课后反思：在本节课一开始，展示图片，让学生先复习了sectionA的重要词汇，为后面的对话练习打下好的基础，用图片展示课文中的形容词及副词，提高了学生学习的兴趣，为知识的掌握奠定基础。本课为语法课，重点讲解形容词及副词的比较级。在讲课过程中，重视学生的合作探究能力，引导学生观察、发现、归纳和掌握语言规律，形成有效的学习策略。最后，通过多层次练习，让学生掌握核心语法知识。
亮点：
用图片回顾重点词汇，形象直观，提高了学生学习的兴趣，与此同时，利用图片，锻炼学生的对话能力。在讲语法知识时，重视学生的主体作用，通过小组合作，学生自己归纳语言规律。
不足之处：语法知识内容较多，课堂内容大，学生不易理解。
使用建议：
如果时间允许，可以多层次多角度的练习，加深学生的理解，更好地融会贯通。
