对于花草,我向来不那么热衷,养花,更是糟蹋生物,总是等不到花开便夭折,不是渴死就是涝死,颇有一种负罪感,于是,暗自决定不再养花.
单位搬迁时,新办公室突然多了一种不知其名的植物,绿葱葱的,赏心悦目,一片片心形的叶子甚是肥硕,油光发亮,像抹了蜡油似的,茂盛得也很快,没几天就会有新叶冒出.只是它们只管生长不开花,我不禁纳闷了:这究竟是什么花?长得如此欢喜,春去春又回,就是不开花,完全无视春天的存在.出于好奇,后来问了浇花师傅,才知这种植物叫绿萝,又名黄金葛,也叫抽叶藤,原产热带雨林,性喜潮湿半阴环境,可水植,也可泥栽,可谓水陆"两柄",生命力十分顽强. 相似文献

中国古代,对于人的排泄问题,其实很看重,庄稼一枝花,全靠粪当家,农村的人,一粪一溺,都浪费不得,要肥自家的田。因此,无论马桶也罢,厕所也罢,总而言之最后都要沤了肥田,所谓肥水不落外人田,就是这个意思,如果出门来不及回家方便,粪便掉在别人家地里,无论如何都会有点懊悔,特别敬业的,往往会找个家什捧回来。南方大一点的集镇,也有人建公厕,这种公厕,跟公益无关,属于私人的赢利事业,用来专门收集赶集人的粪便,然后卖给农民。当然,对于赶集的农民,一般都指望不上,但是对于那些走街串巷的艺人、手艺人和商人,却也是个便利。一些坐商,在买卖商品之余,卖点白拣的粪便,也是小补。 相似文献

春朝,幼苗破土,疯狂地长高再长高,那是小苗的梦在舞;夏晨,碧水涟涟,彩花轻颤,那是风儿的心在舞;秋日,黄叶纷飞,流连复流连,那是叶在用生命起舞;冬夜,雪花飘飘,盘旋再盘旋,那是白雪在用灵魂起舞。 相似文献

Information is presented about the organization of graduate studies, based on questionnaire responses of 582 coordinators of Canadian graduate programs. These coordinators, who were representative of disciplines and geographic regions, provided information about a wide range of matters, including enrolments, staff, admissions, supervision, research, publications, financial support, teaching experience, and completion rates and times. Many substantial differences were noted among the percentage frequencies of responses for departments classified by discipline and size. For example, students were perceived to choose their doctoral theses topics themselves much more frequently in education, social sciences, and humanities than in engineering, medical sciences, physical sciences, and biological sciences. Also, departments with smaller numbers of full-time graduate students tended to provide all doctoral students, with some teaching experience to a greater extent than did larger departments. 相似文献

实践的自由与美的范畴 总被引：10，自引：0，他引：10
张玉能 《华中师范大学学报(人文社会科学版)》2003,42(1):47-53
人，作为个体的生存，从实践（以物质生产为中心）出发才逐步生成，而在实足走向创造的过程中，人们才不断达到一定的自由境界。正是人的实践－创造的自由使自然人化，人也人化，从而产生出人对现实的审美关系；这种审美关系体现对象之上就是美，而体现在人本身之上则是美感。人类的实践－创造的自由同样是一个历时性的过程和一个共时性的结构，因此，它不仅有不同的自由程度和不同的自由境界，而且还有自由，反自由，不自由，准自由等几个维度；与这些不同的自由给度相关便形成了美，丑，柔美，刚美，悲剧性，喜剧性，滑稽，幽默的相应的美的范畴，并形成各个美的范畴之间的过渡，转化，对应等关系，从而形成一个完整的美的范畴体系。 相似文献

劳伦斯与非理性主义 总被引：1，自引：0，他引：1
刘洪涛 《北京师范大学学报(社会科学版)》2006,(3):41-48
以叔本华、尼采、弗洛伊德为代表的非理性主义是劳伦斯小说创作的思想基础。受叔本华影响,劳伦斯把生存意志作为人物行动的基本动力,这主要表现为向性力和精神占有欲。受尼采影响,劳伦斯赞美躯体,重视生命的内在能量和自我超越性,并与基督教决裂,成为西方基督教道德观的激烈批判者。劳伦斯在性与无意识这两个领域,对弗洛伊德精神分析理论有接受,也有超越。弗洛伊德与劳伦斯都把性、无意识与文明对立起来,但弗洛伊德进行的是否定性研究,强调对其疏导和控制,劳伦斯则认为性与无意识是原初的创造性力量,是生活的源泉,是对抗人之社会化和理性化的正面力量。非理性主义丰富和深化了劳伦斯对现代人心理世界的理解,加强了他的小说的社会批判力量。 相似文献

A teacher and a college student explore experimental science and its history by reading historical texts, and responding with
replications and experiments of their own. A curriculum of ever-widening possibilities evolves in their ongoing interactions
with each other, history, and such materials as pendulums, flame, and resonant singing tubes. Narratives illustrate how questions,
observations, and developments emerge in class interactions, along with the pair’s reflections on history and research. This
study applies the research pedagogy of critical exploration, developed by Eleanor Duckworth from the interviewing of Piaget
and Inhelder and exploratory activities of the 1960s Elementary Science Study. Complexity as the subject matter opens up possibilities
which foster curiosity among participants. Like Galileo, Tyndall, Xu Shou, and others, this student recurrently came upon
new physical behaviors. His responses to these phenomena enabled him to learn from yet other unexpected happenings. These
explorations have implications for opening up classrooms to unforeseen possibilities for learning.
Teaching . . . is more about a conscientious participation in expanding the space of the possible by creating the conditions for the emergence of the not-yet-imaginable. . . . Teaching, like learning, is not about convergence onto a pre-established truth, but about divergence - about broadening what can be known and done. In other words, the emphasis is not on what is, but what might be brought forth. Teaching thus comes to be a participation in a recursively elaborative process of opening up new spaces of possibility while exploring current spaces. (Davis & Sumara, 2007, p. 64)相似文献

In this article, we present certain topics such as quadrature of planar regions, introduced prior to the invention of calculus
by Newton, and consider his other mathematical contributions, to binomial theorem and infinite series, cubics, theory of equations
and imaginary roots. As the development of calculus and its enormous applications are well known, we will not discuss much
about it.
Earlier, he was in TIFR, Bangalore. His research interests include partial differential equations, homogenization, controllability
and control problems, analysis, etc. 相似文献

隐性衔接语篇连贯指的是不含显性衔接手段,如替代,省略,重复等,实现语义连贯的语篇。作为一种特殊的语言现象,隐性衔接语篇也是一种心理上的表征,是人类对认识世界的经验总结从语言上的反应。理想化认识模型（ICM）是人们在特定的文化背景中对某领域中的经验和知识所作出的抽象的、统一的、理想化的理解,它具有关联性、选择性、典型性,体验性等特征。正是因为人类对认知世界的体验,形成各种认知模型（CM）,而认知模型（CM）稳定而有规律,具有典型性特征。在认知过程中,各种认知模型（CM）之间的互相关联与相互选择,正好为人们解读隐性衔接语篇提供了认知上的新视角。 相似文献

Nanotechnology has been touted as the next ‘industrial revolution’ of our modern age. In order for successful research, development, and social discourses to take place in this field, education research is needed to inform the development of standards, course development, and workforce preparation. In addition, there is a growing need to educate citizens and students about risks, benefits, and social and ethical issues related to nanotechnology. This position paper describes the advancements that have been made in nanoscale science and nanotechnology, and the challenges that exist to educate students and the public about critical nanoscience concepts. This paper reviews the current research on nanotechnology education including curricula, educational programs, informal education, and teacher education. Furthermore, the unique risks, benefits and ethics of these unusual technological applications are described in relation to nanoeducation goals. Finally, we outline needed future research in the areas of nanoscience content, standards and curricula, nanoscience pedagogy, teacher education, and the risks, benefits, and social and ethical dimensions for education in this emerging field. 相似文献
