Question

【题目】By the time I________up, my mother________to do volunteer work in our community.

A.woke; had goneB.wake; has goneC.woke; has goneD.wake; had gone

Answer 1

【答案】A

【解析】

句意：当我醒来的时候，我妈妈已经去我们社区做义工了。

考查动词的时态。by the time 到……时，后跟一般过去时，因此第一个空填woke，排除B/D；第二空，“我妈妈去我们社区做义工。”发生在我“醒来”之前，因此用过去完成时，即：过去的过去。其结构是：助动词had+动词的过去分词。故选A。
