Question

it was said that was all that that girl had said.详细介绍下此句型

Answer 1

据说那就是那个女孩所说的一切。
首先主句是it was said,后面跟了一个省略了that宾语从句，即在said和that之间还有一个that.在宾语从句中，主语是that，was是系动词，然后宾语从句中又套了一个表语从句（all that that girl had said),all that就等于what,这里的第二个that是指示代词，意思是“那个”。

所以，it was said翻译为“据说”，that was翻译为“那就是”，all that that girl had said翻译为“那个女孩所说的一切”

Answer 2

it was said that ~~~据说

Answer 3

定语从句
主语：that girl
听说所有的事情都是那个女孩已经说过的。

Answer 4

It was said (that)...据说,接宾语从句
that was all that...宾语从句再接宾语从句
that girl had said这个that 是那个的意思
整句话的意思是：
It was said / that was all (that) / that girl had said
据说 整件事就是 那个女孩所说的。

Answer 5

据说那是那个女孩说过的所有的话
有两个从句said...后是宾语从句
all..后是定语从句
第一个that是主语代词，在宾语从句 that was all...中作主语
第二个that是第二个定语从句引导词，引导修饰all
第三个that作形容词，修饰girl，意为那个
