被动语态-副本

1、被动语态的含义英语中时态很多，但语态不多，只有两种，即：主动语态和被动语态。所谓被动语态：相当于中文中常说的 被”、生”的句式，如：他的自行车被偷了。：这座楼房是由他们建造的。”被动语态的结构那么，英语中被动语态是怎么样构成的呢？请看下面的例句（注意划线部分）：His bicycle was stolen.The building has been built in 2000.通过上面的例句，可以看出，被动语态”的构成是：be +过去分词+ （by+动作执行者）被动语态的运用什么情况下要用被动语态呢？ 一般地说，有下面几种情况： （1）不知道谁是动作的执行者或没有必要。例如：Paper is

2、made from wood.（纸是由木材生产出来的。）The house is quite old. It was built in 1950.（这座房子太旧了。它是 1950 年建成的。）He was wounded in the fight.（他在战斗在受伤了。）Electricity is used to run machines.（电是用来开动机器的。）（2）需要强调动作的对象时。例如：Calculator cant be used in the maths exam.（计算器不能用于数学考试。）Books and newspapers in the reading room mus

3、tnt be taken away.（阅览室的书籍和报纸不准带走。）He was awarded first prize in that contest.（他在比赛中获得了第一。）（3）为了使语气婉转，避免提到是谁做的这件事。例如：The construction of the new lab must be completed by the end of next month.（新实验室必须在下个月底前完工。）四各种时态的被动语态举例一般地讲，被动语态可用于英语的各种时态。为了能准确地运用被动语态，重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下：一般现在时的被动语态.am /

4、 is / are + 动词的过去分词Our classroom is cleaned every day.This car is made in China.2、一般过去式的被动语态：was / were + 动词的过去分词His desk was cleaned just now.The station was built in 1928.3、现在进行时的被动语态：am / is / are + being +动词的过去分词A new factory is being built in our city now.Some trees are being cut down in the pa

8、is.如何将主动语态变成被动语态1、从句子意义上说，就是重新找出什么事物”是 被完成”的。例1.主动语态： 人们说英语。People speak English in many countries.被动语态： 英语被说。English is spoken in many countries.例2.主动语态：我伞造这座桥。We built this bridge last year.被动语态：这座桥被建造。This bridge was built last year.2、从语法的角度说，把原句的宾语改成主语。例1.主动语态：小王邀请你（宾语）Xiao Liu has invited you t

9、o a lunch party. 被动语态：你（宾语）被邀t#。 You has been invited to a lunch party by Xiao Wang.例2.主动语态： 你不准带走杂志 （宾语）You must not take these magazines out of the reading-room.被动语态： 杂志（宾语）不准被带走.These magazines must not be taken out of the reading room.例3.主动语态：他们授给他（宾语）一枚奖章（宾语）.They gave him a medal for his wonde

10、rful work.被动语态：他（宾语）被授予一枚奖章.He was given a medal for his wonderful work.被动语态：一枚奖章（宾语）被授给了他.A medal was given to him for his wonderful work.六被动语态复习要点A.熟记结构被动语态的结构为 助动词be +及物动词的过去分词（p. p）”。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。其具体变化为：一般现在时：am/is/are+p. p.一般过去时： was/were + p. p .一般将来时：shall /will be

11、+ p. p .现在完成时： have /has been +p. p.现在进行时： am/is/are+being + p. p.过去将来时：should /would be +p. p.含情态动词的被动结构：情态动词+be+p. p.例如： Chinese by the largest number of people .speakis speakingspeaksis spoken（ The boy to get supper ready after school .were toldis tellingwas toldtells A lot of new roads built in

12、the west of China .mustmust behashaveB.明确用法被动语态常用于以下两种情况：.不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者；.强调动作的承受者。例如：这棵树是那个男孩弄断的。The tree by that boyC.熟练转换.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）。.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

13、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 .The broken potteryat once .（同义句）（ Where did they grow vegetables ?（改为被动语态）Where vegetables ?D.注意特例将主动语态变被动语态应注意几个特殊情况：.含双宾语的主动结构变为被动结构时，有两种方法：将间接宾语变为主语，直接宾语保持不变；将直接宾语变为主语，间接宾语用介词to或for引导。例如：He told us a story .（变被动语态）f We

14、 were told a story （by him）. 或： A story was told to us by him . Her mother gave her a new pen .（变被动语态）A new pen her by her mother .短语动词的被动语态：在变为被动语态时，要将短语动词视为一个整体，其后的介词或副词不能 省去。例如： This dictionary mustnt from the library .take awaytaken awayare taken awaybe taken away She will take good care of the

15、children .（变被动语态）The children w川（by her）.（3.含有复合宾语的主动结构变被动结构时，通常将宾语变为被动句的主语，而宾语补足语就成为主语补足语。注意：省略to的不定式作宾补时，不定式符号to必须补上。例如：Someone saw him swim in Qianling Lake yesterday .（变被动He swim in Qianling Lake yesterday .（4.不定式的被动结构：动词不定式的被动语态为“t（be +过去分词”。例如：The radio says a wild animal zoo is to in our city

16、 .be buildingbuildbe builtbuilt5.以疑问代词开头的疑问句转换成被动句时要注意词序：应将主动句中的疑问代词改为介词by的宾语，但仍然放在句子开头。例如：Who has broken the cup ?（改为被动语态）fBy whom has the cup been broken ?E.注意区别被动语态和过去分词作表语的区别：1）含义不同：被动语态强调动作，重点说明动作由谁完成、怎样完成；而过去分词作表语通常用来描写情景，叙述人或事物的特征及所处的状态。试比较：The window is broken .窗子破了。（系表结构）The window is broke

17、n by him .窗子被他打破了。（被动语态）2）用法不同：过去分词作表语时可以被so, very , too等程度副词修饰，而被动语态则不能用 so,very , too 彳慎饰，而需用 much , very much , so much , too much 彳修饰。试比较：He was very interested in science .他对科学有极大兴趣。（系表结构）I was so much surprised at the scene that I didnt know what to do .我被那种场面搞得大吃惊，不知所措。（被动语态）F.牢记（相关）句型初中教材中与被
