单选题 Do you still remember ______ to our president when you visited our school last term?
A. to be introduced B. being introduced
C. introduced D. to have been introduced

【正确答案】 B

【答案解析】根据句意，“你还记得上学期你到我们学校时被介绍给我们校长的事吗?”应选 V-ing形式作remember的宾语，表示记得做过的事。故只有[B]正确。remember to do sth．表示“记住要作某事”(事还未作)，如Remember to turn off the light when you leave the classroom after school．
