The house of which the windows were broken was empty.

of which（定语） the windows（主语） were（系动词） broken （表语）谢谢！把of which改成where行吗？不可以。 可以改为whosewhose windows were broken为什么？where在引导的定语从句中作地点状语啊这是作定语的， 表示“窗和房子的关系”， 即【房子的窗户】， 明白？where 只能作状语那么这句句子用where对吗？If you are traveling to a place where the custom and culture are really foreign to you own，please do as Romans do.这里可以
