课件网) Part 1 : Reading and Thinking Discuss Climate change Unit 3 ENVIRONMENTAL PROTECTION 01 02 03 By reading, explain causes and negative effects of global warming. By teamwork, present how to solve the problem of global warming in groups. Be aware of the importance of cutting greenhouse gases and take effective action to do it. By the end of the class, you will be able to Learning Aims What do you know about global warming The effects are destructive as follows: The sea level to rise. Severe storms, droughts, famines, the spread of diseases, and destruction of species. Wide animals died because of starvation. Forest fire occurs frequently because of the extreme hot weather. Lead in What is the graph about What information can you get from it The graph is about the change of global Surface temperature. It shows us that the global temperature is rising steadily and continuously. 2. What happened in the picture Do you know what caused it A polar bear was dead and it is “skin and bones.” The ice is melting on the mountain. Global warming causes the melting of iceberg and some polar bears Suffer from the lack of food. Before you read, look at the graph and the picture below and discuss these questions in groups. 2. What is the graph about What information can you get from it 1 Pre-reading temperature anomaly 温度距平值是某一系列数值中的某一个数值与平均值的差，分正距平和负距平。平均气温距平就是一系列平均气温（日平均气温、月平均气温等）与总平均气温的差值。平均气温距平增高就是说明这个差值增大了，相应时间段内的温度出现了异常。 Earth is getting warmer and warmer. 3. What happened to the polar bear Pre-reading A:The polar bear appeared to have starved to death because it could not find enough to eat. Before you read, look at the graph and the picture below and discuss these questions in groups. 1 4.Why the author write about it Pre-reading A: Because it could show one of effects of rising temperatures due to climate change. Before you read, look at the graph and the picture below and discuss these questions in groups. 1 Read & Think: paragraphs and their main idea Pre-reading ？ Earth is getting warmer and warmer & evidence. Para.1 The evidence (alarming cases) of climate change Para.2 The cause of rising temperature Para.3 The effect of rising temperature Para.4 Solutions to reducing greenhouse gas emission Para.5 Read & Think: The structure and text type Pre-reading ？ evidence Para.1 evidence Para.2 cause Para.3 effect Para.4 solutions Para.5 phenomena Exposition writing Read the text and answer the questions: 1.What is the evidence of global warming 2.Why is the “natural ”greenhouse effect important and necessary 3.What are the consequence of high greenhouse gas emissions 4.Why did the author mention the climate scientists’ warning 5.What is the author’s purpose of writing the text Read the text and answer the questions: What is the evidence of global warming Warming ocean and atmospher ... ...
