The Town Hall ______ in the 1800's was the most distinguished building at that time.

A.to be completed

B.having been completed

C.completed

D.being completed

答案及解析： C

解析：

思路

分析：The Town Hall与completed是被动关系，故用过去分词作定语修饰The Town Hall。having been completed表示动词已开始到现在仍在进行，与句意不符；

to be completed表将来完成；

being completed表正在进行，都与句意不符。【点评】考查非谓语动词的时态，难度较大。
