英語專業(yè)四級語法詞匯輔導(dǎo):It的使用
it用來充當(dāng)形式主語或形式賓語，后面的真正主語或真正賓語通常是不定式結(jié)構(gòu)、動名詞或名詞性分句。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用來充當(dāng)形式主語，后置的真正主語往往可以取代先行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 doesnt seem to be coming after all.

Eg. I told him the news yesterday.
Eg. It is I that told him the news yesterday
分裂it
分裂句是以it為引導(dǎo)詞的強調(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。通過這種結(jié)構(gòu)可以強調(diào)除謂語動詞以外的大多數(shù)句子成分。說話人通過分裂句分別強調(diào)主語、間接賓語、直接賓語、狀語，使之成為信息中心。分裂句中的謂語可以采取復(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 Masters Degree.
主語補語通常不作分裂句的中心成分。賓語補語可以這樣用。
It is beautiful that she is.
It is Chairman of the committee that they elected him
