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 o 结尾且表人或农作物等有生命事物 的词在词尾加 -es 。如： tomatoes, potatoes…
