【題目】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：你記得當(dāng)車禍發(fā)生時(shí)，你在做什么嗎？what引導(dǎo)的是賓語從句，其語序應(yīng)該是陳述語序，故排除BD；when引導(dǎo)的時(shí)間狀語從句用的是過去時(shí)，問的是當(dāng)事故發(fā)生的時(shí)候，你在什么？當(dāng)主句是一般現(xiàn)在時(shí)，從句的時(shí)態(tài)該用什么時(shí)態(tài)就用什么時(shí)態(tài)，不受主句的影響，故選A。
