Question

—The hall      for international conferences is of great importance.
—I see, and we are sure to complete it on time.

A．built

B．to be built

C．having been built

D．building

Answer 1

B

试题分析：句子主干为：The hall is of great importance。be of great importance ＝ be very important，主语the hall 后为非谓语动词短语作后置定语。因the hall 与动词build 之间为被动关系，首先排除 B，从答句中的．..we are sure to complete it on time 可知该大厅还没有完工，因此排除表示“被动完成”的A、C 两项，而选表示“未来将完成”的不定式的被动式。考点:考查不定式的被动做定语
点评;非谓语作定语含义不一样：done做定语，表示被动和完成； being done做定语，表示被动和进行； to be done做定语，表示被动和将来。
