反义疑问句
There be句型
There be 句型中,反义疑问部分必须为be 动词 + there There are some apples in the basket, aren't there? There isn't any milk left, is there?
must
.当陈述部分有情态动词must,问句有4种情况: (1)mustn't表示“禁止,不可,必须”时,附加问句通常要用must. You mustn't stop your car here,must you? 你不能把车停在这地方,知道吗? (2)must表示“有必要”时,附加问句通常要用needn't. They must finish the work today,needn't they? 他们今天要完成这项工作,是吗? (3)当must用来表示对现在的情况进行推测时,问句通常要根据must后面的动词采用相应的形式. He must be good at English,isn't he? 他英语一定学得很好,是吗?

句子中的动词是be ,must是副词,反义疑问句是对动词的反问。
