低年级的学生对水有一定的认识、了解，但是用简短、准确的语言来描述却有一定难度。所以在第二课时，我采用以读代讲法进一步引导学生深入理解并有感情地朗读课文。

根据各段特点，品读方法各有不同：第一段抓住云的颜色和形态，引导学生读出云的美丽和多变。在观看图片时，鼓励学生运用平时积累的好词好句描绘多彩的云朵，结合相关谚语培养学生留心身边科学现象的习惯；

二、精读课文，指导朗读

Word word is the foundation of Chinese study, the feeling of ” of “ dinky minimum is experienced in recite, compare “ float ” and “ to float of ” different.
1、首先学习第一段，先让学生自由朗读课文，找出描写水变成云的句子，教师边范读边勾画需要理解的重点词语，划斜线提示学生注意长句的停顿和连读。字词是语文学习的基础，在朗读中体会“极小极小”的感觉，比较“飘浮”与“漂浮”的不同。
Enjoy white cloud picture, conversation seeing a picture is the first paragraph training key. Show a lot of pattern the Yun Duo picture of each different, it is good to guide a student to use has learned good word sentence a plan that him description likes most, follow a type in the text, occasionally occasionally with “ ……” says …… sentence, inspire student imagination, development language conveys ability.
欣赏白云图片，看图说话是第一段的训练重点。出示许多形态各异的云朵图片，引导学生运用学过的好词好句描述自己最喜欢的一幅图，并仿照课文中的句式，用“有时候……有时候……”说句子，启发学生想象力，发展语言表达能力。
Demonstrate blue sky white cloud, cloudy, alpenglow, afterglow next 4 kinds of different view, the beauty that comprehends cloud, changeful. Combine proverbial “ alpenglow not to go out, ” of afterglow travel a thousand li guides a student to pay close attention to the natural phenomenon beside more, know the life better. Carry the picture of these 4 different color, the sentential back of the beautiful dress of cloud of the depict in encouraging student general text comes down.
接下来演示蓝天白云、乌云密布、朝霞、晚霞四种不同景致，感悟云彩的美丽、多变。结合谚语“朝霞不出门，晚霞行千里”引导学生多关注身边的自然现象，更好地了解生活。通过这四幅不同颜色的图片，鼓励学生将课文中描写云的漂亮衣服的句子背下来。
2, water baby besides can change the cloud, what to still meet change? The 2nd paragraph study is next medium, I make a student free read a text first, find the other change pattern of water. The “ mist, dew, frost, picture that puts ” on the ice is shown on this foundation, enhance the perceptual knowledge that water can change.
2、水娃娃除了会变云，还会哪些变化呢？接下来第二段的学习中，我先让学生自由读课文，找到水的其他变化形态。在此基础上展示“雾、露、霜、冰”的图片，增强水会变的感性认识。
The 2nd paragraph of key is the accuracy that lets a student experience a language, I use the means of the fill a vacancy that choose a word to break through key of this one education. Show 3 sentences in the text first, let a student choose the most appropriate term, delimit with hand comparing “ falls, dozen, wave the different pattern of ” , experience the different feeling of weight speed. The student experiences personally between little hand rise and fall, understand the accurate, figure of the language better, develop language sense.
第二段重点是让学生体会语言的准确性，我采用选字填空的方式突破这一教学重点。先出示课文中的三个句子，让学生选择最恰当的词语，并用手比划“落、打、飘”的不同样子，体会轻重快慢的不同感觉。学生在小手起落之间亲自体验，更好地理解语言的准确、形象，培养语感。
3, the 3rd paragraph of concise and comprehensive, the language is beautiful. Pedagogic dub in background music model in reading a text to bring the student the situation that travels into water baby, the edge listens to want by the side of: What place does water baby have been to? The video picture that makes student appreciation dynamic next and water child travel together, the student lets see a graph imagine water baby “ sleeps when the Chi Shui that admires “ calm, slowly brook, Jiang He that gallop, surfy sea ” , take a walk, run, dance sing the appearance of ” . Writing on blackboard of the have the aid of on the basis that understands in the imagination, with the air with beautiful move guidance recites the 3rd paragraph.
3、第三段言简意赅，语言优美。教师配乐范读课文将学生带入水娃娃旅行的情境中，边听边想：水娃娃去过哪些地方？接下来让学生欣赏动态的视频图片和水娃娃一起去旅游，欣赏“平静的池水、缓缓的小溪、奔腾的江河、波涛汹涌的大海”时让学生看图想象水娃娃“睡觉、散步、奔跑、跳舞唱歌”的样子。在想象理解的基础上借助板书、和着优美的旋律指导背诵第三段。
Before learning 3 paragraphs hind brief summary of combinative writing on blackboard: Water becomes Yun Piao float to be in sky, become rain, hail, snow to fall down again. Water is ordinary in existence and pond, inpour brook, collect Jiang He, flow into the sea. Alleged “ alls things tends in one direction ” , form the concept that boiler circulation does not cease. The teacher is timely brief summary, conduce to a student cognitive to the whole of the text.
学完前三段后结合板书小结：水变成云飘浮在空中，又变成雨、雹子、雪落下来。水平常存在与池子里，流进小溪，汇入江河，流入大海。所谓“百川归海”，形成水循环不息的概念。教师适时小结，有助于学生对课文的整体认知。
4, water of the 4th paragraph of main description and the connection that the mankind lives. This paragraph of key is talking at training a student, connection life experiences the good work that water baby has done for people, bad thing actually. Make a student free read a text first, water baby searching in article is what disposition after all. Describe gentle water baby and petulant water child to had done what business respectively, pass a tax next demonstrate “ hydroelectric station, irrigate ” of calamity of eruptive, snow gives farm, flood the student's intuitionistic feeling. Can let a student talk, besides these, still had done what good work for the mankind in the water in the life, pedagogic help student is Baconian: Our life leaves not boiled water, manufacturing work also leaves not boiled water! Water baby did so much business for people, what mood is it? What appearance should be when it gets angry? Guide a student to act gentle the water baby with termagancy, recite understanding water to had done a lot of favours to bring a lot of disaster again for the mankind through contrast, permeate ground of one divides into two from this the affection manner viewpoint of value of thing of comprehensive look upon.
4、第四段主要描述水与人类生活的联系。这一段重点在于训练学生说话，联系生活实际体会水娃娃为人们做过的好事、坏事。先让学生自由读课文，在文中找一找水娃娃到底是什么脾气。分别描述温和的水娃娃和暴躁的水娃娃做过哪些事情，然后通过课件演示“水电站、灌溉农田、洪水暴发、雪灾”给学生直观的感受。可以让学生谈一谈，除了这些，在生活中水还为人类做过哪些好事，教师帮助学生归纳：我们的生活离不开水，生产劳动也离不开水！水娃娃为人们做了这么多事情，它是什么心情？当它发脾气时又是什么样子？引导学生扮演温和与暴躁的水娃娃，通过对比朗读理解水为人类做过许多好事又带来了许多灾难，由此渗透一分为二地全面看待事物的情感态度价值观。
3, extend outspread
三、拓展延伸
Present a commonweal advertisement and western land is short of the picture with weather-shack water, teach a student to realise: Actually China is a country that drought lacks water, be in especially western area. If do not cherish water natural resources, draw on meeting occurrence advertisement in that way the tear that on —— earth last water is us. Allow student communication finally how should we get along with water baby, permeate managing the viewpoint of value that uses water.
呈现一则公益广告和西部土地缺水干裂的图片，教育学生认识到：其实中国是个干旱缺水的国家，尤其在西部地区。如果不珍惜水资源，就会出现广告上画得那样——地球上最后一滴水就是我们的眼泪。最后让学生交流我们应该怎样和水娃娃相处，渗透节约用水的价值观。
