“一对夫妇”的正常说法，是“a couple”，因为“couple”做名词，本身就是“夫妻/夫妇”的意思，就是指两个人。

加“a pair of”就属于“同义反复”，或者直白一点：“赘述”了。类似的还有“一支部队”，就是“an army”，而不是“a group of army/armies”。ouple = 一对，一双couples = 两对或以上夫妇有几个不同翻译， couple(s) 是其中之一比较精确的翻译是 married couple例：Tomorrow's dance is for couples only. You and Mary can go together as a couple.其他翻译有夫妻的英文；man and wife husband and wife情侣的英文是；lovers lovebirds couples我们是夫妻：We are husband and wife 例句：我们是夫妻，所以不能够分开。 We're husband and wife, we cannot be separated量词的其它用法:a pair of ｜ 一双a bunch of ｜ 一串a swarm of ｜ 一大群a herd of ｜ 一群（牛，羊）a pack of ｜ 一副，一包a flock of ｜ 一群a school of ｜ 一群a bouquet of ｜ 一束a class of ｜ 一类a team of ｜ 一队，一组
