學習英文中,倍數和小數的表達是我們常常碰到的挑戰。無論是在談論價格、描述數量變化,還是在數學運算中,掌握倍數和小數的表達技巧,能讓你用英文更加游刃有餘。今天,我們就來一場輕鬆的“數字冒險”,幫助你快速掌握這些實用的英文數字表達!
1. 倍數的神奇世界
讓我們先從倍數開始。當我們說某樣東西的數量比另一樣多幾倍,如何在英文中準確表達呢?
倍數的英文表達中,twice 和 three times 是最常見的兩個詞彙。這裡有一些倍數表達的規則:
- 兩倍:使用 “twice”。例如,”The price is twice as much as it was last year.”
- 三倍或更多倍數:使用 “times” 或 “fold”。如:“three times” 或 “threefold”。
常見倍數表格
倍數 | 英文表達 | 例句 |
---|---|---|
2 倍 | twice | The salary is twice what it used to be. |
3 倍 | three times / threefold | The population has grown three times over the decade. |
4 倍 | fourfold | The investment increased fourfold last year. |
10 倍 | ten times | Sales have risen ten times since the launch. |
如何靈活運用倍數?
倍數不僅僅是數字遊戲,還能在描述數據增長時給人留下深刻印象。比如,當你想要強調一個驚人的增長時,用 “fourfold” 這樣的詞彙來替代 “four times” 會顯得更加專業和震撼!
例子:
- “Our company’s revenue has increased threefold in the last year!”
聽起來是不是更加專業且引人注意呢?
2. 小數的精準運用
說完了倍數,接下來我們要進入到小數的領域。小數在日常生活中的用途可謂是無處不在,從購物到科學數據分析,它都扮演著重要角色。
英文中的小數點叫做 “decimal point”,當你看到數字如 1.5 或 3.141,這些都屬於小數表達。我們該如何正確地讀出這些數字呢?
- 1.5:讀作 “one point five”
- 3.141:讀作 “three point one four one”
這裡的重點是每個小數位都要單獨讀出,不像中文可以連讀。這樣的讀法在報告數據時尤其重要。
小數表達的表格對照
小數形式 | 英文讀法 | 例句 |
---|---|---|
0.25 | zero point two five | The distance is zero point two five kilometers. |
1.75 | one point seven five | The stock price increased to one point seven five dollars. |
2.01 | two point zero one | She ran two point zero one miles today. |
3.141 | three point one four one | The mathematical constant is approximately three point one four one. |
小數使用的實際情境
- 價格:”The cost of the item is one point five dollars.”
- 測量單位:”The length of the room is two point seven five meters.”
當你在國際場景下購物、談論投資或進行科學研究時,小數的準確表達能夠使你的對話更加專業。
3. 倍數與小數的應用場景
我們已經了解了如何讀出和表達倍數與小數,但如何在實際生活中應用它們呢?以下場景是你可能會用到的情境:
購物與價格:
- “This shirt is twice the price of that one.”
- “The discount is twenty-five percent, so the new price is seventy-five point zero dollars.”
投資與經濟:
- “Our profits have grown threefold in the last quarter!”
- “The inflation rate increased by zero point five percent.”
科學與測量:
- “The experiment showed an increase of two point five times in efficiency.”
- “The earth’s gravity is about nine point eight meters per second squared.”
通過熟悉這些倍數與小數的表達,你能在各種領域游刃有餘,無論是進行商務洽談、學術報告還是日常交流。

使用場景 | 小數或倍數 | 英文表達 |
---|---|---|
商品價格比較 | 2 倍 | The item is twice the price. |
折扣後的價格 | 小數 75.0 | The discounted price is seventy-five point zero dollars. |
體積增長 | 3 倍 | The volume increased threefold. |
科學數據 | 小數 1.25 | The measurement is one point two five liters. |
