英语课本中真实语言模型和人工语言模型的结合

教材在第二语言教学和习得方面发挥着重要作用。教师运用教材吸引学生的注意力并增强学生的学习动机是很有必要的。随着第二语言教学的发展和中国英语学习的改革,语言学习者们开始接触多种多样的英语教材,一些英语教材重点使用人工语言模型,另一些着重应用真实语言模型。人工语言模型可以帮助学生掌握基本的语言知识。真实语言模型能够激励学生并提高学生的交际能力。基于此,研究英语教材中真实语言材料的重要性,根据教材的编写原则证明,在英语教材中实现人工语言模型和真实语言模型的结合是重要和必要的。

Science Letters:Dynamic concision for three-dimensional reconstruction of human organ built with virtual reality modelling language (VRML)

This research studies the process of 3D reconstruction and dynamic concision based on 2D medical digital images using virtual reality modelling language (VRML) and JavaScript language, with a focus on how to realize the dynamic concision of 3D medical model with script node and sensor node in VRML. The 3D reconstruction and concision of body internal organs can be built with such high quality that they are better than those obtained from the traditional methods. With the function of dynamic concision, the VRML browser can offer better windows for man-computer interaction in real-time environment than ever before. 3D reconstruction and dynamic concision with VRML can be used to meet the requirement for the medical observation of 3D reconstruction and have a promising prospect in the fields of medical imaging.
