数字表达

1.This box is two kilograms in weight.

这个盒子有两千克重。

推而广之,该句型可以应用很广泛,比如:

The tobacco plant grows from one to three meters in height.

烟草可以长到一至三米高。

2.The box is one point five meters wide and two meters high.

那个盒子是1.5米宽,2米高。

3.There are hundreds of people in the hall.

大厅里有数以百计的人。

同样地,表达成千上万可以这样说:

Thousands and thousands of people come to visit the Museum of Qin Terra-Cotta Warriors and Horses every day.

每天有成千上万的人来参观秦兵马俑博物馆。

4.He became a professor in his thirties.

他三十多岁时成为了教授。

在表示不确切岁数或年代时,可以用几十的复数形式表示,比如:

She died of lung cancer in forties.

她四十来岁时死于肺癌。

It was in the 1960s.

那是在二十世纪六十年代。

5.The second is what I really need.

我想要第二个。

用序数词表达自己的选择时,还可以这样说:

I will choose the second.

我会挑选第二个。

6.基数词+times+比较级+than……比……大(厚、高)几倍

This room is two times bigger than that one.

这个房间比那个(房间)大两倍。

The dictionary is four times thicker than that book.

这本词典比那本书厚四倍。

My age is two times older than his.

我的年龄比他大两倍。

7.2+3=? How much is two plus three?

“加”用plus,and或add表示;“等于”用is,make,equal等词表示。因此,2+3=5可以有如下表达方式:

Two plus three is five.

Two and three is equal to five.

Two and three make five.

Two added to three equals five.

If we add two to and three, we get five.

8.10-6=? How much is ten minus six?

“减”用minus或take from表示,10-6=4可以表达为:

Ten minus six is four.

Take six from ten and the remainder is four.

Six (taken) from ten is four.

9.3×4=? How much is three times four?

“乘”用time(动词)或multiply表示,3×4=12可以说:

Three times four is/are twelve.

Multiply three by four,we get twelve.

Three multiplied by four makes twelve.

10.16÷4=? How much is sixteen divided by four?

“除”用divide的过去分词形式表示,16÷4=4表示为:

Sixteen divided by four is four.

Sixteen divided by four equals/gives/makes four.

句型运用

B:It's not very big. It's a little over half a million square kilometers.

知识链接——英语中数字的表达方法

1.基数

词表示数目的词称为基数词。其形式如下:

从1—10:one, two, three, four, five, six, seven, eight, nine, ten.

从11—19:eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen.

除了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。

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“-”,比如:

21 twenty-one

76 seventy-six

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 one

320 three hundred and twenty

648 six hundred and forty-eight

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。比如:

2,648 two thousand six hundred and forty-eight

16,250,064 sixteen million two hundred and fifty thousand sixty-four

5,237,166,234 five billion,two hundred and thirty-seven million,one hundred and sixty-six thousand,two hundred and thirty-four

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。

2.序数词

表示顺序的词称为序数词。序数词的主要形式:

从第一至第十九,其中,第一——first,第二——second,第三——third,第五——fifth,第八——eighth,第九——ninth,第十二——twelfth为特殊形式,其他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.

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。如: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。比如:

thirty-first 第三十一

fifty-sixth 第五十六

seventy-third 第七十三

ninety-ninth 第九十九

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。比如:

one hundred and twenty-first 第一百二十一

one thousand,three hundred and twentieth 第一千三百二十

3.小数和分数:

小数点读作point,下面我们来看:

0.17 zero point one seven / point seventeen / zero point seventeen 零点一七

1/2 one half 二分之一

1/3 one /a third 三分之一

3/4 three fourths 四分之一

4.百分数

百分数用基数+percent表示:

50% fifty percent 百分之五十

3% three percent 百分之三

0.12% zero point one two percent 百分之零点一二

这里的percent前半部per表示“每一”,cent这一后半部分表示“百”,所以百分之几中percent不用复数形式。

5.数量表示法

表示长、宽、高、面积等,用基数词+单位词(meter,foot,inch,kilogram等)+形容词(long,wide,high等)表示,或者用基数词+单位词+ in +名词(length,width,height,weight等)表示。

two meters long 或 two meters in length 2米长

three feet high 或 three feet in height 3英尺高

four inches wide 或 four inches in width 4英寸宽 W/dHkH0R44lxCFQhEZnl4HPQojb8imvJTnTabaZjQ9KutRr9SUDIXP5WNT296/rJ
