8、nglish. 很多人说英语;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担者,即行为动作的对象;巧记为:被动、被动、主 被动;e.g.English is spoken by many people. 英语被很多人说;主语 English 是动词 speak 的承担者;主动态和被动态指的是动词形式,是词法概念;而主动句和被动句就指的是句子结构,从而是句法概念;所谓主动句就是由主动态动词(词组)作谓语动词的句子,而被 动句就是由被动态动词(词组)作谓语动词的句子;e.g.He opened the door. 他开了门;(主动句)The doo
9、r was opened. 门被打开了;(被动句)2被动语态的构成被动语态由“ 助动词be及物动词的过去分词” 构成;人称、数和时态的变化是通过 be 的变化表现出来的;现以 teach 为例说明被动语态在几种常见时态中的构成;一般现在时: amis aretaught 名师归纳总结 - - - - - - -第 3 页,共 12 页精选学习资料 - - - - - - - - - 学习必备 欢迎下载一般过去时: wasweretaught 一般将来时: will shall betaught 现在进行时: amis are beingtaught 过去进行时: was/were being
10、taught 现在完成时: havehas beentaught 歌诀是:被动语态 be 字变,过去分词跟后面;3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;e.g.Some new computers were stolen last night. 是谁偷的)一些新电脑在昨晚被盗了; (不知道电脑This book was published in 1981.这本书出版于 1981 年;(2)强调动作的承担者,而不强调动作的执行者;e.g.The window was broken by Mike.窗户是迈克打破的;This book was written by him. 这
11、本书是他写的;歌诀:谁做的动作不知道,说出谁做的没有必要;动作承担者需强调,被动语态运用到;4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)(依据被动语态句子里的主语的人称和数,be 的形式);以及原先主动语态句子中动词的时态来打算(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;e.g.All the people laughed at him. 全部的人都嘲笑他;He was laughed at by all the people. They make the bikes in the factory. 他们在
12、工厂里生产自行车;The bikes are made by them in the factory. 名师归纳总结 - - - - - - -第 4 页,共 12 页精选学习资料 - - - - - - - - - 歌诀是:宾变主,主变宾,学习必备欢迎下载by 短语后面跟;谓语动词变被动,be 后“ 过分” 来使用;5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,原先带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” ,原先带 to 要保留;e.g.We can repair this watch i
13、n two days.This watch can be repaired in two days. You ought to take it away.It ought to be taken away. They should do it at once.It should be done at once. 三、构词法1复合词英语中构成新词的方法很多,其中之一就是将两个独立的单词合在一起;我们把这种构词法称为“ 合成词构词法”;其实,我们目前已经学过很多通过合成方式构成的单词,如 classmate,homework ,basketball,football 等等;另外,合成词构词法是一种
14、十分活跃的构词方式,比如依据classmate 很多同学都会联想到roommate ,schoolmate,workmate ,playmate 等;合成的方式很多,常见的有:(1)名词 +名词:一般来讲,构成的词仍是名词,e.g.website, homework ,basketball (2)副词 +名词:可以构成形容词或副词,e.g.upstairs,downstairs 都既可作形容词,也可以作副词(3)副词 +动词:一般用来构成动词,e.g.download (4)名词 +形容词:构成形容词,2前缀、后缀构词法e.g.world famous,homesick想家的 加前、后缀是英语
15、中最常见的扩充词汇的方式,也是学习英语必需把握的构词法;比如,我们学会care,就能把握careful,careless,carefully, carelessly;下面我们介绍几个常见的前、后缀;(1) re-表示“ 再” ,如: rewrite ,reuse,recycle (2) inm-表示“ 无,不” ,如: incorrect, impossible,impolite 名师归纳总结 - - - - - - -第 5 页,共 12 页精选学习资料 - - - - - - - - - 学习必备 欢迎下载(3) un-表示“ 不,无”(4) dis-表示“ 不,无”,如: untrue
16、,unhealthy ,uncomfortable ,如: dishonest,disagree,disappear,dislike (5) anti-表示“ 反对,防止”,如: anti-pollution ,anti-war 反战 (6) -able 表示“ 可能,易于,适合于”,构成形容词,如:renewable,eatable可吃的 ,lovable可爱的 ,comfortable ,movable可移动的 (7)-ful 表示“ 布满 的, 具有 性质的”powerful ,useful,careful,beautiful ,构成形容词, 如:helpful ,hopeful ,(
17、8)-less 与-ful 相反,表示“ 少的, 不足的” ,构成形容词, 如:helpless,hopeless,powerless,useless,careless 四、定语从句1定语从句的概念在复合句中, 修饰某一名词或代词的从句叫定语从句;被修饰的名词或代词叫先行 词,定语从句一般放在先行词的后面;2定语从句的关系词引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that ,which,who(宾格 whom,全部格 whose)等,关系副词包括where, when, why 等;关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分;本 册书主
