Unit 22 Environmental ProtectionEnvironmental problemsEnvironmental problems are becoming more and more se rious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man's existence.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. The polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation has been greatly reduced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to co n trol air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.In my opinion, to protect environment, the gove rnment must take even more concrete measures. Firstly, it should let people fully realize the importance of environmental protection through education. Secondly, much more efforts shou ld be made to put the population planning policy into practice, because more peopl e means more pollution. Finally, those who destroy the environmentintentionally should be severely punished. We should let them know that destroying environ ment means destroying mankind themselves.As we all know, there is only one earth. The environment must be linked with social ethics, character education and practice acts Everyone must fulfil his responsibilities and obligations to protect the environment.环境问题全世界的环境问题正变得越来越严重。

Ability goals 能力目标Learn what global warming is and enable students to learn its causes and consequences.3. Learning ability goals学能目标By reading an article help students to learn how they can help solve the problem of global warming.Teaching important points教学重点What human activities are causing global warming and how we can help solve the problem of global warming.Teaching difficult points教学难点How we can help solve the problem of global warming.Teaching methods教学方法Listening, reading, discussing.Teaching aid 教具准备Multimedia computer.Teaching procedures & ways 过程与方式Step I Leading inIn this procedure students will talk about the causes and consequences of global warming. Begin the lesson by asking students to discuss the questions in before you startT: Yesterday we learned from the passage in Culture Corner that gases from burning coal and oil are the major causes of global warming. Did you make your survey on how students come to school?S1: I asked 40 students. Ten in the forty come to school by bus. Twenty-one ride bicycles. Eight of the forty take a car and only one walks to school....T: From the survey you made we can see most of students in our school take a green way to school. I’m glad we are not having so many cars. Because gases pumped into the atmosphere from cars will speed up global warming. Have you noticed that in 2006 we had a very warm winter? Experts say global warming has changed the climate in China. In this class we are going to learn more about global warming. We will read an article “Can we take the heat?”Before we start the text, please discuss the question in Before you start.Step II Before you startDiscuss the two questions in Before you start and work out the meanings of the given words. T: OK, open your books and discuss the question in Before you start on Page 6. Which countries do you think contribute more to global warming, developed countries or developing countries?Ss: Developed countries. Because they have more cars and factories and gases from cars and factories are the major cause of global warming.T: Good answer. Please scan the text for the given words in Ex2 and try to work out their meaning.While students are discussing the words, Teacher should walk around the classroom and give necessary help when needed.Several minutes later, ask students to present their answers either in English or Chinese. Students may even be encouraged to explain the meanings using pictures. Show the suggested answers on the PowerPoint.Step III Read to learnDeal with the reading part.ScanningAsk students to scan the text and find what exactly global warming is.T: What is the title of Lesson 1?Ss: Global Warming.T: Do you know what exactly global warming is? Please scan the text and find the answer in the text.Ss: Global warming refers to an average increase in the Earth’s temperature.T: Quite good! Then skim the text and find what human activities are causing global warming. S: As a result of increased industry, agriculture, the cutting down of forests, the increase in transport and the burning of fuels, nearly 6 tones of carbon dioxide goes into the atmosphere every year for every one of the Earth’s 6 billion people. Over the last 100 years, the global average temperature has increased by 1°F. If we continue to produce carbon dioxide and other gases in such quantities, we are condemning life on Earth and should expect severe consequences.SkimmingShow the following form on the PowerPoint and ask them to work in groups and complete the form.Ask students to skim the text and then finish Ex3 on Page 7. Students may discuss the questions in groups.T: Look through the questions in Ex 3 on Page 7 first. Then skim the text to find the answers. Then check the answers with the whole class.Suggested answers:1. Global warming is an average increase in the Earth’s temperature.2. Increased industry, agriculture, the cutting down of forests, the increase in transport and the burning of fuels are causing global warming.3. By 1°F.4. Yes, they are. Because greenhouse gases trap heat from the sun in the Earth’s atmosphere. Otherwise the earth would be very cold and unsuitable for life.5. We can take public transport, recycling, using low-flow shower heads, buying efficient light bulbs to stop global warming.Step IV ExplanationDuring this procedure teacher will play the tape for students. Students will underline the difficult sentences. After listening to the tape, Teacher will explain the text and deal with language problems.T: After doing the comprehension of the text, let’s deal with some difficult language focuses. Now I will play the tape for you .Please make a mark where you have difficulties.After listening to the tape, explain the difficult sentences to students. Before explaining the difficult points, students are asked to refer to the notes to the text on page 114.T: Do you have any difficulties with the text？S1: Could you please explain the second paragraph to us?T: The second paragraph tells us the association greenhouse gases have with global warming. The “greenhouse effect”often gets a bad rap because of its association with global warming, but the truth is we couldn’t live without it. Life on earth depends on energy from the sun. About 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space. The rest reaches the planet’s surface and is reflected upward again as a type of slow-moving energy called infrared radiation.As infrared radiation is carried aloft by air currents, it is absorbed by “greenhouse gases”such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere.Although greenhouse gases make up only about 1 percent of the Earth’s atmosphere, they regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet. This phenomenon is what scientists call the "greenhouse effect." Without it, scientists estimate that the average temperature on Earth would be colder by approximately 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain our current ecosystem.While the greenhouse effect is an essential environmental prerequisite for life on Earth, there really can be too much of a good thing.The problems begin when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature.Today, the increase in the Earth’s temperature is increasing with unprecedented speed. To understand just how quickly global warming is accelerating, consider this:During the entire 20th century, the average global temperature increased by about 0.6 degrees Celsius (slightly more than 1 degree Fahrenheit).Using computer climate models, scientists estimate that by the year 2100 the average global temperature will increase by 1.4 degrees to 5.8 degrees Celsius (approximately 2.5 degrees to 10.5 degrees Fahrenheit).Now please read the first sentence in the second paragraph. What’s the function of that-clause? S1: It is an attributive clause modifying ‘an average increase’.T: Good! ‘that’refers to ‘an average increase in the Earth’s temperature’. From this sentence we can learn an average increase in the Earth’s temperature will cause climate changes. In the second sentence there is also an attributive clause caused by ‘which’. What does ‘which’refer to?S2: ‘Which’refers to greenhouse gases.T: Right! Greenhouse gases trap heat from the sun in the Earth’s atmosphere. Without greenhouse gases, the earth would be very cold and impossible for life. Do you have any other questions?S2: No.T: There are many useful phrases in the te xt. Please sum up the phrases and then we will analyze the text.Step V PracticeDeal with Ex 5 on page 7. Ask students to do the exercises individually. While doing the exercises, remind students that they should pay attention to the correct form of the given words. Make necessary changes where needed. Then check the answers with the whole class.Step VI Analyzing the textHelp students analyze the structure of the text. Ask students to discuss in groups and later each group will speak out their opinions. After this, show the suggested answers on the PowerPoint. T: OK. Let’s read the text again. Please look at the structure of the text. You are given 5 minutes.…T: Please stop here. I’m glad you thought actively and had a heated discussion. What is its writing style?Ss: This text is an expository writing.T: What is the topic of the text? What is the text about?S1: Global warming.S2: The text introduces what global warming is.S3: Its causes and consequences.S4: And how we can help solve the problem of global warming.T: Quite good. How many parts consist of the a rticle? What’s the main idea of each part?S4: In my opinion the article is made up of four parts. In the first paragraph the author raises the question. In the second paragraph we can find its definition. And the third and fourth paragraphs tell us its causes and consequences. And the last part the author gives us some tips on how to solve the problem.T: Well done!If students have different opinions, Teacher may help them analyze the text.Show the following on the PowerPoint.Part1 (the first paragraph) Global warming could be one of the biggestenvironmental problems facing the 21st century.Part2 (Para.2) W hat global warming is.Part3 (Para.3-4) Its causes and consequences.Part4 (Para.5) Tips on how to solve the problem.T: After learning the tips on how to solve the problem, let’s discuss what we will do every day to help reduce greenhouse gases. Please make your voice heard and get involved in the discussion. After the discussion, please write your suggestions on a piece of paper and put it on your bulletin board so that you can share your ideas with the whole class.Step VII DiscussionDivide the students into different groups and discuss the questions of Ex 4 on Page 7. They are given several minutes to discuss. Each member is encouraged to think actively and participate in the discussion. Make sure all the students have their own opinions. Every group should have their secretary to write down the discussion. Then each group should pin the suggestions on the bulletin board so that everyone can read them and learn about others’good way to reduce green house gases.T: Please work in groups and express yourself freely. Because everyone has his or her own practical way, please share your ideas with your group members.…T: Before starting your discussion, please read the following.Show the following on the PowerPoint.The Top Five Global Warming Polluters!1.The United States2.China3.Russia4.Japan5.America’s Cars and Light TrucksChina to Invest $175 Billion in Environmental Protection Over Five Years China has created an “economic miracle”over the past two decades, air pollution is choking its cities, chemical spills are fouling its rivers and drinking water supplies, soil contamination is undermining its agriculture, and raw sewage is causing widespread disease. This environmental toll has led to internal riots, international protests, and the arrest and trial of a leading Chinese environmentalist.In 2006, China pledged to invest $175 billion by 2010 to control water pollution, improve air quality, increase solid waste disposal and reduce soil erosion —investments intended to pay economic as well as environmental dividends.A sample of Ex 4 on page 7Responsible ChoicesThe choices we make and the products we buy test our commitment to maintain a healthy planet. When we burn fossil fuels such as oil, coal, and natural gas to run our cars and light our homes, we pump carbon dioxide (CO) into the air. This thickens the heat-trapping blanket that2surrounds the planet, causing global warming.Choosing modern technology can reduce our use of fossil fuels and help protect the planet. These steps will help curb global warming, save you money, and create a safer environment for the future.Drive Smart!A well-tuned car with properly inflated tires burns less gasoline cutting pollution and saving you money at the pump. If you have two cars, drive the one with better gas mileage whenever possible. Better yet, skip the drive and take public transit, walk, or bicycle when you can.Replace incandescent light bulbs with compact fluorescents bulbs.Especially those burn the longest each day. Compact fluorescents produce the same amount of light as normal bulbs, but use about a quarter of the electricity and last ten times as long. Each switch you make helps clean the air today, curb global warming, and save you money on your electricity bill.Become a smart water consumer.Protecting forests is a big step on the road to curbing global warming. Trees "breathe in" carbon dioxide, but slash-and-burn farming practices, intensive livestock production, and logging have destroyed 90 percent of the native forests in the United States. And you can take action in your own back yard —planting shade trees around your house will absorb COand2, slash your summer air-conditioning bills.Reduce! Reuse! Recycle!Producing new paper, glass, and metal products from recycled materials saves 70 to 90that would result if the product came from percent of the energy and pollution, including CO2virgin materials. Recycling a stack of newspapers only 4 feet high will save a good-sized tree. Please...buy recycled products!Mount a local campaign against global warming.Educate your community about how it can cut global warming pollution. Support measures at the national, state, and local level that:Make automobiles go further on a gallon of gas;Accelerate the use of clean, renewable energy sources, such as solar and wind;Increase energy efficiency and conservation;Preserve forests around the world.Step VIII HomeworkPick out the reporting verbs in the text.11。
