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。

She is trying to centralize all power into her own hands.她力图把所有权力集中在自己手中。concentrate，focus这两个动词均有“集中，聚集”之意。 concentrate指把人或物集中在一起，也可指把精力或注意力集中于某一事物上。 focus侧重指把光、热、射线等集中于一点，也可指把思想或精力等集中于某人或某事情上。 17世纪40年代进入英语，直接源自古典拉丁语的focus，意为炉床，壁炉。

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。
