问题描述:

as is reported in the newspaper与it is reported in the newspaper的区别
_____is reported in the newspaper,talks between the two countries are making progress.
A.It B.As C.That D.What
怎么选,为什么?

选B,前面分句充当的是状语从句可是答案是A诶,而且网上as和it都有,我以前一直觉的it的话,要it is reported in the newspaper that……的,那是答案错了?还是怎么回事?反正我觉得是B,除非还有上下文,A觉得有点别扭
