一、Explain-the-fllowing-terms

1． Back-formation

【答案】 Back formation refers to an abnormal type of word formation where a shorter word is derived by deleting an imagined affix from a longer form already in the language. For example , the word “television” appeared before “televise”，and so does “editor” to “edit”.

2． CALL

【答案】 It is the abbreviation of computer-assisted language learning, which refers to the use of a computer in the teaching or learning of a second or foreign language. In this kind of CALL programs, the computer leads the student through a learning task step-by-step , asking question to check comprehension. Depending on the student^ response, the computer gives the student further practice or progresses to new material.

3． subordination

【答案】 Subordination refers to the process or result of linking linguistic units so that they have different syntactic status, one being dependent upon the other, and usually a constituent of the other. Thus the subordinate constituents are words which modify the Head. Consequently, they can be called modifiers. In the phrase swimming in the lake , swimming is the head and in the lake are the words modifying the head.

4． Textual function

【答案】 Textual function : The textual function is one of the three meta-functions language is composed of. It refers to the fact that language has mechanisms to make any stretch of spoken or written discourse into a coherent and unified text and make a living message different from a random list of sentences.

5． Allomorph

【答案】 A morpheme may take various shapes or forms, and an allomorph is any of the variant forms of a morpheme as conditioned by position or adjoining sounds. For instance, the morpheme of plurality {-s} has a number of allomorphs in different sound context, as in “cats” /s/, in “bags” /z/，in “matches” /iz/.

6． Diglossia

【答案】 When two languages or language varieties exist together in a community and each one is used for different purposes, this is called diglossia. Usually, the more standard variety can be called the high variety or H-variety , which is used in government , the media , education , and for religious services. The other one is usually a non-prestige variety, the low variety or L-variety used in the family, with friends, when shopping, etc.

7． phoneme

Phoneme is a basic unit of phonological study, and it is an abstract collection of phonetic 【答案】

features which can distinguish meaning. For example, in English, is described as a phoneme.

8． Applied linguistics

【答案】 It is a branch of linguistics which studies the application of linguistics in reality. For example , there are studies on multilingualism, language acquisition, first and second language teaching and learning.

二、Essay-question

9． What , in your view , makes a text a text , rather than a series of unconnected utterances? What are the implications of your answer for second language teaching?

【答案】 The factor to distinguish connected texts which make sense from those which do not is usually described as coherence. Coherence is traditionally described as the relationships that link the ideas in a text to create meaning for the readers, apart from cohesive devices. It should be noticed that cohesion by itself would not be sufficient to enable us to make sense of what read or hear; it is quite easy to create a highly cohesive text which has a lot of connections between the sentences, but which remains difficult to interpret. And coherence , as the invisible net of a text , performs a function of “connectedness” which makes the text interpretable to people.

Regarding the importance of coherence to a whole text, it seems necessary for a teacher of SFL to help students develop coherence in writing. Research has found that in their writing, ESL/EFL students focus almost exclusively on the word and sentence levels rather than the level of the whole discourse, that is , textual coherence. A pedagogical focus on coherence can shift students' attention from sentence-level grammar to discourse features such as textual structuring and propositional unity, which are crucial to creating meaning in texts. Indeed, helping students improve the coherence of their writing ought to be a significant aspect of L2 writing instruction.

To help students focus on coherence in writing , it is essential that teachers have a thorough understanding of what makes a text coherent. As is shown in the composition text books , it seems common to regard coherence simply as connectedness between sentences , use of explicit cohesive devices at the paragraph level, and use of connective devices such as pronouns, repetitive structures, and transitional markers. However , coherence should not be narrowed in terms of sentence-level connectedness and paragraph unity rather than discourse unity.

Thus , to help students create coherence in their writing, it is necessary for teachers to pay more attention in the broader sense of coherence.

10．MORPHEME is defined as the smallest unit in terms of relationship between expression and content. Then is morpheme a grammatical concept or a semantic one? What is its relation to phoneme? Can a morpheme and a phoneme form an organic whole?

【答案】 As a matter of fact, morpheme is both a grammatical concept and a semantic one. for instance , we can recognize that English word-forms such as talks , talker , talked and talking must consist of one element talk , and a number of other elements such as -s , -er , -ed , -ing. All these elements are described as morphemes. The definition of morpheme is “the smallest unit of language in terms of the relationship between expression and content”. We would say that the word reopened in the sentence The pglice reopened the investigation consists of three morphemes. One minimal unit of

meaning is open, another minimal unit of meaning is re- （meaning again） , and a minimal unit of grammatical function is -ed （indicating past tense） . Therefore, we are in a position to conclude that those which can stand by themselves as single words , e.g. open , are semantic concepts , and those which cannot normally stand alone, but which are typically attached to another form, e.g. re-, -ist, -ed, -s , are grammatical concepts.

As we know , each one of the meaning-distinguishing sounds in a language is described as a phoneme. An essential property of a phoneme is that it functions contrastively. If we substitute one sound for another in a word and there is a change of meaning, then the two sounds represent different phonemes.

The relation between morpheme and phoneme is also of two fold feature , viz. one-to-one , one-to-more. As with the former type, one-to-one, re- is the kind of morpheme that always consists of two phonemesas for the latter type, one-to-more relation, a typical example would be the plural morpheme that follows a noun or a

verb. after a noun can be pronounced in three ways ,

viz. and as in locks, bags, and watches; after a verb can also be pronounced in three ways,

viz. and as in stops, drags, and catches.

Seen from an integrative perspective, a morpheme and a phoneme, indeed, can form an organic whole , as the number of the sound of each morpheme cannot be unlimited.

11．Saussure puts forward the concept of langue and parole , and Chomsky puts forward the concept of competence and performance. Please dwell upon the differences and similarities, if any, of the two pairs: langue and parole vs. competence and performance.

【答案】 According to F. de Saussure, langue refers to the abstract linguistic system shared by all members of a speech community; while parole refers to the realization of langue in actual use.

For Chomsky, a fundamental distinction between linguistic competence and performance should be made. A language user‟s underlying knowledge about the system of rules is called linguistic competence. And performance refers to the actual use of language in concrete situations. In light with this , competence enables a speaker to produce and understand an indefinite number of sentences and to recognize grammatical mistakes and ambiguities. A speaker‟s competence is stable but his performance is often influenced by psychological and social factors, and thus would involve imperfections such as slips of tongue , false starts , unnecessary pauses , and so on. Thus , the point is that a speaker‟s performance does not always match his competence.

Saussure‟s distinction is somewhat similar with Chomsky‟s in the sense that they both refer to the constant factor which underlies the utterances that constitute parole/ performance. However , their difference is quite obvious. Saussue‟s language is a social product , a set of conventions for a speech community. Chomsky regards competence as a property of the mind of each individual. Saussrue looks at language more from a sociological point of view while Chomsky looks at it more from a psychological point of view.
