问题补充：
The foreign friends you referred to looking forward to around our university.
A. are ; being shown
B. being ;being shown
C. being ; showing
D. are ;be shown
答案：
(答案→)A. are ; being shown
B. being ;being shown
C. being ; showing
D. are ;be shown
解析：考查句子结构。You referred to是一个定语从句修饰先行词the foreign friends;第一空上应该填are,是句子的真正谓语；look forward to期待，to是介词，后面要加动名词，根据句意，这句话又是被动语态。句意：你提到的那些外国朋友正期待着被带领着参观我们大学。
