1.直接加s。2.以s,sh,ch,x结尾的单词要加es。3.以辅音字母加上y结尾的单词,去掉y加上ies.4.以o结尾的名词，变复数时，大多数都是直接加s,除了hero,negro,potato,tamato这四个加es.5.以f或fe结尾的名词变复数时,可以是加s，如：belief-beliefs，roof-roofs;也有去f,fe加ves，如half-halves,knife-knives,leaf-leaves,wolf-wolves,wife-wives,thief-thieves.此外。还有一些不规则变化。对于像man结尾的词：man→men一些以man,woman结尾的合成词，构成复数时与man的变化形式相同，如：policeman→policemen警察但是human(人)，German(德国人)不是合成词，其复数不能仿man的变化规律，而是按规则变化，即用humans,Germans。另外，当man用于名词前作定语时，若其后被修饰的名词为复数，则man也要用复数：mannurse→mennurses男护士希望对你有帮助！
