题目内容：

could you tell me_____?I'm not sure.A.when did he come home B.where he would play.
C.if he had seen the movie D.why he didn‘t watch the game 我选C错了 为什么D是对的

优质解答

D
宾语从句要用陈述句语序,而C虽然是陈述句语序,但时态错误,主句是我“现在”问你,他过去发生的一个动作,用一般过去时表达,而用过去完成时的话,要有一个过去的时间作为比对的,可句中并没有这样一个纯粹的过去的时间.
如：could you tell me if he had seen the movie three days ago.
