同时也使得小组活动不流于形式，真正使每位学生参与交流与合作。


课后反思：
1．感觉课堂教学中较难掌握的是游戏这一环节，学生情绪之兴奋，思维之活跃< br>大大超出我的意料，一副看似简单的图片，却能讲出很多不同的句子，而且学生
强烈要求延长时间 ，多给他们造句的机会。虽然这能增加学生体验现在完成时被

动语态的机会，但在时间的 把握上存在一个问题，在最后设计的任务活动中，觉
得有匆匆过场的嫌疑。教学中，如何把握游戏这一关 ，还值得探讨。

2．学生不管是对现在完成时被动语态的操练还是应用，都出现了一些 问题，
如主谓不一致，忘记用过去分词或错用过去分词等，还有的学生不注意及物动词
和不及物 动词的用法，或根本不知道。
