demonstrated

demonstrated 是英語中的形容詞及動詞形式，英式與美式音標均為[ˈdemənstreɪtɪd]。作形容詞時意為"已證明的"，作動詞時為demonstrate的過去式與過去分詞，核心語義包括"證明事實""展示才能""表露情感""組織公眾遊行"等。該詞被柯林斯詞典收錄於CET4/TEM4級別詞庫，具有跨領域套用特徵，覆蓋學術論證、技術演示、社會運動等場景。

其詞義演變經歷功能擴展過程：早期側重邏輯證明，後衍生出才能展示、情感外顯等內涵。現代英語中既保留傳統學術論證用法（如科學實驗驗證），也新增民眾示威的社會性語義（如遊行抗議）。短語搭配涉及紀實能力、電路演示、良種示範等專業領域，反映其多語境適應能力。動詞變形規則完整，常見於雅思、托福等標準化考試，真題套用涵蓋技術操作示範、理論驗證、品質展現等場景。
