your father has been to GuangZhou twice,( has he,hasn't he,doesn't he,isn't he
为什么选b

反义疑问句中的助动词与主句中的助动词一致,主句中可以看出助动词是表示现在完成式的have,所以疑问句中也用have; 另外如果主句是肯定,则疑问用否定,因此选 hasn't he

hasn't he 前面的has是助动词 有助动词的情况下 后面的反义疑问句用助动词引导 且应该用反义 初二知识

反义疑问句，否定在助动词has上面

hasn't he

has没有实际意义，是助动词，所以不选C.D.本句话是肯定的意思：你的爸爸去过广州两次。前肯后否。所以用hasn`t
