这两个词没什么区别,都是引导定语从句,且在定语从句中充当地点状语.小地点则是where/at which,在……外面是where/out of which,在……上面是where/ on which,在……旁边是where/by which或near which. 其他,如在从句中作原因状语的why/ for which,作方式状语的 that/in which,作时间状语的when/at(in/on) which也都可以互换. 具体的你可以查询“定语从句”详细了解.
in which 前面要有noun 一般都是说 where 可是 用 in which 其实更正确 Remember that scene where Tim tells Frank about Romeo and juliet. Remember that scene in which Tim tells Frank about Romeo and Juliet.
