exchanged

基本解释

14世紀晚期進入英語，直接源自盎格魯法語的eschaunge；最初源自古典拉丁語的excambire：ex (出) + cambire (以物易物），意爲互相交換。

exchange的基本意思是“交換”,可以表示以貿易手段以一物換取另一物; 也可指一般的一物與另一物相交換; 有時還指在兩個或更多人之間換東西。引申可表示“交流”經騐、思想等。
exchange既可用作不及物動詞,也可用作及物動詞。用作及物動詞時,接名詞或代詞作賓語,且所接的名詞一般爲複數。
exchange賓語後常接介詞for,表示“以…換取”; 接介詞with表示“與某人交換(某物)”。
exchange後可接單數或是複數，一般在行動上，會有單數形式出現。They exchanged caps. 他們倆交換帽子。They exchanged a smile. 他們倆交換笑容。
exchange...with表示“和某人交換某物”，而exchange...for則表示“以某物換取某物”；
in exchange for表示“交換，對換”，常用於give/get/receive後。I should like to give my pen in exchange for yours. I should like to get/receive your pen in exchange for mine.
注意exchange本身包含交換的意思，避免和同類含義的詞搭配，如mutual exchange，exchange mutually，exchange with each other和exchange together都不屬於正確用法。
