as后的倒装He had spent his life brewing beer for the brewery,as

今天我遇到了相同的问题,上网搜的时候看到了你这个句子.我找到三点：
比较从句的倒装：
as,than引导的比较从句中,如果主语是名词短语且较长,经常采用倒装结构(不倒装也可以).注意：这种结构主语一般为名词,如果是代词则不倒装.如：
Hydrogen burns much more cleanly than do other fuels and is easy to produce.
Today’s electric cars cannot go as fast as gasoline-driven vehicles because the battery does not offer the same amount of energy as does gasoline combustion.
Reading is to the mind as is exercise to the body.

2. 我搜这句话的时候看到了它在China Daily里一篇文章的原文--"The Brewer's Son"
3. 我在“黄冈中学2006届高三英语第二轮专题训练(三)”里看到了类似的一句,是一篇完形填空,它的答案在网页那篇文章的第三页

那么现在我自己脑子里大概有数了,可是这个问题是你那么久之前提的,希望你早已找到了自己的答案,万一如果没有的话,希望你能看到这个回复.

完整的句子就是He had spent his life brewing beer for the brewery, as had his father and grandfather before him （had spent his life brewing beer for the brewery）.
括号里的句子是前面的重复，英文中很忌讳重复，所以就省略了，大家一看就能知道是什么意...
