A Study On The Comparison Between Continuous Time Adverbs "Yizhi" And "Yixiang" In Modern Chinese

Based on the “theory of Three-Dimensional grammar”，this articleputs the demands of teaching Chinese as foreign language as a starting point,and launched a series of comparison and analysis in detail from the semantic,syntactic and pragmatic aspects of continuity in modern Chinese adverbsof time “一直”and“一向”.Semantic feature dimensions. The semantic features of sustainabilityin common of“一直” and “一向” are ongoing on the axis to representevents. However，there are more obvious differences in the time domain ofthe steady state long and habits. In terms of features, we find that “一直” rather than “一向”on time characteristics in the system applicationis much wider. Such as“一直”could apply to events in the phase structureand end structure, in time within the structure can be used in the futuretense, in body structure can be used to start and continue, but“一向”arenot such usage. Features of other time structures, they use roughly thesame, but due to the differ of the two basic semantic characteristics, theirapplicable to specific locales are not the same.Syntactic function. With the help of the Chinese verb classificationresults of Chinese verb structure theory, this paper does systematicanalysis with the collocation case of “一直”and “一向”. We already cometo the conclusion that the acceptance of verb of“一直”is much higher than“一向”,“一直”status can be modified not only verbs, but alsomodification of dynamic verbs, and of elements associated with the verbis also more flexible. As the growing of action of verbs, the ability of“一向”to match with the verb has been declining, it cannot be modifieddirectly with the Vc3verb as a starting, and until it is completely notmodified Vd2verbs as the end. In terms of modifying adjective,“一向”focus on retouching and qualify the static events，and it has anadvantage is even more，and it can also directly modify some adjectives,but“一直”has no this usage. Co-occurrence in common either with theauxiliary verb is larger than personality, the main difference is frequencyof co-occurrence and the desired learning environment.Dimensions of pragmatic features. Both of them can appear in thedeclarative sentences and exclamations, pros and cons cannot appear in aninterrogative sentence. Because of the high power of action in imperative verbs,“一向”cannot appear in the sentence, but“一直”can.“一直”canbe individually composed of exclamations, but“一向”cannot. In the aspectof selection of a state, the applicable state of“一直”is broader than“一向”,“一向”cannot be modified in future classes, or the classes ofendless happened incidents in the sentences of “do” and “be done”,but“一直”is not subjected to such restrictions. In the structure of “belet” and “be done by”,and other analogous passive sentences,“一直”can modify the verbs that holding powerful action, but“一向”has nothis usage.
