大牛帮忙看看这道语法题

凌雨萱

Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.
答案是：superficial, as when the three major networks each  请问as when 这是什么结构，as引导什么？

酱子啊

AS不是引导When,也不是有AS WHEN 结构。
它是引导when the three major networks 这个。。。
你体会下。这里的主结构是as，，跟when 没什么关系
还有如果只是有when，它是绝对错的。when不能用来引导条件从句
这个我个人理解，欢迎打叉。。
