一、Explain-the-fllowing-terms

1． 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.

2． 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.

3． Morpheme

【答案】 Morpheme is the smallest unit of language in terms of relationship between expression and content , a unit that cannot be divided into further smaller units without destroying or drastically altering the meaning , whether it is lexical or grammatical. For example , in boys , there are two morphemes : “boy” and “-s”； in international, there are three morphemes: “inter-” “nation” and “-al”.

4． 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.

5． Gradable antonym

【答案】 Gradable antonym. Gradable antonyms are antonyms that are gradable because there are often intermediate forms between the two members of a pair. For example, cold and warm constitute a pair of gradable antonyms.

6． 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 ）.

7． division of pragmatic labor

【答案】 Horn observes that the Q-based and R-based principles often directly collide and suggests the resolution comes from a division of pragmatic labor，which reads “The use of a marked （relatively complex and/or prolix） expression when a corresponding unmarked （simpler ，less “effortful”）alternate expression is available tends to be interpreted as conveying a marked message （one which the unmarked alternative would not or could not have conveyed） .

8． Surface structure

【答案】 It is a term used in generative grammar to refer to the final stage in the syntactic representation of a sentence, which provides the input to the phonological component of the grammar, and which thus most closely corresponds to the structure we articulate and hear. For instance, “John is easy to please.” and “John is eager to please.” are two sentences with the same surface structure.

二、Essay-question

9． Consider the following sentence, and then, answer questions （1） to （3） . The boy saw the man with the telescope.

（1）Is this sentence ambiguous? If so, describe the ambiguity briefly in your own words.

（2）Draw the constituent structure trees for each possible interpretation.

（3）What can be known about tree diagrams from （1） and （2） ?

Yes , this is an ambiguous sentence. This is a structurally ambiguous sentence, which 【答案】（1）

can be rewritten in two ways as follows:

a.The boy saw the man. The man had a telescope.

b.Using the telescope, the boy saw the man.

Since the sentence is an ambiguous one, which has two ways of interpretation, there are two （2）

ways of drawing constituent structure trees for it.

（3） Tree diagrams are more advantageous and informative than linear structure analysis. In addition to revealing a linear order, a constituent structure tree has a hierarchical structure that groups words into structural constituents and shows the syntactic category of each structural constituent, and consequently , can truthfully illustrate the constituent relationship among linguistic elements.

10．Explain one of the teaching approaches that you’re familiar with and discuss its advantages and disadvantages.

【答案】 The functional language teaching, which emerged during the 70s, is a reaction against both the structurally and situationally based approaches to language teaching. Its main feature is that we should teach people what functions the various linguistic forms fulfill. We should teach people not only what the language is but what the language does. Linguistic forms should not be presented as abstract structures but should always be presented as fulfilling a particular language function. For example, if the simple present tense is to be taught, it should not just be a matter of learning to accurately repeat the structure , but also a matter of knowing what the structure is actually used for.

Organizing language teaching functionally emphasizes what we can do with language. The basic units of language are seen as short exchanges. Linguistic forms are presented and learned in close relation to their function. Such teaching encourages appropriateness of language in terms of the respective roles of speaker and hearer and also in terms of the topic of conversation. Fluency is stressed and developed.

The teaching of language functions also presents problems. For example , what is exactly a language function? How many functions are there? In what order should they be taught?

While functions are a very significant aspect of language use, too great an emphasis on them may ignore other aspects of language, not least its structure. There is also no rigid correspondence between function and form, so some people object that we lose too much control over grammatical complexity if the syllabus is entirely organized on the basis of functions. What?s more, some argue that fluency and appropriate use of language may be encouraged but this should not be achieved at the cost of formal accuracy.

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 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
