问题补充：

The president said that it was a great honor for him his country in the past two weeks.

A. to visit

B. to be visiting

C. to have visited

D. to have been visited

答案：

A. to visit

B. to be visiting

(答案→)C. to have visited

D. to have been visited

解析：句意：总统说在过去的两周里他参观了他的国家很荣幸。这里him与visit之间是主动关系，故排除D;选项A表示不定式的动作与谓语动词之后发生；选项B表示谓语动词的动作与不定式的动作同时发生；这里是谓语动词是过去式，参观发生在谓语动词之前，所以应该用不定式的完成时，故选C。
