______ is our belief that improvements in health care will lead to a stronger, more prosperous economy.

A．Which                   B．What                      C．It                           D．As

【回答】

C

【解析】

考查it的用法。句意：医疗保健的进步将促进一个更强大、更繁荣的经济，这是我们的信念。that引导的是主语从句，故空格处应该用it作形式主语，代替真正的that引导的主语从句。故选C。

【名师点睛】

It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。
