1、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, 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。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
2、如:bus → buses, buzz → buzzes, box → boxes,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。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。4.辅音字母+ y结尾的名词,把y变i加-
3、es。例如:baby → babies, country → countries,family → families;而-y前是元音时,-y不变,直接加-s。例如:day → days, boy → boys5.以-o结尾的名词变复数时,多数直接加-s。例如:radio → radios, piano → pianos,kangaroo → kangaroos;有的须加-es,中学课本中有几个这样的单词,可以通过一句口诀来记忆:黑人英雄爱吃西红柿和土豆。即Negro → Negroes, hero → heroes,tomato → tomatoes, po
4、tato → potatoes;(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。6.名词复数的不规则变化需要特别记忆。例如man → men, woman → women,goose → geese, foot → feet, tooth → teeth,mouse → mice, louse (虱子) → lice,child → children, fish → fish,deer (鹿) → deer, sheep → sheep等。初中课本中表示“某国人”的名词复数形式
