had not been finished
首先but连接两个并列的句子,but前后的句子都具有完整的结构,都有主谓宾,所以横线上应该填谓语动词而不是非谓语动词.
其次,由but前面的句子是一般过去时,而but后面的句子发生在前面句子之前并将继续发生下去,所以应该用过去完成时,根据句子意思用否定形式.
didn't finish
用had not been finished 吧,当然用was not finished单纯从语法上没有错。
not being finished或者 not having been finished
句子主干:
He offered us a lift when he was leaving the office,but declined his offer,our work not having been finished
