中考英语专项复习-被动语态主备人:徐敏【教学目标】1. 掌握被动语态的用法;2. 掌握如何将主动语态变成被动语态;3. 掌握变被动语态时须注意哪些问题。【教学过程】一、英语的两大语态:主动语态和被动语态A.主动语态中主语是谓语动词的发出者(即动作的执行者)。宾语是谓语动词的对象(即动作的承受者)。B.被动语态中主语是谓语动词的承受者(动作的对象)。二、被动语态的谓语构成:助动词be动词过去分词被动语态的不同时态是通过be的时态变化来表示的,其人称和数方面应与主语保持一致。各种时态的主动语态和被动语态谓语结构对照表:重点考查一般现在时、一般过去时、现在完成时及含情态动词的被动语态。动词不定式的被动语态为“to be 过去分词”。need +v-ing意为“需要被.”,相当于need to be 过去分词。( ) The radio says a wild animal zoo is to _ in our city Abe building Bbuild Cbe built Dbuilt( ) -Jim, the floor is so dirty. It needs _. -OK, Mom, Ill do it now. A. to sweep B. cleaning C. cleaned D. be swept三、什么时候要用被动语态呢?在下列三种情况之一要用被动语态:不知道动作的执行者是谁,用被动语态。没有必要指出谁是动作的执行者,用被动语态。需要强调动作的承受者时,用被动语态。四、掌握如何将主动语态变成被动语态?1. 将主动语态变被动语态的基本方法为: 将主动语态的宾语作被动语态的主语; 谓语动词变为“be及物动词的过去分词”,并通过be的变化来表达出不同的时态; 主动语态的主语变为介词by的宾语,组成介词短语放在被动结构中的谓语动词之后。(有时by短语可以省略)。 2被动语态的一般疑问句是将一个助动词置于主语之前;否定句是在第一个助动词后加not;特殊疑问句的语序为:疑问词一般疑问句。例如: You must throw the broken pottery away at once(同义句) The broken pottery _ _ _ _ at once Where did they grow vegetables?(改为被动语态)Where _ vegetables _ ?Many people speak English. (改为被动语态)English _ _ by many people.He washed his shoes yesterday. (改为被动语态)His shoes _ _by him yesterday.五、在被动语态中要注意的问题:(一) 一些使役动词(let, have, make等)或感官动词(see, hear,watch,notice等)在主动语态中后面接的动词不定式不带to,但改为被动语态时,一定带to。如:A. The boss makes the workers work 18 hours a day. (变被动语态) The workers _ 18 hours a day by the boss.B. I saw him enter the house. (变被动语态) He _the house by me.C. The teacher let them leave the classroom after class. (变被动语态) They _ the classroom by the teacher after class. 【注意】当使用see/hear/watch sb. do sth.时,变为被动语态时,do 前要带to。而当使用see/hear/watch sb. doing sth.时,变为被动语态时,doing保持不变。如:1. We hear her sing in the room every day.(变被动语态) She _ in the room every day.2. I saw him going into the shop.(主动语态) He _ into the shop.(被动语态) (二)含双宾语的动词在变为被动语态时,可将指人的间接宾语提前做被动语态的主语;也可把后面指物的直接宾语提前做主语,但此时要在间接宾语前加上介词to或for。(主动语态)give/pass/bring/write/tell/show sth. to sb.(被动语态)sth. be given/pass/brought/written/told/shown to sb. 或sb. be given/pass/brought/written/told/shown sth.(主动语态)buy/make/get/cook sth. for sb.(被动语态)sth. be bought/made/got/cooked for sb. 或sb. be bought/made/got/cooked sth.汉译英:去年我过生日时姐姐给了我一块手表。(1) My sister _ for my birthday last year.(2) A watch _ by my sister for my birthday last year.(3) I _ by my sister for my birthday last year.(三)在主动语态中某些谓语动词是短语动词,要将短语动词视为一个整体,变为被动语态时我们不能丢掉其后的介词或副词。 汉译英:我们国家把老人照顾得很好。Old people _ in our country.(4) 谓语动词的主动形式表示被动意义:1. 有些不及物动词和短语无被动语态,用主动语态表达被动的意思。如:happen, take place, come true, come out, last, run out(用完)等。翻译句子:(1)这几年,我们家乡发生了巨大的变化。Great changes _ in my hometown over the years. (2)吉姆昨天发生了车祸。_(3)如果你努力的话,你会实现梦想的。If you work hard, your dream will _.(4)他的新书上个月出版了。 His new book_.2.少数动词后面有副词well 的时候也不用被动语态 。 ( 如:write well , wash well , sell well , grow well )系动词也不用于被动语态。(如:look看起来,sound听起来,feel摸起来,smell闻起来,taste尝起来) (1). This pen _. 这支笔好写。 (2). The jeans_ . 这条牛仔裤好洗。 (3). The apples _ and _ . 这些苹果闻起来很香,卖得好/好卖。 (4). Everything _ in spring.春季万物都生长得很好。注意:open 与 close汉译英:这家商店早晨八点开始营业,晚上十点停止营业。The shop _ at 8 oclock a.m. and _ at ten p.m. 注意辨析:1. be used to do sth.被用来做某事(被动语态)(=be used for doing sth.) use sth. to do sth.用某物做某事(主动语态)2.used to do sth.过去常常做某事3.be / get used to doing sth.习惯做某事【巩固运用】 1. 她过去常常在晚饭后沿这条马路散步,但是现在她习惯在家看电视。(汉译英)She _ the road after supper. But now she _ at home after supper.2.这把刀可以用来削苹果。(汉译英)The knife _ apples. (五)注意下列常见短语或句型:1. get / have sth. +过去分词 “使某事物被.”汉译英:(1).不应该允许16岁的青少年扎耳洞。Sixteen-year-olds shouldnt _ get their ears _.(2).我昨天理发了。I have my hair _ yesterday. 2. be allowed to do sth. 被允许做某事3. be regarded as .被视为.4. be covered with sth. 被.覆盖5. be filled with sth.装满/充满.6. be made of sth.由制成(发生物理变化) be made from sth.由制成(发生化学变化)7.
