Unit 2 Robots Ｉ．单元教学目标II．目标语言III．教材分析与教材重组1.教材分析本单元以机器人和科幻小说为话题，介绍了20世纪世界知名的科幻小说家Isaac Asimov写于1951的Satisfaction Guaranteed 和作者的生平。

通过本单元的教学，旨在让学生了解科幻小说最大的特征在于，它赋予了“幻想”依靠科技在未来得以实现的极大可能，甚至有些“科学幻想”在多年以后，的确在科学上成为了现实。

如Isaac Asimov1951年描述的机器人的部分功能已经被应用于现实生活和工作中。

在教学中，要鼓励学生敢于幻想，大胆创新，发挥自己丰富的想象力和创作力，写出独具特色的科幻文章。

1.1 WARMING UP介绍了什么是机器人，和不同种类及不同形状的机器人。

1.2 PRE-READING 通过讨论机器人是否像人类一样有自己的思维，是否有感情引出Isaac Asimov的科幻小说Satisfaction Guaranteed。

为本单元的READING 做好了铺垫。

1.3 READING课文是Isaac Asimov写于1951的科幻小说SatisfactionGuaranteed。

文中描述的机器人Tony是一个除去面无表情外，身材高大，相貌英俊，聪明机智的完美男人。

仅三周的时间就使女主人坠入爱河。

1.4 COMPREHENDING共有2部分，第一部分是关于课文内容的5个问答题，旨在考察学生对课文的理解。

第二部分要求学生比较机器人Tony在physical, mental, emotional 三方面与人的异同。

与PRE-READING 部分的问题相呼应。

1.5 LEARNING ABOUT LANGUAGE 分为两部分，Discovering useful words andexpressions是本单元词汇练习题；Discovering useful structures是本单元语法练习题，通过本单元的学习，要求学生熟练掌握不定式的被动语态。

1.6 USING LANGUAGE分为两部分，Listening ,discussing and writing部分内容是Molly 和Kate 讨论Satisfaction Guaranteed的对话录音，要求学生根据对话内容学会运用表达自己观点的常用句型。

这部分教学内容还要求学生以机器人为话题，充分发挥自己的想象力，谈论机器人做家务的利与弊。

并且要求自己动手设计机器人，附上文字说明。

Reading and discussing 部分的内容是科幻小说家Isaac Asimov的生平介绍。

文章后附有练习题。

第一题要求学生根据时间线，了解在作者生命中发生的重要事件。

第二、三题要求学生讨论Isaac Asimov的“机器人三定律”。

Teaching methods教学方Discussing, explaining, reading and practisingTeaching aids教具准备The multimedia computerTeaching procedures & ways教学过程与方式Step I Warming upDeal with Warming up. Present photos of different kinds of robots. Then ask them to say something about his or her favorite robot.T: Good morning /afternoon, class!Ss: Good morning/ afternoon, Mr. /Ms…T: In this class we are going to learn about robots. Who would like to tell me what a robot is?S1:A robot is a machine.T: What kind of machine?S2: A robot is a kind of machine that can do a variety of often complex human tasks.T: How can a robot perform human tasks?S3: A robot is controlled by a computer.T: You are right. Then we can give the definition of a robot like this: A robot is a machine designed to do jobs that are usually performed by humans. Robots are programmed and controlled by a computer. Now look at some pictures. Divide them into different types and decide your favorite one.Step II Pre-readingAsk students to discuss the questions in pre-reading in groups. Students are encouraged to speak out their opinion freely, no matter what it is. Teacher should encourage students to use their imagination.Step III ReadingDeal with the reading part.ScanningAsk the students to scan the text and find out what Tony looks like.T: Ok. I’m glad you had a heated discussion. Now I’d like you to meet Tony-- a robot that looks exactly like a human being. He is a character in the science fiction Satisfaction Guaranteed by Isaac Asimov. Please read the text and find the answers to the following questions.Show the following questions on the PowerPoint.1. What did Tony look like?2. What did Tony do to make Claire and her home elegant?Several minutes later check the answers with the whole class.Suggested answer:1. He was tall and handsome although his facial expressions never changed. His hair was smooth and black and his voice was deep.2. Tony gave Claire a new haircut and changed the makeup she wore. He also suggested Claire buy new curtains, cushions, a carpet and paint for the house and new dresses for herself. He made improvements on the house so that the house looked very elegant.Careful readingComprehending questions on Page 12Ask students to read the text carefully and then discuss the comprehending questions on Page 12 in groups.T: Now let’s read the text carefully and then do the comprehending exercises on Page 12.Several minutes later check the answers with the whole class.Suggested answers:1.1. He opened the curtains so that the other women—Clai re‘s guests couldsee them.1.2 He had prevented Claire from harming herself through her own sense of failure.1.3 Because the company (designers) cannot have women falling in love with machines.1.4 Various answers can be accepted.1.5 When she first saw the robot, she felt alarmed. Tony didn’t look likea machine at all.She felt embarrassed when Tony asked her whether she needed help dressing.Claire thought it was ridiculous to be offered sympathy by a robot.She was amazed by the fingernails and the softness and warmth of his skin.She screamed, pushed him away and ran to her room for the rest of the day.What a sweet victory to be envied by those women. She might not as beautiful as them, but none of them had such a handsome lover. Then she remembered—Tony was just a machine. She cried all night.2.Claire’s emotion developmentAfter dealing with the comprehending exercises, ask students to work together to find how Claire’s emotion developed.Suggested answer:At first refused to have Tony at her house---accept him----trust him---- proud of him----love him---sad to remember he was just a machineT: From her emotion development, we can see Tony was designed as a Mr. Perfect. He is designed not to harm Claire or allow her to be harmed. This is one of Isaac’s three laws for robots. Later in this unit we will learn more about his three laws.Characteristics of science fictionT: As you know, the story was written in 1951. With the development of science, some of the functions performed by Tony have come true. From this story we can draw a conclusion:Science fiction is often based on scientific principles and technology. Science fiction may make predictions about life in the future.Please remember these are some characteristics of science fiction. If you are interested, you may write short science fictions in your spare time.ExplanationDuring this procedure Teacher will play the tape recording for students. Students will underline the difficult sentences. After listening to the tape, Teacher will explain the text and deal with language problems.T: Now we will deal with some difficult language focuses. Now I will play the recording of the text for you. Please make a mark where you have difficulties.After listening to the recording, explain the difficult sentences to students. Before explaining the difficult points, students are asked to refer to the notes to the text on Page88-89.T: Do you have any difficulties with the text？S1:Could you please explain the sentence to us：She felt embarrassed and quickly told him to go. T: Because Tony didn’t look like a machine at all, when Tony offered to help her get dressed, she was embarrassed, perhaps shy to get a “man” help her dressing.S2: How to understand this sentence: Claire thought it was ridiculous to be offered sympathy by a robot.T: In spite of the fact that Tony looked so human, he was just a machine. So Claire thought it was foolish that Tony offered her sympathy. Do you have any other questions?Ss: No.T: Maybe someday we will have robots that have feelings and can also think for themselves. Please remember science fiction reflects scientific thought; things-to-come based on things-on-hand. Ok, that’s all for today.
