牛津译林版英语八年级下册被动语态总结精讲及提高训练熟记结构被动语态的谓语结构：be +过去分词(P.P)（再次复习熟练过去分词）具体变化为：★一般现在时的被动语态：am/is/are +P.P★一般过去时的被动语态：was/were +P.P★一般将来时的被动语态：will/shall +be +P.P现在完成时的被动语态：have/has +been +P.P★含有情态动词的被动语态：情态动词can/may/must/should + be +PP.明确用法下列情况可判断用被动语态★物作主语常用被动语态e.g. Luckily his missing bike____was found_____(find) yesterday.★句子中出现by sb.e.g. Now a lot of work can___be done_____(do) by robots.★动宾搭配中，动词后面的宾语提前作了主语(如ask/tell/invite sb. to do等) He might___be caught____(catch) in the rain yesterday.In the old days, the workers___were made_____(make) to work 12 hours a day. Don't get out of the room until you___are told____(tell) to.★根据句意，需要用被动When you___are given___(give) something, you should say "Thank you."熟练转换主动语态变被动语态的方法，分三步走：★主动语态的宾语变成被动语态的主语；★谓语变成“be +PP."；★主语变成by后的宾语；(有时by短语可以省略)e.g. They make TV sets in that factory. (改为被动语态) （注意时态一致）→TV sets are made by them in that factory.注意特例★含双宾语的主动语态变成被动语态时，有两种方法：a)将间接宾语sb.变为主语，直接宾语保持不变；b)将直接宾语sth.变为主语，间接宾语用介词to或for引导。
被动语态讲解一、各种时态的被动语态一般现在时：am／is／are＋动词过去分词Cars are made by them。
一般过去时：was／were＋动词过去分词The MP3 was bought by my father。
一般将来时：will/shall/be going to be＋动词过去分词The bridge will be completed in ten days.现在完成时：have／has been＋动词过去分词The meeting has been put off。
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to的情态动词变成被动语态后“to”仍要保留。
歌诀是：情态动词变动，情态加be加“过分”.例如:we can repair this watch in two days. →This watch can be repaired in two days.We must finish this work soon。
→This work must be done soon.We have to clean the classroom。
→ The classroom has to be cleaned by us。
三、主动语态变被动语态需要注意的几个问题.（1)时态保持一致.I have repaired my computer。
-—-My computer has been repaired.（2）如果要说出动作的执行者，并且这个执行者可以作主动语态中主语时，就用by短语，如果后面的词表示地点，不是动作的执行者,就用in短语.It is made by us. It is made in Wuhan。
(3）主动句的主语是代词的主格形式，变成被动句by的宾语时要用其宾格形式.He cleaned the car. → The car was cleaned by him.(4）疑问句的被动语态，用be动词的对应形式代替doDoes she drive this car? →Is this car driven by her?（5）谓语为动词短语的被动语态不能丢掉动词短语的介词或副词。
8B Unit 7 the Passive Voice（被动语态）一．构成: be +done(及物动词的过去分词)二．不同时态的被动语态构成：1. 一般现在时：am / is / are+ done2. 一般过去时：was / were+ done3. 现在完成时：have / has+ been+ done4. 一般将来时：will / shall / be going to be+ done5. 现在进行时：am / is / are + being + done 5. 情态动词的被动语态：情态动词+be +done 三．被动语态的注意点1.只有及物动词才有被动语态，不及物动词没有被动语态。
如disappear(消失), come out（出版）,appear（出现），happen, take place, belong to, come t rue, break down 等通常不用被动语态。
如：An accident happened last night. The dog died two days ago.2.连系动词不用被动语态：look，seem，feel, sound, smell, taste / become, grow, get, turn如：The flowers smell sweet. The food tastes good. The music sounds wonderful.3.某些及物动词+副词用来表示事物的性质，不用被动：如：wash well, write well, sell well, wash easily, grow well, type easily, print quicklyThe women's clothes wash easily. This book sells well.4.使役动词make / let / have sb. do sth 与感官动词see，look at / hear, listen to / watch / notice (注意到) /feel sb. do sth.的结构，变成被动语态后do要变成to do。
被动语态 Passive voice 第一讲Part 2【被动语态】一、概念语态是动词的一种形式,表示的是主语和谓语之间的关系。
，英语动词有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。
Eg. ①They built a new bridge over the river. (主动) →A new bridge was built over the river by them. (被动)①Many people speak English. (主动) →English is spoken by many people. (被动)二、被动语态的基本用法被动语态由助动词be＋过去分词构成,时态通过动词be表现出来。
We use the active voice when it is important to know who performs the action.(1) it is obvious who performs the action动作的执行者是泛指或不言自明时：Eg. None of the books was taken away.(2)We do not know or don’t need to now who performs the action在不知道或没有必要知道动作的执行者是谁时：Eg. The toy is designed for children.(3) the action is more important than the person who performs the action需要强调动作的承受者Eg. Rice was first grown in China.【拓展】(4)出于礼貌或委婉而避谈动作的执行者。
Eg. This problem was talked about just now.(5) 在被动语态句子中,如果我们需要指出动作的执行者,可以由by引出。
