问一个英语问题，在一般疑问句中，何时用be动词提问？何时用助动词提问？

看陈述句，是be动词还是谓语动词，
例如I like playing table tennis.
提问What do you like?

I want to eat beef noodles.
对beef提问What kind of noodles do you want to eat?

又例如I am from China
提问Where are you from？
I come from China
Where do you come from?

句中有be 动词，情态动词，助动词（完成时态中的have /has /had ),变一般疑问句时直接把这些词提到句子前面，否则加助动词do /does(主语是第三人称单数一般现在时用does)/ did (一般过去时），原来的动词要还原
如：
He is a student -> Is he a student ?
She can sing . -> Can she sing ?
He has finished his homework . -> Has he finished his homework ?
He has lunch at home . -> Does he have lunch at home?

原句中有be动词用be动词，否则用助动词。be动词适用的时态是进行时。
