由于“it”既可以指人,也可以指物,还可以指代很多内容,因此将它称为万能代词。
A. 用来指代不明身份的人。比如:
Is it a boy or a girl
There is a knock on the door. It must be the postman.
B. 指代一个物体或时间、距离、天气、气候、温度、自然现象等。比如:
I dropped my watch and it broke.
--“Where is the dog ” --“It’s in the bedroom.”
It’s 8 o’clock in the morning.

万能代词“it”:
C. 指代一件事或上文提到过的某项内容等。比如:

Nothing is wrong, is it
It’s hard work, but I enjoy it.
我们都认为这事一定不对。
没出什么问题,是吗

D. 指代一个句子说明的事情内容。比如:

如果你一直做那事,会对你的身体产生危害。
E. 用在强调句中,没有具体意思,也不能用“this”替代。比如:

▲ “it”的用法是必考的重点之一。
这是史密斯先生第一次来中国访问.
充当形式主语:
A. 指代动词不定式说明的动作内容等。比如:

It took me two hours to finish the letter.
It’s too late to go there now.
去记住这一点是很重要的。
写这封信花了我二个小时。
现在去那儿(这件事),已经太迟了。
“It is important for sb. to do sth.”结构是不是句型?
比如:It is important for us to leave now.
正常表述:To leave now is important for us.
B2句型
类似的句式还有:
It’s a good idea to plan ahead.
It’s a funny sensation to know someone's talking about you in a language you don’t understand.
It doesn’t matter (for you) to break the rules here in our company.
动词不定式做主语时,常借”it”来作形式主语,而将真正的主语放到句后。
结论:所以这也是个特殊的句式,不是基本句型。

It’s hard work climbing mountains.

It encourages us (that) she is still alive.
It is still unknown whether she is still alive or not.
It has been decided whether/if he will go there.
It has not been told yet whether/if he has gone there.
It is very clear now whose key this is.
It can make you better whoever you meet.

充当形式宾语:
A. 在句子中充当宾语时,用以指代不定式或从句所指事情内容。比如:

充当形式宾语:
B. V4句型中的宾语从句。比如:

They discovered what they had learned (to be) valuable.
这种情况下,常用“it”来指代宾语从句,而将宾从放到后面:
I think it necessary that we take plenty of hot water every day.
He feels it a pity that his son hasn’t got the first prize.
I have made it a rule that I keep diaries.
