必备技能丨怎么用英语说'数字'？

小编英语课上给大家讲数字的时候，发现大家都对数字不怎么敏感。以前不理解为什么学生看着8能读成9，直到小编自己学了韩语才发现用一门陌生的语言说数字真的反应不过来！所以唯一的办法就是在弄清楚规则的前提下勤学苦练。今天给大家总结一下英语中数字的读法，拿出小本本做好笔记哦！

英语数字你能说对吗？你可能会觉得这很简单，不就是one two three four吗？

但是如果遇上大数字，你还知道该怎么说吗？比如……

全世界有70亿人口，你要说70 million, 7 thousand million, 70 billion还是7 billion？正确答案是最后一个，千万不要错把billion当成“亿”了。Million是百万的意思，而Billion则是十亿的意思。

其实，这都是因为老外记数字的说法和习惯和我们不太一样。他们常用的数字最高就是千，没有“万”的概念，正好和中文就差了一位数，3个零一组以“千”为单位进行区分。

这么说你也很难理解，就让老师来给你讲讲吧，你会明白为什么千位数上会有“小逗号”。

There are two main types of numbers:

Cardinal Numbers（基本数字） - 1 (one), 2 (two) etc. (Used mainly for counting)

Ordinal Numbers（序数） - 1st (first), 2nd (second) etc. (Used mainly for putting things in a sequence)

Cardinal Numbers

（基本数字）

Cardinal numbers are normally used when you:

1. count things: I have two brothers. There are thirty-one days in January.

2. give your age: I am thirty-three years old. My sister is twenty-seven years old.

3. give your telephone number: Our phone number is two-six-three, three-eight-four-seven. (481-2240)

4. give years: She was born in nineteen seventy-five (1975). America was discovered in fourteen ninety-two

Large Numbers（大数字）

100 - one hundred *

101 - one hundred and one

200 - two hundred

300 - three hundred

1,000 - one thousand

10,000 - ten thousand

100,000 - one hundred thousand

1,000,000 - one million

10,000,000 - ten million

100,000,000 - one hundred million

1,000,000,000 - one billion

* Instead of saying One Hundred, you can say A hundred.

e.g. (127) one hundred and twenty-seven OR (127) a hundred and twenty-seven.

The same rule applies for one thousand (a thousand) and one million (a million)

Notice that you need to use a hyphen (-) when you write the numbers between 21 and 99 (twenty-one, ninety-nine).

With long numbers, we usually divide them into groups of three which are divided by a comma.

e.g. 5000000 (5 million) is normally written as 5,000,000

Ordinal Numbers

（序数）

You can normally create Ordinal numbers by adding -TH to the end of a Cardinal Number.

Ordinal numbers are normally used when you:

1. give a date: My birthday is on the 27th of January. (Twenty-seventh of January)

2. put things in a sequence or order: Liverpool came second in the football league last year.

3. give the floor of a building: His office is on the tenth floor.

4. have birthdays: He had a huge party for his twenty-first birthday.

记住这些数字的英语说法，因为你不小心多说或少说一个零，那都是相当大的误差。就好比你们公司的销售额是900多亿，翻译成英语时如果不小心写成了“900 billion”，老外看到都要吓傻了……然后接下来怎么办呢？将错就错吗？

汉语和英语的大数计数习惯就差了一位数，但正是这一位数让多少人”阴沟里翻船“？

现在，你学会了吗？光听懂是不够的，要加强练习才行哦！
