定语从句的用法总结
一、什么是定语从句
定语从句是英语中一种常见的短句结构，用来修饰和限制名词或代词。

它通常由关系代词（如that, who, which）引导。

在一个句子中，定语从句常位于被修饰名词或代词之后。

二、定语从句的引导词
1. that: 在非限制性定语从句中，that可以指人也可以指物。

2. which: 在非限制性定语从句中，which只能指物。

3. who: 常用来引导指人的非限制性定语从句。

4. whom: 作为宾格时引导指人的非限制性定语从句。

三、在哪些情况下可以省略引导词
1. 当关系代词在被修饰名词后面做介宾时，可以将其省略。

例：This is the book (that) I am reading.（我正在读的这本书）
2. 如果关系代词在非限制性定语从句中作主格，且前面有逗号隔开，则可以将其省略。

例：Tom, who came from Canada, told me the news.
