He has given up what he was devoted to to help the poor children in mountain

问题描述:

He has given up what he was devoted to to help the poor children in mountain

C D楼主,两个选项是一样的
首先固定搭配 be devoted to 这是被动式,原型为 devote to 意思是将自己贡献给……
所以D中的第一个 to 是固定搭配中的to
to help在句中做的是目的状语,不定式作目的状语
整句话的意思为,他已经放弃了所有去将自己献身于帮助村庄中的穷小孩的事业中
