compact something vs compact something into something
- compact something 僅表示「壓實、壓緊某物」，強調動作本身。
- compact something into something 則強調壓實的結果，即「將某物壓實成（更小、更密的）某種形態或置入某個空間」。
- 當需要明確指出壓實後形成的特定形狀、體積或容器時，必須使用
into片語。 - 單獨使用
compact時，後果（如體積變小）是隱含的；使用into時，後果被明確表述出來。 EN: The machine compacts the trash quickly. 翻譯: 這台機器能快速壓實垃圾。
EN:The machine compacts the trash into dense bricks for recycling.
翻譯:這台機器將垃圾壓實成緊密的磚塊以供回收。

常見錯誤
What are common mistakes with "Compact"?Which "Compact" sentences look correct but are wrong?
×We need to make a compact of the trash.
✓We need to compact the trash.
將名詞 'compact'（契約、小粉盒）誤用為動詞。動詞 'compact' 意為『壓實、壓緊』，而非『製作契約』。
×We compacted the snow by our feet.
✓We compacted the snow with our feet.
表示使用工具或方法進行『壓實』動作時，應使用介系詞 'with'，而非 'by'。'by' 通常用於被動語態或表示方式，但此處指具體工具。
×The road is compacting well after the rain.
✓The road is compacted well after the rain.
此處想表達道路『被壓實』的狀態，應使用被動語態 'is compacted'（形容詞化的過去分詞）。'is compacting' 是現在進行式主動語態，意為『正在壓實』，主語通常是施動者。
×The roller can compact very efficiently.
✓The roller can compact soil very efficiently.
動詞 'compact' 是及物動詞，通常需要接賓語（受詞），說明壓實的是什麼東西。句子中缺少了被壓實的對象（如 soil, trash, material）。
×He compacted the can with his hand.
✓He crushed the can with his hand.
'Compact' 強調透過壓力使物質更緊密、結實，通常用於工程、垃圾處理等專業或正式場合。用手『捏扁』罐子更常用 'crush'。兩者雖有相關，但語意和常用情境不同。
