数词的用法及训练

数词是表示数量多少或顺序先后的词。分为基数词和序数词。

(一)基数词

1. 表示数量多少的词是基数词,如:one, two, three等。

2. 数词的构成

1)从1-12分别由从one到twelve,12个各不相同的词表示。

one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve

2)从13-19均以后缀-teen结尾。

thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen

3)从20-90的整十数词均以后缀-ty结尾。表示“几十几”时,个位和十位之间需加连字符。

twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety

21 twenty-one 32 thirty-two 43 forty-three

4)整百数由1—9加hundred构成。

100 one (a) hundred 500 five hundred

5) 整百数和整十数之间由and连接,十位与个位之间要加连字符“-”。如果十位数为零,那就在百位和个位之间用and连接。

101 one hundred and two 245 two hundred and forty- five

6)千 thousand 百万 million 十亿 billion

2、序数词

序数词表示排列顺序,如first, second, third等。

构成规则:

1) 序数词第一、第二和第三为first, second和third,其他序数词的构成是在基数词后加th。例如:

six → sixth seven → seventh ten → tenth four → fourth

2) fifth(第五)、 eigth (第八)、 ninth (第九)和twelfth (第十二)在拼法上有变化。first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, tenth, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth

3) 二十、三十等基数词变为序数词时,要把y变成ie再加-th。例如:

twenty→twentieth forty→fortieth

twentieth, thirtieth, fortieth, fiftieth, sixtieth, seventieth, eightieth, ninetieth

4) 基数词几十几变成序数词时,表示几十的数词不变,只把表示几的基数词变成序数词。

例如:twenty-one → twenty-first forty-five → forty-fifth

5).序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。例如:

1st, 2nd, 3rd, 4th, 21st, 32nd, 40th

6) 序数词前必须加定冠词the

The first time I came to China, I liked it very much.

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

初中英语数词专项练习

数词 数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词;表示数目顺序的词叫序数词。 一. 基数词 1. 基数词就注意以下几点: (1)几十几的基数词的十位数与个位数之间要用连字符“-”连接。如: eighty-five 85 twenty-six 26 (2)三位数的基数词须在百位和十位(若无十位则和个位)之间用and连接。如: three hundred and sixty-five 365 two hundred and six 206 (3)基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或several修饰时,必须用单数。如: several hundred year’s ago几百年前 two thousand students两千个学生 2. 基数词的特殊用法: (1)表示“几十年代”或“几十岁”时,用逢十的基数词的复数形式。如: in the 1990’s 20世纪90年代 in o ne’s twenties在某人20多岁时 (2)用在习语中。如: in twos and threes三三两两地 二. 序数词 序数词应注意的几点事项: 1. 多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如: forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2. 当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。如: 21st第21 32nd第32 3. 序数词前一般要用定冠词the,如果序数词前用a或an时,则表示“又一;再一”(没有具体范围的限制)。如: Though he had failed twice, he wanted to try a third time. 尽管他已失败了两次,他还想再试一次。 The little monkey had had three apples, and he wanted to eat a fourth one. 那只小猴子已经吃了3个苹果,他还想再吃一个。 三. 分数和百分数 1. 分数 (1)分数的分子用基数词,分母用序数词。如: one fifth五分之一 one tenth十分之一 (2)当分子大于1时,分母用序数词的复数。如: two thirds三分之二 five eighths八分之五 (3)当分子是1时,可以用one也可以用a。如: a second = one second a third = one third (4)当分母是2和4时,分别可以用half和quarter代替。如:
