---Good morning. I’ve got an appointment with Mr Smith in his office.
---Morning. You ________ be Mr Jones. This way, please.

B．must

C．should

D．may

Answer 1

B

試題分析：句意：早上好。我和Smith 先生約好了在辦公室找他。早上好，你一定是Jones 先生，這邊請。本題考查情態動詞表推測的用法。can 可能，常用于否定句或疑問句；must 一定，準是，只用于肯定句；should 應該；may 可能，用于否定句或疑問句中，語氣較弱。根據題意，選B。
