Question

WHOSE BAG IS IT 为什么不 whose bag it is

Answer 1

WHOSE BAG IS IT 为什么不 whose bag it is
这是特殊疑问句的句子结构的问题。
英语语法规定，特殊疑问句句子结构是：
1、特殊疑问词 + 助动词 + 主语 + 实义动词 + 其他 ？
What can I do for you today?
2、特殊疑问词 + 谓语动词（组合） + 主语 + 其他 ？
What is your name, please?
3、特殊疑问词（主语） + 助动词+ 实义动词 + 其他 ？
Who will go to Guangzhong with the manager by plane tomorrow?
What has been offered to the poor homeless children for the coming winter?
4、特殊疑问词（主语） +谓语动词（组合） + 其他 ？
Who is the man under the big tree?
What must be finished first before we go to picnic two days later?

而 whose bag is it ？符合上边的第二条
whose bag是特殊疑问词， is 是谓语动词（组合），it是主语。
所以用whose bag is it ？，而不是whose bag it is？
