英语名词单数变复数口诀(一) 规则变化名词单数变复数,直接加-s 占多数;s, x, z, ch, sh 来结尾,直接加上-es;词尾是 f 或fe,加-s 之前先变ve;辅母+ y 在词尾,把y 变i 再加-es;词尾字母若是o,常用三个已足够,要加-es 请记好,hero, tomato, potato。
(二) 不规则变化男人女人 a 变e,鹅足牙oo 变ee;老鼠虱婆也好记,ous 变ic;孩子加上ren,鱼鹿绵羊不用变。
【解说】1. 英语名词有单数和复数的区别,单数表示“一”,复数表示“多于一。
”名词由单数变复数,多数是规则的变,直接加-s,例如:book →books, girl →girls。
但以-s, -z, -x, -ch, -sh 结尾的名词,变成复数时加-es, 例如:bus →buses, buzz →buzzes, box →boxe s, watch →watches, brush →brushes2. -f(e) 结尾的名词单数变复数歌诀:①树叶半数自已黄,妻子拿刀去割粮,架后窜出一只狼,就像强盗逃命忙。
②妻子持刀去宰狼,小偷吓得发了慌,躲在架后保己命,半片树叶遮目光。
例如:leaf (树叶,叶子),half (一半),self (自已),wife (妻子),knife (刀子),shelf (架子),wolf (狼), thief (窃贼,强盗) 和life (生命),这些名词变成复数时,都要改-f (e) 为v,再加-es。
3. -f 结尾的名词直接加-s 变复数歌诀:海湾边、屋顶上,首领奴仆两相望;谁说他们无信仰,证据写在手帕上。
例如:gulf, roof, chief, serf, belief, proof, handk erchief,这些名词变复数直接加-s。
注:scarf(围巾;披风) 可以先改 f 为ve 再加-s,也可直接加-s。
4. 辅音字母+ y 结尾的名词,把y 变i 加-es。
