An exhibition of paintings at the museum next week.

A. is being held

B. is to be held

C. is holding

D. will hold

答案：

A. is being held

(答案→)B. is to be held

C. is holding

D. will hold

解析：be to+动词原形，表示“按计划或安排要做的事”，由题可知，exhibition和hold是被动关系，故此结构应用被动形式：be to be done.本题大意，油画展在下周在博物馆举行。

考查点：一般将来时的用法。
