数词用法讲解及练习

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。

例如:twenty-one --- twenty-first, one hundred and one --- one hundred and first注意:序数词前常用定冠词,有时还可以用不定冠词a/an 则表示"又一"的意思。

例如:Mr Brown has a second car. 布朗先生另外还有一辆车。

初中英语数词用法及练习

初中英语数词用法及练习

初中英语数次归纳及练习数词主要分为基数词和序数词两类。

一、数词的分类1.基数词表示数目的词称为基数词。

其形式如下:A.从 1—— 10one,two, three, four ,five, six,seven, eight, nine,ten.B.从 11—— 19eleven,twelve, thirteen, fourteen, fifteen , sixteen, seventeen,eighteen,nineteen.这里除 eleven, twelve , thirteen, fifteen , eighteen 为特殊形式外, fourteen,sixteen,seventeen, nineteen 都是由其个位数形式后添加后缀 -teen 构成。

C.从 21—— 99整数几十中除 twenty,thirty, forty , fifty ,eighty 为特殊形式外, sixty, seventy,ninety 都是其个位数形式后添加后缀 -ty 构成。

表示几十几时,在几十和个位基数词形式之间添加连字符“-”21 twenty-one76 seventy-sixD.百位数个数基数词形式加“hundred,”表示几百,在几十几与百位间加上and.101 a hundred and one320 three hundred and twenty648 six hundred and forty-eightE.千位数以上从数字的右端向左端数起,每三位数加一个逗号“,”。

从右开始,第一个“,”前的数字后添加thousand,第二个“,”前面的数字后添加million ,第三个“,”前的数字后添加 billion 。

然后一节一节分别表示,两个逗号之间最大的数为百位数形式。

2,648 two thousand six hundred and forty-eight16,250,064 sixteen million two hundred and fifty thousand sixty-four5,237,166,234 five billion ,two hundred and thirty-seven million , one hundred and sixty-six thousand,two hundred and thirty-fourF.基数词在表示确切的数字时,不能使用百、千、百万、十亿的复数形式;但是,当基数词表示不确切数字,如成百、成千上万,三三两两时,基数词则以复数形式出现。

数词用法复习练习题及复习资料高考英语语法复习

数词用法复习练习题及复习资料高考英语语法复习

数词用法复习练习题与答案高考英语语法复习语法复习十六:数词高考重点要求:1.掌握基数词、序数词、分数词、倍数、百分数、年月日、钟点、年龄、序号的基本用法。

2.掌握不定数量词、约数词的表达方法。

数词在各个题项中,单选、阅读、听力、写作中发挥着很强的作用,往往用以说明事实的精确性和可信性。

数词是由两大部分构成的即基数词和序数词,而其他数字表示法如分数,小数等均由这两大部分的不同组合而构成。

数词分为基数词和序数词。

基数词表示人或事物的数量;序数词表示人或事物的先后顺序。

对于序数词的考查,单独出现的情况不多,有时放在阅读题中综合考察。

在学习过程中,要注意以下几个方面:1.基数词表示数量,序数词表示顺序;2.基数词与序数词之间的转换;3.数词与hundred, thousand, million等的连用。

数词数词考点大盘点数词在高考中虽然不像其它词类那么"热",但也有其考查的重点和难点,须引起同学们的注意。

一、考查基数词的用法1. 基数词hundred, thousand, million等表示确切数目时,其词尾不能加-s,其前面可用数词或several, some等修饰;当表示笼统数目时,其词尾要加-s,可跟of连用,其前不能用数词,但可以用several, some等修饰。

【原题再现】1. ________ people in the world are sending information by e-mail every day.A. Several millionB. Many millionsC. Several millionsD. Many million2. dozen和score的用法要注意以下几点:1) dozen与数词或many, several等连用时,不加-s,所修饰的名词前常省去of。

如two (many, several) dozen pencils。

但是,在a dozen of these / those people, two dozen of them等短语中应加of,这是习惯用法。

2) two score of people中应加of,但在three score and ten people(70人)中,不加of。

3) 表示"几十;许多"时,可使用dozens of; scores of形式。

【原题再现】2. Mr. Smith ________ me to buy several ________eggs for the dinner party.A. asked; dozenB. suggested; dozens ofC. had; dozenD. persuaded; dozens3. 注意年龄、年代的表达法。

▲掌握分数、时间、日期的表达法。

【复习要点】(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1 one 11 eleven 100 a hundred2 two 12 twelve 20 twenty 1000 a thousand3 three 13 thirteen 30 thirty 1,000,000 a million4 four 14 fourteen 40 forty 10,000,000 ten million5 five 15 fifteen 50 fifty 100,000,000 a hundred million6 six 16 sixteen 60 sixty 1,000,000,000 a billion7 seven 17 seventeen 70 seventy8 eight 18 eighteen 80 eighty9 nine 19 nineteen 90 ninety10 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。

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。
