They suggested that the professor just now chairman of the meeting.

A. referring to; was made

B. referring to; be made

C. referred to; be made

D. referred to; was made

答案：

A. referring to; was made

B. referring to; be made

(答案→)C. referred to; be made

D. referred to; was made

解析：考查过去分词做定语和虚拟语气，refer to 与 professor 是动宾关系，所以用过去分词短语作定语；suggest表“建议”时，其后的宾语从句需用should do或动词原形表示虚拟。句意：他们建议刚刚被提到的教授被选为会议的主席。选C。
