在这里must be 表示推测,所以反义疑问句应该是 he must be in his bedroom now ,isn't
he?
解释如下 My father must be in his office, isn't he?
must 的反意疑问句规则较多,本句中must表示猜测“一定,肯定”,反意疑问句的附加谓语不用must和need,而是在意义上和陈述句中谓语动词的时态保持一致,即must之后的动词be.类似的例如:He must be from the south, isn‘t he? 他肯定是南方人,是不是?
he asked me if i had seen the film ?
