主动语态如何变被动语态的口诀：

宾变主, 主变宾, by短语后面跟。

谓语动词变被动, be后“过分”来使用。

A Chinese scientist has already developed a pen-like computer. A pen-like computer has already been developed by a Chinese scientist. The earthquake has killed many people .

1. 副词的位置

often, usually, always, never, hardly, seldom等副词置于have/has和been中间。

[误]A big earthquake was happened in Wenchuan. 3

[正] A big earthquake happened in Wenchuan. 2. 并不是所有动词都有被动语态

本节课的总目标是让学生通过自主学习，自我探究，合作学习，完成归纳总结语法规律的任务，用问题引导学生，用问题驱动课堂，让学生在课堂上“动起来”，让课堂成为发展的课堂，生成的课堂。
