这个要看例句了 其实很多时候都可以通用的 但是要是有固定搭配的话就另当别论了 像prefer to do ——rather than do 就是固定搭配 下面是例子 你可以自己体味一下 1.adv. 代替; 顶替; 更换 If you cannot go,he'll go instead of you. 如果你不能去,他愿替你去. If there is no coal,oil can be used instead. 如果没有煤,可以用石油来代替. 2.(要)…而不…,与其…倒不如… We'll have the meeting in the classroom rather than in the auditorium. 我们与其在教室里开会,不如在礼堂开会. 宁可,宁愿 Rather than being punished,he should be rewarded. 他该受奖励而不应该受惩罚
