要注意cut的原形、过去式和过去分词拼写是一样的。‎ 例10:单选题 ‎ ‎1. The decision about the price ______ in a few days. So they have to wait.(2013年白下区中考一模)‎ A. is made B. was made C. is being made D. will be made ‎ 解析:答案D。根据后面“in a few days”,判断是一般将来时。这个决定是“被做”,所以用一般将来时的被动语态。‎ ‎2. If city noises ____ from increasing,people will have to shout to be heard even at dinner.‎ A. are not kept  B. are not keep C. do not keep   D. do not kept 解析:答案A。这里首先是条件状语从句,遵循“主将从现”原则,所以if从句里面用一般现在时态的被动。‎ ‎3. The fifth generation computers, with artificial intelligence, ____and perfected now.‎ A. developed    B. have developed C. are being developed   D. will have been developed 解析:答案C。句意是“第五代电脑正在发展和完善”,有被动意思,而且有now这个时间状语,所以用现在进行时态的被动语态。‎ ‎4. --- ____ the sports meet might be put off.‎ ‎ --- Yes,it all depends on the weather.‎ A. I've been told B. I've told  C. I'm told D. I told 解析:答案A。这里说的是运动会这个消息,我是“被告知”的,所以用被动语态,所以排除B和D。再根据句意,被告知这个事情已经发生了,强调对现在所造成的影响,所以需要用现在完成时态。‎ ‎5. I need one more stamp before my collection ___.‎ A. has completed B. completes  C. has been completed D. is completed 解析:答案D。这里也需遵循“主将从现”原则,before引导的从句中需用一般现在时,所以用一般现在时的被动语态。‎ ‎6. Rainforests ___ and burned at such a speed that they will disappear from the earth in the near future.‎ A. cut B. are cut   C. are being cut D. had been cut 解析:答案C。句意是“雨林正在以很快的速度被砍伐和焚烧”,所以用现在进行时的被动语态。‎ ‎7. When a pencil is partly in a glass of water, it looks as if it ____.‎ A. breaks B. has broken  C. was broken D. had been broken 解析:答案C。这里的意思是“当铅笔一端被放在一杯水里的时候,看起来就好像被折断了”,又因为这里涉及as if后面需要用虚拟语气,所以时态需比主句往后退一格,因此用过去时态的被动语态。‎ ‎【举一反三】‎ 知识点1:‎ ‎①不及物动词不用于被动语态,如appear, rise, come out, happen, occur, lie, take place等不及物动词不能用于被动语态。‎ 例1:Great changes______________place. Many new schools ______________. A. have taken, have been opened    B. take, are open C. are taken, open          D. have been taken, are opened ‎ 解析:答案A。因为take place没有被动语态,所以排除C和D,又因后句中很多新学校开了,这里需要被动,而且表示到现在为止已经开了,所以用现在完成时态的被动语态。综合选择A。‎ 例2:A strange thing _____ in our school yesterday. A. was happened    B. has been happened    C. happened   D. was going to happen 解析:答案C。因为happen没有被动语态,所以排除A和B。又有yesterday,可判断时态是一般过去时,所以选C。‎ ‎②表状态动词不用于被动语态,常见的有:hold, have, cost, contain, become, look like等 例1:这本书花了我20元。(用cost翻译)‎ ‎____________________________________________________‎ 解析:答案The book cost me 20 yuan。因为主语是书,很可能有的同学会写成“The book was cost 20 yuan.” 可是cost这里表状态,不用于被动态。‎ 例2:That suit __ over 60 dollars.‎ A. had costed B. costed C. is costed D. cost 解析:答案D。因为cost这个词不需要用被动语态,所以这里的主语是单数,可以用costs(一般现在时)或cost(一般过去时),根据选项,只能选D。‎ 知识点2:主动形式表被动意义。‎ ‎1)某些感官动词和系动词接形容词可以表示被动意义。如:look, smell, taste, feel, prove, wear, sound等 例:Her bedroom looks very clean and tidy.她的卧室看起来非常干净和整洁。‎ ‎2)某些作表语的形容词后,用不定式主动形式表示被动意义。‎ 例:The conversation is hard to understand.对这话很难理解。‎ ‎ The fish is not easy to fish.鱼不容易钓。‎ ‎ The passage is difficult to read.这段文章很难读懂。‎ ‎3)动名词的主动形式表示被动语态。如:need, require, worth等,并且可相互转化,如need doing = need to be done。‎ 例:The book is worth reading.这本书值得一读。‎ ‎ The children need looking after.孩子们需要照看。‎ 4) write, sell, wash和read和副词连用,主动语态表被动意义。‎ 例:The pen writes smoothly. 这笔写起来很顺手。‎ ‎ The article reads well. 这篇文章读起来很好。‎ 例1:--- Do you like the material?  ‎ ‎ --- Yes, it ___ very soft.  A . is feeling B . felt C . feels D . is felt  ‎ 解析:答案C。这道题首先根据选项看出考查的是feel的用法,它属于系动词,无被动,无进行时,所以排除 A,D,然后根据前一句话的时态确定选择C。 ‎ 例2:It is difficult for a foreigner ____ Chinese.‎ A. write B. to write  C. to be written D. written 解析:答案B。作表语的形容词difficult后不定式to write主动形式表示被动意义。‎ 例3:The composition doesn’t____any more. ‎ A. need to be correcting    B. need to be corrected ‎ C. need be corrected     D. need be correcting 解析:答案B。因为need doing sth = need to be done,这里只有B正确,如果变成need doing sth,可以换成need correcting。‎ 例4:--- What do you think of the book?  ‎ ‎ ---Oh, excellent. It's worth ___ a second time.  ‎ A . to read  B . to be read  C . reading  D . being read ‎ 解析:答案C。本题通过后面的回答可以很明显看出是be worth的考点,首先后面接doing,然后根据它的主动表被动的特点,排除D。‎ 例5:The kind of cloth ________ well.‎ A. wash B.is washed C.washes D.is washing 解析:答案C。本题的考点是wash后接副词,表示耐洗,主动形式表被动语态,因为cloth不可数,所以谓语动词用三单形式。‎ 知识点3:及物动词后跟双宾语的句子,被动语态有两种。‎ 常见的有:‎ 主动语态 被动语态 bring sb. sth. 把某物带给某人 sb be brought sth / sth be brought to sb ‎ lend sb. sth. 把某物借给某人 sb be lent sth/ sth be lent to sb offer sb. sth. 将某物给某人 sb be offered sth/ sth be offered to sb pass sb. sth. 把某物递给某人 sb be passed sth/ sth be passed to sb ‎ pay sb. sth. 付给某人某物(钱)‎ sb be paid sth/ sth be paid to sb ‎ send sb. sth.把某物送给某人 sb be sent sth/ sth be sent to sb sell sb. sth.把某物卖给某人 sb be sold sth/ sth be sold to sb show sb. sth. 拿某物给某人看 sb be shown sth/ sth be shown to sb ‎ teach sb. sth. 教某人某物 sb be taught sth/ sth be taught to sb ‎ tell sb. sth.告诉某人某情况 sb be told sth/ sth be told to sb buy sb. sth. 为某人买某物 sb be bought sth/ sth be bought for sb ‎ make sb. sth.为某人制作某物 sb be made sth/ sth be made for sb ‎ ‎ ‎ 例1:同义句转换 My parents gives me a birthday present every year! (变被动语态,两种表达)‎ ‎____________________________________________________________________‎ ‎____________________________________________________________________‎ 解析:答案I am given a birthday present by my parents every year. A birthday present is given to me by my parents every year. 分别把宾语me和a birthday作为主语。‎ 例2:He told us a story.(变被动语态,两种表达)‎ ‎_____________________________________________________________________‎ ‎_____________________________________________________________________‎ 解析:答案We were told a story(by him)或A story was told to us by him.分别以we和a story 做主语,主语谓语动词的形式以及时态。‎ 知识点4:感官动词see,hear,watch,feel,notice及使役动词let, make, have等,动词后省略to不定式,变为被动语态时,应加上不定式符合to.‎ 例:I always see the boys play in the park. (变成被动语态)‎ ‎ The boys are always seen to play by me in the park.‎ 例1:He was made ___ a lot of work. ‎ ‎ A. do B. to do C. did D. doing ‎ 解析:答案B。make的用法是make sb do sth,在被动的情况下,需把省略的不定式to还原。所以被动形式为be made to do sth。‎ 例2:He was seen something from the shop . ‎ A. steal B. to steal C. to be stolen D. stealed ‎ 解析:答案B。see的用法,see sb do sth和see sb doing sth,被动态是sb be seen to do sth和sb be seen doing sth,所以根据选项来看,这里选择B。‎ 知识点5:一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。   ‎ 例:We can't laugh at him. →He can't be laughed at by us.‎ 例1:翻译 ‎1. 从来没有听说过这件事情。‎ ‎_______________________________________________________‎ ‎2. 我妹妹由奶奶照顾的很好。‎ ‎_______________________________________________________‎ 答案:1. Such a thing has never been heard of before. ‎ ‎ 2. My sister will be taken care of by Grandma. ‎ 例2:单选题 ‎1. I think much attention ____your pronunciation.‎ A. must be paid to   B. ought to paid to C. must pay to   D. should be paid ‎ 解析:答案A。首先attention作主语,后面需接被动语态,所以先排除B和C。又因为pay attention to这个动词短语,在被动语态时,后面的to不可以丢掉,所以选A。‎ ‎2. Our teacher ______ carefully. A. should be listened to B. should be listen C. be listened D. is listened 解析:答案A。首先our teacher作主语,后面表示“被听”,需接被动语态,又因为是单数,所以先排除C。又因为listen to这个动词短语,在被动语态时,后面的to不可以丢掉,所以选A。‎ ‎【课堂总结】‎ 我的收获:‎ ‎1、 ‎ ‎2、‎ 我的疑惑:‎ ‎1、‎ ‎2、‎ ‎【课后作业】‎ 一:选择题 ( )1._____ a new library _____ in our school last year? ‎ A.
