They work here, don’t they?
She was ill yesterday, wasn’t she?
2.陈述部分否定式 + 疑问部分肯定
You didn’t go, did you?
He can’t ride a bike, can he?

+主语（只能是）人称代词前肯后否前否后肯
3.附加问句和陈述句人称、时态一致
4.简短问句的否定形式，要用缩写形式，不能出现not，主语要用人称代词不能用名词. Her mother is a doctor , isn‘t she?
5.对反意疑问句的回答，是根据事实，而不是根据问题
的提法。 He isn‘t a doctor, is he ? (他不是医生，是吗？) Yes, he is . No, he isn't. 6. 陈述部分如果有否定意义的词，如：hardly（几乎不）, never（从不）, nothing, few, little, no, seldom（很少）， too…to（太…以至于不能） 等, 这时疑问部分要用肯定形式。
