①damage指部分“損壞”、“損害”、“破壞”或指使用價值有所降低。它可以用作動詞,也可以用作名詞,用作名詞時常與to something 連用。
the accident did a lot of damage to his car.
②destroy 只能用作動詞,指徹底破壞,以致不可能修復(fù),常作“破壞”、“毀滅”解,也可以指希望、計劃等打破。
the earthquake destroyed almost the whole town.
③ruin則表示破壞嚴(yán)重,以致不能修復(fù),但這種破壞不像destroy那樣毀滅某物,而是強(qiáng)調(diào)致使該物的使用價值發(fā)生了問題。用作動詞時,它作 “使毀滅”、 “使崩潰”、 “弄糟”解;用作名詞時,它表示 “毀滅”、 “瓦解”、 “廢墟”等抽象概念。ruin也有借喻的用法。
