as使用方法 it 不理解

the fashionable criticism of the campaign is revealed as the shallow stuff it often is

看不明白。

The fashionable criticism of the campaign is revealed as the shallow stuff it often is.

本句有两个语言点：

1. reveal...as... 把...揭露为/披露为...，被动式：be revealed as... 被揭露为/披露为。

2.it often is 是定语从句，先行词是stuff，省略了关系代词 that，关系代词在从句中作表语时可以省略。等于：the shallow stuff that it often is.

【等于】对此次竞选活动的时尚批评被揭露为一般是肤浅的东西。
