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， isnt he ？
People shouldnt drop litter on the pavements， should they ？
You found the key in the bedroom， didnt you ？
They have a house in town， havent they ？/dont they ？
The boy has to clean his room， doesnt he ？
I am right， arent I ？
Theyd rather go by bus， wouldnt they ？
Youd better change your wet skirt， hadnt you ？

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wont you 表示。
Go home now， will you ？
Close the window， please， will you ？
否定祈使句：以Dont开始的祈使句：表示不要，用will you 提问：
Dont be late again， will you ？
Dont forget to pay your income tax， will you ？
Lets引导的祈使句表示建议，反意疑问句部分是：shall we ？
Lets go for a walk， shall we ？
Lets 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， isnt he ？
What a lovely day， isnt 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mustnt？ / neednt？
He must study hard at English， mustnt he？ / neednt he？
You must go home now， neednt you？ / mustnt you？
We mustnt 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， arent you？
He must be ill， isnt 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， hasnt she ？ / didnt she ？
Jack must have arrived here yesterday， didnt he ？
He must have been a policeman， wasnt 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， wasnt he？
You never told me that you had been ill， did you ？
注意：I dont 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 dont suppose anyone will volunteer， will they ？
I dont believe she has done it， has she ？
I think he will come. wont he？
