名词单复数
一、定义：名词可以分为可数冥河不可数名词，不可数名词没有单复数，一律看作单数。
二、可数名词：
（1）可数名词前的量词：可数名词的单数前什么时候用a，什么时候用an?
以元音音素开头的用an，以辅音音素开头的用a。
一、选择用a或an或不填（用/表示）
______pen ______bag _____apple ______big apple
______banana _______orange _____oranges _______orange pen
（2）可数名词单数→复数的变化规则：
●一般在词尾加s，如：books,bags,girls,maps,pens
●以s、x、z、ch、sh结尾的名词加es,如classes 、boxes 、buses 、watches ●以辅音字母加y结尾的名词，变y为i，在+es，如：family -families、baby-babies ●以元音字母加y结尾的名词直接在词尾+s，如：boy-boys、day-days、toy-toys ●以辅音+o结尾的名词，词尾+es，如：tomato-tomatoes、potato-potatoes
但某些却是+s，如：photo-photos、kilo-kilos
●以元音+o结尾的名词，词尾+s，如：zoo-zoos、radio-radios、kangaroo-kangaroos ●以f、fe结尾的名词变f、fe为ves，如：wolf-wolves、wife-wifves、life-lives、

Foot-feet goose-geese mouse-mice
（4）单复数同形的名词有：
Chinese 中国人Japanese 日本人sheep 绵羊deer 鹿fish 鱼
People 人
注意：（1）fish：①当一条鱼讲时：单复数同形，如three fish;
②当各种各样的鱼讲，即强调鱼的种类时，要加es,如：all kinds of fishes
③当鱼肉讲时，不可数。
（2）people:当people后加上s，即peoples时，表示“民族”
如：There are 56 peoples in China.
