The Study On The Mechanism And Pragmatics Strategies Of Sentence Fragment

Sentence fragment is the result of the conversation principle and the pragmatic tactics. The paper mainly focus on the Sentence fragment producing system ,The realization processing ,the adopting way and the influence on the language development ,which on the viewing of pragmatics and cognition .Sentence fragment is an uncompleted grammar alignment, which is produced in communication. The uncompleted expression is speakers'willing or we say the express it intentionally .In some special speaking situations, the Sentence fragment can make the harsh questions more mildly, which compare with the general question sentences; can avoid some unwilling topic; can make the listeners not feel so embarrassed, which cannot make their answers so limited. Sometimes, the speakers will control to express themselves, they will give hints to the listeners, by this way, they can try to know the listeners, intention or they can use the listeners'expression to realize their intentions, and by nature, they can own the positive situation. And some of the Sentence fragments produced by the in-timed resurrecting in communication, as usual, will choose a topic which pretty related to the former one to make it more mildly, also it can satisfy the listeners or we say it can not make the listeners feel embarrassed, so that can make the communication smoothly.It is obvious that the existing of Sentence fragment disobey the quantity principles and method principles which belong to the cooperation principles,; according to the theory, it is unfavorable to the listeners to understand and adopt. At the matter of fact, in the sentence fragment communication, the speakers can fulfill and realize the speaking leak and pragmatic intention which disuse by themselves. In this way, it can make the communication smoothly, so that, it will realize the Sentence fragment special value. That's all because of the interactions of the listeners'experiences, their cognitive, and the potential speaking atmosphere. It is pretty sure that the basic condition of using the uncompleted expression is base on a great deal of potential in common in formations. It is tough for the listeners to understand, if there are too many unknown in formations. Of course it will be a big hinder of the communication. At last, it will lead to fail.In the common communication, it is easier for the listeners to convert the characters. So when speakers express an uncompleted sentence, how should the listeners to convert? In fact, most breaking of the conversation is basic on that the speakers hope the listeners to add or we say to replenish the in formations they need. The speakers will give listeners some speaking ending signal, for example, to enlighten the last sound of the last word. According to the cooperation principle, the listener will convert naturedly. As for those speakers will judge and understand the listeners'converting intention, but not breaking the listeners.In a word, the interaction of economic principle, polite principle and the speaker's intention in communication make the sentence fragment exist. Also it proved sentence fragment's existing value. Tough compare with other speaking way, it doesn't have a unified pattern, we cannot give up studying it. Some practice proved that in some speaking situation sentence fragment is the best choice.Above all, the special point of this paper is that we expound the sentence fragment by both the speakers and listeners, not as the formers only focus on the speakers, neglect the listener's understanding and cognitive, also according to the theory, so we can get a deep and entirely understanding of it.
