问题描述:

She finds ____difficult to predict what will happen in the future
A. it B that C .This D.its 加上原因!

选A. it是充当形式宾语的,而语法规定其它的代词不可以这样用。

A
固定句型find it +adj. to do sth 发现做某事怎么样, IT 作形式宾语,真正的宾语是后面的动词不定式短语

A find it difficult to do sth

A
只有it是形式主语,it指代to predict what will happen in the future

A
主语:she;
谓语:find;
形式宾语:it;
宾语补足语:difficult;
真正的宾语:不定式to predict ……
另外,
She finds (that) it is difficult to predict……也对,(it后面得有is)
