it 作形式宾语

不定式
动名词
that
形式宾语
总结:当复合宾语中的宾语是不定式、动名词宾语从句时, 往往把真正的宾语放在它的补足语后面,而用 it 作形式宾语, 放在宾语补足语之前。
该句型中的 it 作形式宾语, 常用的动词有think, believe, make, find, consider, feel等。
动词+it+宾语补足语+不定式(动名词或从句)
Eg. We think it no use complaining.

It 作形式宾语,常见于“----think / find/ make / believe/ consider+ it + adj / n … + to do sth / doing…/ that 从句”句型中。

He felt it important learning English well.
