情景导入
课间十分钟，同学们聊起了最喜欢的科目。有人喜欢数学，"because it's interesting"；有人喜欢体育，"because it's relaxing"；你举手说：My favourite subject is English, because I want to be a volunteer like the ones at the Hangzhou Asian Games.
说清"最喜欢什么 + 为什么"，是本单元的核心任务。这背后藏着一个大语法——一般现在时：说到 "He likes art."，动词为什么要加 s？这一课全讲明白。
核心词汇
学科名称：
| 单词 | 意思 | 例句 |
|---|---|---|
| Chinese / English | 语文 / 英语 | I like English best. |
| math / science | 数学 / 科学 | Math is difficult but interesting. |
| history / geography | 历史 / 地理 | History tells old stories. |
| art / music | 美术 / 音乐 | Music makes me happy. |
| P.E. / I.T. | 体育 / 信息技术 | We play basketball in P.E. |
评价形容词：interesting（有趣的）、boring（无聊的）、difficult（难的）、easy（容易的）、useful（有用的）、relaxing（令人放松的）、fun（有趣的）；其他：favourite（最喜欢的）、subject（学科）、because（因为）、why（为什么）
句型与语法
核心句型：询问与表达最爱
- What's your favourite subject? — My favourite subject is music.
- Why do you like it? — Because it's relaxing.
核心语法：一般现在时（表示习惯、事实、喜好）
- I / you / we / they + 动词原形：I like science.
- he / she / it（三单）+ 动词加 s/es：She likes history.
三单变化规则：一般加 -s（like → likes）；以 s / x / ch / sh / o 结尾加 -es（teach → teaches, go → goes）；辅音字母 + y 结尾变 y 为 -ies（study → studies）。
否定与疑问（借助 do / does）：
- I don't like math. / He doesn't like math.（doesn't 后动词还原）
- Do you like art? — Yes, I do. / Does she like P.E.? — No, she doesn't.
听说训练
学科喜好采访（采访三位同学并记录）：
- A: What's your favourite subject? — B: My favourite subject is geography.
- A: Why do you like it? — B: Because I can learn about different places, like the West Lake and the Qiantang River.
- A: Who teaches you geography? — B: Ms. Wu. Her classes are never boring.
辨析对比
① don't vs doesn't
- I / you / we / they + don't：They don't have art on Monday.
- he / she / it + doesn't：He doesn't like math.（doesn't 已含三单信息，后面动词用原形）
② Why 提问，Because 回答：Why do you like English? — Because it's useful. 二者是固定"问答搭档"，答句不能再用 so。
③ fun vs funny
- fun：有趣的、令人开心的 → P.E. is fun. 而 funny：滑稽好笑的 → The story is funny. 夸一门课有意思用 fun / interesting，用 funny 就像在说这门课"很搞笑"。
文化角
英美中学生可以自选课程：除了必修的英语、数学，还能选戏剧（drama）、木工（woodwork）、烹饪（cooking）等有趣的科目。拼写小知识：favourite 是英式拼法，美式拼成 favorite；考试中两种都算对，但同一篇作文里要保持一致。
易错点
- 三单 -s 漏加：My brother like music. ❌ → My brother likes music. ✅
- doesn't 后动词不还原：She doesn't likes art. ❌ → She doesn't like art. ✅
- 学科名首字母：Chinese、English 由国家名而来必须大写；math、music 等普通学科小写即可。
- because 和 so 连用：Because it's fun, so I like it. ❌ → 二选一：It's fun, so I like it. ✅
中考真题
— ______ does Linda like science? — Because she wants to know how things work.
A. What B. When C. Why D. Where
✏️ 点击查看解答
答案：C
解析：答语以 Because（因为）开头，说明问句在询问原因，特殊疑问词只能用 Why。Why 问原因、Because 答原因，是英语中固定的"问答搭档"。A 项问"什么"、B 项问"何时"、D 项问"何地"，都无法用 Because 来回答。
考点
- 一般现在时三单变化（-s/-es/-ies）是七上最重要的语法考点，单选、语法填空、短文改错全覆盖；
- do/does 引导的否定句和一般疑问句，重点盯"doesn't/don't 后动词还原"；Why...? Because... 的问答配对是情景交际高频题；
- 书面表达：My Favourite Subject 是经典作文题，结构"最爱学科 + 两个理由 + 老师评价"即可成文。
诵读 Read Aloud
Part 1 · 对话：聊聊最爱的科目（分角色朗读）
A: Hi, Tony! What's your favourite subject? — B: My favourite subject is history. I like old stories about the past.
A: What about you? — B: I like English best, because it's useful. My teacher Ms. Li makes every class fun, and she often tells us stories about the Hangzhou Asian Games.
Part 2 · 短文：English, My Favourite（喜好表达范文）
I'm a student in Hangzhou, and my favourite subject is English. Why do I like it? First, English is useful. Many visitors come to the West Lake every year, and I can show them around in English. Second, my English teacher, Ms. Li, makes every class interesting. We sing songs, play games and read fun stories. I also like science, because it tells me how things work. But English is always my number one. I study it every day, and I want to be a volunteer for big events in my city!
诵读小贴士：Part 2 用 First... Second... 列理由，是"喜好类"作文的万能骨架；朗读时圈出所有三单动词（makes、tells），加深 -s 规则的印象。
