1、数词数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。一 . 基数词1. 基数词就注意以下几点：（ 1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如：eighty-five 85twenty-six 26（ 2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and 连接。如：three hundred and sixty-five 365two hundred and six 206（ 3）基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或 several 修饰时，必须用单

3、red 900 nine-hundredth 第 9002. 当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如：21st 第 2132nd 第 323. 序数词前一般要用定冠词the，如果序数词前用a 或 an 时，则表示 “又一；再一 ”（没有具体范围的限制） 。如：Though he had failed twice, he wanted to try a third time.尽管他已失败了两次，他还想再试一次。The little monkey had had three apples, and he wanted to eat a fourth one.那只小猴子

4、已经吃了3 个苹果，他还想再吃一个。三 . 分数和百分数1. 分数（ 1）分数的分子用基数词，分母用序数词。如：one fifth 五分之一one tenth 十分之一（ 2）当分子大于1 时，分母用序数词的复数。如：two thirds 三分之二five eighths 八分之五（ 3）当分子是1 时，可以用one 也可以用a。如：a second = one seconda third = one third（ 4）当分母是2 和 4 时，分别可以用half 和 quarter 代替。如：1a half 二分之一three quarters 四分之三2. 百分数百分数用percent 表示

5、。如：forty percent 百分之四十three percent 百分之三3. 分数、百分数与主谓一致分数、百分数的考查往往和主谓一致相联系。当分数、 百分数修饰可数名词的复数时，谓语动词用复数形式；当分数、百分数修饰不可数名词时，谓语动词用单数形式。如：Eighty percent of the students in our school come from Henan.我们学校百分之八十的学生来自河南。Three fourths of the students in my class are interested in English.我们班四分之三的学生对英语感兴趣。Two th
