The plan to be carried out next month needs _______ among the members of the labor union before _________ .
A．to discuss, carrying out
B．to be carried out, carried out
C．discussing, being carried out
D．discussed, to be carried out
答案
答案：C
考查固定短语和动名词用法。Sth Need doing="sth" need to be done需要做某事；before是介词，后面接动名词，根据句意可知计划和执行存在被动关系，所以使用过去分词表示被动。
