高二英语 Unit3 The world online Task1教学设计 牛津译林版选修7

高中新课程新教材英语学科教学设计单元整体教学是发展学生核心素养、落实课改要求的有效途径。

本单元的教学设计以单元大概念和《普通高中英语课程标准》（2017 版2022 年修订）（以下简称《课程标准》）为理论指导，以各板块小概念为载体，围绕英语课程六要素，结合单元各语篇，依据教、学、评一体化的要求设计而成。

具体设计思路如下：1.单元整体教学设计理论根据：根据《课程标准》，普通高中英语课程以英语活动观为依托，强调对学生语言能力、文化意识、思维品质和学习能力的综合培养，以期落实立德树人的根本目的。

本单元的教学设计，基于《课程标准》，坚持以大概念为指导，整合教学内容，优化教学方式，以主题为引领，以语篇为依托，通过设计层层递进的教学活动，帮助学生理解小概念，进而促成单元大概念的生成，落实英语核心素养的培养。

2.单元整体教学设计亮点表现：⑴ 教学设计以大观念为统摄，整合教学板块内在关系本单元的主题为“网络世界”，主题意义为如何恰当的使用网络。

单元板块关系图如下：基于单元板块的内部关系，本单元的单元小观念为：1. 了解和认识互联网的发展和使用；2. 概括和辨析互联网的利弊；3. 反思和迁移如何恰当使用。

本单元的大观念为：网络世界，人人有责，恰当使用是关键。

⑵ 各板块教学中文化知识、语言能力互相渗透，促进学生思维品质和学习能力的培养各板块教学内容不是孤立存在的，基于各部分小概念的课程设计和教学内容是相互联系的，因此单元Wele to the unit 板块的话题是互联网发展史上的三座里程碑，即邮件、网络摄像头和表情包。

第一段文字简要描述了Ray Tomlinson 在1971 年发送了第一封邮件。

第二段文字讲述了电脑科学家为何要发明网络摄像头。

第三段文字讲述了表情包的诞生和灵感来源。

Reading 语篇主要讲的是互联网的连接功能给人类带来的三个好处，以此阐述观点：互联网是一个无疆的世界。

同时作者也提及连接存在着问题，以及如何能让互联网成为一个真正的无疆世界的建议。

Unit 3 The world online教学设计Teaching Aims and requirements◆ Read two debates and an information sheet◆ Listen to speeches about how people watch and listen to the news◆ Talk about the Internet and ask questions about facts and figures◆ Write an e-mail reporting facts and figures◆ Do research on the Internet and design a posterTeaching ProceduresWelcome to the unitStep 1: BrainstormingWith the rapid development of Internet, it has been influencing our daily life tremendously. Internet has transformed our lives and the way we communicate, we learn, we work and spend our free time. In fact, it has more or less changed every aspect of human society.Boys and girls，please read the instructions and focus on the four pictures. Then try your best to think of information you know about each picture. Anyway, I’ll giveyou a brief introduction first. (For example, “We are going to talk about how we use the Internet. Try to find how we can use the Internet and how the Internet can affect our lives.”)Picture 1What can people do on this website?What do we call this kind of website that providessearching services? (We call it search engine.)Do you know how to find information on the internetusing a search engine?What search engines do you know or often use? Which is your favorite search engine?Picture 2Have you ever heard of shopping online or bought anything online? What is shopping online like?What do you think would be the advantages of buying things online? (As online shopkeepers do not have to pay for the rental of a real shop, the products sold on line are usually cheaper than those in real shops. It is easy and convenient to compare aproduct in several online shops. Paying for things issimple as you just key in the credit card number andconfirm the payment online. The delivery is usuallyquick and the online shops provide delivery to yourhome. The most important thing is that shopping onlinesaves a lot of time. )What do you think would be the disadvantages of online shopping?(Because people can only see pictures of the products online, sometimes you could receive something that was not what you really wanted. The safety of the payment is not one hundred percent guaranteed as someone may steal the account numbers or pin numbers of your credit cards registered online. Also, some people falsely advertise products and then steal customers’ money. )Picture 3Have you ever tried talking with your parents or friends online? What was it like?What devices do you need if you want to talk with peopleonline?(A computer connected to the Internet, a web-camera, aweb-microphone and web-talking software.)What are the good points and bad points of online talking?(There are many good things about online talking. People can savea lot of money instead of paying for long-distance calls. People cankeep in touch with family members or friends wherever they are inthe world. There are negative things too. The quality of the pictures or voice depends on the speed of the network transfer. Many people talk with online friends without realizing that their pictures could be used by others in illegal ways. )Which way of communication do you prefer, talking face to face, talking over the telephone, talking online or talking online with a web-camera? Why?Picture 4Have you tried other online services that are not mentionedhere? Which ones?What other online services do you think we will need or have in the future?What role do you think the Internet will play in the future?Do you think it is a good idea to “live” on the Internet completely?Step 2: Sharing information1. To work in groups of four or to form your own groups. Let’s read the three questions under the pictures.2. Exchange your opinions and discuss the three questions among your group members. I want all of you to fully participate in the discussion and express your opinions freely. Then some of you are required to report your answers to the class. Remember it may be more interesting for groups to exchange and compare your answers.Step 3: Discussion:What are the advantages and disadvantages of the Internet?Sample answersWith the rapid development of Internet, it has been influencing our daily life tremendously. Internet has transformed our lives and the way we communicate, how we learn, how we work and spend free time. In fact, it has more or less changed every aspect of human society.We can benefit a lot from Internet. Firstly, it is more convenient than ever before. Internet has greatly shortened the distance among human beings. E-mail is much more efficient. To do some research work, we can search for relevant information on Internet without leaving our home. Secondly, we can reduce our cost greatly. We needn’t spend lots of time and money in printing and posting. What we have to do now is just to send documents through Internet and it almost costs nothing.Although Internet has brought us many benefits, there can be no denying that it has brought us many inconveniences, even harms as well. First of all, it is not safe on Internet. Maybe thousands of people are staring at you when you log onto Internet. Your private information, such as your account and password, is easy to be let out. On the other hand, with the sharply increasing amount of time spent on Internet, we are starting to lose ourselves, especially for those youngsters. We are getting more and more indifferent to people around us. The more we communicate, the lonelier we feel.However, Internet itself is neither right nor wrong. We can benefit from it and may also suffer from it. Nobody can hold back the step forward of Internet. If we resisted it, we would certainly lag behind other nations. What we should do is to take full use of its advantages and try to avoid the harms it may bring as well.Step 4: Homework:1. Collect more information about the development of the Internet.2. Prepare the Reading part.Reading The effects of the Internet on our livesStep1: Lead-inNowadays, internet is playing an increasingly significant role in our society. Since its appearance, it has brought enormous changes to our lives. It seems that no one can escape from the influence of it. As to whether it is a blessing or a curse, there is a long-running controversial debate. Some people think that increased use of the Internet leads to social isolation and depression. People who spend more time on the Internet spend less time socializing with peers, communicate less within the family and fell more lonely and depressed.Have a discussion about the good and bad effects of the Internet in group. Try to fill in the table below:Step 2: Fast reading for general ideasGo through the passage as quickly as possible and try to find answers to the three questions in part A. Just focus on and identify the information needed to answer these questions.AnswersA 1 They are about different effects of the Internet on our lives.2 Two.3 Uncontrolled information and the change in the way people spend their time. Step 3: Detailed reading for important information1. Let’s read the passage a second time and complete Parts C1 and C2.2. Read the text again and choose the best answers according to the text:⑴According to the survey, children use the Internet mostly to __________.A. chatB. play gamesC. help with their studiesD. advance knowledge about hobbies⑵What is the most important thing in building a friendship?A. common interestsB. appearanceC. ageD. popularity⑶What is the worst problem of eBay?A. false informationB. people don’t know how to use a computerC. things selling on the Internet don’t existD. people are used to the traditional ways of buying⑷The clinic was opened to____________.A. help people surf the InternetB. be an Internet caféC. make people spend their time with their familyD. help people who are addicted to computer gamesNow, read the Reading strategy on page 35. Pay attention to how to read an argument, especially, how to find each side’s view, how to find a list of points, and what each side believes. Read the passage again and try to fill in the table below.Step 4: Practice:1. Now let’s complete Parts D on page 36.AnswersD 1 f 2 b 3 a 4 g 5 c 6 d 7 h 8 e2. A university student sent an e-mail to his mother. Read it in Part E and fill in the blanks with words given in the box.Step 5: Post-reading activities1. Pair work:What do you know about the Internet? Try to find as much information as you can, and report your information to your partner.2. Group work:Undoubtedly, in the future, the Internet will still play a very important role in human’s life. But they’ll certainly be advanced than those of today. Let’s work in groups and guess how we can use the Internet in the future. .3. Let’s come to Part F. Work in pairs and share your opinions with each other.4. Discussion: Does the Internet do us good or bad?Step 6: Language points:Step 7: Homework:1. Read the text again and again. Try to memorize the language points.2. Do Parts A1 and A2 on pages 118 of the Workbook.Word powerStep1: Brainstorming1. Guessing Game:At the beginning of today’s class, l et’s play a guessing game. Here are several cards, each of which is related to the Internet or a computer. I’d like one of you to give a brief description of the each device and other students to guess what it is.2. Next time you are in our school’s computer room, notice how we operate a computer.Step 2: Vocabulary learning1. Do you know about the operation of a computer and the knowledge of Internet? We’ll conduct a question-and-answer activity. Please speak out what you know as much as possible. The purpose of this activity is to make you more familiar with the words and terms connected to the Internet.2. Read Part A and make sure that you know what these words in blue mean or referto in Chinese.3. Focus on Part B and read the sentences individually first. Make sure that you know what these words mean or refer to in Chinese.4. Read the e-mail in Part C, which was written by Kenny to his grandpa about the Internet. You are required to complete the e-mail with the words discussed on page 38. Try to guess the meanings of the new words from the context. Then we’ll check the answers.Step 3: Vocabulary extension1. In Part D, you will learn some abbreviations that people use in Internet chat rooms. Whether you have used these abbreviations before? As the abbreviations use only the first letters of each word, it is fast to type them when chatting online. It is very popular among young people to use these words.2. You can sometimes work out what an Internet abbreviation stands for by reading the letters out loud, for example:B4 (before)OIC (oh, I see.)CUL8R (see you later.)I’ll explain some other expressions to you:BTW (by the way)BFN (bye for now)3. Complete Part D individually. Then we’ll check the answers.4. Reading:words: 288 time: 4’20’’The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the U.S. military. Originally limited to researchers at a handful of universities and government facilities, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 million U.S. citizens had access to the Internet at home or work. More and more Americans are paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet.Internet banking is also becoming increasingly popular. With lower overhead costs interms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charge lower rates on loans than traditional banks. “Brick and mortar" banks are increasingly offering online banking services via transactional websites to complement their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double or triple during the next two or three years.Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit or debit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need sophisticated security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that outsiders cannot disrupt the organization’s internal networks or gain unauthorized access to the organization’s computer systems and data.1. According to the text, Internet banking ________.A. requires minimal usage feesB. offers price advantages to usersC. is more efficient than traditional bankingD. is environmentally-conscious2. The term “brick and mortar banks” (Line 3, Para.2) refers to ________.A. banks with dependable reputationsB. banks with competitive interest ratesC. banks with traditional walk-in servicesD. banks with reliable on-line services3. The last sentence of the third paragraph tells us that ________.A. any organization's networks may be at risk of security breachesB. current technology cannot safeguard against unauthorized access to online networksC. information security should be a pressing concern for Internet commerceD. organizations must secure their networks and data against unauthorized use4. What is this text mainly about?A. Conveniences brought to consumers through use of the Internet.B. Implications of increasing commercial use of the Internet.C. Security risks posed by commercial use of the Internet.D. Advantages of Internet banking versus traditional banking.5. Which commercial usage of the Internet does the author NOT refer to?A. Buying airline tickets.B. Trading stocks.C. Applying for a credit card.D. Opening a bank account.Keys:1-5 BCDBCGrammar and UsageStep 1: General introductionThe grammar in this unit focuses on linking verbs. You’ll review what a linking verb’s function is in a sentence and what verbs can be used as linking verbs. You are expected to apply the rules you have learnt to complete some written tasks.Step 2: Exercises:Fill in the blanks with proper linking verbs:1. Wood ___ hard.2.

主题句引领，衔接词呼应，凸显文章结构：总——分——总。

首段即表明论点，二、三、四段为分论点，详细阐述了互联网给人类生活带来的三个好处；末段进行总结，指出互联网连接存在一些问题并提出建议：正确、负责任地使用网络。

且末段尾句与标题相呼应。

此外，分论点部分多次使用举例子、作比较的论证方法，使论证更具体化、更具说服力。

暗线则是围绕标题的多层含义层层完善，最终结合作者的建议达到真正的网络无疆界。

是一个无疆世界的论述，从而形成批判性思维，合理且负责任地使用互联网。
