此时的it做形式宾语.当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时,通常会在宾语补足语前使用形式宾语it,而将真正的宾语移至句末,其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”:
说几个例子
I find it difficult to do the job well.我发现做好这件事不容易.
I think it best that you should stay here.我认为你最好住这儿.
We think it no use complaining.我们认为抱怨是没有用的.
如第二个句子,认为(think)后边的东西(you should stay here)太长,为了避免头重脚轻干脆放后边,而在think紧后边用个it代替you should stay here.it是形式宾语,you should stay here才是真的宾语.这是英语中的常见用法

应该是个语气词

形式宾语,真正的宾语太长,用it指代

it是形式宾语,代指后面的to do结构,因为真正宾语太复杂,所以用it代替

that is

think it + n. + to do 是一个固定句型
it 是think 的形式宾语,真正的宾语是不定式to do。。。

it形式主语指代to do sth
that 是连接词
