英语/英文数字
英文数字和中文一样都是十进数(decimal):有一到十十个形式(pattern),十一到二十形式重复,二十一到三十再重复。
基数(Cardinal numbers)
[编辑]一到十(One to ten)
[编辑]一到十都是单个音节(seven除外):
1 | one |
2 | two |
3 | three |
4 | four |
5 | five |
6 | six |
7 | seven |
8 | eight |

[编辑]“十几”(teens)原则在数字后加个“teen”,代表+10
例:
- 4 = four
- 14 = fourteen
- 6 = six
- 16 = sixteen(加了个“teen”,代表+10)
11 | eleven | 不规则 |
12 | twelve | 不规则 |
13 | thirteen | 拼法更改 thir |
14 | fourteen | 规则(没有缺u) |
15 | fifteen | 拼法更改 fif |
16 | sixteen | 规则 |
17 | seventeen | 规则 |
18 | eighteen | 拼法更改(t不重复) |
19 | nineteen | 规则 |
几十(Tens)
[编辑]20,30(tens)是在1-10基数词后面加上“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 |

不规则
[编辑]但是,11和12的不规则:

- 2 = two
- 12 = twelve
有些拼法有更改,要注意:
- 3 = three
- 13 = thirteen
- 30 = thirty
- 4 = four
- 40 = forty(没有“u”)
- 但是fourteen(14)正常
- 8 = eight
- 18 = eighteen(一个t而已)
1 one |
11 eleven |
不规则 11 eleven | |
2 two |
12 twelve |

规则 |
二十几、三十几
[编辑]在数字前加个“twenty-”,代表+20(见#十几(Teens))注意,一定要在twenty 和单数之间写个连字号(-)。
例:
- 4 = four
- 24 = twenty-four
- 6 = six
- 26 = twenty-six
同样的,在数字前加个“thirty”,代表+30(见#十几(Teens))
例:
- 4 = four
- 34 = thirty-four(加了个“thirty”,代表+30)
- 6 = six
- 36 = thirty-six(加了个“thirty”,代表+30)
加个“forty”,代表+40,等等
大的数字
[编辑]一百多的数字前面写个“one hundred and”
- “a hundred and”比较口语。
- 一定要写“and”
例:
- 1 = one
- 101 = one hundred and one
- 31 = thirty-one
- 131 = one hundred and thirty-one
两百多的数字前面写个“two hundred and”。注意,
- 不需要复数形式:“two hundreds”←错误
- 例外:“There are five two hundreds in one thousand.”(在一千里面有五个两百。)←在此,“五个两百”不是一个数字,所以有复数。关系是〔two hundred〕s,非two 〔hundred〕s。“two hundred”两个字算一组,一起副数。
- 没有连字号“two-hundred”←错误
其他:
- 千 = thousand
- 万 = ten thousand(没复数)
- 万 = myriad
- 少用,大部分只表示“许多”的意思,例:a myriad of colours(许多颜色)
- 百万 = million
- 连贯字:millionaire =百万富翁
- 百万以上的数字英国和美国名称不一。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
复杂数字
[编辑]英文写数字,每三个字写逗号:10,000,000,000
在每个写逗号之地,拼字也写逗号(非“and”)。
例:1,100 = one thousand, one hundred
Aside/较高级学习 |
---|
不过,通常口语说1,100像1100(分成两个对):eleven hundred 再例:
“hundred”之后要加个“and”才加十分数字(也可不加,见美式英语):
算年有另外一种快速口语说法:
钱有类似的说法,但是指的数目不一样:
五位数(10,000)就没有如此口语了。 |
长的数字,一直往前建筑,例:(以下绿字代表新的数字,注意标点符号)
- 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
通常数学有小数点(decimal point)是成“point”,小数点之前的数字正常,之后一个一个数字念:
- 3,485.334531 = three thousand, four hundred and eighty-five point three-three-four-five-three-one
序数(Ordinal numbers)
[编辑]几乎全部序数(ordinal number),“第…”,都是加个“th”(连在一写),例:
- 六 = six
- 第六 = sixth
例外
[编辑]*“第一、二、三”完全改变:
- first(1st)
- second(2nd)
- third(3rd)
注意,是正常的“fourth”,不是“forth”。“forth”是另外一个字,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”结尾字(例:twenty、seventy、ninety)改为“tie”(发音不变:[tI])。加上“th”→“tieth”。
- 六十 = sixty
- 第六十 = sixtieth
- 但是,如果后面还有个数字(像“第六十九”),是“九”连接“th”结尾,非“六十”:sixty-ninth。
练习
[编辑]别忘了练习。数字没练习是不会熟悉的。
