一、基本结构
前肯后否，前否后肯
陈述句 + 简短疑问句（两部分逗号隔开，句末用问号）
例：He is a student, isn't he?
He isn't late, is he?
二、核心口诀
be动词看be，有情用情态；
实义动词do/does/did替；
前有否定词，后句用肯定；
主语代词来代替，人称时态要统一。
三、分类讲解
1. 含be动词（am/is/are/was/were）
直接用be动词反问
- You are tired, aren't you?
- She was at home, wasn't she?
2. 含情态动词（can/must/should/will等）
直接用情态动词反问
- He can swim, can't he?
- We will go, won't we?
3. 实义动词（行为动词）
加助动词 do/does/did
- They like English, don't they?
- He plays basketball, doesn't he?
- You went there, didn't you?
四、必考否定词（前否后肯）
句子有这些词，视为否定句，后面用肯定：
never、hardly、seldom、little、few、no、none、nobody
例：He never lies, does he?
There is little water, is there?
五、中考特殊必考句型
1. Let's... , shall we? 咱们……好吗？
2. Let us... , will you? 请允许我们……好吗？
3. 祈使句：Open the door, will you?
4. There be句型：There is a book, isn't there?
5. I am... ：
I'm right, aren't I?
六、回答技巧（中考最爱考）
按事实回答，不管问句怎么问
- You aren't ill, are you?
没生病：Yes, I am. 不，我没事。
生病了：No, I'm not. 是的，我病了。
记住：事实肯定用Yes，事实否定用No。
