reduced doing vs reduced to do
- "reduced doing" 通常表示「減少做某事的頻率或程度」，強調行為本身的減少。
- "reduced to do" 則較為少見且不自然，通常不作為標準用法。正確的結構是 "reduced to + 名詞/動名詞"，表示「淪落到…的地步」或「被迫…」。
- 另一個常見結構是 "be reduced to doing"，表示「被迫或不得不做某事」，常帶有負面或無奈的意味。 EN: The company reduced spending on marketing after the budget cut. 翻譯: 預算削減後，公司減少了在行銷上的支出。
EN:After losing his job, he was reduced to taking any work he could find.
翻譯:失業後，他淪落到有什麼工作就做什麼的地步。

常見錯誤
What are common mistakes with "Reduced"?Which "Reduced" sentences look correct but are wrong?
×The price was reduced to half.
✓The price was reduced by half.
使用 'reduced by' 表示減少的幅度或數量，例如減少 50%、減少 10 元。使用 'reduced to' 表示減少後達到的具體數值或狀態。
×We need to reduce the cost.
✓We need to reduce costs.
當泛指成本、開支、浪費等概念時，通常使用複數形式 (costs, expenses, wastes)。使用單數形式 (the cost) 通常指特定一項已知的成本。
×He reduced smoking.
✓He reduced his smoking. / He cut down on smoking.
動詞 'reduce' 通常需要一個明確的受詞。'Smoking' 作為動名詞，前面常需要所有格代名詞 (his) 或量詞來使其成為明確的受詞。更自然的說法是使用 'cut down on' 這個片語。
×The noise reduced gradually.
✓The noise gradually reduced. / The noise was reduced gradually.
在英文中，副詞 'gradually' 等通常放在動詞前，或句首、句尾。原句語序不自然。此外，'reduce' 在此情境下常用被動語態，強調噪音被降低的過程。
×They reduced the budget for 10%.
✓They reduced the budget by 10%.
表示減少的百分比時，固定使用介系詞 'by'。使用 'for' 是錯誤的。
×This medicine will reduce your pain.
✓This medicine will relieve your pain. / This medicine will reduce your pain level.
雖然 'reduce pain' 在文法上正確，但在描述緩解疼痛時，'relieve pain' 或 'alleviate pain' 是更地道、更常見的搭配。若要使用 'reduce'，常會說 'reduce pain intensity' 或 'pain level' 使其更具體。
