简介:学生党员先进性教育是高校党员先进性教育活动的重要组成部分。立足高校学生党员队伍和党建工作的现状,结合“三个代表”重要思想对党员先进性的新要求,全面强化高校学生党员的先进性教育,充分发挥学生党员的先锋模范作用,加强和改进学生党建工作,使学生基层党组织切实成为凝聚大学生群体的核心力量,对于培养中国特色社会主义事业的建设者和接班人具有特殊的重要意义。在新时期如何理解学生党员的先进性、怎样体现学生党员的先进性、如何把先进性教育贯穿于学生党建的全过程?这些问题是高校学生党建工作中值得研究实践的问题,也是本次保持党员先进性教育活动的意义所在。
简介:the factors of affecting the classroom dynamics and the present situations of junior English classroom. In order to provide teachers and students with a dynamic English classroom in language learning and teaching,different students and different contents. Only when the teachers and students have a dynamic classroom atmosphere can the quality of teaching and learning be improved efficiently. ,audio-visual aids and other teaching media play a more and more important role in English language teaching and learning
简介:[8] so the teacher plays a very important role in English teaching and learning in junior classroom. The teacher is one of the significant factors in creating a group dynamic atmosphere in language learning. We often say if the teacher wants to give the students a glass of water,the traditional teacher-centered teaching is not adequate for the classroom teaching. Now a lot of Chinese teachers are conscious of the importance of training students’ communicative ability in the junior English classroom teaching and traditional teacher-dominated approach is gradually being shifted to a learner-centered one. The teacher tends to adopt a more flexible teaching style in the ELT classroom and provides more opportunities for students to practise and talk freely in English. And the teacher needs to think of language learning as students’ personal,[5] A positive classroom dynamics in the English language classroom will benefit both the teacher and the learners in a number of ways. Firstly
简介:用1984-1999年期间的地极坐标序列和两个大气角动量序列。分析了不同Chandler周期和品质因子Q的取值对Chandler摆动周期激发的功率谱密度,以及观测激发与大气激发之间的相干系数和相干相位的影响,结果表明,不同Chandler周期和品质因子Q的取值对观测激发的功率谱密度,以及观测激发与大气激发之间的相干系数有很大影响。因此,在分析Chandler摆动的观测激发与地球物理激发的关系时,不能仅以观测激发与某个地球物理激发序列(如大气激发)的更好逼近来选择Chandler摆动的最佳周期,因为Chandler摆动是多种地球物理激发共同作用的结果。
