材料四:印度提倡“只生一个好”——鼓励三人小家庭 生男生女都一样材料五:印度尼西亚《人口发展与幸福家庭法》材料六:我国基本国策 计划生育(小结)通过对以上材料的分析我们可以得出这样的结论,不同的国家应该采取不同的人口政策,对与发达国家来说人口增长缓慢,应采取鼓励生育,吸引移民的措施;发展中国家人口增长较快,实行控制人口的政策已经迫在眉睫。不论是发达国家还是发展中国家共同的目标就是实现环境人口和社会经济的协调发展。【课堂小结】这节课我们主要学习了人口的自然增长,影响人口自然增长的因素有哪些?(人口的自然增长率和人口的基数)世界人口的数量在不同的历史时期表现出不同的特征,同一历史时期的不同地区,人口数量的增长又有不同的特点。面对不同的人口形势,各国应采取不同的人口政策。
过渡:下面我们从时间角度分析世界人口数量变化的趋势是怎样的呢?为什么会这样呢?板书:1、人口自然增长的时间变化(引导学生读课本图1.2和图1.3,让学生分析)教师首先让学生说出阅读地理曲线统计图的一般步骤和方法,然后总结归纳:1、 读图名。2、 读各个坐标分别表示什么变量(两图横坐标均表示时间,纵坐标均为相应时期人口数)。3、 判读图形变化特征(两图中曲线曲率的变化反映对应时段内人口自然增长率的大小)。4、 思考变量之间的因果关系(两图均反映不同历史时期世界人口数量增长的不同特点)。问:世界人口数量变化的总趋势是什么?(让学生结合课本P2读图思考题,分析回答同时让学生阅读课本图1.3,在图1.2中找出图1.3所在的时段,指导学生自学P3第一段,让学生分析近100年全球人口快速增长的原因。最后师生共同归纳总结,填写下表。)
经济因素对人口迁移是主要的,经常起作用的因素,是人口迁移的基本动因。通常情况下,经济发展水平的差异决定着人们迁移的方向,人们迁移是为了追求更好的就业机会和更高的经济收入。经济发展水平高的地区往往成为人口迁入地,人口的迁移量取决于迁入地对劳动力的需求状况和迁出地人口相对过剩的状况。师:20世纪80年代深圳、珠海等地设立了经济特区’吸I了大量的人口迁入。这又说明了什么问题? (生回答,师总结)从宏观上看,经济布局也会造成大量的人口迁移。说明经济越发达,对人口的吸引力(即拉力)越大。经济发展水平、规模和速度决定着人口迁移的流向、流量和流速。师:交通和通讯又如何影响着人口的迁移呢?生:交通和通讯的发展,缩小了地区之间的距离,促进了人口迁移。
1.促使美国成为一个移民国家的因素是:①美洲属于未开发的新大陆,需要大量的劳动力;②欧洲失业工人和破产农民增加,人们为了追求更好的经济待遇迁往美洲;③新航线的开辟为人们顺利迁移扫除了障碍;④殖民扩张是人口迁移的促进因素,加快了人口迁移的过程。导致美国人口在本土范围内频繁迁移的原因,归纳起来有:第一次人口迁移是战争因素,第二次是城市化;第三次是自然环境、经济环境的变化;第四次是经济格局的变化,即西部和南部新资源的发现和新兴工业的发展。2.我国古代的人口迁移,深受统治者及其行政力量的束缚。封建帝王为了加强本国的经济和军事实力,对人口迁移严加控制。只有当战乱发生的时候,这种控制才得到削弱,人们为了躲避战乱,寻找安定的生活环境,不得不进行大规模的迁移。我国近几十年的人口迁移主要是由生产资料和劳动力数量上的地区分布不平衡造成的,是经济因素在起主导作用,与古代的人口迁移截然不同。
师:在保证现代人生活幸福,同时又不降低未来人生存质量的前提下,一个地区、一个国家,乃至整个地球到底适合养活多少人呢?为了回答这个问题,科学家在环境人口容量的基础上,又提出了人口合理容量的概念。板书:(一)人口的合理容量1、概念:是指按照合理的生活方式,保障健康的生活水平,同时又不妨碍未来人口生活质量的前提下,一个国家或地区最适宜的人口数量。2、特点:理想的、难以确定精确数值的“虚数”3、概念提出的意义:对于制定一个地区或一个国家的人口战略和人口政策有着重要的意义,进而影响区域的经济社会发展战略。(二)正确处理人类在世界各地消除贫困与保持人口的合理容量的关系本部分采取教师提出问题——学生讨论——阅读教材——学生进一步探讨——学生代表发言——学生补充——教师总结的程序进行:(1)请同学们结合日常生活实例和教材分析说明人类要在世界各地消除贫困并保持人口的合理容量任务的艰巨性?
生1:公平性原则——同代人之间要公平,代际之间、人类与其他生物种群之间、不同国家与地区之间也要公平。生2:持续性原则——地球的承载力是有限的,人类的经济活动和社会发展必须保持在资源和环境的承载力之内。生3:共同性原则——发展经济和保护环境是全世界各国共同的任务,需要各国的共同参与。同时,地球作为一个整体,地区性问题往往会变为全球性问题,所以地区的决策和行动,应有助于实现全球整体的协调。活动与探究:2·阅读下面一篇新闻报道,你认为“给蛇让道”有没有必要?答:有必要·人类在森林区内修筑公路,已经侵占和破坏了蛇的生存环境,如果再不对蛇的迁移进行保护,蛇数量的减少以至灭绝将不可避免。这种做法体现了可持续发展的公平性原则和共同性原则。3·用可持续发展的观念作为衡量标准,对下列观点作出评价。(1)人类有义务保护地球上所有的物种,人类的发展不应该危及其他物种的生存。答:正确。符合可持续发展的公平性原则。
★本课小结:通过学习,我们可以看出鸦片战争后,随着外国资本主义经济的入侵,中国近代经济结构发生了重大变动:自然经济逐渐瓦解,商品经济日益发展,中国民族资本主义产生,中国社会经济结构正经历着一场史无前例的大转型。清政府内部的洋务派为了维护封建统治,掀起了洋务运动。这次运动在促使本国封建经济瓦解的同时,对民族资本主义的产生起了诱导作用。受外商企业和洋务运动的诱导,十九世纪六七十年代民族资本主义在中国产生,由于受外国资本与本国封建势力的压制,举步维艰;下节课,我们将关注中国资本主义的曲折发展。★问题解答⊙【学思之窗】你认为郑观应的批评是否有道理?为什么?参考答案:(1)有道理。(2)原因:①郑观应认识到了社会制度层面的“体”与科学技术层面的“用”之间不是等同的关系。

①自然经济的逐步解体;(西方列强的侵略)在给中华民族带来沉重灾难的同时,也不断地冲击着中国社会的生产方式和思想观念,分解着中国自给自足的封建经济。客观为民族工业的兴起和发展提供了某些条件和可能。②清末至民国政府鼓励兴办实业;(历届政府的扶植)由于时代潮流的冲击和巩固统治的需要,清末至民国历届政府都鼓励兴办实业。③反帝爱国运动的推动。(反帝爱国运动的推动)中国人民反帝爱国热情不断高涨,使“实业救国”具有日益广泛的社会基础,特别是抵制洋货、提倡国货运动不断兴起,有力推动民族工业的发展④实业家自强不息的爱国精神。(实业家们自强不息的爱国精神)是支撑民族工业曲折发展的动力和力量的源泉。本课小结:扼要回顾民族工业的曲折发展历程,进而启导学生探究影响其发展的因素,最后分析其历史地位。中国民族资本主义的发展在中国近代史上具有重要的历史地位,对近代中国历史和社会的发展产生了重大影响。
师:对。具体说一说沼气池在这个系统中为什么居于核心纽带地位。生:因为沼气池充分利用了生产过程的废料,实现了清洁生产,减少了浪费和污染,而且很好地实现了生态循环。师:不错!留民营生态农业的实质就是:地尽其利,物尽其用,最大限度地循环利用资源和消除环境污染,达到节约、高效的目的,真正实现了生态效益、经济效益、社会效益三方面的高度统一,实现了可持续发展。师:实施可持续发展战略必须依靠公众的支持和参与,我们每一个人都应该从自身做起,那我们可以在日常生活中可以采取哪些有益于可持续发展的行动? 生1:节约粮食、爱惜粮食。生2:不乱扔垃圾,垃圾分类回收。生3:不开“无人灯”。生4:节约用电、用水。生5:减少空调的使用,在冬夏季分别降低、提高空调温度的设置。
世界观、人生观、价值观是人们文化素养的核心和标志。一个人的世界观、人生观、价值观是在长期的生活和学习过程中形成的,是各种文化因素交互影响的结果。世界观、人生观、价值观一经形成,就具有确定的方向性,对人的综合素质和终身发展产生深远而持久的影响。◇课堂探究:(1)你能补充一两个定居海外的华裔在生活方式和习俗方面仍然表现出受我们民族文化影响的事例吗?(2)能否谈谈你阅读这段话时的感悟,并用自己的理解说明文化对人的影响力?◇探究提示:(1)启发同学们搜集材料,了解历史上或现实生活中海外华侨的生活方式受中华民族文化影响的具体事例。(2)通过阅读这段话,可以感受到,一段丰富的人生经历、一份令人心动的情感、一种远大的理想、一种催人奋进的力量,会深深地影响着人的发展。
另一方面,文化素质影响公民政治权利的行使。随着民主和法制建设的发展,人们为了参与政治生活,需要更高的文化素养。文化水平提高了,人们受到的教育、接受的信息就越多,活动的领域就越广,民主法制和权利意识就越强,这些都会影响人们的民主素质和民主水平,使人们更好地进行政治参与,行使民主权利。(2)文化与国际政治相互交融,成为当代国际政治斗争的重要内容。随着世界多极化的发展,奉行霸权主义的国家,借助文化渗透的方式,竭力推销自己的价值观念,企图削弱和取代别国的民族文化,以推行强权政治。这使世界范围内反对文化霸权主义的斗争,成为当代国际政治斗争的重要内容。文化已经成为进行政治斗争、国际斗争的重要形式之一。对文化市场的争夺不仅仅是争夺票房价值、争夺经济效益,更主要的是对受众对象的争夺,对受众注意力这种特殊的稀缺资源的占有,以及在此基础上对舆论的控制与引导。因此,失去文化市场就意味着失去政治优势,意味着政治影响力的边缘化乃至萎缩或丧失。这一点,从目前世界正在进行的空前规模的“文化战争”,可以看得非常清楚。
