问题补充：

Mr Smith suggested the problem worth paying attention to at the meeting.

A. should discuss

B. was discussed

C. being discussed

D. be discussed

答案：

A. should discuss

B. was discussed

C. being discussed

(答案→)D. be discussed

解析：suggest作“表明，暗示”讲，后面的宾语从句用陈述语气；suggest意为“建议”，后接的宾语从句中用“should + 动词”，should可以省略。the problem与discuss之间是被动关系，因此用被动语态。句意为：史密斯先生建议值得注意的问题在会上讨论。
