D解析此题考查学生对过去进行时态的掌握。过去进行时态通常表示在过去某阶段或某一时刻正在进行的动作和状态。它表示动作有两个特点：首先是发生在过去，其次是在过去的某一个时刻，具体的某一个时间内。例如：I was talking to my mother when the telephone rang.电话铃响时，我正与妈妈谈话哩。What were you doing on your way home after school yesterday?昨天放学回家路上那段时间你在干什么？I was reading in the reading-room at 4 o'clock that afternoon那天下午四点钟我正在阅览室读书。
