2、01 年第 6 期啄木鸟杂志。作者以令人触目惊心的大量事实,展示了我国地质灾害所造成的严重后果,呼吁每个公民善待自己,善待家园。名师精编优秀教案三、结构分析按新闻的结构划分本文层次:导语:作者以大量的事实和数据,展示了我国地质灾害的严重后果,点出“人祸”是主要原因。第一部节(标题1):“珊瑚礁不仅仅是美丽的”,主要披露了海南省文昌市80%珊瑚礁海岸带遭到严重破坏的情况。第二部分(标题2):“大山是知恩图报的”,以北京延庆县的两个山村的不同遭遇为例,说明注重自然生态环境保护的重要性。第三部分(标题3):“裸露的土地就像裸体的我们自己”,揭示了垦草种粮、过度放牧造成内蒙古草原大面积沙漠化,生态日益
3、严重。结语:作者再次呼吁“善待家园,就是善待自己”,“防治地质灾害是每位公民义不容辞的责任”。首尾呼应。四、整体感知(加强对事例的理解,体会作者的情感)自读课文,练习复述三则事例。“珊瑚礁不仅仅是美丽的”,主要披露的是海南省文昌市80%的珊瑚礁遭受严重破坏的情况。其原因一是挖珊瑚礁当作旅游纪念品卖钱,另一个更主要的原因是以珊瑚礁为原料烧石灰,个人的腰包鼓起来了,而“海岸线的天然屏障就这样被破坏了”,要想恢复“至少要等上一千年”。“大山是知恩图报的”,以北京延庆县两个山村的不同遭遇为例,说明了注重自然生态环境保护的重要性。地质条件相当恶劣的东三岔村,由于村民对大山进行了综合治理,抵抗住了特大暴雨
4、的袭击,如今像一个景色宜人的森林公园;而相距仅八公里的松树沟村却在同一场大暴雨的袭击下诱发了泥石流,成了碎石的世界,失去了自己的家园。“裸露的土地就像裸体的我们自己”,揭示了垦草种粮、过度放牧造成内蒙古草原大面积沙漠化,生态危机日益严重。五、问题探究1请同学们思考:三则事例反映了什么样的普遍社会现实?明确:作者从三个不同的角度,说明了一个同样的事实:人祸已成为我国地质灾害最主要的原因。2作者想通过这篇文章表达怎样的中心?明确:文章以一件件具体的、典型的、无可辩驳的事例,说明了我国地质灾害的严重性,真是文档编码:CF6Z1H1N9Q8 HS2S8X3H4R9 ZX10N7W7X3K6文档编码:C
