题目

4.The plans ▁▁▁by many managers now will be carried out next month.
A.being discussed B.discussed C.to be discussed D.having been discussed

答案

答案是B
首先这个地方不是现在进行时! now是干扰成分.
这个地方应该是plan的定语
the plans （which have been discussed by many managers)
一般现在完成时 被动语态 不可以采用任何其他的时态.
所以排除了A 和D
更不可是动词不定式 排除C
所以选B whic have been 被省略.
