    what when how who where ...開頭的特殊疑問句,在提問的時候,
    一般來說,一般現(xiàn)在時,一般過去時句子的行為動詞要使用助動詞do(does,did)
    例:What subjects does he study in the university?
    When did you go to school yesterday?
    但是,在正在進行時,一般將來時,就不用 do(does,did),因為要用助動詞:be/shall/will
    例:What are you reading now?
    When will you go to see a film?
    或者,是動詞BE句子不用do(does,did)
    例:Who is your English teacher?
    我來回答
