concentrate
释义
To give all your attention or effort to one thing.
集中(注意力),专心于
To bring or come together in one place; to gather in large numbers or amounts.
(使)集中,聚集于一处

词根拆分
词根派生con-(一起)+ centr(中心)+ -ate(动词)= 朝一个中心拢到一起。'聚向一点'这个画面解释了它所有义项:把注意力收拢到一件事(concentrate on work)、把人或物聚到一处(troops concentrated at the border)、去掉水分把物质精华压进更小体积(concentrate the juice)。
词根 centr 还连着 9 个词为什么是这个意思
所有含义都来自同一个动作:朝中心聚拢。当你 concentrate,是不再让注意力散开,而把它收到一点。当财富或军队 concentrate,是聚到一处而非散布。当你 concentrate 果汁,是赶走水分,让味道紧紧压在核心。同一个动作,只是被拢起来的东西不同。

易混词辨析
concentrate 与 focus —— 都指把注意力对准一件事。focus 偏向对准目标(focus on the goal),可以是一瞬间的;concentrate 强调持续地用脑、对抗干扰(concentrate for an hour)。相机用 focus 对焦,不用 concentrate。
