what kind of noodles would you like 为什么和疑问句结构不一样呢what后面不应该是助动词吗

这是很正常的【特殊疑问句结构】.
当特殊疑问词又修饰后面的名词短语时,应该先写出被修饰短语,然后,再写出其他部分.
【What 】【kind of noodles】 would you like ?
What type of computer would you like to have?
当然,还有你所说的那种形式——先接【助动词、情态动词、be动词】：
Which would you like to have, this kind of noodles or that one?
What should you do to realise your dream?
What is your favourite food?
看来,还是应该全面地了解知识才对.
祝你开心如意!O(∩_∩)O~~
