Where do you plan to work?I've made up my mind to go where I'm most needed.

问题描述:

Where do you plan to work?I've made up my mind to go where I'm most needed.
这里用where不需要先行词的吗?为什么to which不行?我觉得两个一样啊.如果是知识点希望给出详细解答,不要牵强附会~

这里where所属的句子不是定语从句,只有定语从句需要先行词,这是一个WHERE引导地点状语从句,如果想用to which的话,应该是 I've made up my mind to go to one place which I'm most needed to go.
