问题描述:

一道高中语法题(要解析,
___has been announced ,we shall have our final exams next month.
A.As
B.What

选A,这种题就像数学套公式。这种题一般有三种模式:1:It......that......,what......is that......,[as......,......]

A
what后面没逗号 是一句话

选A 翻译过来是正如被宣布的,我们将在下个月举行期末考试
B不能选,what形成主语,后面的we也是主语,句子矛盾

A 这里as引导的定语从句修饰后面整个句子 用法类似which 但因为是在句首 故必须用as
