教 学 过 程
StepⅠWarming up
让学生写出六种时态的被动式结构
StepⅡ.复习内容
1、概述:语态表示主语和谓语动词之间的关系。英语有两种语态,即主动语态和被动语态。
主动语态:表示主语是动作的执行者。 被动语态:表示主语是动作的承受者。
如: Many students study English. (主动语态)
English is studied by many students. (被动语态)
2、构成:be + 动词的过去分词
3、用法:
1)不知道或没有必要说明动作的执行者是谁。Such books are written for children.
2)强调动作的承受者,这时应用by短语。The cup was broken by David.
4、时态:主动语态有不同的时态,被动语态也有不同的时态。被动语态的不同时态主要体现在“be + 动词的过去分词”的be上。

含有情态动词的句型
情态动词+ be + 动词的过去分词
主动语态变被动语态口诀:
一变:宾变主,主变宾,宾语前面by跟,谓语动词变过分,不忘前面be动词跟
二套:套时态,主被动时态一致
三注意:注意因人称的变化而引起的主谓一致问题。
