Last year he paid a visit to his hometown, which was no longer the sleepy little village______.A. it wasB. it has beenC. it had beenD. it was being

步骤 1：理解句子结构
句子的主干是 "Last year he paid a visit to his hometown"，其中 "which was no longer the sleepy little village______" 是一个非限制性定语从句，用来描述 "his hometown"。

步骤 2：分析定语从句
定语从句中 "which" 指代 "his hometown"，"was no longer" 表示 "不再是"，"the sleepy little village" 是定语从句的宾语，"______" 需要填入一个表示过去时态的从句，来描述 "the sleepy little village" 的状态。

步骤 3：选择合适的时态
由于 "Last year" 表示过去的时间，而 "the sleepy little village" 是 "his hometown" 在 "Last year" 之前的状态，因此需要使用过去完成时态，即 "it had been"。
