5. As we drew closer, I could see a whale being attacked by a pack of about six other killers.
6. And those others are stopping it diving or fleeing out to sea.
7. Within a moment or two, its body was dragged swiftly by the killers down into the depths of the sea.
8. In the meantime, Old Tom, and the others are having a good feed on its lips and tongue.
After playing the tape, ask someone to spell out the words or write them down on the Bb to check their listening and spelling tasks. At last, show the answers on the screen.
Step Ⅳ Discussion
Deal with Exercise 3 in Comprehending. Let the Ss work in groups and do some discussion.
T: Look at the title of this text: Old Tom the Killer Whale. Who is Old Tom and what is special about it?
S: It is a killer whale! It’s the head of the killer whale team, I think. S: Maybe it is the most clever and powerful one in the team.
T: Now in groups, discuss the relationship between Old Tom and the whalers. Then discuss what other animals help out humans in hunting. A sample description:
Sa: Old Tom is honest and helpful to the whalers and the whalers are very kind to Old Tom and its group, too. They’re just like good friends.
Sb: I think so. Maybe Old Tom and other killers have been trained by the whalers, just like hunting dogs, they get on well with the whalers. In everyday life they take care of each other and in an emergency, they help each other.
Sc: Speaking to hunting dogs, I think they are the most typical animals that help out humans in hunting. Upon meeting the quarries, they are very excited and listen to their masters very well to hunt for them. If there is a group of dogs, they may work together till they help the master catch the quarries. Then they will be very happy and come back to the master to report their success. That’s very interesting. And if their
master is in danger, they will rush up to rescue him. There are many moving stories of this kind.
Sd: Yes. After reading the text, we can learn more about the relationship between humans and animals. Humans and animals should depend on each other and be kind to each other. Only in that way, can the world be more harmonious and beautiful. Deal with some language points.
Step Ⅴ Homework
T: As a matter of fact, whales are now an endangered animal. Many people are trying to protect them from being hunted. The last whaling station in Australia closed in 1978. But some countries oppose the ban. And there are still people who hunt whales. What’s your opinion? Are you for or against the banning whaling? Consider the problem carefully and we’ll have a discussion tomorrow. Good-bye everyone!

StepⅠ Revision
T: Good morning / afternoon everyone! Ss: Good morning / afternoon, Sir / Madam!
T: At the end of last period, you were asked to think about the international ban on whaling. Are you for it or against it? Now let’s work in groups of four and discuss the reasons for and against banning whaling.
While the Ss are having discussion, walk around to see if they are getting on well with the job. When they have finished, ask the Ss to speak out their group’s opinions and reasons.
Possible discussion:
Sa: I think it’s important to protect whales. After a long time hunting, the number of whales has largely decreased. On the other hand, with the development of industry, the sea has been seriously polluted and the pollution has killed many whales. Sb: Yes. I agree on the international ban. Whale is one of the oldest species on the earth. Protecting them effectively and studying them seriously will bring human beings great benefit.
Sc: Whales are the hugest animals living in the ocean. The number of them in nature will have great effect on the balance of sea animals as well as nature.
Sd: We seem to have the same idea about the topic and I agree with you all. Firstly, animals are human being’s friends; we must try to protect them, especially those
endangered. It is reported that many whales kill themselves for some unknown reasons on some beaches every year. Maybe that is caused by pollution. In a word, man has done much harm to whales. It’s time for us humans to do something to protect them. No more whaling!
T: Yes, no more whaling! I agree with you very much! I hope you can get more information about whales after class to learn more about their current situation.
Step Ⅱ Language study
Deal with the useful words and expressions in this unit and let the Ss do some exercises to master their meanings and usages. T: Turn to Pages 22, please finish Exx 1 -3.
When the Ss have finished that, check the answers with the whole class. T: Now, we’ll revise some useful structures.
As the teacher explains the grammar, he / she will show the slides at proper time.
Step Ⅲ Practice (Workbook exercises)
Let the Ss finish the exercises in USING WORDS AND EXPRESSIONS on Page 63 to further practice the use of some key words and expressions.
Then let them finish the exercises in USING STRUCTURES. After students have finished, show some students’ work on the projector, check their work with the whole class. Correct the errors if there are any.
This structure is used after prepositions and verbs normally followed by -ing form. So the teacher can help the Ss summarize the verbs or phrasal verbs followed by -ing form.
Step Ⅳ Homework Homework for today:
