教师点拨语法特点并提醒重难点：一. 被动语态的形式是be done, 二. 现在完成时经常与Since, for, yet, already, so far, by now, in the past few years, how long等词连用，三. 助动词的选择have/has 要与主语一致。

设计说明：学生通过主动观察，发现，在教师的点拨下，较好地归纳出现在完成时被动态的结构，避免了以往教师上语法课喋喋不休的讲解，学生听得昏昏欲睡的被动局面。

I. Game:

Task: Describe what has happened in the pictures

2. Four groups are divided, and every group chooses one picture. The group which gives the most sentences will win. Because time is limited, the most sentences are six.
