基数词表示数目的词，与中文中的“一、二、三”一致；序数词是表示顺序的词，与中文中的“第一、第二、第三”等一致。
基数词英语中最基本的基数词如下，其他数词都可以由这些词构成：1. 基数词1—12 : 死记硬背这十二个数词例：one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve2. 13—19: 个位数+teen 例：14: fourteen (除thirteen, fifteen ,eighteen )3. 整十位数：个位数+ty 例：60：sixty (除twenty, thirty, forty ,fifty, eighty)4. 复合基数词：整十位数+个位数twenty-one (两个词之间有连接号)5. 百位数：数词+hundred +and+整十位数+个位数+复数名词例：One hundred and fifty-five days6. 千位数：数词thousand +数词hundred ++and+整十位数+个位数+复数名词7. 百万数：用million表示，例：10 million8. 亿: 用“hundred million”表示, 例：five hundred million9. 十亿: 用“billion”表示, 例：ten billion* 注意：1. 如果数词里有零，用“and ”表示，例：三百零三；three hundred and three2. 百位数与十位数之间有"and”; 十位数与个位数之间有“-”；千位数与百位数之间没有任何修饰词。
3. 注意一些词组：hundreds of; thousands of; millions of; billions of序数词构成1. 与基数词完全不同形(1-3)：first; second; third2. 在基数词后+th (4-12)：fourth；sixth；seventh; tenth ( fifth, eighth; ninth ,twelfth)3. 十位数序数词的构成：个位数+ ty 改“y”为“ieth ”：twentieth, thirtieth4. 复合序数词只需把后一个基数词改成序数词：twenty-one：twenty-first*其中以下数词“5；9；12；14；19；40；44；50；90；99；100”很特殊，同学经常犯错，望重视这些词,他们分别是：fifth; ninth; twelfth; fourteenth; nineteenth; fortieth; forty-fourth; fiftieth; ninetieth; ninety-ninth; hundredth序数词前常有“the”；但如有形容词或定语修饰就不需“the”(1) There is a fourth boy in the playground.(2) This is my second time to come here.用法：1.日期（the fifth of March）2. 修饰名词( the first time)3. 修饰基数词（the first ten people）1.

Two fifths of the class are league members.2. Half of the population are workers. （看后面的名词决定谓语的单复数）3. Three quarters of the water is sea water.百分数（per cent）30% 30 per cent百分数作主语，注意谓语的单复数形式1. Sixty per cent of the students have passed the exam.2. 70 per cent of the earth is covered by water.数词应注意以下几点：1. 固定词组hundreds of ; thousands of ; millions of ; billions of当前面有数词修饰这些词时，“hundred; thousand; million; billion” 不能用复数例：two hundred students; thirty thousand people没有数词修饰时，这些词常用复数（除several）例：many hundreds of toys; millions of people注意下面特殊句：Several hundred of the students are working hard now.Five hundred of the people will be invited to the party.2. 数词的其他用法：Lesson 15 = the fifteenth lessonRoom 203 Channel 6 n.+基=定+序+n.April 10, 2003 April the tenth，2003The last 3 pages the first 5 minutesthe No. 16 busin one’s +整十位数的复数形式in his twentiesin the 1930s in the nineteen thirties3. 序数词前一般用定冠词，有时可用不定冠词（意义不一样）He wanted to pay a second visit to our countryShall I ask him a third time ? 还要问他第三次4. 当一个基数词和一个序数词同时修饰一个n.时，序数词一般位于基数词之前，例：The first three sentences need to be read againThe second five pupils are from class one .三个一等奖three first prizes first three prizes 前三个奖5. 年份、日期、时刻的表示法1）年份1600—sixteen hundred 1949—nineteen forty-nine1970 / 1970’s—nineteen seventies2) 序数词表日期May 23—May the twenty-third or the twenty-third of May3) 日期的书写用序数词也可用基数词，说话用序数词4) 倍数的表示法……timesa……..times +名词短语The size of shanghai is five times the size of that city .b……..times+形容词比较级……four times larger than ……c…….times + as + 形+ asd ……five times as big as5) 大于more than , over / aboveabove 20 degrees小于less than ……under / belowless than 2 hours ; the boy under 6Sell it below 100 dollars数词的相关练习根据相对应的中文，完成句子1.

英语数词的使用方法
英语数词的使用方法数词是指表示数目多少或顺序先后的词。
表示数目多少的数词叫基数词，如 one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词，如 first, sixth, tenth, twenty-first 等。
数词用法相当于名词和形容词，在句中可用作主语、宾语、表语、定语、同位语等。
1. 英语中没有“万”这个读数单位，要表示汉语中的“万”，英语需借用thousand一词，如“一万”用“十个千”表示(ten thousand)，“十万”用“一百个千”表示(one hundred thousand)。
2. 用作基数词单位的 hundred, thousand, million, billion 通常不带复数词尾-s，但假设用于表示数百、数千、数百万这样的泛指，那么用复数。
如：About two thousand people died in the earthquake. 大约有两千人在地震中丧生。
Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。
3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。
如：He is in his early twenties. 他才二十出头This took place in the 1930s. 这事发生在20世纪30年代。
1. 许多序数词是由相应的基数词后加词尾-th构成的，如four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nih。
2. twentieth, thirtieth, fortieth 等表示整十的序数词，由相应的基数词将词尾y改为ie，再加-th 构成。
3. first, second, third 通常可缩写为1st, 2nd, 3rd。
