反意疑问句
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?
