情景导入
学校体育节要举办 Keep Fit, Keep Happy 主题演讲，老师请每位同学准备一篇短文，介绍自己保持健康的方法。
小舟每周都绕西湖跑步，可写成英文却只有一句 I like running. 老师问他：一周跑几次？每次跑多久？跑完感觉怎么样？他一个都答不上来。
写"健身方法"的关键就在这里：不能只说做什么，还要说清多久一次、做多长时间、带来什么好处。这一讲我们用频度副词和时间表达，把健身生活写具体。
核心词汇
健康生活高频词汇：
| 类别 | 常用表达 |
|---|---|
| 运动项目 | run（跑步）、swim（游泳）、play basketball（打篮球）、ride a bike（骑自行车）、do morning exercises（做早操） |
| 频度副词 | always（总是）、usually（通常）、often（经常）、sometimes（有时）、never（从不） |
| 频率表达 | once a week（一周一次）、twice a week（一周两次）、three times a week（一周三次）、every day（每天） |
| 作息习惯 | go to bed early（早睡）、get up early（早起）、have a good sleep（睡个好觉） |
句型与结构
三段式结构：
- 开头段（观点）：Health is very important to us. Here is how I keep fit.（健康很重要，下面是我的健身方法。）
- 主体段（方法 + 频率）：写 2~3 种方法，每种都带上频率和好处——I run around the West Lake twice a week. Running makes me strong.
- 结尾段（感受 + 呼吁）：Thanks to these habits, I'm full of energy. Let's do sports and keep fit together!
核心语法一：频度副词的位置
- 位于行为动词之前：I often play basketball after school.
核心语法二：How often 问频率，次数来回答
- How often do you exercise? — Twice a week.（一周两次。）
- "次数"表达：once（一次）、twice（两次）、three times（三次）及以上用 times。
提分句型：
- 动名词作主语：Swimming is a good way to keep fit.（游泳是保持健康的好方法。）
- be good for：Doing sports is good for our health.（运动对健康有好处。）
听说训练
写前口头操练（先说顺再下笔）：
- I usually run around the West Lake twice a week. （我通常一周绕西湖跑两次步。）
- Playing basketball makes me strong and happy. （打篮球让我强壮又快乐。）
- Doing sports is good for our health. （运动对我们的健康有好处。）
辨析对比
| 词 | 意思 | 例句 |
|---|---|---|
| sometimes | 有时（频度副词） | I sometimes swim on weekends. |
| sometime | 某个时候 | Let's play basketball sometime next week. |
| some time | 一段时间 | I spend some time running every day. |
文化角
英语中有句谚语：An apple a day keeps the doctor away.（一天一苹果，医生远离我。）西方学校非常重视体育，很多中学生放学后都参加运动俱乐部（sports club）。在杭州，绕西湖跑步、沿钱塘江骑行都是市民喜爱的锻炼方式，2023 年杭州亚运会之后，全民健身（fitness for all）更是成了热词——这些本地素材写进作文里，内容立刻真实又新鲜。
易错点
- 频度副词放错位置：I play often basketball ❌ → I often play basketball ✅，频度副词放在行为动词前。
- "两次"写错：two times a week 虽能看懂，但地道说法是 twice a week ✅。
- 动名词主语配错动词：Swimming are good for us ❌ → Swimming is good for us ✅，动名词作主语算单数。
中考真题
假如你是李华，你校英语报正在开展 How I Keep Fit 征文活动。请写一篇短文介绍你保持健康的方法，内容包括：
- 你常做的运动及频率；
- 你的健康作息习惯；
- 这些习惯给你带来的好处。
要求：70 词左右，可适当发挥。

Health is very important to us. Here is how I keep fit.
I usually run around the West Lake twice a week, and I often play basketball with my friends after school. Running and playing basketball make me strong. I also have good habits in my daily life. I always go to bed before ten and get up early, so I have a good sleep every night.
Thanks to these habits, I'm full of energy and I can study better. Let's do sports and keep fit together!
点评：① 三段清晰：观点—运动与作息—好处与呼吁；② 频度副词 usually / often / always 位置准确，twice a week 频率具体；③ 亮点：绕西湖跑步的本地情境、Thanks to 开头的结果句；④ 约 90 词，要点齐全。
考点
- 健康生活类作文对应七年级下 How often do you exercise 话题，期中期末高频出现；
- 核心考查：频度副词的位置、once / twice / three times 的频率表达、be good for 等好处句型；
- 备考策略：准备"两项运动 + 一条作息 + 一句好处"的语料包，任何健康话题作文都能快速组装。

诵读小贴士：诵读时特别留意 usually、often、always 出现的位置——都在动词前面；twice a week 连读要顺。首尾两句是健康类作文的万能开头和结尾，背熟后所有"健康生活"题目都能直接用。
