今天老师讲了情态动词
the book must be Mike's ,there is his name on it
这里面的must 不能用may 么、是重点强调还是就是不能换
the boy can't be Mike ,he's gone to Japan
这里面的CAN'T不能换成MUSTN'T么? 求速度解释

情态动词表示推测,理论：（初中阶段）可能是……can/could be（一般用于疑问句）(一般只用can）可能是……may/might be（用于肯定句）,表示说话人没有充足的证据,不确定,一般出现I'm not sure./Not yet.之类的就选这个.一定是……must be,表示说话人有充足的证据,并且下文要拿出证据.不可能是……can't/couldn't be,同3,表示说话人有充足的证据,并且下文要拿出证据.（注意不是must的否定,must的否定mustn't只表示“禁止”的意思）可能不是……may not/might not be）,同2,表示说话人没有充足的证据,不确定,一般出现I'm not sure./Not yet.之类的就选这个.（但是很少出题）如果你耐心看懂以上理论,你就会发现,题1,由于后文有证据,所以要肯定的推测.题2,mustn't不能表示推测.
再问：谢谢十分清晰
