教学反思
通过本课教学，我有如下几点反思：
1. 以教材为模板结合课标，重新设计教学内容。在导入环节展示图片，让学生通过对比，选择有机苹果，激发学生兴趣，起到了很好的调动作用，从而顺利的导入课文。
2本课模型思路清晰，环环相扣：
（1）结合本节课的有机耕作主题，利用图片导入本节课内容。
（2）听课文听力，了解文章的主旨大意。
（3）精读课文，让学生了解化学耕种的危害、有机耕作的好处及方法。
（4）巩固训练，在阅读课文的基础上，完成一个小短文。
（5）写作复述，在前面阅读的基础上，让学生尽可能总结关于有机耕作的好处。
（6）学生的角色扮演，进一步提升本节课的主题。
（7）本节课总结升华：进一步意识到有机耕作的好处，提升宣传有机、绿色耕作的重要性。。
（8）作业。写一篇未来农业耕种的文章。
3. 以学生为中心，把课堂交给学生，让学生在学习中体验成功和快乐。新课改，更强调学生自主学习，主动学习，让他们动脑、动口、动手，训练他们听说读写的综合能力！
4、一节课下来，我也有一些遗憾的地方。
（1）我们班的学生有一部分英语基础相对薄弱，在阅读、做题、表达等反应方面不是很灵活，在完成任务方面，效率不高，致使课堂效果不是很活跃。
（2）.学生参与度不够
一部分同学因为口语较差，即使知道答案，因为无法用英语语言表达内心的观点以及看法，所以不敢回答，导致课堂不能做到人人有效参与，课堂上显得非常被动。对这部分基础差的学生多加鼓励，激励他们敢于开口讲英语，即使出现低级的表达错误，也要保护学生的自尊心。
