I eat an apple. What’s wrong with this apple now 正如汉语中的被字句,英语中的“被字句”我们称之为被动语态。英语中有两种语态: 。英语的语态是通过 表现出来的。 主动语态表示主语是动作的执行者。巧记为:主动、主动、主去动。 例:Many people speak English. 谓语:speak的动作是由主语many people来执行的。 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 被动语态表示主语是动作的承受者,即行为动作的对象。 例如:English is spoken by many people. 主语English是动词speak的承受者。 一、被动语态的构成 “be+及物动词的过去分词”构成。不及物动词本身没有被动语态。 及物动词vt..--- 本身意义不完整,后必须带宾语,有些还可以带双宾。 不及物动词v.i.---本身意义完整,不需要带宾语,如带宾语必须通过介词。 人称、数和时态的变化是通过be的变化表现出来的。 被动语态在各种时态中的构成。 1) am/is/are +done (过去分词) 一般现在时 例 . 参观者请勿触摸展品。 2) has /have been done 现在完成时 例 任务的所有准备工作已经完成,我们准备开始。 3) am/is /are being done 现在进行时 例 这里正在建造一座新电影院。 4) was/were done 一般过去时 例 我有十分钟的时间来决定是否拒绝这一提议。 5) had been done 过去完成时 例 到去年年底,北京的另一个新公园已经完成了。 6) was/were being done 过去进行时 例 会议举行时我在那里。 7) shall/will be done 一般将来时 例 如果工厂关闭,几百份工作就会没了。 8) should/would be done 过去将来时 例 只要消息一到,就会直接被送达士兵的母亲那边。 歌诀是:被动语态be字变,过去分词跟后面。 二、被动语态的用法 (1)不知道或没有必要说明动作的执行者是谁 例: 一些新电脑在昨晚被盗了。 .这本书出版于1981年。 (2)强调动作的承受者,而不强调动作的执行者。 例: 窗户是迈克打破的。 这本书是他写的。 (3) 为了更好地安排句子 例The well-known person got on the bus and was immediately recognized by people. (4)It is said that+从句及其他类似句型 一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It+be+过去分词+that从句”或“主语+be+过去分词+to do sth.”。有: It is said that… 据说,It is reported that…据报道,It is believed that…大家相信, It is hoped that…大家希望,It is well known that…众所周知, It is thought that…大家认为,It is suggested that…据建议。 例 据说这个男孩已经通过了国考。 三、主动语态变 被动语态的方法 (1)把主动语态的宾语变为被动语态的主语。 (2)把谓语变成被动结构(be+过去分词) (根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式)。 (3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。例: All the people laughed at him. ---- They make the bikes in the factory. ---- 被动语态的特殊结构形式 1)带情态动词的被动结构。其形式为:情态动词+be+过去分词。 例The baby should be taken good care of by the baby-sitter. 2) 有些动词可以有两个宾语,在用于被动结构时,可以把主动结构中的第二个宾语变为主语,第一个宾语仍然保留在谓语后面。 例His mother gave him a present for his birthday. 可改为 3) 当“动词+宾语+宾语补足语”结构变为被动语态时,将宾语变为被动结构中的主语,其余不动。 例Someone caught the boy smoking a cigarette. 可改为 4)在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时,在主动结构中不定式to要省略,但变为被动结构时,这些词的后面要加to。 例Someone saw a stranger walk into the building. 可改为 5) 有些相当于及物动词的动词词组,如“动词+介词”,“动词+副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开。其中的介词或副词也不能省略。 例The meeting is to be put off till Friday. 四、主动形式表示被动意义 1.英语中有很多动词如 break,catch,clean,drive,lock,open,sell,read,write,wash等,当它们被用作不及物动词来描述主语(主语通常是物)特征时,常用其主动形式 表达被动意义。 例 This kind of cloth washes well. 注意:主动语态表被动强调的是主语的特征,而被动语态则强调外界作用造成的影响。 试比较:The door won't lock. The door won't be locked. 2. 表示“发生、进行”的不及物动词和短语,如:happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。 例 How do the newspapers come out 这些报纸是如何引出来的呢 3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。 中考英语语法知识点之主动语态与被动语态的区别 在主动语态中,主语后面接人(be +动词原型) 主语是谓语动词的使动方 被动语态(be+动词过去分词) 主语是谓语动词的受动方 例:主动语态:We use electricity to run machines. 被动语态: 中考英语考点 之 主动形式表示被动意义 大家都知道,用被动语态(形式)来表达被动意义,但有些句子用的却是主动形式,表达的却是被动意义。下面我们就来总结一下常见的用主动形式表示被动意义的几种形式。 1.连系动词(如:feel,taste,sound,smell,look等)用主动形式表示被动意义。如: This material feels very soft. 这块材料摸上去很柔软。 这个苹果尝起来很好吃。 2. 有些表示主语内在性质或性能的不及物动词常与一些副词连用,用一般现在时的主动形式表示被动意义,其主语一般为事物。这些动词有:sell,read, write,wash,wear,last等。如: The pen writes smoothly 这支笔写起来很流畅。 这种食物很畅销。 3. 动词need, want, require表示"需要时",后接动名词或不定式的被动式表示被动意义。如: Your room needs cleaning/to be cleaned. 你的房间需要打扫一下。 我的房子需要修理一下。 4. 在"be worth doing"短语中,动作与主语之间存在动宾关系,用主动形式表示被动意义。如: 这本书很值得一读。 5. 在"主语 +be + adj +to do"这个句型中,不定式动作与主语之间存在动宾关系,则用主动形式表示被动意义。如: This question is hard to answer. 这个问题很难回答。 英语很好学。 6. Won't或wouldn't表示"不愿"时,后面的动词常用主动形式表示被动意义。如: The door won't open. 这门就是打不开。 这个盒子就是移不动。 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 主动语态改为被动语态 We often use a recorder(录音机) in our English class. 二、 选择填空 1.
