名 词一、名词的数
可数名词都有单数和复数之分; 不可数名词没有复数形式。
1. 可数名词。
(1)规则的可数名词的复数变化规则: (2)不规则的可数名词的变化规则:
有些可数名词的复数形式没有规则, 不能在其后加-s或-es。不规则复数形式主要有如下几种情况:
①变内部元音字母:
man—men woman—women
tooth—teeth foot—feet
mouse—mice goose—geese②词尾加-(r)en:
child—children ox—oxen

sheep deer Chinese Japanese
④man, woman修饰复数名词, 将man, woman和名词中心词都变为复数:
a woman doctor—women doctors
a man teacher—men teachers【易错提醒】
