句意：——我能用支票付账吗?——对不起,先生。
但这是我们酒店的管理规定,支付要用现金。
shall可以表示命令，警告，强制，或者指规则和法律要求做的事情。
本题正是考察了shall表示按照规则和法律要求做的事情。
故A正确。

句意：你或许是对的，但我还是要回去核对一下。
A. should应该；B. must 一定，必须；C. need需要；D. might或许。
本题主要考查情态动词表示推测的用法，由I’m going back to check anyway可知，我对此不确定。
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。
