where 可以引導(dǎo)所有類型的從句,只有在它引導(dǎo)定語從句時(shí) 才可能
和in which 替換,其他時(shí)候都不行.這取決于先行詞與介詞的搭配：
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：是否選擇when還是使用at which是有效性錯(cuò)誤的問題,時(shí)態(tài)才是關(guān)鍵,
但是日常做題目的時(shí)候可以這樣理解這個(gè)考點(diǎn)：時(shí)間狀語后面比如year,age,通常用when修飾,但是 介詞+which的修飾更優(yōu),往往更清晰.
for which是不是=why：很抱歉 我沒查到他們的區(qū)別 而我自己又認(rèn)為他們沒什么區(qū)別 他們可以互換
why是關(guān)系副詞 ,而for which 是介詞＋which結(jié)構(gòu)
關(guān)系副詞含義相當(dāng)于＂介詞＋which結(jié)構(gòu)＂,因此常常和＂介詞＋which＂結(jié)構(gòu)互換
其中
關(guān)系副詞有：when,where ,why
介詞＋which結(jié)構(gòu)有：
when =in/on which ,where=in/at which ,why =for which
對(duì)了 是在定語從句中的...
