读课题，说说自己读完课题后有什么疑问。整体感知什么是纳米？什么是纳米技术？纳米技术为什么在我们身边？

本课出现了很多科学术语，默读课文圈画出文中的科学术语，并多读几遍。（课后第1题）除臭技术微观对象纳米缓释技术长度度量单位这种大小的物质纳米自清洁技术碳纳米管纳米管储氢气纳米吸波技术探测雷达波纳米技术到底是什么呢？它有什么神奇之处呢？下节课，我们一起来学习！课堂演练一、看拼音，写词语。shūcàishājūn（）（）（）（）chúchòu（）乒乓拥有杀菌除臭蔬菜jiànkāng（）健康pīngpāngyōngyǒu二、按意思写词语。1.指新鲜特别。（）2.没有能力去做，帮不上忙。（）新奇无能为力三、将下列搭配恰当的词语用线连起来。深刻的新奇的特性变化技术灵敏的上节课我们学习了生字，这节课让我们继续和作者一起走进课文，去领略纳米技术的新奇。第二课时

读了课文后，你有什么不懂的问题？提出来和同学交流。

（课后第1题）互动课堂问题1：什么是纳米技术，它到底是一门什么学问？纳米是非常非常小的长度单位，1纳米等于十亿分之一米。如果把直径为1纳米的小球放到乒乓球上，相当于把乒乓球放在地球上，可见纳米有多么小。纳米技术的研究对象一般在1纳米到100纳米之间，不仅肉眼根本看不见，就是普通的光学显微镜也无能为力。这种纳米级的物质拥有许多新奇的特性，纳米技术就是研究并利用这些特性造福人类的一门学问。纳米技术：研究1-100纳米的性质和应用的技术。列数字作比较

运用了列数字的说明方法，介绍得更明白形象些。纳米是非常非常小的长度单位，非常非常小。纳米是非常非常小的长度单位，1纳米等于十亿分之一米。比较句子

哪些句子生动地向我们介绍了纳米是非常非常小的长度单位？

如果把直径为1纳米的小球放到乒乓球上，相当于把乒乓球放在地球上，可见纳米有多么小。

运用作比较的说明方法生动地向我们介绍了纳米是非常非常小的长度单位。

无可奈何力不从心

束手无策

爱莫能助词语积累（“无能为力”的近义词）什么是纳米技术呢？这得从纳米说起。纳米是非常非常小的长度单位，1纳米等于十亿分之一米。如果把直径为1纳米的小球放到乒乓球上，相当于把乒乓球放在地球上，可见纳米有多么小。纳米技术的研究对象一般在1纳米到100纳米之间，不仅肉眼根本看不见，就是普通的光学显微镜也无能为力。这种纳米级的物质拥有许多新奇的特性，纳米技术就是研究并利用这些特性造福人类的一门学问。中心句总分

问题2：第二自然段是围绕哪句话来写的？

请同学们用上今天所学的方法：围绕一个中心句，用上不同的说明方法，介绍你身边熟悉的一种事物的特点。 小练笔

我们的生活离不开手机。今天，一种便捷的通讯工具——手机，早已悄然走进了我们的生活。手机的应用非常广泛，是我们相互联络的必不可少的手段之一。1973年4月，美国摩托罗拉公司工程技术员“马丁·库帕”发明了世界上第一部真正面向市场的手机，“马丁·库帕”从此也被称为现代“手机之父”。近年来，手机的使用量有了飞速的增长，使之成为了人们日常生活中越来越不可缺少的一部分。

为什么手机会成为我们生活中的主导呢？首先，手机可无线通话，携带方便又灵巧。它为我们与世界沟通提供了巨大的帮助。其次，手机的功能越来越多，使我们从中获取了很多乐趣，比如，上网，玩游戏，听音乐，录音、照相、发短信、视频聊天、GPS……现在的人们在生活中已经离不开手机了。问题3：纳米技术新奇的特性体现在哪里？

冰箱里如果使用一种纳米涂层，就会具有杀菌和除臭功能，能够使蔬菜保鲜期更长。纳米涂层：杀菌、除臭

有一种叫“碳纳米管”的神奇材料，比钢铁结实百倍，而且非常轻，将来我们有可能坐上“碳纳米管天梯”到太空旅行。碳纳米管：结实、轻太空天梯的理想材料碳纳米管结构示意图比较句子

有一种叫“碳纳米管”的神奇材料，比钢铁结实百倍，而且非常轻，将来我们有可能坐上“碳纳米管天梯”到太空旅行。

有一种叫“碳纳米管”的神奇材料，将来我们有坐上“碳纳米管天梯”到太空旅行。去掉红色词语再来读一读，你觉得哪个句子更好？你觉得哪个句子更好？

第一句更好一些。这些红色词语让我们感受到了说明文语言的科学性、严谨性。

在最先进的隐形战斗机上，用到一种纳米吸波材料，能够把探测雷达波吸收掉，所以雷达根本看不见它。纳米吸波材料：吸收掉探测雷达波问题4：为什么说纳米技术将给人类的生活带来深刻的变化？纳米技术改变着人类的生活。纳米技术将给人类的生活带来深刻的变化。在不远的将来，我们的衣食住行都会有纳米技术的影子。纳米技术将会使人类的生活更加美好。

纳米技术就在我们的身边。听说过EPS吗？就是汽车的汽油燃烧装置。它是应用纳米技术将汽油分子分割成纳米为单位的质子保证充分燃烧。气体燃烧完全，有助于动力提升，节约了能源，改善了环境。

“纳米技术就在我们身边”，结合课文和查找的资料，说说你的理解。（课后第2题）

纳米雨衣伞是雨伞与雨衣的结合体。纳米雨衣可由纳米雨伞转变而成，纳米雨衣又不同于一般的雨衣，因为纳米雨衣能够保证从头到脚绝对不湿。因为纳米材料，所以这雨伞能够一甩即干，雨伞转变为雨衣后，这雨衣也只需穿戴着轻轻一跳也即可全干。纳米技术可以让人们更加健康。请你结合课文内容和查找的资料，说说你
