　　课后反思
　　本节课是第六模块Unit4的阅读部分：Global warming. 我将这节课设计为目标导引、阅读导入、阅读、讨论、重难点讲解和巩固总结六个步骤。课后经过各位老师的点评，反思总结如下：
　　成功之处
　　一.引导学生一步步从阅读文章表层意思，到探讨深层意思。例如，Fasting reading 中设计回答问题，包括文意概括，然后到Careful reading中判断正误，最后总结全文，使学生从表面理解升华到深层理解，基本达到预期效果。学习目标也定位于理解文章，解读课文，在教学过程中，我提出一些难度适当的问题让学生思考、研究、探讨，鼓励他们进行合作交流。对于学生的回答，并没有咬文嚼字，而是给予充分的肯定，使学生内心充满自信和成功的喜悦。学生的合作小结，既尊重了学生的个性，又通过展示我的建议而保证了知识的精确性，有助于学生梳理知识，使其系统化。
　　二．借以利用课件和多媒体等符合学生心理年龄和兴趣趋向的教学手段来丰富学生的知识面，调动学生延展自己的思维，扩充自己的知识储备。
　　三．通过最后巩固总结这一环节引发学生对本节课的深入思考，进一步巩固所学知识。
　　不足之处
　　一．采用谈话方式导入虽然自然亲切，拉近了师生之间的情感距离，学习气氛宽松。 但是导入方式有点单一，不具有新颖性，独特性。
　　二．阅读后回答问题那部分，设计问题形式应该再多样化一些，这样才能在各方面给与学生锻炼。练习题给学生的时间不够充足，了解到有一些学生并未能在短时间内回答完所有问题。
　　三．在课堂上思路不够灵活。同时在设计时安排了太多的信息和内容，完成起来略显时间局促。
　　在以后类似的教学过程中，放手给学生，把课堂还给学生，给学生自由发挥的空间，是我一直在追求的目标。学生的潜力是无穷的。时刻记住：教师为引导，学生为主体。创设情景，激发情意，启迪学生思维，发挥学生的主动性和创造力，鼓励学生探索研究，这也是我在以后教学的追求目标。
