英语语法中,一个副词常可拆成一个介词+名词/代词.work there; live there; stay there等都可以根据语境拆成:work in/at+n;live in/at+n;stay at/in+n如是定语从句:The city____he lives is very beautiful.空内可填where也可添in which所以说,象你提问的在定语从句中why与for which以及when与on/in which都是遵循这个道理的.也可互换.

用where的时候应该是This is the house where he live.

很简单，在定语从句中in which与where的意义完全相同。如果使用in which则不用在后面再使用介词，相反用where在后面可以使用介词。例如： This is the house where he live in. This is the house in which he live.
