被动语态教学设计被动语态教学设计 教学内容：被动语态 教学目标： 1.知识与技能：通过总结语法被动语态，让学生明确被动语态所要求掌 握和理解的内容。 2.过程与方法：通过想、听、说、练等手段，掌握被动语态的构成，并 能准确运用。 3.情感、态度与价值观：通过学生积极参与被动语态练习的过程，培养学 生换位思考的能力。 教学重点：学习被动语态的构成以及用法。 教学难点：被动语态的用法。 教学方法：参与式教学法。 教学过程： 一、热身：播放英文歌，讨论一下起热身作用。 二、值日生汇报，在她的汇报中复习初中所学的八种英语时态，并导入被动语 态。 各种主动语态变为被动语态的方法，并加以练习和总结。 三、 1. 先请同学们讨论，对被动语态进行归纳总结 主语与动词的关系：主动语态主语是动作的执行者，被动语态主语是动 作的承受者。 被动语态的基本结构：be + done（动词的过去分词） 一般现在时态的被动结构：am /is /are + done 一般过去时态的被动结构：was /were + done 一般将来时态的别动结构：will be + done 情态动词的被动结构：情态动词+ be + done （要求学生一定要记住这些 结构） 2 被动语态的用法： 我们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时， 或者只需要强调动作的承受者时，要用被动语态。 三、例题解析：（结合习题，教师给学生讲解如何分析并解决问题） 四、课堂练习： 学生完成课堂练习，先个体完成，然后核对检查，最后教师讲解 五拓展练习 . am/is/are+doing have/has+p.p. was/were +doing Hello, everyone!
