被动语态 教学 目标 ‎1、掌握主动语态与被动语态的区别 ‎ ‎2、熟练掌握被动式的构成 重点 难点 熟练运用不同时态的被动语态 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。‎ 时态 被动语态结构 一般现在时 am / is / are + 动词的过去分词 一般过去时 were / was + 动词的过去分词 现在进行时 am / is / are being + 动词的过去分词 过去进行时 were / was being + 动词的过去分词 一般将来时 ‎ will be + 动词的过去分词 过去将来时 would be + 动词的过去分词 现在完成时 have / has been + 动词的过去分词 过去完成时 had been + 动词的过去分词 3‎ 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。‎ Step Ⅲ Summary总结这节课复习到的知识 ‎【温馨提示】在小组内说一说自己在这节课上的收获。可以从词汇、句型、语法三方面来说 Step Ⅳ Class test 一、用适当的形式填空 ‎1.
