  • it 可以用来指代时间、距离、人物,可以代替不定式、动名词(作形式主语) 也可以用来指代前文提到过的某一事物; eg it is seven o'clock now.(时间) it is 400 miles from A to B(距离) do you really like it(前文提到的事物) who is it?(是谁啊) it takes me 3 hours to finish the work.(形式主语) that用来指代过去的或远处的某一事物,也可用啦指代同类不同物,还可以引导定语从句。 eg the weather in China is much better than that in Japan. which girl do you like better, this one or that one?
