题目内容
－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.
－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 |
B
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.
