it is the fact that是同位语从句么?另外fact,news,等后也可能是定语从句吧?怎么判断

it is the fact that ... 可以是主语从句
eg。 It is the fact that he lost all his money.= He lost all his money is the fact.
it is the fact that ... 还可以是强调句
eg. It is the fact that is he lost all his monry.= The fact is that he lost all his money.
fact, news 后可以接定语从句（判断方法看一楼）
eg The news that he received yesterday is unbelievable.
