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:

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
60 sixty 規則
70 seventy 規則
80 eighty 拼法更改(t不重覆)
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)

二十幾、三十幾[编辑]

在數字加個“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,

  • 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:

  • 1,900 = 口語:nineteen hundred 或正式:one thousand, nine hundred
    • 前者較常用
  • 1,600 = sixteen hundred 或 one thousand, six hundred
    • 前者較常用
  • 2,100 = twenty-one hundred 或 two thousand, one hundred
    • 後者稍微較常用
  • 3,700 = thirty-seven hundred 或 three thousand, seven hundred
    • 後者較常用

“hundred”之後要加個“and”才加十分數字(也可不加,见美式英语):

  • 1,903 = nineteen hundred and three 或 one thousand, nine hundred and three
  • 1,943 = nineteen hundred and forty-three 或 one thousand, nine hundred and forty-three

有另外一種快速口語說法:

  • Year 1903 = Nineteen-oh-three
    • 少於10的念“oh-#”,“oh”就是“0”(零)。但是不能說“zero-#”。
  • Year 1943 = Nineteen-forty-three
  • Year 913 = Nine-thirteen

有類似的說法,但是指的數目不一樣:

  • $ 19.03 = Nineteen-oh-three (類似1903年)

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:

  1. first(1st)
  2. second(2nd)
  3. 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”),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。
