问题补充：

around the Water Cube, we were then taken to see the Bird’s Nest for the Olympic Games.

A. Having shown

B. To be shown

C. Having been shown

D. To show

答案：

A. Having shown

B. To be shown

(答案→)C. Having been shown

D. To show

解析：考查分词做状语。Show around与we构成被动关系，故使用过去分词表示被动，排除AD。根据句意说明被带领参观水立方是先发生，故使用完成式。排除B。句意：被带领着参观水立方以后。我们又被带领着参观了奥运会的体育馆鸟巢。故C正确。
