as so often is the case - 柯帕斯英语网

As so often is the case,stating that principle doesn't ease the challenge of line-drawing.

一般常见的用法是“as is often the case“。传统语法认为as 是关系代词，引导非限制性定语从句，as 指代整个主句，在从句中作主语。那在”As so often is the case”中so often为什么能提前呢，这是一种倒装吗？

你的分析是对的，as是主语。often为中位副词，通常位于操作词之后。但如果强调句子的肯定性，操作词重读，则中位状语位于重读的操作词之前。本句中的is需要重读。

例如：

I will always remember you. will弱读。

I always will remember you. will 重读。
