I didn't know where he lived还是I didn't know where he lives对?

问题描述:

I didn't know where he lived还是I didn't know where he lives对?
-Why didn't you go to his birthday party yesterday?
-Because I didn't know ______.He forgot to tell me.
A.where did he liveB.where he livedC.where does he liveD.where he lives
选B还是D啊,我认为选B的话,是说我那时候不知道,但是现在知道了;选D说明我一直不知道,现在也不知道.

选D.I did not know where he lives.
因为where he lives 是现状,不是过去.
I did not know 后面可以接现在时.例如:Ancient people did not know that earth is round.古代人不知道地球是圆的.
