常見錯誤
What are common mistakes with "Deepen"?Which "Deepen" sentences look correct but are wrong?
×The government is trying to deepen the road.
✓The government is trying to widen the road.
"Deepen" 指的是增加深度或使某物更深，例如加深理解、加深關係或加深洞的深度。用於道路時，應使用 "widen"（拓寬）或 "repave"（重鋪），除非是在描述挖掘地下道。
×I need to deepen my English level.
✓I need to improve my English.
"Deepen" 不與 "level"（水平）搭配。描述語言能力的提升應使用 "improve"（改善）、"enhance"（增強）或 "advance"（進步）。"Deepen" 用於抽象概念，如知識、理解或關係。
×He deepened to study the problem.
✓He deepened his study of the problem.
"Deepen" 是及物動詞，後面通常直接接名詞作為受詞（如 deepen one's understanding），不能接不定詞 "to study"。應使用名詞形式或改寫句子。
×Their friendship was deepened after the trip.
✓Their friendship deepened after the trip.
"Deepen" 本身即可作為不及物動詞，表示「變得更加深厚」。在此語境下使用被動語態 "was deepened" 顯得多餘且不自然，主動語態更為簡潔常用。
×We must deepen to solve this crisis.
✓We must deepen our cooperation to solve this crisis.
"Deepen" 需要一個明確的受詞來指出加深的是什麼（例如合作、努力、對話）。不能單獨使用後接不定詞來表示目的，必須先說明加深的對象。
×Her voice deepened the room.
✓Her voice filled the room.
"Deepen" 不能用來描述聲音在空間中的傳播或充滿。描述聲音「低沉」用 "her voice deepened"（她的聲音變低沉了）。描述聲音「充滿房間」應用 "fill the room"。這是動詞與受詞搭配錯誤。
