juice water milk rice people CD ox deer fish

Answer 1

cities zoos countries teeth mice boys brooms cars
trees horses buses foxes babies families dishes radios photoes pianos knives
leaves lifes thieves men women children feet these watches diaries days
books dresses sheep(集合名词) tea（不可数名词）boxes strawberries peaches sandwiches papers
juice（不可数名词）water（不可数名词）waters水域、海域 rice（不可数名词） people 集合名词 CDs oxen deer(集合名词) fishes
首先分清时可数名词还是不可数名词，如果是不可数名词，就没有复数形式。但是，有些单词不同语意有不同的性质，比如life 作生活和生命就不同，有时没有复数形式。
另外，有一些名词从它产生表示的就是复数意思，它没有单数形式。
有些固定结尾有固定的复数形式改法，加es，s就可以了，有些以fe,f结尾的需要改为ves,以y结尾有些需要改为ies，还有一些特殊的单词中oo改为ee，还有一些就只能纯粹的去记了。比如oxen,looker(s）-on，women doctors
