"focus" 是英语中兼具名词和动词功能的词汇,其核心概念可追溯至拉丁语"focus"(意为"壁炉"或"家庭中心")。在现代应用中主要包含以下三个维度:
光学与物理定义
作为名词时指光线或电磁波的汇聚点,例如凸透镜使平行光线汇聚的"焦点"(focal point)。剑桥词典记载该词于1660年代首次用于光学领域。数学表达式可表示为: $$ f = frac{R}{2} $$ 其中$f$是焦距,$R$为透镜曲率半径。
认知心理学层面
动词形式指注意力集中过程,牛津大学实验心理学系研究表明,人类大脑前额叶皮层在聚焦任务中呈现显著激活特征。例如:"She focused all her energy on solving the equation."
现代引申应用
在商业管理领域,哈佛商业评论将其定义为"战略资源分配的优先级设定",如:"Our focus for this quarter is customer retention." 摄影术语中则指调整镜头清晰度的操作过程。
该词演变体现了从具象空间概念(古罗马家庭中心)到抽象认知概念的语义扩展,这种跨领域适用性使其成为英语高频核心词汇。
"Focus" 的详细释义与用法解析
词性:名词、动词

核心含义:
短语 | 含义 | 例句 |

Focus 兼具物理与抽象含义,从光学术语演变为日常高频词,体现语言与科学发展的交织。掌握其用法需结合场景(如学术、职场)与搭配(如 focus on)。在写作中,可用 in focus 增强画面感,或用 shift focus 表达逻辑转折。
