1.英语单词变复数基本规则
A、一般情况下，在单数名词的后面加-s构成。例如：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。例如：box-boxes,bus-buses,peach-peaches,dish-dishes, city cities,baby babies,enemy enemies。
C、以o结尾，表示有生命的事物的单数名词变复数加-es；表示没有生命的事物的单数名词变复数加-s。例如：potato-potatoes，tomato-tomatoes，photo-photos，piano-pianos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。例如：factory-factories，story-stories，family-families。
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。例如：leaf-leaves，life-lives，knife-knives等。
F、名词单数变复数，除了有规则可循的变化之外，还有一部分的变化是不规则的，我们将这部分名词的变化叫做不规则复数变化。
