　　it 用作形式宾语的用法

　　1)当不定式、动名词、从句等复杂成分用作宾语且后面跟有宾语补足语时，通常会在宾语补足语前使用it 作形式宾语，而将真正的宾语移至句末。其基本结构为“动词+it+宾语补足语+不定式（动名词或从句）”

　　I find it difficult to do the job well.

　　I think it best that you should stay here.

　　We think it no use complaining.

　　2)用作形式宾语的几个特殊结构：

　　①动词+it+that-从句

　　I think it (that) he will come on time.

　　②动词+it+when(if)- 从句

　　We rally appreciate it when she offered to help.

　　③动词+prep.+it+that-从句

　　I can’t answer for it that he will come.我不能保证他会来。

　　④动词+it+介词短语+that-从句

　　I took it for granted that he would help us.

　　(5)it 在强调句中的用法。

　　强调句的基本结构是： It+be+被强调部分+that(who)+其他部分。

　　It was a computer that he bought last week.
