Unit 2 The Environment 教学案 1Revision: 1. Test some word spelling2. Free talk: Talk about “the environment”Lead-in1. Tell a story: Last term I visited a paper-making mill to investigate what damage it was doing to the local environment. I saw waste water ran into the rivers without being treated. The whole river was polluted. I could not help asking the director of the mill why they had not introduced any purification facilities to treat the waste. I was told that the mill could not afford to invest in any pollution control devices. “After all，” he said， “if people want paper， they have to get used to the waste， too.”2. Question: 1) What do you think about what the director of the paper mill said？ 2) Do you think we can achieve a balance between the economy and the environment？ 3) Some people think its impossible to improve our living standards without damaging the environment.
