一、数词的概念:表示数量和顺序的词叫数词。

二、数词的分类:数词分为基数词和序数词。基数词表示数目。序数词表示顺序。

1

2

3. 序数词的构成:把基数词变为序数词时,请按下面的口诀记忆:

三、数词的基本用法:

a. 基数词的用法:

1. 表示房间、电话、门牌等的号码。

例如:电话号码:7521346: seven five two one three four six

102房间:Room One O Two 11路公共汽车:No. Eleven Bus

2. 表示年代、年龄、时刻等。

例如:1998年:nineteen ninety-eight(先读前两位,再读后两位)

2009年:two thousand and nine 12岁:twelve years old

8:00: eight/eight o’ciock 1:30: one thirty 2:40: two forty 3:45: three forty-five

★时间和日期的表达

有两种时间表达法:

A)直接读写数词。如:9:15 nine fifteen 10:30 ten thirty 11:45 eleven forty-five

7:05 seven o five 2:25 two twenty-five 5:55 five fifty-five

B)借助past和to来表达。past一般用于30分钟以内(含30分钟)的时间表达;to一般用于超过30分钟的时间表达。一刻钟可以用a quarter表示,半小时可以用half表示。

如:9:15 a quarter past nine 10:30 half past ten 11:45 a quarter to twelve

1. 表示顺序时用序数词,前面要加上定冠词the.

例如:January is the first month of a year.(一月是一年中的第一个月)

2. 表示日期时按月、日、年或日、月、年的顺序来表示,日子习惯上用序数词来表示。

例如:December 25th is Christmas Day.

★日期的表达:①月份+(the)+序数词如:November (the) 10th ②the+序数词+of+月份。如:the third of June六月三日

3. 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(名词需大写) 即可,不需要添加定冠词。

the first lesson—Lesson One ,the fifth page—Page 5,

the twenty-first room—Room 21

数词用法讲解及练习

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。
