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。
如：
You mustn’t walk on grass, must you? 你不得在草地上行走，好吗？
You must go home right now, needn’t you? 你必须马上回家，对不对？
He must be mad, isn’t he? 他一定是疯了，是不是？
You must be tired, aren’t you? 你一定累了，对不对？
He must know her, doesn’t he? 他一定认识她，是吗？
You must have read it, haven’t you? 你一定读过它，是吗？
You must have seen t hat film last year, didn’t you? 去年你一定看过那部电影，是不是？。

must 的三种反义疑问句
must 的三种反义疑问句既然多数人感到麻烦我就来讲一讲must反义疑问句的用法。
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。

情态动词+动词完成时,即情态动词+have+done.表示对过去的行为或动作进行推测,评论或者判断.
1. must have done.
表示对过去某事的肯定猜测，其否定或疑问形式都用can/could来表示。
例如：Since the road is wet, it must have rained last night.
2；当然对现在发生或者将来发生的事情，要用must do表示猜测，否定为can’t do He must understand that we mean business.
You must be hungry after a long walk.
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）。
