选A
at that time 指之前的一个时间,表示过去时态,陈述语句

选A 第一步，排除BC，又因为用陈述句语序，故选A

选A 这是一个宾语从句 而且是过去进行式

这个我来讲讲

这道题选a,因为由at that time可知为过去式，又因为为陈述句语式，所以选a

A。。。。

选A，“你能告诉我他们在那个时候在做什么”。 what引导宾语从句时，语序要还原，所以去掉C和D。另外是问那个时候，应该指过去，所以排除B

哎呀djvdjskbdjbjiubhdsvbkb

D 我感觉at that time 为过去 那个时间里 他在做什么的一个问话 应该用过去进行时 来问

选A，首先根据句尾的at that time知道这句话是过去进行时，所以BC排除，又因为这种句式要用陈述句语序，所以were要放在they后面，故选A

选A，望采纳。错了可以申诉我
