he has three classes every day 对划线部分提问,画线是three

问题描述:

he has three classes every day 对划线部分提问,画线是three

How many classes has he every day?

应该是How many classes has he every day?

How many classes does he have every day?
因为classes是可数名词,对其数量提问应用how many.
has在句中是动词,改成疑问句应以助动词does修饰之,has在助动词does后面时就应变为原型have.
相信我没错的.
