文化的传播需要一定的载体.体育传播是以竞技比赛、体育活动、娱乐休闲等为载体的交流和信息交换行为.我国古代体育文化总是附着于军事、竞技游戏以及养生健身、侠义精神以及宗教仪式等特定的社会现象中继承和传播的.

《云南少数民族文化传承论纲》一书对民族文化传承问题进行了详尽的分析,并在讨论中作出了演绎和逻辑展开,既研究文化现象,又关注现实问题,内容所及和探讨远远超出了云南少数民族文化本身.本书分为理论篇、论证篇和开发篇三部分.

如今,报知春节迫近的已经不再是腊八粥的香味,而是媒体上充满压力的热火朝天的春运了.每入腊月,春运有如飓风来临,很快就势头变猛,愈演愈烈;及至腊月底那几天,春运可谓排山倒海,不可阻遏.每每此时我都会想,世界上哪个国家有这种一年一度上亿人风风火火赶着回家过年的景象?

生活离不开美丽,美丽来源于自然.现代人的生活节奏快、压力大,通过与植物、花友的互动会给生活带来一些乐趣,而今,最为热气腾腾的不外乎多肉植物了.依照17世纪英国植物学家的解释:多肉植物-多水叶的植物.即此类植物仍具有标准植物(Typical Mesophyte)之形态,而仅为叶、茎、根的肉质化而已,大部分多肉植物为适应恶劣环境所需,具有夏眠或冬眠的习性.广义的多肉植物是包含仙人掌在内的.而狭义的则指除仙人掌以外

日前从同事李智博士处得到著名哲学家张世英先生赠送给我的新著《中西文化与自我》,不禁欣喜若狂,因为这部著作是我期待数月的.此前在(《北京大学学报》上连载的六篇文章《中华精神现象学大纲》

清同治十一年(1872),李鸿章指出,由于外国列强的侵略和影响,中国社会出现了"三千年未有之变局".此语一出,不胫而走.他的话简明扼要,是对中国时局的深刻概括.自西周到清晚期的3000年,中国经过多次朝代更替,经过数度异族入侵,屡生变局.但清末出现的变局在深度和广度超过以前每一次的折腾.从根源上说,是最先发生在英国的工业革命引发了世界的近代化浪潮,对古老中国的封建农耕社会产生巨大的冲击.

二语词汇习得中的石化现象直接阻碍了学习者的语言表达及运用能力.二语习得者如果过分地依赖于高频词汇,结果则是其产出性词汇无论在广度还是深度上都很难进一步提高.因此,教师应该鼓励并在教学中采用一定的教学策略促使学生尽量多运用刚学的新词,而非一味依赖以往熟知的高频词汇,使学生的语言表达更加准确、恰当和丰富,从而促进其英语水平的不断提高.

自有人类文明以来,伴随着人们的造物活动,设计就存在于人类文明发展的每个时期,并且与文化的形成息息相关、不可分割.设计发展至今已不仅仅是一种单纯意义上的造物活动,更是一种文化形态、文化创造.因此现代设计包含了广义上的物质技术、社会规范和理念精神的文化概念,成为了融会物质文化与精神文化综合的一种独特文化形式.设计作为文化的形象显现,在每个时代都有自
