名词单数变复数的方法
名词单数变复数的方法1. 基本变化规则①一般在名词后加s，变成复数。
如boy→boys, pen→pens等。
②以s, x, sh, ch结尾的，在后面加es。
如class→classes, fox→foxes, brush→brushes, watch→watches。
但stomach的复数为stomachs。

如baby→babies。
④以f或fe结尾的名词英语中共有100多个，其中直接加s的有92个，但这些绝大多数不常用，如safe, roof, belief等；把f或fe改为v, 再加es的只有13个，但13个都是常用的名词，如thief, life, wife, shelf, self, knife, half, leaf, wolf等。
⑤以o结尾的名词，除有生命的“两人两物”Negro, hero, tomato, potato等少数在后面加es 外，一般是在后面直接加s。
如kilo→kilos, photo→photos, zoo→zoos, radio→radios, piano→pianos, video→videos。
2. 不规则变化名词单数变复数的不规则变化要注意以下几点：①含man的名词，一般变man为men。
如woman→women, policeman→policemen, Englishman →Englishmen。
但German→Germans。
②将oo改为ee的有foot→feet, tooth→teeth, goose→geese等。
③复数以en结尾的有child→children, ox→oxen等。
④将ouse改为ice的有mouse→mice, louse→lice(虱子)等。
⑤单复数同形的有sheep, deer, fish, means, works(工厂), Swiss, Japanese,Chinese等。

”名词由单数变复数，多数是规则的变，直接加-s，例如：book→books，qirl→gir ls。
