【正文】 c relation rather than the grammatical one and thus the position is rather flexible eg 如果雖然不但 etc 3 Another case for our attention is the correlative conjunctions They always occur in couplets joining various sentence elements that should be treated as grammatically equal such as bothand eitheror neithernor notonly whetheror 雖然但是因為所以如果那么不但而且即使也不論都 etc All of these correlative conjunctions should respectively be placed before phrases clauses or sentences they link The above forms usually occur in the formal style 23 Categories of text conjunctions The classification of a word is mainly determined by its semantic features grammatical features or formal features The judgment of grammatical features consists of the following 1 The ability to generate sentence We can see whether the word act as a ponent or not directly in the sentence and what role it plays 2 The power of bination We can see what kind of word it bines 3 The location it occurs We can see whether the place it occupies is before or after the subject Those floating conjunctions should be determined by their power of generating sentence and by the meaning they express There is no single uniquely correct inventory of the types of conjunctive relation each of which would highlight different aspects of the facts For example many scholars treat conjunctions as two principle types according to their functions in sentences coordinate conjunction and subordinate conjunctions The coordinate conjunctions connect words groups of words phases clauses etc that are independent of each other giving them a grammatical equality The monly used coordinate conjunctions are and or nor but yet as well as hence and so on In Chinese there are 和同與及以及而且或者 并而 and so on The conjunctions introducing the subordinate clauses are termed as subordinate conjunctions which are a large group including because if when since before after unless and many more In Chinese there are 因為如果假如假若若除非 etc A clause that begins with a coordinate conjunction must follow the clause to which it is linked but a clause that begins with a subordinate conjunction may generally follow it or precede it The clauses introduced by subordinate conjunctions are all restrictive Halliday and Hasan 197657 classify the discourse links as the following four types 1 Addictive the additive relation is a general semantic relation in the text forming ponent of the semantic system based on the logic notion of and This relation can be expressed by words and phrases such as and or furthermore similarly in addition whats more etc 2 Adversative the adversative relation is used to signal a meaning contrary to expectation It can be expressed by various words and phrases such as but however nevertheless though on the other hand etc 3 Causal the causal relation can be signaled by words and phrases such as so because therefore for this reason it follows from this etc 4 Temporal the temporal relation expresses the sequence of described events It is usually realized through words such as first next then after that an hour later when at last etc The classification by Halliday is very convenient for people to analyze and study conjunctions This paper is based on the four categories by Halliday 3 Function of conjunctions in English business letter Van Dijk 197987 proposed two functions of conjunctions semantic and pragmatic functions For him the semantic function of connectives is to relate facts whereas pragmatic function of connectives must be defined in terms of the structures and sequencing of illocutionary acts English business letter emphasizes the sequence of expression and the reasonable contents arrangement Conjunction may be a symbol of a new paragraph or a turning point of a meaning For example
