B. 用法总结
（一）基数词的表示方法：
基数词用来表示数目，或者说表示数量的词叫基数词。

最基本的基数词如下表所示。

1 one 11 eleven 100 a hundred
2 two 12 tw elve 20 twenty 1000 a thousand
3 three 13 thirteen 30 thirty 1，000，000 a million
4 four 14 fourteen 40 forty 10，000，000 ten million
5 five 15 fifteen 50 fifty 100，000，000 a hundred million
6 six 16 sixteen 60 sixty 1，000，000，000 a billion
7 seven 17 seventeen 70 seventy
8 eight 18 eighteen 80 eighty
9 nine 19 nineteen 90 ninety
10 ten
1. 1-12 的基数词：
one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve
2. 13～19的基数词，在个位数上加后缀 -teen构成，并有两个重音。

thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
3. 20～90等十位数由2-9 加后缀-ty构成。

twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
4. 21-29由十位数20加个位数1-9 构成，十位和个位之间加连字符号"－"，其他十位数以此类推。

21 twenty-one、44 forty-four、98 ninety-eight
5. 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)。

6. 用作基数词单位的 hundred, thousand, million, billion 通常不带复数词尾-s，
但若用于表示数百、数千、数百万这样的泛指，则用复数。

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。

7. 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(from )。

This took place in the 1930s. 这事发生在20世纪30年代。

8. 多位数的读法
①从后向前数，每三位数加一个"，"；第一个"，"号前为thousand（千），第二个
"，"号前为million（百万）……，然后再逐段表达。

②三位数数词要在百位和十位（若无十位则和个位）之间加and。

45，632，798 读作
forty-five million, six hundred and thirty-two thousand, seven hundred and ninety-eight
（二）序数词的表示方法：
第一到第十第十一到第十九第二十以上
first eleventh twentieth
second twelfth thirtieth
third thirteenth fortieth
fourth fourteenth fiftieth
fifth fifteenth sixti eth
sixth sixteenth seventieth
seventh seventeenth eightieth
eighth eighteenth ninetieth
ninth nineteenth hundredth
tenth thousandth
1.序数词 = 基数词+th，但以下几个特殊：
one-first, two-second, three-third, five-fifth. eight-eighth, nine-ninth, twelve-twelfth, twenty-twentieth ……, a hundred-a hundredth
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。

凡是以th结尾的序数词可缩写为“基数词+th”：4th, 5th, 9th, 11th, 60th, 128th等。

4.非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，thirty-sixth(第36)，ninety-ninth(第99)，three hundred and sixty-fifth(第365)等。

5.hundred, thousand, million 等序数词形式为hundredth, thousandth, millionth 等。

6.序数词前通常要用定冠词，但表示考试或比赛等的名次时，通常可省略其前的定冠词。

如：My room is on the second floor and his on the third. 我的房间在三楼，他的房间在四楼。

He was (the) third in the exam. 他考试得了第三名。

注：有时序数词前不用定冠词，而用不定冠词，表示次第在原有基础上的增加。

如：We’ll have to do it a second t ime. 我们得再做一次
（三）倍数、分数、小数、百分数的表示方法：
1. 倍数：英语中表示倍数时通常借助half, double, twice, three times等之类的词。

如：This room is three times as large as that one. 这个房间有那个房间三个大。

Three threes are nine. or Three times three is nine. 三三得九。

2. 分数：分数由基数词和序数词构成：分子用基数词，分母用序数词，当分子超过“1”时，分母用复数。

如：two thirds=2/3 three fifths=3/5 注：1/2 通常读作 a [one] half，一般不读作a second；1/4 可读作 a [one] fourth，也可读作 a [one] quarter。

数短语作主语时，谓语的数由of 后面的名词来决定，名词为可数名词复数，则谓语用复数；名词为不可数名词，谓语用单数。

A third of the land is covered by forests.
Two thirds of the workers are working hard.
3. 小数：小数点前的数按总数念，同其它基数词读法一样，小数点用point，小数点后面的数按基数词一个一个单独念。

如9.65读作nine point six five。

218.39读作two hundred and eighteen point three nine。

1.25 读作 one point two five
0.56 读作naught point five six或zero point five six

08:00 eight o’clock或eight
09:15 nine fifteen或a quarter past/after nine
02:30 two thirty或half past/after two
05:45 five forty-five或a quarter to six
（六）表示约数

如：

Thousands of people died in the earthquake.数以千计的人死于地震。

2.用less than, under, below, almost, nearly, up to等来表示小于或接近某数目。
