The construction of Chinese traditional sports teaching material library is in line with the trend of the times and the needs of the masses. By using the methods of literature, system design and logic analysis, this paper analyzes and studies the various aspects of the construction of teaching material library of Chinese traditional sports items. It is found that the construction of Chinese traditional sports teaching material library is of great significance to teachers, students, curriculum carriers, social trends and so on. Its functions of data storage, unified management, secondary dissemination and mutual promotion of teaching are obviously prominent. The platform, chapter, page, content design structure is clear, logical and correct;the goal of its construction is to form the theoretical system of Chinese traditional sports teaching material library, to use the traditional and modern teaching methods, to carry out the two-way teaching mode of combining theory with practice, and to realize the two-step teaching strategy of online connection and offline. It puts forward the construction requirements of adhering to the uniqueness and integrity, diversity and unity, generalization and consistency, expansion and openness, so that the traditional sports in our country can be spread and inherited indefinitely, so that this excellent traditional culture will endure forever.展开更多

How to memorize vocabulary effectively is a troubling issue both for learners and teachers. The experiments show that the more closely connected between pair words, the higher rate of recurrence with correctness. Focusing on the connection of morphemes in Chinese vocabulary teaching can accelerate students＇ memories of new words. The author believes morpheme teaching is also evidently effective for those Chinese learners using Chinese characters in Japan. However, after examining the order of words with same morphemes in 14 elementary Chinese textbooks, the authors found that current textbooks have not provided a list of words with same morpheme thus imposing learners＇ memory burden due to learning repetitive words. Meanwhile, this paper proposes ＂radial networks＂ among morphemes with same words, also promotes the expansion of vocabulary by morpheme association.展开更多

Our understanding on patterns and controls of wood physical and mechanical properties could provide benefits for forestry management and bases for wood application and forest tree breeding. However, current studies on wood properties mainly focus on wood density and ignore other wood physical properties. In this study, we established a comprehensive database of wood physical properties across major tree species in China. Based on this database, we explored spatial patterns and driving factors of wood properties across major tree species in China. Our results showed that(i) compared with wood density, air-dried density, tangential shrinkage coefficient and resilience provide more accuracy and higher explanation power when used as the evaluation index of wood physical properties.(ii) Among life form, climatic and edaphic variables, life form is the dominant factor shaping spatial patterns of wood physical properties, climatic factors the next, and edaphic factors have the least effects, suggesting that the effects of climatic factors on spatial variations of wood properties are indirectly induced by their effects on species distribution.展开更多
