leaf-leaves(树叶) scarf-scarves/scarfs(围巾) handkerchief-handkerchieves/handkerchiefs(手帕) knife-knives(刀子) thief-thieves(小偷) life-lives(生命) self-selves(自己,myself-ourselves) half-halves(一半) wolf-wolves(狼) f结尾的名词变复数,是变f为v再加-es,还是在f后直接加-s,可用两首打油诗来帮助记忆: (A) thief,wolf,knife, 贼狼刀,贼狼刀; shelf,self,wife,loaf, 书架自己的妻子吃面包; elf,sheaf,leaf, 小精灵(有)一捆树叶; calf,life,half, 小牛(的)生命一半了. (B) “妻子”遇“狼”拿起“刀”, 吓得“强盗”满街跑; 碰到“架子”“毁”己“命”, “手帕”“树叶”“半”空飘. 注: 以上被引号引入的部分,皆为以“f”或“fe”结尾的名词,如变为复数一律先变“f”或“fe”为“v”加上“es”读[iz].例如: wife—wives,wolf—wolves, knife—knives,thief—thieves, shelf—shelves,self—selves, life—lives,handkerchief—handkerchieves, leaf—leaves,half—halves 其中handkerchief还可以有加“-s”形式:handkerchiefs. 另外,在中学课本中出现了四个以f结尾的单词是由加“-s”构成复数.这四个词是:belif,gulf,roof,serf(农奴).记住:The serf had thebelief that there is a gulf in his roof
