用法辨析

    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。
  • focus on sth表示“集中于某事”；
  • focus作“中心，焦点”的解释时，用词范围很广，常被滥用，需注意。
