把“人”的信息融进句子，who 是你最得力的连接词！
一、什么是由 who 引导的定语从句？
在复合句中，如果我们要“补充说明一个人”，就可以用关系代词 who 来引导一个定语从句。
- who 用来指“人”；
- 它在从句中可以做主语或宾语；
- 通常紧跟在它修饰的人之后。
二、常见结构解析
✅ 作主语：
- The boy who is wearing a red cap is my brother.
（who = he，是从句的主语）
✅ 作宾语：
- The teacher who we met yesterday is very kind.
（who = the teacher，是从句的宾语）
⚠️ 如果是宾语，也可以用 whom，但在口语中通常直接用 who。
三、例句训练
- I saw a man. He was playing the guitar.
→ I saw a man who was playing the guitar. - She knows a girl. We invited the girl to the party.
→ She knows a girl who we invited to the party.
四、误区提醒
- ❌ I have a friend which likes music.
✅ I have a friend who likes music.
👉 修饰“人”不能用 which！ - ❌ The woman who you met her is my aunt.
✅ The woman who you met is my aunt.
👉 在从句中不要重复使用“her”。
五、写作范文片段赏析
My uncle, who works in a hospital, often tells me interesting stories about his patients.
I will never forget the teacher who taught me how to read when I was a child.
这些句子展示了 who 从句在人物描写中如何自然地补充细节。
六、小任务：试着自己合并句子
请你把下面两句话合并成一句话，用 who 引导定语从句：
- The girl is my cousin. She sings very well.
→ __________________________ - The man is famous. We saw him on TV.
→ __________________________
七、课堂小结
- who 是“人专用”的连接词；
- 它能连接两个句子，让表达更清楚；
- 在写作中常用来描写亲人、老师、朋友等人物。
