用英语问：你吃早饭了么？能说have you eat lunch? 这是完成时么？不对应怎样

早餐是breakfast
Have you had breakfast? 你吃早饭了吗?
如果没有，就回答:I haven't had yet.
简单地说I haven't.也行.

Have you had your breakfast

No, I haven't

一般用：Did you have lunch?吃饭不是说eat lunch,而是have lunch。实在要用完成时就说：Have you had lunch?

回答：No i didn't. (No I have not.)

是完成时,但是写错了,要写过去分词
即Have you eaten breakfast?
回答可以说
No,I haven't或者I haven't eaten it yet
不能说I don't have

楼上几位说的had代替eaten也可以
