compare: ruin ; destroy ; damage
①damage指部分“损坏”、“损害”、“破坏”或指使用价值有所降低。它可以用作动词,也可以用作名词,用作名词时常与to something 连用。
the accident did a lot of damage to his car.
②destroy 只能用作动词,指彻底破坏,以致不可能修复,常作“破坏”、“毁灭”解,也可以指希望、计划等打破。
the earthquake destroyed almost the whole town.
③ruin则表示破坏严重,以致不能修复,但这种破坏不像destroy那样毁灭某物,而是强调致使该物的使用价值发生了问题。用作动词时,它作 “使毁灭”、 “使崩溃”、 “弄糟”解;用作名词时,它表示 “毁灭”、 “瓦解”、 “废墟”等抽象概念。ruin也有借喻的用法。
