Where she put it is unknown to us all
最前面加个That,为什么句子就错了?我知道不加是对的,主语从句嘛我知道的.我就是想知道加That为什么错了,主意我问的是什么啊,

疑问词可以引导主语从句,that 也可以引导主语从句,但是两者不能同时使用.我再举一个例子：宾语从句可以用 that 引导,但是 I don't know that where he lives.就错了,道理是一样的.
再问：有道理，我感觉也不对劲啊，就是在道理上弄不懂，他们都说什么连词不能重复，说的是什么意思啊？
再答：连词不能重复，说的是一个从句只需要一个连词就够了。没有必要同时使用两个连词。
再问：那这里的that和where都是连词吗？怎么一会连词一会引导词把我弄晕了
再答：严格来说，连接从句的词应该称为“引导词”或“主从连词”，但是很多人为了方便，把它叫做连词，这是不严密的说法，但是大家都理解。
