  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.
