1.可数名词复数的变化规则.
A、一般情况下,在单数名词的后面加-s构成。如:game-games,boy-boys等。
B、以s、x、sh、ch结尾的单数名词变复数,在词尾加-es构成。如:box-boxes,bus-buses,
peach-peaches,dish-dishes。
C、以o结尾分为两种情况
①表示有生命的事物的单数名词变复数加-es;如:potato-potatoes,tomato-tomatoes等。
②表示没有生命的事物的单数名词变复数加-s。如photo-photos,piano-pianos,radio—radios ,zoo— zoos等。
D、以辅音字母加y结尾的单数名词变复数,将y改成i后再加-es。如:factory-factories,

monkey-monkeys.
E、以f或fe结尾的单数名词变复数,将f或fe改成v,然后再加-es。如:leaf-leaves,life-lives,knife-knives等。
