为什么有there is possibility that这样的同位语从句,没有there is a fact that

为什么有there is possibility that这样的同位语从句,没有there is a fact that There is no denying the fact that+同位语从句 能否把that前的用语法解释一下?总感觉 请用这组词造个句子where there is a fact that …………there is possibility it还是there is a possibility that There is no doubt that he is guilty.为什么是同位语从句 it is a fact that 这个句型到底是同位语从句还是主语从句? there is a possibility that it will rain.中为什么用that而不用which 和 case情况 后不能加that 引导同位语从句吗？例：There is a case that it is a possibility that 可不可以这样说 为什么 为什么有 There is no possibility ,而没有 It is no possibility it is...that..与there be..that..引导的从句有没有共同点 the fact is that和the fact that一样吗?前面是表语从句后面是同位语从句吗?
