数词的用法总结

数词的用法总结

数词的用法总结
数词在英语中主要分为基数词和序数词两大类。

基数词用于表示数量的多少,如one,two,three等;而序数词则用于表示顺序,如first,second,third等。

数词在句中的用法相当于名词和形容词,可以作为主语、宾语、表语、定语、同位语等。

在使用数词时,有一些特殊的规则需要注意。

例如,当基数词hundred, thousand,million,billion等前面有具体的数字时,这些数词后面通常不加of;但如果泛指时,即使面有of,也必须使用单数形式。

此外,当分数表示法中分子大于1时,分母应使用复数形式。

在法律写作中,数字的使用需要遵守一定的规范,以确保其科学性、准确性和严谨性。

对于序数词的使用,需要注意的是,当序数词单独出现在句子中时,前面通常需要加上定冠词the;但如果序数词前有物主代词、名词所有格或其他修饰语,则不加冠词。

此外,序数词本身也可以用作名词,其后无其他名词时,可以直接使用。

语法-数词在英语中,表示数量多少和先后顺序的词被称为数词。

数词可分为两种:1.基数词表示"多少"的词叫做基数词,如:one (一),twenty(二十),hundred(百)等。

2.序数词表示"第几"的词叫做序数词,如:first (第一),twentieth (第二十),hundredth(第一百)等。

基数词用法相当于名词和形容词,可作主语,表语,定语,状语。

百/千a/one hundred/thousand 一万ten thousand 三万thirty thousand百万million 十亿billion a man in his forties 一个四十几岁的男人固定词组hundreds of 成百上千;好几百thousands of 成千上万;好几千tens of thousands of 好几万hundreds of thousands of 好几十万dozens of 好几打;好几十scores of 大量注意;当前面有数字时,不可以加s.e.g. Thousands of people c ame to see Jay Chow’s concert this evening.There are three thousand seats in this theatre.three dozen bottles of wine 36瓶酒They received dozens of letters from the readers.序数词说明:1)英语序数词1-19除第一(first),第二(second),第三(third)有特殊形式外,其余均由基数词后加-th 构成。

2)有几个序数词加-th 时拼法不规则,它们是:fifth,eighth,ninth,twelfth。

3)十位整数的序数词的构成方法是:先将十位整数基数词的词尾-ty 中的y变成i,然后加-eth.4)基数词"几十几"变成序数词时,仅将个位数变成序数词,十位数不变。

自考英语(一)英语语法基础材料:数词(1)

自考英语(一)英语语法基础材料:数词(1)数词的定义: 表示”多少”和”第几”的词,叫数词。

其用法相当于名词或者形容词。

数词分为基数词和序数词两种。

基数词: 表示数目的词是基数词,最基本的数词如下:1 one,2 two,3 three,4 four,5 five,6 six,7 seven,8 eight,9 nine, 10 ten, 11 eleven, 12 twelve, 13 thirteen, 14 fourteen, 15 fifteen, 16 sixteen, 17 seventeen, 18 eighteen, 19 nineteen, 20 twenty, 30 thirty, 40 forty, 50 fifty, 60 sixty, 70 seventy, 80 eighty, 90 ninety,100 a hundred, 1,000 a thousand,1,000,000 a million,1,000,000,000 a billion.基数词1-12 是独立单词,需逐个记忆。

基数词13 - 19是个位数词的词干后加-teen 构成。

其中thirteen, fifteen, eighteen, 变化不规则。

基数词20 ━90 是在十位数词后面加-ty 构成。

基数词21 ━99 是在十位数词后面加上个位数词合成,中间加上连字符“ ━“ 。

例如:21 twenty ━one 95 ninety ━five基数词三位以上的数词, 在百位和十位之间,一般要用连词”and “。

例如:132 one hundred and thirty ━two.1340 one thousand three hundred and forty表示”万”的词英语中没有.如1万可用10千来表示。

ten thousand. 30万可用three hundred thousand 来表示。

基数词的用法:从句子成分上分析,基数词在句中可用作主语,宾语, 表语等。

基数词在表示确切的数字时,不能使用dozen(12)、 score(20)、hundred、thousand、million 、billion 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。 two dozen eggs, three score of girls/three score days, six thousand… hundreds of , dozens of , thousands of, tens of thousands of, millions of…
16,250,064 sixteen million two hundred and fifty thousand sixty-four 5,237,166,234 five billion,two hundred and thirtyseven million,one hundred and sixty-six thousand, two hundred and thirty-four
小数表示法
小数用基数词来表示,以小数点为界,小数点左首的数
字为一个单位,表示整数,数字合起来读;小数点右首 的数字为一个单位,表示小数,数字分开来读;小数点 读作 point,o读作 zero或o,整数部分为零时,可以省 略不读. 0.4 zero point four或point four 零点四 10.23 ten point two three 十点二三 25.67 twenty-five point six seven 二十五点六七 l.03 one point o three 一点零三
分数的其它表达形式:
分子与分母之间加in, 分子在前,分母在后,分子分母都
用基数词。如:one in ten 十分之一,five in eight八分 之五。 分子与分母之间加out of , 分子在前,分母在后,分子分 母都用基数词。如:one out of ten十分之一,five out of eight八分之五
大约数的表示方法
(1)用ten、dozen、score、hundred、thousand、million等数词 的复数后加of短语来表示几十、几百、上千、成千上万等大约数 概念。 (2)用less than、under、below、almost、nearly、up to 等来表 示小于或接近某数目。 He is good at English, so he can finish the paper in less than two hours. (3)用more than、over、above、beyond、or more等来表示超过 或多于某个数目。如: Peking University has a history of more than 100 years. (4)用or、or so、about、around、some、more or less等表示在 某一数目左右。 About 50 people were present at that time. (5)用to、from … to…、between … and表示介于两数词。如: His salary rises from 20 dollars a week to 35 dollars a前加number,简写为No.。 如:No.1第一号 (2)事物名词的序号表达法有所不同: ①对于一些小序号可有序数词也可用基数词表达, 形式分别为:the + 序数词 + 名词;名词 + 基数词。 如:第一次世界大战可以表示为the First World War 或World War One, Lesson 8 =the eighth lesson ②对于一些大序号我们通常只用一种表达法,即名 词 + 数词。如:501号房间表示为Room 501, 538路公 共汽车表示为Bus 538。 ③可用a / the + number + 基数词 + 名词。如:a No.5 bus一辆五路公共汽车,the No.8 bus那辆8路 公共汽车。
序数词的句法功能
序数词在句中可作主语、宾语、定语和表语。
The second is what I really need. 第二个是我真正需要的。(作主语) He choose the second. 他挑选了第二个。(作宾语) We are to carry out the first plan. 我们将执行第一个计划。(作定语) She is the second in our class.在我们班她是第二名。 (作表语)
分数表示法
分数是由基数词和序数词一起来表示的。基数词作分子,序
数词作分母,除了分子是“1”以外,其它情况下序数词都要用 复数形式。 3/4 three fourths或 three quarters 1/3 one third或a third 24/25 twenty-four twenty-fifths 3 1/4 three and one fourth或 three and one quarter 1/2 a half 1/4 one quarter或a quarter 1 1/2 one and a half 百分数用基数+percent表示 50% fifty percent 3% three percent 分数和百分数后面不能直接接名词或代词,而用以下形式: 分数/百分数 +of + the /these/those/my+ 名词 / 代词, 其谓语 动词与of后的名词在人称和数上保持一致,如: Two-thirds of the money was spent on food. Seventy percent of the earth surface is covered by water. One third of the students are from the town.
基数词的句法功能
基数词在句中可作主语、宾语、定语、表语、同位 语。 The two happily opened the box.
两个人高兴地打开了盒子。(作主语) I need three altogether. 我总共需要三个。(作宾语) Four students are playing volleyball outside. 四个学生在外面打排球。(作定语) We are sixteen. 我们是16个人。(作表语) They three tried to finish the task before sunset. 他们三个人尽力想在日落前完成任务。(作同 位语)
序数词的主要形式:
A.从第一至第十九
one- first, two- second, threethird, five- fifth,eight-eighth,nine-ninth,twelve- twelfth 为特殊形式,其它的序数词都是由其相对应的基数词后面添 加“th”构成。例如: six- sixth、nineteen- nineteenth. B.从第二十至第九十九 整数第几十的形式由其对应的基数词改变结尾字母y为i,再加 “eth”构成。 twenty—twentieth thirty—thirtieth 表示第几十几时,用几十的基数词形式加上连字符“-”和个位 序数词形式一起表示 thirty-first 第三十一 fifty-sixth 第五十六 seventy-third 第七十三 ninety-ninth 第九十九
E.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。 2,648 two thousand six hundred and forty-eight
C.第一百以上的多位序数词 由基数词的形式变结尾部分为序数词形式来表示。 one hundredth第一百
one hundred and twenty-first 第一百二十一 one thousand,three hundred and twentieth 第一千三 百二十 D.序数词的缩写形式
序数词在使用时,通常前面要加定冠词 the;但是如果
序数词前出现不定冠词a或an时,则表示"再--","又--"。 We'll go over it a second time. We've tried it three times.Must we try it a fourth time? 表示日期用序数词 May 5 五月五日(读作May fifth),也可以表示为the fifth(5th)of May
倍数的表达方式
once, twice, three times, four times… (1)倍数用在as + 形容词 / 副词(原级)+ as结构之前。如: They have three times as many cows as we do.
