最基础的英语问题
I have had breakfast.怎么同时用have had
He has bought an car .这个句子用了has.
I have been to Switzerland.这个句子用了have.
那什么用has

have + 动词过去分词 = 现在完成时,表示一个动作发生在过去,到讲话时已经结束了.主语是第三人称单数的时候,have 自然要转变为 has .
I have had breakfast.have breakfast 是固定用法,即吃早饭,have作为动词,过去分词形式是 had ,套入公式即为 have had.
He has bought a car.bought 是 buy 的过去分词,has 是 have 的第三人称单数形式.
I have been to Switzerland.主语是 I ,所以要搭配 have .需要搭配 have 的,除了 I 外,还有 we 和 they ；需要搭配 has 的,有 he 、she、it.

用动词的适当形式填空。 1. I ______ (have,had) an English breakfast 英语HAVE HADyou would have had time for breakfast.If I had had I have already had breakfast.怎么改为否定句? 请问：I have had my breakfast he has had breakfast .has 与had I ( )an English class yesterday填had、have、has哪一个? 什么时候用have,had,has Have you had breakfast,Lily?No ,I didn't _____like eating an He has had some cabbage.(改为一般疑问句）I have had a haircut today. has,have,had用法 i have had an X-rey为什么have后面还要用had呢?i have an X-rey不行吗? 几个英语的问题```1.He usually _____(have,has)breakfast at home.2.Sh
