must have done的反义疑问句
反义疑问句详细讲解及习题及答案
反义疑问句一．句型解释反义疑问句(The Disjunctive Question)：即附加疑问句。
它表示提问人的看法,没有把握,需要对方证实。
反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，两部分的人称时态应保持一致。
1．陈述部分肯定式+疑问部分否定式2．陈述部分否定式+疑问部分肯定式She was ill yesterday, wasn’t she?You didn’t go, did you?二．特殊的句型1.祈使句。
祈使句后一般加上will you或won't you构成反意疑问句，用will you 多表示“请求”，用won't you 多表示提醒对方注意。
例如：Let引导的祈使句有两种情况：1) Let's...,后的反意疑问句用shall we或shan't we。
例如：Let's go home, shall we/ shan't we? 回家吧，好吗？2)Let us/me...后的反意疑问句用will you或won't you。
例如：Let me have a try, will you/won't you?3）祈使句都用will you 或won’t you2.当陈述部分含I think (believe, suppose...)that... 结构时，其反意疑问句须与从句的主、谓语保持一致，注意主句的主语必须是第一人称。
例如：I don't think he will come, will he?若是非第一人称，则与主句的主语相一致He thinks that she will come, doesn’t he?反意疑问句的陈述部分为I(We) don’t think(believe, suppose, consider)+ that从句时，从句为否定意义，问句部分的动词和主语仍与that从句保持一致且用肯定式。

2019年高考英语考点一遍过考点37 反义疑问句 含解析
考点37 反义疑问句高考频度：★★★★★高考对疑问句的考查主要是对反义疑问句的考查。
反义疑问句也叫附加疑问句，指的是在陈述句后面附加一个简短的一般疑问句，用于对陈述句所说的事实或观点提出疑问或表示证实。
陈述部分与附加部分的动词时态和动词性质应保持一致，但是肯定和否定形式却彼此相反，即陈述部分为肯定式时，疑问句部分用否定式；陈述部分为否定式时，附加部分用肯定式。
反义疑问句主要分以下各种情况：反意疑问句由两部分构成：前一部分用陈述句形式，后一部分是一个附加在前一部分上的简短问句。
陈述部分用肯定形式时，附加问句部分用否定形式，反之亦然。
附加问句部分的动词形式及主语由陈述句决定，而且主语必须是代词。
1. 陈述部分的主语是名词时，附加问句的主语用相应的人称代词。
Your parents had a long talk with you last night, didn’t they?2. 陈述部分主语是表示人的不定代词时，反意疑问句的主语侧重全部用they，侧重个体用he。
No one was there that day, was he/were they?3. 陈述部分主语是表示物的不定代词时，反意疑问句的主语用it。
Everything that he says is true, isn’t it?4. 陈述部分的主语是one时，反意疑问句的主语在正式的场合用one，在非正式场合用you。
One should be honest, shouldn’t one/you?5. 陈述部分主语是指示代词时，反意疑问句的主语要用it或they。
This is your car, isn’t it?Those are grapes, aren’t they?6. 陈述部分是there be结构时，反意疑问句仍用there。
There was a hospital here, wasn’t there?7. 陈述部分有表示推测的情态动词must时，反意疑问句的动词与must后的动词一致。
含有must的反义疑问句
含有must的反义疑问句
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若must表示“必须”或“有必要”，疑问部分用mustn’t或needn’t：
You must leave at once, mustn’t[needn’t] you? 你必须(有必要)马上离开，是吗?
但是若陈述部分有mustn’t表示禁止，疑问部分要must：
You mustn’t laugh, must you? 你不准笑，知道吗?
②若must表示推测，疑问部分不能用must，而应根据must后的动词结构采用相对应的动词形式：
He must be tired, isn’t he? 他一定累了，是吗?
③当must用来表示对现在的情况实行“推测”时，反意疑问部分要根据must后面的动词采用相对应的形式。
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实行“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？。

Must的反义疑问句
Must的反义疑问句：当陈述部分有情态动词must，问句有4种情况：（1）mustn't表示“禁止，不可，不必”时，附加问句通常要用must.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，附加问句通常要用needn't.They must finish the work today,needn't they?他们今天要完成这项工作，是吗？（3）当must用来表示对现在的情况进行推测时，问句通常要根据must后面的动词采用相应的形式。
He must be good at English,isn't he?他英语一定学得很好，是吗？（4）当must+have done表示对过去的情况进行推测（一般句中有明确的过去时间状语），问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”；如果强调动作的完成（一般没有明确的过去时间状语），问句要用“haven't/hasn't+主语”。
She must have read the novel last week,didn't she?她上星期一定读了这本小说，是吗？You must have told her about it,haven't you?你一定把这事告诉她了，是吗？need的反义疑问句：need的用法分为两种，一种是作为情态动词，一种是作为实义动词。
一般而言，need作为情态动词是在否定句（有时为疑问句中），此种情况在反义疑问句中通常为need I或needn't I，而当这句话是一句肯定句是，这里的need就作为实义动词，通常为do you或者是don't you就比如LZ说的句子I needn’t tell you the answer , need I ?这里need为情态动词，前面否定，后用need肯定You need to buy a better dictionary , don’t you ? 这里need为实义动词，前面肯定，所以后面用do的否定形式don't说起will，我不明白LZ是什么意思，与will有关的知识点整理在这里开头为Let's，后面一定用shall +we例：Let's go,shall we开头为Let us，后面一定用will you例：Let us go,will youthink, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时，视情况不同有两种不同的构成方式。
