A. recommended; added
B. recommended; adding
C. will be recommended ; added
D. to be recommended; to be added
答案：
(答案→)A. recommended; added
B. recommended; adding
C. will be recommended ; added
D. to be recommended; to be added
解析：：在第一空中，recommended 作the students（主语）的后置定语,即“被推荐的学生”， 第二空是 have sth done的结构；B选项都错了，而 C中的will be recommended是错误的， 因为在条件状语从句中不能用将来时态表将来，所以错了；D选项中第一空是正确的，但是第二空错误；所以选A。此句话的意思是“被推荐的学生如果通过了北京大学的面试的话， 高考可以加20分”
