    词源词根法
    来自拉丁语focus,火炉,引申词义家,集中点。在1604年德国数学家Johannes Kepler用该词来指数学意义上的聚焦。进一步可能来自PIE*bhe,照明,发光,词源同beacon这个常用词原本是拉丁文,借用时完全保留了原来的拼写形式,在拉丁语中作“壁炉”或“壁炉边”解。古罗马耐代壁炉边即focus被认为是家庭生活的中心。拉丁语族一些语言中表示“火”的词,如法语feu,西班牙语fuego+意大利语fuoco等,均源自focus一词。focus的现代词义是德国天文学家开普勒(Johannes Kepler,1571-1630)在1604年首先使用的。他用它表示。焦点”。以后该词在英语里还被用来表示“焦距”,也喻指“(注意、活动、兴趣等的)中心”,除了用作名词,也可用作动词,表示“聚焦”、“集中”等义。=拉丁语中focus指“壁炉”、“火”,因而派生了英语fuel和fusillade;其现代意义也许来自于“壁炉的炉膛是家的中心”或“镜子的燃烧点”;拉丁语focus进入法语为foyer(炉膛、家庭),被英语借用后,意义变为“走廊,大厅,休息室”。

    小知识

    Focus is something that camera lenses and sleepy students are always being asked to do. For cameras, it means finding a point where the subject is clear or “in focus.” For students, it means paying attention.

    Focus is all about finding a center — of a parabolic curve, of a lens, of a meditative state. In Latin, focus meant 'domestic hearth,' which just goes to show that not much has changed — since kitchens remain the focus of the modern home. Focus can be used as a verb, as in “I need to focus on my work, so I can play video games later;” and as a noun, as in “What is the focus of this essay? I can't tell, since the writer seems to be all over the place.”
