当陈述句中含must的时如何变反意疑句
陈述句部分含有表示“禁止”的mustn’t 时，简略问句部分用must；含表示“必须，必要”的must 时，简略问句用needn’t；所含must 表示推测“想必，一定”时，若对现在的推测，must be 后，用isn’t 或aren’t，must do 后，用don’t 或doesn’t，若是对过去的推测，“must have+过去分词”后，一般用haven’t 或hasn’t，但当有 yesterday, last night 之类的表示明确过去时间的状语时，就用didn’t。

你记住，must反义疑问句就三种可能：①must②needn't③变换句式下面来讲一讲他们分别的用法，一般考试就这三种可能！1、mustn't→mustmustn't在陈述句中的意思一般是不允许，禁止，所以他的反义疑问句用must或may例：You mustn't smoke here, must you?或may you?2、必须→needn't当must在陈述句中作“必须”解时，它的反义疑问句就变成needn't例：You must go now ,needn't you?3、变换句式在must表示推测，做“一定，准是”，简单的说就是must用于虚拟语气时像数学一样我们引入一个“常量”——I am sure that下面就能你那句话作为例子，我们变换一下。
He must have come yesterday. 变换句式作I am sure that he came yesterday. 好我们应该分清，反义疑问句问的应该是I am sure that 后面的从句所以，按照一般反义疑问句的规则得出结果I am sure that he came yesterday, didn't he?最后再把句子还原He must have come yesterday，didn't he?此题解答完毕。

must在反义疑问句中的用法
must在反义疑问句中的用法好啦，今天咱们来聊聊“must”在反义疑问句中的用法。
反义疑问句，听起来就有点拗口，但其实挺简单的。
想象一下，你在和朋友聊天，突然冒出一句：“你肯定得去参加那个派对，必须的，对吧？”这句子就用到了“must”，而且用了反义疑问句的形式。
你可以感受到那种期待，真心希望对方也认同你的观点。
咱们得明白“must”这个词的意思。
它通常表示一种强烈的建议、必要性或者是肯定的推测。
比如说，看到朋友半夜还在加班，你就会说：“你必须早点回家休息啊！”这不是开玩笑，而是关心。
这时候，若你加上反义疑问句，就变得有趣多了。
你可以接着问：“你必须早点回家休息啊，不能不回吧？”这下就让对方有机会表达自己的看法了。
反义疑问句的魅力就在于它能让对话更有互动性。
你发出一个强烈的建议，然后再用反义疑问句给对方一个发言的机会。
就像在打乒乓球，你发球，对方接球，这样的对话就生动多了。
想象一下，你跟朋友讨论周末的计划：“我们周末肯定得去爬山，必须得去，难道不是吗？”这里的“难道不是吗”就是反义疑问句，让对方也参与进来。
可能他会说：“当然可以啊，不过我更想去海边。
”这一下就把话题推向了另一个方向。
有趣的是，反义疑问句常常能透露出说话者的态度。
比如说，如果你说：“你一定得试试这个新餐厅，真不错，得吧？”听起来就很兴奋，像是在给对方安利。
如果你说：“你必须得试试这个新餐厅，不然你会后悔的，对吗？”这就带了一点小小的威胁，仿佛不试就会错过什么大事一样。
咱们再看看不同场合下的用法。
想象你跟朋友在逛街，你看中了一件衣服：“这件衣服看起来真不错，你得买，必须的，对吧？”这时候，反义疑问句不仅能让你表达自己对衣服的喜欢，也能引导对方的选择。
毕竟，大家都喜欢被支持和鼓励。
反义疑问句还能带出一种玩笑的语气。
比如，你和朋友一起看电影，看到一个老掉牙的剧情，你就可以说：“这个剧情真是烂透了，肯定得让人笑死，不是吗？”这时候，你的语气是轻松的，带着调侃的意味，显得亲切又幽默。

must反义疑问句的回答口诀
must反义疑问句的回答口诀1. Must的基本理解1.1 大家好，今天咱们来聊聊“must”这个词。
别小看它，其实它是个小巨人！在英语中，must通常表示“必须”或者“一定要”，它给人的感觉就像是一个不容置疑的命令，嘿，你得去做哦！你想啊，这种词用得好，简直是信心满满的代名词。
1.2 不过，作为小巨人的“反义疑问句”，它可就有点意思了。
比如说，你可能听过这样一句：“You must be tired, mustn't you?” 这句话意思是“你一定累了，对吧？”这可是一门艺术，轻松带着点小调侃，简直是社交场合的必备技能呀！2. 反义疑问句的魅力2.1 首先，反义疑问句的魅力在于，它能让对话更有趣。
你想啊，要是直接问“你累了吗？”多没劲啊！而说“你一定累了吧？”就多了些温暖的关心和一点儿调侃，感觉一下子拉近了距离，心里暖洋洋的。
2.2 这里面还有一个技巧：反义疑问句的回答一般会跟上一个肯定的前提。
如果你问“You must be happy, mustn't you?”，那基本上可以肯定，回答的人会说“Yeah, I am!” 这就是个正循环，大家都开心，气氛也轻松。
3. 使用反义疑问句的场合3.1 反义疑问句可以用在很多场合，朋友之间的闲聊、职场的交流，甚至是家庭聚会。
比如说，家里有小孩，你跟他玩游戏时说：“You must have had fun, mustn't you?” 这不仅能鼓励小朋友，还能让气氛更加融洽，简直是一举两得！。
3.2 当然，别忘了，反义疑问句还可以加点幽默感。
比如说，在某个聚会上，你看到朋友刚吃完一大盘子炸鸡，就可以问：“You must be full, mustn't you?”这时，他可能会哈哈大笑，心里想“哪里够呢？我还想再来一盘！”这种小互动，总是让人觉得暖心又有趣。
4. 如何正确使用反义疑问句4.1 说了这么多，咱们再来看看怎么正确使用反义疑问句。
Must的反意疑问句
4）当must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（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（无过去时间状语），反意疑问句部分要 用“haven’t / hasn’t + 主语”。

反意疑问句中含有Must的情况主要有以下几种：
1）作为情态动词表“必须”，这时反意疑问句直接用mustn’t/needn't
2)当must表示推测时又分以下几种情况：
a：对现在事实的推测，反意疑问句与must后面的动词呼应，如:
You must be joking, aren’t you?
b:对过去事实的推测，表示动作的时候用did 当助动词，表示状态时用was，如：Mr Green must have been punished for his being rude at the meeting，didn‘t he ?(格林先生一定因为昨天在会上鲁莽的行为被处罚了，是吗？）被处罚表示一个动作She must have been a policeman ,wasn't she ?（她过去一定是个警察，是吗？）是警察表示一种状态
对现在情况的推测，问句部分用主动词（do, be)一般现在时的适当形式。
若是现在进行时，问句部分用现在进行时的适当形式表示。
若是there be结构，问句用isn't/aren't there。
如：
1)He must be there, isn’t he?
2)He must have a big family, doesn’t he?
3)He must be waiting outside, isn’t he?
4)There must be some students in the room, aren’t there?
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?
若是被动，应按被动结构来处理。
如：
1)The room must have been c leaned yesterday, wasn’t it?
2)The room must have been cleaned, hasn’t it?
若句中有表示过去完成时的时间状语，问句部分应用hadn't.如:
They must have learnt 5000 English words by the end of last term, hadn’t they?
(本题中must表推测，如果将它去掉，还原为真实句就是They had learnt 5000 English words by the end of last term.因此，反意问句是hadn't）。
