Unit 3 Computers I. 单元教学目标II. 目标语言III. 教材分析与教材重组1. 教材分析本单元以computers为话题，旨在通过单元教学，综合听、说、读、写等多种形式，使学生了解计算机和信息技术的产生和发展过程及其在我们的学习、工作、娱乐等生活中所起的重要作用，激发学生对信息技术的兴趣。

1.1 Warming up提供几幅与计算机有关的图片，形象地说明了计算机的发展历程，并用三个问题引发学生对这一话题的思考，从而起到热身的作用。

1.2 Pre-reading根据文章内容预设问题，检查学生对computers相关知识及应用的了解。

学生对computers的了解可能参差不齐，这更能激发学生想获取更多知识的欲望，从而引出下面的阅读文章——WHO AM I?。

1.3 Reading中以别致的标题WHO AM I?引起学生的好奇心，使学生迫不急待地阅读这篇文章，并判断出“I”是computer，从而对文章的内容印象更深刻。

文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现状，并用拟人化的口吻表达了computers乐于为人类服务的精神。

1.4 Comprehending 1 通过scanning的方式完成反映计算机发展历程的时间进程；2 通过填表的形式帮助学生宏观梳理文章结构，找出每个段落的主题句（论点）及具体的支持性论据；3 是读后讨论，要求学生结合自己的生活实际讨论计算机如何改变了我们的生活。

1.5 Learning about language分词汇（Discovering useful words and expressions）和语法（Discovering useful structures）两大部分。

Discovering useful words and expressions 1 根据单词释义写出相对应的词汇，考查学生对WHO AM I? 文章中的重要词汇及短语的理解。

人教版高中英语必修2 Unit 3 Computers第一课时教案

人教版高中英语必修2 Unit 3 Computers第一课时教案Period One Intensive ReadingTeaching Goals：1. Target Languagea. The Key Words and Phrasessimplify logically technological revolution solve from…on personalas a result totally so…that network Web application explore anyhow human raceb. T he Key SentencesOver time my memory has developed so much that, like an elephant, I never forget anything I have been told!And my memory became so large that even I couldn’t believe it!2. Ability Goals：Enable students to learn about the development and history of computers.Teaching Important & Difficult Points：Understand how details are used to support topic sentences.Teaching Methods:Prediction, scanning and discussion.Teaching Procedures & WaysStep I Warming-upT: How many of you have computers in your home? Please put up your hands.Ss :respond accordingly.T: What do you usually do on your computers?Ss:Type documents/homework, listen to music, watch videos, play games, search on the Internet, send mails …T: When I were at your age, I knew nothing about computers. Most Chinese families never heard about it. However, in recent years, computers have become more and more popular, and most families in cities have one or more than one computer in their home. And some families in villages also have their own computers. Computers make life more convenient and colorful. However, it took a long time for humans to have computers that we see today. Now look at the pictures on page 17 and discuss what they have in common. Then think about Questions 2 & 3.Suggested answers:1.These pictures are all technological inventions.2.From these pictures, we know computers have experienced a long development process,and the development will never stop.3.(There may be various answers.)Step II Pre-readingPrediction: Let students predict the content of the passage according to the pictures and the title. This will involve students in active thinking and exploring.Then let them make a list of the ways computers are used today.Sample list: date processing; industrial design; learning and teaching aids; TV program editing; entertainment (watch TV/video, listen to music, play games, online chat…) communication (e-mail, e-card, instant message) …T: Now look at the inventions in activity 3. First check their meanings in your dictionaries. Then put them in the order according to the time when they appeared.Help students understand the meanings of the words: analytical, calculate and universal. Note:Universal machine is also known as Alan Turing's “universal computing machine”, is capable of computing any algorithm.Students may have different answers. They will check it after reading the passage.T: Have you put them in the right order? You will find it after reading the passage. Now turn to page 18 please.Step III ReadingSkimmingGet students read the whole passage and try to get the main idea of it.After readingT: What does “I” in the title refer to?Ss: Computer.T: What is the main idea of the passage?Ss: The passage is mainly about the history and development of computers.ScanningT: Correct! Now read the passage and finish the timeline. With this timeline, you will have a clear idea of the development of computer.Check the answers.T: The passage has three paragraphs. Find out the topic sentence of each paragraph, and the details that are used to support the topic sentences. Then complete the chart in activity 2.the topic sentences are not standing there alone, they are supported with details and date, which make the topic sentences more convincing. Now I will play the tape of this passage. Listen and find out/underline the difficult words and expressions.Teacher gives some explanations.T: What can be “over time” replaced by?Ss: As time goes by.T: How do you understand the word “simplify”? Look! (on the board: simple+-ify). -ify is a suffix which means to turn into, make or become. For example, beautify. So if you know the meaning of “simple”, you can easily get the meaning of “simplify”. Who can tell me its meaning?S: To make something easier or less complicated.T: What does “it” in line 9 refer to?Ss: It refers to the fact that computer was programmed by an operator who used cards with holes.T: Why was Alan Turing called computer’s real father?S: I guess that’s because Alan made computer more powerful, which could solve any difficult mathematical problem.T: What does “this reality” in line 15 refer to?S: It refers to the reality that computer had grown as large as a room.T: In paragraph two, there are two sentences which contain the use of “so…that…” structure. Underline them and study carefully.Show the following on the screen/board:●Over time my memory has developed so much that, like an elephant, I never forgetanything I have been told!●And my memory became so large that even I couldn’t believe it!Help students sum up the form and function of this structure:Form:so + adj./adv. + that + clauseFunction:This structure is used when emphasizing the degree or amount of something by saying what the result is.Step IV DiscussionT: Discuss this question in groups: Why do many countries want to host the Olympic Games while others do not? Use the mind map below to help you. Then prepare for a class discussion. Put forward your ideas and give reasons for your choices.T: Why do many countries want to host the Olympic Games?S: Hosting the games has a major effect on the economy and brings international prestige to the country. Thousands and thousands of visitors come to the game s and the host cities are permanently improved. By planting trees and creating parks, the city becomes more attractive for tourists.S: It helps to strengthen the spirit of patriotism and also can create more job opportunities and improve the quality of employment.S: The Olympic Games is the world's largest and highest level, and most widely influential sports event. The people of all countries enhance mutual understanding and friendship and safeguarding peace in the world event. Besides, the hosting of the Olympic Games is not only a country's comprehensive strength of the comprehensive test, but also to expand a country’ influence around the world, and at the same time promote their own development as a good opportunity.T: Well done! Why do many countries don’t want to host the Olympic Games?S: Preparing for the Olympics Games is a huge undertaking. Just like the athletes, the host city spends years getting ready for the event. Before deciding which city will host the Olympic Games, the International Olympic Committee (IOC) has to examine bids from allover the world. Bidding for the games begins about ten years in advance. Without preparing a very strong bid1, a city will not win the competition to host the games.S: Hosting the Olympic Games take so long time and so much money to prepare. Building the infrastructure costs huge amounts of money. Holding the World Cup in 2002 in Japan and South Korea, for example, meant that ten new stadiums had to be built, as well as many hotels and an improved transport system. In Beijing, after winning the bid, the government began major construction projects — the extension of the underground, the improvement of the airport and the building of new motorways. Each host city must also build an Olympic village for the athletes.S: Too many visitors may do harm to the environment of the city, in addition, the venues and buildings may be wasted after the Olympic Games.T: Well done! As every coin has two sides, hosting the Olympic Games has its advantages and disadvantages. For our powerful China, it is a good opportunity to host the Olympic Games which can benefit us a lot.Step V Homework (retelling)T: Suppose you work for an information technology magazine. Write a short passage which briefly introduces the history and development of computers. Don’t write in the first person.。
