英语：Unit 4 《Global Warming 》教案-reading （新人教版选修6）Period 2 Pre-reading, Reading, ComprehendingTeaching Goals:1.To read about global warming.2.To get some idea about the effect of global warming.3.To develop some basic reading skills.Teaching Procedures:Step 1. Warming UpPurpose: To arouse Ss interest in learning about global warming.1. Team workAnswer the questions below:(1) Have you ever seen a greenhouse?(2) How does a greenhouse work?(3) What do you think greenhouse gases do?2. Group workLook at the picture, and ask Ss some questions.T: What is this building made of?S1: It’s made of plastic.T: What’s its purpose?S2: Plants can grow in it when it’s cold outside.T: How does it work?S3: The glass traps the heat from the sun, making the air warm so that plants grow better.Step 2. Pre-readingPurpose: To get Ss to learn about greenhouse gases.1. Group workNow look at the word “GREENHOUSE GASES”. What does it mean?Greenhouse gases (GHG) are gaseous components of the atmosphere thatcontribute to the greenhouse effect .The major natural greenhouse gases are watervapor, which causes about 36-70% of the greenhouse effect on Earth (not includingclouds): carbon dioxide, which causes between 9-26%; and ozone, whichcausesbetween 3-7%(note that it is not really possible to assert that such-and-such a gas causes a certain percentage of the GHE, because the influences of the various gases are not additive .The higher ends of the ranges quoted are for the gas alone ;the lower end ,for the gas counting overlaps).Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrousoxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases.Very powerful greenhouse gases that are not naturally occurring include hydrofluorocarbons(HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are generated in avariety of industrial processes.Each greenhouse gas differs in its ability to absorb heat in the atmosphere. HFCs and PFCsare the most heat-absorbent.2. Individual workGet Ss to answer these questions individually. Then let them discuss the answers.(1) Who wrote the magazine article? What is the name of the magazine?(2) What are the names of the three scientists mentioned in the article?(3) What do they think about global warming? Do they agree with one another?(4) What are the two graphs about?(5) What is the main topic of the article?Step 3. Reading1. SkimmingPurpose: To get a brief understanding of the text.Read through the text, preferably the first and the last sentences of each paragraph and write the key sentence of each paragraph.Key sentences of each paragraph:(1) A debate over whether it is human activity that has caused the global warming or whether it is just a naturalphenomenon.(2) Many scientists believe people have caused the increase in the earth’s temperature.(3) The increased extra amount of carbon dioxide traps more heat energy causing the global temperature to go up.(4) The levels of carbon dioxide have increased greatly over the last 100 to 150 years.(5) There are some different attitudes towards the causes of this increase in carbon dioxide.(6) Over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius but it could be asmuch as 5 degrees Celsius.(7) An increase of five degrees would be a catastrophe.(8) Future warming would cause the sea level to rise by several meters.(9) Some predict any warming will be mild with few bad environmental consequences.(10) More carbon dioxide is a positive thing.(11) No one knows what the effects of global warming will be.2. ScanningPurpose: To get Ss to have some details in the text.Read the article carefully. Are these statements true or false? Write a T for each true sentence and an F for each false sentence.(1) The temperature last century didn’t increase much. ( )(2) Everyone believes that global warming is caused by the activities of humans. ( )(3) Janice Foster believes that burning fossil fuels causes global warming. ( )(4) Natural gas is a greenhouse gas. ( )(5) Carbon dioxide is a byproduct of burning fossil fuels. ( )(6) People accept Charles Keeling ’s data because he took accurate measurements. ( )(7) Flooding could be one of the effects of future global warming. ( )(8) George Hambley believes scientists are just guessing about the effects of global warming.( )(9) Geroge Hambley is worried about the effects of carbon dioxide on plant growth. ( )(10) It is clear what the effects of global warming will be.Suggested Answers:(1) F (2) F (3) T (4) F (5) T (6) T (7) T (8) T (9) F (10) F3.
