进入21世纪,干旱、水体污染等自然灾害和人为突发性事件频发,而宜春地区各城镇饮用水水源及备用水源以湖、河、水库等地表水体为主,这种裸露和开放式的地表水体易遭受污染,在极端干旱季节可能造成人畜用水困难。为了保障在特殊情况下的... 进入21世纪,干旱、水体污染等自然灾害和人为突发性事件频发,而宜春地区各城镇饮用水水源及备用水源以湖、河、水库等地表水体为主,这种裸露和开放式的地表水体易遭受污染,在极端干旱季节可能造成人畜用水困难。为了保障在特殊情况下的正常用水,使用地下水则成为最优选择。因为地下水具有土壤天然防污屏障,不易被污染,水质稳定且良好,供水保障高等优势。通过对宜春地区相关资料的收集,梳理出了宜春地区地下水赋存特征,并结合当地地质条件总结出了2种地下水找水模式。 展开更多

In primary school mathematics teaching, mathematics teachers should guide students to discover, think, solve, reflect on the problem, so as to cultivate students' ability to solve problems, improve students' ability to learn mathematics. How to guide students to find problems and answer them from various angles in class is the main problem for teachers to explain knowledge and enhance students' accomplishment. Primary school mathematics is an important subject to cultivate students' thinking ability, spatial concept, number sense, operation ability and other qualities, teachers should be committed to strengthening students' ability to solve problems, improve their mathematical learning efficiency, so that students can achieve all-round development in mathematics class. This paper explores the importance of developing problem-solving ability in primary school mathematics teaching, analyzes the problems existing in the training process, and puts forward corresponding optimization measures. We should carry out questioning teaching, change teaching mode, carry out group cooperation, establish reflective consciousness, and strengthen practice. 展开更多
