数词
数词分为基数词和序数词两种，基数词表示人或事物的数量，序数词表示人或事物的次序。注：数词与不定代词、冠词、指示代词、形容词性物主代词等被称之为限定词。

基数词的构成和用法
（1）最基本的基数词如下表所示：
one two three four five six seven eight nine ten eleven
twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen
twenty thirty forty fifty sixty seventy eighty ninety
（2）基数词的写法
① 21～99 的两位数，十位与个位之间用连字符“－”。例：
◇ 21 twenty－one ◇ 32 thirty－two
◇ 98 ninety－eight ◇ 99 ninety－nine
② 101～999的三位数，百位数和后面的数之间用连词and，百、千等数词一律用单数形式。例：◇ 101 one hundred and one
◇ 225 two hundred and twenty five
◇ 999 nine hundred and ninety－nine
③ 1000以上的数，从后面向前数，每三位中间点“，”，第一个“，”前为thousand，第
二个“，”前为million，第三个“，”前为billion。例：
◇ 2，567 two thousand five hundred and sixty－seven
◇ 3，018 three thousand and eighteen
（3）基数词的用法
①作主语。例：
◇ Ten is a very important number．十是一个很重要的数字。
◇ Two and three are （is）five．2加3等于5。
②作定语。例：
◇ One kilometer is equal to two li．1公里等于2华里。
◇ She has three brothers．她有三个兄弟。
③作宾语。例：
◇ I wanted three but he gave me five．我想要三个，但他给了我五个。
◇ I get up before six every day．我每天六点之前起床。
④作表语。例：
◇—What time is it？几点钟啦？
—It’s ten．十点。
（4）疑难点
hundred，thousand和million在合成数词中一般用单数形式，但是用来表示不定数目时，用作复数形式。例：◇ Hundreds of workers will go on strike．
◇ Thousands of people are swimming in the river．
此时hundred，thousand等词前没有数词修饰，且通常其复数形式与of 连用。
序数词的构成与用法
（1）序数词的构成
①一般来说，是由相应的基数词加词尾th构成。例：
◇ four ＋th → fourth ◇ six ＋th → sixth
◇ seven ＋th → seventh ◇ ten ＋th → tenth
②下面这些基数词在变为序数词时，有特殊的变化。例：
◇ one → first ◇ two → second ◇three → third
◇ five → fifth ◇ eight → eighth ◇ nine → ninth
◇ twelve → twelfth
③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。例：
◇ twenty → twentieth ◇ thirty → thirtieth
◇ forty → fortieth ◇ ninety → ninetieth
④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。例：
◇ twenty－one → twenty－first
◇ thirty－five → thirty－fifth
◇ a hundred andfifty－three → a hundred and fifty－third
（2）序数词的用法
①序数词在使用时，一般加上定冠词。例：
◇ the first book ◇ the second floor
◇ the third day ◇ the fourth week．
②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。例：
◇ The may 1st is Labour Day．五月一日是劳动节。
◇ My room is on the second floor．我的房间在二楼。
◇ The first is larger than the second．（主语）第一个比第二个大。
◇ Read the book from the first．（宾语）从开头读这本书。
◇ You’ll be the sixth to write．（表语）你将是第六个写的。
③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。例：
◇ You may have a third try．你可以第三次尝试。
时间表示法
①时间都由基数词表示。例：
◇ It’s nine．现在九点。◇ It’s not five yet．还不到五点。
有时后面要加o’clock，但在口语中通常省略。
②几点几分表示法有两种形式。
A．倒读法：与汉语顺序不同，先读“分”后说“点”。30分钟以内，用“分钟数”＋past ＋“钟点数”表示“几点过几分”，超过30分钟，用“分钟数”＋to＋“下一个钟点数”表示“差几分到几点”。15分钟也可以用a quarter，30分钟也可以用a half。例：
◇ 2：15 a quarter past two ◇ 2：45 a quarter to three
◇ 1：55 five to two ◇ 7：05 five past seven
◇ 5：35 thirty five past five ◇ 9：30 half past nine
只有指几点钟整时才用o’clock，如ten o’clock，但不可以说seven past ten o’clock．
B．顺读法：与汉语顺序相同，连用两个基数词，第一个表示“点钟”，第二个表示“分钟”。
◇ 5：40 five forty ◇ 2：30 two thirty ◇ 1：15 one fifteen
这时的15和30不能用a quater, a half代替。
日期表示法
①年的读法：用基数词，分成两位一读。例：
◇ 1949 nineteen forty－nine ◇ 1840 eighteen forty
②月份的名称首字母要大写。例：
◇ January ◇ February ◇ March ◇ April
③日期用序数词表示，前面可加the，也可以省略。例：
◇ 5月4日May （the）fourth
◇ 10月1日October （the）first
④年、月、日的顺序：在英语中，按月、日、年的顺序来读。例：
◇ 1949年10月1日October （the）firstnineteen forty－nine
◇ 1999年5月1日May （the）first nineteenninety－nine
表示在“在某年、在某月”用介词in，如in2000，in September，表示“在某日”用介词on，如on July 8。
（5）编号的读法
①表示“第几课（部分，章或节）”时，用序数词时，前面一定要加冠词；用基数词时，不用冠词，但
语序与汉语相反。例：
◇ lesson one → the first lesson
◇ part three → the third part
②当数字较长时，通常用基数词。例：
◇第219页page 219 （two one nine）◇第306号房间room 306 （three o six）
◇第六路公共汽车bus number six
◇电话号码885316 telephone number 885316 （eight eight five three one six）
（6）分数、小数和百分数的表示法。
分数：分数分子用基数词，分母为序数词。分子为一时，分母为单，分子大于1，分母用复数。
One fourth 1/4 three fourths或three-fourths 3/4（连字符可用可不用）
小数：均用基数读出。0.02 zero point o two
百分数：用per cent/percent 表示。3% three percent
注：在带有分数的词组作句子的主语中，其后的谓语单复数形式要根据分数后面的名词的数决定。

It is not rare in _____ that people in ____ fifties are going to university for further education.
A. 90s, the
B. the 90s, /
C. 90s, their
D. the 90s, their
题解：表示“几十岁”；用in one’s + 数词复数，如：He began to work in his teens.
表示"年代"，用in +the +数词复数；
考题点击2
____ of the land in that district _____ covered with trees and grass.
A. Two fifth, is
B. Two fifth, are
C. Two fifths, is
D. Two fifths, are
题解：分数和百分数作主语时，关键是看其后的名词来决定其谓语动词的数。该题中的是不可数名词，所以动词需用单数。
提醒：表示百分之几或几分之几的人或物，记住一定要加of。如：百分之三十的学生，要说30% of the students.
巩固练习：将下列句子译成英文。
1.百分之四十的学生戴眼镜。
_________________________________________________________________
2.三分之二的钱花在食物上。
_________________________________________________________________

D. more than twice as many
题解：（倍数表示法）
主+谓+倍数(或分数)+ as + adj. (+ n.) + as I have three times as many as you.
三、倍数的表达方式
1. 主+谓+倍数+ as +形容词/副词（原级）+ as +比较对象。
This bridge is three times as long as that one . 这座桥是那座桥的三倍长。
2. 主+谓+倍数(分数)+ 形容词(副词)比较级+ than+比较对象

数词 （一）分类：数词有基数词和序数词两种。可以作句子的主语、宾语、表语和定语。 1、基数词：表示数目的词叫基数词。 常用的基数词有：
[注]：(1)百位与十位之间要加and；百位为0的话，就加在百位和个位之间。 108→one hundred and eight, 146→one hundred and forty-six, 500→five hundred , 1001→one thousand and one, 1813→one thousand eight hundred and thirteen. 一千：1000→one(a)thousand, 一万：10,000→ten thousand, 十万：100,000→one hundred thousand , 百万：1,000,000→one million, 千万：10,000,000→ten million, 亿：100,000,000→one hundred million, (2)英语用千、百万等单位计数，大数字从右向左看, 每隔三位划一逗号，倒数第一个逗号之前要用thousand，倒数第二个逗号之前要用million，倒数第三的逗号之前要用billion 表示。 3，456，789 three million four hundred and fifty- six thousand seven hundred and eighty-nine 6，004，001 six million four thousand and one (3) hundred、 thousand、 million表示确切的数时，不加s。如：five hundred(五百)，加S时表示不确定的数，后面必须要有of，前面可以加上some, many, several等词，翻译为：“成…上…”。hundreds of(成百上千的)，thousands of(成千上万的), millions of(成百万的) 2、序数词：表示顺序的数词叫序数词。 ①英语的序数词基本变法： (1) 一般在基数词后加th,(2)-ve结尾的改为-fth,(3)-ty结尾的改为-tieth,(4) 熟记特殊词。
数词 I.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。 II. 基数词 1. 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)。 2. 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。 3. 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。 III. 序数词 1. 许多序数词是由相应的基数词后加词尾-th构成的，如four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。 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 time. 我们得再做一次(from 。 序数词前用定冠词和不定冠词的区别在于：定冠词表特指，不定冠词表泛指，有类似another 的意思，但比another 的意思更明确。 IV. 分数、倍数、小数和百分数 1. 分数。 (1)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。

初中英语语法-数词及练习 一、内容概述 表示数目和顺序的词叫数词。数词可分为基数词和序数词两类 二、重点知识归纳及讲解 (一）基数词 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 twelve 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 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如81 eighty-one。4．101—999的基数词先写百位数，后加and再写十位数和个位数.如691 six hundred and ninety-one。 5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 7．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如：888，000，000读作：eight hundred and eighty-eight million。
