英语语法求救

Question

_______ is reported in the newspapers , talks between the two countires are making progress.
A, It B, As C , That D, What
疑惑：
1，这句话的主干，从句是什么？
2，麻烦分析下选项解释下各自原因
谢谢

Answer 1

答案：B.

翻译：正如/就像报纸所报道的那样，两国之间的谈判正在取得进展。

解释：
1. 主句主干是talks are making progress.
between the two countries为介宾做后置定语，修饰主句主语talks.
句首是一个以as引导的非限制性定语从句，其中关系代词as代指整个主句talks between the two countires are making progress，在从句（被动句）中充当主语。
2. 其他选项分析：
1）如果选A，则句子必须改成：
It is reported in the newspapers that talks between the two countires are making progress.
其中，it为形式主语，that引导的主语从句做真正主语。
2）that无法用在此题中，也无法改成其他形式。
3）如果选D，则句子必须改成：
What is reported in the newspapers is that talks between the two countires are making progress.
其中，主句主语为主语从句what is reported in the newspapers，且what在主语从句中充当主语；
主句为主系表结构，系动词是is，而表语为that talks between the two countires are making progress这一表语从句。
