UNIT 3 Reading and thinking 教案 Learning aims : To discuss climate change To learn to identify the style of this text and infer the writer’s purpose To learn to draw a diagram To think about how we can do to deal with climate change Warming up Climate change is a heat topic for the scientists around the world. They all try to find out the truth about these questions: What causes climate change? What are the solutions to stop climate change? View the video. What other consequences may global warming bring about? Before you read, look at the graph and the picture on Page 26 and discuss these questions in groups. 1. What is the graph about?
