用to 是因为介词词组 return to 至于答题方法,其实介词+关系代词,那个介词用哪一个,一要看固定搭配,二要看句子的意思决定动词后面用什么介词.This is the house in which I lived two years ago.（live in）The school in which he once studied is very famous.（study in someplace）Tomorrow I will bring here a magazine for which you asked.(ask for sth)希望能帮到你吧.o(∩_∩)o 哈哈======以下答案可供参考======供参考答案1:C.to which 定语从句：介词+关系代词风能是一种古老的能源，我们可能在不久的将来就可能达到。供参考答案2:我认为是D。整句话的意思：风能是一种古老的可以（被循环利用）在将来再生的能量。还原定语从句，.....we may return from (this) energy ....供参考答案3:C 词组 类似turn to

这个解释是对的
