1)单数名词加s: students, apples, bags, trees, books, brothers.
2)以s、x、sh、ch结尾的名词加es: glasses, boxes, brushes, matches.
3)以辅音字母加y结尾的名词,变y为i加es: cities, babies, enemies.
4)以f或fe结尾的名词,多数变f为v加es: wives, knives.但有些词只加s: roofs, proof s, chiefs.
5)以o结尾的名词,有些加es: Negroes, heroes, tomatoes, potatoes.其它加s: radio s, zoos, pianos, photos.

6)不规则名词:foot→feet, goose→geese, tooth→teeth, child→children, man→me n, woman→women, sheep→sheep, deer→deer, mouse→mice.
7)某些外来词变复数:datum→data, medium→media, bacterium→bacteria, curriculum→curricula, criterion→criteria, phenomenon→phenomena. (um/on→a)analysis→analyses, basis→bases, crisis→crises, diagnosis→diagnoses.(is→es )
8)复合名词变复数:以不可数名词结尾的复合名词无复数形式,如:homework.
以man或woman为前缀的复合名词变复数,前后两个名词都变复数,如:manservant→menservants, woman student women students.
其它复合名词变复数:grownup→grownups, brotherinlaw→brothersinlaw, standby→standsby.
9)复合形容词做定语时,其中的名词保持单数:a sixyearold boy,a twohundredpage book

一般情况,直接加s,如desks
以s或x结尾的,加es 如buses,boxes
以o结尾的有tomato,hero,potato是加es,其他都加s,如zoos,photos
以辅音字母加y结尾的,把y改i,再加es,如baby-babies,以元音字母加y结尾的,直接加s,如keys
以f,fe结尾的有的直接加,如roof→roofs
有的把f,fe改为ves,如knife--knives
还有一些特殊的,就得记了,象foot--feet,
