一、 教学目标 (Teaching Aims)
1. 语言知识目标:
词汇: 掌握并运用核心词汇与短语,如 balanced diet, food guide pagoda, grains, dairy, different kinds of, come down to, along with。

说/写: 能运用所学词汇和句型,简单描述“膳食宝塔”的结构,并为自己或他人制定简单的健康饮食计划。
3. 情感态度与文化意识目标:
通过了解“中国居民膳食指南”,增强学生对健康饮食的重视,引导他们反思并改善自己的日常饮食习惯。
让学生认识到,健康不仅仅是吃得好,还包括运动、睡眠和压力管理。
二、 教学重难点 (Teaching Key & Difficult Points)
教学重点:
1. 理解“膳食宝塔”五层结构所代表的食物分类及其对应的英文表达。
2. 掌握描述健康饮食方式的核心短语。
教学难点:
1. 理解并运用较长的句子,如 A balanced diet means eating different kinds of foods in the right amount to stay in good health.
2. 将课文中的健康理念,转化为自己实际的一日三餐计划。
三、 教学准备 (Teaching Aids)
多媒体课件(PPT):包含清晰的“中国居民膳食宝塔”图片(最好有英文标注)。
小黑板/白板。
准备一些常见食物的图片或单词卡(如:rice, noodles, apples, pork, milk, oil等)。
四、 教学过程 (Teaching Procedures)
Step 1: Warming-up & Review (5 mins)
1. Review (复习回顾): 快速回顾上一单元话题,建立联系。
T: Last class, we talked about Danny. He had a stomachache after playing basketball. Why? (引导学生回答:He ate right after the game. He drank too much cold water.)
T: So, what we eat and how we eat is very important for our health. Today, we will learn A healthy way of eating. (板书课题)
2. Free Talk (自由谈话): 提问学生,拉近距离,引出话题。
T: What did you have for breakfast this morning?
(请2-3位学生回答,教师用简单的英文重复,如:Oh, you had some noodles. You had porridge.)
T: Do you think your breakfast is healthy? Let's find out!
设计意图: 从上一课的“运动与健康”自然过渡到本课的“饮食与健康”,并通过询问学生实际早餐情况,让学习内容与他们的生活经验直接挂钩,激发学习兴趣。
Step 2: Pre-reading & While-reading (15 mins)
1. Introduction of “Pagoda” (引入“宝塔”概念):
教师在PPT上展示“中国居民膳食宝塔”图片。
T: Look at this picture. It looks like a pagoda (宝塔). It's called the Chinese food guide pagoda. It tells us what and how much to eat. It gives us a balanced diet (板书并领读这两个关键短语).
2. Fast Reading (快速阅读 - 匹配任务):
让学生快速阅读课文第二段,完成课本上的“Label the Chinese food guide pagoda”任务。
教师可以降低难度,将五层食物名称写在黑板上(打乱顺序),让学生连线匹配。
(Level 5 - Top: Salt and oil; Level 4: Milk, dairy, soybeans, nuts; Level 3: Meat, fish, eggs; Level 2: Vegetables and fruits; Level 1 - Bottom: Grains, cereals, potatoes)
3. Detailed Reading (精读与信息提取):
让学生再次阅读课文,完成课本第三部分的两个问题。
A. How can we develop a healthy way of eating? (从文中找答案:Start with a healthy breakfast. Eat three or more types of food from the pagoda. Have milk every day.)
B. According to the author, what should we do to live a healthy life? (从文中找答案:Regular exercise, enough sleep, and dealing with pressure are also important.)
语言点精讲:
讲解 different kinds of (不同种类的):举例 different kinds of fruits, different kinds of exercise。
讲解 come down to (归根结底,取决于):用简单句解释,如 It all comes down to having a balanced diet. = The most important thing is having a balanced diet.
讲解 along with (和,连同):举例 I eat some bread along with an egg.
设计意图: 利用形象的“宝塔”图片,将抽象的文字转化为直观的图像,帮助学生理解。通过精读和回答问题,训练学生提取关键信息的能力。精讲语言点,为学生后续的输出活动打下基础。
Step 3: Post-reading & Practice (巩固与操练) (15 mins)
1. Complete the Conversation (完成对话填空):
让学生独立完成课本第四部分的填空练习。
(Answers: different kinds of, along with, comes down to, stay healthy)
完成后,教师带领全班朗读对话,或让学生两人一组练习朗读。
2. Pair Work / Group Work (小组合作 - 制定健康饮食计划):
任务布置: 这就是课本第五部分的任务。让学生两人或四人一组,用英语讨论并制定一份“健康饮食一日计划”。
提供框架 (Scaffolding): 教师在黑板上给出提示句型,帮助学生组织语言。
For breakfast, we should eat... (e.g., porridge, an egg, and some vegetables.)
For lunch, we need to have... (e.g., rice, fish, and soup.)
For dinner, it's good to eat... (e.g., noodles and some fruit.)
We should also drink... (e.g., milk and lots of water.)
We need to avoid... (e.g., too much oil and salt.)
展示环节: 请2-3个小组上台分享他们的饮食计划。学生表达有困难时,教师用英文或中文协助。
设计意图: 对话填空是机械操练,帮助学生巩固短语。而制定健康饮食计划是任务型教学的体现,让学生将所学知识应用于解决真实问题(为自己设计健康食谱),能够有效锻炼学生的综合语言运用能力和合作学习能力。
Step 4: Summary & Homework (总结与作业) (10 mins)
1. Summary (课堂小结):
教师指着膳食宝塔图,带领学生回顾今天所学的主要内容。
T: Today we learned about the Chinese food guide pagoda. It has five levels. At the bottom, we have grains. At the top, we have salt and oil.
T: A healthy way of eating is a balanced diet. Remember: start with a good breakfast, eat different kinds of food, and have milk every day.
情感升华: 同学们,你们正在长身体的时候,一定要吃好三餐,不要挑食。健康的身体是学习的本钱。
2. Homework (课后作业 - 分层布置):
基础作业 (必做): 抄写并背诵本节课的重点词汇和短语(balanced diet, pagoda, grains, dairy, different kinds of, come down to)。
提高作业 (选做): 用英文写一篇50词左右的小短文,介绍“膳食宝塔”中你最熟悉的一层(如谷类或蔬菜水果),并说明为什么它们对健康有益。
实践作业 (兴趣): 回家后,用今天学到的知识,给你的家人提一条关于健康饮食的建议,并尝试用英语说给家人听(哪怕只说一句也行)。
