Ⅵ. Teaching procedures 教學過程

Period 1

1. PRESENTATION & REVISION

Talk about the teaching plan for this unit and at the same time tell the students the teaching aims and demands. During this period, do WARMING-UP, LISTENING, SPEAKING.

2. WARMING-UP

Introduction The pictures and questions: give the students some examples of issues and questions related to the theme of the unit: protecting the environment and wildlife.

Instruction Ask the students to think of other endangered animals and list reasons for their endangerment. Compare the lists with the examples in the pictures and try to find common factors that cause animals to become endangered. Encourage the students to think about ways that humans and animals can help each other and live together in peace.

Extension Ask the students to imagine what the world would be like if another animal, e.g. the lion or the dolphin, was as powerful and dominant as humans are today. How would they treat humans?

Possible answers:

1 Various answers are possible. Other endangered animals include the African elephant, the Asian elephant, the blue whale, the gorilla, the snow leopard (eastern Asia) and the black rhino. There are also several endangered birds, fishes, and other animals. Animals and plants become endangered if their habitat is destroyed or changed, if new species arrive and if a species is overused / hunted. Other factors include disease and pollution.

2 If animals and plants die out, we will not be able to survive. All animals and plants have specific functions and are necessary if we want healthy ecosystems. We need the animals and plants for medical and commercial purposes. We also have a moral responsibility to make sure that we do not cause other animals to die out because of our dominance on the planet.

3 Various answers are possible. We can help endangered animals by protecting their habitats, creating new habitats, protecting the environment (by recycling and reusing), controlling export and import of animals and plants and by learning more about animals and the environment.

3. LISTENING

Introduction The students will hear about the causes and effects of various types of pollution. When the students have listed the causes and effects, they are asked to try to come up with solutions.

Instruction Let the students work in pairs and give them time to get started. If a pair is struggling to get going, you can ask them a few helpful questions. Keep in mind that there are no set answers here, so avoid "giving" answers. Try to encourage the students to think and come up with their own answers. When talking to the pairs, it is good to "talk through" one possible solution to show the students how they can think. E.g.

T: Well, let's think about air pollution. Where does air pollution come from?

S: Cars.

T: Right, cars. Now, if we have too many cars, there will be a lot of air pollution. One way to solve the problem might be to try not to use too many cars. Well, why do people use cars?

S: To go to work.

T: Are there other ways people can get to work?

S: They could take buses or ride a bicycle.

T: OK, so one solution would be to try to get people to take the bus or ride a bicycle.

LISTENING TEXT:

1 Walk along the streets of any major city and you will see that the air you breathe is not very fresh. Air pollution is a serious problem in many of the world's big cities. It is caused by cars and factories. We also pollute the air when we bum oil or coal for energy and heat.

2 Oh my, look at this! Dead fish everywhere! What happened? We used to be able to drink the water in our rivers and lakes, but today, many rivers and lakes have been so polluted that the water is useless. Factories and drainage are polluting the water and we are not taking good care of our water. We use too much water and we waste water. What is more, we pollute water.

3 This beautiful mountain is one of the most popular places for people to visit during holidays and festivals. Thousands of people come here to hike in the mountain's forests and valleys. Unfortunately, the tourists leave a lot of rubbish behind. Plastic bags, soda bottles and other things are thrown everywhere. Many tourists also pick flowers and damage the trees, and the many hotels and restaurants being built are having a negative effect on the environment, too.

Answers to the exercises:

1

What kind of pollution is it? Air pollution Water pollution Waste pollution

Rubbish / trash

What are the causes? Cars, factories, burning

coal and oil Factories and drainage Tourists / people

What are the effects? Various answers are possible. We can't use / drink the water that is polluted. Making the environment ugly, dirty and even dangerous.

2 Various answers are possible.

Air pollution We can make cars that don't pollute the environment. We can ask companies to use modem, clean technology. We can limit the number of cars in our cities. If people get sick from air pollution, we must help them.

Water pollution We can try to use less water and make sure that we do not pollute the water. We can tell factories that they are not allowed to pour waste into lakes and rivers. We can clean the water in our rivers and lakes.

Rubbish We should not throw rubbish in parks and cities. We should not buy things that use a lot of packaging. We can pick up rubbish if we see it. We can put more rubbish bins in our parks and cities.

Extension Ask the students to think of more environmental problems, their causes and effects, and solutions. You can also talk about primary and secondary causes and effects, using a chain mind map.

Secondary cause

Modem life-style, advertisements, people use cars to go to work, etc Primary cause

Too many cars Problem

Air pollution Primary effect

People get sick Secondary effect

Environmental

damage

If possible, the students should try to use the expressions in the Student's Book. If this is too difficult, the students can start by thinking of causes and effects and then try to use the expressions in pairs or groups. Help the students by giving a few examples if necessary.

1 Why can't we drink the water in our rivers and lakes? Because the water is polluted.

2 Since people throw so much rubbish in our parks, the parks are ugly and dangerous.

3 Because of water pollution, we can't use / drink the water in our rivers and lakes. / We can't use / drink the water in our rivers and lakes because of water pollution.

4 If tourists / people throw trash / rubbish in our parks, then the parks will be ugly and even dangerous.

5 Cars and factories cause air pollution. As a result of air pollution, many people get sick.

6 People get sick because of air pollution. It follows that we must do something about it.

7 Throwing trash I rubbish in a park will make the park ugly and dangerous. It follows that we should throw the trash / rubbish in a trash / rubbish bin.

8 Burning coal and oil is bad for the environment. It will lead to air pollution.

4. SPEAKING

Introduction In this pair-work activity, students will use an interview format to practise talking about animals and animal protection.

Note The pictures on SB page 66 show different animals that the students can choose from when they interview each other. The students can also use the pictures for the reading and the pre-reading questions by finding more information about the animals and bringing the information to class.

Instruction Ask the students to work in pairs. One student will be the reporter and should prepare questions for the interview. The other student will be the animal and prepare answers. When both students are ready, they interview each other in pairs and take turns being the reporter and the animal. When the pairs have finished, you can ask one or two pairs to repeat their interview in front of the class.

Extension Ask the students to work in pairs and groups and write down some basic rights for animals.

Sample dialogue:

R: Good morning, Mr. Tiger. My name is Jim and I'm a reporter from China Daily. Uh, I am a little nervous, this is the first time I speak to a tiger. May I ask you some questions?

T: Sure. And don't be nervous, I won't eat you. Ha ha!

R: Urn, right, good... Now, how long have you been living in the zoo?

T: Oh, I came here, let me see, six years ago. I used to live in a forest, but people there cut down all the trees and I had to move. There were cities and people everywhere, so I had no place to go. The police came and took me to the zoo.

R: Do you like living in the zoo?

T: Well, it's not as good as being free, that's for sure. But at least I have food and friends.

R: I see. If you could say something to all the humans in the world, what would you tell them?

T: I would tell them to stop being so selfish. We all need each other and we should try to be friends. If people cut down. trees and pollute the environment to make money, we will all suffer. And don't kill animals to make clothes - when I see people wearing animal furs at the zoo I get really angry.

R: Thank you. Urn, would you please take your paw off my shoulder? It hurts.

T: I'm sorry. I guess I got a bit excited. Don't get me wrong. I like humans. I just wish they would be less selfish.

R: Thank you, Mr. Tiger.

5. SUMMARY & HOMEWORK

1. Preview the reading text

2. Learn the new words and expressions by heart.

3. Get ready to be examined in the speaking activities.

Period 2

1. PRESENTATION & REVISION

1. Ask some pairs to act out the speaking activities.

2. During this period, do some reading.

2. PRE-READING

Introduction The questions are designed to get the students to think about the relationship between humans and the plants and animals around us.

Instruction Encourage answers and comments that help students think about the way Qumans and wildlife interact with each other and depend on each other. Tell the student to work in groups and give each group one of the four questions and ask them to discuss the question without using the book. Allow about five minutes for discussion. Make sure that each group member is given a chance to speak. Ask one student from each group to report in front of the class. Encourage students from other groups to ask questions about the report.

Answers:

1 Various answers are possible. Animals and plants live together in an ecosystem where each species has a specific function. Animals and plants "help" each other in different ways: some plants become homes for animals, and the animals may in turn help the plants by protecting them or adding nutrients; animals eat the plants; animals help the plants reproduce.

2 Various answers are possible. Humans have basic needs such as food and shelter, but we also have social and spiritual needs (we need friends and family, etc).

3 Various answers are possible. Encourage the students to compare animals and humans. Animals and plants also have basic needs and animals live in social groups.

4 Various answers are possible. Animals adapt to changes in their habitat and try to learn to survive when the conditions of their habitat change.

Extension 1 Ask the students to make a list of how human activities affect the plants and animals around us.

Extension 2 Ask the students if they know any stories about animals that are good friends to people.

3. READING

ARE WE ENDANGERED?

Introduction The reading stresses the fact that the way we live is threatening animals, plants, and our planet. We are all responsible for the future of the earth and we must learn to think and act more carefully. If we continue to endanger animals and destroy the environment, we have no future. Many environmentalists use the slogan Think globally, act locally to encourage people to do what they can to help. There are many small things we can do that will make a big difference.

Note that the names Steve Jones and Green Park are fictional.

Summary

1 An environmental expert says that the way we are treating animals and the environment is threatening our existence - by endangering other animals and plants we may ourselves become endangered.

2 A species can become endangered if its habitat is destroyed or changed. Most species are able to adapt to small changes, but if the changes are too/ large or sudden, a species may become endangered.

3 We can help by learning more about the environment, by expanding and protecting habitats, and by reducing pollution.

Instruction Tell the students to read through the text once, marking any new words that they can't guess from the context. Remind them that quite a number of words are explained or defined in the text, e.g. habitat, adapt to, be used to, die out, take measures, original, etc.

Teaching the text The structure and function of a text can help the students understand a text better. Ask the students to reread the second paragraph of Are we endangered? and ask them to change each sentence into a question.

Example:

Sentence Question

A species can become endangered for different reasons. Why does a species become endangered?

When the habitat of a species is changed or destroyed,

the animal or plant has to either adapt to the change or

find a new home. What happens if the habitat of a species is changed or destroyed?

When the students have written down all the questions, tell them to use the same questions to ask about another topic. You can help them by showing a few fill-in-the-blank questions, e.g. Why does ______________________? and What happens if __________________________?

Let the students choose their own topics, but try to get them to stay within the unit's general area. When the students have written the new questions, ask them to answer the questions and use the answers to write a paragraph of their own. Ask the students to compare their paragraph to other students' paragraphs and to the text and let the students discuss differences and similarities. You may also want to ask them how they could use this strategy to deal with other texts.

Tell the students to look at the three questions in post-reading exercise 1. They may answer the questions individually, in pairs or groups, or as a class. Encourage the students to use their own words in their answers.

4. POST-READING

Answers to the exercises:

1 1 Animals and plants become endangered when their habitat is destroyed or when conditions in the habitat change too quickly or too drastically. The text lists three main reasons: habitat change, the arrival of new species in the habitat, and the overuse of the species itself or the resources in the habitat.

2 Various answers are possible. Encourage the students to think of human behaviour that can cause problems: pollution, land use, hunting, farming, etc.

3 Use question 2 as a starting point for the discussion. Look at the behaviour listed in question 2. and think about ways we can change that behaviour. Students may also want to think of ways we can repair the damage we have already done, e.g. clean up the environment, create new habitats, etc.

2 Let the students discuss what they can do and write a list of things to do. Compare with lists from other groups and discuss the effects of the students' ideas.

4. GRAMMAR

Summary of Direct and Indirect Speech:

Indirect Speech is sometimes called Report Structures. If you use Direct Speech, you are repeating the speaker's exact words. If you use Indirect Speech, you are using your own words. Report structures usually contain two clauses.. The main clause contains a reporting verb such as say, tell, ask, etc. The reported clause contains the information that you are reporting. The reported clause can be a that-clause, an if-clause, or a wh-word clause. For reported commands, orders and requests, infinitives are used.

3. INTEGRATING SKILLS

Reading and writing

Introduction The reading introduces the principle reduce, reuse, recycle, and respond and the questions encourage the students. to think of more things we .can do.

Instruction The students can work in pairs or groups to think about what we can do to protect the environment. Any suggestion or idea is worth thinking about, so try to encourage the students to come up with their own ideas. The point of the exercise is to let the students think, read, talk, and write about the environment and causes and effects - there are no correct answers to the exercise. If the students find it difficult to get started, it may be helpful to give an example. As with all examples, it is important to show the reasoning behind the example; the thinking is more important than the example in itself.

One way to encourage and help the students is to ask them questions. For example, if the students are thinking about ways to reduce waste, they can start by looking at the examples in the text. What do they have in common? Why are they useful or effective? Are there similar things we could do? Questions like these may help the students get a better idea of what kind of actions would be useful. It may also help to ask the students to think of specific examples of the actions listed, e.g. for "buy things that use less packaging," ask students to think of things they buy and how much packaging is used. This type of questioning will help students think about the actions in "practical" terms, which may be helpful when they try to think of more things that can be done.

Compare different answers from the groups and ask the students why they think their ideas would work. Elicit as many reasons as possible and encourage debate and discussion. Try to use the responses to challenge and encourage the students: if a student seems very comfortable using the structures and finds it easy to give reasons etc, the teacher should follow up by challenging the idea and/or ask for details, examples, and consequences. If the student seems less comfortable, it may be enough to follow up with" easier" questions or simply a recast or summary. Recasts and summaries are, however, not very effective, so it is always better to try to have a few "easy" follow-up questions in mind for these students.

Writing

Introduction The writing activity is a continuation of the discussion activity above. Since the activity requires some research, it is necessary to give the students time to prepare in class or at home. If it is done as homework, make sure that it isn't too time-consuming or difficult. If each group can decide on a topic in class, the individual group members can be asked to simply bring one page of information to the next class meeting. It is better to do the writing '(including pre-writing) in class, so the students can bring "raw" information, i.e. a photocopy or printout will do.

Instruction In class, the groups will use the information they bring to make a poster. Help the students by using an outline or a sample poster, but make sure that the students are free to do their own thinking and use their own ideas. The tips and guidelines in the book can be used to "revise" the posters.

The students will work in pairs or groups to research, create, and present their posters. Help the students plan their research by suggesting useful resources. You can use the score card below to assess the students (the oral presentation part can be omitted).

Task Score Criteria\

Information 10 The students found and used information that was interesting and accurate.

5 The students used some information, but they could improve the poster by adding more information.

1 The students did not find any information at all.

Presentation 10 The students had prepared an excellent presentation and were able to ask and answer questions about their topic.

5 The students had prepared the presentation and could answer some questions about their topic.

1 The students had not prepared for the presentation.

Posters 10 The students worked together to create a poster that is attractive and easy to understand.

5 Most of the students helped make the poster. The poster is relatively easy to understand, but too simple and sometimes confusing.

I Only one or two students worked on the poster. The poster is confusing and does not contain enough information.

A good poster should be attractive and informative. The information used should be accurate and appropriate and should be presented in a clear and interesting way. Encourage the students to use multiple sources, to try different formats, and to use pictures and illustrations.

CHECKPOINT

Suggested answers to Checkpoint 10:

1 many of the earth's plants and animals have died out.

2 if there was a lot we could do to help protect the environment.

3 what we could do to keep animals and plants from being endangered.

4 to explain it in a simple way.

5 not to pollute the environment.

6 we are not alone in the world.

2. LISTENING

Instruction Ask the students if they know about Darwin's theory of evolution and the idea of survival of the fittest. Ask them to think of examples of the principle. Tell the students that they will hear someone talk about the principle. Ask them to fill in the information.

LISTENING TEXT:

Charles Darwin's famous Theory of Evolution tells us about survival of the fittest. Survival of the fittest means that strong animals survive and weak animals die out. Today, many people are worried about endangered species. But isn't it just normal for some animals to die out?

The situation today is different from that of the past. In the past, animals died out over a long period of time. When animals died out in the past, it was usually because of changes in the weather or other natural causes.

What is happening today is totally different. We are killing millions of species in a short time. The result is that we are killing our future, because so many species are being killed in such a short time that even the fittest can't survive. In fact, there won't be enough species to choose from. Without enough animals and plants, evolution cannot function and nature will get worse instead of better.

Many of the species that are disappearing are unknown and few people even know that they are dying out. These animals and plants have been here long before us and we have no right to kill them. We may also need these species in the future. We must try to keep the endangered species alive. If we allow these species to die out, we are in fact becoming endangered ourselves.

Answers to the exercises:

1 Darwin's Theory of Evolution

Survival of the fittest means strong animals survive, weak animals die.

People are worried about endangered species.

Situation in the past: Animals died out over a long period of time.

Situation Today: We are killing millions of species in a short time.

2 Various answers are possible. Make sure that the students understand the argument on the tape, i.e. that the process of evolution may not function if we kill so many animals in such a short time. We may be doing harm to the process of evolution by endangering or killing the wrong species. Human beings are changing nature so fast that there is no time for evolution to function.

3. TALKING

Instruction Make sure that the students understand the situation and the task. Give them time to prepare the role cards and provide assistance or model as needed. When the students have completed the cards, remind them of the ground rules for discussion and let them start the discussion.

Sample Dialogue:

A: Good morning. I'm a dolphin. I think that I'm man's best friend, because I can help humans do many things. For example, I can help humans learn more about swimming and I can help them look for things in the ocean. I'm also a good friend because I can make humans feel happy and laugh. Many humans like to watch me jump and dive, and some of them want to swim with me in the water. I can teach them about life in the ocean and I can help them understand the beauty of life and nature.

B: Well, I'm a pigeon and I think that I am man's best friend. It's true that people like looking at dolphins, but I can help humans do more practical things. Everybody knows that pigeons are great for carrying letters and messages. I have taken many important letters all across the country - and I don't need electricity or petrol, I just fly wherever I need to go. And I'm a good friend because I spend time with people. Look around and you will see people feeding or talking to a pigeon on the street or outside a window. Humans love us, especially old people who need friends to talk to and care about.

C: That may be true, but I don't agree with you. Pigeons and dolphins may be friendly and funny, but how many people have pigeons or dolphins living in their homes? I'm a parrot. I think that I'm people's best friend, because I live with humans and I'm one of the family. The humans in my family talk to me and take care of me, and they have even taught me how to speak a few words in their language. A parrot is a much better friend than a dolphin or a pigeon, because a parrot is more like a human being. I mean, people use machines and computers to look for things in the ocean and send messages, but a machine can't be a real friend.

D: Dh deer, I must say that all of you have mentioned many good reasons. I think you are all good friends, but I believe that we need to think about what friendship really means. First, a true friend should be a friend because he or she wants to, not because they have to. Dolphins are kept in zoos. Pigeons are locked up in sheds. Parrots live in a cage, far away from their real home. Now, that's not true friendship. I'm a deer. I'm man's best friend, because I’m a real friend. I am free. I live in the forest and I'm a friend of the humans because I want to. Humans are good friends to me, too. They don't lock me up. They come to look at me in the forest and they sometimes help me with food if I need it. It's true that humans sometimes hunt us for food, but they only do so when they need food and they do not keep us locked up like pigs or cows. I'm man's best friend, because the humans treat me like a friend - not like a machine or a toy.

(The discussion continues.)

4. WRITING

Sample writing:

Last Saturday, something very unusual happened in our city. Mrs. Jones, a teacher, was doing her housework as usual. Her baby was sleeping in the backyard. Mrs. Jones said that it was just an ordinary Saturday. However, what happened next was not ordinary at all. "It was the most frightening thing that has ever happened to me," Mrs. Jones said.

Mrs. Jones usually keeps her TV on so that she can listen to it while she is doing the housework. "I like to sing when I'm cleaning or doing laundry," she said. As she was cleaning the living room, she heard someone on TV say that a young tiger had escaped from the zoo. Mrs. Jones said that she thought it was unusual to hear about a tiger running away from the zoo.

Mrs. Jones went to her backyard to look after her baby. When she got there, she saw something horrible. The tiger from the zoo was sitting next to her sleeping baby. Mrs. Jones wanted to scream, but she was afraid that the baby might wake up and frighten the tiger. "I thought that if 1 frightened the tiger it might attack my baby," Mrs. Jones said. Instead, Mrs. Jones quietly went to the kitchen and got some meat from the fridge. She threw the meat to the tiger. The tiger grabbed the meat and ran away.

Mrs. Jones rushed over to her baby. The baby was still asleep. She took the baby inside, closed the door, and called the police. She says that she will never forget what happened. "I think 1 am very lucky. The tiger didn't eat my baby and no one was hurt. "
