1题如果用it,得说.It is known to us all that China is a developing country.
2题用的就是我改写第一句的句型
看下面你就明白了:
What is known to us all(主语从句)is that China is a developing country
.It(形式主语)is known to us that China is a developing country(that引导主语从句)
1. 如果用It, it 是形式主语,那么后面就是that 引导的真正主语。而这个句子后面有个系动词is,说明前面只能填一个主语从句,what is known to us all, “我们都知道的是....”
2. 而第二句话就是It(形式主语)+谓语+真正主语(从句)的结构。It,what都能引导名词性从句,怎么用?it 是个代词,不是引导从句的词,it在句子中只能做主语、宾语 wha...

第一题,后面那个is是真真的谓语,所以前边就是名词性短语,因而用What。
第二题,缺少主语,因而填It
