Question

---- Look! Everything here is under construction.
---- Oh, has the building once ___ for exhibition been pulled down, too?

A．having been built

B．being built

C．to be built

D．built

Answer 1

D

这题考查过去分词做定语的用法：the building和build是被动关系，因为是已经建成了，所以用过去分词做定语。选D。句意是：--看这儿的一切都在建设。--为展览建的大楼也被推倒了吗？选D。
