you had nothing for breakfast , did you ? -{事实上没吃，怎么说}

No,I didn't.

no,i didn't

--You had nothing for breakfast, did you?
--No, I didn't.

--You had had nothing for breakfast, had you?
--No, I hadn't.

以上都表示没吃，我记着是。
有错请更正:)

NO,I didn't.意思是说:是的,我什么也没吃.
问句的意思是:你早餐什么也没吃,你是没吃吗?
答:是的,我什么都没吃~~

事实上没吃
As a matter of fact,/In fact,/no, I didn't!

英文中的正，反意疑问，不管其句形均以实际情况回答yes or no
