为什么要在这里用does?

题目

为什么要在这里用does?
The campus newspaper does not print as much world news as does my hometown newspaper.
第2个does为什么要放在这里?
我觉得该放在my hometown newspaper后头。
我只是单纯想问第2个does为什么要放在my hometown newspaper前头.

答案

你是想问为什么要用does 而不省略吗?
因为as……as 结构对称,前面比较的是 newspaper prints多少,后面就是应该是my hometown newspaper prints,这里does 代prints
The campus newspaper doesn't print as much .as my hometown newspaper prints.
这个应该不算语法点吧,如果有可能也要到研究生级别了,我英语专业的学过语法了,也没有关于这里的倒装的语法,最可能的是my hometown newspaper太长了,句子不平衡,所以把does 提上来,顺口美观吧.
