关于there be 结构的用why引导的特殊疑问句

如果用why 对there be 结构提问？
比如说“为什么他们之间有很大区别？”是用why there are...还是why are there...提问？
在网上两种结构都有，有什么区别吗？

Answer 1

why (are there) many differences between them??书面语.

why there are..口语

what is your name?? 书面语

what your name is?? 口语

Answer 2

why are there.
因为这是一个特殊疑问句，就吧are提前，再加特殊疑问词why。
若是宾语从句，比如“she asked that why there are……”就用陈述语序。
