Unit 15 Were trying to save the manatees!Part 1: Teaching design (第一部分：教学设计)Structures: Review of structuresTarget language: I think that animals should not live in zoos. I disagree with you. I feel that zoos provide clean and safe places for endangered animals to live.Vocabulary: manatee, cheetah, kangaroo, chimpanzee, recycle, aquatic, habitat, gentle, aggressive, playful, furry, gray, enormous, strong, spotted, underwater, mangrove, vegetation, swamp, save, environment, educate, public, politelyLearning strategies: Classifying, Listening for specific informationSection AGoals To review structures learned To listen and talk about animals ProceduresWarming up by learning about animalsAnimals are living things. Plants can make their own food orenergy from the light of the sun, but animals cant do this.Animals have to eat plants or other animals to get energy to live.Some animals eat only plants. We say that these animals are herbivores. Some animals eat onlymeat. We say that these animals are carnivores. Some animals eat both plants and meat. We say that these animals are omnivores. Plants cant move around, but most animals can move around. Animals are divided into groups.1a Looking and describingOn page 118 in the picture you will see a zoo with animals and visitors. Now choose adjectives listed in the box to describe the six animals.African elephantsChimpanzeesKangaroosManateesCheetahsPolar bearsenormousnoisyplayfulgentle,shyspotted,fastFurry,aggressive1b Listening and circlingVictor and Ginny are talking about animals. They are describing them with many different words.Now listen to their talk and circle the words used in 1a to describe the animals.TapescriptBoy: Hey, Ginny. Whats that big, furry animal in the pond?Girl: Its a polar bear, Victor. Theyre kind of aggressive.Boy: Are they? Looks like they really love water.Girl: Uh-huh.Boy: And what do you call those big, gray things in the water?Girl: Theyre called manatees.Boy: What?Girl: Manatees. Theyre very gentle and very shy.Girl: Theyre cheetahs. The cheetah is the fastest animal on earth1c Doing groupworkWe humans are animals, too. So we are like animals in some ways. Now in groups of four, you are going to think of an animal that is the same as you are in some ways. Then you are to describe the animal and the others are to guess its name.A: I am like this animal because I am strong and intelligent. I like water, and I like to eat vegetables.B: Youre like an elephant. A: No. B: Youre like a manatee. A: Yes! A: I am like this animal because I am heavy and enormous. I like forests, and I like to go around the mountain.B: Youre like a chimpanzee. A: No.B: Youre like an elephant. A: Yes!A: I am like this animal because I like spotted clothing and I run the fastest in my school.B: Youre like a manatee. A: No.B: Youre like a cheetahs. A: Yes!2a Listening and matchingA boy is asking a man about animals he likes. TapescriptBoy: Can you tell us about the manatees, please?Man: Sure. Were trying to save them.Boy: Why? Are they endangered?Man: Yes. There used to be a lot of manatees, but now there arent very many of them.Boy: Do you know how many there are?Man: At this point, there are only about 2, 500 in the U.S. In 1927, it was discovered that they were endangered. Since then, the government has passed laws to protect them.Boy: Where do they live? Man: Their favorite habitat is the water under the trees in mangrove swamps.Boy: And why are they endangered?Man: Some of the swamps have become polluted. Also, there sometimes isnt enough food for all of them. As you can see, theyre large. The average manatee is about ten feet long and weighs about 1, 000 pounds. They need about 100 pounds of aquatic feed a day.Boy: Aquatic feed?Man: Oh, thats underwater plants and vegetation. Thats what they eat.Now listen to their talk and match the words with the definitions in the box on page 119. 1. endangered b. there arent very many of them.2. mangrove swamps d. a place where trees grow in water3. habitat a. the place where something lives4. aquatic feed underwater plants and vegetation2b Listening and completingNext you are going to complete the chart on page 119 in the middle. Listen to the talk once more for the necessary information.Kind of animalManateeNumber2,500 in the USHabitatthe water under the trees inmangrove swampsReason why they are endangeredSome of the swamps have become polluted. Also, there sometimes isnt enough food for all of them.descriptionThe average manatee is aboutten feet long and weighs about1, 000 pounds. They needabout 100 pounds of aquatic feed a day.In the end you are going to read the tapescript. While reading, you must try to blacken all the predicates, underline all the expressions and circle all the connectives.2c Doing pairworkYou are going to interview a zoo attendant. Now use the facts from above activities to role play a conversation between you and the attendant.A: How big are manatees?B: Theyre about 10 feet long and they weigh about 1,000 pounds.A: How much do they eat everyday?B: They need about 100 pounds of aquatic feed a day.A: What is Aquatic feed?B: It is underwater plants and vegetation.

They are endangered also because there sometimes isnt enough food for all of them. A: I am sorry to hear that. There used to be a lot of manatees, but now there arent very many of them left, I think.B: You are right. At this point, there are only about 2, 500 in theU.S. A: Are there any laws to protect them.B: Since 1927 laws have been passed protect them.A: Thank you for your information. 3a Reading and underliningTurn to page 120. Disgusted has written a letter to the editor. Now read it to underline the reasons why Disgusted is opposed to zoos. While reading remember to box all the connectives, blacken all the predicates. Thats grammar study. Dear Editor, I am writing to say that I am against building a new zoo in our town. Zoos are terrible places for animals to live. Ive visited a lot of zoos in my life, and I have never seen one I liked or one that was suitable for animals to live in. Just last week, I visited a zoo and couldnt believe what I saw. The animals are kept in tiny cages and can hardly move at all. And they are only given food once a day. Is this a good way for animals to live? I dont think so. SincerelyDisgusted3b Reading and writingA man called Animal Friend wrote a letter to the editor, too. Now read this letter on 120. While reading, underline all the expressions, box all the connectives, and blacken all the predicates. Thats grammar study, too.Dear Editor.I visited our zoo yesterday and I was very surprised to find hardly anyone there. Zoos are very important places. They are like living textbooks for young people. They provide homes for many endangered animals, and help to educate the public about caring for them. If we dont support our zoos, they wont have enough money to take care of so many fine animas. I urge all of your readers to visit our wonderful zoo soon.Sincerely, Animal friend4 DebatingNext we are going to have a new activityto debate.Lets make two teams. Team A is to debate against keeping animals in the zoos, and Team B is to debate for keeping animals in the zoos for protection and education of the people.Useful expressionsI think thatI agree with you.I believe thatI disagree with you.I feel thatI agree withA: I think that animals should not live in the zoos.B: I disagree with you. I feel that zoos provide clean and safe places for endangered animals to live.A: I dont think so.B: A zoo is a place where many different species of animal are kept and usually can be seen by members of the public. A: Why can people go and see the animals in the forest?B: In that case, more harm will be done to the animals.A: Kept in the zoos animals are losing their natural nature of living.B: Most modern zoos are also centers where animals are studied so that more animals in the forest could be saved and protected.A: Some rare animals are dying out. B: Yes, they are. Rare animals could be preserved when they are in danger of dying out. A: You are right in saying that. But I still think that it is not right to put animals in the zoos. They belong to the forest, the river, the sky and the sea. Closing by learning about Brown Eared-pheasant（褐马鸡）To end this period we shall turn our attention to a rare animal found almost only in Shanxi, China, Brown Eared-pheasant, or褐马鸡 in Chinese.This species qualifies as Vulnerable because it may have a small population, and although its numbers within protected areas appear to be stable, elsewhere remaining unprotected and isolated populations are declining (potentially rapidly) through ongoing habitat loss and hunting.SECTION BGoalsTo learn to talk about recyclingTo learn to read about recyclingProceduresWarming up by learning about recyclingRecycling is the reuse of materials that would otherwise be considered waste. Recycled materials can be derived from pre-consumer waste (materials used in manufacturing) or post-consumer waste (materials discarded by the consumer).1a Thinking and rankingIf all animals are endangered, if the earth is endangered, then we are endangered. What can we do to save the endangered animals, the endangered earth, and us human beings?Now go to page 121, to rank the items in the box from the easiest to the most difficult.5 Stop riding in cars4 Recycle books and paper1 Turn off the lights when you leave the room2 Turn off the shower while you are washing your hair3 Dont use paper towels or napkins1b Doing pairworkIn pairs you are going to talk to compare your answers.A: Recycling paper is really easy.B: I agree.

TapescriptBoy: Hey, Julia. Dont forget to turn off the lights. It saves electricity.Girl: Oh, I know. I usually do that. I was just in a hurry. How come youre so interested in the environment, Jack?Boy: I always have been.

Turn to page 122 now. What does the article The house of trash talk about? It tells about Amy Winterbourne. After reading the article, you will go to interview her. So while reading write down five questions you would like to ask her.The house of trashYou have probably never heard of Amy Winterbourne, but she is a most unusual woman. She lives in a house that she built herself out of trash. Well, the stuff used to be called trash, but now its called “recycled” material. The windows and doors came from old buildings around the town that were being pulled down. The walls are made from old glass bottles that are glued together. The roof is made from discarded tiles. And the fence is built out of used soda cans. Amy recently won an award from the Help Save Our Planet Society. The president Jackson Smith said, “Amy is an inspiration to us all.” And what does Amy do in her spare time? She makes model toys out of old TVs, and sells them to raise money for the Childrens Hospital.Questions to be asked of Amy Winterbourne1.What are you, Ms Amy Winterbourne?2.Why did you bui
