网友的疑惑似乎是关于动词face的用法。《麦克米伦词典》的如下解释可能会帮助解惑。即A faces B与B faces A意义基本相同。例如：a person faces a problem大约等于a problem faces a person. 及物动词可以用被动结构：a person is faced with a problem/by a problem,用by为被动语态，用with为系表结构，过去分词faced作表语，with介词短语为工具状语。a problem is faced by a person. 被动语态。翻译的时候应灵活处理，考虑汉语的表达习惯。人面对一个问题，但说一个问题面对人则不符合汉语表达习惯，可译为一个问题摆在人的面前。但英文的意义是基本相同的。

如果用现在分词作定语，可以是a person facing a problem, a problem facing a man. 翻译成汉语时，不一定非得翻译为汉语的定语，可以根据汉语习惯翻译定语从句。前者可以译为一个人所面对的问题，后者和译为摆在一个人面前的问题。网友认为“挑战面临工业”不通顺，是过于拘泥于英文的句式，属于我们常说的“死译、硬译”，其实完全可以译为“工业所面临的挑战”。
