Question

The problem,____(not,settle),is under discussion.怎么填,
2位啊........英文学的还没我好。= =、这句句子肯定是被动啊...但是NOT BEING SETTLED是错的...T-T

Answer 1

not having been settled
现在分词短语做后置定语,强调动作在主句谓语动词前,即 is 之前
但是最好改为非限制性定语从句,即which is not sttled(或者has not been settled) .因为一般情况下做定语不强调先后关系
做状语时常强调,例如：
Not having received the reply,I wrote a letter again.
