问题补充：

The question of drug-taking is bound to (一定要) at the next conference.

A. be come up

B. come up

C. come up with

D. be coming up

答案：

A. be come up

(答案→)B. come up

C. come up with

D. be coming up

解析： 考察固定搭配。固定词组be bound to do sth一定会做某事；come up出现，这个短语没有被动语态。Come up with提出，想出。如果选C项，要使用被动语态。句义：吸毒这个问题在下次的会议上一定出现。故B正确。
