My name is Nick Vujicic. I was born without limbs (四肢), and doctors have no medical explanation. As you can imagine, I was faced with many difficulties. My
father thought I wouldn't live for very long, but tests proved that I was a healthy
baby boy just with limbs missing.
Understandably, my parents had strong fears of what kind of life I'd be able
to lead. The law in Australia didn't allow me to study in a main-stream (主流) school because of my physical disability(身体缺陷). However;,my mother fought for the
law to be changed, I was one of the first disabled students to go into a main-stream school.

was in my early years of school where I had uncomfortable times of feeling not being accepted because of my physical difference. It was very hard for me to get used to,
but with the support of my parents, I started to develop attitudes (态度) and values
which helped me go through these difficult times, I knew that I was different but
on the inside I was just like everyone else. There were many times when I felt so
low that I wouldn't go to school. I was encouraged by my parents and tried starting
to make friends by just talking with some children. Soon the students realized that
I was just like them.
I am now twenty-three years old and have completed my university study. I am
also a speaker and love to go out and share my story wherever possible. I have developed talks to encourage students to face their problems. Writing several
best-selling books has been one of my dreams and I hope to finish writing my first

Jazz is a type of music that was invented(首创) around 1900 in New Orleans in the south of the USA. There were many black musicians living there who played a style of music called blues music.

民族传统体育项目
民族传统体育项目——跳绳、滚铁环进体育课堂 长期以来,由于受竞技体育、体质教育的影响,我国中小学校体育课程主要以竞技运动项目为主要内容。体育课程教学从动作的学习到场地器材的配置规格,都是竞技化,西方的,很少考虑大部分学生的学习兴趣、需求和可接受性。相对外来竞技运动项目而言,我国民族民间传统体育既有很高的娱乐价值,又有很高的文化价值,许多民族民间传统体育项目不受场地、器械设备、年龄等条件的限制,既经济又便于开展,有好多内容以其娱乐性,趣味性等特点,深受学生的欢迎,是平时学生喜爱并在课间玩耍的项目,把这些学生喜闻乐见的传统项目进行开发改造引入于小学体育课堂中来,不仅是对学校体育内容的补充和发展,而且会极大地丰富学校体育的课程内容。本课题以西城少年宫幼儿艺术班为研究对象,采用文献资料法、问卷调查法、教学实验等方法,对当前本小学民族民间传统体育项目的开展现状进行了调查分析。民族民间传统体育在小学校体育教学中的应用性研究,包括调查研究和实验研究两大部分,调查部分主要阐述了民族民间传统体育项目在目前小学体育教学中的现状、民族民间传统体育的特点及教学功能和价值、民族民间传统体育在学校体育教学中是否可行和其进入学校体育教学的途径。实验研究就具体的两个富有地方特色的民族民间传统体育项目跳绳和滚铁环在学校体育教学中如何进行教学改编,在教学过程中应遵循哪些教学原则,采用何种教学方式,提出了三个实验假设:学生对跳绳和滚铁环这两个体育项目很喜欢;跳绳和滚铁环这两项民族民间传统体育项目对学生的身体素质的锻炼效果与现代体育项目的效果差别不大;跳绳和滚铁环这两项民族民间传统体育项目适宜在小学推广。通过教学实验验证这两个项目深受学生喜爱,这两个项目具备推广的条件和价值,这两个项目能对学生的身体素质起到锻炼效果。并通过这项教学实验为其它的民间传统体育项目如何进入学校体育教学提供一些参考和借鉴因素,得出民间传统体育项目适合在学校体育中开展,应大力推广。 关键词:民间体育项目小学体育教学 以增加学生对民族传统文化的了解程度和自豪感。体育教师和学生传达课程改革新思路,让他们改变传统体育教学观念,从思想上重视民间民族传统体育教学。先将近年来课程改革中有关民族传统体育教学方面的新成果传达给学校的领导和参与实验研究的体育教师。在教学中,我们主要通过实国家特别重视少数民族传统体育项目的发掘与研究工作,已逐步整理出了许多富有民族特色体育项目。 发掘民间传统项目进课堂,丰富体育教学的内容。我宫从上世纪200年代开始,对流传于民间的传统体育活动—滚铁环进行了发掘、研究,并结合现代运动的特点,进行了创新,把滚铁环这项体育活动引进了我宫的体育课堂。现把我们发掘、整理、研究、创新的滚铁环运动介绍如下: 1.铁环队列练习。其一,学生成四路纵队或二路纵队,听统一口令向前、向后、向左、向右滚铁环走。转身时,滚环用手帮助控制。其二,滚铁环进行S’’走,或进行螺旋形和反螺旋形行走。可提高队列练习的兴趣,培养学生良好的组织纪律性。 2.铁环操或舞。手持铁环跟着音乐的节奏做各种器械操或单、双人、多人舞。以培养学生的音乐素养和形体美的教育。 3.滚铁环跑。可滚着铁环进行快速跑、耐久跑、上下坡跑等。提高学生进行快速跑、耐久跑的兴趣,发展学生跑的能力。

浅析我国高校民族传统体育专业发展的现状及趋势(一)
浅析我国高校民族传统体育专业发展的现状及趋势(一) 【摘要】民族传统体育是民族传统文化的产物与载体,民族传统体育专业在高校的开设是对文化的继承与发展,在新形势下新文化的发生与入侵将对民族传统体育发生决定性影响,文章通过对目前传统文化下我国高校民族传统体育专业发展的现状进行研究,并对新文化下民族传统体育发展方式及方向进行了前瞻性分析。 【关键词】高校;民族传统体育;传统文化;新文化 随着我国经济的飞速发展和人民生活水平的不断提高,人们对健康的关注程度也越来越高,这就为民族传统体育的蓬勃发展奠定了社会基础。民族传统体育有着其独特的自身魅力,民族传统体育在社会主义先进文化建设中扮演的角色越来越重要,它是我国城乡居民体育锻炼的主要项目,区域性广、练习方式多样,可以适合任何年龄、阶层的人群。民族传统体育的社会价值通常是通过人们参与来实现的。发展民族传统体育不仅能够增强各民族人民的体质,丰富群众文化生活,建立科学的、现代化的生活方式,有利于塑造体格健壮和精神高尚的一代新人,同时还是富国强民、振奋民族精神、激发爱国热情、增强民族凝聚力、提高民族素质的一种重要社会活动。开展民族传统体育活动有利于协调人际关系,增进各国民族交往和国际友谊,对人类的进步有着重要的作用,它的发展是构建和谐社会的重要组成部分。 一、国高校的民族传统体育专业设置的先天性基础 我国民族传统体育伴随着五千年的悠久历史产生、衍变,成为我国历史瑰宝的一部分,是我国民族文化的重要载体,是千百年来民族文化的结晶,长久以来为人们所喜欢,且为我国在不同时期的进步作出了重要贡献,因此对民族传统体育的研究也就是对中国人文历史的研究。民族传统体育随着我国的发展,构建社会主义和谐社会已成为国人的共识,这为民族传统体育的发展带来机遇,也必然会带动和促进整个社会的和谐发展。 我国的民族传统体育主要有以下几个特点: 1.种类的多样性和包容性,据《中华民族传统体育志》统计,我国的民族传统体育项目种类多达977种其中,汉民族的项目有301种,其他55个民族的体育项目多达676种; 2.分布的地域性,根据我国56个民族根据民族传统地域性特征和全国少数民族地区分布,可分成五大板块东北板块、西北板块、西南板块、中南板块及中东板块,五大板块由于民族分布的地域不同气候的变化不同民俗民风的差异性,各民族便形成了各自独具特色的传统体育项目; 3.民俗性和娱乐性,在民族传统文化中对民族最具凝聚力的要算民俗文化它将朝夕相处的民族成员凝聚在一起,并且将具有相同文化背景的人们也团结在一起。同时,风俗习惯既受到民族因素的影响,也受到地域因素的制约。地域经济、政治、宗教、语言的长期影响互相依赖铸成多姿多色共存共荣的民俗特征。如端午、中秋、春节仍然是百姓重视、影响最大的传统节日舞龙、高跷、狮子等娱乐体育活动成为超越时代存在的一种符号和民族传统。 4.资源的整合性,体育资源具有文化的多样性、广泛性、地域性、多功能性等,内含观赏性、健身性、文化娱乐性、民俗性等内容随着经济和社会的发展体育文化的内容、范围、形式。规模不断发展通过资源的整合其质也将不断发生变化因此,它的整合和利用能显示传统文化的本质属性特征,彰显传统体育文化价值能产生积极的社会效应和经济效益。这些特点也就是我国高校民族传统体育专业设置的基础。 二、我国高校民族传统体育专业的现状 我国高校民族传统体育专业既是传播体育文化,促进人类文化发展的桥梁,同时又是承载我国优秀传统体育文化,弘扬民族文化特色的重要途径。1989年,民族传统体育才成为本科专业,其专业尚处于摸索、模拟建设阶段,民族传统体育专业的教学是参照体育相关学科而设置的。目前民族传统体育发展还有许多局限性,如基础理论薄弱没有重大发展与突破,自身价值和本体目标模糊。
