英语中定语从句的知识点剖析（2）

1、有哪些关系副词？

where when why

when: on/in /at/during which，主要作时间状语

where: in /on//at/to which,作地点状语

why: for which,作原因状语

2、下面是例句：

April 6th is the date when she was born.

You should keep the card in a place where you can find it easily.

1、关于介词+关系代词引导的定语从句

有两种点需要注意

第一点，有些动词+介词的固定词组不可以把介词拆开

如：

This is the book which I'm looking for.

不能改成下面的句子

This is the book for which I'm looking.

2、第二点，关系代词前介词的确定

根据从句动词习惯搭配。

I bought a great house on which I spent all my money.

这里的on使用，就是根据spent进行的。

3、根据先行词的习惯搭配

I'll never forget the time during which I spent my childhood in the country.

这里的during选择则是根据先行词time搭配的。

4、根据所表达的意思确定

The colorless gas without which we cannot live is called oxygen.

这里的without则是根据上下文意思选择的。

1、定语从句和同位语从句可以从两个方面看区别：

1.看关系词作不作成分

2.看从句表达的意思是不是先行词的内容

2、比如：

The news that our football team won the match was encouraging.

The news that we heard on the radio was encouraging.

第一个句子，关系词不作成分，就是同位语。
