解题思路： 分析结构
解题过程：
is reported in the newspaper ,talks between the two countries are making progress.
A.It
B.As
C.That
D.What
选B，as引导非限制性定语从句，在从句中做主语，代指整个主句的内容
如果用it的话，it做形式主语，真正的主语是后面的从句It is reported in the newspaper that talks between the two countries are making progress.
what可以引导主语从句，要这样what is reported in the newspaper is that talks between the two countries are making progress.（that引导表语从句）
