Question

【题目】Most of the guests ________ for almost an hour when David arrived at the party.

A.had been awayB.had leftC.left

Answer 1

【答案】A

【解析】

句意：大卫到达聚会时，大多数客人都离开了将近一个小时。

had been away过去完成时，动词是延续性状态；had left过去完成时，动词是非延续性动词；left过去式。根据句意可知“离开”动作发生在过去的过去，所以用过去完成时，和一段时间连用，动作用延续性动词或者表示延续性状态的词，故选A。
