反意疑问句由"陈述句 + 简短问句"构成，遵循"前肯后否、前否后肯"原则。
要点讲解
- 前肯后否：He is a student, isn't he? 他是学生，不是吗？
- 前否后肯：He isn't a student, is he? 他不是学生，是吗？
- 陈述句有 be/助动词/情态动词，反意部分用同一助动词：She can swim, can't she?
- 实义动词用 do/does/did：They like music, don't they?
- 反意部分的时态与人称与陈述句一致。
- 特殊：I am...→aren't I：I'm right, aren't I? 我对了，不是吗？
- 祈使句：Open the door, will you?；Let's go, shall we?；Let us go, will you?
- there be 句型：There is a book, isn't there?
- 含否定词（never, hardly, little, few, nothing, nobody）的陈述句按否定处理：He never comes late, does he?
- 回答反意疑问句按事实回答：—He isn't a teacher, is he? —Yes, he is.（不，他是）
- 陈述句含 must：must 表推测用 be 反问：He must be at home, isn't he?
经典例句
- You have finished your homework, haven't you?
你完成作业了，不是吗？ - She hardly ever goes out, does she?
她几乎从不出去，是吗？ - Nothing is impossible, is it?
没有什么是做不到的，不是吗？
易错提醒
- 含 never/hardly/little/few/nothing 的句子按否定处理，反意部分用肯定；回答按事实，Yes 后跟肯定事实。
