文档介绍：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}
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?
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。
