Topic Marker "on", "", "as For The" Study

"Topics" concept has always been a concern of an academic grammar one of the hot. This paper tries to one aspect of the topic "topic marker" as a starting point to study. Specific study "About", "For," "As" for topics markings. In the past to the "About" "For" "As for the" three words a lot of research, but more from the surface of the three prepositions are concerned about the difference in the use of, and the distinction between standards are simpler. And these three words to make a clear marker to study the subject of very little less. In this paper, from the perspective of their topic tags to study, in addition to outside of the preamble and conclusion, this article is divided into four chapters.The first chapter of "X in the" topic sentence, the nature, type and common now. "X in the" topic sentence, located in the following three sentences in the:T, (S) VO, in which some of the syntactic level S to the space form; TSVO; TVO. There are also "on the" special function marking discourse. On this basis, then examine the distribution of these three topic sentences, pause, then attached to the word, with a total of four are in the form of features. Distribution in the first sentence, also in the end of the sentence. Pause regard, "X in the" behind the use pause, you can not use. TSVO and TVO sentence did not stop T, (S) VO sentences in a standstill, the general tone of the accompanying words or pauses when quasi-particle. Aspects of the attached word. "X in the" tone words attached conditions are rare; three words can bring quasi-particles, and more common, internal differences are significant. With respect, "X in the" 22 can be stacked with, apply, MS, combined.The second chapter focuses on description of "X in the" topic sentence of the syntactic and semantic features looming. Characterization of the composition topic "Y" of the syntactic function is free; "Y" in the alleged exclusion of non-fixed component side, the main means by a fixed component as the class. "X in the" mark of the topic is the argument of the main types of topics and language that topic and domain. On "X in" the excitement, is a complex issue because it involves discourse. It is not only a relationship with the type of topic, but also with the "Y" feature, subject and a predicate argument relations issues, relevant sentences are involved.The third chapter examines the "X in the" Discourse functions. "X was" as topics of discourse marker functions when there are personality similarities. With the topic of enhanced contrast, and provided assistance to function in common. Personality of the "on" message function, "for" possession of functional, "As for the" transformation of subject features are outstanding. "X was" out of context in the case, the three can often be replaced with ease. In the specific context, the situation is more complicated, this will involve a mark of special words for each function. In most cases they are their duties, but sometimes, the "About" is also to limit or change the function of new topics, "for" has prompted a new topic or change the function, "As for" a prompt or limit the functionality.Chapterâ…£focuses on "X in the" Internal Differences. Three in the tagging feature, topic types, discourse features and the accompanying words of four different aspects. Attached mainly to the accompanying words tone words and the attached two quasi-particle. Whether attached or quasi-modal particle particle, the difference was relatively large, and according to our study, most of the time attached to the word can be omitted, the sentence does not affect the degree of expression of qualified, so we do not recommend it as the framework.We hope that through research, trying to syntax, semantics and pragmatics plane as the key link, detailed description of the "About", "For" and "As for" doing the three topics marked effect of this common, have in common, What is personality? Under what circumstances can common, and when not to do so? When they surfaced freedom, when they need to forced to use it? This paper tries to achieve a breakthrough in these areas.
