英语中的数词分为基数词和序数词。基数词表示数目，序数词表示顺序，即表示事物顺序的词,其前常加定冠词the。英语中，表示数量的词叫基数词。1.one~twelve(1-12)的拼写和读音各不相同，无规律可循，应逐一记忆。2.thirteen~nineteen(13-19)表示“十几”，在个位数词后加后缀-teen,读作[ti:n]，单词有两个重音。还要注意thirteen(13)、fifteen(15)和eighteen(18)在拼写上的差别之处。语法专讲1基数词3.twenty~ninety(20-90)表示“几十”，几十的整十位数是在个位数后加后缀-ty,读[ti]。但要注意加了-ty之后，个位数上的听定就有变化。eg：twenty(20),thirty(30),forty(40),fifty(50)...4.21-29直到91-99表示“几十几”，用整数十位数加个位数，中间用连字符“-”把整十位数加个位数，中间用连字符“-”把整十位数和个位数连起来。eg：twenty-three(23);thirty-seven(37);forty-five(45);fifty-two(52);sixty-one(61);seventy-three(73);eighty-four(84);ninety-nine(99).语法专讲1基数词拓展:1.onehundred“一百”，表示“一百”用ahundred。要表示200-900，用“数词（two至nine）+hundred”构成。在此结构中，无论“几百”，hundred都不能加-s变复数形式。

500fivehundred600sixhundred拓展2：hundredsof+复数名词或代词宾格是固定结构，表示“数以百计的”、“成千上万的”在此结构中，hundredsof前面不能加数词，hundredsof后面只能用复数名词或复数代词宾格形式。eg：hundredsofteachers成百上千的教师hundredsofthem他/她/它们中数以百计的（人和物）语法专讲1基数词3.101—999，三位数，百位与十位/个位之间加and。101onehundredandone840eighthundredandforty693sixhundredandninety-three4.1,000以上数目,从右向左每三位用“，”分开,分别读为thousand千,million百万,billion千万语法专讲1基数词29,43150076,,thousandhundredmillionbillionand

英语基数词顺口溜英语数词不难记，找出规则就容易。零至十二形各异，一个一个单独记。后面加teen变十几，thirteen,fifteen看仔细。eighteen只有一个t，两个音节念清晰。表示“几十”要加-ty,twenty,thirty是特例。表示数字“几十几”，连字符号别忘记。

英语中的数词分为基数词和序数词。基数词表示数目，序数词表示顺序，即表示事物顺序的词,其前常加定冠词the。

【记忆口诀】基变序，有规律，多数词尾加-th。一、二、三特殊记，词尾字母t,d,d。八去t,九去e,字母f把ve替，然后再加-th。遇到几十几，只变个位就可以。序数词表顺序，一般须加定冠词。
