英语数词用法归纳

一、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。

二、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。

三、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 / sixt eenth,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),th ree 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。

四、分数、倍数、小数和百分数

1.分数。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。

2.倍数。英语中表示倍数时通常借助half, double, twice, three times等之类的词。如:

They're twice the size of chickens. 它们比鸡大一倍。

Their house is about three times as big as ours. 他们的房子大约有我们房子三倍大。

3.百分数。百分数由基数词和百分号(%)组成,百分号(%)读作per cent。如:

thirty percent=30% 60 percent=60%

4、小数。小数点前的数按总数念,同其它基数词读法一样,小数点用point,小数点后面的数按基数词一个一个单独念。如9.65读作nine point six five。218.39读作two hundred and eighteen point three nine。

五、表示日期

1949年1949读作nineteen forty-nine

6月23日June 23rd读作June (the) twenty-third或the twenty-third of June

2006年10月October 2006 读作October, two thousand and six

1600年5月2日May 2nd, 2005读作the second of May, sixteen hundred

六、表示钟点

半小时用half,一刻钟用a quarter,半小时以内用past,超过半小时用to。

08:00 eight o’clock或eight

09:15 nine fifteen或a quarter past/after nine

02:30 two thirty或half past/after two

05:45 five forty-five或a quarter to six

五、表示约数

1. 用tens/dozens/scores/hundreds/thousands/millions of表示“几十、几百、上千、成千上万”等。如:

The boy bought dozens of pencils.那个男孩买了几十支铅笔。

Thousands of people died in the earthquake.数以千计的人死于地震。

2. 用less than, under, below, almost, nearly, up to等来表示小于或接近某数目。如nearly two hours将近两个小时。

3. 用more than, beyond, or more, over, above等来表示超过或多于某个数目。如more than 100 years一百多年。

4. 用or, or so, about, around, some, more or less等表示在某一数目左右。如about 50 pens大约五十支钢笔,

a month or so大约一个月。

5. 用to, from…to…, between…and表示介于两数词。如:

His salary rose from 100 dollars a month to 120 dollars a month.他的工资从每月100美元升到了每月120美元。_

英语数词地用法全归纳

英语数词的用法全归纳 数词的概述 英语中用来表示事物的数量或顺序的词叫做数词。根据数词的特征,可将数词分为基数词和序数词;根据数字是否为整数,有可将它分为整数、分数和小数;根据数字所表示的数是否确定,有可分为定数和概数。数词在句中可用作主语、表语、宾语、定语、同位语、状语等。 在表示基数词时,要特别注意hundred, thousand, million, billion等几个词的用法:若其前用了基数词,则不论其面是否有of,都必须用单数形式(此时若带of则通常表示特定范围中的一部分);若泛指数百、数千、数百万等,则用 hundreds of, thousands of, millions of 等这样的结构。 一、用英语表示生日的常用方法 有时简单地从汉语字面意思来看,看不出是用基数词还是序数词,此时不要想当然地乱用。如: 今天是我爷爷的60大寿。 误:Today is my grandfather’s sixty birthday. 正:Today is my grandfather’s sixtieth birthday. 汉语说“三十岁生日”“六十大寿”等,其实指的是过第30个生日,过第60个生日等,所以要用序数词而不用基数词。 二、用英语表示年龄的常用方法 (1)一般直接用基数词表示,如: Her daughter is eighteen. 她的女儿18岁。 (2)用“基数词 + years old”表示,有时可将years old 换成years of age。如: Her daughter is eighteen years old. / Her daughter is eighteen years of age. 她的女儿18岁。 (3)用“基数词-year-old”表示,此结构常做(前置)定语。如: Her 18-year-old daughter is now in the university. 他18岁的女儿现在上大学。 (4)用“at the age of +基数词”表示“在“在……年龄”。如: Her daughter got married at the age of eighteen. 她的女儿18岁就结了婚。 (5)用“of + 基数词”表示,此结构常做后置定语。如: Her daughter is now a pretty girl of 18. 她女儿现在一个18岁的美少女了。 (6) 用“aged +基数词”表示,此结构常做后置定语。如: Lying on the floor was a boy aged about seventeen. 躺在地板上的是一个约莫十七岁的男孩。 (7) 用“be in one’s +几十的复数形式”表示某人大概的年龄。如: He went to the United States in his fifties. 他五十多岁时去了美国。 三、用英语表示倍数的方法 表示倍数时通常借助half, double, twice, three times等之类的词: Half (of) the apples are bad. 一半苹果是坏的。
