What do you think the colors in this photo mean? 2. Look at the information on this page. What do you think you will learn about in this unit? Thermal image of a house in New Haven, Connecticut, USA Think and Discuss  Questions 1. What do you think the colors in this photo mean? Example Answers I think the colors in this photo represent temperature. Red and yellow are probably warmer areas, and green and blue are cooler areas. It’s possible that the temperatures tell us where heat from inside the house is escaping. Since heat rises, it makes sense that most of the heat is escaping from the upper part of the house. Think and Discuss  Questions 2. Look at the information beside the photo. What do you think you will learn about in this unit? Example Answers I think we will learn about energy such as electricity, coal, and oil, and also how our use of energy is affecting the earth. 国际交流英语视听说 Unit 1 Energy and Our Planet Exploring the Theme Exploring the Theme  Energy and Our Planet Prudhoe Bay: a region on the northern coast of Alaska, U.S.A., north of the Arctic Circle.

In your notebook, list the families in order of their energy use (from the most to the least). Then write three ways in which each family can conserve energy. Analytical Listening Listening 1 Example Answers The Nelson family: • Dry the washed clothes outside whenever possible. • Drive a car that uses less fuel and use public transportation whenever possible. • Watch less television and turn the television off when not watching. The Panchal family: • Wash clothes by hand. • Use more solar energy. • If they must have a car, buy one that is fuel-efficient. To be continued >>> Analytical Listening Listening 1 Example Answers (Continued) The Chuma family: • They only use a small amount of electricity. • It will be hard for them to use less than they do now, but they could try to use sustainable sources instead of fossil fuels. Analytical Listening  Listening 1 Well, it’s just about seven o’clock, so why don’t we get started ... So, hello and good evening everyone and thank you for coming ... I’m Carl Jones, and tonight I’m going to talk to you about energy use around the world. Instead of talking in general terms, I decided to focus on three families from three different countries and discuss how each family uses energy in their daily lives. Can everyone hear me OK? OK, good. First, let’s look at the Chuma family, in a village in Botswana. Mr. Chuma is a tour guide and the family also raises cows. In this slide, you can see Mrs. Chuma doing some of her housework outside the family’s small house. She washes her clothes by hand, and then she hangs them in the sun to dry. She isn’t using any fossil fuels to wash and dry, which means she isn’t sending any greenhouse gases into the atmosphere. Analytical Listening  Listening 1 In the next slide, you can see three of the Chumas’ children and their neighbors’ children going to school. The children walk there, and in the rainy season they have to use this boat to cross the river. Again, you can see they aren’t using much energy, so they aren’t producing much carbon. Overall, the Chumas’ demand for fossil fuels is quite low. They use fossil fuels for a few important things, such as electric lights and a radio, so as a family, they have a fairly small impact on the environment. But global warming is having a significant impact on the people of Botswana, and the Chuma family is one example of this. Sometimes they don’t have water ... and there isn’t enough grass for their farm animals because of the dry climate. Now, let’s look at the next family—the Nelsons … Analytical Listening  Listening 1 The Nelsons live in Las Vegas, in the United States. Here, in this slide, you can see Brandi Nelson with her laundry. She’s listening to the news on a big TV while she folds laundry in their living room. She washed and dried these clothes in a machine, and there are many other things in their house that use electricity. In the next slide, you can see the Nelson children coming home from school. They attend a private school. The Nelsons drive them to school because there isn’t a bus. Brandi and her husband are entertainers, and they both drive to their jobs because it’s faster than public transportation. Their jobs are far from their home, so they use about a gallon of gasoline every day. The Nelsons want to conserve energy, and have done several things to help reduce the amount of energy they use. For example, this year they bought more efficient appliances. To be continued >>> Analytical Listening  Listening 1 They also want to put in a solar energy system in their house, but it’s very expensive. Their lifestyle puts a lot of carbon into the atmosphere, but they say it’s difficult to change their habits ... Finally, we have the Panchal family. This is Neetu Panchal, who lives in Jaipur, India. There are 11 people in her family, all living in one house. They have a washing machine, but she hangs her clothes on the top of her house to dry. The Panchals are saving money to build another room in their house for Neetu’s cousin and his wife. Neetu’s sister, Lalita, goes to work by bus. Here she is in this next slide here … Lalita works in a hotel far from their home. It takes her 40 minutes to get there. She hopes that the family will soon buy a car, so she can spend less time getting to work and more time at home with her family. To be continued >>> Analytical Listening  Listening 1 India has a very big middle class—more than 300 million people. Changes in the lifestyles of India’s middle class will have a big impact on the world’s greenhouse gases. For instance, by 2050, there will be about 600 million cars in India—more than any other country in the world ... and as the demand for cars increases, so will the demand for oil and gas.

Label the household appliances below. Which do you think uses the most electricity and produces the most carbon in a year? Work with a partner and rank them from 1 (the most) to 6 (the least). air conditioner clothes dryer computer hair dryer refrigerator TV Analytical Listening Listening 2 a. computer: 4 Computer monitors use a somewhat large amount of electricity. You can feel heat from computers and monitors, and that’s a sign of electrical consumption. b. air conditioner: 1 I think air conditioners use the most electricity and produce the most carbon because technological cooling and heating consume a lot of energy. Analytical Listening Listening 2 c. hair dryer: 6 I think a hair dryer uses the least electricity. It’s a small appliance, and people only use it for a few minutes each day. d. TV: 5 I think TV uses about the same amount of electricity as a computer, but maybe a bit less. It really depends on how many hours they’re on each day. Analytical Listening Listening 2 e. refrigerator: 2 I think an older refrigerator uses a lot of electricity and produces a lot of carbon. Even newer, efficient refrigerators use a lot of electricity, especially in hot weather. f. clothes dryer: 3 I think an electric clothes dryer is an inefficient appliance, and it requires a lot of electricity to dry the clothes.
