1、Period 4Using Language：Listening，Speaking and Writing设计者邵宁宁Teaching aims1Enable students to express supposition and belief.2Learn to write a passage describing a new type of robot.Teaching proceduresStep 1Leadin1First，ask students to look at the words below.Many of them are used to describe Claires

2、feelings in the story.Carry out the following tasks in pairs.alarmedembarrassedamazedawfulamusedsurprisedattracteddisturbedenviedimpressedsatisfiedhurtfrightenedupset(1)Find as many of these words in the text as possible and underline the sentences.(2)Write a short paragraph to describe Claire using

3、 some of these words.(3)Tell a story using at least five of these words.Sample writing：Claire is a very emotional woman who needs a good friend.She finds this friend in a robot called Tony，who comes to help her in her home.She is attracted to him because he is so handsome and sympathetic.He becomes

4、her best friend.She is impressed by his abilities but embarrassed by her feelings for him.She is disturbed because she thinks of him as a man (even though he is not) but is amused that other women envy her and think they are having an affair.Claire succeeds in overcoming her sense of failure，but in

5、doing so falls in love with Tony.His visit leaves her upset，frightened and hurt，which has replaced her sense of failure.She has been hurt by Tony because he is too nice rather than because he is not nice enough.2Next，have a small talk about the story.(1)Why did Tony have to be rebuilt?(2)How would y

6、ou feel if you had a robot like Tony in your house?Suggested answers：(1)Because you cant have women falling in love with machines.(2)Various answers are possible.Students are encouraged to speak out their feelings freely.Step 2Listening1Molly and Kate are discussing the story “Satisfaction Guarantee

9、 Claire feel good about herself？5.Who thinks taking Tony away must have hurt Claire？6.Who said that making a robot so much like a man was bound to cause trouble？2.Next，listen again and find answers to the following questions.(1)What does Kate think the difference between robots and human is?(2)How d

10、oes Kate think Claire was hurting herself?(3)Why would one of the girls like a robot such as Tony living at her house?(4)What does Kate think the companys biggest mistake was?Suggested answers：(1)Robots cant feel emotion of any kind.(2)By seeing herself in a negative way.(3)She likes the idea of a h

11、andsome man whose only purpose was to please her.(4)Making the robot look so much like a real man.3Listen to the tape again and write down the expressions of supposition and belief.Keys：Step 3DiscussionStudents are asked to work in groups and imagine having a robot in their houses to do the housewor

12、k.Discuss what the positive or negative effects of the situation would be.(Dont forget to use expressions of supposition and belief.Students are given five minutes.Five minutes later，ask some students to present their ideas to the whole class.Encourage every student to use his imagination，because th

13、erere no right or wrong answers，only different opinions.After students present their opinions，the teacher speaks out his or her opinion.)A samplePositive_effectsI think it is wonderful for people to have robots in their houses to do the housework.After a days work，when people get home，they can be re

14、ally relaxed with everything prepared by their robots.A robot never gets tired.Nor does it complain.Life will be very easy and comfortable.Negative_effectsMaybe people can enjoy a very comfortable life with the help of their robots.But at the same time I believe people will lose the ability to do ho

15、usework.As time goes by，people cannot live well without a robots help.I think that kind of life would be terrible.Step 4WritingStudents are asked to work in groups.First decide the purpose of the robot，then make a list of the abilities the robot has.Next draw a picture on a piece of paper and name i

16、ts parts and explain what each part does.Finally write a passage describing the robot and what it can do.Show the following to help students to design their robots.Tips on designing your robotsFor each robot that you build，you will have to choose options for six major robot characteristics.Each char

17、acteristic gives rise to one or more questions.These are：Looks：What does the robot look like？Is there a reason for it to look as it does？Sensing：How does the robot “know” or figure out whats in its environment？If it were put in a different environment，would it be able to figure out this new environm

18、ent？Movement：How does the robot move within its environment？If it were put in a different environment，would it still be able to move within this new space？Manipulation：How does the robot move or manipulate other objects within its environment？Can a single robot move or manipulate more than one kind

19、of object？Energy：How is the robot powered？Can it have more than one energy source？Intelligence：How does the robot “think”？What does it mean to say that a robot “thinks”？Note：Not all robots have to have all six characteristics.For example，some robots dont need to manipulate things，so they have no man

20、ipulating characteristics.Some robots have more than one manifestation of a characteristic.For example，a robot may be able to sense its environment using both a vision system and sonar.Students are asked to discuss first.If there is not enough time，they should finfish it after class.Step 5HomeworkWr

21、ite a passage describing a new type of robot.Sample writing：Remote Presence RobotsRemote Presence Robots allow a medical expert to visually examine and communicate with a patient from anywhere in the world，via the machine，using wireless technology.The robot runs on a wireless system with the doctor

22、at another location.It is controlled via a secure broadband Internet connection.The doctor (controller) and patient are able to have a realtime twoway audiovisual interaction，with the controller in full command of the robots movements，head monitor and camera.The doctor “driving” the robot can view t

23、he patient，ask questions and read patient records，view Xrays and test results from the console.The patient sees the doctors image on the robots “face”Although the robot does not physically examine the patient，it allows facetoface contact between the doctor and patient，providing immediate access to s

24、pecialists.Our robots certainly would never replace all doctors on ward rounds，but they are a communication tool which allows doctors to have direct contact with their patients if they are unable to get to them.And this may be a significant step for patient care.The rubbish collector robotThe rubbis

25、h 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 pa

26、per，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 goe

27、s 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 grounds of the school and so give the students more time to spend on their studies.It would also be a great advantage

28、 to have at sports grounds or any other area where rubbish is dropped by the public.SDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSFDSFDTRTRTETRRETRET57868767567UIYHUG6675FUGFUSDFSFDSF
