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 85 twenty-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 365 two 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

2、时，必须用单数。如： several hundred year s ago 几百年前 two thousand students 两千个学生 2. 基数词的特殊用法：（1）表示 “ 几十年代 ” 或“ 几十岁 ” 时，用逢十的基数词的复数形式。如： in the 1990s 20 世纪 90 年代 in ones twenties 在某人 20 多岁时（2）用在习语中。如： in twos and threes 三三两两地二. 序数词序数词应注意的几点事项： 1. 多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： forty-two 42 forty-second

3、第 42 nine-hundred 900 nine-hundredth 第 900 2. 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 21 32nd 第 32 3. 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

4、eat a fourth one. 那只小猴子已经吃了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 second a third = one third （4）当分母是2和 4 时，分别可以用half 和 quarter 代替。如： a half 二分之一 three quarter

5、s四分之三 2. 百分数百分数用 percent 表示。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。精品资料 - - - 欢迎下载 - - - - - - - - - - - 欢迎下载 名师归纳 - - - - - - -

7、ize of the moon. 2. 表示 “ 比 大几倍 ” ，由“ 倍数 +形容词（副词）比较级+ than +被比较部分 ” 结构组成。如： This box is three times bigger than that one. 3. 表示 “ 是 倍” ，由 “ 倍数 + as +形容词 + as +被比较部分 ” 结构组成。如： Our factory is twice as big as theirs. 练习( ) 1.
