教学设计：本课教学内容为为人教版选修8第三单元阅读课The Problem of the Snakes，讲述的是一女孩儿如何通过多次尝试，最后成功地把在他母亲家院子里安家的一窝蛇捉住并放归大自然的，他的捕蛇技术也申请了发明专利；文章也提到了申请专利的标准。
文章篇幅较长，内容与学生生活实际不是特别密切。
基于上述分析，本节课的教学设计思路从体裁，思维培养，语言和文本处理四个层面入手。
1．从体裁层面：此文章为故事性的科技文，故事性较强，因此时间线索贯穿始终，因此文章梳理时抓住这一主线，将主要信息进行提炼和理解，让学生对前因后果有个纵向的掌握；而且文章主题升华围绕科技对人类的影响进行适度的引导。
2．从思维培养层面：既然是科技文，因此文章的逻辑性和条理性极强。
所以在处理文章内容时，将充分利用各种thinking map 即思维导图归纳，整理和输出主要信息，以帮助学生建立和运用一些初级的逻辑思维。
3．从语言层面：本课文的语言本身不是很难，但是作为科技文，其语言表达准确，逻辑严谨，因此将通过对部分重点词句的解读，让学生感知这种文体特征。
4．从文本处理层面：此文本篇幅较长，就一节课无法面面俱到，因此根据本节课的核心任务或者out-put的需要，着重处理文章前半段，即捕蛇的环节，申请专利环节有涉及，但是不强调，以做到重点突出。
二．教学目标1．通过Thinking map 的方法，进行文章信息的解读，梳理以及输出；2．对部分词句进行重点解读，学习（故事性）科技文的逻辑和语言特征。
3．联系生活中的小发明和人类史上伟大的发明家，感知科技对人类生活的影响。

新课标人教版选修8-U n i t3-课文The Problem Of The SnakesWhen I called up my mother in the countryside on the telephone she was very upset. "There are some snakes in our courtyard," she told me. "Snakes come near the house now and then, and they seem to have made their home here, not far from the walnut tree. Can you get rid of them please?" I felt very proud. Here was a chance for .me to distinguish myself by inventing something merciful that would catch snakes but not harm them. I knew my parents would not like me to hurt these living creatures!The first thing I did was to see if there were any products that mightA new approach was clearly needed. I set about researching the habits of snakes to find the easiest way to trap them. Luckily these reptiles are small and that made the solution easier.Prepared with some research findings, I decided on three possible approaches: firstly, removing their habitat; secondly, attracting them into a trap using male or female perfume or food; and thirdly cooling them so that they would become sleepy and could be easily caught. I decided to use the last one. I bought an ice-cream maker which was made of stainless steel. Between the outside and the inside walls of the bowl there is some jelly, which freezes when cooled. I put the bowl into the fridge and waited for 24 hours. At the same time I prepared some ice-cubes.The next morning I got up early before the sun was hot. I placed the frozen bowl over the snakes' habitat and the ice-cubes on top of the bowl to keep it cool. Finally I covered the whole thing with a large bucket. Then I waited. After two hours I removed the bucket and the bowl. The snakes were less active but they were still too fast for me. They abruptly disappeared into a convenient hole in the wall. So I had to adjust my plan.For the second attempt I froze the bowl and the ice-cubes again but placed them over the snakes' habitat in the evening, as the temperature was starting to cool. Then as before, I covered the bowl with the bucket and left everything overnight. Early the next morning I returned to see the result. This time with great caution I bent down to examine the snakes and I found them very sleepy. But once picked up, they tried to bite me. As they were poisonous snakes, I clearly needed to improve my design again.My third attempt repeated the second procedure. The next morning I carried in my hand a small net used for catching fish. This was in the expectation that the snakes would bite again. But monitored carefully, the snakes proved to be no trouble and all went according to plan. I collected the passive snakes and the next day we merrily released them all back into the wild.Pressed by my friends and relations, I decided to seize the opportunity to get recognition for my successful idea by sending myinvention to the patent office. Only after you have had that recognition can you say that you are truly an inventor. The criteria are so strict that it is difficult to get new ideas accepted unless they are truly novel. In addition, no invention will get a patent if it is:a discoverya scientific idea or mathematical modelliterature or arta game or a businessa computer programmea new animal or plant varietyNor will you receive a patent until a search has been made to find out that your product really is different from everyone else's. There are a large number of patent examiners, too, whose only job is to examine whether your claim is valid or not. If it passes all the tests, your application for a patent will be published 18 months from the date you apply. So I have filled in the form and filed my patent application with the Patent Office. Now it's a matter of waiting and hoping. You'll know if I succeed by the size of my bank balance! Wish me luck!ALEXANDER GRAHAM BELLAlexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA. His mother was almost entirely deaf, so Alexander became interested in helping deaf people communicate and in deaf education. This interest led him to invent the microphone. He found that by pressing his lips against his mother's forehead, he could make his mother understand what he was saying.He believed that one should always be curious and his most famous saying was:"Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never seen before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought."It was this exploring around problems and his dynamic spirit that led to his most famous invention - the telephone in 1876. Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. This original telegraph sent a message over distances using Morse code (a series of dots tapped out along a wire in a particular order). But only one message could go at a time. Bell wanted to improve it so that it could send several messages at the same time. He designed a machine that would separate different sound waves and allow differentconversations to be held at the same time. But he found the problem difficult to solve. One day as he was experimenting with one end of a straw joined to a deaf man's ear drum and the other to a piece of smoked glass, Bell noticed that when he spoke into the ear, the straw drew sound waves on the glass. Suddenly he had a flash of inspiration. If sound waves could be reproduced in a moving electrical current, they could be sent along a wire. In searching to improve the telegraph, Bell had invented the first telephone!Bell was fully aware of the importance of his invention and wrote to his father:"The day is coming when telegraph wires will be laid on to houses just like water or gas – and friends will talk to each other without leaving home."The patent was given in 1876, but it was not until five days later that Bell sent his first telephone message to his assistant Watson. The words have now become famous:"Mr Watson - come here - I want to see you."Alexander Graham Bell was not a man to rest and he interested himself in many other areas of invention. He experimented with helicopter designs and flying machines. While searching for a kite strongenough to carry a man into the air, Bell experimented putting triangles together and discovered the tetrahedron shape. Being very stable, it has proved invaluable in the design of bridges.Bell was an inventor all his life. He made his first invention at eleven and his last at seventy- five. Although he is most often associated with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybody's life.。

人教版第八模块第三单元说课稿
尊敬的评委老师，大家好:我是XX。
今天我说课的的内容是高中课标实验教材人教版，第8模块第三单元“Inventors and inventions”的阅读课题目为“The problem of the snakes”这是一篇记叙发明过程的课文。
主要内容为，小作者从发现问题—做研究—想方案—多次验证方案--- 获得成功并申请发明专利的过程。
从“为什么学”入手，我对教材和学情进行了充分的研读和分析，从而制订了本节课的教学目标，教学重难点，并围绕教学目标以及重难点，将多种教法进行整合，进一步设计了本节课的教学过程。
在最后，通过对本节课进行反思，做出教学反思报告。
一：首先说教材分析，1首先说对教材的理解，教材是一种传递教学内容的手段，它只是一种材料。
所以在教学过程中充分利用教材是必须的，但却不能被教材牵着走，过度的依赖教材。
在利用教材的时候要从学生的实际情况出发，吃透教材，帮助学生走进教材再跳出教材，获得个性的发展，从而做到创造性的利用教材。
这篇文章，虽然是一篇类似于故事的记叙文，但作者却没有运用生动而感性化的语言去描述，而是始终遵循发明的程序，严格叙述事实。
这篇文章共分为8个自然段共计715字。
主要从发明过程和专利申请两大方面展开。
文章中含有较多的生词和复杂的句型，将给学生的学习带来阻碍。
发明的细节描述，需要学生有一定的逻辑思维和空间想象能力，这将成为理解上的瓶颈。
二、学情分析在进行学习水平分析的时候，首先要确定学习者的特征。
这将很大程度上影响到学习材料、教学方法以及教学媒体等多方面的选择。
在分析学习者认知发展水平时，根据皮亚杰关于认知发展的四阶段的学说，目前在校的高二学生应处于形式运算阶段，其特征为，学生已经具备一定的假设—演绎思维和逻辑推理能力，因而在教学过程中可以将具体的事物或概念作为认识抽象事务的基础，引导学习者的思维向抽象的逻辑思维发展。
根据高中生情感发展的独立性、自主性强的这一一般特征，在教学中要加强价值观的培育，使他们逐步地建立起远景性学习动机。

精品教学教案设计| Excellent teaching plan教师学科教案[ 20–20学年度第__学期]任教学科： _____________任教年级： _____________任教老师： _____________xx市实验学校精品教学教案设计| Excellent teaching planUnit3 Inventors and inventions ----ReadingThe problem of the snakes1.整体设计思路、指导依据说明英语教学不是一个单纯的“授予 ----吸收”的过程，而是一种动态教学或活动教学，教学过程是交际活动过程。
新课标明确提出：“ 发展学生听、说、读、写的基本技能，提高初步运用英语进行交际的能力，”所以只有从组织教学活动入手，大量地进行语言实践，使英语课堂尽可能的交际化，才能有效地培养学生运用英语进行交际的能力。
而且高一学生，已经具备一定的基础知识和技能，所以本节课本节课结合本班学生的实际和潍坊3-4-5优质高效课堂，采用了“合作探究”的教学方法。
采用讨论式，引导学生主动探索，自己构建新知识；通过层层深入的题目设计，使学生的思路逐渐开阔，有利于使学生养成良好的阅读习惯，提高他们独立的阅读分析能力，也有利于培养学生分析问题和解决问题的能力，提高他们的综合交际能力。
2.教学背景分析教学内容分析：阅读是学生学习英语必须掌握的技能，其重要性不言而喻。
如何提高学生的阅读能力就成了我们每个英语教学工作者苦思冥想的问题。
当然提高学生阅读能力的方法很多，但在我们平时的教学实践中，我们应该充分利用教材，采用整体教学的方式把阅读所需的技能技巧融化在平时的教学中，乃是提高学生阅读能力的有效办法之一。
在高中英语 reading 课的教学过程中，应充分利用学生的知识，对篇章内容反复进行预测、证实，培养学生对篇章结构的分析、推断、归纳和总结的能力，通过教师精心组织教学活动，学生的思维在课堂上将能保持活跃。
