have作为动词的反义疑问句：
①have to 的短语,且只充当一般动词的作用,助动词为do,does,和普通的一般疑问句没有任何差别,提问还是用do,does引导.
We have to finish it ,don't we?
②当用have,has做助动词的时候,疑问句才用它们引导,如：She has seen it,hasn't she?这里的助动词就是has
③当陈述部分有had better,或其中的have表示完成时态时,疑问句应用hadn’t等开头：You’d better get up early,hadn’t you?
④其他情况句中有have时疑问句应用don't等开头；如have表示“有”的时候,有两种形式：do或 have He has two sisters,doesn't he?=He has two sisters,hasn't he?
He doesn't have any sisters,does he?
⑤当must+have done表示对过去的情况进行推测（一般句中有明确的过去时间状语）,问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”；
如果强调动作的完成（一般没有明确的过去时间状语）,问句要用“haven't/hasn't+主语”.
She must have read the novel last week,didn't she?她上星期一定读了这本小说,是吗?You must have told her about it,haven't you?你一定把这事告诉她了,是吗?
