Exploring two-dimensional (2D) magnetic heterostructures is essential for future spintronic and optoelectronic de-vices.Herein,using first-principle calculations,stable ferromagnetic ordering and colorful electronic properties are es-tablished by constructing the VS2/C3N van der Waals (vdW) heterostructure.Unlike the semiconductive properties with indirect band gaps in both the VS2 and C3N monolayers,our results indicate that a direct band gap with type-Ⅱ band align-ment and p-doping characters are realized in the spin-up channel of the VS2/C3N heterostructure,and a typical type-Ⅲband alignment with a broken-gap in the spin-down channel.Furthermore,the band alignments in the two spin channels can be effectively tuned by applying tensile strain.An interchangement between the type-Ⅱ and type-Ⅲ band alignments occurs in the two spin channels,as the tensile strain increases to 4％.The attractive magnetic properties and the unique band alignments could be useful for prospective applications in the next-generation tunneling devices and spintronic devices.

为了改进统编语文教材中“名著导读”板块的教学质量,以《童年》《西游记》等经典著作为例,以项目化学习为抓手,创新课堂教学形式,驱动学生主体化学习活动,拓展课程边界,提出初中名著阅读的项目化学习路径与策略,以期为一线教师提供相关思路.
通过对绿色指标学校报告的解读分析,发现部分学生在对信息进行整合、分析、推理和评价时,存在着比较大的困难,没有达到课程标准规定的基本要求.此外,报告数据显示他们的自信心不强、学习动机不足、学习策略与方法不得当.为此,上海市龙茗中学设计并实施了“天使成长帮教行动”,即任课教师与学困生进行结对,签订协议,明确双方的目标任务与责任,让每个孩子都能像“天使”一样健康成长.通过课前助学,让学生参与课前备课,提前预习教学内容;采用“学一退三”和“举三反一”的方法,帮助学生建立起新旧知识间的联系;通过延时评价,肯定学生的
