It is said that that was all that he said.这里面的3个that分别做什么成分？

Question

听该啊怎么翻译

Answer 1

第一个that 引导主语从句
第二个 that是从句的主语，是代词
第三个that 引导all 的定语从句

Answer 2

It is said that （先行词，引导后面宾语从句） that （代词，从句中作主语） was all that （引导all后的同位语） he said.

个人意见，仅供参考~

参考翻译为：据说，那就是他所说的全部。

Answer 3

第一个that 引导主语从句：that that was all that he said是主语 is said 是谓语 it是形式主语
在主语从句中that （第二个）是从句主语 was 是系词all 是表语
that he said是all的定语从句。在定语从句中关系代词that在定语从句中作said的宾语
据说那就是他所说的全部。
