数 词：主要分为基数词和序数词两类。
一、 数词的分类
1. 基数词：表示数目的词称为基数词。
A．从 11——19除 eleven， twelve， thirteen， fifteen， eighteen为特殊形式外，fourteen，sixteen，seventeen，nineteen都是由其个位数形式后添加后缀-teen构成。
B．从 21——99整数几十中除twenty，thirty, forty，fifty，eighty为特殊形式外，sixty，seventy，ninety都是其个位数形式后添加后缀-ty构成。表示几十几时，在几十和个位基数词形式之间添加连字符“-”
21 twenty-one 76 seventy-six
C．基数词在表示确切的数字时，不能使用百、千、百万、十亿的复数形式；但是，当基数词表示不确切数字，如成百、成千上万，三三两两时，基数词则以复数形式出现。
They went to the theatre in\by twos and threes．他们三三两两地来到了剧院。
D．表示人的不确切岁数或年代，用几十的复数形式表示。
He became a professor in his thirties．他三十多岁时成为了教授。
It was in the 1960s．那是在二十世纪六十年代。
F．基数词的句法功能
基数词在句中可作主语、宾语、定语、表语、同位语。
2. 序数词
表示顺序的词称为序数词。序数词的主要形式：
A．从第一至第十九 其中，one— first， two— second， three— third， five— fifth，eight—eighth，nine—ninth，twelve— twelfth为特殊形式，其它的序数词都是由其相对应的基数词后面添加“th”构成。例如： six— sixth、nineteen— nineteenth．
B．从第二十至第九十九
整数第几十的形式由其对应的基数词改变结尾字母y为i，再加“eth”构成。
twenty——twentieth thirty——thirtieth
C．第一百以上的多位序数词
由基数词的形式变结尾部分为序数词形式来表示。
one hundred and twenty-first 第一百二十一
one thousand，three hundred and twentieth 第一千三百二十
E．序数词的句法功能
序数词在句中可作主语、宾语、定语和表语。
注：序数词在使用时，通常前面要加定冠词 the；但是如果序数词前出现不定冠词a或an时，则表示“再——”，“又——”。
We've tried it three times．Must we try it a fourth time
我们已经试过三遍了，还必须试一次（第四次）吗？
另外，基数词也可以表示顺序。只需将基数词放在它所修饰的名词之后即可，不需要添加定冠词。
the first lesson——Lesson One
the fifth page——Page 5（five）
the twenty-first room——Room 21（twenty-one）
二、时刻表示法
三、加减乘除表示法
1. “加”用plus，and或add表示；“等于”用is，make，equal等词表示。
2. “减”用 minus或 take from表示
3. “乘”用time（动词）或multiply表示
4. “除”用divide的过去分词形式表示
四、分数表示法
1. 分数是由基数词和序数词一起来表示的。基数词作分子，序数词作分母，除了分子是“1”以外，其它情况下序数词都要用复数形式。
3/4 three fourths或 three quarters
2. 当分数后面接名词时，如果分数表示的值大于1，名词用复数；小于1，名词用单数。
五、百分数表示法
百分数用基数＋percent表示
50％ fifty percent 百分之五十
0.12％ zero point one two percent 百分之零点一二
这里的percent前半部per表示“每一”，cent这一后半部分表示“百”，所以百分之几中percent不用复数形式。
六、数量表示法
1. 表示长、宽、高、面积等，用基数词+单位词（meter，foot，inch，kilogram等）+ 形容词（long，wide，high等）表示，或者用基数词+单位词 + in + 名词（length， width， height， weight等）表示。
two meters long或 two meters in length 2米长
2. 表示时间、距离时，使用含数词的名词所有格形式作定语。
five minutes' walk
It's an hour's ride from my hometown to our university．
3. 由数词和其他名词构成的名词性短语作定语时，其中的名词用单数形式，名词性短语中各部分间要用连字符“-”来连接。
She's a sixteen-year-old girl．
4.表示倍数关系
a.“A + be + 倍数 + as + 计量形容词原级 + as + B”.
This tree is three times as tall as that one. 这棵树是那棵树的三倍高。
b.“A + be + 倍数 + 计量形容词比较级 + than + B ”
The dictionary is exactly five times more expensive than that one.
这本字典比那本恰好贵5倍。
c.“A + be + 倍数 + the + 计量名词 + of + B ”
The newly broadened square id four times the size of the previous one.
新扩建的广场是未扩建时的四倍大。
d.其它
