问题描述:

1.-Could you tell me at that time?-I was watching TV at home.
A.what you were doing
B.what were you going
C.what are you doing
D.what you are doing

选A首先要用到过去式,你能告诉我在那个时候你在干什么?主句是疑问句所以从句到语序颠倒

A
此处宾语从句需要用陈述句语序,加之根据后面的回答和at that time可知用一般过去时。
希望帮到你!

a.首先可以判断出用过去式,could you tell me (that)...答案既然是从句的一部分,要用陈述语序

B.你能告诉我你当时在做什么吗?
过去进行时态的考察
