用非限制性定语从句，给写作加分的高级句式
✅ 一、什么是非限制性定语从句？
📌 非限制性定语从句（Non-restrictive Relative Clause）用于对先行词进行补充说明，即使去掉从句，主句含义依然完整。
常由 who, which, whose, where 等引导，并且从句前有逗号隔开。
示例：
My father, who loves gardening, grows many flowers.
✏️ 二、非限制性 VS 限制性定语从句
| 限制性定语从句 | 非限制性定语从句 | |
|---|---|---|
| 功能 | 必须限定先行词含义 | 补充信息，去掉不影响 |
| 标点 | 无逗号 | 需用逗号隔开 |
| 例句 | The man who is talking is my teacher. | Mr. Brown, who is talking, is my teacher. |
🌟 三、常见引导词
✅ who / whom —— 人
✅ which —— 物
✅ whose —— 所有关系
✅ where / when —— 地点/时间
示例：
She gave me a gift, which was very beautiful.
Linda, whose father is a doctor, studies hard.
🗂️ 四、易错点提醒
❌ 非限制性从句不能用 that 引导。
错误： This book, that I bought yesterday, is interesting.
正确： This book, which I bought yesterday, is interesting.
✅ 别忘了用逗号分隔。
I met Mary who is my classmate. (✘)
I met Mary, who is my classmate. (✔)
✍️ 五、写作中如何巧用
✨ 在议论文、记叙文中穿插非限制性定语从句，可让句子更连贯、信息更丰富：
Pollution, which affects everyone, needs urgent solutions.
My uncle, who works abroad, visits us every year.
📝 六、课后练习
请将括号内信息补充为非限制性定语从句：
- My sister (she is a nurse) works in the city.
- This museum (it was built in 1900) attracts many tourists.
- Mr. Wang (he teaches math) is very patient.
