1. it也可以代替不定式或从句在句中作形式主语,即:
It be +adj. +(n.)+that +clause或It be adj. +to do sth.,那么that引导的从句和不定式是句子中的真正主语,这个用法是为了避免长句作主语导致句子的不对称,如:
It is difficult to finish this job on time(= To finish the job on time is difficult).要按时完成这项工作是很困难的。
It is strange that she doesn’t want to travel. 她竟然不想旅游,这个让人感觉很奇怪。
It is a good thing that he helps me with English study on Sunday. 星期天他帮助我学习英语是一件好事。
2. it作主语时可以指时间,日期,距离或天气,也可以指无识性别的婴儿。如:
It’s ten past twelve. 现在是十二点十分。
It is two miles to the beech. 离海滨有两英里。
It was raining this morning. 今天早上天在下雨。
It is Saturday today. 今天星期六。
