试题分析:考查情态动词辨析。Can’t 不能够;不可能;mustn’t禁止,千万不能;needn’t不必;shouldn’t不应该;句意:你能留下来吃晚饭吗?—对不起,我不能留下来。我在网上买的东西今天下午就要送到我家里了。故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
