4.名词的复数形式(2)

如果名词单数词尾为-f或-fe(读作/f/)，则其复数一律变为-ves (读作/vz/)，即将-f或-fe变成-v，再加-es而成，如housewife ---- housewives。

英语中有一些名词的复数形式是不规则的，如man与woman其复数形式分别为men与women。此外还可用man，woman等来区别阳性与阴性：以-man结尾的一些复合名词指男性，如milkman---- milkmen，policeman---- policemen;一些以-woman结尾的名词指女性，如postwoman ----postwomen，policewoman ---- policewomen。
