教材分析
本节课的教学内容是九Unit 8 We’re trying to save the earth(3a---self check)以及单元复习。其语言目标是：Talk about pollution and environmental protection，让学生认识环境问题及谈论如何保护环境。重点在这些语境中复习一般过去时、现在进行时、现在完成时和被动语态等。同时这也是本课的一大难点。本单元选取了与教材、生活实际都密切相关的问题进行探究，从而让学生分辨是非，增强他们的环保意识，让学生受到良好的思想教育。同时，教师采用任务型教学途径，竭力为学生创设接近实际生活的各种语境，通过一系列的生动有效的学习任务，进一步提高学生听、说、读、写的综合素质和技能，使学生最终达到“学以致用”。
课后反思
在本节课中，本人强化了基础知识的学习并注重培养学生们的的学习兴趣。通过鼓励性评价等措施，在教学活动中，尽量让学生们参与到活动中来，创造更多的机会，鼓励学生大胆地使用英语，树立学好英语的自信心。通过全体学生间的合作学习，降低他们的学习难度，使他们每一个人都能够体验到成功的喜悦，从而提高学生的综合语言技能。
课程设计较合理,给学生创设自主学习和交流的机会。整节课的主线是针对环境问题的what-why-how，学生通过体验、实践、讨论、合作等方式完成课堂过程并且发展了听说读写的综合语言技能。
导入部分 用动物自杀的视频导入，能激发学生的兴趣，同时引起保护环境的共鸣。
what环节，主要是进行听力训练，将课本中的听力以及课文进行改编。既提高学生的听力，又对课本知识进行巩固复习。
why环节，主要是小组合作，找出环境问题出现的原因。对课本知识进一步复习，同时学生在合作过程中，结合实际生活，使知识得到升华。
how环节 出示阅读部分的三个人物，引导学生回顾他们对环保的贡献；然后引导学生说出我们在日常生活中可以做得环保点滴，并通过小组合作找出针对不同污染的措施。
survey 该部分是对课堂所学的学以致用，讨论身边的环境问题，为下步写作做下铺垫。
writing该部分是对课堂内容的升华。本课一大亮点在写作之前给出相应指导，而且不是单纯的给出思路。，在写作之前将self-check部分的词性变化以及时态语态练习，作为写作指导出示，大大降低学生写作的难度。
但是，教学过程中，也存在不足之处：
1. 课堂的感染力不够，未能更好的调动学生的积极性。
2. 课程内容较多，容量较大。所以时间比较紧迫，写作环节未能让学生得到充分展示。
3. 对后进生的帮助不够。应该尽可能地给后进生提供更多的参与机会，鼓励他们每一个人都能参与到课堂学习，充分调动他们每一个人的学习积极性。
4. 驾驭课堂的能力还需向老教师学习。以后多听老教师的课，多历练。
在今后的教学活动中，我将更努力地提升自己，继续探索在课堂教学中如何调动全体学生的积极性。
