where 可以引导所有类型的从句,只有在它引导
定语从句时 才可能
和in which 替换,其他时候都不行。这取决于
先行词与介词的搭配:
This is the village where / in which I was born.
This is the village where / from which he joined the army.
This is the shool gate where / at which we met the other day.
I was born in the village.
He joined the army from the village.
We met at the school gate the other day.
at which是不是=when:是否选择when还是使用at which是有效性错误的问题,时态才是关键,
但是日常做题目的时候可以这样理解这个考点:时间状语后面比如year,age,通常用when修饰,但是 介词+which的修饰更优,往往更清晰。
for which是不是=why:很抱歉 我没查到他们的区别 而我自己又认为他们没什么区别 他们可以互换
why是
关系副词 ,而for which 是介词+which结构
关系副词含义相当于"介词+which结构",因此常常和"介词+which"结构互换
其中
关系副词有:when,where ,why
介词+which结构有:
when =in/on which ,where=in/at which ,why =for which
对了 是在定语从句中的...
望采纳。。。谢谢。。
