定語從句詳解：when、where和why引導的定語從句

一、基本概念

關系副詞的意思相當于“介詞+which結構”，在定語從句中做狀語的成分。

1.He will always remember the day when/on which his father returned from America.

他將永遠記得父親從美國返回的那一天

拆分后：

He will always remember the day.

His father returned from America on the day..

2.This was the time when/at which she left for Beijing.

這就是她動身去北京的時間。

拆分后

This was the time.

She left for beijing at the time.

3.I don’t know the reason why/for which he didn’t come to the meeting yesterday morning.

我不知道他為什么沒有參加昨天上午的會議。

I don’t know the reason.

He didn’t come to the meeting yesterday morning for the reason.

重要提示：

在when、where、why關系副詞引導的英語定語從句中，只會出現when、where、why或on which、at which、for which等等，絕對不會出現on when、at where、for why這種情況，因為關系副詞引導的定語從句只能起狀語作用，既不能做動詞的賓語，也不能做介詞的賓語。
