has在这里做助动词,与does一样,如果has是实义动词的话,那么就用does,因为是反义疑问句,所以后面提问与前面主句意思相反,用hasn't

谓语动词时has been to ,时现在完成时，has 在此时是助动词，没有实际意思，所以用has,只有当它做“有”的意思时，后面才用助动词，再根据反义疑问句的回答模式，前肯，后否

前面半句用的时态是现在完成时，所以反问疑问句当然也用现在完成时：hasn't he

前面肯定，后面用否定

主句是肯定句，反问用否定，has been是现在完成时，has是助动词

反义疑问句

have been to固定词组。意思为去过。因为your father是三单。所以用has
