问题补充：

A. finished
B. to be finished
C. having finished
D. was finished
答案：
(答案→)A. finished
B. to be finished
C. having finished
D. was finished
解析：句意:约翰当他的工作做完时，他收到了晚宴的邀请函，所以他高兴的接受了邀请。With+宾语（名词/代词）+宾语补足语（to do/doing/done/adj./adv. ）with的宾语复合结构。此空宾语work与宾语补足语之间是被动关系，又根据谓语 received，表示过去，因此用过去分词finished。故选 A。
