25. 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

C. referred to; be made

D. referred to; was made

解析： 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原形虚拟。
