含有have的句子,变疑问句,什么时候用do 什么时候吧have放句首呢?
之前知道的是have当助动词时放到句首,当普通动词时用DO
那比如,“你吃过午饭了么?”为什么有2种提问呢,Did you have your lunch?Have you had your lunch?

答案
have当助动词时放到句首,当普通动词时用DO
Did you have your lunch?Have you had your lunch?这两个句子就是上面两种情况啊:
you had your lunch(have作普通动词,过去式)
you have had your lunch(have作助动词,完成时)
Did you have your lunch?Have you had your lunch?这两个句子就是上面两种情况啊:
you had your lunch(have作普通动词,过去式)
you have had your lunch(have作助动词,完成时)
