一、Explain-the-fllowing-terms

1． basic level category

【答案】 Basic level category is the most economical level at which you can find the most relevant information. The information on our interactions with objects in the real world are stored at this level. It is at this level that we conjure up the general gestalt of the category.

2． Transformational-Generative grammar

【答案】 Transformational-generative grammar is proposed by Noam Chomsky. He postulated a syntactic base of language （called deep structure ） , which consists of a series of phrase-structure rewrite rules, i.e., a series of （possibly universal） rules that generates the underlying phrase-structure of a sentence. The end result of a transformational-generative grammar is a surface structure that is identical to an actual sentence of a language , after the mediating of a series of rules （called transformations ） that act upon the deep structures.

3． computational linguistics

【答案】 Computational linguistics is a branch of applied linguistics , dealing with computer processing of human language, h includes programmed instruction, speech synthesis and recognition, automatic translation, and computer mediated communication.

4． Slang :

【答案】 It refers to casual , very informal speech , using expressive but informal words and expressions.

For some people , slang is equivalent to colloquial speech but for others , it means “undesirable speech”. Usually , “colloquial speech” refers to a speech variety used in informal situations with colleagues , friends or relatives ，and “slang” is used for a very informal speech variety which often serves as an “in-group” language for a particular set of people such as teenagers , army recruits , pop-groups etc. Most slang is rather unstable as its words and expressions can change quite rapidly, for example , “Beat it!” “Scram!”，and “Rack off!” for “leave”.

5． Language acquisition

【答案】 It refers to the gradual development of ability in a language by using it naturally in communicative situations.

6． Embedding

【答案】 It refers to the inclusion of a clause within a phrase or another clause, or of a phrase into another phrase. An example of embedded clauses is: What I do is none of your business. （Nominal clause embedded as subject of another clause）

7． cohort model

【答案】 The cohort model is a supposed doctrine dealing with the spoken word recognition postulated by Marslen-Wilson and Welsh in 1990. It is suggested that the first few phonemes of a spoken word activate a set or cohort of word candidates that are consistent with the input. These candidates compete with one another for activation. As more acoustic input is analyzed , candidates that are no longer consistent with the input drop out of the set. This process continues until only one word candidate matches the input- the best fitting word may be chosen if no single candidate is a clear winner.

8． Categorization

Categorization is the process of classifying our experiences into different categories based 【答案】

on commonalities and differences. There are three levels in categories: the basic level，the superordinate level ，and the subordinate level.

9． Locutionary Act, Illocutinary Act and Perlocutionary Act

【答案】 According to Austin , a speaker might be performing three acts simultaneously when speaking.

A locutionary act is the uttering of words, phrases, and clauses, which conveys meaning by giving out meaningful sounds. Therefore, when somebody says „„Morning‟‟，we can ask a question like “What did he do?‟‟，and the answer could be “He offered a greeting.”

An illocutionary act is the act of expressing the speaker‟s intention; it is the act performed in saying something. Therefore, for the same example，we can say “He meant it as a greeting”.

A perlocutionary act is the effect of the utterance. Thus，by saying “Morning!” the speaker has made it clear that he wants to keep friendly relations with the hearer.

10．MT

【答案】 It refers to machine translation, the use of machine （usually computers） to translate texts from one natural language to another

二、Short-answer-questions

11．What are the four obvious barriers to adult L2 acquisition?

【答案】 A variety of explanations have been put forward for the apparent decline in adults:

Physical factors such as the loss of “plasticity” in the brain and “lateralization” of the brain; social factors such as the different situations and relationships that children encounter compared to adults ; cognitive factors such as the interference with natural language learning by the adulfs more abstract mode of thinking; and input factors that adults spend only a few hours each week of school time, rather than via the constant interaction experienced by a child, with a lot of other occupations.

12．Please explain the original idea in the speech act theory.

Motorist : My car needs new exhaust system.

Mechanic : I‟ll be busy with this other car all day.

【答案】 Speech act theory, originally proposed by Austin, is a philosophical explanation of the nature of linguistic communication.

Austin made a distinction between what he called “constatives” and “performatives”. Constatives were statements that either state or describe, and were thus verifiable; performatives, on the other hand, were sentences that did not state a fact or describe a state, and were not verifiable.

Later on, for a variety of reasons, Austin gave up his initial distinction between constatives and performatives. He set up another model to explain the way acts were performed by means of language. According to his new model, a speaker might be performing three acts simultaneously when speaking: locutionary act, illocutionary act, and perlocutionary act.

13．What is the definition of cognitive linguistics?

【答案】 Cognitive linguistics is a newly established approach to the study of language that emerged in the 1970s as a reaction against the dominant generative paradigm which pursues an autonomous view of language. Cognitive linguistics is based on human experiences of the world and the way they perceive and conceptualize the world.

14．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.

15．In English, the phonemeis pronounced differently in pat, spat, and tap, can you form a rule that can generalize this linguistic phenomenon?

【答案】 In English , there is a rule that a is unaspirated

after but aspirated in other places. So in pat , tap

is aspirated but unaspirated in spat since it is

after To bring out the phonetic difference , an aspirated sound is transcribed with a raised “h” after the symbol of the sound. So a

phonetic transcription for peak isand that for speak isSo are two different phones and are variants of the phonemeSuch variants of a phoneme are called allophones of the same phoneme. The allophones are said to be in complementary distribution because they never occur in the same context :

occurs after

while occurs in other places. We can present this rule as:

elsewhere

（note :

is the position in whichappears. ）

In addition, sometimes a phoneme may also have free variants. The final consonant of tap may not be released by some speakers so there is no audible sound at the end of this word. Such phenomenon is called free variation.
