单复数变化规律
1、直接加s型:普通单词在单数形式后直接加-s
例如:map—maps地图 bird—birds鸟
2、s尾型:以s,z,x,sh,ch结尾的名词,需在后面加-es
例如:box—boxes盒子 class—classes班级
3、y尾型:以辅音字母加y结尾的词,变y为i再加-es
例如:baby—babies婴儿 family—families家庭
元音字母加y结尾的直接加-s
例如:boy—boys男孩 toy—toys 玩具
4、o尾型:无生命的名词后面加"-s"
例如:photo—photos相片 zoo—zoos动物园
有生命的名词后面加"-es"
例如:potato—potatoes土豆,tomato—tomatoes西红柿
5、f尾型:以fe或f结尾的名词,把fe或f变为v加"-es"
例如:knife—knives小刀 leaf—leaves树叶
6、同形型:有少数单词单复数同形
例如:sheep(绵羊),fish(鱼)
7、不规则型:有一部分单词的复数是不规则变化
例如:man-men(男人),woman-women(女人)
