which 也能引导定语从句？搞懂它就能写出高级句！

和 that、who 并列的第三位“连接王者”，掌握从句表达不再难

一、什么是 which 引导的定语从句？

在定语从句中，which 用于修饰事物或动物，在从句中可作主语或宾语，是表达“某物是什么”、“某事物有何特点”等核心工具。

二、基本句型讲解

✅ 作主语：

• I saw a cat which was very fat.
  （which 在从句中做主语）

✅ 作宾语：

• She bought a dress which she wore to the party.
  （which 在从句中做宾语）

三、和 that 的对比

📌 举个对比例子：

• The book which is on the table is mine. ✅
• The book that is on the table is mine. ✅
  （语义一致，which 更正式）

四、非限制性定语从句中只能用 which

如果用逗号隔开，是“补充说明”作用的非限制性定语从句，此时不能使用 that，只能使用 which。

❌ 错误：My car, that is red, is new.
✅ 正确：My car, which is red, is new.

五、例句转换练习

请将两个句子合并成一个包含 which 的定语从句：

1. This is the cake. You made this cake.
   ✅ This is the cake which you made.
2. I watched a movie. The movie was exciting.
   ✅ I watched a movie which was exciting.

六、范文片段赏析

I live in a city which has a long history.
The museum, which was built in 1901, attracts many visitors every year.

这个片段展示了 which 在限制性和非限制性定语从句中的不同表达效果。

七、课堂训练小任务

请用 which 引导定语从句写出下面句子的合并版本：

1. She showed me a photo. The photo was taken last year.
2. I read a book. It changed my opinion.
