Jack offered us a big meal when he was leaving the office, but our work ____, we refused it. A．not finished B．had not been finished C．not having finished D．wasn’t finished

Answer 1

A

考查独立主格结构。our work not being 叫做 独立主格结构，这里做状语，表示原因，相当于 because our work was not finishedA, C 用的是主动式，显然不对。B 似乎对，但是两个并列句中间不能这么用逗号隔开。如果在we 前面加一个so就对了。故选A。
