2) s,sh,ch,x等结尾的词加es,如bus→buses watch→watches

注意:四个以o结尾加es变复数的单词:黑人negroes,英雄heroes,土豆potatoes,西红柿tomatoes 口诀:“黑人英雄爱吃土豆西红柿”

3) ce,se,ze,(d)ge等结尾的词加s,如license→licenses

4) 以辅音字母+y 结尾的词变y i再加es,如baby→babies

注意:以元音字母+y结尾的词直接加s变复数,如 boyboys; keykeys

5)以“f”,"fe"结尾,把ffe改成 v + es,如wife→wives

2 不规则变化

1)child→children foot→feet tooth→teeth mouse→mice man→men woman→women

2)单复同形

3)集体名词,以单数形式出现,但实为复数。 如: people police cattle 等本身就是复数,不能说 a peoplea policea cattle 可以说 a persona policemana head of cattle(一头牛)

the Englishthe Britishthe Frenchthe Chinesethe Japanese等名词,表示国民总称时,作复数用。

如: The Chinese are industries and brave. 中国人民是勤劳勇敢的。 4s结尾,仍为单数的名词,如:mathspoliticsphysicsnewsthe United Statesthe United Nations 是单数。 如:The United Nations was organized in 1945. 联合国1945年组建起来的。

5) 表示由两部分构成的东西,如:glasses (眼镜) trousers, clothes 若表达具体数目,要借助数量词, a pair of glasses; two pairs of trousers a piece of clothes.

其他需要借助数量词表达具体数目的名词短语:a cup of tea/coffee/water; a bottle of milk/ juice/ ink; a piece of advice/suggestion/ bread/ cake/ paper/news; two drops of ink(两滴墨水)
