问题补充：

All the work ,and we are going to leave..

A. complete

B. completing

C. have completed

D. has been completed

答案：

A. complete

B. completing

C. have completed

(答案→)D. has been completed

解析：考查时态语态的综合应用。题意为：所有的工作已经完成了，我们正准备好要离开。complete 意为“完成结束”，与“工作”构成被动语意，并且后句中的are 提示应与现在时有关，表示截止到现在已完成。故选D。
