what when how who where ...开头的特殊疑问句,在提问的时候,
一般来说,一般现在时,一般过去时句子的行为动词要使用助动词do(does,did）
例：What subjects does he study in the university?
When did you go to school yesterday?
但是,在正在进行时,一般将来时,就不用 do(does,did）,因为要用助动词：be/shall/will
例：What are you reading now?
When will you go to see a film?
或者,是动词BE句子不用do(does,did）
例：Who is your English teacher?

助动词，帮助句子构成疑问句哦

这个地方的do,跟这个句子是类似的，Do his parents let him watch tv? 构成疑问句
对于How often 可以直接无视。
是必须要的。

是助动词哦！
