Question

We were told that Mr Green _____ the office for a few minutes when we arrived.

A．has been away from

B．had left

C．had been away from

D．has left

Answer 1

C

试题分析：句意：有人告诉我们，当我们到达办公室的时候格林先生已经离开好几分钟了。由于句子当中含有表示一段时间的状语for a few minutes，故谓语动词必须用延续性动词；leave离开，是一个非延续性动词，当与一段时间连用时，必须换成be away from。根据when we arrived可知主句必须是过去时态，所以选C。
