Whom do you like to be with?Who likes to be with you?
第一个谁是宾语所以是whom.第二句的谁是主语所以是who.为什么用to be with 而不直接写with .Whom do you likewith? Who likes with you?like = 喜欢be with XX = 和XX在一起like to be with XX 就是 喜欢和XX在一起like with 不是英文的语法，with 前面如果是动词，就是和某某一起做一件事情，比如：Whom do you swim with? Whom do you shop with?你和谁游泳？你和谁购物？所以如果按你的说法，Whom do you like with? 只能勉强翻译成 你和谁喜欢？所以这样说，英文和中文的语法都不对。
