初中定语从句知识点详解.doc初中定语从句知识点详解
定语从句考点：①关系代词的用法
②关系副词的用法
③关系副词 =介词 +关系代词的用法
●定语从句：在主从复合句中用作定语的从句叫做定语从句。
Eg time when we worked on the farm.
我永远不会忘记我们一起在农场工作的时候。
He arrived in Beijing on the day when I left. 他在我离开北京的那天到的北京。
where 指地点，在定语从句中作状语。例如：
This is the house where we lived last year. 这就是我们去年居住的那个房子。
=This is the house which we lived in last year. =This is the house in which we lived last year.
The factory where his father works is in the east of the city.
他父亲工作的那个工厂在这个城市的东边。
=The factory which his father works in is in the east of the city.
=The factory in which his father works is in the east of the city.
why 指原因，在定语从句中做原因状语：
I don ’ t knowthe reason why he looks sad today. 我不知道他今天看起来难过的原因。
Could you please explain the reason why you were late? 你可以解释下迟到的原因吗？
（二）关系代词和冠词副词引导的从句有什么区别？
关键点： 1、关系副词在从句中是做 状语，只做状语，不能做其他的成分。
2、关系副词引导的从句可以由 “介词 +关系代词 ”引导的从句替换。
why=for which
where=in/on/at /to ·which(· 介词同先行词搭配）
when=during/on/in/over ··which· （介词从同先行词搭配）
注意： 介词后面的关系代词不能省略 介词后面不能用

that。
eg： The reason why he refused the invitation is clear. 他拒绝邀请的理由显而易见。
=The reason for which he refused the invitation is clear.
Great changes have taken place in the city where I was born.
我出生的地方发生了巨大的变化。
=Great changes have taken place in the city in which I was born.
The time when we got together finally came. 我们团聚的时刻最终到来了。
=The time in/during which we got together finally came.
[ 注 ]表示时间 “ time"一词的定语从句只用 when 引导，有时不用任何关系代词， 当然也不用 that 引导。
Eg: By the time you arrived in London, we had stayed there for two weeks.
到你来伦敦的时候，我们已经在那里待了两天了。
I liked the sea city the first time I went there. 我第一次来到那个海滨城市就爱上了它。
例题一：
1、 He has forgotten the day _______ he arrived.
A. when B. where C. that D. which
解题思路：此题中，从句是 he arrived，它已经是一个完整的句子，因此，这里要填一个在
从句中充当状语的成分， C 选项和 D 选项都不能做在从句中作状语，因此排除掉， the day
指的是时间，因此，要填上表示时间的关系副词 whe
