问题描述：
“It is known that Chinese people are smart.” 中的It 指代什么?
假如作文的第一句话就是It is known that Chinese people are smart.这样写对吗?It 没有指代对象啊,只能理解为the fact,可是这句话里并没有.
答
“It is known that Chinese people are smart.” 中的It 指代that Chinese people are smart.it 不是只能指代一个名词吗？SAT作文中让这么用吗？it 不只是指代一个名词。it可以指代天气、距离和时间；it可以做形式主语；it可以做形式宾语。
“It is known that Chinese people are smart.” 中的It作形式主语， 指代that Chinese people are smart这个真正的主语。
