题目

_______ is announced in the papers,our country has launched a large-scale move说明原因
_______ is announced in the papers,our country has launched a largescale movement against smuggling and fraudulent activities in foreign currency exchange deals.
A.What B.As C.Which D.That

答案

正确答案是B,
解法一：排除法：
A：what ,是不正确的,因为what 引导的从句是做主语或是宾语的,而这道题目中,根本没有这样的迹象,所以A错
C：Which,也是不对了,Which引导的宾语从句,是来修饰宾语的,比如You get the book which I really want .（这本是我很想要的书）
D：That,一般和Which 的用法是差不多的,但是That的用法还是比which多一点.
解法二：直接选择
As is announced in the paper ：正如纸上宣布的那样.
这样的结构和 as you can see [正如你看到的那样] 有些类似
