Question

【题目】Did you ask the teacher the day before?

A.what was happened to herB.what she had happened

C.what she happenedD.what had happened to her

Answer 1

【答案】D

【解析】

句意：你问老师前一天她发生了什么事吗？

这里是宾语从句，注意用陈述语序，happen表示发生，无被动语态，短语happen to sb.表示某人发生了什么事；根据主语是一般过去时态及时间状语the day before可知从句用过去完成时，其结构是had done的形式。根据题意，故选D。
