(一)陈述部分含有must/may/might的反意疑问句
1. 当 must 作“必须”讲时, 其反意疑问部分用 needn't;当含有 mustn't (不允许、禁止)时, 其反意疑问部分用 must/may。
You must go now, needn't you?
你现在必须走, 是吗?
You mustn't smoke here, must/may you?
你不可以在这里吸烟, 行吗?
2. 当 must/may/might 表示推测, 即 must 作“一定, 准是”讲, may/might 作“可能”讲时, 可首先将句子改为“I am sure/guess + that 从句”, 反意疑问部分的动词形式根据 be sure/guess 后的宾语从句的谓语动词形式确定。

→I am sure/guess that you are hungry now, aren't you?
→You must/may/might be hungry now, aren't you?

其反意疑问部分用 oughtn't 或 shouldn't 均可。

(四)陈述部分含有否定词或半否定词的反意疑问句
当陈述部分带有 seldom, hardly, scarcely, never, few, little, nothing, nobody 等否定词或半否定词时, 反意疑问部分的动词用肯定形式。

(六)陈述部分含有宾语从句的反意疑问句

He said that he would come to my birthday party, didn't he?
他说他要来参加我的生日聚会, 是吗?
2. 当陈述部分的主句谓语动词是 think, believe, suppose, guess, expect, imagine 等, 且主句主语为第一人称时, 反意疑问部分的主语和时态与宾语从句的主语和时态保持一致。注意否定的转移: 主句中的否定词实际上否定的是宾语从句。

(七)祈使句的反意疑问句
祈使句后的反意疑问部分不表示反意, 而表示一种语气。其结构为:
1. 否定祈使句, + will you?
2. 肯定祈使句, + will/won't you?
3. Let's..., + shall we?
4. Let us..., + will you?

Let's go out for a walk, shall we?我们出去散步, 好吗?
Let us go home now, will you?
现在, (您)让我们回家, 好吗?
(八)回答反意疑问句时应遵循的原则
1. 不管是陈述部分为否定, 还是反意疑问部分为否定, 回答时只按所提到的事情的实际情况来确定。如果事实是肯定的, 就用 yes 回答;事实是否定的, 就用 no 回答。如: 当对方问你 You aren't a teacher, are you? 或 You are a teacher, aren't you? 时, 你只要听懂 you 和 teacher 两个单词即可, 如果你是老师, 回答 Yes, I am. 否则, 回答 No, I am not.
2. 要么肯定到底, 要么否定到底, 不会出现类似于Yes, I don't. 或No, I do. 的形式。
