A.This is B. There is C. That is D. It is 为什么选D?

题目

A.This is B. There is C. That is D. It is 为什么选D?
D. it is one's hope that .it是形式主语 ,为何不能看做同位语从句选A.This is.
The Foreign Ministry said,"__our hope that the two sides will work towards peace."

答案

这个题目不是强调句型,强调句型的判断方式是把it is..that这三个词去掉句子仍然正确,这个句子去掉是不正确的,这里it是形式主语,真正的主语是后面的that从句（双方朝和平方向发展是我们的愿望）,this不可以作形式主语
