You will get a refund if you dont see a whale on the tour. T: Now we are going to hear some dialogues between tourists and a tour guide. They have finished the whale watching tour. Look at the aspects in Ex 2. Go through the aspects given and decide which ones the tourists might think were good and which they might complain about. After that, well listen to the tape and check the answers. Clear?Play the tape. For the first time, they are required to check the answers they have chosen. For the second time, they should number the aspects in the order they hear about them. Then check the answers with the whole class.T: We have so many jobs to do today. Now Page 26. Lets listen to the tape again to finish Exx 3-5. For Ex 4, you are required to pick out the expressions about complaint in each of the three dialogues and then complete the sentences given. These expressions are the functional items of this unit.Play the tape again and help the Ss to finish these tasks and at last, check the answers with the class. Step Listening (2)T: Turn to Page 62 please. First look at the three photos. What do you see in them?Ss: Sharks.T: Have you seen any sharks with your own eyes? Where did you see them? How would you like to describe them? S: I saw them in an aquarium. I think they are huge and fierce. S: I saw them on the TV. It is reported that sharks attack people on the beaches in some areas. T: How do you feel when you look at the photos of them?S: I feel scared.S: I feel amazed.S: I feel that humans are so fragile and weak in front of them. Then let the Ss discuss the questions above the photos in groups and make short dialogues. They will share information with each other and learn more about sharks. Possible dialogue 1: Sa: Where have you seen sharks?Sb: Ive seen them at an aquarium. Sa: What do you know about them?Sb: I know from the interpreter that there are many kinds of sharks in the world but just a few of them may attack people. What about you, C?Sc: Ive seen them both on TV and at an aquarium. When I saw them in the large aquarium, I found they were not so big and fierce. On the contrary, they were lively and active. When I saw them on TV programs about the world under the sea, I found they swam very quickly like an arrow. In fact, I like them very much. Do you know anything about shark, A?Sa: Yes. Ive seen them on the Internet, on TV and in the film of Jaws. The animal is a wonderful creature in nature; while in the film it was very cruel and fierce and killed many people. But I dont think the film tells the true stories of sharks. I always think if you dont disturb the wild animals, they wont attack you, either.Possible dialogue 2:Sa: How do you feel when you look at the photos?Sb: In the first and second one, they seem fine. They have a very good shape and they can swim very quickly.Sc: But in the third one it looks very frightening, just like the big shark in the film Jaws. Its terrible. What do you think about them, A?Sa: Sometimes we may hear news that sharks attack people and this may frighten people very much. But people often pay less attention to the fact that many more sharks are killed by people every year and their amount in nature dropped down very quickly.Sb: Yes. People kill far more sharks than sharks do to people. And I know from some books that seldom do the wild animals attack human beings, if people wont disturb them. So people should think seriously what they have done to sharks. For example, whether weve destroyed their surviving environment or whether too much fishing has broken their food chains.T: As we all know, sharks attack people. Now Lets listen to the news reports on shark attacks. Number the places where these attacks happened in the order your hear them. Are you ready?Play the tape twice or more for the Ss to listen and finish Exx 2-3. After that, check the answers with them. Then let the Ss work in groups and discuss the questions in Ex 4.Suggested answers to Q1:Sa: Just now we heard some reports on shark attacks. As to whether people should hunt down and kill sharks, I think that depends on the case. If the shark kills people, like the one in the film Jaws, it should be killed in order to save peoples lives. But we mustnt kill those that never attack people because not all sharks might hurt people. We cant kill the whole family just because one of them killed a person.Sb: I agree. Shark attacks just happen once in a while. In fact, the chances of being bitten by a shark are actually very small. Compared to what people have done to sharks, they are innocent. Imagine that if human beings hadnt disturbed their circumstance or destroyed their food chain or polluted sea water and so on, would that kinds of things happen so often?Sc: Yes. We human beings must reflect on ourselves whether we leave enough space for sea animals, like sharks, to survive in nature. If we want too much from the sea, we must be punished, by animals, by nature or in some other ways. On the other hand, people can take measures to avoid this. For example, not to swim too close to their habitats, leave them enough space; not to fish too much, especially the certain kinds of fish for sharks food; protect the ocean from being polluted to provide good sea environment for all sea animals and mostly, for human beings.Suggested answers to Q2: Sa: I think it matters if many sharks are killed by people. Everyone knows that any species has its own position in nature, saying nothing of sharks, large and important animals. The amount of sharks will make great effect on the sea creature chain, while sea creature chain will affect the ocean, and the ocean will act on the climate straight, and as a result, on human beings. So I think animals, such as sharks, have a very close relation to people. Sb: Yes. It is reported that shark populations are decreasing at a serious rate because of modern fishing technology. On the other hand, with the deepwater condition getting worse by pollution and peoples killing, more and more species are becoming endangered. Sc: As far as I know, up to 200 million sharks are killed each year. This former huge family now has no longer held advantages. Their situation makes us worried. So I think government should make sure that the fishing of sharks is slowed down. Meanwhile, take matures to protect them.T: Very good job! Im very glad to find that you have got strong sense of environmental protection.Now, look at the screen and we will read two pieces of news with pictures. Deal with the new words first.On the screenWhales and dolphins mysteriously strandedUpdated: New words: Tasmania n.塔斯马尼亚; beaching n.海滩; steer v.驾驶,转向; strand vt.搁浅; rescuer n.救助者; survivor n.生还者(1)Alison Joyce and her two-year-son Tyler look bottle-nosed dolphins stranded on Sea Elephant Beach on Tasmanias King Island in Australia November 29, 2004. Over 100 of the mammals mysteriously beached themselves in a mass stranding which was repeated at another beach on the island states south-east coast. More than three-quarters of Australias whale strandings occur in Tasmania.(2)Part of a pod of beached long-finned pilot whales lie dead in the sand at Sea Elephant Beach on Tasmanias King Island, Australia, November 28, 2004. More than 100 whales and dolphins died in two separate beachings in 24 hours on remote Australian islands, leaving rescuers on Monday struggling to steer survivors out to sea and prevent more strandings.After reading the news there may appear a special atmosphere in class among the Ss and they may get a special education as well. The teacher can take the opportunity to make the Ss know deeply the importance of the protecting nature.Step Listening (3) T: Next we are going to listen to an interview with the shark expert Don James. Before you listen, go through the statements in Ex 1 on Page 65 and predict what you will hear in the interview. Then listen and number these statements in the order you hear them. After the Ss have finished reading the statements, play the tape. Then check the order of the statements. Then let the Ss try to answer the questions in Ex 2 in pairs. Play the tape for the second time. Ask the Ss to take some notes while listening. Finally, ask some of them to answer the questions with the help of their notes according to what they hear.Step HomeworkT: Today we have talked about and listened to something about sea animals. Tomorrow well learn more interesting things about them. Please preview the reading passage on Page 24. Now class is over. Goodbye, everyone.Ss: Goodbye, Sir / Madam高考资源网
