定语从句(Attributive Clauses)在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词(关系代词或关系副词)引出。精品小编准备了高一英语教案，具体请看以下内容。

总结：关系代词在从句中作宾语时，介词可提至关系代词前，构成“介词+which/whom从句”结构。注意：

(1)介词提前时，关系代词不可省略;

(2)介词提前时，只能用“介词+which”(指事物)以及“介词+whom”(指人)结构，此时不能用that或who。

(3)当关系代词作look after, look for, take care of等不能拆开使用的短语动词的宾语时，介词不能提前。

eg. 这是我们进行了很多讨论的问题。

This is the question about which we’ve had so much discussion.

我跟他说话的那个人是个老师。

The man to whom I spoke is a teacher.

关系代词前介词的确定

2. 形容词与介词的固定搭配

e.g. You’d better not bring your child to see the animals ______ which he is afraid.

3. 先行词与介词的搭配习惯

e.g. 1949 was the year_________ which the P.R.C. was founded.

KEY: in, of, in

[典型例题]

3. Who can give me the reason for which he hasn’t turned up yet?

Who can give me the reason why he hasn’t turned up yet?

关系副词都等于一个适当的介词+which，在从句中作状语

1. when在定语从句中作时间状语，相当于“介词+ 关系代词(which)”。

I’ll never forget the day when I joined the league.= I’ll never forget the day on which I joined the league.2. where在定语从句中作地点状语，相当于“介词+ 关系代词(which)”。

This is the house where I lived two years ago.

= This is the house in which I lived two years ago.3. why在定语从句中作原因状语，相当于“介词for+ 关系代词(which)”。

Do you know the reason why she was late?= Do you know the reason for which she was late.

when=in/at/on/…+which;

where=in/at/on/…+which;

why=for /…+which

注：区分关系副词与关系代词的区别。只要在定语从句中担任状语的，就是关系副词。

你还记得我们一起去参观博物馆的那一天吗?

Do you still remember the day when (on which) we went to visit the museum together?
