【正文】 know I must work hard. (Adverbial) I’m very excited about being invited to my friend’s birthday party. (Object of prep.) We don’t like being kept writing homework all day long on Sunday. (Object of vt.) Being praised is a pleasure. (Subject) The boy being blamed is crying. (Attribute) Step Ⅱ Listening (1) T: Page 25, please. You will find an advertisement about whale watching tours. Have you ever been on such a tour? What can you experience on this tour? ... Now read it carefully and try to answer the questions above it. You can discuss with your partners. Suggested answers: 1. You can: listen to whales singing and watch them underwater on the videocamera。 witness whales in their natural environment as they leap out of water and feed in our waters。 enjoy plenty of other marine animals such as dolphins, seals and penguins. 2. I am eager to go on this tour. I would like to witness whales in their natural environment as they leap out of water and feed in our waters best. 3. You will get a refund if you don’t 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 plain about. After that, we’ll 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. Let’s listen to the tape again to finish Exx 35. For Ex 4, you are required to pick out the expressions about plaint in each of the three dialogues and then plete 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 Ⅲ 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: I’ve 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: I’ve 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. I’ve seen them on the Inter, 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 don’t think the film tells the true stories of sharks. I always think if you don’t disturb the wild animals, they won’t 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. It’s 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 won’t disturb them. So people should think seriously what they have done to sharks. For example, whether we’ve destroyed their surviving environment or whether too much fishing has broken their food chains. T: As we all know, sharks attack people. Now Let’s 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 23. 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 people’s lives. But we mustn’t kill those that never attack people because not all sharks might hurt people. We can’t 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 hadn’t 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 bei
