I. INTRODUCTION1.1 What is linguistics?1.1.1DefinitionLinguistics is the scientific study of language. It studies not any particular language, but it studies languages in general.1.1.2 The scope of linguisticsGeneral linguistics: This deals with the basic concepts, theories, descriptions, models and methods applicable in any linguistic study, in contrast to those branches of study which relate linguistics to the research of other areas.Branches of linguistics:phonetics phonology morphology syntax semantics pragmatics Linguisticspsycholinguistics sociolinguistics applied linguistics1.1.3 Some important distinction in linguistics1) Prescriptive and descriptiveThey are two different types of linguistic study. If a linguistic study aims to describe and analyze the language people actually use, it is said to be descriptive; if the linguistic study aims to lay down rules for “ correct and standard” behavior in using language, i. e. to tell people what they should say and what they should not say, it is said to be prescriptive.Modern linguistics is mostly descriptive.2) Synchronic and diachronicLanguage exists in time and changes through time. The description of a language at some point of time in history is a synchronic study; the description of a language as it changes through time is a diachronic study. A diachronic study of language is historical study; it studies the historical development of language over a period of time.In modern linguistics, a synchronic approach seems to enjoy priority over a diachronic one.3) Speech and writingThey are the two major media of linguistic communication. Speech is prior to writingfor the following reasons:From the point of view of linguistic evolution, writing system os any language is always "invented" by its users to record speech when the need arises.Then in everyday communication, speech plays a greater role than writing in terms of the amount of information conveyedSpeech is always the way in which every native speaker acquires his mother tongue and writing is learned and taught later when he goes to school.4) Langue and paroleThe distinction between langue and parole was made by the Swiss linguist F. de Saussure in the early 20th century.Langue refers to the abstract linguistic system shared by all the members of a speech community, and parole refers to the realization of langue in actual use.Langue is the set of conventions and rules which language users all have to abide by, and parole is the concrete use of he conventions and the application of the rules. Langue is abstract; it is not the language people actually. Parole is concrete; it refers to the naturally occurring language events. Langue is relatively stable; it does not change frequently; while parole varies from person to person, and from situation to situation.5) Competence and performanceThe distinction between competence and performance was proposed by the American linguist N. Chomsky in the late 1950’s. Chomsky defines competence as the ideal user’s knowledge of the rules of his language, and performance the actual realization of this knowledge in linguistic communication.6) Traditional grammar and modern linguisticsThe beginning of modern linguistics was marked by the publication of F. de Saussure's book "Course in General Linguistics" in the early 20th century.a) Linguistics is descriptive, while traditional grammar is prescriptive.A linguistist is interested in what is said, not in what he thinks ought to be said. He describes language in all its aspects, but does not prescribe rules of "correctness".b) Modern linguistics regards the spoken language as primary, not the written. Traditional grammar tended to emphasize the importance of the written word.c) Modern linguistics does not force language into a Latin-based framework. However, for a long time traditional grammar assumed that Latin provides a universal framework into which all languages fit.1.2 What is language1.2.1 Definition of language?Language is a system of arbitrary vocal symbols used for human communication. First, language is a system, i.e., elements of language are combined according to rules.Second, language is arbitrary in the sense that there is no intrinsic connection between a linguistic symbol and what the symbol stands for.Third, language is vocal because the primary medium for all languages is sound.The term "human" in the definition is meant to specify that language is human-specific, i.e., it is very different from the communication systems other forms of life possess, such as bird songs and bee dances.2.2 Design featuresDesign features refer to the defining properties of human language that distinguish it from any animal system of communication. The framework was proposed by an American linguist, Charles Hockett.1) ArbitrarinessLanguage is arbitrary because there is no logical connection between meanings and sounds. However, we should be aware that while language is arbitrary by nature, it is not entire arbitrary; certain words are motivated.2) ProductivityLanguage is productive in that it makes possible the construction and interpretation of new signals by its users. This is the way they can produce and understand an indefinitely large number of sentences in our native languages, including sentences that we have never heard before.3) DualityLanguage is a system, which consists of two sets of structures, or two levels. At the lower or the basic level there is a structure of sounds, which are meaningless by themselves. But the sounds of language can be grouped and regrouped into a large number of units of meaning, which are found at the higher level of the system.Then the units at the higher level can be arranged and rearranged into an infinite number of sentences.4) DisplacementHuman language can be used to refer to things which are present or not present, real or imagined matters in the past, present, or future, or in far-away places. In other words, language can be used to refer to contexts removed from the immediate situations of the speaker.5) Cultural transmissionThe details of the linguistic system must be learned anew by each speaker. Though the capacity for language in human beings has a genetic basis, the particular language a human being learns is a cultural fact, not a genetic one.1.2.3 Functions of language1. Language is used for communication2. Three main functionsA)Descriptive function(cognitive, referential, or propositional function)--- it is assumed to be the primary function of language. It is the function to convey factual information, which can be asserted or denied, and in some cases even verified.B)Expressive function(emotive or attitudinal function) --- supplies information about the user's feelings, preferences, prejudices and values.C)Social function, also referred to as interpersonal function, serves to establish and maintain social relation between people.3.Function models by structural linguist Roman JakobsonHe identifies six elements of a speech event and relates each one of them to one specific language function.Addresser--- EmotiveThe addresser expresses his attitude to the topic or situation of communication. Addressee--- ConativeThe addresser aims to influence the addressee's course of action or ways of thinking. Context --- ReferentialThe addresser conveys a message or information.Message --- PoeticThe addresser uses language for the sole purpose of displaying the beauty of language itself.Contact --- Phatic communicationThe addresser tries to establish or maintain good interpersonal relationship with the addressee.Code --- MetalinguisticThe addresser uses language to make clear the meaning of language itself.4.Three macrofunctions by M. A. K. HallidayIn the early 1970s the British linguist Halliday found that child language performed seven basic functions and there is close correspondence language between form and function. But as a child grew into an adult the seven functions are gradually replaced by a more abstract, but also simpler system of functions. This system contains three macrofunctions.Ideational function is to organize the speaker or writer's experience of the real or imaginary world. It corresponds closely to the descriptive function discussed above, but it is broader because it also includes the expression of the speaker's attitude, evalution, his feelings and emotions.The interpersonal function is to indicate, establish, or maintain social relationships between people. It expresses the speaker's role in the speech situation, his personal commitment and assessment of the social relationship between the addressee and himself.The textual function is to organize written or spoken texts in such a manner that they are coherent within themselves and fit the particular situation in which they are used.。
