27、 the story?S: Whalers, killer whales and baleen whales. T: But what is the real name of the killers? And how did they help the whalers to catch the baleen whales? Lets read the text and find the answers. Step Reading comprehending In this step, the Ss will read the text and deal with the comprehendi

28、ng exercises. SkimmingLet the Ss skim the text and get the main ideas of the two anecdotes. After skimming.T: Who is Old Tom? What is the first anecdote about?S: Old Tom is the name of killer whales. The first anecdote describes a hunting experience about how the killer whales helped the whalers to

29、hunt a whale. T: Good! How about the second one?S: It tells about how a killer whale protected and saved James, a whaler. ScanningLet the Ss do scanning and find the answers to the questions in Exercise 2. T: First, go through the questions in Exercise 2 on Page 21, and then I will give you several

30、minutes to do scanning. A few minutes later, guide the Ss to do pair work (as follows), while the teacher can walk around to see if they have any problems to deal with. Sa: What evidence was there that Old Tom was helping the whalers out?Sb: Old Tom was swimming by the boat, showing us the way and l

31、eading us to the hunt. George started beating the water with his oar and there was Tom, circling back to the boat, leading us to the hunt again .Then ask some pairs to ask and answer the questions before class.T: Very good! Now close your books and well listen to the tape of this text. Take out a pi

32、ece of paper. Look at the screen, while you are listening, pay attention to the whole story and try to write down the missing words in the sentences according to what you hear. Are you ready? Show the following sentences on the screen. (The sentences are given with blanks.)1. I thought, at the time,

33、 that this was just a story but then I witnessed it with my own eyes many times.2. as I was sorting out my accommodation, I heard a loud noise coming from the bay.3. We ran down to the shore in time to see an enormous animal throwing itself out of the water and then crashing down again.4. “Come on,

34、Clancy. To the boat,” George said as he ran ahead of me.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

35、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 Discussion Dea

36、l 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! Its the head of the killer whale team, I think.S: Maybe it is the most clever and po

37、werful 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. Theyre jus

38、t 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

39、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

40、to the master to report their success. Thats 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

41、 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 HomeworkT: 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. Whats your opinion? Are you for or against the banning whaling? Consider the problem carefully and well have a discussion tomorrow. Good-bye everyone!
