1、优质文本Unit 2 Healthy EatingI教学内容分析本单元的中心话题是健康饮食。主要是为了使学生对与健康有关的问题得到更好的理解。这一单元鼓励学生去检查自己的饮食行为，看一看它是不是健康的饮食习惯。一种健康的饮食习惯应该是平衡的，既不在脂肪、糖和盐这些方面过剩，又不会在人体必需的营养元素方面匮乏。通过本单元的学习，学生可以对健康饮食有一个清楚的概念，从而根据所学的知识去思考与健康有关的问题。Warming Up局部通过问题向学生询问饮食构成，让学生对本单元的内容能有一个初步的了解，并使学生复习与有关饮食的单词和短语。然后让学生答复一组问题，通过这些问题的讨论，引导学生参与表达自己的
