请问这句话 里主语从句为什么省略了that

Question

it is said in Australia there is more land than the goverment knows what to do with it .

Answer 1

这个句子的语法结构如下：

形式主语：it 【指代后面的从句，即后面提到的这件事】

谓语动词：is said 【被动语态，直译是“被（人们）说了】

主语从句：(that) in Australia there ismore land than the government knows what to do with it 【主语从句出现在句首 that 不能省略，拖后到句尾时在非正式英语中常被省略】

It is said that …意思是“据说…”，用正常语序表示则为“that… is said”，改为主动语态是 somepeople say that …。因此，这个句子就有以下三种写法：

主动语态：Some people say (that) inAustralia there is more land than the government knows what to do with it .【that 引导宾语从句】

正常语序：That in Australia there is moreland than the government knows what to do with it is said.

倒装语序：It is said (that) in Australiathere is more land than the government knows what to do with it

之所以用被动语态是因为说话人想强调事实本身，而不重视这件事是什么人说，而用形式主语 “垂帘听政” 则是为了避免头重脚轻的句式结构。类似的用法很多，如：

It is reported that … （据报道…）

It is recorded that … （据记载…）

It is rumored that … （据谣传…）

It is known that … （据悉…）

Answer 2

it is said THAT in Australia there is more land than the goverment knows what to do with it .
----------道理很简单，因为这是口语化的句子了。对有英语基础的人来说，that的省略是很常见的。

语法结构：
it （形式主语）is said（谓语） THAT（主语从句的连接词） in Australia there is more land than - - - （真正主语）

Answer 3

不是主语从句。
宾语从句。追问

（it 主语）（is said 谓语）（ in Australia地点状语）（ there is more land than the goverment knows what to do with it宾语从句） .

为什么it 不是形式主语 后面是真正的主语呢 怎么判断
