omato的名词复数,即在tomato后面加es,类似的单词还有potato→potatoes(土豆)。名词分为可数名词和不可数名词两种。可数名词通常能一个一个的数,所以有单数和复数两种形式。不可数名词
,顾名思义,不能一个一个的数,所以没有复数形式。可数名词单数变复数时,有一些是规则的,有规律可循;有一些是不规则的。(1)规则的名词复数的变化规律:一般情况下,直接在名词后面加s。dog→dogs(狗);window→windows(
窗户)以s,x,sh,ch等结尾的名词,要在词尾加es。bus→buses(公共汽车);box→boxes(箱子)以“辅音字母+y”结尾的名词,要把y变成i,再加es。library→libraries(图书馆);strawb
erry→strawberries(草莓)以o结尾的名词大多数直接加s。zoo→zoos(动物园)(tomato,potato除外)以f或fe结尾的名词,变f或fe为v,再加es。knife→knives(小刀);leaf→leaves(叶子)(2)常见的不规则名词的复数形式:
①单复数相同,例如:sheep→sheep(绵羊);fish→fish(鱼)②元音字母变化的,如:man→men(男人);woman→women(女人);foot→feet(脚);tooth→teeth(牙齿)③词尾发生变化的,如:child→c
