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。

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:

負數英文數字
在數字前加上“negative”即可表示負數。
例子:

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 five
- 2023: 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 four
- 7.05: seven point zero five
- 負數 (Negative numbers): 數字前加上 “negative”
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 eleven
- 1280: One thousand two hundred and eighty
- 3001: 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 million
- 1,000,000,000: 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 → fiveth
- Eight → eighth
- Eleven → eleventh
- 數字以 -y 結尾 + -th, 轉為 -ieth 相應的序數
- Eighty → eightieth
- Twenty → twentieth
- Forty → fortieth
- 部分不規則變化的轉換序數例外情況
- One → first
- Two → second
- Three → third
- Four → forth
- Five → fifth
- Eight → eighth
- Nine → ninth
- Eleven → eleventh
- Twelve → twelfth
- Thirteen → thirteenth
