定语从句说什么时候用when什么时候用which弄不清` 特别是修饰the day的时候`一会用那个`一会用这个`请教高手`

Answer 1

首先要读从句,看内容是否完整,
A.当缺主语或宾语时,用WHICH；
That was a fault which (could not be forgiven ).
I'll never forget the day _which__ we spent in Beijing.
We spent the day in Beijing.作宾语用which
B.当句子有主语谓语宾语,就可能是补状语了,用WHEN/where
1.I'll never forget the day _when_ (I first went to school).
I first went to school on that day.做状语用when
2.This is office _where__ (Lincoln once worked ).
Lincoln once worked in this office
