  • 词源解说

v.(动词)
  • focus用作名词时原始意义是“火炉”,引申为“焦点”,转化为动词则为“(使)聚焦”,“(使)集中”。即“调整…的焦点或焦距以便看清”,引申则表示“使(注意力等)集中于某物”。
  • focus用作及物动词时,可以接望远镜、焦点等作宾语,也可以接阳光等作宾语,还可以接目光等作宾语。focus用于比喻作“致力于”解时,则可以接mind, attention等作宾语。
  • focus也用作不及物动词,这时常和介词on连用,表示“聚焦于…”“致力于…”等。
v.(动词)
focus, centre, centralize, concentrate
  • 这组词的共同意思是“集中”。其区别在于:centre强调事或物所集中的那个中心点; focus强调同类事物汇集在一点上,融成一体; centralize则用于那些能集中又能分散的事或物,尤指集中权力或类似的东西; concentrate强调人类为达到目的而采用的技巧和方法、纪律及为此所做出的努力。例如:
  • The conversation was centred on the election.会谈的中心问题是选举。
  • The troops concentrated near the station.部队集结在车站附近。
  • He focused the sun's ray on a piece of paper with a burning-glass.他用一面凸透镜把阳光在纸上集成焦点。
