反意疑问句

一、基本用法与结构

反意疑问句由"陈述句+简单疑问句"两部分组成，第一部分提出一种看法，第二部分用来质疑或表示证实。陈述部分与疑问部分的动词时态和动词性质应保持一致，而且肯定和否定形式彼此相反，即陈述部分为肯定式时，疑问部分用否定式，陈述部分为否定式时，疑问部分用肯定式： 如：He likes English, doesn't he? 他喜欢英语，不是吗？

He doesn't like English, does he? 他不喜欢英语，是吗？

二、反意疑问句的用法：

2. He doesn't like ice cream, does he? 2. 陈述句中的主语是名词，反意疑问句中用相应的代词来代替陈述句中的主语。

1）当主语是someone, somebody, anybody, anyone, everybody, everyone, nobody, no one等不定代词时， 反意疑问句中的代词用they或者he.

2）当主语是this, that, something, nothing, anything, 不定式，动名词，或从句时，反意疑问句中的代词用it 1. His father can't name the plant, can he?

2）作"必须"讲时，用 mustn't / needn't
