We all found ( it ) very interesting to eat.为什么要用it?

问题描述:

We all found ( it ) very interesting to eat.为什么要用it?

it是形式宾语,而to do是真正的宾语。very interesting做it的补语。

形式宾语it指代to eat

你只要记住这个句型就可以了:find / think it + adj.to do sth
it是形式宾语.
very interesting是宾补,而to do是真正的宾语.
其实括号里也可以填"it was",也就是把它当作宾语从句来写,
但是要注意从句和主句时态一致.
