1、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部分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。然后让学生回答一组问题，通过这些问题的讨论，引导学生参与表达自己的看法，激
2、发学生兴趣和好奇心，让学生自然而然地进入下一部分的学习。Pre-reading 部分通过几个问题讨论，让学生认识平衡营养的重要性，为课文的学习做出铺垫。Reading 部分主要讲述了王鹏和咏慧开饭店的故事，借此揭示了不同食物对人体有着不同的影响。故事讲诉了王鹏和咏慧两家饭店的两种饮食都是不合理的，经常去王鹏的饭店容易发胖，这样会导致高血压和心脏病等疾病；而经常去咏慧的饭店的顾客则容易变瘦，这样容易导致厌食或是营养不良，让学生注意并避免走这两种极端。这些距离学生自身生活很接近的问题很容易引起学生的思考。在教授的过程中注意积极的引导学生不断的进行反思。Comprehending第一部分通过True
3、 or False 第四部分通过Main idea的寻找，使学生对文章有了一个浅层的理解。Learning about Language 部分突出了词汇和语法的学习与训练。本单元的语法是情态动词ought to等的基本用法。Using Language 部分中包括了听、说、读、写几个部分的内容。学生可通过王鹏和咏慧的这一个事情，深入展开讨论与健康饮食有关的事情。阅读后的习题及讨论不仅帮助学生加深对文章主旨大意的理解，更重要的是让学生学会用所学的知识，解决在现实生活中遇到的问题。Learning Tip 部分主要建议学生学会通过学到的与健康饮食有关的内容，安排合理的膳食；让学生通过查询各种资料，
