英语定语从句用法归纳

定语从句是由关系代词（如 who、whom、whose、which、what、as）和关系副词（如 where、when、why 等）来引导的，不过需要记住以下要点：

1. what 不能用于引导定语从句。

2.对于关系词的分析，必须要考虑它在定语从句中所充当的成分。

指人的关系代词包含 who、whose、whom、that。下面我们来进行分析：

The old man who/whom/that we visited yesterday is a famous artist.

Miss Wang is taking care of the child whose parents have gone to Beijing.

The man with whom my father shook hands just now is our headmaster.(=The man who/whom that my father shook hands with just now is our headmaster.) 注：

A. 指人的时候，有时只用 who 而不适合用 that。

1. 先行词是 one、ones 或者 anyone

(1)The comrade I want to learn from is the one who studies hard and works hard.

(2)Anyone who breaks the law should be punished.

2. 先行词是 these 时

These who are going to Beijing are the best students of our school.

3. 在 there be 开头的句子中

There is a student who wants to see you.

4. 一个句子中如果带有两个定语从句，其中一个定语从句的关系代词是 that，另一个则适合用 who，以此避免重复。

The student that won the first prize is the monitor who works hards.

5. 在非限制性定语从句中

A. I met a friend of mine in the street, who had just come from Japan.

B. 主句以 who 开头的句子中，只能用 that，不能用 who。
