小數的讀法

小數點的英文是「point」,先讀 point,再個別讀每個小數的數字。但金額並不是這樣的讀法。

0.5 point five
0.25 point two five

0.73

point seven three

0.05

point zero five

0.6529

point six five two nine

2.95

two point nine five

分數的讀法

分數的讀法,是先用基數來讀出分子,再用序數來讀出分母。如果分子大於一,序數則是複數。這種讀法可以用在所有分數上,但除了數字 2,當分母為 2 時,則讀作「half」;而如果其分子大於 1,分母則變成複數「halves」。

1/3 one third
3/4 three fourths
5/6 five sixths
1/2 one half
3/2 three halves

百分比的讀法

要用英語讀百分比很簡單,只要先唸數字在加上「percent」這個字即可。

寫法 讀法
5% five percent
25% twenty-five percent
36.25% thirty-six point two five percent
100% one hundred percent
400% four hundred percent

金額的讀法

若要用英語唸出金額,首先要先讀整個數字,再加上貨幣的名稱即可。但如果金額帶有小數,則在唸出整數部分後,再將小數點後的數字以整數方式唸出。如果幣制在貨幣單位上另有名稱,則在最後加上那個字。

寫法 讀法
25$ twenty-five dollars
52€ fifty-two euros
140₤ one hundred and forty pounds
$43.25 forty-three dollars and twenty-five cents(在日常口語上會縮減為「forty-three twenty-five」)
€12.66 twelve euros sixty-six
₤10.50 ten pounds fifty

測量單位的讀法

先唸出數字,再唸測量單位的名稱。通常測量單位在書寫上會用縮寫來表示。

寫法 讀法
60m sixty meters
25km/h twenty-five kilometers per hour
11ft eleven feet
2L two liters
3tbsp three tablespoons
1tsp one teaspoon

年份的讀法

英語中的年份讀法相當複雜。一般來說,當年份有四位數時,先將前面兩位數以整數方式來唸,後面兩位數則另外以整數方式來唸。但在這個規則有少數的例外;在西元兩千年的前一百年內,即使年份也帶有四個數字,但可以用整數方式來唸,或者以一般「兩位數兩位數」的方式來唸。西元一千年則一律以整數方式來唸,否則發音會拗口。西元世紀則以一百年為單位來唸。在兩千年以前的世紀,都不會用到 thousand 這個字。

有三位數的年份可以用一般數字的方式唸出,或者先唸第一個數字,再把後面兩個數字當整數來唸。而有二位數的年份則以整數來讀。為了要確切表達您的意思,可以在任何年份前面加 the year,這種方法對二位數和三位數的年份尤其常見。 而在西元前的年份則在數字後加 BC,讀音就如字母發音一樣。

有趣的是,這些規則也運用在地址中的數字上。

寫法 讀法
2014 twenty fourteen or two thousand fourteen
2008 two thousand eight
2000 two thousand
1944 nineteen forty-four
1908 nineteen o eight
1900 nineteen hundred
1600 sixteen hundred
1256 twelve fifty-six
1006 ten o six
866 eight hundred sixty-six or eight sixty-six
25 twenty-five
3000 BC three thousand BC
3250 BC thirty two fifty BC

0 的讀法

數字 0 在不同情況會有不同讀法。麻煩的是,同樣是英語系國家,但每個國家會有不同的使用情況。這些讀音運用於美式英語上。

讀音 使用的情況
zero 用來讀數字、讀小數、百分比、手機號碼以及某些固定用語上。
o (字母名稱) 用在讀年份、地址、時間以及溫度
nil 用在報導體育比賽分數
nought 在美國不使用
