常見錯誤
What are common mistakes with "Smooth"?Which "Smooth" sentences look correct but are wrong?
×He smoothed the paper.
✓He smoothed out the paper.
當表示「撫平、弄平」皺褶或不平整的表面時，通常使用 "smooth out" 這個片語動詞，而非單獨使用 "smooth"。
×We need to smooth the process.
✓We need to smooth the way / smooth the path for the process.
表示「使過程順利」時，常用 "smooth the way" 或 "smooth the path" 等慣用語。單獨使用 "smooth the process" 較不自然。
×He is smoothing his hair.
✓He is smoothing down his hair.
描述用手將頭髮「撫平、弄服貼」的動作時，通常使用 "smooth down"。
×The manager smoothed the conflict between the two departments.
✓The manager smoothed over the conflict between the two departments.

×Apply the cream to smooth your skin.
✓Apply the cream to smooth your skin. (This is acceptable) OR Apply the cream to make your skin smooth.
此處的錯誤在於語意不清。"smooth your skin" 可以指「撫摸皮膚」的動作，而非「使皮膚變光滑」。為避免歧義，在表示「使...變得光滑」時，常用 "make something smooth" 或語境清楚的被動式。
×The government took measures to smooth the economic transition.
✓The government took measures to smooth the economic transition. (This is correct)
此例句本身正確，常見的學習者錯誤在於將動詞 "smooth" 與形容詞 "smooth" 的用法混淆。需注意：動詞 "smooth" 後直接接名詞（如 transition, process）表示「使...順利」，是正確用法。錯誤在於誤以為這裡應該用形容詞形式。
