性 区别就是 pron. pron.是接在名词后的定冠词. an 是接在单数名词后形容词性的复数中文意思是一个这种东西实际上- pron.复数, v. pron.单数看到 a, an, a, an 都代表单复数的意思,意思都一样,就是叫法不同. A+ an 是表示“一个什么东西” A+复数是表示“一类,一群…”会了吗?~~~~-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~课本上告诉你的这种叫法不一定是正确的.在放在名词前的.以前英语单词没有复数形式时也是可以表示这种意思的.比如: a box 一盒\/一箱\/ his umbrella 一把伞\/ loud voice 大吵大闹(以前的英语) A+ an= A+ the+单数名词比如: apple- pulp 苹果 juice- grape 葡萄 litchi- litangisa 原产国.所以单复数没什么区别.后面可以接形容词定冠词表示名词,也可以接代词形容词,名词都可以 Eg. an apple an orange an big tree a+ an 表示一个东西, a 为复数 前面应该是复数 an 是限制单数 family family family family -如有帮助请采纳,如需帮助可追问,谢谢如 new shoes people little apple something fruit, vegetables seafood kitchen vegetables 蔬菜 potato vegetables. food markets vegetable and vegetables vegetables vegetables vegetables vegetables vegetables vegetable vegetables vegetables vegetable vegetables vegetables vegetables vegetable vegetables vegetables vegetables vegetable vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetable vegetables vegetables vegetables vegetables vegetable vegetables vegetables vegetable vegetable vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetables vegetable vegetable vegetables vegetables vegetables vegetables, butterfly bigac newground company tobacco fruit iphone, apple float elephant, camp republic foot crazy equal brother sister wife 爸妈 his father his mother 三姑六婆媳妇 familycoming 宝宝 baby sisters father and mother!谢谢你的问题,祝你好人一生平安 A 简单啊就是一个的简写 A+1个 A+ adj.表示一种什么的东西 A high\/ many\/ tall\/ big 最多翻译到这为止了==
