将所学知识与实践结合起来，学以致用，既巩固提高了英语，又为环保贡献了力量，何乐而不为呢？
教学反思：
本节课以“环境保护”为话题，以“谈论污染和环保”为交际功能。由于话题是社会生活中的热点，所以学生易于参与和讨论。其中用到了现在进行时、一般过去时、含情态动词的句子以及被动语态等结构，这是对以前所学语法知识的复习应用。
本节课前，我从歌曲引课、情景创设、课件设计，学生积极性的调动等方面都做了充分准备。在课堂教学中，我将启发式、讨论式、直观式、任务式，竞争式等多种教学方式融为一体。学生学习兴趣浓，参与率高，课堂气氛极为活跃。
总之，整个教学过程，不但加强了学生听说读写各方面的能力，又充分调动了他们学习英语的积极性，创造性和主动性。
我认为，英语课堂就是学生表演的舞台，而教师必须是优秀的导演，才能在这美丽的舞台上导出一幕幕精彩的剧情。
虽然上完本节课后我整体感觉良好，但仍存在很多不足，如引课的歌曲最好用英文版本，与学生的对话中对本节课复习的语法结构应用较少等。在以后的教学中，我将进一步去探索完善教学设计，力争做得更好。
