(3)指代上文提到的事物

(4)作形式主语或形式宾语，代替动名词、不定式或从句
1.It is unknwn when he will cme.他什么时候来还不知道。(it作形式主语，从句是真正的主语)
2.I find it difficult t wrk with him.我发现和他一起工作很困难。(it作形式宾语，不定式是真正的主语)
注意:某些动词(短语)后接从句时要用it作形式宾语，再接从句，构成“动词(短语)+it+that/if/when/...从句”，如：①I hate/like it when... 我讨厌/喜欢...②Yu shuld see t it that... 你应该确保...③Yu can depend n it that... 你可以相信...④I can’t help it if... 如果...我也没有办法⑤I wuld appreciate it if... 如果...我将感激不尽

(6)高考实战分析&练习-it
高考主要考察it作替代词；it与ne,that的区别,it作形式主语、形式宾语的用法，以及it用于固定句式、强调句型的情况。
答题时，无法判断填什么词时，要考虑句子是否为含有it的固定搭配或句式。
实例:(浙江卷)Many westerners wh/that cme t China ck much less than in their wn cuntries nce they realize hw cheap ____ can be t eat ut.
分步解答:①分析句子成分:“hw cheap ____ can be t eat ut”是宾语从句，且为感叹句结构，空格处在句中作主语，但句中的不定式t eat ut是主语，所以空格处需要用形式主语;②确定代词形式: it可作形式主语。
实例:(全国卷Ⅱ·改编)Sarah made ____ t the airprt just in time t catch her plane this mrning.
分步解答:①分析句子成分，made后面缺少宾语;②分析句意: “今天早上萨拉及时到达了机场，正好赶上飞机。” make it 为固定搭配，意为“成功做某事;及时到达”
实例:(全国卷Ⅰ)If yu are time pr,yu need run fr nly half the time t get the same benefits as ther sprts,s perhaps we shuld all give ____ a try.
实例:(四川卷·改编)New technlgies have made ____ pssible t turn ut new prducts faster and at a lwer cst.
实例:(全国卷Ⅰ)If yu are time pr,yu need run fr nly half the time t get the same benefits as ther sprts,s perhaps we shuld all give _it__ a try.
give it a try/g试一试固定搭配
实例:(四川卷·改编)New technlgies have made _ it__pssible t turn ut new prducts faster and at a lwer cst.
①have made后缺少宾语②不定式引导的句子为真正主语③使用it作形式宾语
