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 orange。 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, boxes …
③ 以辅音字母+y结尾的名词改y为i再
加-es。如：stories, 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+o结尾的名词在词尾加-es
或者加-s。如：tomatoes, potatoes,
pianos, radios …
有些名词的复数变化是不规则的。
child---children woman---women
man---men foot---feet
tooth---teeth goose---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 of, two bags of, four kilos of,
three cups of等。
two bags of rice
a packet of salt
a glass of juice
three cups of tea
five cartons of milk
four kilos of meat
