21、ing exercise P41,Ex 1&2Reflection after teaching（教学反思）本节课我通过不同的任务设置，让学生在小组活动中通过合作和探究来完成各个任务。新教材要求教师改变单纯进行语法教学的方式，将语言的形式与其意义、交际功能有机的结合起来，通过在实际的语言运用中内化语言规则，从而使学生达到能准确运用语言进行有效交际的目的。但是大多数学生离开课堂之后并没有多少听说英语的练习机会，他们十分缺少环境英语的反复刺激。导致学生的语言基础不扎实，在表达自己的看法和用英语进行讨论时，不时有学生夹杂着汉语，或有的学生不敢大胆说出自己的看法，欲言又止。所以在学生进行小组活动时，应尽量给学生更多的帮助，主动了解学生的语言困难。总之, 学生在有限的课堂中学到的知识毕竟有限，我们要让他们掌握语言的同时，将课堂学到的知识内化为能力，继而实现语言学习并运用的目的。同时，运用写作引导学生体验语言的用法，提升学生的能力。
