关于不定冠词a的问题和第三人称单数的疑问
1.He has a headache
He has measles
为什么后面一句不需要加a呢
Does he have a stomach ache?
No,he doesn't have a stomach ache.
He has a headache.
为什么前面两句have不需要变成has?他们也是单数第三人称啊?

1)a 在数量上表是 “一”,而measles 已经复数形式,所以前面不能再用a了.
2)疑问句要用助动词do,而与主语一致搭配的任务就落实在助动词身上,你看那两个句子中的助动词的形式都是does,就是为了与单数第三人称的主语he搭配.助动词搭配了就够了.
在一般疑问句中要用原形了
headache 是可数名词,所以用冠词a
measles是不可数名词,所以不能用冠词a或者an
Does he have a stomach ache?
因为句子里有助动词do, does是do的单三形式,后面要用动词原形
