一、Explain-the-fllowing-terms

1． Language Acquisition Device （LAD ）

【答案】 Language Acquisition Device: LAD refers to an innate faculty of language in general with which children are bom. It is posited by Chomsky , who argues that LAD probably consists of three elements : a hypothesis-maker, linguistic universal, and an evaluation procedure.

2． 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.

3． Ferdinand de Saussure

【答案】 Ferdinand de Saussure is a Swiss linguist who is often described as “father of modem linguistics”. The great work , Course in General Linguistics , which was based on his lecture notes , marked the beginning of modem linguistics. Saussure^ idea on the arbitrary nature of sign , one the relational nature of linguistic units , on the distinction of langue and parole and of synchronic and diachronic linguistics, etc. pushed linguistics into a brand new stage.

4． 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.

5． Speech community

【答案】 Speech community is a group of people who share a set of norms and expectations regarding the use of language. Speech communities can be members of a profession with a specialized jargon , distinct social groups like high school students or hip-pop fans. In addition, online and other mediated communities, such as many internet forums, often constitute speech communities. Members of speech communities will often develop slang or jargon to serve the group's special purposes and priorities.

二、Short-answer-questions

6． How would you describe the oddness of the following sentences, using semantic features?

（a ）The television drank my water.

（b ）His dog writes poetry.

【答案】（a ） The verb drink represents a behavior of the animate beings, therefore, it is required that the subject of this verb should have a semantic feature as （+ANIMATE） , however, the word television , which is in position of subject, has an opposite feature:（-ANIMATE ） . That‟s why such a collocation results in oddness.

（b ） The action of writing poetry is normally one which only human beings could do, therefore, the subject is required to have a semantic feature as （+HUMAN） ; however, the word dog in the subject position is featured as （-HUMAN ） . Therefore, the sentence is odd.

7． What is free variation?

【答案】 Free variation is a linguistic term used both in phonology and sociolinguistics. In phonology , if two sounds occurring in the same environment do not contrast. For example ，the substitution of one for the other does not generate a new word but merely a different pronunciation of the same word, the two sounds are said to be in “free variation”.

For instance，both either and direction are pronounced differently in British English and American English without changing their meaning, which are often caused by the regional differences.

8． 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.

9． What does the concept morphophoneme mean? What is the relationship between phoneme and morphophoneme?

【答案】 Morphophoneme refers to the phoneme （or string of phonemes ） that constitutes the various allomorphs of a morpheme.

Relationship between phoneme and morphophoneme : Generally speaking , the concept of morphophoneme adds a grammatical meaning to the concept of phoneme. For example , as to the phoneme /s/, it is in fact a configuration of allomorphs of different morphemes , such as the plural morpheme and the 3rd person present simple morpheme. Therefore, we would regard this phoneme as a morphophoneme , represented as /s/.
