Unit 2 Healthy Eating
路桥中学高一英语备课组
单元重点内容与教学目标
本单元的中心话题是“健康饮食”。通过这个话题，可以使学生学习与饮食有关的英语词汇和句型；掌握情态动词ought to 的用法；掌握提出建议和劝告（suggestions and advice）
的方式；看医生（Seeing the doctor）的句型以及表达同意与不同意（Agreement and disagreement ）的交际方式。另外，通过学习，帮助学生了解饮食结构与饮食文化、做到合理饮食，养成良好的饮食习惯，并且能学会一些为人处事之道，懂得如何正确处理矛盾，解决问题。这是贴近学生生活实际的话题,因此趣味性和实用性较强。
Warming Up 部分通过一个表格向学生展示了不同的食物类型，如：fast energy foods, slow energy foods, body-building foods, foods that give fiber for digestion and health, 向学生介绍了各种食物对人体的作用，然后通过询问学生的个人饮食习惯来引导学生关注平衡膳食。
Pre-reading 部分先让学生讨论Which food contains more sugar/fat /fiber/salt--- 然后通过对含量不同的食物的排序，使学生进一步了解哪些食品含糖/脂肪/纤维/蛋白质最多，那些食品最少。
Reading部分为故事的第一部分，主要讲述的是发生在饭馆中的故事，生动地描述了王鹏伟和咏慧所经营的不同的饭店之间的一场较量。由于他们的经营风格不同，菜肴不同，因此顾客对不同食品的反响也不同，从中也反映出在现代生活中人们对不同饮食时尚的追求。
Comprehending 部分分两小部分。第一部分通过判断正误的练习，使学生对文章有一个初步的理解。第二部分通过完成四个句子使学生了解到王鹏伟和咏慧两个饭店各自的优势和劣势。
Learning about language 部分Discovering useful words and expressions 主要让学生通过上下文在语篇中学习词汇，注意不同词性间的转化。Discovering useful structures 让学生在文章中找出含有情态动词的用法，并能在交际中灵活地运用情态动词。
Using Language 部分分为听、读、说和写三个小部分。
听的部分是主体阅读文章的延续，主要讲述了王鹏伟到图书馆查找资料，发现他和咏慧的饭店提供的事物营养都不够均衡，从中学到许多有关健康食品的知识。通过听，学生了解到哪些是能量食品（Energy-giving foods），哪些是健身食品(Body- building foods)，哪些是保健食品(Protective foods)，还有两家餐馆所提供的食物的营养和作用。
读的部分为故事的第二部分，正所谓不打不相识，经过一段时间的切磋，王鹏伟和咏慧决定联起手来，提供给顾客营养均衡的食品，最后两人也幸福地结成了连理，整个故事以喜剧结局。
说和写部分结合了生活的实际，让学生两人一组研究中餐并设计食谱，使学生将书本所学的知识运用到实际生活中，锻炼其口语和书面表达能力。
Learning tip部分教会学生如何判断包装食品和罐装食品的均衡营养。学生在研究这些食品的同时也可扩大词汇量。
Unit 2 Healthy eating
背景小资料：
Healthy foods
The foods we eat at meals, or grab from the fidge between commercials, contain tiny chemicals called “nutrients”（营养物质）. Our bodies are made up of trillions of（数以百万兆的） tiny cells（细胞） that need small amounts of these nutrients every day to give us energy, and help build and repair our body tissues（组织）. These nutrients are grouped into six different categories（种类，类别）.
Carbohydrates (碳水化合物) Vitamins（维生素）
Fats （脂肪） Minerals (矿物质)
Proteins （蛋白质） Water
Variety（多样性） is key, but practice makes perfect. So fitting food guide foods into your diet will be as easy as “low-fat” diet. You’d better eat all kinds of foods, even if what you dislike, then you can keep healthy and thinner.

( more beautiful / slim ; She is famous not only for her parents but also for her success in losing 32 kilos in weight .)
