He must have finished by the time tomorrow 反义疑问部分怎么问?用won't

这题答案hasn't he
对已发生的过去情况的推测,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；若没有表示过去的时间状语,问句部分用haven't或hasn't.如：1)They must have gone there last night,didn't they?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?

您好！应该是 mustn't he ? （ 是根据句子的时态结构） 望采纳 ！谢谢！

应该用，Would he
