exchanged

基本解釋

14世紀(jì)晚期進(jìn)入英語(yǔ)，直接源自盎格魯法語(yǔ)的eschaunge；最初源自古典拉丁語(yǔ)的excambire：ex (出) + cambire (以物易物），意為互相交換。

exchange的基本意思是“交換”,可以表示以貿(mào)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(shí)還指在兩個(gè)或更多人之間換東西。引申可表示“交流”經(jīng)驗(yàn)、思想等。
exchange既可用作不及物動(dòng)詞,也可用作及物動(dòng)詞。用作及物動(dòng)詞時(shí),接名詞或代詞作賓語(yǔ),且所接的名詞一般為復(fù)數(shù)。
exchange賓語(yǔ)后常接介詞for,表示“以…換取”; 接介詞with表示“與某人交換(某物)”。
exchange后可接單數(shù)或是復(fù)數(shù)，一般在行動(dòng)上，會(huì)有單數(shù)形式出現(xiàn)。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(duì)換”，常用于give/get/receive后。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都不屬于正確用法。

There have been numerous exchanges of views between the two governments.
兩國(guó)政府間曾多次交換意見(jiàn)。
