1. 课标人教实验版 高二 Module 6 Unit 4

2. Listening ＆ Speaking

3. Listening and Speaking I. Listen to the tape and answer and decide which statements Professor Keeling does NOT agree with. 1. We should stop depending on fossil fuels for our energy. 2. 90% of our energy comes from fossil fuels.

4. 3. We can replace fossil fuels with cleaner sources of energy. 4. Nuclear power is a good source of energy.

5. 2. Listen to Part 1 again and tick the energy sources that are mentioned. Complete the notes on them. Sources of energy Notes Fossil fuels Produce carbon dioxide cheap and concentrated form of energy

6. Wind power Energy from the sun Nuclear power clean not very practical with present technology does not produce carbon dioxide dangerous clean not practical: need huge areas of land to provide enough energy

7. 3. Listen to Part 2 and the list three things we can do to save energy. First we must try to find ways to use fossil fuels that does not put carbon dioxide into the air. Second we must produce products that are economical with energy. Third we must ask people to cut down on the energy the use.

8. 4. Listen to part 2 again and fill in the blanks. LI BIN: …What about _______? They don’t cut down on their use of ______. energy factories

9. KEELING: No, they don’t. However, that is a _______ we must work on as a ______ community. That means ________ and _________ countries will have to work together. problem global developeddeveloping

10. LI BIN: But it’s not the _________ countries that put most of the carbon_______ into the air. The developed countries are really the ones to ______. developing dioxide blame

11. Note: The USA is the largest energy user in the world and the largest producer of the greenhouse gas carbon dioxide. China comes second in both of these. Listening text

12. China has been going through huge economic development, and has had as much growth in one decade as the industrial world experienced in nearly a century. However, it has been at a high cost to the environment.

13. FOSSIL FUELS AND OTHER FORMS OF ENERGY Li Bin, a university student, is interviewing Professor Keeling on the local student radio station about the use of fossil fuels and other sources of energy.

14. Part 1 L: Professor Keeling, I've read that we must stop using fossil fuels if we want to reduce the amount of carbon dioxide in the air. K: Yes, that's right, Li Bin. However it’s difficult.

15. Our modern industrial societies depend on the energy we get from fossil fuels. It's a very cheap and concentrated form of energy.

16. L: Is it true that about 90% of the world's energy comes from fossil fuels? K: Yes, that's correct. And there is enough to last for centuries.

17. L: Could we replace fossil fuels with clear sources of energy like sun or wind power? K: I'm afraid not. We just can’t produce enough. You need huge areas of land to produce enough wind energy. The technology we have at present cannot provide enough sun energy.

18. L: So what about nuclear power? That doesn’t produce carbon dioxide. K: True, but it’s very dangerous. Remember the accident at Chernobyl. People are still dying of the radiation that was produced by THAT disaster!

19. Part 2 L: So what can we do? K: Well, there are three things. First we must find ways of using fossil fuels that won’t put carbon dioxide into the air. Second, we must produce products that are economical with energy. Third, we must ask people to cut down on the energy they use.

20. L: But that’s on a personal level. What about factories? They don’t cut down cut down their use of energy. K: No, they don’t. However, that is a problem we must work on as a global community. That means developed and developing countries will have to work together.

21. L: But it’s not the developing countries that put most of the carbon dioxide into the air. The developed countries are really the ones to blame. K: That’s true. So we must work together because global warming will affect everyone. If we want the future generations to have a good life, we must ALL look after the planet.

22. Answer key for Exercise 2(P62): Questions to Julie Her answers What is Millennium Kids Who started it? When? An organization by kids of kids; concerned with the environment Four students in Australia; in 1996

23. Why was it organized What play did they perform last year? To draw attention to the environment The horse that Saved the World

24. What was the purpose of performing the play? To explain why it’s better for the environment if we walk to school, ride bikes or go by bus

25. Answer key for Exercise 3: Methods of saving energy: Buy energy-saving goods Turn off appliances when not using them Projects that Millennium Kids have done: 1 planted trees 2 developed activities that reduce, reuse and recycle waste 3 planned ways to reduce recycle and reuse plastic bags

26. MILLENNIUM KIDS Julie, a teenager who belongs to an organization in Australia called Millennium Kids is visiting a class. The teacher and students are asking her questions about the organization. Listening text

27. Part 1 T: Hello Julie. It’s so nice to see you here. Can you tell us about Millennium Kids? J: Sure. It's an organization run by kids for kids. It’s concerned with the environment.

28. S1: Julie, may I ask how it started? J: It was started by four Western Australian kids who organized a children's conference on the environment in 1996. Now we hold a conference every year.

29. Kids come to it from all over Australia -- and from other countries too. It's great fun. We discuss what we’ve done and decide what projects we’ll do in the following year. S2: That sounds so interesting! What sorts of projects do you do?

30. JULIE: Well, all sorts. Last year we had a school project to help kids understand about global warming. Actually, we performed a play called "The Horse that Saved the World". It taught kids not to travel to school so often by car. It explained why it’s so much better for the environment if we walk, ride a bike or go by bus. (murmurs of agreement).

31. Part 2 S2: Hey, I ride to school already! Is there anything else I can do? J: Oh, lots of things. You can encourage your parents to buy electrical goods that can save energy; you can wear a warm sweater instead of turning on the heating in cold weather; and you can

32. turn off electrical appliances when you are not using them. S: Thanks for that. What other projects have you done? J: We’ve planted trees and develop activities that reduce, reuse and recycle waste. This year we’re asking kids to think of ways to reduce, reuse and recycle plastic bags– they are such a problem.

33. S3: That sounds very interesting. T: Well, thank you, Julie. Millennium Kids certainly sounds like a good organization. J: Yes, it’s fun being a Millennium Kids. It’s also important. If we don’t care for the environment, we may not have a future. That’s a pretty good reason to do something, don’t you think?

41. CLEAN UP AUSTRALIA DAY Tom is giving a talk to his class about Clean Up Australia Day. Part 1 Today I'm going to tell you about Clean Up Australia Day. Listening text

42. It’s one day of the year when people in Australia get together to clean up their local environment. It started in 1987, when Ian Kierman was competing in a round-the-world yacht race.

43. When he was shocked during the race by the pollution he found on the oceans. There was rubbish floating everywhere. So when he got back to Sydney he decided to organize a clean- up day. He began with Sydney Harbour.

44. In 1989 he got 40,000 volunteers to help him clean it up. They collected tonnes of old car bodies, plastics of all kinds, glass bottles and cigarette butts. It was so successful that Ian organized the first Clean Up Australia Day in 1990. This time more than 300,000 people offered to help and it was another success.

45. Since then it has become a yearly event with more and more people coming to help. Here’s a table showing the most common kinds of rubbish found in 2001 on Clean Up Australia Day. You can see that the top three are cigarette butts, glass bottles and plastic bags.

46. We found that some of them could be recycled. In fact Clean Up Australia Day works so well that we now have Business Clean Up Day and School Clean Up Day as well.

47. Part 2 After he started Clean Up Australia Day, Ian moved on to Clean Up the World Day. He got the support of the United Nations Environmental Programme, and as a result, Clean Up the World Day began in 1993. in the first year 30 million people in 80 countries were involved.

48. By 2001, the idea had become so popular that 40 million people from 128 countries took part. They cleaned streets, beaches, river banks and parks. I think Ian Kierman is a wonderful man. He is an inspiration to all those who have a commitment to solve world problems.

49. He makes them realize that people can take control of a problem themselves. They don’t have to wait for their government to act. They can also feel better knowing that they have contributed to improving the environment all round the world. (sound of students clapping)
