疑问代词和疑问形容词的问题,
疑问代词和疑问形容词在有系统词BE中区别是不是：
疑问代词：后面接的是BE 比如：which is your book?
疑问形容词：后面接名词：which book is yours?还有是不是what,who,which都这么用,那么
下面这2个句子对吗：
what colour is your car?
what is your car colour?

Answer 1

其实你的问题就是疑问词的用法
疑问词在句子里可以做什么成分的问题
疑问词分为疑问代词（who,whom,what,which,whose）和疑问副词（when,where,how,why ）
which is your book?which是疑问代词作主语
which book is yours?which是疑问代词作定语,book 是主语
what colour is your car?what是疑问代词作定语 colour是主语
what is your car colour?改成what is the colour of your car?更好点
从语法上来讲都没错
但最好的说法还是what colour is your car?是问颜色的固定表达方式
