there be 句型 的反意疑问句为什么

Question

如题所述

Answer 1

反意疑问句其实就是完整句子为避免重复的的省略，例如：

　　You are a student, aren't you? (=aren't you a student的省略)
　　He goes to school every day doesn't he? (=doesn't he goto school every day 的省略)

there be 是存在的固定格式，反意疑问句不能改变这种格式，所以要用 isn't there 或 aren't there，例如：

　　There is a boy in the room, isn't there?(=isn't there a boy in the room 的省略)
　　There are some boys in the room, aren't there? (=aren't there someboys in the room 的省略)

Answer 2

be not there？
