“照惯例;按通常做法;像人们一向那样”。用于说明某件事是依照既定习惯或传统进行的(多见于较正式或叙述性文体)。也常见变体 as was the custom(“当时照惯例”)。
/æz ɪz ðə ˈkʌstəm/
As is the custom, we shook hands at the door.
照惯例,我们在门口握了手。
As is the custom in the village, guests are offered tea before any business is discussed.
按照村里的惯例,客人会先被奉茶,然后才谈正事。
短语由 as(“正如/像……一样”)+ is(系动词)+ the custom(“该习俗/惯例”)构成,直译为“正如(这)惯例所是”。其中 custom 来自中古英语 custome,源于古法语 costume/custum,再追溯到拉丁语 consuetudo(“习惯、常规”)。因此整句带有“按既定社会习惯行事”的书面叙述色彩。
