一、教学内容分析

这是本单元的第四课时，先自主学习，后小组合作探究，教师重点点拨，小组总结评价。从小测单词拼写，英英猜词，习题巩固，到现在完成时的被动语态，翻译短句巩固提高，低起点，小台阶，以单元课文为基础；目的是复习巩固本单元重点单词和相关语法。

二、教学目标

1.知识与技能：复习本单元重点词汇和短语及其应用；掌握现在完成时的被动语态。

2.过程与方法：通过小组讨论交流和成果展示交流，达到能力共同提升。

3.情感、态度与价值观：通过小组学习，体验学习的乐趣。通过个人展示，增强学习的信心,体现自我价值。

4. 重点：解决学生在自主学习中本单元重点词汇和短语的练习难点。

5. 难点：现在完成时的被动语态在具体语言环境中的运用。

三、学习者特征分析

二中系列的学生，普遍英语基础薄弱。对于学好英语，大多数学生信心不足。对本单元经过几天的学习，学生了解了有关电脑的发展历程，及其在当今社会的广泛应用。同时，也积累了相关词汇；尤其是重点掌握了单词表中的黑体单词以及相关短语。对于重点词汇的学习，教师准备了学生自主学习的学案；利用一节课，学生先自主学习，后合作探究；第二节课，教师针对相关问题再重点点拨，巩固提高。这样，班内大部分学生掌握本单元学习的重点词汇。

八、教学反思

这是本单元的第四课时，学生先自主学习，后小组合作探究，教师重点点拨，小组总结评价。从小测单词拼写，英英猜词，习题巩固，到现在完成时的被动语态，翻译短句巩固提高，低起点，小台阶，以单元课文为基础；目的是复习巩固本单元重点单词和相关语法。

其中，小组代表展示，其他小组质疑的过程，总是精彩不断。学生代表，已经适应了小老师的角色。有些小老师，对简单的题，还会考考大家，效果很好。有的小老师还查字典，写例句，讲解很到位！

这节课，大部分学生都能跟得上，效果很好，同组教师也反映，课堂效果不错！同时也暴露出学生学习中的新问题。教师在以后的课堂教学中，还应该加强练习。

如果重新上这节课，我会鼓励学生在自主学习中，自己多查字典，学会自学。另外，多鼓励性格内向的学生，作为本组小老师，多参与展示！
