registers

registers
【正确答案】：Registers are language varieties appropriate for use in particular speech situations, in contrast to language varieties that are associated with the social or regional grouping of their customary users. For this reason, registers are also known as situational dialects. (P193)
【解析】与一种语言的习惯性言语使用者们的社会或地域群体的语言变体不同,语域是与一定交际情景相适应的语言变体。正鉴于此,语域又称为语言的情景变体。正式的场合要求正式的语域,而一个不正式的场合则可以用一种不太正式的语域来表达。
