power的基本意思是“力,力量”,可指人的體力、思維能力,也可指機(jī)器的功力、動力或功率,還可指人或國家甚至是某個機(jī)構(gòu)的權(quán)力、勢力或影響力。這種權(quán)力或影響力可由法律、規(guī)章所賦予,也可由于本身力量的強大而自然產(chǎn)生的。power作“強國”解時,一般指在政治、經(jīng)濟(jì)或軍事等方面對世界有一定影響的大國或強國。power還可用于數(shù)學(xué)方面,作“冪,乘方”解。
power作“權(quán)”“權(quán)力”“勢力”“政權(quán)”“功力〔率〕”解是不可數(shù)名詞; 表示“強國”“冪,乘方”時是可數(shù)名詞; 表示“能力”時有時可用于復(fù)數(shù)形式,表示“體力,力量”解時通常用作不可數(shù)名詞。

當(dāng)“power”前面有“a”或者“the”時，后面接動名詞比較常見。she used to have a powder of being late. 她曾經(jīng)有權(quán)利晚到。
當(dāng)“powder”前面沒有“a”或者“the”時，后面則接“不定式”。She used to have powder to be late.
有些表達(dá)方式中，power常用復(fù)數(shù)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。
