　　1. Everybody is here, aren't they/isn't he? (指人的不定代词作主语，简略 问句一般用they, 也可用he)
　　2. I don't think he is a doctor, is he? (陈述句是转移否定，反意疑问句的主语和谓语必须和从句一致。)
　　3. Open your books, would you/won't you? (陈述句对第二人称的祈使句，简略问句可用will you? Won't you? Would you? Can you? 或can't you?)
　　4. Don't forget to write a letter to me, will you?(在否定祈使句中，只用will you?)
　　5. Let's go to the station shall we?(Let's 包括听话者，所以用shall we?)
　　6. Let us go for a walk, will you?/won't you?(Let us 不包括听话者，而是向听话者提出建议或要求。)
　　7. We must study all the subjects well, needn't we?(must在这里不表示&必须&，只表示&有必要&， 所以不重复must, 要用need.)
　　8. It must be Xiao Wang, isn't it?(must be在这里表示推测，要用be 的适当形式)
　　9. You must have seen the film &Shaolin Brothers&, haven't you?(当must+不定式的完成式表示对过去事情的推测时，用have。)
　　10. The boys mustn't play with fire, may they?(当must表示&禁止&时，反意问句要用may.)
　　11. He used to get up early, didn't he/ usedn't he?(当陈述句含有used to时，简略问句用did,也可重复used.)
　　12.We usually have breakfast at seven, don't we?(当have不作&有&解而用作行为动词时，简略问句用do 适当形式)
　　13. You had to do it well, didn't you?(陈述部分的谓语包含have to, has to, had to时，疑问部分要用do 的适当形式。)
　　14. Nothing can stop us now, can't it?(陈述部分用everything, nothing作主语时，疑问部分主语用it.)
　　15. I am a three-good student, aren't I?(陈述部分用I am 时，疑问部分用aren't I.)
　　16. There is something wrong with your TV set, isn't there?(陈述部分为there+be结构，疑问部分用ther,省略主语代词。)
　　17. I wish to go to the cinema, may I?(当陈述句是主语结构I wish, 用以征求对方意见，简略问句用may I.)
　　18. Tom has been reading novels, but he didn't read this afternoon, did he?(陈述句是并列句，简略问句的主谓语应和后一个分句一致。)
　　19. She dislikes smoking, doesn't she?(如果陈述部分里出现表示否定意义的某些词 如never, hardly, few, little,nothing,nobody等，简略问句要用肯定式;但是， 如果谓语是通过加前缀构成的否定词，简略问句用否定。)
　　20. That China is a great socialist country is well known, isn't it?(不定式短语，动名词短语或主语从句作主语，简略问句的主语用it.)
　　21. This is my pen, isn't it?(陈述部分的主语this ,that,简略问句用it:陈述部分的主语these, those,简略问句的主语用they.)
　　22.None of it is here, is it?(在&none of&&结构中，如of 后的名词或代词是单数，后面的主语也为单数，这种情况，主要由于of 后的名词或代词为不可数名词)
　　23. In our class each of the students passed the exam, didn't he/they?(陈述部分如是&each of &结构作主语，若强调个别，简略问句的主语用单数代词;若强调全体，简略问句用复数代词。)
