附：Thepassivevoice(供教师参考，建议逐步渗透)一、语态概述二、被动语态的构成三、被动语态的用法四、主动语态变被动语态的方法五．主动语态的注意事项英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。巧记为：主动、主动、主主动。被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。一、语态概述被动语态由“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一般现在时态中的构成。二、被动语态的构成口诀1：被动语态be字变，过去分词跟后面。一般现在时：am／is／are＋taught1、不知道或没有必要说明动作的执行者是谁。e.g.Somenewcomputerswerestolenlastnight.

一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)Thisbookwaspublishedin1981.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。e.g.Thewindowwasbroken

byMike.窗户是迈克打破的。

Thisbookwaswritten

byhim.这本书是他写的。三、被动语态的用法口诀2：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。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。例如：

Allthepeople

laughed

at

him.

He

waslaughed

at

byallthepeople.四、主动语态变被动语态的方法口诀3：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。

1.不及物动词和词组不用被动语态.Thatpendoesn’tbelongtoMary.2.及物动词词组在被动语态中不可丢掉的词组中的介词.Theblindboyshouldbetakengoodcareof.3.主动结构的主语变为介词by的宾语,组成介词短语,在被动结构中位于动词之后;但在动作执行者无须说明或不必强调时,by短语可省略.
