反意疑问句
反义疑问句遵循这样一个原则，前肯定后否定，前否定后肯定。
1. 肯定陈述句+否定提问 如：Lily is a student, isn't she?
2. 否定陈述句+肯定提问 如：She doesn't come from China, does she?
3. 提问部分用代词而不用名词 如：Lily is a student, isn't she?
4. 陈述句中含有否定意义的词 如：little, few, never, nothing, hardly等，其反意疑问句用肯定式（对于第四点大家不要忽视，尤其是列举的这几个词，出题的时候经常遇到，对于下面的两个例子大家要仔细看一下，要把这个知识点彻底搞懂）。
如：He knows little English, does he? 他一点也不懂英语，不是吗？
They hardly understood it, did they? 他们几乎不明白，不是吗？
5. 反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时，陈述部分要视为肯定含义，问句部分用否定形式。
our father is unhappy, isn't he?
The man is dishonest, isn't he?
It is impossible to learn English without remembering more words, isn't it?
