Question

Please tell me the problems ________ at yesterday’s meeting quickly. The manager is calling me!

1. A.
   being discussed
2. B.
   to be discussed
3. C.
   discussed
4. D.
   having discussed

Answer 1

C
试题分析：由at yesterday’s meeting可知问题已讨论完毕，故选过去分词短语做后置定语，表被动完成。此处being discussed表示动作正在进行；to be discussed表示将来的动作；discussed   表示过去的动作，有被动含义； having discussed分词的完成时，不能作定语。句意：请马上告诉我在昨天会上讨论的问题。经理正在给我打电话。
考点：考查非谓语动词。
