Question

【题目】By the time they arrived, the enemy forces _______, leaving the small village destroyed.

A.withdrawB.will withdrawC.are withdrawingD.had withdrawn

Answer 1

【答案】D

【解析】

考查动词时态。句意：在他们到达之前，军队已经撤离，离开了被破坏的小村庄。分析句子成分可知，句中By the time they arrived意为“在他们到达之前”为时间状语，是完成时的标志，且arrived为过去某一时间发生的事，因此使用过去完成时形式。故选D项。
