反意疑问句一，定义：当我们陈述了一个事实，而又不是很有把握，就可以在陈述句后加一个简短问句，称为反意疑问句。
例如: She is a teacher, isn’t she?We are students, aren’t we?二，反义疑问句的结构结构一：前肯，+后否eg. He is a student, isn’t he?结构二：前否，+后肯eg. He isn’t a student, is he?三，反义疑问句的做题步骤{同学们看到反义疑问句时，一定要想到以下这两个步骤}1，判定。
判断用肯定还是否定。
（前面的句子中有否定词not, never, few, little, nothing的时候，后面用肯定：反之，则用否定）eg. He has never been to paris, has he ?She knows little English, does she?2，找动词。
(用于提问的动词有三种：be, do 和have。
其中be 动词包括am, is, are, was, were. Do包括do, does, did. Have包括have 和has，had.)eg. She is a doctor, isn’t she? (这里是be动词)She likes music, doesn’t she? (这里是一般性的行为动词，用do的各种形式来提问)Mr. Smith has bought many books, hasn’t he? (这里是have表示完成时态)注意：当看到have的时候。
同学们一定要注意，当have表示“有”和“吃”的意思时，我们不用have，而是用do的各种形式。
例如：She has a book, doesn’t she? (有一本书)You have a good friend, don’t you？(有一个好朋友)He usually has dinner with his parents, doesn’t he ?也就是说：当看到have+动词过去分词，表示完成时态的时候，用have或has 的形式提问。
当have表示“有”和“吃”的意思时，我们用do的各种形式提问。
