The Explore Of “Ruguo(如果)A,Jiu(就) B”

“Ruguo(如果)A,Jiu(就)B”,as a representative sentence of hypothetical sentence,belongs to the causal complex sentence,according to the theory of Xing Fuyi.“Ruguo(如果)A,Jiu(就)B”,as a sufficient condition relation expression,contains rich and rigorous logic reasoning,having a strong style inclusion,containing the scientific style,the poetry style and literary style.It is used in both written and oral communication.but it is continued to studied in its rich semantic content and special pragmatic value necessarily and urgently.Under the framework of “small triangle” theory, the research of this sentence content mainly includes four aspects.The aspect of forms is divided into three parts.In the hypothesis clause,the conjunction word,namely“Ruguo(如果)”,can be replaced by“Wanyi(万一)”and“Yaoshi(要是)”conditionally.But they are different in the style of use and the possibility of implementation;If there is“Dehua(的话)”in the hypothetical clause,the conjunction word“Ruguo(如果)”can be omitted.In the result clause,the conjunction word“Jiu(就)”can be replaced by“Bian(便)”.In addition it can be added“Ze(则)”or“Na(那)”before the conjunction word“Jiu(就)”.Throughout the form characteristics of the whole sentence,the former and the latter can be mutually displacement.When clauses A and clauses B constitute comparable structure,this sentence can express rich content.The language content is divided into four parts. Conditionity refers to the sentence can express only sufficient conditions. In the aspect of preset, the sentence can express possible preset and opposite preset. Analyzing the cognitive level of this sentence, we should determined the sentence as a clause across class. In the aspect of subjective speculation, when A and B is consequent restriction relationship, the subjective speculation level is 0.5 < P {B/A}< 1, when A and B have reverse restriction relationship, the subjective speculation level is 0 < P {B/A} < 0.5, when the relationship between A and B are not restricted, the subjective speculation level is P {B/A} = 0.5. Objectively reflective level is P {B/A} = 1. In addition this sentence can not only express assumption relation, but also express purpose, inference, selection and other relations.In the aspect of pragmatic value, the sentence can be divided into nine types according to the true or false of A and B objectively. The sentence can express sarcasm, ridicule, urgency, advice and other special pragmatic value. At the same time, we can derive four kinds of pragmatic model.In the last part,we compare the two sentence patterns“Ruguo(如果)”and“Ruguo Shuo(如果说)”from form,content and pragmatic value.“Ruguo Shuo(如果说)”can be connected by twist words while“Ruguo(如果)”can not.“Ruguo(如果)”can express possible preset and opposite preset while“Ruguo Shuo(如果说)”can express the fact preset.“Ruguo(如果)”can express choose relations while“Ruguo Shuo(如果说)”can represent response relationship.The pragmatic value of“Ruguo Shuo(如果说)”mainly leads to the topic and explanation,different from the sentence pattern of“Ruguo(如果)”.
