这是must have done 的 反义疑问句
这是对已发生的过去情况的推测.
一般规律是若陈述句谓语部分有“must have done”,而且有表示过去的时间状语,问句部分用didn't；如：
1)They must have gone there last night,didn't they?
若没有表示过去的时间状语,问句部分用haven't或hasn't.
如：2)They must have arrived by now,haven't they?（根据by now来判断）
3)They must have been to the Great Wall,haven't they?
