一、用作人称代词
1.用于指事物
it用作人称代词最基本的用法就是代替前面已提到过的事物，以避免重复，it可用作句子的主语或宾语。

这是我的手表，它是瑞士制的。

5.指人时与he和she的区别
当it用于指人时，主要用于确定未知的或者是身份不明的人，若是指已知的或身份明确的人，则应根据情况使用he或she。

6.指物时与one的区别
两者均可代替前面提到的事物，区别是：it指的是与前面已提到的事物为同一物，此时的it等于“the （this， that， my ...）＋名词”；而one 指的是与前面已提到的事物为同一类物，此时的one等于“a＋名词”。

三、用作形式主语
it用作形式主语，所代替的是句子的逻辑主语，并无实际词义。这样可以保持句子的结构平衡，避免主语太长，显得头重脚轻。当从句、动词不定式或动词-ing形式作主语时，可以用it作形式主语。
1.代替从句作形式主语
it常用于以下句式：
（1）It＋be＋形容词＋从句

这项工作必须做好。
（2）It＋be＋名词＋从句

It is no use giving him some advice.
给他提建议没有用。
（2）It is＋形容词＋doing sth
It’s pleasant sitting here.
坐在这里很愉快。

四、用作形式宾语
当动词不定式、动词-ing形式（短语）或从句在句子中作宾语时，为了保持句子的结构平衡，常用it作形式宾语，而将真正的宾语放在句子后面。it作形式宾语的常用句式有：
1.主语＋find/think/feel/make/consider/believe＋it＋名词/形容词＋（for/of sb） to do/that ...；其中for或of引出动词不定式的逻辑主语。
I don’t feel it difficult to understand English.
我觉得理解英语并不难。
They found it pleasant that they worked with us Chinese.
他们发现与我们中国人一起工作很愉快。
2.主语＋find/think/feel/consider/believe＋it＋no use/no good＋doing sth。
Do you think it any good trying again？
你觉得再试一次有用吗？
