社会群体 (group)分为内群体 (in -group)和外群体 (out-group)。内群体不可避免地对外群体产生成见并因此导致了对人们语言交际的影响。在言语交际中应避免民族中心主义 (ethnocentrism)、偏见 (prejudice)、歧视 (discrimination)和定势 (stereotypes) ,应提倡文化相对主义 (culturalrelativism)。 Social groups are divided into in-groups and out-groups. Inevitably, internal groups are prejudiced by external groups and thus have an impact on people’s language communication. Ethnocentrism, prejudice, discrimination and stereotypes should be avoided in verbal communication, and cultural relativism should be advocated.
