二、被动语态的构成 1、被动语态由“_____＋及物动词的______”构成。此时人称、数和时态的变化是通过____的变化表现出来的。一般疑问句直接将_____提前，否定句在______后加not. 2、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，原来带to的情态动词变成被动语态后“to”仍要保留。一般疑问句直接将_____提前，否定句在______后加not. 歌诀是情态动词变动，情态加be加“过分”， 例如We can repair this watch in two days.→This watch can be repaired in two days. 被动语态有各种时态的变化。
一般现在时___／___／____＋________ 一般过去时_____／_______＋_________ 一般将来时_____／__________＋_______ 现在进行时___／___／____ ______＋_____ 过去进行时_____／_____ _____＋_______ 现在完成时_____／____ _____＋_____ 歌诀是被动语态be字变，过去分词跟后面。
三、被动语态的用法 1_______或_____________动作的执行者是谁。
例如Some computers were stolen last night. 一些新电脑在昨晚被盗不知道电脑是谁偷的 2强调动作的_______，而不强调动作的_______。
例如the window was broken by Mike.窗户是迈克打破的。
歌诀谁做的动作不知道，说出谁做的没有必要；
动作承受者需强调，被动语态运用到。
四、主动语态变被动语态的方法 1把主动语态的_____变为被动语态的_____。
2把_____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_____放在介词_____之后作_____，将___格改为___格。若为产地则用介词_____例如All the people laughed at him.→He was laughed at by all people. 歌诀是宾变主，主变宾，by短语后面跟。
谓语动词变被动，be后“过分”来使用。
五、注意 1、一个句子能否改被动语态取决于谓语动词是否为_______动词；
2、被动语态的人称和时态均对______ 进行变化，结构中动词均用_____分词；
