【正确答案】正确答案：Geographical variation can be generally divided into international variations and regional dialects. International variation refers to the variation of a language among different nations.(2 points)Regional dialects, on the other hand, denote the variations within one country. It refers to the variation of language correlating with the locality where the language is spoken. In other words, dialects are used by particular speech communities and associated with geographical settings or social groupings.(4 points) A speech variety which is appropriate to a limited social context is known as a register and it is used by a particular group of people, usually sharing the same occupation or the same interest.(2 points)A register must also include the expressions, the lexical-grammatical and phonological features, which accompany or realize these meanings; text can be seen as an instance of a register. A particular register can often distinguishes itself from other registers by having a number of distinctive words or by using words and expressions in a particular way.(4 points)

【答案解析】解析：考查方言和语域的定义及区别。语言的地域变体一般可以被划分为国际变异和地区方言。前者指一种语言在不同国家的变体，如美国英语和英国英语，后者指一个国家之内的语言变体，即具有当地特色的语言。一个国家不同地区的居民会讲母语的不同变体。语域是特殊人群使用的语言变体，是语言学中用来描述一种特定的语言风格和使用这种语言风格的语境之间关系的术语。某一语域通常有自己一些独特的词汇或使用词或短语的特殊方式。
