用法辨析

    n. (名词)

  • power的基本意思是“力,力量”,可指人的体力、思维能力,也可指机器的功力、动力或功率,还可指人或国家甚至是某个机构的权力、势力或影响力。这种权力或影响力可由法律、规章所赋予,也可由于本身力量的强大而自然产生的。power作“强国”解时,一般指在政治、经济或军事等方面对世界有一定影响的大国或强国。power还可用于数学方面,作“幂,乘方”解。
  • power作“权”“权力”“势力”“政权”“功力〔率〕”解是不可数名词; 表示“强国”“幂,乘方”时是可数名词; 表示“能力”时有时可用于复数形式,表示“体力,力量”解时通常用作不可数名词。
  • power作“权力”“能力”“动力”解时后面可接动词不定式作定语。

    • v. (动词)

  • power的基本意思是指向飞机、雷达、汽车等提供原动力,此时是及物动词,接名词或代词作宾语,可用于被动结构。引申可表示“飞速行驶”,此时作不及物动词。
  • 当“power”前面有“a”或者“the”时，后面接动名词比较常见。she used to have a powder of being late. 她曾经有权利晚到。
  • 当“powder”前面没有“a”或者“the”时，后面则接“不定式”。She used to have powder to be late.
  • 有些表达方式中，power常用复数形式powers，如his powers of mind, his powers of observation, his powers as a novelist, a novelist at the height of his powers等。
