1 、have breakfast 是固定搭配,“吃早餐”的意思.
上述句子为一般疑问句.借助动词did 提前,真正的动词是have.
其陈述句：I had breakfast.
2 、Have you had your breakfast yet
Yes.Mom ( ) it for me.
A.was cooking
B.is cooking
C.will cook
D.cooked
Have you had your breakfast yet?- 你吃早餐了吗?（完成时态疑问句）
Yes.吃了.（表示已经吃过）
Mom cooked it for me.妈妈为我做的早餐.（是在你吃早餐前做的,所以用过去时态）
所以选择 D = cooked
3 、
did you have breakfast 语气上好像是不太关心到底吃了没,只是一种寒暄对话的感觉.吃或没吃对其根本没影响.
have you had breakfast?能感觉到提问人的关心,是其亲人亦或接下来要一起有什么活动的partner.完成时态嘛,考究的是对现在造成的影响或结果!
