I have no idea where he comes from是同位语从句? "I have no idea where he comes from."是同位语从句吗?如果是,为什么连接副词wher 为啥I have no idea when he will be back是同位语从句 i have no idea后到底接的是同位语从句还是宾语从句 They have no idea at all where she has gone .这句话是同位语从句还是宾语从句 I have no idea what has happened to him为什么是同位语从句 l have no idea when he will be back这为什么是同位语从句?我觉得是定语从句. 请问这是定语还是同位语从句啊?have no idea which class he is in which 可以引导同位语从句吗?I have no idea which one I should choose?是什 i have na idea when he will be back.这是定语从句还是同位语从句 高中英语同位语练习They have no idea at all _____A where he has gone B 同位语从句只用that作为开头（I have no idea除外） 为何
