问题补充：

The bridge , after it is completed, will surely shorten the distance between the two cities.

A. building

B. built

C. being built

D. having built

答案：

A. building

B. built

(答案→)C. being built

D. having built

解析：考察非谓语动词。本题中的动词build与句子主语the bridge构成被动关系，根据第二句中的will可知前句表示的是正在进行的事情，故使用现在分词的被动形式作为定语修饰名词。本句考生一定要注意句子的结构。句意：那一座正在被建设的桥梁在建成以后一定会缩短两个城市之间的距离。故C正确。
