热爱该项工作的主要原因是能帮助人们免遭火山袭击 作者的主要工作是收集 基拉韦厄火山的资料 并和其他科学家一起分析和预测火山岩浆的流速和方向 火山爆发不会造成很大的损失 因为山顶附近没有居民 但是 从山上流下的 熔岩会烧毁和埋没周围的城镇 然而 观看火山爆发是非常令人兴奋的 红色 的熔岩喷向高空 高达数百米 甚是壮观 有一次火山爆发后 作者和另外二 位科学家一道来到火山口 他们身穿白色的防护服 艰难地走近火山口 观察 沸腾的火山口中央 并采集了部分岩浆以作研究 最后 作者表述了他对自己 工作的热情 在从事这项工作 20 年后 火山对他的吸引力依然不减 Teaching goals 教学目标教学目标 1 1 Knowledge goals 知识目标 知识目标 To enable the students to learn about the powerful natural force

suggesting language teaching 暗示法 Task based language teaching 任务型教学法 Teaching procedures 教学步骤 教学步骤 Step 1 Lead in 导入导入 Purpose To get Ss to learn about volcano eruption and the disasters resulting from it 目 的 使学生了解火山爆发的过程以及其导致的灾难 T Show a piece of video which is about the volcano eruption to stimulate the Ss visually Give them two questions at the same time What do you think of volcano eruption and what can we do about it T A volcano eruption can do great damage to human beings It seems that we human beings are powerless in front of these natural forces But it can be predicted and damage can be reduced that is to say prediction is very important Who will do this kind of job and what do you think of the job Perhaps they will choose the words dangerous boring or tired to describe the volcanologist s job catch the chance to lead to the topic of the passage An Exciting Job which will make a contrast making the Ss guess the reason why the writer says his job is exciting rather than dangerous or other words Then listen and show the real reason said by the writer in the passage At last ask Ss Do you want to know more about the passage 设计理念设计理念 通过播放一段火山爆发的视频短片来刺激学生的视觉 同时提问学 生两个问题 你是怎样看待火山爆发的 我们人类能做些什么 同学们会谈 到火山爆发以及对人类造成的伤害 面对自然灾害的强大 我们人类真的无能 为力吗 由此引出预测工作的无比重要 而这项工作必须由火山学家去完成 无疑这项工作是非常危险的 但是我们文章的作者作为火山学家却认为这是一 份令人振奋的工作 此时让学生首先猜测其中原因 锻炼他们的猜测能力 然 后播放文章作者的一句话 说出真正的原因 最后问学生是否想更多地了解全 文 以此导入本课主题 完成过渡环节 Step 2 Skimming 略读略读 Purpose To get a brief understanding of the text and summarize the main idea of the text 目 的 使学生对文章有个简单的了解并且能概括出文章主旨 1 Get the students to read the passage quickly Give them several minutes to look through the whole passage Tell them to read the text silently in order to improve their reading speed and then summarize the main idea of the text 2 Get the students to read the passage again focusing on the connection between the paragraghs analyze the structure of the text A choice will be shown to help them 3 After the students can understand the structure clearly ask them to match the main idea of each paragraph with the right one 设计理念设计理念 为了培养学生略读的能力 在此设计了三个环节 首先在刚开始接 触文章时让学生学会快速浏览文章 抓住文章主旨 其次在此基础上让学生把 阅读的重点放在段落之间的关系上 以便分清篇章结构 最后就是落位每一节 的主要内容 做到对于文章的脉络很清晰地把握 Step 3 Scanning 查读查读 Purpose To get the students grasp some details in the passage which will be helpful to their understanding about the passage 目 的 让学生通过掌握一些文章细节 来锻炼他们查找细节信息的能力 同 时让这些细节帮助学生更具体的理解文章内容 1 To get the students read the passage carefully paying attention to the details Then show them some sentences asking Ss to decide whether they are true or false if there are any mistakes try to correct them 2 In order to help the students understand the passage more clearly a fill in blank exercise will be given to them which includes many details 设计理念设计理念 为了培养学生查读信息的能力 在此同样设置了两个不同的环节 判断改正题和补全文章细节题 通过完成以上任务后 学生就能够依靠查读的 方法对文章有进一步的理解和把握 Step 4 Deduction 推断推断 Purpose To get the students to have a deep understanding of the text relying on their own inference and deduction 目 的 让学生依靠自己的推理达到深层次的理解文章内涵 1 Ask the students to answer three difficult questions according to the text 2 Ask the students to find out the words that indicate the writer s feeling about being a volcanologist 设计理念设计理念 对于文章表层理解之后 要依据自己的理解感悟一些深层次的问题 比如文章没直接表述出来的内容或作者时不时表达的思想感受 以此做到由浅 入深 由表及里的把握 尤其在问到第三个问题时 为何熔岩比山体崩发更危 险 由于理解上有一定难度 我在这里加上了一段 FLASH 动画来帮助学生理解 动画很形象地表现出岩石崩发时周围没有居民 而滚烫的熔岩流经很远 会埋 葬途经的一切 对人类造成危害 Step 5 Association 联想联想 Purpose To get the students to associate themselves with the occupation volcanologist 目 的 让学生把自己将来的职业向火山学家靠拢 激发他们为人类做贡献的 热情 T The key word of the text is exciting which is the focus of the passage By telling the readers his everyday work the importance of his job his first sight of volcano eruption and his sincere love for his job the author proves it s his chief enjoyment to be a volcanologist And I appreciate the writer s attitude towards nature We should love nature and we can do something to minimize the damage caused by natural forces Do you want to become a volcanologist So let s suppose a situation If the writer came to our classroom what would you talk about Make up a dialogue with your partner 设计理念设计理念 通过本节阅读课的学习 让学生了解火山学家职业的独特性 既危 险艰难 又令人振奋 充满挑战 以此激发学生学习科学家不畏艰险 勇于为 人类做贡献的伟大精神 并且 争取使学生把自己将来的职业选择向火山学家 靠拢 在这里由一个问题 你是否想当火山学家 设置一个情景 假设书中 作者来到班级 学生会和他有怎样的交流呢 刺激他们努力学习 刻苦钻研 将来为全人类做出贡献 源于此 才设计了最后一个联想讨论的环节 Step 6 Homework 作业作业 Purpose To put their piffling thoughts together and practise their writing ability 目 的 使学生把刚才讨论中展现出来的琐碎思想整合在一起 针对他们是否 想成为火山学家进行写作锻炼 锻炼学生的写作能力 Try to write a short composition about the reason why you want to become a volcanolo
