I know it that classmates don't know.是一个宾语从句吗?

不是,是同位语从句.
that 引导的同位语从句来解释it那怎样它就成了一个宾语从句了?I know the sentence's mean that my classmates want to know.可以吗原来那个句子把it去掉,i know that classmates XXXXX这个就是that引导的宾语从句了。或者你给的第二个句子里也是宾语从句,不过最好说成I know that the sentences mean that my classmates want to know.这个是双宾语从句,双宾语从句中第一个that不能省略的
