高中“对应关系说”函数概念是在初中“变量说”函数概念的基础之上的进一步抽象,为下一步研究函数的性质打下基础.教学中要把握函数概念的本质,帮助学生理解“对应关系说”函数概念引入的必要性.教师要在熟读课标、研透教材的基础上,... 高中“对应关系说”函数概念是在初中“变量说”函数概念的基础之上的进一步抽象,为下一步研究函数的性质打下基础.教学中要把握函数概念的本质,帮助学生理解“对应关系说”函数概念引入的必要性.教师要在熟读课标、研透教材的基础上,巧妙地在知识点间搭建容易让学生攀爬的阶梯,引导学生通过思考,从分析单个实例上升到概括一类实例具有的共同特征,理解函数概念的内涵,得到研究方法的系统训练,培养数学思维能力,发展独立解决问题的能力. 展开更多

Numerous legends are known in Eurasia, in which one or more hunters are trying to get a stag, and then the hunters will find a new homeland, or establish a new cathedral at the location where the deer appeared earlier. According to the structure of the legend, the Eastern legend type is more ancient. In its most archaic version the sole hero spots a doe, who later turns out to be the daughter of a king, later marrying the hero and then they found a new homeland where his people may reproduce. This totemic tradition of the origins can he seen in the Hungarian myths of origin, as well as in the oral ritual texts related to wedding ceremonies which connect Central Eurasia with Europe through the Hun origin myths. The doe appearing in the Eastern Legends is the symbol of the Sun and the ancestress of the culture hero's nation. And this symbolic role descends to the cultural heritage of the Christian era later in the person of Virgin Mary. The aim of the paper is to find whether there are any correspondences between the two branches and if there are, the sort is to be determined; furthermore, the purposes of the Hungarian legends are to be sought out about the Miracle Stag in possible relation to the deer legends on the two continents linked together by the Eurasian steppes. 展开更多
