反义疑问句你知道吧?前面的谓语动词是肯定,后面就是否定.前面是否定,后面就是肯定.
因为第一句的谓语是must,但是后面填mustn’t的话太过强硬化（会变成不许）,于是yesterday是关键的时态词语,过去时用会didn’t.
第2句谓语也是must,同样的解释,have表示一般现在时,he是第三人称单数后面填hasn't.
He must have eaten too much yeserday,()?在线等候!
He must have eaten too much yeserday,()?在线等候!
He must have eaten too much yeserday,(didn't he )?
He must have finish it,(hasn't he )?
括号里为什么要这样填?
He must have eaten too much yeserday,(didn't he )?
He must have finish it,(hasn't he )?
括号里为什么要这样填?
