英语/英文数字
英文數字和中文一樣都是十進數(decimal):有一到十十個形式(pattern),十一到二十形式重複,二十一到三十再重複。
基數(Cardinal numbers)
编辑一到十(One to ten)
编辑一到十都是單個音節(seven除外):
1 | one |
2 | two |
3 | three |
4 | four |
5 | five |
6 | six |
7 | seven |
8 | eight |
9 | nine |
10 | ten |
十幾(Teens)
编辑“十幾”(teens)原則在數字後加個“teen”,代表+10
例:
- 4 = four
- 14 = fourteen
- 6 = six
- 16 = sixteen(加了個“teen”,代表+10)
11 | eleven | 不規則 |
12 | twelve | 不規則 |
13 | thirteen | 拼法更改 thir |
14 | fourteen | 規則(没有缺u) |
15 | fifteen | 拼法更改 fif |
16 | sixteen | 規則 |
17 | seventeen | 規則 |
18 | eighteen | 拼法更改(t不重覆) |
19 | nineteen | 規則 |
幾十(Tens)
编辑20,30(tens)是在1-10基數詞後面加上“ty”(=×10)
20 | twenty | 拼法更改 twen |
30 | thirty | 拼法更改 thir |
40 | forty | 拼法更改 for(缺u) |
50 | fifty | 拼法更改 fif |

90 | ninety | 規則 |
不規則
编辑但是,11和12的不規則:
- 1 = one
- 11 = eleven
- 2 = two
- 12 = twelve
有些拼法有更改,要注意:
- 3 = three
- 13 = thirteen
- 30 = thirty
- 4 = four
- 40 = forty(沒有“u”)
- 但是fourteen(14)正常
- 8 = eight
- 18 = eighteen(一個t而已)
1 one |
11 eleven |
不規則 11 eleven | |

規則 |
二十幾、三十幾
编辑在數字前加個“twenty-”,代表+20(見#十幾(Teens))注意,一定要在twenty 和單數之間寫個連字號(-)。
例:
- 4 = four
- 24 = twenty-four
- 6 = six
- 26 = twenty-six
同樣的,在數字前加個“thirty”,代表+30(見#十幾(Teens))
例:
- 4 = four
- 34 = thirty-four(加了個“thirty”,代表+30)
- 6 = six
- 36 = thirty-six(加了個“thirty”,代表+30)
加個“forty”,代表+40,等等
大的數字
编辑一百多的數字前面寫個“one hundred and”
- “a hundred and”比較口語。
- 一定要寫“and”
例:
- 1 = one
- 101 = one hundred and one
- 31 = thirty-one
- 131 = one hundred and thirty-one
兩百多的數字前面寫個“two hundred and”。注意,
- 不需要複數形式:“two hundreds”←錯誤
- 例外:“There are five two hundreds in one thousand.”(在一千裡面有五個兩百。)←在此,“五個兩百”不是一個數字,所以有複數。關係是〔two hundred〕s,非two 〔hundred〕s。“two hundred”兩個字算一組,一起副數。
- 沒有連字號“two-hundred”←錯誤
其他:
- 千 = thousand
- 萬 = ten thousand(沒複數)
- 萬 = myriad
- 少用,大部分只表示“許多”的意思,例:a myriad of colours(許多顏色)
- 百萬 = million
- 連貫字:millionaire =百萬富翁
- 百萬以上的數字英國和美國名稱不一。下面举一个例子(美式读法):
- 16069380442589902755423214235476587698791962092 = sixteen quattuordecillion, sixty-nine tredecillion, three hundred and
eighty duodecillion, four hundred and forty-two undecillion, five hundred and eighty-nine decillion, nine hundred and two nonillion, seven hundred and fifty-five octillion, four hundred and twenty-three septillion, two hundred and fourteen sextillion, two hundred and thirty-five quintillion, four hundred and seventy-six quadrillion, five hundred and eighty-seven trillion, six hundred and ninety-eight billion, seven hundred and ninety-one million, nine hundred and sixty-two thousand, ninety-two
複雜數字
编辑英文寫數字,每三個字寫逗號:10,000,000,000
在每個寫逗號之地,拼字也寫逗號(非“and”)。
例:1,100 = one thousand, one hundred
Aside/較高級學習 |
---|
不過,通常口語說1,100像1100(分成兩個對):eleven hundred 再例:
“hundred”之後要加個“and”才加十分數字(也可不加,见美式英语):
算年有另外一種快速口語說法:
錢有類似的說法,但是指的數目不一樣:
五位數(10,000)就沒有如此口語了。 |
長的數字,一直往前建築,例:(以下綠字代表新的數字,注意標點符號)
- 5 = five
- 85 = eighty-five
- 485 = four hundred and eighty-five
- 3,485 = three thousand, four hundred and eighty-five
- 23,485 = twenty-three thousand, four hundred and eighty-five
- 923,485 = nine hundred and twenty-three thousand, four hundred and eighty-five
- 7,923,485 = seven million, nine hundred and twenty-three thousand, four hundred and eighty-five
- 87,923,485 = eighty-seven million, nine hundred and twenty-three thousand, four hundred and eighty-five
- 287,923,485 = two hundred and eighty-seven million, nine hundred and twenty-three thousand, four hundred and eighty-five
通常數學有小數點(decimal point)是成“point”,小數點之前的數字正常,之後一個一個數字念:
- 3,485.334531 = three thousand, four hundred and eighty-five point three-three-four-five-three-one
序數(Ordinal numbers)
编辑幾乎全部序數(ordinal number),“第…”,都是加個“th”(連在一寫),例:
- 六 = six
- 第六 = sixth
例外
编辑*“第一、二、三”完全改變:
- first(1st)
- second(2nd)
- third(3rd)
注意,是正常的“fourth”,不是“forth”。“forth”是另外一個字,意思“向前”。
*第五=fifth,非fiveth
*第八=eighth,非eightth
*第九=ninth,非nineth
* 第十二=twelfth,非twelveth
*所有“ty”結尾字(例:twenty、seventy、ninety)改為“tie”(發音不變:[tI])。加上“th”→“tieth”。
- 六十 = sixty
- 第六十 = sixtieth
- 但是,如果後面還有個數字(像“第六十九”),是“九”連接“th”結尾,非“六十”:sixty-ninth。
練習
编辑別忘了練習。數字沒練習是不會熟悉的。
