It is 可用于强调句、定语从句、主语从句等多种句型，举例如下：
一、It is(was)⋯⋯that⋯⋯句型, It is + 被强调成分 + that +句子剩余部分 （强调句）
可以分别用来强调主语、宾语、地点状语和时间状语。如：
1、It was he who( that)read three books in the library yesterday.(强调主语)
是他昨天在图书馆读了三本书。
2、It was three books that he read in the library yesterday.(强调宾语)
他昨天在图书馆读了三本书。
It was in the library that he read three books yesterday.(强调地点状语)
他昨天是在图书馆里读了三本书。
二、It is +名词+定语从句
It was the day my grandmother was angry.
那一天我外婆生气了。
三、It is +名词/形容词+不定式主语
It做形式主语，句子真正的主语是不定式。
It was a pleasure to draw pictures.
画画是一种享受。
四、It is + no use + 动名词主语
It做形式主语，句子真正的主语是动名词 。
It is no use doing what you like; you have got to like what you do.
做你喜欢的事是没有用的；你必须喜欢你做的事。
五、It is +名词/形容词+主语从句
It做形式主语，句子真正的主语是主语从句。如：
It was inevitable that the scent of flowers always reminded him of past events.
这是不可避免的：花的味道总是让他想起过去的往事。
六、It 还用于指代时间、距离、价值、天气，以及不明确的人（包括性别不明的婴儿、敲门或打来电话的人。在不知道对方性别前，无法确定该用he还是she，往往用it）。
It was a bright cold day in March.
这是三月的寒冷的一天。
it is,大多数地方可以通用.貌似只有一个例外,就是放在句尾的时候
例子：Is it an apple?那是一个苹果么?
yes,it is.这时候不能说 yes it's
就是说it's不能用作句子结束语,后面必须跟上宾语
its的区别就大了
我给你列个表格,看能看懂不能：
I me I am my mine
you you you are your yours
he him he is his his
it it it is/it's its
最后那个问号,是我自己也不清楚,its是否能做名词性的
总是,its和其他两个的意思都是不一样的,是所有格形式.
关于its的例子：
the bird is licking its wing
那只鸟在舔它的翅膀
