人教版高中英语必修3 Unit2 单元教材分析
Unit2 单元教材分析Unit 2 Healthy eating[单元分析]一、教材分析本单元的中心话题是“健康饮食”。
教材通过讲述王鹏和雍慧开饭店的不同风格、经营的不同菜肴以及顾客对不同食品的反应，反映了现代人对饮食的关注和对时尚的追求。
这样的编排有别于惯常所采用的分类说明的介绍方式，读起来引人入胜，学生在趣味盎然的故事情节中轻松学习健康饮食的知识，领悟膳食平衡对身体健康的作用，养成热爱钻研的好习惯。
王鹏的故事分成三个部分呈现在学生用书之中：第一部分是主阅读文章，王鹏和雍慧为吸引客源展开竞争，用菜肴的功效来做宣传;第二部分是听力短文，王鹏为研究膳食平衡，向专家请教;第三部分也是阅读短文，王鹏和雍慧合作，共同为顾客提供均衡的健康饮食，最后他俩喜结良缘。
“热身”(Warming Up)部分通过图片和表格向学生展示食物的分类法，探讨各类食物对人体的作用，然后通过询问学生的个人饮食习惯来引导学生关注膳食平衡。
这样的安排为后面的阅读和听力理解提供了背景知识，扫除了学生的知识障碍和语言障碍。
“读前”(Pre-reading)部分设计了讨论题:你认为健康均衡的饮食应该包含哪些种类的食物？款待朋友，你们当地用什么特色菜？让学生列出一个菜单。
然后让学生根据文章标题和插图来预测内容。
讨论题有助于调动学生的相关背景知识，为深人理解阅读文章的内容做铺垫。
“阅读”(Reading)部分主要讲述了王鹏和雍慧开餐馆竞争的故事。
王鹏的饭店近来生意不好，他尾随老顾客到了雍慧的小餐馆，发现雍慧为顾客提供的食物很简单，只有米饭、蔬菜、水果和水。
由于雍慧宣称这些食物能减肥，所以吸引了很多顾客，生意很火爆。
王鹏在图书馆查找资料，发现自己和雍慧的餐馆提供的食物都存在片面性。
自己的餐馆提供的食物含脂肪太多，雍慧餐馆提供的食物虽然可以减肥，却不能为顾客提供足够的热量，不利于身体健康，自己的餐厅却能弥补这个不足。
文章结尾一句话The competition between the two restaurants was on!给读者留下了悬念，引发兴趣，使学生有继续读故事的欲望。
