环境保护问题是人类面临的三大问题之一．因为环境跟人类生活有着十分密切的关系．它关系到人类的生存,关系到国计民生。环境保护问题已越来越为世界各国所重视。在我国,环境污染的治理和环境的保护已列入基本国策。但由于我国对环境的治理起步较晚,法制上还不十分健全,人民群众的环境意识和环保观念也很淡簿,就目前的形势而言,环境污染是非常严峻的,所以加强环保教育已显得特别重要． 相似文献

近年来,我国经济的加速发展导致了环境污染问题不断加剧。为了人类共同的家园,保护环境已成为每一个公民应尽的责任和义务。化学与环境有着密切的关系,如何在化学教学中帮助学生树立良好的环境保护意识,是每一位化学教师义不容辞的责任。本文从四个方面论述了这一问题：以学生手中的化学教材为载体,教师精心设计问题,通过问题的解决．帮助学生树立良好的环境保护意识;鼓励学生充分利用课余时间,在报刊、杂志、互联网上收集有关环境现状的资料,激发他们对环境保护的欲望：充分利用化学实践活动,让学生参与到环境保护的行列中,加强学生的环境保护意识;设计习题练习．巩固教育成果。 相似文献

环境保护问题是人类面临的三大问题(人口、能源、环境)之一。因为环境是跟人类生活有着十分密切的关系，地球只有一个．地球环境的好坏直接关系到人类能不能继续生存下去的问题。环境保护问题已越来越为世界各国所重视，环境意识已成为当代人类文化素质的重要组成部分，并成为衡量一个国家。一个民族乃至一个人的文明程度的重要标准。联合国教科文组织已把生态教育列为主要工作．并推行了一系列环境教育计划，将1990—1999年作为“环境教育十年”。 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献
