儒琴英语词组（English Phrase of the Day）
double down
phrasal verb
英文解释
Double down means aggressively increase a bet, investment, or commitment. The phrase alludes to doubling a bet in a card game. Double down is often used when implying that strengthen one’s commitment to a particular strategy or course of action, typically one that is potentially risky； to become more tenacious, zealous, or resolute in a position or undertaking.
中文解释
Double down是指大举增加赌注、投资或承诺。最初这个短语暗指在纸牌游戏中加倍下注。Double down 后来引申用来指加强某人对某一特定战略或行动方针的承诺，尤其指有潜在风险的战略或行动方针。韦伯词典给出的定义是：在某一立场或事业上变得更加顽强、热心或果断（to become more tenacious, zealous, or resolute in a position or undertaking）。根据上下文，可以考虑翻译成：强调，加倍，加大力度，变本加厉。
