这是规律，要记牢
.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 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

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:

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?
反意疑问句前后两部分谓语应是，“肯定陈述＋否定疑问”或“否定陈述＋肯定疑问”
