7． distinctive features

a means of working out a set of phonological contrasts or oppositions to capture particular 【答案】

aspects of language sounds , first suggested by Roman Jacobson in the 1940s and then developed by numerous other people.

8． Denotation

【答案】 The core sense of a word or a phrase that relates it to phenomena in the real world. In the case of linguistic signs, the denotative meaning is what the dictionary attempts to provide. It is the literal meaning of a word, the dictionary meaning, opposite to connotation.

二、Short-answer-questions

11．What is the difference between mistakes and errors?

12．What are the three important points of the Prague School?

【答案】 The Prague School has three points of special importance , First , it stressed that the synchronic study of language is fully justified as it can draw on complete and controllable material for investigation. Second, it emphasised the systemic character of language, arguing that no element of any language can be satisfactorily analysed or evaluated if viewed in isolation. In other words, elements are held to be in functional contrast or opposition. Third , it looked on language as a tool performing a number of essential functions or tasks for the community using it.

13．What is the relationship between tree diagrams and structural ambiguity?

【答案】 In a theory of syntax using tree diagrams （phrase markers ） to represent syntactic structure , the explanation of the phenomenon of structural ambiguity is straightforward : whereas an unambiguous sentence is associated with just one basic tree diagram, a structurally ambiguous sentence is associated with more than one basic tree diagram.

14．What are the differences between voiced sounds and voiceless sounds in terms of articulation?

【答案】 When the vocal cords are spread apart , the air from the lungs passes between them unimpeded. Sounds produced in this way are described as voiceless, consonants [p, s, t] are produced in this way; but when the vocal cords are drawn together, the air from the lungs repeatedly pushes them apart as it passes through , creating a vibration effect. Sounds produced in this way are described as voiced [b, z, d] are voiced consonants.

15．Illustrate the relationship between morpheme and allomorph by examples.

【答案】 Morpheme is the smallest meaningful linguistic unit of language , not divisible or analyzable into smaller forms. What is usually considered a single word in English may be composed of one or more morphemes. Take disagreeable for example, it contains three morphemes, dis-, agree and -able. A morpheme may take various shapes or forms. For instance, -ion, -tion, -sion and -ation are the positional variants of the same suffix. They do not differ in meaning or function but show a slight difference in sound depending on the final phoneme of the preceding verb. They are called allomorphs. So an allomorph is any of the variant forms of a morpheme as conditioned by position or adjoining sounds.

16．How do you understand syntagmatic and paradigmatic relations?

【答案】 In Saussure‟s view, language is a system of signs, each of which consists of two parts: signified and signifier. And the relationships between these two parts are arbitrary. Syntagmatic relation is a relation between elements that form part of the same form , sequence , construction , etc. e.g. between s, p, and r in a form such as spring, or between a subject and a verb in constructions such as Bill hunts. The syntagmatic relation is also called horizontal relation or chain relation. Paradigmatic relation is a relation holding between elements replaceable with each other at a particular place in a structure. The paradigmatic relation is also called vertical relation or choice relation.

三、Essay-question

17．What are the unique features of Halliday’s systemic linguistics?

【答案】 Halliday‟s Systemic Grammar is different from other linguistic theories in the following aspects. First, it attaches great importance to the sociological aspects of language.

Secondly , it views language as a form of doing rather than a form of knowing. It distinguishes linguistic behavior potential from actual linguistic behavior.

Thirdly , it gives a relatively high priority to description of the characteristics of particular languages and particular varieties of languages.

Fourthly , it explains a number of aspects of language in terms of dines （i.e. ungrammatical —>more unusual —> less unusual—>less usual —> grammatical）.

Fifthly , it seeks verification of its hypotheses by means of observation from texts and by means of statistical techniques.

Lastly , it has as its central category the category of the system.

18．What are the major types of semantic Changes?

There are mainly three kinds of semantic changes, namely, broadening, narrowing, and 【答案】
