| There is both difference and relation between expert grammar and teaching grammar. The "difference" means the opposite features between the two grammar systems, The "relation" means mutual influence between them. The law of the mutual influence is mostly implied in the fact of grammar which only individual law presented itself sporadically in a few writings once in a while. Therefore, the aim of the thesis is to take comparatively systematical analysis about the law of the mutual influence.1. Starting with the characteristic relation between the expert grammar and the teaching grammar, comparison is carried out between the expert grammar system and the teaching grammar one from the following three steps: First, to compare "the Preparatory Chinese Teaching Grammar System" with the early expert grammar system; Second, "Middle School Teaching Grammar System Abstract" with the early expert grammar system; Third, the vertical comparison among the different teaching grammar systems. By the first and second step, the solid foundation has been laid down for cleaning up the development clue of the grammar system in Modern Chinese, and setting forth the opposite characteristic relation between the expert grammar and the teaching one. And the third step is to clean up the development clue of the grammar system and set forth the opposite characteristic relation between the expert and the teaching directly.2. As two opposite sides, the expert grammar and the teaching grammar has also being permeating mutually: The expert grammar has produced profound effect on the teaching one from aspects such as view, thought and method etc., which the grammarian's works produce some influence on the teaching grammar, such as introducing some technical terms, while the collective discussion influences on grammarian's view of grammar and Chinese, then has brought a fundamental change to the expert grammar and the teaching one. Conversely, the teaching grammar also has had reaction on the expert one by its inherent mechanism that declines the expert autonomously or throws it away actively.3. The expert grammar and the teaching one should converge after each developed alone in the certain period, and they also can do so. The prominent divergence has appeared at present between them, we have comprehended seriously much side effects brought about by the divergence from point of view of the Chinese teaching for middle school. Finally, we have looked for the origin of the divergence, and summed up the experience and lessons in the process that success from the expert grammar drew on into the teaching grammar, put forth our suggestion and test for constructing new teaching grammar system. |
