While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so. (07.6 Passage 2)

分析主干：they cannot work...

While 引导让步状语从句，“尽管......”。从句中的employ 表示“采用”，不定式to get...作目的状语。work in parallel“并行不悖地起作用”。no matter how 也引导让步状语从句，表示“无论多么......”。

译文“尽管要完成定稿这两种思维都不可或缺，可是它们却不能并行着参与写作过程-----无论我们多么认为原本如此。
