下面就其使用的重点及难点,分门别类地加以总结。
1. 作人称代词,可以用来代替人、物或事；亦作非人称代词，表示时间、天气、季节、距离等。
It i s r aining c ats a nd d ogs. 雨下得很大。
It is a long way to the college. 大学距这儿很远。

The baby cried because it was hungry。
小宝贝因为饿而哭了。
3. 作形式主语英语中不定式、动名词、主语从句在作主语时，主语往往显得很长，使整个句子看上去有点头重脚轻，这时就需要借助“It”作形式上的主语，而把整个句子的主语移到句子后边去，使句子看上去平稳一些。
It is difficult to study and work at the same time.一边工作一边学习很难。
It is very clear that the elephant's l eg is round a nd tall like a tree.大象的腿跟树干一样圆而高，这点显而易见。

用it指代下句中的the air, the weather, the way of life ，其他代词不合适。
考点二、引导词it 的用法1．作形式主语，当动词不定式、动名词或从句作主语时，通常把它们放在谓语之后，而用it 作句子的形式主语。
例如：It took me 3 hours to get home last night. 昨晚我花了三个小时才到家。
（不定式作主语）It’s no use trying to explain－I’m not interested. 解释没有用－我不感兴趣。
（动名词作主语）It appears that Geoffery might change his mind. 杰斐里可能改变主意。
（that 从句作主语）It wasn’t very clear what she meant. 她是什么意思不是很清楚。
(what引导的从句作主语) 【高考链接】_______ is our belief that improvements in health care will lead to a stronger,more prosperous economy.A. AsB. ThatC. ThisD. It解析：这里it 作形式主语，真正的主语是that 引导的从句improvements in health care will lead to a stronger, more prosperous economy。
2. it 用作形式宾语。
不定式、动名词短语或名词性从句作宾语时，如果后面带有宾语补足语，常用it作形式宾语，而把真正的宾语放在宾语补足语后面。
例如：He found it very difficult to stop smoking.The professor thinks it no good reading without understanding.【高考链接】He didn’t make ____clear when and where the meeting would be held.A .this B. that C it D. these【高考链接】As the busiest woman in Norton, she made _____ her duty to look after all the other people’s affairs in that town.A. thisB. thatC. oneD. it解析：答案为D。
本题考查了代词it做形式宾语而不定式短语做真实宾语的用法，这是中学英语的主干知识。
考点三、it 用作强调时的用法用于强调结构，要强调句子的某一部分（通常是主语、状语、宾语）可以把it 当作先行词，这种句子的结构是：“It is (was) + 被强调的部分+ that(who )+ 句子其余部分”。
如果强调的主语部分是人，可用who代替that。
在这种结构中，it 不可用this或that替代。
例如：It was I who / that meet an old friend of my father’s in the street yesterday. (强调主语)It was an old friend of my father’s that I met in the street yesterday. (强调宾语)It was yesterday that I met an old friend of my father’s in the street. (强调时间状语，注意不可用when 代替that)It was in the street that I met an old friend of my father’s yesterday. （强调地点状语，注意不可用where 代替）注意：下面两个句子第一个句子是时间状语从句，要用when；第二个句子是强调句式，要用that。
It was Dec. 18th when she was born. 她出生那天是12月18日。
It was on Dec.18th that she was born. 她是12月18日出生的。
【高考链接1】It was after he got what he had desired ______ he realized it was not so important.A. thatB. whenC. sinceD. as解析：答案为A。
此句为强调句型。
被强调部分after he got what he had desired为句子的时间状语从句，且其中还包含着一个宾语从句what he had desired。
【高考链接2】－______that he managed to get the information ?－Oh, a friend of his helped him.A. Where was itB. What was itC. How was itD. Why was it解析：答案为C。
