上接9期溯源围际中学生数学竞赛的历史,最先举办的是匈亚利,匈亚利数学物理学会于1894年决定:每年10月为中学生举办一次全国性数学竞赛.除了两次世界大战和匈亚利事件而中断了几次之外,其余每年10月都在按时进行中学生数学竞赛,直延续全今.而最早用"数学奥林匹克"名字命名的中学生数学竞赛,则始于前苏联,前苏联于1934年与1935年分别在列宁格勒和莫斯科举办了中学生数学奥林匹克竞赛.到了1959年,罗马尼业数学物理学会向东欧七罔发出参赛邀请函,在布拉索大举办了第1届阳际数学奥林匹克!由此拉开了中学生国际数学奥林匹克竞赛之序幕……,至2012年.已成功举办 相似文献

数学竞赛是一项风行世界的智力竞技活动。近代的数学竞赛是从1894年开始的。这一年,匈牙利首次举行了数学竞赛。自此以后,举行数学竞赛的国家越来越多。1902年,罗马尼亚首次举行了数学竞赛。1934年,苏联首次举行了“数学奥林匹克”。此后,1949年保加利亚,1950年波兰,1951年捷克斯洛伐克等国也先后举行了数学竞赛。在此基础上,1959年罗马尼亚数理学会向东欧七国倡仪,于7月22日至23日在布加勒斯特举办了第一届“国际数学奥林匹克”(InternationalMathematicalOlympiad,简称IMO)。这是世界上最早举办的国际性的数学竞赛。自此以后,每年举行… 相似文献

1894年,匈牙利最早举办了中学生数学竞赛,从此,拉开了国际数学奥林匹克竞赛的序幕。 20世纪50年代,数学竞赛大大兴起。据统计,当时举办全国性数学竞赛的国家有中国、美国、德国、加拿大、澳大利亚等20几个国家。由于数学竞赛与体育比赛在精神上有相通之处,所以大多数国家的数学竞赛都叫数学奥林匹克;并且也像奥运会一样,从1959年起开始有了“国际数学奥林匹克”(简称IMO)。国际数学奥林匹克起先只是东欧几个国家轮流做东举办,并没有多少国际性,直到20世纪60年代末才渐渐地扩大到西方自家。现在先后参加过的国家一共有33个。现在的国际数学奥林匹克竞赛仍然是轮流做东,没有固定的组织与章程,只是每年都由参加国各选举一人,组成临时委员会,东道国代表任主席。试题在各国提出的题目中挑选,每次6题,分两个上午完成,每次4个小时,总分40分。起初几届的试题难度不大,但70年代以后明显地难了。由于中学数学竞赛的组织成功,这股风后来刮到了小学和大学里,数学奥林匹克竞赛成为选拔优秀数学人才、提高教学水平的有效途径。 (摘自《小学生学习指导》2001年第1—2期) 相似文献

我国中学教学竞赛活动起始于1986年.经过四十多年的发展,数学奥林匹克竞赛活动已经被广泛地每年在全国各省市教育所属部门的中学举行;被参加的学生由中学生发展到小学生.由全国初中、高中数学联赛发展到各种不同的形式竞赛.受数学奥林匹克活动的影响,其它学科也相继举办了奥林匹克竞赛活动.奥林匹克活动已经远远超出了一门学科竞赛的意义,它已经在竞赛的基础上逐渐形成了自己特有的人才培养模式;形成了一套较为完整的竞赛考试、评估机制.通过举办全国初中数学竞赛活动,将有力推动我国中学生数学能力的大力提高与发展;更加能尽早、及时地培养… 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

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

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

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 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

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
