1、,被动语态专项讲练,.主动语态与被动语态：英语动词有两种语态,即主动语态(The Active Voice)与被动语态（The Passive Voice)。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。被动语态由be+过去分词构成，时态通过be表现出来。,主动语态,被动语态,主动语态,被动语态,e.g Many people speak English.,主动语态变被动语态的步骤：1、主动语态的宾语变为被动语态的主语；2、主动句的谓语动词变为被动结构；3、主动句的主语变为被动句的宾语，由by 引出，当不强调动作的执行者时，常省略。4.其它成分不变。,什么时候不加by 注意：

2、1)不知道谁是执行者eg:His new car was stolen.2)强调动作的承受者而不是执行者eg:The car was parked in front of this shop.3)礼貌及委婉语气eg:All the work must be finished before May.,各种句型的被动形式,肯定句 主语+be+过去分词+（by）否定句 主语+be not+过去分词+（by）一般疑问句 Be+主语+过去分词+(by)?特殊疑问句 疑问词+be+主语+过去分词+（by）？,注意：这里 be 的形式决定了被动语态的时态，其后的过去分词没有变化。,重点内容,所有时态的被动语

3、态否定就是在 最前面的助动词后加 notMany trees are being planted now.疑问就是把最前面的助动词提前。,Many trees are not being planted now,Are many trees being planted now?,变被动语态时需要注意的事项,一变二套三注意,宾变主，主变宾，宾语前面by跟，谓语动词变过分，不忘前面be动词跟,套时态，主被动时态一致,注意因人称的变化而引起的主谓一致问题。,1.They make shoes in that factory.主语+及物动词+宾语,Shoes are made(by them)in t

16、例：make sb do sth sb+be+made to do sth see sb do sth sb+be+seen to do sth A girl saw Tom fall off the tree.Tom was seen to fall off the tree by a girl.The boss made the workers work hard.?The workers were made to work hard.,一感 二听三让 四看,feel,listen to.hear,let.have.make,watch.see.look at.notice,eg.We o

17、ften see him play basketball.,He is often seen to play basketball by us.,The boss made the children work for long.,The children were made to work for long by the boss.,2.“双宾语”改被动语态，直接宾语(物)作主语，那么动词后要用介词.(这个介词是由与其搭配的动词决定)pass、bring、buy、show、send、give、cook等。把指“人”的间接宾语变主语，“物”不变。He gave me a book.变直接宾语加t

18、o.变间接宾语不加 I was given a book(by him).A book was given to me(by him).He showed me a ticket.I was shown a ticket(by him).A ticket was shown to me(by him).My father bought me a new bike.I was bought a new bike(by my father).A new bike was bought for me(by my father).,间接宾语,直接宾语,“主动”表“被动”常见的三种情况,（1）表示某物自

19、身内在特点，主动表示被动。常见：This pen writes well.The shirt washes well.This new book sells well.The door wont work.The shop opens/closes at 8:00 am.注意区别：The shirt is being washed now.汉译？,(2)有些词如want,need,require和 be worth后面，V-ing形式为主动，意义为被动。如：The room needs/wants/requires cleaning.=The room needs/wants/required

20、 to be cleand.The book is worth reading.,(3)句型“主语+be+形容词+to do”，“主语”是“不定式”的“逻辑宾语”，通常用不定式的主动形式表示被动含义。这类形容词有：easy，difficult，heavy，hard，nice，dangerous,light,interestingimportant，expensive，fit，comfortable，impossible等。The picture is pleasant to look at The chair is comfortable to sit on The work is impos

21、sible to finish.注意：当不定式中的动词是不及物动词时，要根据需要补充相应的介词。The pen is comfortable to write with.,三、注意动词短语的,常考到的动词短语有,完整性,take care of,look after,listen to,speak to,eg.1.We should speak to the old politely.,The old should be spoken to politely.,2.The nurse takes good care of the baby.,The baby is taken good car

22、e of by the nurse.,无被动语态的动词：不及物动词无被动happen,belong to,suit,fit(适合),come true、die,join,fall,last（延长）,cost,break out（爆发）appear,burst out(迸发)，hold(容纳)，lack（缺乏），agree with This room can hold 500 people.Taiwan belongs to China.The T-shirt fits me very well,and it only cost 20 yuan.SARS broke out in China

24、,get/have sth.done 含被动(找人做某事)十六岁的孩子不应该打耳洞。Sixteen-year-olds should not be allowed to get their ears pierced.I should get my shoes repaired.He should have his hair cut.Lets get the work done.,口诀1：宾提前变主，主变介by宾，被动be加done,时态看主动。口诀2：如 遇双宾语，最好变间宾，如若变直宾语后加to/for(pass,lend,buy,write,bring,show,tell)口诀3：有些动词

25、真奇怪，主动句中to 离开，被动句中to回 来。两听，两感觉，三做，四看He made me do the work.I was made to do the work by him.口诀4.含动词词组的被动语态，须将其看作一个整体，不可把它们分隔开来。They take good care of the baby.The baby is taken good care of by them,中考挑战,各种时态的被动结构练习,1、The Chinese food _ to be the healthiest in the world.A.considers B.is considering C
