And do you like them?Ss: Yes. They are very beautiful and lovely. / Some are ugly and dangerous. / I like them very much whether they are beautiful or ugly. / Yes, they are very nice .T: Mm, I see. But where did you see them?Ss: At an aquarium. / In the tunnel under the sea. / In the zoo. / On TV, the programs about the sea animals. / On the Internet. I have seen a lot of pictures about the sea animals and plants .T: Very good. You see, your sight of sea animals is limited. Do you want to know more about them?Ss: Yes! Very much! But how?T: Now you can talk to each other in pairs about the sea animals and plants youve seen before to enrich your knowledge of them. Use the list on Page 19 to help you. The Ss begin to talk about the plants and animals under the sea theyve seen before and the teacher can walk around to see what they are talking about. After that the teacher can ask two or three pairs to act their dialogues out.Possible dialogue 1:Sa: Last summer holiday, I went to HainanProvince with my parents. There when I was on my snorkelling trip, I saw many kinds of beautiful fish under the sea. They have so rich and fresh colors that I couldnt believe my eyes.Sb: Do you know their names?Sa: No. So large variety of colorful fish that they made me astonished. But I could hardly call a single name of them. Maybe I saw sea anemones, which live on rocks and look like flowers. Sb: Have you seen anything special?Sa: Yes. I saw some corals, real and living corals. You know the red one is the most beautiful.Sb: Red? Ive only seen white ones in decoration shops. I like its fantastic shapes. But I dont know there are some red ones.Sa: Besides red ones, there are purple, yellow, blue, pink ones. Sb: Oh! Thats wonderful! How lucky you are! I like sea animals and plants very much but I havent seen them under the sea with my own eyes. Ive only seen them on TV programs and in some films about living things under the sea.Sa: When we can earn enough money by ourselves, the first holiday trip would be going on a snorkelling trip.Sb: Its a go!Possible dialogue 2:Sa: Once I saw many turtles in the Aquarium of Shanhaiguan. Some were so large that they couldnt move very fast. Two or three of them had hard horns on their legs. It is said they must have lived at least over three hundred years before they have this kind of thing.Sb: Really? Ive never heard about that. I have been to Shengya Ocean World in Dalian. I saw some large turtles but didnt find that kind of ones. Sa: You must have seen many fish, right? Sb: Certainly! A large number of animals and plants under the sea.Sa: Tell me more, please.Sb: Some eels, for example. They were long and thin with sharp teeth and swam very quickly. Small sharks in white-grey color swam in groups around the diver. They were active and seemed never to stop. The explainer told us that only a few kinds of sharks might attack people. There were also fat sea lions, yellow and green parrotfish, blue-striped angelfish, sea horsesthey were very small, floating upright in water, sea stars in many colors and so on. There were also some sea plants such as kelp. Sa: Thats wonderful. Ill ask my parents to take me there next summer holiday!T: Very good job! You make me know more about the lovely sea animals. Would you like me to show you around the world under the sea? Ss: Hurray! We couldnt wait any more!T: But remember, after youve seen each beautiful creature without name marked, you must try to write down the name of the animal or the plant in your exercise books, three of you will be asked to write the names on the blackboard. Whoever writes the names most quickly and accurately will get a small gift. Clear?Show pictures of sea plants and animals on the screen and ask the Ss to do the spelling job. If possible, a short video about the world under sea would be better. T: Arent they beautiful! I think youve known more about sea animals and plants. Now, lets work in groups of four, making a list about what you have known about them to collect the information. Draw a form like this and then fill in it. Show the following form on the screen. After the Ss have finished, show a fulfilled one as a summary.

T: Now look at the picture in Pre-reading. What can you see and what do you think is happening in it?S: In the picture we can see a huge fish, from the water spurted out of the blow-hole on its head we can know it must be a whale. There are some big fish running after it. They are having a fight, I guess. S: There is a small boat not far from the whale. The people on the boat might be hunting whales. I heard of it before. T: If you want to uncover the puzzle, read the words on the left side of the picture. After a short while.T: What does anecdote mean? Have you got its meaning from the dictionary?S: It means a short story based on your personal experience.T: Right! So what are the main characters of 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 comprehending 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 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 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 leading 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 piece 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?
