Question

【题目】Do you remember ________ when the car accident happened?

A. what you were doing B. what were you doing

C. what you did D. what did you do

Answer 1

【答案】A

【解析】句意：你记得当车祸发生时，你在做什么吗？what引导的是宾语从句，其语序应该是陈述语序，故排除BD；when引导的时间状语从句用的是过去时，问的是当事故发生的时候，你在什么？当主句是一般现在时，从句的时态该用什么时态就用什么时态，不受主句的影响，故选A。
