【正确答案】正确答案：If we want to know more about a given society or community by examining the linguistic behavior of its members, we are doing a sociolinguistic study of society. That is, we are doing sociolinguistics at a macro level of investigation. At this level of discussion, things that we are interested in include bilingualism or multilingualism, language attitudes, language choice, language maintenance and shift, language planning and standardization, vernacular language education, and so on. On the other hand, if we want to know more about some linguistic variations in language use by turning to potential socio-cultural factors for a description and explanation, we are doing a sociolinguistic study of language. Consequently, we are more interested in examining micro linguistic phenomena such as structural variants, address forms, gender differences, discourse analysis, Pidgin and Creole languages, and other more language related issues.
