---Good morning. I’ve got an appointment with Mr Smith in his office.
---Morning. You ________ be Mr Jones. This way, please.
A．can
B．must
C．should
D．may

答案：B
题目分析：句意：早上好。我和Smith 先生约好了在办公室找他。早上好，你一定是Jones 先生，这边请。本题考查情态动词表推测的用法。can 可能，常用于否定句或疑问句；must 一定，准是，只用于肯定句；should 应该；may 可能，用于否定句或疑问句中，语气较弱。根据题意，选B。
