常見錯誤
What are common mistakes with "Deduct"?Which "Deduct" sentences look correct but are wrong?
×They will deduct the tax from my salary.
✓They will deduct the tax from my salary.
雖然這個句子本身是正確的，但許多學習者會誤以為 'deduct' 和 'subtract' 在數學或日常計算中可以完全互換。實際上，'deduct' 通常用於從總額中扣除（如金錢、分數），帶有正式或商業意味；'subtract' 則是用於一般數學運算。
×The company deducted my salary because I was late.
✓The company deducted money from my salary because I was late.
錯誤句子的問題在於動賓搭配。'Deduct' 的受詞應是『被扣除的項目』（如 money, points, amount），而不是『被扣除的來源』（如 salary）。正確用法是 'deduct something FROM something'。
×I deducted the discount on the total price.
✓I deducted the discount from the total price.
這裡的錯誤是介系詞使用不當。'Deduct' 必須搭配 'from' 來指出從哪個總數或基礎中扣除，不能使用 'on'。
×My score was deducted by the teacher.
✓Points were deducted from my score by the teacher.
雖然語意上可以理解，但 'deduct' 較少用於被動語態來強調『分數被扣』。更自然的主動說法是『Someone deducts something from...』，或被動時將『被扣除的項目』（如 points, marks）作為主詞。原錯誤句將『score』作為主詞也不符合慣用邏輯。
×After deduct, the net amount is $80.
✓After the deduction, the net amount is $80.
'Deduct' 是動詞，不能直接放在介系詞 'after' 後面。這裡需要使用其名詞形式 'deduction'。這是詞性混淆的常見錯誤。
