It's a relief to know that life enventually gave Charlie Chaplin the stability and happiness it had earlier denied him.
这是什么句式呢~？ 后一个it 是否应为that,这样的话后面就是一个定语从句了。。。。 请各路大侠指点。。。

it 形式主语 真正的主语 to know that life enventually gave Charlie Chaplin the stability and happiness it had earlier denied him.

that life enventually gave Charlie Chaplin the stability and happiness it had earlier denied him. 做know的宾语
后一个 it改为 that that had earlier denied him. 定语从句 修饰the stability and happiness
