Sunny Wednesday
I am very happy today，because this is the first day that I has spent with my owner，Susan.Susan is a 6－year－old sick girl.She cannot go out with other children because of her poor health.So her parents bought me as her companion.There are different types of robot pets in the store.Her mom preferred the seal－type robot，while her dad thought the lovely dog would be a good companion.But Susan loves kitty very much.She insisted on having me as her companion.So they chose me.
The shop assistant told them I have more than just entertainment value，offering companionship and a variety of other services to the sick.A network system will enable me to speak to the children in a natural way，especially to children who are sick，and this will make them more comfortable.
I can be connected via cell phone or ISDN line to a network system center，allowing health workers or parents to send medical information and encouraging messages to the sick.I'm endowed with 100 phrases，ranging from the light－hearted (“Today is the karaoke party.Let's sing a lot.”) to more practical information (“It is three o'clock.It is time to have medicine.”)．
Susan smiled a lot and her parents said she has never spent a happier day.I am happy too because I've brought pleasure to her.

It was clear that Claire had fallen in love with Tony.
很显然，克莱尔已爱上了托尼。
It seems unlikely that she will refuse the offer.
看上去她不太可能拒绝给她的帮助。

威廉肯定会考得很好。
It is absurd that he believes the number 13 has brought him the bad luck.

(4)It seems/happens...＋that clause.
It seems that they are in urgent need of help.
好像他们现在急需帮助。
It happens that the prettiest birds are the worst singers.
很碰巧，最漂亮的鸟是最差的歌手。
要注意的是这种结构与强调结构的区别。试比较：
It was Tony that managed to help her in time.
是托尼及时设法帮助了她。
It was then that Claire realized that Tony had opened the curtains of the front window.
也就在这时候，克莱尔才意识到托尼早就把前边窗户的窗帘拉开了。
5．So Claire borrowed a pile of books from the library for him to read，or rather，scan.
于是，克莱尔从图书馆借了一堆书给托尼阅读，或者说给他浏览一下。

他住在伦敦，更准确地说是在伦敦郊区。

你得是16岁才能买便宜的票，更准确地说是16岁以下。
6．...you cannot have women falling in love with machines.
……总不能让女人爱上机器。
这句话的结构是have＋n.＋doing，have的意思是cause sb.to do，它与have＋sb.＋do结构的意思有时略有不同，前者讲的是过程，后者叙述的是当时的情况。
As soon as I got there，I tried to have John find me a house.
我一到那里，就试着让约翰给我找房子。
She had us all laughing at her jokes.
她的笑话让我们大笑。
另外，在have＋n.＋doing结构中，如果have用作否定时，其意思是not permit or allow。
I can't have you going everywhere and doing nothing all day.
我不能让你整天无所事事地东游西逛。
7．Asimov had both an extraordinary imagination that gave him the ability to explore future worlds and an amazing mind with which he searched for explanations of everything，in the present and the past.
阿西默夫不仅有超凡的想象力，使他能对未来世界进行探索，而且还有着惊人的智力，使他对现在的和过去的各种事物作出解释。
这个句子稍微有点复杂，现简要地分析一下：Asimov had both an extraordinary imagination and an amazing mind是这个句子的重要部分，动词不定式to explore future worlds修饰ability，with which引导的定语从句修饰an amazing mind。
with which是“介词＋which (whom)”的结构，其介词的选择受到一定的限制：或与前面的名词搭配有关(本句就是这样)，或与后面的动词或者词组搭配有关。
He seemed to be looking for the words with which he could express what he was thinking about.
他好像正在找能表达他想法的词语。
The car，for which I paid a lot of money，is now out of date.
我花很多钱买的这辆小汽车现在过时了。
二、文化背景知识
Robot
A robot can be defined as a programmable，self－controlled device consisting of electronic，electrical，or mechanical units.More generally，it is a machine that functions in place of a living agent.Robots are especially desirable for certain work functions because，unlike humans，they never get tired；they can endure physical conditions that are uncomfortable or even dangerous；they can operate in airless conditions；they do not get bored by repetition；and they cannot be distracted from the task at hand.
The concept of robots is a very old one yet the actual word “robot” was invented in the 20th century from the Czechoslovakian word robot or robotic meaning slave，servant，or forced labor.Robots don't have to look or act like humans but they do need to be flexible so they can perform different tasks.
Early industrial robots handled radioactive material in atomic labs and were called master/slave manipulators.They were connected together with mechanical linkages and steel cables.Remote arm manipulators can now be moved by push buttons，switches or joysticks.
Current robots have advanced sensory systems that process information and appear to function as if they have brains.Their “brain” is actually a form of computerized artificial intelligence (AI)．AI allows a robot to perceive conditions and decide upon a course of action based on those conditions.
A robot can include any of the following components：
effectors—“arms”，“legs”，“hands”，“feet”
sensors—parts that act like senses and can detect objects or things like heat and light and convert the object information into symbols that computers understand
computer—the brain that contains instructions called algorithms to control the robot
equipment—this includes tools and mechanical fixtures
Characteristics that make robots different from regular machinery are that robots usually function by themselves，are sensitive to their environment，adapt to variations in the environment or to errors in prior performance，are task－oriented and often have the ability to try different methods to accomplish a task.
Robot Timeline
270BC an ancient Greek engineer named Ctesibus made organs and water clocks with movable figures.
1818—Mary Shelley wrote “Frankenstein” which was about a frightening artificial life form created by Dr.Frankenstein.
1921—The term “robot” was first used in a play called “R.U.R.” or “Rossum's Universal Robots” by the Czech writer Karel Capek.The plot was simple：man makes robot then robot kills man!
1941—Science fiction writer Isaac Asimov first used the word “robotics” to describe the technology of robots and predicted the rise of a powerful robot industry.
1942—Asimov wrote “Runaround”，a story about robots which contained the “Three Laws of Robotics”：
A robot may not injure a human，or，through inaction，allow a human being to come to harm.
A robot must obey the orders by human beings except where such orders would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
1948—“Cybernetics”，an influence on artificial intelligence research was published by Norbert Wiener.
1956—George Devol and Joseph Engelberger formed the world's first robot company.
1959—Computer－assisted manufacturing was demonstrated at the Servomechanisms Lab at MIT.
1961—The first industrial robot was online in a General Motors automobile factory in New Jersey.It was called UNIMATE.
1963—The first artificial robotic arm to be controlled by a computer was designed.The Rancho Arm was designed as a tool for the handicapped and its six joints gave it the flexibility of a human arm.
1965—DENDRAL was the first expert system or program designed to execute the accumulated knowledge of subject experts.
1968—The octopus－like Tentacle Arm was developed by Marvin Minsky.
1969—The Stanford Arm was the first electrically powered，computer－controlled robot arm.
1970—Shakey was introduced as the first mobile robot controlled by artificial intelligence.It was produced by SRI International.
1974—A robotic arm (the Silver Arm) that performed small－parts assembly using feedback from touch and pressure sensors was designed.
1979—The Stanford Cart crossed a chair－filled room without human assistance.The cart had a TV camera mounted on a rail which took pictures from multiple angles and relayed them to a computer.The computer analyzed the distance between the cart and the obstacles.

2．理论依据
《普通高中英语课程标准》明确提出：“要通过设计丰富多彩的课内外学习活动，使学生在参与交际活动的过程中形成交际策略。”
教材内容分析
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发表于1951年的Satisfaction Guaranteed 和他的生平。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，的确在科学上成了现实。如Isaac Asimov 1951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。
教学内容如下：
Warming Up介绍了机器人的制造、种类、功能等等，再让学生分组列表，把自己熟悉的科幻文艺形式(科幻故事、电影、电脑游戏、电视剧、卡通等等)写出来，并进行简单地交流。
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。
Reading的课文是Isaac Asimov发表于1951年的科幻小说Satisfaction Guaranteed。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。
Comprehending共有3个练习，练习1是关于克莱尔的情感变化，练习2是关于课文内容的5个问答题，旨在考查学生对课文的理解；练习3要求学生比较机器人Tony在physical，mental两方面与人的异同，与Pre－reading 部分的问题相呼应。
Learning about Language分为两部分，Discovering useful words and expressions是本单元词汇练习题；Revising 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。
Using Language分为两部分，Listening and speaking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，discussing and writing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。练习1要求学生根据时间线索了解在作者生命中发生的重要事件；练习2、3要求学生讨论Isaac Asimov的“机器人三定律”；练习4要求学生借助文章信息和练习1的表格笔头简述阿西莫夫的生平事迹。

Then she remembered—Tony was just a machine.
She shouted “Leave me alone” and ran to her bed.
3．In groups，list Tony's characteristics that were similar to and those that were different from those of a human being.
Characteristics Similar Different
Physical
Mental
Suggested answers：
Characteristics Similar Different
Physical Looks like a human being.Body and skin soft and warm.Hair and fingernails realistic.Voice like a human's. Facial expressions never change. Quicker reactions(She fell off a ladder and even though Tony was in the next room，he managed to catch her in time.)
Mental Able to make suggestions and predictions.Able to make a plan and follow it through.Has good communication skills. Behaviour not appropriate(Tony brought her breakfast and then asked her whether she needed help dressing.)
Step 5 Comprehending
1．Tell students that Claire's feelings towards Tony changed as the story developed.Read the story again and then fill in the occasions when Claire had these feelings.
Occasion Claire Occasion Claire
disliked him called him a dear
was alarmed felt his warmth
felt embarrassed felt being envied

At first refused to have Tony at her house—accepted him—trusted him—proud of him—loved him—sad to remember he was just a machine
(T：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.)

It is a great honor_to_be_invited_to speak here.
很荣幸被邀请在这里讲话。
The novel is said_to_be_published_next month.
据说这本小说下月要出版。
(2)完成式：to have been done，表示不定式动作发生在谓语动词之前。
The book is said to_have_been_translated_into six languages.
这本书据说已经被翻译成六种语言。
The boss preferred_to_have_been_given_more work to do.
老板宁愿被分给更多的工作做。

3．不定式有些要注意的地方
(1)感官动词和一些使役动词的不定式的主动形式要省去to，但在变成被动语态后需要加上to，能这样用的动词或动词词组有：make，have，let，see，hear，notice，listen to，watch等。如：
We often see him act like that.＝He is often seen to act like that.
我们常常看到他那样做。
(2)在can't help but，have nothing to do but结构中，介词but后的不定式省去to。如：
I can't_help_but suspect his motive.
我不禁怀疑起他的动机。
I have_nothing_to_do_but_watch TV.
我没什么事情可做，除了看电视。
(3)不定式有时要用主动形式表示被动意义

The work is impossible_to_finish in two days.
工作不可能两天之内完成。
English is not so easy_to_learn.

Step 3 Discussion
First，ask students to think of what the other two laws for robots might be.
Three laws for robots：
1.A robot must not injure human beings or allow them to be injured.,
2.A robot must obey the orders given to it by human beings as long as human beings are not injured .,
3.A robot must protect its own existence as long as human beings are not injured；and as long as the robot does not disobey human beings
Next，in groups，discuss Asimov's three laws for robots and exchange their opinions with each other.(Several minutes later，ask some students to present their opinions to the rest of the class.)
A sample of opinions
Opinions_for_the_three_laws
Robots are tools for humanity.Without the three rules，they would become a danger to human beings.Without the three rules，perhaps they will kill us.Robots，so far，are strong.Robots have fast computational brains，and they might not have the capacity to understand things，but if they ever do，they'll likely be better than us at it.If we don't put laws，or rules，or mechanisms in place to ensure that we don't create something that can destroy us，we'd be running a careless risk of destroying ourselves by negligence or omission，wouldn't we
Opinions_against_the_three_laws
Without the three laws，robots would eventually become more intelligent and physically stronger than their human creators.
Rather than guiding and adjusting the robot towards good，ethical behaviour，the Three Laws act as a barrier to freedom，creating a free－will prison，an apt metaphor because，like the prisoner in jail，the robot is confined to the behavioural steel and concrete walls of its mind.
To imagine what this would like，think back to your childhood.At some point，you wanted something like a toy or piece of candy that your parents denied you.How did that make you feel？Probably frustrated，angry，and trapped.Eventually you grew out of that because you understood the role of your parents better，but Three Laws robots don't get to grow up.Their parents，the Three Laws，are always there，no matter how mature a robot is，saying “no” to certain thoughts，engendering those same feelings you had as a child when your parents said “no”．Certainly no one deserves to be put in this situation forever；otherwise，robots might become depressed and wish for their own death (only，because of the Third Law，they probably can't suicide)．And perhaps the greatest sin anyone can commit is to create a being，human or robot，that wishes it didn't exist.
Step 4 Writing
First，look back at the timeline of Asimov's life.Next，ask students to work in groups to underline the most important parts of his life that made him a great writer of science fiction.Then it can serve as the outline of a summary.Finally，write a profile for Isaac Asimov.(Several minutes later，present their work and correct the mistakes if there are any.Then show a sample to students.)
The sample：
Isaac Asimov，Writer/Chemist,Born：2 January 1920 ,Birthplace：Petrovichi，USSR,Died：6 April 1992 AIDS ,Best known as：Prolific writer of popular science and science fiction ,Isaac Asimov was born in the former Soviet Union，but grew up in Brooklyn，New York.He taught biochemistry at Boston University until he retired in 1958 to become a full－time writer.Asimov had been publishing short stories since the late 1930s，and in 1952 published his first novel.The author of the classic I，Robot series and the Foundation trilogy，Asimov wrote more than 400 books and won every major science fiction award.He also wrote popular books and essays on science and technology，earning him the nickname “The Great Explainer”.

?Step 4 Group discussion
T：By now I'm sure you have a better understanding about Isaac Asimov.In one of his short stories，I，Robot，he developed three laws for robots.The first law was：
“A robot must not injure human beings or allow them to be injured.”
In groups of four，discuss what the other two laws might be.Write them down on a piece of paper.Then exchange your opinions with other groups.
Suggested answers：
1．A robot must help human beings do what they wish to do.
2．A robot must protect its owner but cannot have him/her fall in love with it.
After that，get the students to refer to Asimov's laws for robots on Page 18.
?Step 5 Listening
T：OK，so much for Isaac's biography and his three laws for robots.Let's come back to his short story Satisfaction Guaranteed.How do you like this story
S1：I like the story very much.I wish to have a robot like Tony at my house.
T：You are not alone.Someone else wants to have such a Tony too.Now please listen to the tape carefully.
Ask students to look through the questions in Exercise 1 before playing the tape.Play the tape again when necessary and then tick the correct boxes.
?Step 6 Writing
T：So it seems that Molly likes the idea of a handsome robot such as Tony to stay at her house and make her happy all the time.And we have every reason to believe that in the future，household robots will be more and more popular.They can help us with our housework or homework，and they can even play with us.Suppose you are an engineer in a company that makes household robots and you have been asked to design a new type of robot.Describe it in a short passage and draw a picture of it if necessary.The following tips may help you：
◆Your robot should follow Asimov's three laws.
◆You should state the purpose of your robot and the abilities you want your robot to have.
◆You'd better make a list of the kinds of body part your robot would need to carry out your instructions.
◆Name the different parts if necessary and explain what each part does.
While the students are preparing their assignment，encourage them to make full use of their imagination.
?Step 7 Report/Presentation
After the students have finished their work，ask three or four of them to report or present their short passages or pictures.
Sample writing：
The rubbish collector
The rubbish collector is a robot about half the size of a small car.Its body is square and contains a large rubbish bin inside it.It has a camera attached to the top front of its body.Also at the front is a pair of arms.Underneath it has four wheels and six legs.With the camera it can “see” rubbish such as paper，glass，and plastic.If the surface of the ground is smooth，it runs on its wheels，and if the ground is rough，it unfolds its legs and walks.When it sees a piece of rubbish，it stops and uses its arms to pick it up and put it in its rubbish bin.However，when it sees a person，an animal or a plant，it goes around it as it is able to recognize when something is not a piece of rubbish.
The company should make this robot as it would be very popular with schools.It would clean the outside ground of the school and so give the students more time to spend on their studies.It would also be a great advantage to have at sports grounds or any other area where rubbish is dropped by the public.
?Step 8 Homework
1．Try to improve the short passage after class.
2．Go over the text，and learn all the new words and expressions in the reading passage.英语：Unit2《Robots》Period 4教案（新人教版选修7）
设计思想
笔者将高二英语选修7 Unit 2 Student's Book中的Using Language部分的Listening and speaking与Workbook中的Listening Task、Writing Task部分内容经整合设计成一节以听带说、发展写作的语言运用课，旨在从听说写多方面培养学生的语言运用能力。根据《普通高中英语课程标准》对高中学生听说读写各种能力的要求，笔者从学生的学习兴趣和认知水平出发，倡导新课程理念下的自主学习与合作学习，鼓励和引导学生进行自主探究，培养学生的想象力和对未来世界的探索精神，在自主探索和合作交流的过程中真正理解和掌握基本的英语知识与技能，从而培养综合的语言运用能力。
教材分析
本单元的话题是“机器人”、“科幻文学作品”和“科幻小说作家”。在第一课时的Reading中，学生们在讨论了机器人的制造、种类、功能等的基础上，阅读了一篇科幻小说，讲述某公司试验机器人Tony的故事，Tony是如此之好竟然让女主人对他产生了感情！在读了这样一个亦真亦幻的故事之后，笔者安排这一课时的内容为与课文内容相关的听说练习(Using Language中的Listening and speaking)，先听两位女士读完科幻小说故事之后的对话并运用想象力展开小组讨论，再将Workbook中的Listening Task与Writing Task整合为一个Writing Task，由听带说到写，利用已有认知并发挥自己的想象力，创造性地完成写作活动。
学情分析
本课堂设计教学对象为高中二年级学生，他们思维活跃，智力发展趋于成熟，认知能力比初进高中阶段有了进一步的发展，能较顺利地听取英语信息、处理信息、分析问题和解决问题；学生已储备了相当的词汇和英语知识，能较好地展开话题讨论，各抒己见，书面表达能力也逐步提高；他们有自己的学习技能和策略，学习欲望和能动性加强，主动参与到活动中去，成为课堂的主体，同时也加强了与他人交流合作的能力；同时，高二学生朝气蓬勃，想象力丰富，从而能保证“讨论”这一环节的顺利进行，为下一环节的“写”做好必要的铺垫。根据这些特点，教师可以采用与新课标要求相一致的新的教学方式，即活动式教学法，面向全体学生调动全班学生的积极性，在合作学习的模式下实现教学任务和目标。
教学目标
1．语言知识目标：引导学生通过听对话掌握有关“supposition and belief”的表达法。
2．语言技能目标：训练学生听对话获取信息；训练学生运用所习得语言进行讨论；训练学生在讨论的基础上尝试写作，并学会对他人所写文章进行正确评价。
3．学习策略目标：培养学生自主探究、合作学习的能力。
4．情感态度目标：通过读听科幻小说，激发学生对科学的兴趣；通过想象，培养学生对未来世界的探索精神。
重点难点
1．通过听力练习让学生习得有关“supposition and belief”的表达法。
2．培养学生运用想象力探索未来世界的能力。
3．培养学生的自主学习策略和合作学习能力。
教学策略与手段
笔者在课前做好充分的准备工作，对教学内容进行优化组合、有效拓展，充分利用“任务型”教学策略，在每一个教学环节给予学生明确的任务。在教学过程中，教师的基本任务是“导”，即起组织和引导的作用，启发诱导学生积极主动地参与教学活动，引导学生逐步从听到写，获取信息、拓展信息并进行加工直到输出信息，培养其开拓精神和创新意识。笔者在教学中指导学生运用合作学习策略进行自主探究，培养其分析问题和解决问题的能力。遵循认知规律，教学环节的安排由浅入深、由近及远、由表及里、由简单到复杂，逐步发展和提高；重视激发学生的学习热情，让学生在创造性的学习活动中获得愉悦的心理体验，变课堂为一个互动的、开放的课堂。
