it用來(lái)充當(dāng)形式主語(yǔ)或形式賓語(yǔ)，后面的真正主語(yǔ)或真正賓語(yǔ)通常是不定式結(jié)構(gòu)、動(dòng)名詞或名詞性分句。It的這種用法叫作先行it。
eg.
It is quite important for us to form a good studying habit.
I think it important to finish the task in time.
it用來(lái)充當(dāng)形式主語(yǔ)，后置的真正主語(yǔ)往往可以取代先行it的位置，出現(xiàn)在句首。
Eg. To form a good studying habit is quite important for us
并非所有先行it結(jié)構(gòu)都可轉(zhuǎn)化，下邊句子只能作如下轉(zhuǎn)化。
eg.
It seems that John is not coming after all.
John doesn’t seem to be coming after all.

分裂it
分裂句是以it為引導(dǎo)詞的強(qiáng)調(diào)句型。它的結(jié)構(gòu)形式是：It +be 的一定形式+中心成分+that /who分句。通過(guò)這種結(jié)構(gòu)可以強(qiáng)調(diào)除謂語(yǔ)動(dòng)詞以外的大多數(shù)句子成分。說(shuō)話(huà)人通過(guò)分裂句分別強(qiáng)調(diào)主語(yǔ)、間接賓語(yǔ)、直接賓語(yǔ)、狀語(yǔ)，使之成為信息中心。分裂句中的謂語(yǔ)可以采取復(fù)雜形式
Eg.
It is I who am to blame.
It may have been at Christmas that John gave Mary a handbag.
It was in Shanghai that I got my Master’s Degree.
主語(yǔ)補(bǔ)語(yǔ)通常不作分裂句的中心成分。賓語(yǔ)補(bǔ)語(yǔ)可以這樣用。
It is beautiful that she is.
It is Chairman of the committee that they elected him
