扩展资料
名词复数的不规则变化
1）child---children foot---feet tooth---teeth、mouse---mice man---men woman---women
注意：与 man 和 woman构成的合成词,其复数形式也是 -men 和-women.
如：an Englishman,two Englishmen.但German不是合成词,故复数形式为Germans；Bowman是姓,其复数是the Bowmans.
2）单复同形 如：
deer,sheep,fish,Chinese,Japanese
li,jin,yuan,two li,three mu,four jin
但除人民币元、角、分外,美元、英镑、法郎等都有复数形式.如:
a dollar,two dollars; a meter,two meters
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 people,a police,a cattle,但可以说
a person,a policeman,a head of cattle,the English,the British,the French,the Chinese,the
Japanese,the Swiss 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.
