I have no idea (that) when he will come back home那个位置可以有that么?是不是因为后面有特殊疑问词

又有句话I have no idea that you were there其中that不可省略,那为什么上面那句话就没有that呢??谢谢

1不能有that
不是 是同位语从句

第二句的
that是引导同位语从句

I have no idea (that) when he will come back home
wh词引导同位语从句
不是省却that而是不能有that
I have no idea that you were there
正常的同位语从句,所以that引导

却别在于第一句有when,具体怎么解说我也不知道。

I have no idea (that) when he will come back home
这里不再用that了。
后面不是特殊疑问句,是一个从句,做同位语修饰idea

I have no idea that you were there的that不能省略,因为that在句中引导同位语从句。
