It has been said that when people succeed,这是什么句式?帮忙划分下各个成分It has been said that when people succeed,it is because of hard work and that luckhas nothing to do with success.帮忙分析下句子吧

楼主你好：
1. It has been said 固定搭配，后接that从句，意思是据说。
2. that when people succeed, it is because of hard work是跟着的第一个that从句。
（其中when people succeed：时间状语， it is because of hard work: 从句的主语。）
3. that luck has nothing to do with success是跟着的第二个that从句。
4. 句子译文：据说，人们能成功是努力工作的结果；和运气并没有关系。

It 形式主语
has been said 谓语
that when people succeed, it is because of hard work：真正的主语（主语从句）
在从句中，when people succeed, 时间状语
it is because of hard work: 从句的主语
that luck has nothing to do with success: 另外一个主语（主语从句）
句子译文：人们曾说过，人们成功是努力工作的结果；运气和成功并没有关系。

It has been said that（看到这个that 明显就是形式主语,主要表的意思在that后面） when people succeed（when开头这部分是状语,表示一种条件） ,it is because of hard work and that luck has nothing to do wit...
