被动语态复习教学设计教学目标:1.掌握各种时态的被动语态的结构2.能够正确的把主动语态变为被动语态3.掌握被动语态的各种特殊用法学情分析:本课是关于被动语态的复习,历来语法的讲解都是相当的枯燥和难以理解,再加上我班学生的英语学习情况两级分化严重。
所以本堂课主要以利用图片、做练习等内容来活跃课堂气氛,增加学习语法的趣味性,让大多数同学对英语学习感兴趣。
在这个阶段的学生对被动语态在感官输入上和语法体系上都不是很熟悉,而且主动语态的知识体系已经在学生的已有知识中比较完善。
所以本课的出发点要从主动态开始,并且要引导学生对两种语态进行必要的分析和对比,从而起到对被动语态知识进行巩固。
重点难点:被动语态的几种特殊用法学习方法:讲练结合,讲问结合教学过程:活动一:课前预习案活动二:课内探究案I 探究一:各种时态的被动语态的结构一般现在时 _________________________________________一般过去时 _________________________________________一般将来时 _________________________________________现在完成时 __________________________________________含有情态动词 __________________________________________II. 探究二:单项选择( )1.—Do you often clean your classroom?—Yes.
