Step Ⅱ Free-talk and Lead-in
T: Do you like reading novels?
Ss: Yes.
T: What kind of novel do you like best?
S1: I like reading detective novels.
T: Why do you like novels of this kind?
S1: Because this kind of novel is full of suspension and the end of it is often surprising.
T: Very good. Does anyone have a different opinion?
S2:I enjoy reading about science fiction.
T: Tell us why, please.
S2:Science fiction is often about the things that may be possible in the far future. It can help us develop our minds and imagination.
T:A good job. Sit down, please. Today we’re going to talk about science fiction.
(Bb: Unit 12 Fact and fantasy)
Step Ⅲ Warming up
T:OK. Now, look at the covers of the two books written by Jules Verne.(The multimedia shows the two books.)
T: Have you read them?
(Some say “Yes”,while some say “No”.Teacher asks two students who say “Yes” to stand up and say something they know about the books.)
S3:I have read the book “20 000 Leagues under the sea”.It mainly tells us a story in which Dr Aronnax, his servant and a Canadian whale hunter were kept as prisoners by Captain Nemo and then went on a voyage across the oceans by the Nautilus.
S4:The book “Journey to the Centre of the Earth” describes what two men experienced after entering the centre of the earth through a chimney in an extinct volcano, which lies in Ireland.
T: You’re wonderful! Have you read any of his books besides these two books? What are they about?
S5:I have heard of his book “Around the World in 80 Days”,but I haven’t read it. So I don’t know what it is about.
T: It doesn’t matter. If you’re interested in it, you can go to the library or surf the Internet to read it after class. Jules Verne lived between 1828 and 1905,so there were many scientific facts that he didn’t know or guess. Do you know the following facts? Now,let’s have a quiz to see if you know any better.
(Teacher uses the multimedia to show the following.)
1.What is the highest mountain on earth and how high it is?
2.What is the deepest point in the ocean and where is it?
3.Which is the longest river on earth and how long is it?
4.What is the distance from the earth to the moon? 5.How far is it to the centre of the earth?
6.How high are the temperatures near the centre of the earth?
7.What is the longest distance around the world?
8.How fast does a balloon travel?How about an aeroplane?How about a space shuttle?
T: Now, I’ll give you five minutes to write your answers on a piece of paper. After a while, you can check your answers with the screen and tell me how many points you get.(Five minutes later)Time is up. Have you finished?
Ss: Yes.
T: Now check your answers. (Show the answers on the screen.)
Step Ⅳ Listening
T: So much for Warming up. Now, let’s do some listening. Look at the listening part on Page 9.Listen to the tape and write down where, when and what Sam and Betty saw. Then according to the description you hear on the tape, make a sketch of the animal. Are you clear about that?
Ss: Yes.
T: Now, let’s listen to the tape carefully and finish the task.
(Teacher plays the tape for the students to listen. Then give the students a few minutes to fill in the chart and make a sketch of the animal as they saw. When they finish, teacher checks their answers and picks out one sketch of the animal drawn vividly by them as an example.)
T: OK. Let’s go on with the listening practice. Listen to the tape again and then finish Exercise 2.Before listening to the tape, you need to go through the questions and know what to do.(After a little while.)Are you ready?
Ss: Yes.
(Teacher begins to play the tape for the second time. During this time, teacher may pause for the students to write down the answers to the questions. At last, check the answers with the whole class.)
T: Now, write down five possible questions that other people may later ask Sam, Betty and Karen. First discuss in pairs and then write down your answers when you’ve finished. Exchange your questions with other groups.
(Students do as the teacher says.)
Step Ⅴ Speaking
T: As we know, science fiction is often about things we believe may be possible in the far future, maybe a hundred years later. For example, space travel may be possible in the near future. Because Yang Liwei went on a 17-hour travel to space by Shenzhou Ⅴ spaceship last year. But sometimes people doubt whether science fiction may come true. Do you agree with me?
Ss: Yes.
T: Now, open your books and turn to Page 10.Let’s look at the Speaking part. There are four dialogues about such topics, which are incomplete. Work in pairs to create dialogues. When you’re making the dialogue, you can use the expressions on the blackboard. (Teacher writes the following on the blackboard.)
I believe… I suppose… I doubt…
I’m(not) certain… I can’t imagine… It could be…but…
It’s likely… It would like… I’m sure that…
T :Now, look at the blackboard. The useful expressions are used to express beliefs and doubts. They’re helpful for you to create the dialogues. I’ll give you a few minutes to do them. After a while, I will ask some groups to act out your dialogues. Each group should choose a topic you’re interested in. Is that clear?
Ss: Yes.
T: OK. You can begin.
(Teacher goes among the students while they’re making their dialogues. It necessary, teacher may give them some advice.)
T:(A few minutes later) Are you ready?
Ss: Yes.
T: OK. Which group would like to act out your dialogue?
(Two students stand up and act out their dialogue before the class.)
T: Thank you for your good performance. Please go back to your seats. Which group has made a different dialogue?
(Another two students stand up and their topic is about life in 3098.)
(Teacher at least asks four groups to act out their dialogues before the class, and their topics should be different from each other’s.)
Step Ⅵ Summary and Homework
T: In this class, we’ve talked about science fiction and done some listening and speaking practice. When talking about science fiction, we have done a science quiz to help us learn more about some scientific facts. In the speaking part, we’ve learnt to express our beliefs and doubts freely by making dialogues. Besides, we have also talked about an imaginative dream in the practice part. After class, according to what you’ve said in class, make a dialogue using the useful expressions on the blackboard. At last, don’t forget to prepare for the next period. That’s all for today. See you tomorrow.

T: Well. Now, please look at Exercise 4.In Jules Verne’s times, the knowledge about the earth was very limited, and many scientific facts couldn’t be explained by people. But Jules Verne contained a lot of knowledge about the earth in his novel. Where do you think he might have got his ideas from? You can use all the knowledge you have learnt to explain the questions. Work in groups of four to have a discussion.
(After a while, teacher checks their answers. Students may have various answers.)
T: OK. Let’s go on with the exercises in Post-reading. Under water travel and space travel have many things in common. Do you know the differences and similarities between them? Work in groups of four to finish the chart of Exercise 3.
Suggested answers:
Differences SUBMARINE SPACESHIP
Speed slow fast
Landscape under water landscape space landscape
Number for people a lot of people a few people
Food common food special space food
Clothes diving suits space suits
Similarities Demand for skills is high.

Step Ⅱ Lead-in and Discussion
T:(Teacher shows the following on the screen.)Let’s do an exercise now. Look at the sentences on the screen. Please fill in the blank of each sentence with a suitable word according to the word given in the bracket.
Complete the following sentences:
1.These gold rings are ______ while those glass ones are ______(value).
2.We all like the report given by the famous scientist yesterday. It is ______(encourage).

7.At the beginning the Blacks in the US had no right to vote. It was ______(fair).
8.That plan was a waste of money. We ______(agree) with it.
(Teacher goes into the students and has a discussion with them. After a few minutes.)
T: Have you finished?(Ss: Yes.)Now give us your answers please. Volunteer! One student, one answer.
S1:In the first sentence, we should fill “valuable and valueless” in the blanks according to the meaning of the sentence. Am I right?
Ss: Yes, you are right.
S2:The second answer is “encouraging”,I think.
S3:I’ll try the third sentence. I think “dress” and “undress” should be filled in.
S4:The fourth. It is the word “selfishness” that is suitable for this sentence. Am I right?
S5:I can’t agree with you. Here an adjective is needed.“Selfish” is right in this sentence, I believe.
T: Which is right,S4or S5?
S6:I think S5 is right. A word ending with “-ness” is a noun, not an adjective.
T: Is he right?
Ss: Yes, he is right.
T: Please go on!
…
Suggested answers:
5.Unselfishness
6.careless;careful
7.unfair
8.disagreed
Step Ⅲ Further Discussion
T: Do you like the exercise?(Ss: Yes.)Just now we reviewed a method of word formation. I’m glad you like it. There are four methods of word formation. The first is Clipping or Shortening. For example, telephone→phone; examination→exam; refrigerator→fridge; television→TV; the Chinese Communist Party→CCP etc. Who can give us some other examples?
S7:aeroplane→plane; bicycle→bike; mathematics→maths; very important person→VIP; the United States of America→the US.
S8:photograph→photo; laboratory→lab;October→Oct.; November→Nov.; United Nations→UN
T: So much for this. Now I’ll tell you that the second method of word formation is common.It is conversion.(Show the following on the screen.)Look at the sentences on the screen.Who can tell us the difference between the underlined words in each group of sentences?
Compare the following sentences:
1.a.It has not much taste.
b. The bread tastes delicious.
2.a.They had a quarrel yesterday.
b. They quarrelled for half an hour last night.
3.a.I’ve got an interview with National Chemicals.
b. We interviewed 20 people for the job.
S9:In each group of the sentences, the words underlined belong to the different part of speech. The word in the first sentence is a noun while the other is a verb.
T: That’s right. This method of word formation, Conversion, is to use a form that represents one part of speech as another part of speech without changing the form of the word. The process of creating new words without adding any affixes is also called zero-derivation
Step Ⅴ Test
T: Now let’s have a test.(Show the following on the screen.)Please write your answers on a piece of paper. A few minutes later, we’ll check the answers.
Can you tell us the meaning of the underlined word in each sentence?T ry to guess them.

Ss: Good-bye!
