问题描述：
He has to walk to the station every day,hasn't he?为什么要该成He has to walk to the station every day,doesn't he?
为什么has不行?
答
因为这里的has不是实意动词
而真正的实意动词是walk
所以后面的提问要用does
答
has to表示不得不，谓语动词是walk
所以用does
答
这里has为实意动词，不是情态动词
答
一种是american english,另外一种是british english.其实两种都可以有。
答
用has的前提是它在句子中做助动词,而在这个句子中,has是实意动词,它的否定和疑问需要用到其助动词does.
所以反意疑问的时候要用does.
