The experimental system of Chinese grammar teaching is concise in description, concise in system, comprehensive in description and rich in materials. It strives to implement the principle of combining grammatical form with semantics, inherits the achievements of previous grammar research, and absorbs the achievements of discussions on parts of speech and subject and object after liberation. It is the crystallization of the collective wisdom of grammarians in China and the most influential grammar system in the history of grammar development in China. The tentative Chinese grammar teaching system has spread all over the country in the form of middle school Chinese textbooks, which greatly facilitates middle school Chinese teaching and makes grammar science permeate all aspects of society and have great influence. At that time, not only primary and secondary schools and even universities were teaching according to the Trial System of Chinese Grammar Teaching, but also scholars were close to it in different degrees when writing.

The academic value of the tentative Chinese grammar teaching system is mainly reflected in:

1, pay attention to morphology, and describe the word formation and grammatical features of each part of speech in detail, so that the division of Chinese parts of speech has a scientific basis, and it is not necessary to copy the morphological theory of western linguistics, thus deepening our understanding of parts of speech.

2. Due to the lack of morphological changes in Chinese and the emphasis on expressing ideas, the Trial System of Chinese Grammar Teaching considers the subject and object from the relationship between the theme of discourse use and the subject in syntactic structure, and does not determine the subject and object by the meaning of giving and receiving.

3. Pay attention to the analysis of sentence structure. For example, a single sentence can produce a variety of sentence patterns according to different combinations of sentence components. Learning sentence patterns helps to master the structural rules of sentences.

4. Rich materials, comprehensive grammatical phenomena and in-depth description and analysis. For example, the sentence components of various parts of speech and sentences are described in detail, and the formats of "complex predicates" are described in detail for the first time, and the formats of condensed sentences are described in detail.
