教学反思：
亮点：本节课是七年级上第七单元的语法课。学生对HOW MUCH问句已经有了一定的认识。一开始的借用图片复习物品名称及单复数名词，并通过短语及句子的翻译练习进一步巩固所学词汇及句型。Grammar Focus部分，先让学生汉译英，通过句子翻译总结归纳本单元重点语法即：询问单数物品时，用句型：How much is the/ this/that…? 回答：It’s+ 数额；询问复数名词是，用：How much are these/those…? 回答： They’re…同时，还引导学生总结归纳了指示代词、表颜色的形容词和衣物类名词的搭配关系。通过3a,3b的练习，从而巩固了询问您价格的句型。3c以轻松愉快地游戏方式让学生再次操练、巩固核心句型。
不足：课上时间关系，上台表演的学生太少，应压缩前面的时间，多给学生一些表演的机会，更能调动学习英语的热情和积极性。巩固训练还可以在多样化。
