The shorter boy replied,"When someone hurts you, you should write it in the sand from which the wind can erase it easily. However, when someone does something good for you, you should carve it on a stone from which the wind can never erase it."
这两句话中的from which是什么意思,在句中是什么用法呀?应该说如何理解?
我觉的这可能是个定语从句,先行词是sand 和stone。which是个关联词在这里代替先行词。并且在定语从句中做宾语,做介词from的宾语。本来当关联词代替先行词做宾语时可以用that或which,可是在这儿介词提前了,只能用which。不知道我这样理解合适吗?请高手指点!

定语从句
the wind can erase it easily from the sand

from which是从...上除去的意思.
the wind can erase it easily from the sand 风会很容易地将它从沙上吹走
the wind can never erase it from a stone 风无法将它从石头上吹走

矮个子的男孩说“当谁伤害了你,你应该把它写在容易被风吹没得沙子上。但是,当谁帮助了你,你应该在把它刻在永远也擦除不掉的石头上”
都指代前一个名次~分别为sand和stone

你的解释很对
