數字英文說法與範例
0 – 20 英文數字
從 0 到 20 的數字都有獨立的單字形式，如下: Zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty。
21 – 99三位數 數字
從 21 到 99 的數字是由以下單字組合而成 twenty, thirty, forty, fifty, sixty, seventy, eighty, 或 ninety 再加上 1 到 9 的單位數字。
公式:
[十位數] + [個位數]
例如:
數字十位數 個位數完整寫法25TwentyFiveTwenty-five39ThirtyNineThirty-nine41FortyOneForty-one65SixtyFiveSixty-five73SeventyThreeSeventy-three99NinetyNineNinety-nine
練習英文詞彙發音
百位數的英文數字
百位數的讀法是將百位數字與 1 到 99 的數字結合。
公式:
[百位數] + hundred + (and + [十位數 + 個位數]) (若有後半部分)
注意: 只有當 “hundred” 後面還有十位或個位時，才使用 “and”。
例如:
數字英文讀法100One hundred101One hundred and one115One hundred and fifteen120One hundred and twenty134One hundred and thirty-four200Two hundred250Two hundred and fifty300Three hundred365Three hundred and sixty-five999Nine hundred and ninety-nine
千、百萬、十億的數字
數字英文讀法IPA音標1,000One thousand/wʌn ˈθaʊ.zənd/10,000Ten thousand/ten ˈθaʊ.zənd/100,000One hundred thousand/wʌn ˈhʌn.drəd ˈθaʊ.zənd/1,000,000One million/wʌn ˈmɪl.jən/1,000,000,000One billion/wʌn ˈbɪl.jən/1,000,000,000,000One trillion/wʌn ˈtrɪl.jən/
同樣地，對於非整數數字，在數字後加上對應百位、十位與個位:
數字英文讀法2,500Two thousand five hundred6,345Six thousand three hundred and forty-five3,200,000Three million two hundred thousand5,364,500Five million three hundred sixty-four thousand five hundred2,000,500,000Two billion five hundred thousand3,123,456,789Three billion one hundred twenty-three million four hundred fifty-six thousand seven hundred and eighty-nine
負數英文數字
在數字前加上“negative”即可表示負數。
例子:
–10: negative ten–3.5: negative three point five
英文數字使用方式
英文數字在英語溝通中是不可或缺的一部分。 若想正確使用英文數字，你需要掌握它們在以下情境中的用法：
使用情境 英文例句翻譯描述數量I have two cats.我有兩隻貓。She bought five books.她買了五本書。談論人或物的年齡He is twenty years old.他二十歲了。This tree is fifty years old.這棵樹已有五十年樹齡。讀電話號碼My phone number is 123-456-7890.我的電話號碼是123-456-7890。Call me at 098-765-4321.請打098-765-4321聯絡我.提及年份She was born in 1990.她出生於 1990 年。The event happened in 2023.這個事件發生於 2023 年。讀小數點The price is 3.75 dollars.價格是三點七五美元。Pi is approximately 3.14.圓周率約為三點一四。用於英文算術運算中Two plus three equals five.二加三等於五。Ten divided by two is five.十除以二等於五。
注意：英文中各種數學符號的名稱
符號英文名稱+plus–minus/subtract× hoặc *multiplied by/times÷ hoặc /divided by=equals/is
使用時需注意:
電話號碼: 每一位數字需單獨讀出。
例如: 098-765-4321 (zero nine eight, seven six five, four three two one)
年份:2000 年之前: 以兩位一組的方式讀出(例如: 1990: nineteen ninety)2000 年之後： 可讀2005: two thousand and five hoặc twenty oh five2023: two thousand twenty-three hoặc twenty twenty-three小數點數字: 使用 “point” 表示小數點，點後的每個數字都需單獨讀出。3.14: three point one four7.05: seven point zero five負數 (Negative numbers): 數字前加上 “negative”
此處持續更新折扣碼
使用英文數字的注意事項
數字中的重音
當你發音英文數字時，正確的重音位置可以幫助聽者更清楚理解，避免混淆:
結尾為 “-teen” 的數字(như thirteen, fourteen) 通常重音落在最後一個音節。
例如: Thirteen → /θɜːˈtiːn/
結尾為 “-ty” 的數字 (như thirty, forty) 通常重音落在第一個音節。
例如: Thirty → /ˈθɜːrti/
英式英語與美式英語在讀數方式上的差異
有兩種英語變體在讀數方式上存在一些細微差異：
數字 0:英式英語 常用 “nought” 或 “oh” (在電話中用)。美式英語 一般使用 “zero”。年份的讀法:英式英語 傾向於兩位一組讀: 2010 → twenty ten美式英語 可以讀: two thousand ten 或 twenty ten比較範例:101: one-oh-one (英式英語) 與 one-zero-one (Anh – 美式英語)2018: twenty eighteen (英式英語) 和 twenty eighteen 或c two thousand eighteen (美式英語)
數時 “and” 的說法
“and” 用來連接百位數／千位數與其後的數位部分:
111: One hundred and eleven1280: One thousand two hundred and eighty3001: Three thousand and one
確定數量時，數字後不加 “-s”
永遠不要直接在基數後加上 -s 來表示具體的數量。不過，在表示概數或大致數量時，可以加 -s，並搭配 “of” 使用:
詞組中文意思Tens of cars幾十輛汽車Dozens of eggs幾打雞蛋Hundreds of people數百人Thousands of trees數千棵樹Millions of fans數百萬名粉絲Billions of money數十億金錢
寫和讀數字時常見錯誤
忘記連字號: 從 21 到 99 的數字需要在十位與個位之間加上連字號。正確: twenty-one錯誤: twentyone混淆 “-teen” 和 “-ty”:16: Sixteen → /ˌsɪkˈstiːn/60: Sixty → /ˈsɪk.sti/
Note: 兩種數字的重音位置不同是區分它們的關鍵。
讀錯大數字: 閱讀大數時要清楚分辨每個數量級，以避免混淆 百萬 (million) 與 十億(billion).1,000,000: One million1,000,000,000: One billion

英文數字與序數的差異
區分英文數字與序數
數字 (Cardinal Numbers)序數 (Ordinal Numbers)功能用來表示事物或人的數量。用來表示順序、位置或等級。數字範例one (一), two (二), three (三), four (四)first (第一), second (第二), third (第三), fourth (第四)用法– 回答 “How many?” (多少?)– 用來計數，不表示順序。– 回答 “Which one?” (哪一個?) 或 “In what order?”– 用來表示位置或順序。例句– I have three apples. (我有三個蘋果。)– There are twenty students in the class. (班上有二十名學生。)– She finished in first place. (她得了第一名。)– Today is the second day of the trip. (今天是旅程的第二天。)
數字英文轉換成序數的規則
最簡單的方式將英文數字轉換為序數，就是根據末位數字加上 -st、-nd、-rd 或 -th，
但需注意一些不規則變化的情況，如 first、second、third 等。讓我們與 ELSA Speak 一起透過以下例子進一步了解吧！
加上 -th 在數字後 變為相應的序數Five → fivethEight → eighthEleven → eleventh數字以 -y 結尾 + -th, 轉為 -ieth 相應的序數Eighty → eightiethTwenty → twentiethForty → fortieth部分不規則變化的轉換序數例外情況One → first Two → secondThree → third Four → forthFive → fifth Eight → eighthNine → ninth Eleven → eleventhTwelve → twelfthThirteen → thirteenth
