专有名词和普通名词，名词单数变复数规则及练习
名词
一、英语名词可分专有名词和普通名词两大类：
1、专有名词是个别的人、地、物、团体、机构等的专用名称。专有名词中实词的第一个字母要大写。
如：Beijing, Tom, the People’s Republic of China(中华人民共和国) 专有名词如果是含有普通名词的短语,则必须使用定冠词the。如：the Great Wall(长城)
姓氏名如果采用复数形式,则表示该姓氏一家人(复数含义),如：the Greens( 格林一家人)。
2、普通名词是许多人或事物的共有名称。如：pupil, family, man, foot.
普通名词又分为可数名词和不可数名词。
▲可数名词是可以用简单的数词进行计数的名词,如：box, child, orange；
▲不可数名词是不可以用简单的数词进行计数的名词。如：water, news, oil, population, information . 二、英语可数名词的单复数：
1、名词由单数变复数的基本方法如下：①一般情况，在词尾加-s.
desk---desks 书桌girl---girls 女孩boy---boys pen---pens ②以-s,-x,-ch,-sh 结尾的词，在词尾加--es
bus---buses box--boxes brush--brushes watch--watch ③以辅音字母加-y结尾的词，变y为i，加-es baby-babies 婴儿family--families家庭④以-f或-fe 结尾的词，变f或fe为v，再加-es knife---knives刀leaf---leaves树叶
⑤以-o结尾的词，一般情况下，在词尾加-s，黑人英雄吃西红柿土豆除外。
photo---photos piano---pianos
negro---negroes 黑人hero---heroes 英雄tomato---tomatoes西红柿potato--potatoes马铃薯2、不规则变化：
man→men, woman→women, sheep→sheep, tooth→teeth, fish→fish, child→children, ox→oxen, goose→geese
三、不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。如：a bag of rice→two bags of rice, a piece of paper→three pieces of paper, a bottle of milk→five bottles of milk.
