反意疑问句综述
反意疑问句提出情况或看法，问对方同不同意，这种问句都由两部分组成，前一部分用陈述句的形式，后一部分是一个附着在前一部分上的简短问句。
1．一般情况下，如陈述句中含有助动词、情态动词或系动词be, 则在附加疑问句中应重复此助动词、情态动词或系动词be, 问句中的主语应与前面陈述句的主语同指一个(些)人或物。如：
He has finished his homework, hasn’t he?

You went home yesterday, didn’t you?
He likes playing basketball, doesn’t he?
3．如陈述句部分是 I 引导的主系表结构组成，附加疑问句部分的主语仍用第一人称单数，但谓语动词应用are的某种形式，一般不用am。如：

He is unfit for the job, isn’t he?
They discovered the secret, didn’t they?
It is unnecessary to write down all the words and phrases, isn’t it?

You ought to go there, oughtn’t you / shouldn’t you?
21．当陈述句部分含有情态动词need，dare 时，如果need, dare 为情态动词，则附加疑问句部分应重复此动词；如果是实意动词时，则要借助助动词do。如：
You dare to swim in the sea, don’t you?
He needn’t say sorry to me, need he?
22．当陈述句部分的谓语动词是have 时,附加疑问句部分应视不同情况采用不同形式。

He got up late, and he didn’t arrive on time, did he?
He has been wr iting letters all afternoon, and he should be finished, shouldn’t he?
18．当陈述句部分含有情态动词must，且表示推测意义“一定”、“想必”时，附加疑问句部分不能用must，而应根据陈述句部分的不定式结构采用相应的主动词或助动词。
(1) must be, must be doing 的反意问句用be not 的简略式。如：
He must be your friend, isn’t he?
They must be huntin g in the mountains, aren’t they?
(2) must +have done (been) 时，若动作在过去发生，用didn’t / wasn’t / weren’t；若动作延续但现在或已经完成，则用haven’t/ hasn’t。如：
He must have been a schoolboy when the war broke out, wasn’t he?
He must have joined the army when he left home, didn’t he?
Charlie must have worked here for 12 years, hasn’t he?
It’s one o’clock in the afternoon. They must have had lunch, haven’t they?
(3) must+动词原型（be,have除外)，用do / does / did not 的简略式，若must 后接表示 “有”的意思的have，则用have / has / had not 或 do / did/ dose not皆可。如：
He must feel terrible, doesn’t he?
You must have a lot of jewels, haven’t / don’t you?
19．当陈述句部分的must 表示“必须”时，附加疑问句部分用mustn’t; must 表示“有 必要”时，附加疑问句部分用needn’t；mustn’t 表示“禁止”时，附加疑问句部分一般用must,有时用may。如：
You must work hard next term, mustn’t you?
I must answer the letter, mustn’t it?
You must go back right now, needn’t you?
You mustn’t walk on grass, must you?
20．当陈述句部分含有情态动词ought to 时，附加疑问句部分可以用oughtn’t ( in British English)，也可以用shouldn’t(in American English)。如：
You ought to go there, oughtn’t you / shouldn’t you?
21．当陈述句部分含有情态动词need，dare 时，如果need, dare 为情态动词，则附加疑问句部分应重复此动词；如果是实意动词时，则要借助助动词do。如：
You dare to swim in the sea, don’t you?
He needn’t say sorry to me, need he?
22．当陈述句部分的谓语动词是have 时,附加疑问句部分应视不同情况采用不同形式。
(1) have意为“有”时，附加疑问句部分采用have或do 的形式。如：
She has two children, hasn’t she?/doesn’t she?
She doesn’t have a new bike, does she?
(2) 其他情况下，则应借助于do。如：
They had a meeting here yesterd

didn't he?
she must have finished reading the novel last night,【didn't she 】?
句中有时间的标志性短语 last night，时态就只能用一般过去时，不可以用完成时。【反义疑问句肯定要根据时态，所以是didn't she 】
陈述部分有must 的疑问句，疑问部分根据实际情况而定。
A．must表示“应该”，其疑问部分用mustn't（不应该），如：You must work hard next term, mustn't you ? 下学期你应该努力学习，对吗？
B．must表示“必须”，其疑问部分用needn't（不必），如：They must finish the work today, needn’t they? 他们今天必须要完成这项工作，是吗？
C．陈述部分含情态动词mustn't，表示禁止时，疑问部分就可以用must或may，如：You mustn’t stop your car here, must you? (may we?)你不能把车停在这地方，知道吗？
D．must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？
②对过去发生的动作或存在的情况的推测：
a 表示肯定推测
（一）句中陈述部分没有表示过去的时间状语，这时疑问部分中的动词就用现在完成时。（haven’t / hasn’t + 主语） You must have told her about it, haven’t you? 你一定把这事告诉她了，是
