本节课的授课内容为被动语态中知识的总结梳理：总结学习被动语态的基本结构；学习被动语态与主动语态之间的变法；学习掌握各种时态的被动语态结构。对于该内容，基础好的学生掌握较好，但是仍然很难形成知识网络，基础差的学生半知半解，加上语法容易让人觉得枯燥，学生对此内容有排斥畏难心理。所以教学中将语法知识的传授和语言基本技能的学习结合到一起，注重学习语法与语言的运用。

V 教学方法

多媒体教学，任务型教学法。

VI 教学过程

Step 1 Revision复习引入（任务一）

1.语态概述：英语中动词有主动语态和被动语态两种语态. 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, 在被动语态中动作的执行者有时用by短语表示出来.

2.被动语态的用法：通过提问，让学生们回忆总结使用被动语态的七种情况。多媒体展示：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，当主语和谓语动词构成被动关系，即谓语动词是人的动作，但主语却不是动作的执行者，而是动作的承受者时，即需要用被动语态。汉语中常用“被”、“给”、“由”、“受”等词用来表示被动

Step 2 Presentation 语法呈现（任务二）

1.被动语态的谓语构成：助动词be＋动词过去分词(根据句子的主语和时态，助动词be的变化是通过人称、数和时态的变化表现出来的，疑问式和否定式的变化也如此。有am, is, are, was, were, been几种形式变化。)

2.主动语态和被动语态结构的转换：

多媒体展示例题:主动语态:We clean our classroom every day.

被动语态:Our classroom is cleaned by us every day.

根据例题来讲解主动语态变被动语态的方法：

(1)把主动语态的宾语变为被动语态的主语。

(2)把谓语变成被动结构(be＋动词的过去分词)(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)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。

[注意]①把主动语态改为被动语态时，句子的时态不能变。

　　　②如果主动句中的主语是人称代词，改为被动句时作介词by的宾语，要用宾格。如上例中的主语we改为us。

Step 3 PresentationⅠ（任务三）

1.利用多媒体展示各种常用时态的主动语态与被动语态之间的变化，师生共同总结出其被动语态的结构。（共9种被动语态的句子结构）

(1)一般现在时：am/is/are + v.过去分词

(2)一般过去时：was／were＋V.过去分词
