英语have been doing反意疑问句
You must have been playing tennis at the time,
反意疑问句怎么问?
句中有“have been doing"，和“at the tiem"，不是应该用weren't

做反义疑问句的时候首先要搞清楚助动词是哪一个
You must have been playing tennis at the time, _? 这句话中have做助动词引导现在完成进行时故应该是
You must have been playing tennis at the time , haven't you ?
She must have a kind mother,_?这句话中must表示推测,而不是表“必须”,反意疑问句应该提取后面的助动词 have做的是实意动词表示“有”的意思其助动词应该是do
因为是第三人称单数所以应该是She must have a kind mother,doesn't she?
