to make marriage vows (誓言) mean what they say.I am a good friend to my friends，and they to me.Without them，there would be nothing to say to you today.So here’s what I want to tell you today：Get a life.A real life，not a desire of the next promotion (提升)，the bigger paycheck，the larger house.Get a life in which you are not alone.Find people you love，and who love you.And remember that love is not

all the good in the world and try to give some of it back because I believed in it，completely and totally.And I tried to do that，in part，by telling others what I had learned.By telling them this：Read

that can be worn while they wash.The suit has been specially designed so that it can be cleaned under the showerhead.There is no need for soaking (浸泡)，dry cleaning—or even soap.The Japanese market has taken a liking to the “shower suit”，described as “revolutionary” by its owner Australian Wool Innovation (AWI)，which is the research and marketing body that represents Australian woolgrowers.Orders have been placed for 170,000 of the woolen suits.The suit could be worn in the shower，although it was probably better to hang it on a clothes hanger and carry it instead，AWI corporate affairs spokesman Stephen Feighan said.“The idea is that you hang it up and then...yougive it a spray (喷雾)，and it’s dry the next morning，” Mr Feighan said.A Japanese researcher working for AWI invented the suit by combining three technologies.The secret is the best lining (内衬)，which allows the suit to dry quickly.The shower suit attracted busy corporate people，particularly those who often traveled or stayed up late，Mr Feighan said.The airline industry was also interested.Mr Feighan confessed he had not worn one of the suits yet，or tried to wash it in the shower，because they cut to fit Japanese figures.AWI believes that the shower suit will spread from the Japanese market through Europe and India.Mr Feighan hoped the suit，made from local wool，would be available in Australia in 12 to 18 months’ time.5．What is the writing purpose of the article?A．To introduce a newly-designed shower suit.B．To help the white collars arrange their life more sensibly.C．To provide suggestions on saving

of the quality of fast dry for its best cloth.C．It is not suitable for hanging.D．It has attracted more orders than any other suit.7．The suit draws the attention from all the following groups

Feighan?A．The invention of the suit.B．The try-on of the suit.C．The combination of the three technologies on the suit.D．The popularization of the suit and best wishes for it9．It can be inferred from the passage that________.A．Australians prefer foreign markets to the domestic oneB．wool is the most favorite material for clothingC．westerners have different body sizes and figures from

Teaching important pointsHelp the students learn how to debate over the topic “We should do nothing about global warming.”Teaching difficult pointsEnable the students to learn the writing skills of the text and get a better understanding of articles of this kind.Teaching methodsReading, speaking and group work.Teaching aidsMultimediaTeaching procedures & waysStep1 GreetingsGood afternoon，everyone. I’m very happy to be here together with you. I hope you will enjoy this class.Step 2 Leading inAs we all know, we depend on energy to do many things in our daily lives. What things use energy around us? (light, computer, fridge, hairdryer, television, washing machine, electric-bike, bus, car, motor-bike and so on.)Since energy is so important for us, can you tell me some sources of energy? Are they renewable or non-renewable? (show some pictures to help). From the above, we know some sources are renewable, but some are non-renewable, so we must save energy. Before reading, let’s learn something related to global warming.Step 3 Pre-readingShow a picture of greenhouse on the screen and ask the students some questions.1. What is it in the picture? (A greenhouse).2. What is it used for? (A greenhouse is made of glass and is used for growing plants, especially during cold weather).3. How does it work? (The air inside is warm because the glass traps the heat from the sun and keeps it from escaping. This makes the greenhouse heat up and so the plants can grow throughout the cold period).Today we aren’t going to talk about greenhouse, but we are going to talk about greenhouse gases.4. What are greenhouse gases? (In the atmosphere surrounding the earth there are gases, which are called “greenhouse gases”, including carbon dioxide, methane and water vapor).5. What do you think greenhouse gases do? (They trap heat from the sun and therefore warm the earth).Explain: Yes. This is called the greenhouse effect. Because of the greenhouse effect, our earth is becoming warmer and warmer. Does it matter? What’re your opinions? This is the topic today we are going to learn: “THE EARTH IS BECOMING WARMER —BUT DOES IT MATTER?”It is an article from a magazine. At first, please read it quickly, and then answer the following questions.Step 4 Fast-readingGet the students to read the passage fast and meanwhile help the students form a good habit of reading.Skim the article and answer the following questions:1. Who wrote the article? (Sophie Armstrong)2. What is the name of the magazine? (Earth Care)3. What are the names of the three scientists mentioned in the article? (Dr. Janice Foster, Charles Keeling, George Hambley)4. What do the 3 scientists think about global warming?(Dr. Janice Foster thinks the effects of global warming could be very serious.George Hambley thinks global warming will be mild with few bad environmental consequences. Charles Keeling believes it is the burning of more and more fossil fuels that has resulted in a big increase in carbon dioxide.)5. What is the main topic of the article? (Global warming/ the warming of the earth.) Before reading the article, you can look through the questions first. Read as quickly as possible. You don’t have to read every word. Here’s tip for you:Step 5 Detailed readingNow let’s read the text again for some details.Read the article again carefully and find out the following statements are true or false1). It is believed that global warming is caused by the activities of humans. ( )2).Janice Foster believes that she can measure the future global rise in temperature.( )3). The rise in carbon dioxide is causing a steady increase in global warming.（）4). George Hambley believes that global warming will do good rather than harm tothe earth. ( )5). It is clear what the effects of global warming will be. ( )(T, F, T, T, F )Step 6. Structure main ideas and writing skills of the passageNow let’s learn the text on the whole. Analyze the structure, main ideas and writing skills.1. What is the writing style? ( A )A. Expositive (说明文)B. Practical (应用文）C. Argumentative (议论文）D. Narrative（记叙文）As usual an expositive essay includes four parts-title, introduction, body, and conclusion. The first paragraph is introduction, the last paragraph is conclusion, and the middle part is body. Now, please divide our text into several parts. How many parts can the text be divided into?( 4 parts : Part 1-para 1; part 2- para2,3,4; part3-para 5; part4-para6 ). We have known the structure of the text, and next, let’s look at the main idea of each part. Look through the text and then finish the task on the screen.2. Match the parts with the main ideas:Part1 Explain how global warming comes aboutPart2 Introduce the topic of global warming.Part3 It’s up to readers to think and decide whether people should do something about global warming or not.Part4 List two different attitudes among scientists towards global warming. In this article, there are many writing skills. Please find them out, and then finish the task on the screen.3. Match the parts with the writing skills:Part1 Using a question, leaving readers to think over the issuePart2 Giving examples, using graphs, explanationPart3 Giving examples, making contrast (comparison)Part4 Raising a questionThese writing skills are very useful, if you don’t know how to write an expositive article, you can use the skills.Step 7 DiscussionFrom the text we know that there are some very different attitudes among scientists towards the effects of global warming. Some think the effects will be terrible, while some others believe that we should not worry about it. What’s your opinion? Now let’s have a discussion about the statement: “We should do nothing about globalwarming”. Do you think so? What’s your opinion? You can have a discussion in groups of six. Before discussing, you must follow these instructions.Put the following instructions on the screen.1. Get into groups of six. Decide which three in your group are going to agree with the statement (Group A) and which three are going to disagree with the statement (Group B).2. Group A discuss why they agree with the statement; Group B discuss why they disagree.3. Group A and B get together. Tell each other the reasons why they agree or disagree with the statement.Check the results of discussions.From the discussions, we know there are many different opinions about the effects of global warming, but one thing is for sure. It’s that in our daily lives we can do many things to save energy and protect the environment. Each of us makes a difference, so we must try our best to save energy and protect the environment. Now let’s say the slogan on the screen together, again, and again.Step 8 HomeworkAt last it’s your homework time.According to the results of our discussions, please write an article about the effects of global warming.Time is limited, so much for today, thank you for your listening, thank you for your co-operation, thank you. Class’s over, goodbye.。
