(3) 陈述部分为 there be 结构时，反义问句也用be (not) there. 除 there be 以外，此句型中的be可用live, appear, come, exist, happen, stand, lie, seem, remain, flow 等词代替，这时反义疑问部分用 doesn't / didn't there

这些词有no, seldom, hardly, never, rarely, few, little, nothing, nobody, etc.

You have a dictionary, haven't you? / don't you?
He hasn't a lot of time to spare, has he?
He doesn't have a lot of time to spare, does he?
当陈述部分have不表示“所有”,而表示其它含义时,反义疑问句用do的某种形式
