如何表现广播操的优美性

广播操作为具有中国特色的学校体育项目,不仅有健身价值和积极向上的教育意义,更能提高学生的审美感。通过对学生做操情况的调查,发现学生对操的准确性掌握较好,但缺乏美感。在广播操日新月异的时代,身为学校体育工作者要跟上时代步伐,深化新课程要求,促进学生身心全面和谐发展,掌握操的美感特征,抓动作姿态、速度、力度,提高动作优美性。     

简论健美操动作美感的三要素

阐述了健美操动作中的姿态、速度、力度三要素,为进一步理解和学习健美操提供了理论支持。同时对这三要素的学习使我们达到动作的形式与精神美感的内容和谐统一,从而增强健美操的优美性及表现力,促进健美操运动的发展。     

浅论体育教学中运用多媒体技术的价值

教育现代化的重要标志是教学手段的现代化，而现代信息技术在学校教育中的运用越来越广泛，体育教育也不例外。在体育课上，正确地充分利用多媒体组织教学可以增加课的容量；加大教师对学生的指导和纠正错误动作的力度；能充分调动学生的学习积极性和增强学生的自学能力和创造能力。利用好多媒体组织体育教学是可行和完全必要的。     

浅谈体育教学中的动作示范

体育课的教学区别于其他文化课的教学。体育课就是要用身体说话，用动作说话，其教学的目的就是要让学生掌握教师所做的动作，使学生学习并掌握一定的运动技能。因此，如何综合利用各种教学手段，有效地揭示技术动作的内在规律，强化学生掌握技术动作的心理素质，对完成体育教学任务有着非常重要的作用。     

对徒手体操教学问题的思考

徒手体操是基本体操的重要部分，它是以人体解剖、生理特点为科学依据，以任务、目的、要求而系统地编写的身体练习的徒手活动，因而它对体育教学与训练和健身具有重要意义；本文从徒手体操的历史进行，解读徒手体操不平凡的经历，进一步探讨徒手体操的社会地位和社会价值；同时从徒手体操的技术因素及其创编规律，探索以适应现代社会需要的徒手体操，并提出自己的观点与同行讨论。     

浅谈讲解与示范相结合的课堂教学艺术

教师的讲解与示范是体育课教学中最主要的、最基本的教学方法．正确处理这两者之间的关系，是提高教学质量的重要因素之一．本文仅对讲解与示范的相结合问题，谈点体会，供参考．1先示范，后讲解初学阶段，在学生对某一新教材从未接触、比较生疏的情况下，教师应在介绍动作名称后，先做一次示范，使学生了解动作的形象，在此基础上，再讲述所学动作的要领、完成方法以及对动作的要求．必要时可以再做一次补充性示范或强化性示范，以加深对动作的理解．先示范后讲解的方式，一般在低年级学生中运用较普遍、广泛，因为他们的特点是对具体的形…     

浅谈运用示范导入法提高排球技术教学效果

示范是体育教学中常用的教法之一，是教学过程中不可缺少的一个重要环节．科学合理地运用示范，正确引导学生积极地观察、思考和分析，以加大学生理解能力、分析能力的锻炼力度，激发学生学习兴趣，使学生的有意注意始终集中在课堂技术学习和动作练习上，从而提高排球技术教学效果．     

徒手体操简图绘制要点

徒手体操,动作简单,形式多样,内容丰富。一般不受年龄、性别、健康水平及场地设备的限制,而对增进健康又有一定的实效,因而是一项宜于开展的群众性体育锻炼项目,也是学校体育教学中必不可少的重要内容。为了便于教学和推广,徒手体操一般是采用图解的形式来表达动作的过程和形象。其中简图是最常用的最方便的一种图解方法。这是因为简图有如下优点:一、绘制简易,图能示意。二、在制订课时计划时,采用简图记写,可以节省时间和篇幅。三、在课堂教学中,采用简图描述,便于剖析动作。四、在观摩学习时,采用简图速记,可快速而完整的搜集整理资料。五、利用简图描绘、创编和设计新的徒手体操动     

试论高等体育“立体式教学模式”的建立

从全面推进素质教育的视角，对高校体育课程教学模式进行理论研究与思考，提出了新的体育教学模式——“立体式教学”．并利用两年的试验教学和问卷调查，证明“立体式教学”模式能达到提高学生对体育课的兴趣，提高学生对所传授的技术动作的准确理解和应用的能力，提高学生参与体育锻炼的愿望，能更好地培养学生终身体育锻炼的意识．     

学校体育课教学中口诀的应用

<正> 在学校体育课教学过程中,学生学习新授课技术动作时,除了体育教师的示范动作外。还要通过教师对技术动作的讲解,达到了解技术动作结构的目的。要想让学生充分了解技术动作,并在大脑中形成正确的动作表象,就需要大量的反复讲解时间,这会使学生练习的次数减少,降低了新授课的教学密度,影响学生学习技术动作的教学效果。而且由于讲解的内容过多,学生不能将内容记住,往往又在技术练习中不知所措,更加影响了体育课的教学效果。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
