一、基本概念?
關(guān)系副詞的意思相當(dāng)于“介詞+which結(jié)構(gòu)”，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(yuǎn)記得父親從美國(guó)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(dòng)身去北京的時(shí)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(huì)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(guān)系副詞引導(dǎo)的英語定語從句中，只會(huì)出現(xiàn)when、where、why或on which、at which、for which等等，絕對(duì)不會(huì)出現(xiàn)on when、at where、for why這種情況，因?yàn)殛P(guān)系副詞引導(dǎo)的定語從句只能起狀語作用，既不能做動(dòng)詞的賓語，也不能做介詞的賓語。
