Answer 1

does 这里是“助动词”,所谓“助动词”是帮助主要动词（这时的主要动词是行为动词,不包括be动词）构成：否定、疑问和时态等.最常用的助动词是do 和其各种变化形式如does,did；还有will,have/has等.
He likes music.
He doesn't like music.否定
Does he like music?疑问
What music does he like?疑问
Did he go to the park yesterday?疑问,过去式
He will go to the park.(will 是助动词）
但是 He is tall.
He isn't tall.
Is he tall?
