Question

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

考查獨(dú)立主格結(jié)構(gòu)。our work not being 叫做 獨(dú)立主格結(jié)構(gòu)，這里做狀語(yǔ)，表示原因，相當(dāng)于 because our work was not finishedA, C 用的是主動(dòng)式，顯然不對(duì)。B 似乎對(duì)，但是兩個(gè)并列句中間不能這么用逗號(hào)隔開(kāi)。如果在we 前面加一個(gè)so就對(duì)了。故選A。
