able词组

常见“able”核心词组分类解析

一、表能力:“be able to”及相关变体

“be able to”是最基础的“able”词组,意为“能够,会”,强调通过努力或具备某种能力完成某事,可用于多种时态,区别于只能用现在时和过去时的“can”“could”。

  • be able to do sth.:常规表达,例如“She is able to speak three foreign languages fluently.(她能流利地说三门外语。)”
  • be able to have done sth.:对过去虚拟的表达,指本来能够做某事却没做,比如“I was able to have finished the task ahead of time, but I got sick suddenly.(我本可以提前完成任务,但突然生病了。)
  • be well able to do sth.:强调完全有能力做,带有“绰绰有余”的语气,例如“He is well able to handle this challenging project on his own.(他完全有能力独自处理这个有挑战性的项目。)”

二、表可能性:“likely/unable to”等衍生词组

这类词组围绕“能否实现某件事”展开,侧重客观或主观的可能性判断。

  • be unable to do sth.:“be able to”的否定形式,意为“不能,无法”,比“can't”更正式,常用于书面语,例如“The rescue team was unable to reach the remote village due to heavy snow.(由于大雪,救援队无法抵达那个偏远村庄。)”
  • be unlikely to be able to do sth.:双层否定表可能性低,指“不大可能能够做某事”,例如“Given the tight schedule, we are unlikely to be able to complete all the work today.(考虑到时间紧迫,我们今天不大可能完成所有工作。)

三、表适应性:“be able for/to”的特殊用法

在部分英式英语语境中,“be able for/to”可以表示“胜任,适合”,侧重对任务、环境的适配能力。

  • be able for sth.:例如“I'm not sure if he is able for the demands of this high-pressure job.(我不确定他能否胜任这份高压工作的要求。)”
  • be able to sth.(省略do的口语化表达):口语中偶尔会省略“do”,直接接名词,比如“She's able to the job, don't worry.(她能胜任这份工作,别担心。)”,不过这种用法仅限非正式场景。

四、表潜在能力:“enable”相关词组(“able”的动词衍生)“enable”是“able”的动词形式,意为“使能够,使成为可能”,相关词组常体现“赋予能力”的逻辑。

  • enable sb. to do sth.:核心搭配,例如“Advanced technology enables us to communicate with people around the world instantly.(先进科技让我们能够和世界各地的人即时沟通。)”
  • enable sb. for sth.:表示为某事做好准备、赋予能力,例如“The training program will enable the new employees for their upcoming duties.(这个培训项目会让新员工做好迎接本职工作的准备。)
