from which等于什么?
from which是“介词+which=关系副词”这种形式来引导定语从句。例句:
The illness from which Mary is suffering has now been diagnosed as hepatitis.
这句话的主语是The illness from which Mary is suffering,主语里面有一个定语从句,which Mary is suffering from,从句里的主语是Mary, 从句谓语是is suffering from,从句的宾语是which。
from which的用法:
用法一:用于引导非限制性定语从句,在意义上相当于and from there(从那儿)。如:
He hid himself in a tree, from where he could see the enemy in the distance. 他躲在一棵树上,从那儿他可以看到远处的敌人。
用法二:可视为where前省略了the place,即这样用的from where 相当于from the place where,意思是“从……的地方”“离……的地方”。如:
From where I stood I could see everything clearly. 从我站的地方我一切都看得清清楚楚。
