【正确答案】Linguistics is not the only field concerned with language. Other disciplines such as psychology, sociology, ethnography, the science of law and artificial intelligence etc. are also preoccupied with language. The interdisciplinary studies of language are also called macrolinguistics. They are sociolinguistics, anthropological linguistics, neurological linguistics, mathematical linguistics and computational linguistics.
1)Psych01inguistics
Psycholinguistics investigates the interrelation of language and mind, in processing and producing utterances and in language acquisition. As for English teaching, psycholinguistic focus on how a child acquires first and second language.
2)Sociolinguistics
Sociolinguistics is the study of the characteristics of language varieties, the characteristics of their functions, and the characteristics of their speakers as the three constantly interact and change within a speech community.
3)Anthropological linguistics
Anthropological linguistics is a branch of linguistics which studies the relationship between language and culture in a community, e.g. its traditions, beliefs, and family structure.
Language study and anthropology became closely associated in the early days of anthropological fieldwork when anthropologists enlisted the help of linguists to study unwritten languages.
4)Computational linguistics
Computational linguistics is an interdisciplinary field which centers around the use of computers to process or produce human language. Some current application areas include translating from one language to another (Machine Translation).

【答案解析】[解析] 本题考查宏观语言学的相关知识。语言学并不是与语言有关的唯一领域，另外一些学科，如心理语言学、社会学、人种学、法学和人工智能等，都与语言有关联。其中，①心理语言学研究语言和意识的相互关系，如话语的处理和产生，以及语言习得等。心理语言学还研究儿童语言的发展，如语言习得理论、语言的生物学基础及语言和认知的关系等。②社会语言学是一个很大的术语，它覆盖了大量有关语言和社会的问题，包括语言的社会功能和语言使用者的社会特征。社会语言学研究语言多样性的特征、它们的功能特征和说话者的特征以及这三者在言语社团中持续地交互作用和变化。③人类语言学家感兴趣的主要是早先无文字语言的历史和结构，他们关注语言的出现以及语言在千万年间的分化等。④计算机语言学是一个跨学科的领域，它以计算机处理和产生人类语言(即自然语言，与计算机语言相区别)这一应用为中心。
