名词是表示人、事物、地点或抽象概念的名称的词，可以用数量来计算的名词为可数名词。可数名词一般有单数和复数两种形式。
可数名词的单数，我们可以用 ‘a’ 或‘an’来修饰，当一个可数名词是以元音因素开头的话用‘an’。例如: a cake, an egg, an range。 可数名词的复数形式变化如下：
① 一般在名词词尾加-s。如：cakes, pens;② 以s, x, ch, sh结尾的名词的词尾加-es。 如：watches, wishes, bxes …③ 以辅音字母+y结尾的名词改y为i再 加-es。如：stries, cities …④ 以f或fe结尾的名词改f或fe为v再加-es。 如：shelves, knives …⑤ 以辅音字母+结尾的名词在词尾加-es 或者加-s。如：tmates, ptates, pians, radis …
有些名词的复数变化是不规则的。child---children wman---wmenman---men ft---feet tth---teeth gse---geese Chinese---Chinese sheep---sheep一般无法用数量来计算的名词为不可数名词。不可数名词前面不能用表示具体数量的数词或不定冠词a, an, 可用一些量词,如：a packet f, tw bags f, fur kils f, three cups f等。
