A Study On The Relationship Between Conditional Sentences And Hypothesis Conditional Judgment

This paper discusses the hypothetical composite conditions throughout the judge corresponding with the wrong with conditional clauses should be relationship. Wrong should be the core of the problem lies in not the classification of the corresponding judgment of conditional complex sentence classification and hypothetical conditions of the composite. Firstly,the conditional clauses is divided into a sufficient condition, essential condition to judge, necessary and sufficient conditions of judgment, and the language of conditional complex sentence points in order to fully conditional and unconditional, necessary conditional sentence, did not put forward a sufficient and necessary condition of definite sentences of this concept, also joined the unconditional sentence. This makes the classification and hypothetical conditions judgment condition does not correspond to the complex sentence. Therefore in this paper, two aspects of logic and language, three kinds of relationship between the logic connotation by analyzing the sentences in the two sentences of A and B were expressed by the sentence semantic plane and reclassifies the conditional compound sentence, complex sentence into conditions fully conditional, necessary condition and sufficient condition sentence, at the same time without A, the logical connotation of conditional in B according to the relationship between the two, will express fully relationship, necessary and sufficient complex sentence relations are divided into three classes among the above sentence.Secondly,at the same time in the necessary conditions and sufficient conditions of a sentence, a part of the sentence A and B itself has sufficient conditions or necessary conditions for the relationship, can be directly constitute sufficient conditions or necessary conditional sentences, these sentences and the logical semantic relationship corresponding logic relationship. But there is one part of the sentence will not have the relationship is necessary or sufficient conditions of A, B through the associated word connections form sufficient or necessary condition sentence. So this kind of sentence logic relationship and the logical semantic relations do not correspond.Thirdly, necessary and sufficient conditions related words in the language sentence usually use or table or tables full necessary conditions are connected, cause the necessary and sufficient condition is not split out from the necessary conditions and sufficient conditions of a sentence. Necessary and sufficient conditions for a sufficient and necessary condition of the outer can be divided into performance for the sufficient condition in the performance of the sentence and the sentence representation is the necessary condition.Finally, unconditional sentences are usually single. But a careful study of the relationship between non conditional sentence A and B Logic Connotation, we found that A, B, the sentence is not unconditional, is conditional, the associated word "whether" just from some conditions, does not affect the logical relationship between the sentence itself, B A. According to A, B or between sufficient or necessary or sufficient and necessary logical relation will be unconditional sentence re divided into full conditionals, necessary condition and sufficient condition for the sentence.
