Expressing numbers in English can be confusing to both students and those listening. Make sure you understand how to express numbers in spoken English by following these rules.
用英語表達(dá)數(shù)字，無論是對(duì)學(xué)生還是聽者來說都是容易令人困惑的。通過遵循以下這些規(guī)則，可以確保你懂得如何用英語表達(dá)數(shù)字。

Below you will find numbers written out in order to helps students learn the correct grouping in English. Generally speaking, numbers larger than twenty should always be expressed by numbers in written English:
你會(huì)發(fā)現(xiàn)下面寫出的數(shù)字是為了幫助學(xué)生學(xué)習(xí)正確的分組。一般來說，大于二十的數(shù)在書面英語中應(yīng)該用數(shù)字表示：

I have fifteen clients in New York.
我在紐約有十五個(gè)客戶。

She has 240 contacts on her mailing list.
她的郵件列表上有240個(gè)聯(lián)系人。

Tens
十位數(shù)

Say individual numbers between one and twenty. After that, use the tens (twenty, thirty, etc.) followed by the numbers one through nine:
一到二十之間，我們讀單個(gè)的數(shù)字。二十往后，使用十位數(shù)（二十，三十等），緊接數(shù)字一到九：

7 - seven

19 - nineteen

32 - thirty-two

89 - eighty-nine

When expressing large numbers (more than one hundred) read in groups of hundreds. The order is as follows: billion, million, thousand, hundred. Notice that hundred, thousand, etc. is NOT followed by an "s"
當(dāng)表達(dá)大數(shù)字時(shí)（超過一百），以“百”為單位來讀。順序如下：十億，百萬，千，百。請(qǐng)注意，百、千等詞后面不加“s”

Two hundred NOT two hundreds
Two hundred不是two hundreds

Hundreds
百位數(shù)

Say numbers in the hundreds by beginning with numerals one through nine followed by "hundred". Finish by saying the last two digits:
讀百位數(shù)以一到九開始，緊接著“hundred”，以末尾的兩位數(shù)結(jié)束：

350 – three hundred fifty

425 – four hundred twenty-five

873 - eight hundred seventy-three

112 - one hundred twelve

NOTE: British English takes "and" following "hundred." American English omits "and:".
注：英式英語會(huì)在“hunderd”后加上“and”。美式英語則省略“and”。

Thousands
千位數(shù)

The next group is the thousands. Say a number up to 999 followed by "thousand." Finish by reading the hundreds when applicable:
下一組是千位數(shù)。先讀出999以內(nèi)的數(shù)字，后面緊接“thousand”，然后必要時(shí)，以百位數(shù)來結(jié)束。

15,560 – fifteen thousand five hundred sixty

786,450 – seven hundred six thousand four hundred fifty

342,713 - three hundred forty-two thousand seven hundred thirteen

569,045 - five hundred sixty-nine thousand forty-five

Millions
百萬位

For millions, say a number up to 999 followed by "million." Finish by saying first the thousands and then the hundreds when applicable:
對(duì)于百萬位的數(shù)，先讀出999以內(nèi)的數(shù)字，后面緊接“million”，然后必要時(shí)，先以千位數(shù)，再以百位數(shù)來結(jié)束。

2,450,000 – two million four hundred fifty thousand

27,805,234 - twenty seven million eight hundred five thousands two hundred thirty-four

934,700,000 – nine hundred thirty-four million seven hundred thousand

589,432,420 - five hundred eighty nine million four hundred thirty-two thousand four hundred twenty

For even larger numbers, first use billions and then trillions in a similar manner to millions:
對(duì)于更大的數(shù)字，先用十億位，再用萬億位，然后以相同的方式表達(dá)百萬位。

23,870,550,000 - twenty-three billion eight hundred seventy million five hundred fifty thousand

12,600,450,345,000 - twelve trillion six hundred billion four hundred fifty million three hundred forty-five thousand

Large numbers are often rounded to the next biggest or next smallest number to make things easier. For example, 345,987,650 is rounded to 350,000,000.
過于大量的末尾數(shù)往往被舍入到下一位最大或最小的整數(shù)，這樣就使讀數(shù)變得更容易。例如，345987650被舍入到350000000。

Decimals
小數(shù)

Speak decimals as the number followed by "point." Next, say each number beyond the point individually:
讀小數(shù)就讀出數(shù)字，緊接著加上“point”。然后后面的數(shù)字分別單獨(dú)來讀就行。

2.36 - two point three six

14.82 - fourteen point eight two

9.7841 -nine point seven eight four one

3.14159??? - three point one four one five nine

Percentages

Speak percentages as the number followed by "percent"
讀百分?jǐn)?shù)就讀出數(shù)字，緊接“percent”

37% - thirty-seven percent

12% - twelve percent

87% - eighty-seven percent

3% - three percent

Fractions

1/3, 2/3 - one third, two-thirds

1/2 - one-half

Read numbers together with fractions by first starting the number followed by "and" and then the fraction:
