句意：——我能用支票付账吗?——对不起,先生。

由此可知，D项符合题意。
故选D项。
【点睛】can / could用于表推测的用法(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。
两者没有时间上的差别，只是could 比 can 更委婉，更不确定。
(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接 be doing 结构；对过去情况作推测，后接动词完成式。
二、 may / might用于表推测的用法表示推测，两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小。

英语情态动词题20套(带答案)及解析
A．shallB．must
C．canD．should
【答案】D
【解析】
【详解】
考查情态动词。句意：我仍然难以想象这样聪明的孩子竟然犯这样愚蠢的错误。should作为情态动词，可以用来表示意外、惊喜或者在说话人看来是不可思议的，常常译为"竟会"、"居然"，这么聪明的孩子竟然犯这样愚蠢的错误。表示意外，shall表示允诺，命令等，must表示必须，can表示能力及可能性。所以答案选D。
【答案】B
【解析】
试题分析：考查情态动词用法。Shouldn’t have done本不应该做某事，实际上却做了（虚拟语气）；couldn’t have done不可能做某事（对过去情况的推测）；needn’t have done本不需要做某事，实际上却做了（虚拟语气）；句意：我的姐姐昨天下午在街上遇见了他，所以他不可能去听了你的演讲。故B正确。
3. shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。如：Shall we begin our lesson? When shall he be able to leave the hospital?
4. shall用于第二、第三人称，表示说话人给对方命令、警告、允诺或威胁。如：You shall fail if you don't work harder.（警告）He shall have the book when I finish reading.（允诺）He shall be punished.（威胁）
