一、Explain-the-fllowing-terms

1． Polysemy

【答案】 Polysemy means a single word having several or many meanings. According to Crystal: Polysemy is a term used in semantic analysis to refer to a lexical item which has a range of different meanings. Polysemic words are signs of an advanced culture. Polysemy is also an essential feature of a language‟s economy and efficiency.

2． Presupposition

【答案】 A presupposition is a proposition （expressed in a sentence） that is assumed to be true in order to judge the truth or falsity of another sentence. For example , John didn't pass chemistry presupposes that John took chemistry.

3． Performatives

【答案】 Performatives are sentences that do not state a fact or describe a state. They cannot be said to be true or false. The uttering of these sentences is, or is part of, the doing an action. The judge‟s imprisonment sentence, the president‟s war or independence declaration, etc., are performatives.

4． CAI and CAL

【答案】 Computer-assisted instruction （CAI ） means the use of a computer in a teaching program. This includes:

a. A teaching program which is presented by a computer in a sequence. The student responds on the computer , and the computer indicates whether the responses are correct or incorrect.

b. The use of computers to monitor student progress, to direct students into appropriate lessons, material , etc. This is also called computer-managed instruction.

Parallel to CAI , there is CAL （Computer-Assistant Learning ） . The former aims at seeing educational problems on the part of the teacher, whereas the latter emphasizes the use of a computer in both teaching and learning in order to help the learner achieve educational objectives. The first kind of CAL programs which were developed reflected principles similar to programmed instruction. The computer leads the student through learning task step-by-step, asking questions to check comprehension. Depending on the studenfs response, the computer gives the student further practice or progresses to new material （see branching ）. In more recent CAL courseware students are able to interact with the computer and perform higher-level tasks while exploring a subject or problem.

5． Innateness hypothesis

【答案】 The “Innateness Hypothesis” of child language acquisition wa s proposed by Noam Chomsky , who states that language are somewhat innate and that children are bom with what he calls a language acquisition device, which is a unique kind of knowledge that fits them for language learning.

二、Short-answer-questions

6． What is the difference between meaning, concept, connotation, and denotation?

【答案】 Meaning refers to the association of language symbols with the real world. There are many types of meanings according to different approaches. Concept is the impression of objects in peopled mind ; connotation , meaning the properties of the entity a word denotes , is the implied meaning , similar to implication and implicature ; denotation , like sense , is not directly related to objects , but makes the abstract assumption of the real world. For example, the denotation of human is any person such as John and Mary, and its connotation is “biped‟‟ „„featherless‟‟ „„rational‟‟ etc.

7． Identify the type of trope employed in the following examples.

1）The boy was as cunning as a fox.

2）…the innocent sleep the death of each day‟s life, …（Shakespeare ）

3）Buckingham Palace has already been told the train may be axed when the rail network has been privatised. （Daily Mirror, 2 February 1993）

4）Ted Dexter confessed last night that England are in a right old spin as to how they can beat India this winter. （Daily Mirror, 2 February 1993）

【答案】 1） simile 2 ） metaphor 3 ） metonymy 4 ） synecdoche

8． Decide which maxim of the cooperative principle has been flouted in the following utterances and what implicature can be drawn.

（1）A : Can you tell me the secret?

B : But John is there.

（2）A : Let‟s go to the movies.

B : Fll bring the Kleenex.

（3）A : Would you drive a Mercedes?

B : I wouldn‟t drive ANY expensive car.

【答案】 In the exchanges, the maxim of relation has been flouted. As to instance （1） , A will assume that if B is cooperative his reply must be relevant in a different sense: I will not talk about my secret now because I do not want to let John know. In （2 ），the answer of B seems irrelevant to A‟s utterance. By doing so, A will likely derive the implicature that B has accepted his suggestion, and is going to get prepared. In （3） , by violating the maxim of relation , B intends to implicate that Mercedes is an expensive car and he would not drive a Mercedes.

9． 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.

三、Essay-question

10．Explain speech act theory and list the different kinds of speech acts with examples for each.

【答案】 The speech act theory was proposed by John Austin. According to this theory, we are performing various kinds of acts when we are speaking. Actions performed through utterances are generally called speech acts. An utterance can perform different speech acts depending on the context and that one speech act can be performed by more than one utterances.

According to Searle, speech acts all into five general categories. Specific acts that fall into each type share the same illocutionary point, but differ in their strength.

1）Representatives : the acts of saying what the speaker believes to be true; they include stating, describing , asserting, and so on; such as “It‟s raining”，“They won the game”.

2）Directives : acts of trying to get the hearer to do something. Commands , orders , requests , warnings , suggestions, and on so are of this type, as illustrated in “Be quiet!”，“Don‟t touch that!”

3）Commissives : acts of committing the speaker himself to some future course of action. They include promising，vowing , offering，threatening , and so on. Examples are “I‟ll take her to the vet.” and “We won‟t do that.”

4）Expressives : acts of expressing feelings or attitude towards an existing state. They can be statements of pleasure，pain ，likes ，sorrow , and so on. For example，“I‟m sorry to hear that”.

5）Declarations : acts of bringing about immediate changes by saying something. They include resigning , dismissing , naming, appointing, and so on. For example, the priest may say in a wedding “I now pronounce you husband and wife”.

11．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 eleme nts 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
