一、Explain-the-fllowing-terms

1． Minimal pairs

The two words which are identical in every way except for one sound segment that occurs 【答案】

in the same place in the string. For example，the English words bear and pear constitute a minimal pair as they differ in meaning and in their initial phonemes /b/ and /p/.

2． 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.

3． 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/.

4． Conceptualism

It is the view which holds that there is no direct link between a linguistic form and what it 【答案】

refers to; rather, in the interpretation of meaning they are linked through the mediation of concepts in the mind.

5． bound root

Bound root refers to the base form of a word that cannot further be analyzed without total 【答案】

loss of identity, and this base form could not occur alone, such as “-ceive” in “receive”.

6． Hyponymy

Hyponymy. It refers to the sense relationship between a more general, more inclusive and 【答案】

a more specific word. The word which is more general in meaning is called the superordiante, and the more specific words are called its hyponyms. For example , the hyponymy relationship could be established between “animal” and “rabbit”.

7． Bound morpheme

【答案】 Bound morphemes refer to those morphemes that can not occur alone and must appear with at least another morpheme. For example , in the word “careless”，“-less” is a bound morpheme since it could not occur by itself as a word.

8． Concord （or : Agreement）

【答案】 It may be defined as the requirement that the forms of two or more words of specific word classes that stand in specific syntactic relationship with one another shall also be characterized by the same paradigmatically marked category （or categories ） . For example, the syntactic relationship between that girl and she in the following dialogue: A: Who is that girl? B: Oh, she is my sister.

9． Concatenation

【答案】 What makes a word separate from other words is that all the letters are lined up together with no intervening spaces. That is, in a word, all letters are concatenated. Sometimes new words can be made by concatenating two existing words—for example, “airline” is a concatenation of the words “air” and “line” into a new word.

10．Glottal Stop

【答案】 V ocal tract is composed of oral cavity, nasal cavity and pharynx. When the vocal folds are totally closed, no air can pass between them. The result of this gesture is the glottal stop.

二、Short-answer-questions

11．Eskimos have many different words for different types of snow, Aborigines for different types of sand, and in Arabic one must choose from a whole range of words which are subsumed under the Western category CAMEL. Can you explain these phenomena with your linguistic knowledge?

【答案】 These phenomena can be explained from the following perspectives:

（1）These phenomena show a relationship between language and society. Language changes from region to region , from one social group to another and from individual to individual. The living environment makes great impact on the changes of language. As Eskimo are always living in an environment of a snow world, they have made a good cognition to snow and classified it in different types. Human use language to describe the world they have cognized.

（2）These phenomena can be explained from the Sapir-Whorf hypothesis. This hypothesis suggests that : our language helps mould our way of thinking and , consequently , different languages may probably express speaker‟s unique ways of understanding the world. So Eskimos^ different words for different types of snow reflect their different ways to understand snow.

12．What is the distinction between inflectional affixes and derivational affixes?

【答案】 The distinction between inflectional morphemes and derivational morphemes could be illustrated in the following four aspects.

Inflectional affixes very often only add a minute or delicate grammatical meaning to the stem, for instance , those inflectional affixes in words such as toys, walks, John's, etc. Therefore, they serve to produce different forms of a single word. In contrast , derivational affixes often change the lexical

meaning , e.g. cite, citation; generate, generation.

Inflectional affixes do not change the word class of the word they attach to，such as flower, flowers ; whereas derivational affixes might or might not, such as the relation between small and smallness for the former, and that between brother and brotherhood for the latter.

Very often inflectional affixes are conditioned by non-semantic linguistic factors outside the word they attach to but within the phrase or sentence. Whereas, derivational affixes are more often based on simple meaning distinctions.

In English, inflectional affixes are mostly suffixes, which are always word final. But derivational affixes can be prefixes or suffixes.

13．Why do people take duality as one of the important design features of human language? Can you tell us what language will be if it has no such design feature?

【答案】 Duality makes our language productive. A large number of different units can be formed out of a small number of elements——for instance, tens of thousands of words out of a small set of sounds. And out of the huge number of words, there can be astronomical number of possible sentences and phrases, which in turn can combine to form unlimited number of texts. Most animal communication systems do not have this design feature of human language.

If language had no such design feature , then it would be like animal communicational system which consists of only a number of basic sounds and this would be highly limited. Then we would not be able to produce a very large number of sound combinations （e.g. words ） , which are distinct in meaning. In other words, the number of messages one can send would be restricted to the number of basic sounds.

14．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.

15．How is language related to society?

【答案】 （1） While language is principally used to communicate meaning, it is also used to establish and maintain social relationships. This social function of language is embodied in the use of such utterances as “Good morning!”，“How is your family?' “Nice day today, isn‟t it?”

（2）Users of the same language in a sense all speak differently. The kind of language each of them chooses to use is in part determined by his social background. And language , in its turn , reveals information about its speaker.

（3）Language , especially the structure of its lexicon , reflects both the physical and social environment of a society. For example, while there is only one word in English for usnow, 9, there are several in Eskimo. This is a reflection of the need for the Eskimos to make distinctions between various kinds of snow in their snowy living environment.
