2. Using the languages in the box of 1a to make comparisons (at least 10 sentences).课后自我反思
我认为本节课的可取之处:
1.在比较大象和熊猫两种动物时，我不是让学生仅仅用课本上提供的信息分别描述一下，而且还让学生进行了pairwork，一问一答进行对话，这样不仅对动物的体态、外观做了具体数据的表达，而且还复习了英语中如何表达长宽高的句型，学生也比较感兴趣。
2.在目标语言初步接触感知后，先进行简单的认读和操练，然后再进行深入的整编，让学有余力的同学可以有拓展和发挥的空间，同时也能让学生更好的理解和掌握目标语言的真实意义和用法,正真做到让学生体验内化语言的过程。
3.根据学生实际需要，在进行听力练习时，及时教授给学生听力技巧，使学生顺利完成听力任务，提高了听的能力。
不足之处：
1.在教学内容的设计上卡的过死，层次不够丰富，对于学有余力的同学而言，吃得不够饱。对于目标语言的拓展不够，局限性过强。课堂语言输入欠生动丰富。急于完成既定的教学任务，缺少对学生的正确引导和语言的真实深入的交流。
2.对于学困生不能顺利完成对话内容时，没有做出正确的引导和帮助，从而给学生带来了沮丧感。对于能顺利完成教学环节任务的学生，评价也不够到位，鼓励性不够强，评价过于笼统。对于学生启发不够。
3.课堂语言指令不够清楚，语言啰嗦，缺少真实性和有效性。
课后感悟
作为教师，要不断地学习和探索才能有足够的能力满足学生求知的欲望。而不是一味的抱怨学生的愚笨或教材不适用，教师应当反思自己的教学环节和教学思路、观点是否需要改进，是否符合学生的需求，以一丝不苟、谦虚谨慎的态度对待每一个教学细节。教师要懂得换位思考，多站在学生的角度上，放下为人师的架子，做一个温和而谦逊的引领者和帮助者。?????????????
教师在课堂中要善于机智地运用课堂学生资源，灵活地创设教学语境，启发学生思维。通过精心的教学设计，能幽默睿智地指引学生探究语言知识点，同时不断地激励学生通过目标语言的示例感知、体验、提炼、归纳、总结语言知识。在一堂听说课中，让学生乐意开口、激起主动交流的欲望。教师且能真正实践?“以学生为主体”的教学思想。教师要淡化每个任务的教学痕迹，春风化雨，润物无声，用活泼幽默的评价语言构建师生最自然、和谐、真实的交流互动，实现课堂教学效果的最大化。
