【正确答案】正确答案：The phenomenon described can be illustrated by the theory of cohesion and coherence in discourse analysis, especially the conjunctive kind of cohesive relation. Text processing requires inferences for establishing coherence between successive sentences. The achievement of coherence partly relies on the cohesive relationships within and between the sentences. Cohesion occurs where the interpretation of some elements in the discourse is dependent on that of another. It is realized partly through grammatical device and partly through lexical cohesion. Conjunction is one of the grammatically cohesive relations. It is based on the assumption that there are forms of systematic relationships between sentences in the linguistic system. Conjunction can be realized by some conjunctive words and some adverbs, such as so, but, furthermore, and so on. But in fact, the conjunctive relation between the discourses need not be realized by conjunctive words, as can be seen in these two examples. Yet it is not enough for the text to have connections between elements, there is also the coherence which distinguishes connected texts which make sense from those which do not. It enables people to make sense of what they read and hear, and then try to arrive at an interpretation which is in line with their experience of the way the world is. In fact, our ability to make sense of what we read is probably only a small part of that general ability we have to make sense of what we experience or perceive in the world. Therefore, by the coherence which helps us to connect the discourse with the world we experience, we the hearers will tend to make the discourse fit some situation which could accommodate all the details, and just as in the two examples, the causal conjunctive relations are established.
