1、 点亮智慧人生被动语态复习 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（pp）”。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：amisarepp一般过去时：waswerepp一般将来时：shall will be pp现在完成时：have has been pp现在进行时：amisarebeingpp过去将来时：should would be pp含情态动词的被动结构：情态动词bepp例如： Chinese _ by the largest number of peopleAspeak Bis speaking Csp
2、eaks Dis spoken The boy _ to get supper ready after schoolAwere told Bis telling Cwas told Dtells A lot of new roads _ built in the west of ChinaAmust Bmust be Chas DhaveB明确用法被动语态常用于以下两种情况：1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；2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
3、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 onceThe broken pottery _ _ _ _ at once（同义句） Where did they grow vegetables? （改为被动语态）Where _ vege
4、tables _?D注意特例将主动语态变被动语态应注意几个特殊情况：1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）We 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 mother2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
5、副词不能省去。例如： This dictionary mustnt _ from the libraryAtake away Btaken away Care taken away Dbe taken away She will take good care of the children（变被动语态）The children will _ _ _ _ _ （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
6、Lake yesterday（变被动）He _ _ _ swim in Qianling Lake yesterday4不定式的被动结构：动词不定式的被动语态为“to be 过去分词”。例如：The radio says a wild animal zoo is to _ in our cityAbe building Bbuild Cbe built Dbuilt5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） By whom has the cup been
7、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 broken 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修饰，而需用much，very much，so much，too much修饰。试比较：He was very interested in sci
8、ence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一惊，不知所措。（被动语态）F牢记（相关）句型初中教材中与被动语态相关的句型有：1be covered with被覆盖2be made of由制作（发生物理变化） be made from由制作（发生化学变化）be made in由（某地）制造 be made by被（某人）制造3be used for被用来 be used as被当作（作为）来使用 be used to do sth被用来做某事4It i
