Task3: Curbing carbon emissions Script
Although it is not an easy task, Chins is striving to fulfill the promise to cut its carbon dioxide emissions per unit of GDP by 40 to 45 percent in the next 10 years. Zhang Guobao, Director of the National Energy Administration, said, \ government puts great emphasis on seeking harmonious development between cities and the environment, and is readjusting the energy structure by giving priority to the development of clean and low-carbon energies, including hydroelectric, nuclear, wind and solar power.\ small, coal-fired plants with a total capacity of 60.06 million kilowatts in the past four years. This year's target of closing 10 million kilowatts of capacity will be achieved by August.
\ercent of our power will be generated from non-fossil sources by 2020,\
accounts for only 7.8 percent. China is making efforts to increase the proportion of clean energy in its total energy consumption. Statistitics show that China invested US$34.6 billion in clean energy last year, exceeding the United States which invested US $18.6 billion. Thus, China has become the world leader in generating clean energy. Five years earlier, China's investment in clean energy was only US$ 2.5 billion. However, China's carbon emission reduction target cann't be achieved easily. The shift to a low-carcon economy might be met at a cost to society. For instance, more than 400,000 people were laid off as a result of the shutdown of small coal-fired power plants in the past four years. Many studies indicate that the effort to curb greenhouse gas emissions may delay China's development, affect people's income, and lead to unemployment. Questions and key 1. What is the pasage mainly about? 2. From four years ago unti August this year, how many kilowatts of coal-fired plant capacity will have been closed? 3. By 2020, what will be the prpportion of non-fossil energy in the total power in China? 4. Which of the following is true of the investment by China and the United States in clean energy last year? 5. Which of the following is not mentioned in the p
assage as a problem arising from curbing greenhouse gas emissions? Kes: 1D 2.D3 . A 4.B 5.C
IV. Speaking Out
MODEL 1 Our globe is in danger
John: How is your Grandma getting along during this usually hot weather? Nora: Over the last few years, Granny has been complaining that the hot, humid weather is killing her. She believes the weather has changed. John: What she means is the climate‘s long-term conditions; weather refers only to day-to-day conditions. Nora: , she says summer is hotter, and winter wetter. But I tried to comfort her, saying, ―It‘s all in your mind, Granny.‖ John: She‘s right, you know. The greenhouse effect does bring global warming and rain. Nora: How can I explain global warming and greenhouse gases to a 97-year-old Granny? John: Tell her the earth now is like a real greenhouse made of glass panels that let in light and trap heat. Nora: Think she‘ll want to know that carbon monoxide from earth makes greenhouse
gases? John: Everybody should know what cause global warming; otherwise we won‘t stop it. Nora: I‘ll tell Granny not to burn any more wood or coal, or to use spray on the hair. J
ohn: OK, joke about it, but it won‘t be so funny when the polar icecaps melt and oceans rise.

A: How are you getting along during this usually hot weather? B: Not well at all. Over the last few weeks the hot, humid weather is killing me. I believe the climate has changed. A: , the summer is hotter, and winter wetter. B: Do you know why all this has happened? A: The greenhouse effects bring global warming and rain. B: What do you mean by greenhouse effects? A: The earth is now like a real greenhouse made of glass panels that let light in and trap heat. You know, carbon monoxide from earth is a greenhouse gas. B: I see. Everybody should know what cause global warming; otherwise we won‘t stop it. A: The important thing is that human beings should take steps to reduce global warming. B: What can we do then? Perhaps we should not burn any more wood or coal. A: Right. Also we should try to produce less CFCs or Freon. B: How can we achieve that? A: Don‘t use aerosol spray on your hair, and depend less on air-conditioners and refrigerators.. B: But it‘s hard to give up all this. A: But we must take action before polar icecaps melt and oceans rise.
MODEL2 Rainforests will soon be only a memory. Script
Susan: Hey, Chris, there is an environmental group on campus asking for donations
to save the rainforests. Chris: So what? Susan: So what?! Don‘t you want to save the rainforests? Chris: But there‘re no rainforests in our country. They need hot, tropical climates. Susan: Come on. A rain forest is any forest where heavy rainfall leads to dense vegetation. Tropical rainforests can be found in hoe, tropical areas, but there are also cool rainforests, including one in southeast Alaska. Chris: How did you know that? Susan: Well, I‘ve just read a book on rainforests. You know, 140nillion people live in the world‘s rainforests, and 35 percent of the world‘s plant and animal species exist only in rainforests. Chris: Wow, I‘m impressed. So what else have you learned? Susan: Most of the world‘s rainforests are in danger of destruction by loggers, farmers and developers. They are disappearing at a rate of 1000 acres a minute! Chris: It‘s terrible! Susan: , we‘ve got to find a way to save them. Now would you like to give a donation? Chris: Sure.
