情景导入
学校食堂要改进菜单，英语老师趁机布置了一项任务：用英语写一写自己一天的健康食谱 My Healthy Diet。
小舟写下 I eat three rices every day. 同桌看了直摇头——rice 是不可数名词，不能加 s，也不能用 three 直接数！
写饮食作文，食物词汇和可数不可数是绕不开的两道关。这一讲我们边聊三餐边过关，让你把"吃什么、吃多少、为什么这样吃"写得清清楚楚。
核心词汇
饮食高频词汇：
| 类别 | 常用词汇 |
|---|---|
| 主食（多为不可数） | rice（米饭）、bread（面包）、noodles（面条，常用复数）、porridge（粥） |
| 蛋白质 | egg（鸡蛋）、fish（鱼肉）、chicken（鸡肉）、milk（牛奶）、beef（牛肉） |
| 果蔬 | vegetables（蔬菜）、tomatoes（西红柿）、apples（苹果）、bananas（香蕉） |
| 垃圾食品 | candy（糖果）、chips（薯条）、hamburgers（汉堡）、cola（可乐） |
量的表达：a lot of（许多）、some（一些）、a little（一点，接不可数）、a few（几个，接可数）、a bowl of（一碗）、a glass of（一杯）；饮食习惯：have breakfast（吃早餐）、keep a balanced diet（保持均衡饮食）
句型与结构
三段式结构：
- 开头段（观点）：We are what we eat. A healthy diet is important for us students.
- 主体段（三餐 + 原则）：按 For breakfast / For lunch / For dinner 依次写，再补一句饮食原则——I eat a lot of vegetables, but I seldom eat hamburgers.
- 结尾段（感受）：With this healthy diet, I feel great every day.
核心语法：可数与不可数名词的搭配
| 修饰词 | 接可数复数 | 接不可数 |
|---|---|---|
| a lot of / lots of | a lot of apples ✅ | a lot of milk ✅ |
| many / a few | many tomatoes ✅ | ❌ |
| much / a little | ❌ | a little juice ✅ |
提分句型：
- 三餐引导：For breakfast, I usually have an egg and a glass of milk.
- 对比句：I eat more vegetables and less meat.（多吃蔬菜，少吃肉。）
听说训练
写前口头操练（先说顺再下笔）：
- For breakfast, I usually have an egg and a glass of milk. （早餐我通常吃一个鸡蛋，喝一杯牛奶。）
- I eat a lot of vegetables and fruit every day. （我每天吃很多蔬菜和水果。）
- A healthy diet keeps me full of energy. （健康的饮食让我充满活力。）
辨析对比
| 修饰词 | 用法 | 例句 |
|---|---|---|
| many | 只接可数名词复数 | I eat many apples every week. |
| much | 只接不可数名词 | Don't drink too much cola. |
| a lot of | 可数不可数都能接 | I eat a lot of vegetables and drink a lot of water. |
文化角
西方营养学有"食物金字塔"（food pyramid）：塔底是谷物，中间是果蔬和蛋白质，塔尖是糖和油脂——越往上越要少吃。中国居民膳食指南也讲"谷物为主、餐餐有蔬菜"。杭州人的日常餐桌就很符合健康理念：一碗米饭、清蒸鱼、炒时蔬，饭后再来点龙井茶解腻。写作文时把 Longjing tea 和 steamed fish 写进去，既地道又有杭州味。
易错点
- 不可数名词加 s：three rices ❌ → three bowls of rice ✅，rice、bread、milk 都不可数。
- much 接可数名词：much apples ❌ → many apples ✅ 或 a lot of apples ✅。
- 三餐前用错介词：in breakfast ❌ → for breakfast ✅；“吃早餐”是 have breakfast，不加 the。
中考真题
假如你是李华，你校英语社团正在开展 My Healthy Diet 主题征文。请写一篇短文介绍你的健康食谱，内容包括：
- 你一日三餐通常吃什么；
- 你坚持的饮食原则（多吃什么、少吃什么）；
- 健康饮食给你带来的好处。
要求：70 词左右，可适当发挥。

We are what we eat, so a healthy diet is very important for us students.
For breakfast, I usually have an egg, some bread and a glass of milk. For lunch, I eat a bowl of rice with fish and a lot of vegetables. For dinner, I only eat a little, like some noodles and fruit. I try to eat more vegetables and less meat, and I seldom eat hamburgers or drink cola, because too much sugar is bad for my health.
With this healthy diet, I feel full of energy every day.
点评：① 结构清晰：观点—三餐与原则—好处；② a glass of / a bowl of / a little 等量词准确，可数不可数零失误；③ 亮点：more... less... 对比句、because 原因句；④ 约 95 词，内容具体。
