我举几个例子,你就明白了
He goes to school by bus everyday. Does he go to school by bus everyday?
He walks to the supermarket. Does he walk to the supermarket?
He bought some eggs. Did he buy any eggs?
He came late. Did he come late?
He is an engineer. Is he an engineer?
He was a teacher last year. Was he a teacher last year?
He is handsome. Is he handsome?
你看,go walk buy come都是一类动词,提问都用do,或者does,或者did,而本身原句里有be动词,也就是am is are was were时,提问就用相应的be。本回答被提问者采纳
