  •   must的反意疑问句有点难哟,不过也有定的规律可用: 1。当陈述句谓语动词是:must+have+done时,如果是对过去某种情况的推测,且句中有过去的时间状语时,反意疑问句根据动词用:didn't/wasn't/weren't+主语。eg。
      : (1)You must have read the story last term,didn't you? (2)He must have met her yesterday,didn't he? 2。当陈述句谓语动词是:must+have+done(过去分词)时,如果只是强调动作的完成情况,反意疑问句用:haven't/hasn't+主语。
      eg。: (1)She must have arrived there,hasn't she? (2)You must have seen the film,haven't you? 3。当陈述句谓语动词是:must+do(动词原形)时,是最为复杂的,看下面的例句: (1)You must see the doctor,needn't you? 表示“(主观上)必须”,其疑问部分用needn't(不必),如: We must go at once, needn't we? 我们必须立刻走,是吗? (2)You mustn't do that again,must you? 表示“应该/不应该”或"禁止",其疑问部分用mustn't(不应该)/must(应该),如: You must work hard next term, mustn't you ? 下学期你应该努力学习,对吗? 陈述部分含情态动词mustn't,表示禁止时,附加疑问部分就可以用must或may,如: We mustn't be late, must we?(may we?) 我们不可以迟到,是吗? (3)The food must be nice ,isn't it? 表示推测,其疑问部分必须与must 后面的主要动词相呼应。
      如: 1)对现在动作或存在的情况的推测: You must know the answer to the exercise ,don't you? 你一定知道这项练习的答案,是不是? That must be your bed, isn't it? 那一定是你的床,是吗? 总结: 1。
      陈述部分有must,且表示"必须"时,附加疑问句部分用mustn't。 2。如果表示"必要"则用needn't。 3。陈述部分中是mustn't表示"禁止"时,附加疑问句部分用must。 4。陈述部分中的must表示"一定"、"想必"等推测意义时,附加疑问句部分而是根据陈述部分的谓语动词或其助动词来定。
       练习: 推断用法:He must be lying to me。 推断用法反意疑问句:He must be lying to me, isn't he? 陈述用法:He is lying to me。 陈述用法反意疑问句:He is lying to me, isn't he? 推断用法:He must have been abroad。
       推断用法反意疑问句:He must have been abroad, hasn't he? 陈述用法:He has been abroad。 陈述用法反意疑问句:He has been abroad, hasn't he? 推断用法:He must have gone swimming yesterday。
       推断用法反意疑问句:He must have gone swimming yesterday, didn't he? 陈述用法:He went swimming yesterday。
       陈述用法反意疑问句:He went swimming yesterday, didn't he? He must be a visitor, isn't he?(对现在情况的推测) You must have seen him at his birthday party yesterday, didn't you?(对过去情况的推测,且句中有过去的时间状语) You must have seen him at his birthday party,haven't you?(强调动作的完成) 。

  •   当陈述句部分有情态动词must时,反意疑问部分有四种情况 (1)must表示“必须、禁止“时,反意疑问部分要用must (mustn’t) 。 例 You mustn’t stop your car here, must you? 你不能把车停在这地方,知道吗? (2)must表示“有必要”时,反意疑问句部分要用needn’t。
       例 They must finish the work today, needn’t they? 他们今天必须要完成这项工作,是吗? (3)当must用来表示对现在的情况进行“推测”时,反意疑问部分要根据must后面的动词采用相应的形式。
       例 He must be good at maths, isn’t he? 他数学一定学得很好,是吗? (4)当must用来表示对过去的情况进行“推测”(must + have done)时,如强调对过去情况的推测(一般句中有过去的时间状语),反意疑问句部分要用“didn’t + 主语”;如果强调动作的完成(一般没有过去时间状语),反意疑问句部分要用“haven’t / hasn’t + 主语”。
       例 She must have read the novel last week, didn’t she? 她上星期一定读了这本小说了,是吗? You must have told her about it, haven’t you? 你一定把这事告诉她了,是吗? 。
