Unit 5 The Villain in the Atmosphere I. Teaching Aims 1. Enlarge the students’ vocabulary by learning the new words and doing the vocabulary exercises. 2. Help the students to get the general idea of the article. 3. Help the students to know the importance of environmental protection. 4. Help the students to build up their language skills through more exercises on oral practice, phrases and expression, grammar, writing, etc. II. Key and Difficult Points 1. New Words and Phrases poisonous, do harm, essential, convert, serve as, apparently, advance, transparent, visible, creep, replace, consume, cut down 2. Sentences (1) It is not very poisonous and it is present in the atmosphere in so small a quantity — only 0.034 percent — that it does us no harm. (2) But here is what this apparently harmless and certainly essential gas is doing to us: (3) Florida will disappear beneath the waves, as will much of the British Isles, the crowded Nile valley, and the low-lying areas of China, India, and Russia. (4) However, the atmosphere is not quite as transparent to infrared radiation as it is to visible light. (5) Less heat is lost at night, for that reason, than would be lost if carbon dioxide were not present in the atmosphere. (6) Thus, not only is more carbon dioxide being added to the atmosphere through burning of fuel, but as the forests disappear, less carbon dioxide is being removed from the atmosphere by plants. III. Teaching Methods Discussion, explanation, ask and answer IV. Time: 4 periods V. Teaching Procedures:
Step one Introduction 1.Warm-up questions: Give the students the following topics to discuss and then ask them to answer these questions (1)What's the weather like in your hometown?Do you like it?Why or why not? (2)Have you ever noticed any changes in your hometown or in the city you're now living in?What are they? (3)Do you have any idea of the greenhouse effect?How does it affect the temperature on Earth? 2.Introductory Remark When we read newspaper or watch news on TV,frequently we come across terms such as "greenhouse effect","global warming crisis",etc.What is the "greenhouse effect"?What does it mean by the"global warming"?How is it that it has become a crisis?It is good if you know and even can explain these terms in English,and if not,well,never mind,for Isaac Asimov provides an explanation both interesting and easy to understand in The Villain in the Atmosphere 3.Background Information (1)About the author Isaac Asimov(1920-1992)was a Russian-bom American author and biochemist a highly successful and exceptionally prolific writer best known for his works of science fiction and for his popular science books.He wrote or edited over 500 volumes and is by general consensus a master of the science-fiction genre. (2)About the article The Villain in the Atmosphere,originally titled Are We Drowning Our Tomorrows?,was first published in 1986.This article is intended as an explanation of the process called the "greenhouse effect"and the possible impacts of"global warming"on our planet,though all these particular terms do not appear in his writing.

Step one Introduction 1. Warm-up questions: Give the students the following topics to discuss and then ask them to answer these questions. (1) What’s the weather like in your hometown? Do you like it? Why or why not? (2) Have you ever noticed any changes in your hometown or in the city you’re now living in? What are they? (3) Do you have any idea of the greenhouse effect? How does it affect the temperature on Earth? 2. Introductory Remarks When we read newspaper or watch news on TV, frequently we come across terms such as “greenhouse effect”, “global warming crisis”, etc. What is the “greenhouse effect”? What does it mean by the “global warming”? How is it that it has become a crisis? It is good if you know and even can explain these terms in English, and if not, well, never mind, for Isaac Asimov provides an explanation both interesting and easy to understand in The Villain in the Atmosphere. 3. Background Information (1) About the author Isaac Asimov (1920-1992) was a Russian-born American author and biochemist, a highly successful and exceptionally prolific writer best known for his works of science fiction and for his popular science books. He wrote or edited over 500 volumes and is by general consensus a master of the science-fiction genre. (2) About the article The Villain in the Atmosphere, originally titled Are We Drowning Our Tomorrows? , was first published in 1986. This article is intended as an explanation of the process called the “greenhouse effect” and the possible impacts of “global warming” on our planet, though all these particular terms do not appear in his writing. (3) Global Warming
Global warming refers to an average increase in the Earth's temperature,which in turn causes changes in climate.A warmer Earth may lead to changes in rainfall patters,a rise in sea level,and a wide range of impacts on plants,wildlife,and humans.When scientists talk about the issue of climate change,their concem is about global warming caused by human activities. Step Two Global reading Give the students 10 minutes to read the text as quickly as they can,and ask them to think about these questions in the process of reading. 1.True or False Questions: (1)Carbon dioxide is very poisonous,although it is present in the atmosphere in a small quantity,it does us harm. (2)Carbon dioxide is one of the essential gases to life in theatmosphere. (3)The sea level is rising very slowly from year to year,mainly because of too much rain in these areas. (4)Among the gases in the atmosphere,only the concentration of carbon dioxide may result in preventing heat around the Earth from escaping (5)The concentration of carbon dioxide increased steadily and it will be twice what is now by 2020. (6)Burning coal,oil and natural gas are ways to reduce carbon dioxide in the atmosphere (7)People are the real villains actually. (8)In order to save ourselves,we must have new sources of fuel that do not involve the production of carbon dioxide. 2.Structure PartI (Para.1-3) It introduces an essential gas to life-carbon dioxide and its influence Part 2(para.4-13) It analyzes what carbon dioxide does to the temperature of the Earth and the results
Global warming refers to an average increase in the Earth’s temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities. Step Two Global reading Give the students 10 minutes to read the text as quickly as they can, and ask them to think about these questions in the process of reading. 1. True or False Questions: (1) Carbon dioxide is very poisonous, although it is present in the atmosphere in a small quantity, it does us harm. (2) Carbon dioxide is one of the essential gases to life in the atmosphere. (3) The sea level is rising very slowly from year to year, mainly because of too much rain in these areas.

(7) People are the real villains actually. (8) In order to save ourselves, we must have new sources of fuel that do not involve the production of carbon dioxide. 2.

At the same time, due to the increase of population, more and more forests, which could absorb carbon dioxide, are turned into farming land, thus aggravating the greenhouse effect and causing the whole Earth to grow warmer and warmer. To stop this warming trend, every country must first try to find alternative energy sources, such as solar and atomic power, and reduce the consumption of fossil fuels. Then effective measures must be taken to protect whatever trees are left uncut in the world. Furthermore, new trees should be planted every year so that forests will cover more and more areas of our globe. As individuals, we can also contribute to the effort to stop global warming. In our homes, we can use energy efficient appliances, or use solar or wind power, which don’t emit carbon dioxide. While going out, we can use public transportation instead of driving a private car. We can even walk or bike to school or work. If we must drive, we can use a car that gets high mileage, or join a car pool when possible. With the joint effort of every country and every individual, we may hope to restore the concentration of carbon dioxide in the atmosphere to its previous levels and prevent the disasters that threaten as a result of global weather change
