教学后记：本节课主要是教授六个单词和两个句型。先巩固旧的知识，从而引出新的单词。新单词学习的时候可以适当给学生们输入一些元音的发音，每教2个单词做个小操练，让学生们能把单词滚动起来学习，这个部分支持他们掌握的不错。但是句型的教学出现较太晚，学生们不能得到充分的练习。应该把句型在教第一个新单词的时候就进行输入，让学生跟着模仿。尽量把单词和句型融合在一起来教学，这样会达到更好的效果。在教授is this a …和is that a …的句式时，以更直观更能使学生明确理解的方式，这样才能让他们深刻体会is this和is that的区别。操练这两个句型时，若能请学生用自己带来的key,redio, clock…，操练的气氛和效果就会更好了,同时老师也能带出下部分的内容，先让学生接触句型‘what a nice… can i have a look? sure. here you are!’再第二节课的时候，可以试着这样去改进。
