Where引导的定语从句
基本用法
where 引导定语从句时，先行词是表示地点的名词，where 在从句中作地点状语，相当于“介词 + which”。
结构：先行词（地点名词）+ where + 从句
例句：
- This is the house where I was born. （= in which I was born）
- The school where he studies is very famous.
先行词的类型
具体地点名词
- the city, the village, the house, the school, the factory 等
Beijing is the city where I grew up.
抽象“地点”名词
先行词也可以是表示“抽象地点”的名词，如：
- point, stage, situation, case, condition, position, activity, job, family 等
We reached a point where we had to make a decision. He's in a situation where he has no choice.
where = 介词 + which
| 定语从句 | 等价表达 |
|---|---|
| the house where I live | the house in which I live |
| the city where she works | the city in which she works |
注意：介词的选择取决于从句中动词的搭配。
易错点与辨析
✅ 用 where 的情况：从句缺地点状语
This is the factory where my father works. （works 不缺宾语，缺地点状语 → 用 where）
❌ 不用 where 的情况：从句缺主语或宾语
This is the factory that/which I visited last year. （visited 缺宾语 → 用 that/which，不能用 where）
判断口诀
从句成分完整 → 用 where（作状语） 从句缺主/宾 → 用 that/which（作主/宾）
特殊注意
先行词为地点的名词，但从句缺主语/宾语时
❌ This is the house where he bought. ✅ This is the house that/which he bought.
关系副词 where 不能换成 that
❌ the house that I live ✅ the house where I live
非限制性定语从句中也可用 where
They went to London, where they stayed for a week.
与先行词 distance, direction 等搭配
He hid himself in a corner where he could see the door.
典型练习
- This is the village ___ I spent my childhood. （where）
- This is the village ___ I visited last year. （that/which）
- We've reached a stage ___ we must change our plan. （where）
- Is this the reason ___ he explained? （that/which，不是why）
