一、概念
反意疑问句是附加在陈述句之后，对陈述句所表示的事实或观点提出疑问的句子.附加疑问实际上是一种简略的一般疑问句。
二、相关知识点精讲
1.反意疑问句的结构:陈述句(主语+谓语……)，+助动词/情态动词/be动词+主语(代词形式)?
说明:陈述句部分如果是肯定句，反意疑问句，疑问句部分的助动词/情态动词/be动词+not (否定提问);如果陈述句部分是否定句，反意疑问句，疑问句部分用肯定式提问。
例句:
He is your teacher， isn’t he ?
People shouldn’t drop litter on the pavements， should they ?
You found the key in the bedroom， didn’t you ?
They have a house in town， haven’t they ?/don’t they ?
The boy has to clean his room， doesn’t he ?
I am right， aren’t I ?
They’d rather go by bus， wouldn’t they ?
You’d better change your wet skirt， hadn’t you ?
He’d like to join our discussion， wouldn’t he ?
She ought to see a doctor at once， shouldn’t she ? / oughtn’t she ?
I wish to say a few words， may I ?
That’s nice， isn’t it ?
This is the place， isn’t it ?
Everybody knows the answer， don’t they ?
Nothing is serious， isn’t it?
There wasn’t enough time at that moment， was there ?
There used to a tower here， usedn’t there? / didn’t there ?
What you need is more practice， isn’t it ?
2.某些特殊句型的反意疑问句:
1)祈使句的反意疑问句:
表示肯定意义的祈使句，即表示“请求，提示”它的反意疑问句用will you 表达:有时也可以用won’t you 表示。
Go home now， will you ?
Close the window， please， will you ?
否定祈使句:以Don’t开始的祈使句:表示“不要……”，用will you 提问:
Don’t be late again， will you ?
Don’t forget to pay your income tax， will you ?
Let’s引导的祈使句表示“建议”，反意疑问句部分是:shall we ?
Let’s go for a walk， shall we ?
Let’s have a rest now， shall we ?
Let me 或 Let us引导的祈使句表示“请求”，反意疑问句部分为will you:
Let me have a try， will you ?
Let us help， will you ?
2) 感叹句的`反意疑问句:一律用否定式提问。
What a clever boy， isn’t he ?
What a lovely day， isn’t it?
3) 陈述句含有情态动词must有两种情况:
must表示“必须”，反意疑问句部分为mustn’t…? / needn’t…?
He must study hard at English， mustn’t he? / needn’t he?
You must go home now， needn’t you? / mustn’t you?
We mustn’t be late， must we ?
Must表示推测:“一定，肯定” 反意疑问句部分与must后面的动词呼应
You must be joking， aren’t you?
He must be ill， isn’t he ?
注意:用must对过去的动作推测时，反意疑问句部分的助动词用did或have， 而对过去的状态推测，反意疑问句部分的be动词用was:
She must have finished her work， hasn’t she ? / didn’t she ?
Jack must have arrived here yesterday， didn’t he ?
He must have been a policeman， wasn’t he ?
4) 陈述句中有否定副词:hardly; never; seldom; little; few; nowhere; nothing等词，反意疑问句部分用肯定提问:
Frank hardly goes to parties， does he ?
He has few friends， has he ?
5)复合句的反意疑问句:大多数复合句的反意疑问句都对主句提问:
He was punished because he violated the regulation， wasn’t he?
You never told me that you had been ill， did you ?
注意:I don’t think/suppose/believe/imagine 引导的宾语从句，这种宾语从句的反意疑问句应与从句的主语，谓语部分一致，而且用肯定式的提问。
I don’t suppose anyone will volunteer， will they ?
I don’t believe she has done it， has she ?
I think he will come. won’t he?
