试题分析：考查情态动词辨析。本题是强调句型的一个变式：It 情态动词 be…that/who…其它成分；本句是其特殊疑问句的形式。是对具体的发生进行的强调。句意：斯密斯先生总是很准时，怎么可能会乘坐飞机迟到呢？can可能；must一定，必须；may也许；need需要；根据句意说明A正确。 点评：情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。值的注意的是，中学阶段的情态动词常考额有13个，can-could may-might should-ought to had better will-would   need  have to .考生应注意对这13个情态动词的用法多总结，多运用。
