During his whole life, Mark Twain carried on many kinds of jobs. From 1864, he became a reporter and travelled in Europe. By the end of his life in 1910, he had become known as the perfect example of American author. Behind the mask of humour and satire, his writing often criticized social morals, politics and human nature, making his literature a unique reflection of the American experience in the latter part of thenineteenth century. In the 1890s Mark Twain became very poor. To recover from the bankruptcy, he started a world lecture tour, during which one of his daughters died. The death of his wife and his second daughter darkened his later years.Mark Twain died on April 21, 1910.Time line of the events1835- Haley's Comet welcomed the birth of Samuel Langhorn Clemens. He was born in Florida, MO on November 30. His mom was Jane and his dad was John. He was six of seven kids.1857- The Clemens family moved to Hannibal, MO.1862- Mark Twain's dad, John Marshall died at age 49.1847- 1856- He worked for his brother for newspapers then went to St. Louis, New York City, Philadelphia and Cincinnati to work at a print shop. Then went to help his brothers with the newspaper in Kakoki, Iowa.1858- Mark made his plans to travel to South America, but when he started down Mississippi River, he took a break from the river and went to New Orleans. While he was there, he met Horace Bixby and made him teach him how to be a riverboat pilot.1859- In April, Mark Twain became a licensed riverboat pilot.1863- Clemens began to work for the newspaper in Virginia City, Nevada. This is when he started to use the name, "Mark Twain." Mark Twain means safe water.1866- Twain traveled to Hawaii to write articled in the newspaper.

From heart disease. Haley's Comet visited again just like the year of his birth.「苦行記」(Roughing It)，「密西西比河上的生活」(Life on the Mississippi)，「湯姆歷險記」(The Adventures of Tom Sawyer, 1876)、「頑童流浪記」(The Adventures o f Huckleberry Finn, 1884) 、「鍍金時代」(The Gilded Age, 1873)、「海外浪跡」(A Tramp Abroad, 1880)、「王子與貧民」(The Prince and the Pauper, 1882)、「亞瑟王廷之康乃迪克佬」(A Connecticut Yankee in King Arthur's Court, 1889)、「傻威爾遜之悲劇」(The Tragedy of Pudding Head Wilson, 1891)、「聖女貞德回憶錄」(Personal Recollections of Joan of Arc, 1896)，The writer’s introduction to The Adventures of Tom Sawyer (1876)Most of the adventures recorded in this book really happened; one or two were experiences of my own, the rest those of boys who were schoolmates of mine. Huck Finn is drawn from life; Tom Sawyer also, but not from an individual —he is a combination of the three boys whom I knew. Although my book is intended mainly for the entertainment of boys and girls, I hope it will not be shocked by men and women, for part of my plan has been to try to pleasantly remind adults of what they once were themselves, and of how they felt and thought and talked, and what strange adventures they sometimes took part in.The Adventures of Tom SawyerThis edition presents Twain's classic American novel in an unabridged text with a reader's guide that's suitable for both children and adults. Mark Twain's classic novel, The Adventures ofHuckleberry Finn, tells the story of a teenaged misfit who finds himself floating on a raft down the Mississippi River with an escaping slave, Jim. In the course of their perilous journey, Huck and Jim meet adventure, danger, and a cast of characters who are sometimes menacing and often hilarious. Though some of the situations in Huckleberry Finn are funny in themselves (the cockeyed Shakespeare production in Chapter 21 leaps instantly to mind), this book's humor is found mostly in Huck's unique worldview and his way of expressing himself. Describing his brief sojourn with the Widow Douglas after she adopts him, Huck says: "After supper she got out her book and learned me about Moses and the Bulrushers,and I was in a sweat to find out all about him; but by and by she let it out that Moses had been dead a considerable long time; so then I didn't care no more about him, because I don't take any stock in dead people." Underlying Twain's good humor is a dark subcurrent of Antebellum cruelty and injustice that makes The Adventures of Huckleberry Finn a frequently funny book with a serious message.His quotation: "Love your enemy, it will scare the hell out of them.”“The man who does not read books has no advantage over the man that cannot read them.”“Always tell the truth; then you don’t have to remember anything.”Humor has been well defined as thinking in fun while feelingin earnest.”幽默被人正确地解释为“以诚挚表达感受，寓深思于嬉笑”。

2020-2021学年高中英语云南同步教案：Unit 3 Computer阅读(人教新课标必修2)

2022-2021学年高中英语云南同步教案：Unit 3 Computer阅读（人教新课标必修2）高中英语必修二Unit 3 Computers阅读课的教学设计一、教学设计思路本课设计以WHO AM I?为课堂教学材料，以同学现实生活为动身点和归宿点，以我国《标准》指导教学目标制定，以“5C”外语学习思想指导教学环节设计，旨在进展同学的语言实际运用力气。

本设计以同学中心，运用了图示理论，接受了pair work, group work, class work 等活动形式，串联成环，前后环环相扣，挂念同学理解课文，用自己的英语重新诠释课文，并初步具备学问迁移力气。

二、学习任务分析本单元的中心话题是“计算机”，内容涉及计算机的进展历史、计算机的应用等，其中还谈到包括计算机在内的几种信息技术的载体、智能计算机的制造等等。

不过，整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业学问介绍起来也浅显易懂。

本主旨语篇WHO AM I ?以计算机的口吻自述其进展演化的历史以及计算机在当今世界各个领域的运用。

表达了计算机的进展变化之快以及在生活中用途之广。

三、学习者分析计算机这一话题虽然好玩，但本单元所选语言材料属于科普类说明文，内容较为抽样，文章中也不乏一些专业术语，对于高一同学来说有确定的难度。

目前，同学上课以interpersonal的沟通为主，而interpretative和presentational形式比重不够。

由于文化教学不够重视，同学的跨文化意识不高。

此外，同学跨学科学习的意识不够，语言和信息的双向促进关系的生疏不够。

对于比较策略主要运用在英汉汉英互译的语言层面，未进入文化比较和思维比较。

同学的课外语言活动环境不够丰富和重视程度不够，通常以词汇、语法和写作练习为主，缺乏真实的语言运用。

四、教学目标(1) Language Skills：1. Use “decision making” expressions like “I believe... in my opinion, etc” correctly.（activity 1）2. Develop their predicting and reorganizing skills.（activity 2,3,4,6）3. Write an 100-word passage on “My Robot Friend----Alice”（Task）(2) Language Knowledge：1. Reorganize and share their backgroud information of computers.(activity 1)2. Find and retell the grammar structure of the Present Perfect Passive Voice. (activ ity 5)(3) Emotions and Attitudes1. 通过争辩，能归纳和陈述网络给学校带来的影响；2. 通过辩论，能对外来网络布满奇异，激发自己的制造力的同时形成健康的网络使用态度和习惯。

【教案】Unit3The+New+Age+of+Invention教学设计外研版(2019必修第三册

新外研版高中英语Book 3 Unit 3The New Age of Invention课标分析通过本堂课的教学，我对《普通高中英语课程标准》有了更深刻的认识和体会。

一．注重培养学生的综合语言运用能力。

《普通高中英语课程标准》中指出：根据高中学生认知能力发展的特点和学业发展的需求，高中英语课程应培养学生听，说，读，写四种语言技能。

其中，听和读是输入，说和写是输出。

只有通过听读达到足够的语言输入，学生才能通过说和写输出一定的语言信息。

我在本堂课的阅读当中，渗透了本单元相关的话题词汇以及引导学生了解科学的相关要素。

最重要的是积累了写作的一些常用句型句式。

二．注重培养学生的学习策略，自我学习能力及合作精神。

《普通高中英语课程标准》中指出，教师要在教学过程中培养学生积极有效的学习策略，自主学习意识和自主学习能力，以及兴盛积极向上的学习态度，培养合作意识和合作精神。

我在本堂课中，通过阅读任务以及小组活动的设置培养学生的学习策略，自主学习意识和自主学习能力，以及形成积极向上的学习态度，培养合作意识和合作精神，并产生了良好的学习效果。

教材分析外研版高中英语教材的设置每一个模块围绕一个话题展开，提供话题相关词汇，文章等等。

第三册第三模块教材，围绕The world of science话题展开。

本单元主题语境为“人与社会”。

具体内容为科技发展和科学精神，旨在引导学生深入思考科学与生活之间的关系，培养学生对待科学的态度和批判性的思维，并引导学生尝试使用科学改变自己的生活。

本文以问答的形式介绍了古今中外人类的伟大发明和新发明时代的产物，这些发明给生活带来的巨大变化以及发明的原动力。

语篇的意图在于激发学生了解现代科技发展的趋势，加深对单元主题的认知。

本文的语篇类型为访谈，文章结构包括过去的发明、当代的发明和发明的原动力三个部分，各部分内容之间过渡自然、衔接紧密，访谈语言较为正式，并含有科技类专有名词，需要教师辅助学生理解访谈内容。
