it用来充当形式主语或形式宾语,后面的真正主语或真正宾语通常是不定式结构、动名词或名词性分句。It的这种用法叫作先行it。
eg.
It is quite important for us to form a good studying habit.
I think it important to finish the task in time.
it用来充当形式主语,后置的真正主语往往可以取代先行it的位置,出现在句首。
Eg. To form a good studying habit is quite important for us
并非所有先行it结构都可转化,下边句子只能作如下转化。
eg.
It seems that John is not coming after all.
John doesnt seem to be coming after all.
