在反意疑问句中，简略问句的主语和谓语在人称和数方面要和前面的陈述句保持一致，但是，也有不少不一样的特殊情况，大致有25 种情况。
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?)
