We interviewed the old lady,_____ had been killed in the air crash last week.
whose all children
all of whose children
有什么区别?

可以这么说,whose all children和all of whose children之间没有可比的.因为在英语中不会有whose all children这样的说法,或是词序.学英语是学一种语言,就像我们学汉语一样,最初都是模仿,所以要多读、多看,有许多东西——表达方式、词的用法、句子结构——都是一种语言习惯,现在我们没法,也不可能去追究是为什么.读书破万卷下笔如有神.学语言不是天天做题,而是天天读书.
新年快乐!
