中国大学MOOC: A well-written Introduction usually follows a clear logic. It often begins with the general background, followed by gaps in the research, specific questions addressed in the paper, and new approaches adopted, and ends with the research objectives of the study. Reorganize the different parts of the following Introduction. （请按照你的排序，直接输入大写字母，字母之间没有空格或标点符号）A. Growing interest in WPCs has been established by increasing numbers of publications including research papers, text books, review articles and patents. The competitiveness, performance and appropriateness of wood fibers employed as reinforcements in WPCs have been explored by considering the roles of surface modifications and fiber properties on the mechanical, thermal, and physical properties of WPCs. B. However, a review of the available literature indicates that an insightful understanding of how the properties of wood fibres, surface modification, polymer matrix and compounding technique influence the interface and functional properties of WPCs has not been gained. C. Finally, the implications of the findings of this study for the development of design and materials selection criteria for fabricating WPC parts are discussed in an attempt to ensure an efficient sustainable materials and process management practice. D. Research on wood polymer composites (WPCs) is attracting wider attention because stringent government environmental regulations are compelling industries employing inorganic fillers as reinforcements in polymer composites to search for less expensive, renewable and biodegradable alternative materials. E. In an attempt to increase the competitiveness of WPCs for industrial applications, the present work identifies and elucidates various factors influencing their functional performance by analyzing the associated interfacial bonding mechanisms and the functional properties.（请按照你的排序，直接输入大写字母，字母之间没有空格或标点符号，如：ABCE）
