如果该名词以一个辅音字母+y结尾,它的复数是去y+ies,如:family---families, baby--babies, library--libraries;
如果以f, fe结尾的名词去f或fe变成ves。如:knife-- knives, leaf--leaves;
还有就是“oo”变“ee”,如:goose--geese, tooth-- teeth;
还有一些不规则的名词,它们的复数需记忆,如:man--men, woman-- women, policeman--policemen, child--children, mouse--mice, sheep--sheep, fish--fish
