Step I Pre-reading

Ask 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 II  Reading

Deal with the reading part.

Scanning

Ask 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 reading

Comprehending questions on Page 12

Ask 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—Claire‘s guests could see 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 like a 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.

Characteristics	Similar	Different
Physical	Tall, handsome, black hair, deep voice	Facial expressions never changed
Mental	Clever enough to solve all kinds of problems	Cannot think for itself
Emotional	love	Never experienced such feelings as embarrassment, alarm, anger, happiness or envy

Claire’s emotion development

After 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 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.

Characteristics of science fiction

T: 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.

Explanation

During 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. Don’t forget to surf the internet to learn more about the great writer and his stories. Of course you will learn more about robots.

Step III   Homework:
