数词
一、定义与分类
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。
二、基数词
1. hundred（百）, thousand（千）, million（百万）, billion(十亿)
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。
Unit 2 Numbers
There are in our school.
A. six hundred B. six hundred of (×) C. six hundreds (×)
D. six hundreds of (×) E. hundred (×) F. hundreds (×)
G. hundreds of (Tips: S, of 总相随，数字S冤家一队. )
2. 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。
one two three four five six seven eight nine
first second third fourth fifth sixth seventh eighth ninth
eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen
eleventh twelfth thirteenth fourteenth fifteenth sixteenth seventeenth eighteenth nineteenth
twenty thirty hundred thousand million
twentieth thirtieth hundredth thousandth millionth
三、序数词 ( hundred—hundredth thousand—thousandth million--millionth)
基数词表示几个，后接名词复数，而序数词表示第几个（即一个），后接可数名词的单数。
如：six friends(六个朋友) the sixth friend（第六个朋友）
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 time. 我们得再做一次。
四、分数、倍数、小数和百分数
1. 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。
2. 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：
They’re twice the size of chickens. 它们比鸡大一倍。
Their house is about three times as big as ours. 他们的房子大约有我们房子三倍大。
3. 百分数。百分数由基数词和百分号(%)组成，百分号(%)读作 percent。如：
thirty percent=30% 60 percent=60%
4、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。
五、表示日期
1949年1949读作nineteen forty-nine
6月23日June 23rd 读作June (the) twenty-third或the twenty-third of June
2006年10月October 2006 读作October, two thousand and six
1600年5月2日May 2nd, 2005 读作the second of May, sixteen hundred
六、表示钟点
半小时用half，一刻钟用a quarter，半小时以内用past，超过半小时用to。
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
七、表示约数
1. 用tens/dozens/scores/hundreds/thousands/millions of表示“几十、几百、上千、成千上万”等。如：
The boy bought dozens of pencils.那个男孩买了几十支铅笔。
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。
如: nearly two hours将近两个小时。
3. 用more than, beyond, or more, over, above等来表示超过或多于某个数目。
如: more than 100 years一百多年。
4. 用or, or so, about, around, some, more or less等表示在某一数目左右。
如: about 50 pens大约五十支钢笔，a month or so大约一个月。
5. 用to, from…to…, between…and表示介于两数词。如：
His salary rose from 100 dollars a month to 120 dollars a month.
他的工资从每月100美元升到了每月120美元。

A. good, bad 和far的比较级及最高级
学习good，bad和far 的比较级及最高级。这三个单词的比较级及最高级是特殊变化形式，没有规律可循，需要记忆。请看下表：

far farther / further farthest / furthest
注意：farther 和further 都是far 的比较级，两者的区别如下：
farther 指距离或时间上“更远的（地）”
further 指距离或时间上“更远的（地）”，可与farther互换
指程度上“更进一步；更深远”
例如：Guangzhou is farther / further from Beijing than Shanghai is.

其基本结构为as +形容词或副词原级+ as。
例如：This game is as interesting as that one. 这个游戏和那个一样有趣。
2.其否定式为not as / so +形容词或副词原级+as，意为“不如……”。
例如：This car is not as / so expensive as that one. 这辆轿车不如那辆贵。
