clearance 與 clearance to do
- clearance 作為名詞，通常指「許可、批准」的狀態或文件本身，後面不直接接動詞。
- clearance to do something 或 clearance for something 則是指「做某事的許可」或「針對某物的許可」，明確指出了許可的範圍或目的。
- 在正式或官方語境中，clearance to do 的結構更為常見，用以精確說明被授權的行動。
- 單獨使用 clearance 時，上下文或先前對話通常已暗示了許可的具體內容。 EN: The pilot received his security clearance. 翻譯: 飛行員獲得了他的安全許可。
EN:The pilot received clearance to fly the new aircraft.
翻譯:飛行員獲得了駕駛新飛機的許可。
EN:We are waiting for clearance from customs.
翻譯:我們正在等待海關的放行許可。
EN:We need clearance to export these goods.

常見錯誤

✓The plane got clearance from the tower.
在航空術語中，"clearance"（起飛或降落許可）通常是不可數名詞，前面不加冠詞 "a"。
×We need to do a clearance of the old stock.
✓We need to have a clearance sale of the old stock.
指「清倉大拍賣」時，應使用 "clearance sale" 這個固定搭配。單獨使用 "clearance" 無法準確表達此商業活動。

✓There is not enough clearance for the truck to pass underneath.
描述「從下方通過」時，介系詞通常使用 "underneath" 或 "under"，但 "pass under" 常指「在...下方行進」的狀態，而 "pass underneath" 更強調「從下方穿過」的動作，在此語境中更為精確。

✓Customs gave me clearance. / I cleared customs.
指「海關放行」時，"clearance" 通常是不可數的過程或狀態，而非一個可數的物件。更自然的說法是 "clear customs"（通過海關檢查）。"Customs" 作為機構名，常以大寫開頭且視為單數或複數名詞。
