Question

－My parents         our home for a few hours when I arrived. I didn’t meet them.

－You could call them if you wanted to know where they were.

A. have been away from  B. had been away from   

C. had left     D. had gone

Answer

B

【解析】

试题分析：句意：---当我到家的时候，我的父母已离开家几个小时了。我没遇到他们。---假如你想知道他们在哪里的话，你可以给他们打电话。当我到家的时候是过去时间状语，所以我的父母已离开家几个小时了。for a few hours表示一段时间，不能与非延续动词连用。所以要用过去完成时态。故选B.

考点：考查完成时态的用法。
