一、人称代词

⑵.指时间: It was nearly midnight when she came back.
⑶.指日期:It is April First today.
⑷.指距离:It is some 3000 kilometers from Beijing to Guangzhou.
⑸.指价值:It is three dollars.
①It is suggested that the meeting ( should ) be put off.
②It was ordered that we ( should ) arrive there in two hours.
⑸It is time ( about time，high time ) that从句(虚拟语气:动词用过去时did)
1It is time that children went to bed.
2It is time you bought a new car.
3It is (high ) time you made up your mind.
⑹It is the first ( second ... ) time that从句(从句用现在完成时have done )
3.，也可指抽象事物或指抽象环境和情景:
③I hate it when people talk with a full mouth.．
二、.非人称代词
1.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等：
⑴.指天气：It is a lovely day, isn’t it?
⑹.指温度:Today it is 30 degrees centigrade.
3、其他用法
1.在句子的主语不太明确时充当主语，表示谁在做某事：
①Who is it there? It's I (me/you/he.....).
②I thought it was Mary, but it was not she.
⑺It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that从句.
that后的从句一般用虚拟语气（should +动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。
①It is important that we (should) learn English well.
②It is necessary that he (should) remember these words.
⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that从句常译为＂据说（据报道，据悉．．．）＂。
3.it用在一些词组中，it没有特别的意思
The last train's gone.Come on, we'll foot it.(来，咱们步行吧。)
四、作形式主语，替代主语从句，动词不定式，或动名词短语：
1.作Βιβλιοθήκη Baidu式主语替代主语从句
⑴It is clear ( obvious，true，possible，certain....) that从句常译为＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂
= That he’s round and tall like a tree is very clear.
