Like my major was linguistics, so I focused on English sociolinguistics and learned skills and knowledge that I could use in a future career.

比如我的专业是语言学，所以我的学习专注于英语社会语言学，学习相关的技能和知识，以便我在未来的职业生涯中使用。

The goal of sociolinguistics is to understand communicative competence— what people need to know to use the appropriate language for a given social setting.

社会语言学的目标是理解交际能力，即人们在特定的社会环境中使用合适的语言所需要的知识。
