情景导入
九月底，学校操场上摆满了社团招新的摊位：音乐社、篮球社、书法社、英语角……音乐社的学长问你："Can you play the guitar?" 你自信地回答："Yes, I can. And I can sing, too!"
一个小小的 can（能、会），就能把你的十八般武艺全部展示出来。它还有个特点：不管主语是谁，can 永远不变形——这可比三单 -s 省心多了。这一课，我们用 can 聊社团、秀才艺、交朋友。
核心词汇
社团名称：
| 单词/短语 | 意思 | 例句 |
|---|---|---|
| music club | 音乐社 | I want to join the music club. |
| art club | 美术社 | The art club meets on Friday. |
| chess club | 棋社 | He is in the chess club. |
| sports club | 体育社 | The sports club is popular. |
才艺动词短语：play the guitar（弹吉他）、play the piano（弹钢琴）、play chess（下棋）、sing（唱歌）、dance（跳舞）、draw（画画）、swim（游泳）、tell stories（讲故事）；其他：join（加入）、show（展示）、talent（才艺）、be good at（擅长）
句型与语法
can 的三大特点：
- 不变形：无论 I / she / they，一律用 can → She can dance.（不是 cans ❌）
- 后接动词原形：He can swims ❌ → He can swim ✅
- 否定疑问不借 do：否定直接加 not（can't），疑问把 can 提前。
四种句式一览：
- 肯定：I can play chess. / 否定：I can't（= cannot）play the piano.
- 一般疑问：Can you draw? — Yes, I can. / No, I can't.
- 特殊疑问：What can you do? — I can sing and dance.
加入社团的表达：I want to join the music club. / What club do you want to join? — The English club.
乐器与球类的冠词规则：play the guitar / the piano（乐器加 the）；play basketball / chess（球类、棋类不加 the）。
听说训练
社团招新面试（一人当社长，一人当新生）：
- A: Welcome! What club do you want to join? — B: I want to join the music club.
- A: Can you play the guitar? — B: No, I can't. But I can sing very well.
- A: Can you sing an English song now? — B: Sure! Listen...
辨析对比
① can vs can't 的听力辨音
- I can swim. 中 can 弱读又轻又快；I can't swim. 中 can't 重读且拖长。
- 听不清时看语境：后一句是 "Let's go to the pool!" 多半是 can；是 "So I'm afraid of water." 则是 can't。
② play + the + 乐器 vs play + 球类/棋类：乐器加 the（play the piano / the violin）；球类棋类不加（play basketball / play chess）。口诀：乐器"贵"要戴 the，球棋"随便"不用戴。
③ join vs join in：join + 组织/团体（join the club）；join in + 活动（join in the game）。加入社团用 join，参加活动用 join in。
文化角
社团（club）文化在英美学校非常发达：戏剧社、辩论社、机器人社应有尽有，大学申请时社团经历甚至和成绩一样重要。在杭州，不少中学也有龙舟社、茶艺社、亚运志愿服务社。向外国朋友介绍茶艺社可以说：In our tea club, we can learn to make Longjing tea.
易错点
- can 后动词加 s：She can sings. ❌ → She can sing. ✅（can 后必须原形）
- can 借 do 提问：Do you can swim? ❌ → Can you swim? ✅
- 乐器漏 the：He can play guitar. ❌（规范书面语）→ He can play the guitar. ✅
- cans 变形：My sister cans dance. ❌ → My sister can dance. ✅（can 永不加 s）
中考真题
— Can Tom play ______ chess? — Yes, he can. But he can't play ______ piano.
A. the; the B. /; the C. the; / D. /; /
✏️ 点击查看解答
答案：B
解析：本题考查 play 的冠词搭配：棋类、球类前不加 the（play chess / play basketball）；乐器前必须加 the（play the piano / play the guitar）。第一空 chess 是棋类，不加冠词；第二空 piano 是乐器，加 the。因此选 B。
考点
- 情态动词 can 的三大特点（不变形、接原形、不借 do）是七上必考语法，单选和改错的常客；
- play + the + 乐器 / play + 球棋类的冠词区别几乎年年出现在各地考卷中，can/can't 的重弱读辨音是听力经典题型；
- 书面表达：招新海报（Join Our Club!）和才艺自我介绍是本单元特色作文，多写几句 I can... 就是亮点。

Part 2 · 短文：Our Fun Clubs（社团介绍范文）
There are many fun clubs in my school in Hangzhou. In the music club, students can sing and play the piano. In the sports club, we can play basketball and run on the playground. My favourite is the tea club. In this club, we can learn to make Longjing tea, the famous green tea of Hangzhou. I can't make it very well now, but our teacher says practice makes perfect. What can you do? Come and join our clubs — there is always one for you!
诵读小贴士：Part 1 注意 can（弱读）和 can't（重读）的对比；Part 2 末尾的 "Come and join our clubs!" 是海报体经典结尾，写招新作文时直接借用。
