一、Explain-the-fllowing-terms

1． 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/.

2． Innateness hypothesis

【答案】 The “Innateness Hypothesis” of child language acquisition was 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.

3． Achievement test

【答案】 Achievement test is a test which measures how much of a language someone has learned with reference to a particular course of study or program of instruction.

4． Corpus

【答案】 Corpus is a collection of linguistic data , either compiled as written texts or as a transcription of recorded speech. The main purpose of a corpus is to verify a hypothesis about language~~for example , to determine how the application of a particular sound , word , or syntactic construction varies.

5． 1-narrator

【答案】 The person who tells the story may also be a character in the fictional world of the story, relating the story after the event. In this ease the critics call the narrator a FIRST-PERSON NARRATOR or I- NARRATOR because when the narrator refers to himself or herself in the story the first person pronoun I is used. First-person narrators are often said to be “limited” because they don‟t know all the faces or “unreliable” because they trick the reader by withholding information or telling untruths. This often happens in murder and mystery stories.

6． The Innateness Hypothesis

【答案】 The innateness hypothesis was proposed by Chomsky. It says that the ability to acquire a human language is part of the biologically innate equipment of the human being, and that an infant is bom with this knowledge of basic grammatical relations and categories, and this knowledge is universal.

7． Stem

A stem is a morpheme or combination of morphemes to which an inflectional affix can be 【答案】

added. For example, “friend-” in friends, and “friendship-” in friendships are both stems. The former shows that a stem can be equivalent to a root, whereas the latter shows that a stem may contain a root and a derivational affix.

8． Cognition

【答案】 Cognition is, in psychology, used to refer to the mental processes of an individual, with particular relation to a concept which argues that the mind has internal mental states （such as beliefs, desires and intentions ） and can be understood as information processing , especially when much abstraction or concretization is involved , or processes such as involving knowledge , expertise or learning for example are at work. Another definition of “cognition” is the mental process or faculty of knowing , including aspects such as awareness, perception, reasoning, and judgment.

9． Lexical relations

【答案】 There are several types of lexical relations concerning the sense of the words. Those are synonymy , antonymy, hyponymy, polysemy, homonymy, and so on. （a ） Synonymy refers to the sameness relation ; “autum”, and “full ” are synonyms , for example , （b ） Antonymy refers to the oppositeness relation ; for example , “buy” and “sell ” are antonyms , （c ） Hyponymy refers to the inclusiveness relation; for example, “apple” is a hyponym of “fruit”, （d ） Polysemy means one word that has more than one related meaning ，and “bank”，as an example , is a polysemous word. （e ） Homonymy refers to the relation of two different words which are identical either in sound, or spelling, or both, such as “bow” （bau ） and “bow” （b əu ）.

10．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”.

二、Short-answer-questions

11．Is American English superior to African English? Why or why not?

【答案】 American English is not superior to African English. As different branches of English, African English and American English are equal. Similar as they are , they are influenced by their respective cultural context and thus form respective systems of pronunciation, words and even grammar.

12．What is the purpose of studying language and mind?

【答案】 The study of language and mind aims to model the workings of the mind in relation to language ; for example, it helps explain how the language production and perception is achieved. Since structures and connections in the mind are inevitably unobservable, researchers put forward hypotheses based on fragmentary clues. The label most usually given to the study of “language and mind” is psycholinguistics ，a term which is often perceived as being trendy. Psycholinguistics is concerned primarily with investigating the psychological reality of linguistic structures.

13．Whafs your understanding of language?

【答案】 Language is a system of vocal symbols used for human communication. Language must be a system, since elements in it are arranged according to certain rules, they cannot be combined at will. Language is arbitrary in the sense that there is no logic connection between the word and the thing it refers to. Language has symbolic nature : words are associated with objects , actions , ideas by convention. For all languages, the primary medium is sound, no matter how well developed are their writing system. Language is human-specific, it is very different from the communication system other forms of life possess.

14．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.

15．What is the relationship between linguistics and behaviorism according to Bloomfield?

【答案】 For Bloomfield, linguistics is a branch of the positivistic brand of psychology known as “behaviourism”. When the behaviourist methodology entered linguistics via Bloomfield, s writings, the popular practice in linguistic studies was to accept what a native speaker says in his language and to discard what he says about it. This is because of the belief that a linguistic description was reliable when based on observation of unstudied utterances by speakers; it was unreliable if the analyst had resorted to asking speakers questions such as “Can you say ... in your language?”

16．For the following words, state the conditions under which the different forms of the past tense appear. What determines
