常見錯誤
What are common mistakes with "Percentage"?Which "Percentage" sentences look correct but are wrong?
×A percentage of students are absent.
✓A percentage of students is absent.
當 "percentage" 前面有冠詞 "a" 時，動詞應使用單數形式，因為主詞是 "a percentage" 這個單數概念。
×The percentage of voters who support the policy are increasing.
✓The percentage of voters who support the policy is increasing.
當 "percentage" 前面有定冠詞 "the" 時，動詞也應使用單數形式，因為主詞是 "the percentage"。
×Twenty percentage of the population lives in rural areas.
✓Twenty percent of the population lives in rural areas.
在具體數字後面，應使用 "percent"（或符號 %），而不是 "percentage"。"Percentage" 是一個泛指的概念，不用於具體數字之後。
×A large percentage of the apples is rotten.
✓A large percentage of the apples are rotten.
雖然 "a percentage" 是單數，但當其後接 "of + 複數名詞" 時，動詞的單複數取決於說話者想強調的是整體比例（單數）還是群體中的個體（複數）。在大多數情況下，尤其是描述可數名詞時，動詞常用複數。此規則較為複雜，但學習者常誤用單數動詞。
×The percentage has increased.
✓The percentage of people using smartphones has increased.
"Percentage" 通常需要明確指出是「什麼的」百分比，即其後應接 "of + 名詞" 來使其語意完整。單獨使用 "the percentage" 會顯得語意不清。
×The survey shows interesting percentages.
✓The survey shows interesting data on percentages.
"Percentage" 作為「百分比」這個概念時是不可數的。雖然在數學上可以談論多個百分比數字，但在一般英文中，將其用作可數複數名詞（如 "percentages"）聽起來不自然。更自然的說法是 "percentage figures", "percentage points", 或像例句中那樣重組句子。
