d they have a good journey home?do you knew?合并为一句
问题描述：
d they have a good journey home?do you knew?合并为一句
you know if they have a good journey home,那块不应该是had吗
did they have a good journey home
答
Do you know whether / if they have a good journey home. 主句中为一般现在时,从句中该用什么时态就用什么时态.但是那句是过去时啊，变回陈述have不就是had了Do you know whether / if they had a good journey home.答案有误。你的说法是对的。
