常見錯誤
❗ 'The gearbox in my car is broken, so I need a new engine.' ✅ 'The gearbox in my car is broken, so I need a new gearbox.' — the gearbox and the engine are two separate parts; a gearbox problem does not mean the engine needs replacing.
❗ 'The mechanic changed the gearbox oil and the transmission fluid as two separate jobs.' ✅ 'The mechanic changed the gearbox oil as part of the transmission service.' — on most vehicles the gearbox is a major component inside the transmission system; they are not unrelated parts.
