Find out the attitude of James Smith 2. Why? Detailed reading Paragraph 3 SMITH: It's been awful, really. When I first moved here, the air was fresh, the grass green and the water clear. Then heavy industry factories moved in, and things became entirely different. I don't enjoy outdoor activities any more. The river is dirty and smelly. The smog in the air has coloured the sky a smoky grey; it's also given me a cough that I can't get rid of. For health and safety reasons alone, heavy industry has to go. Attitude L14 For health and safety reasons alone, heavy industry has to go. L12-13 The river is dirty and smelly. The smog in the air has coloured the sky a smoky grey; it's also given him a cough that he can't get rid of. Reason Read paragraph 5 Find out the attitude of many businessmen like Vincent Brown Detailed reading BROWN: Well, I'm sorry you feel that way, Mr Smith. People tend to connect factories with pictures of clouds of dirty smoke and irresponsible businessmen eager to make huge profits. In defence of the factories, however, I'd like to point out that we also try to control the amount of pollution we produce. I think I speak for all factory managers when I say we're deeply concerned about the environment. We've been taking various measures, including the use of new technologies, to reduce pollution in the production process, even though these measures raise our production costs. I'd also like to draw your attention to the economic benefits factories have brought to Norgate. We've created many jobs for local residents and helped the city's economy grow. Paragraph 5 Points of view Vincent Brown (1) Factory managers care deeply about the environment and the community. L22 (2) Factories have taken various measures to reduce pollution, even though these measures raise their production costs. L23 (3) Factories have helped Norgate’s economy and created job opportunities for local residents. L26 Read paragraph 7 What have the committee done to protect the environment in Norgate? Detailed reading ARCHER: Well, our committee has a major role to play in maintaining air and water quality. We have to achieve a balance between environmental protection and economic development. We've made environmental policies for businesses to observe, like strict clean-up requirements. We also work hand in hand with other branches of government to ensure that development strategies are followed in an environmentally friendly way. However, fighting pollution isn't just a task for factories and the government. It has to be a community-wide effort, and everyone can help by following the golden rule: reduce, reuse and recycle. For example, you can save energy by taking the bus or the subway, or using the bike-sharing system. Paragraph 7 1. What measures can we take to improve the environment? 2. Do you think things will change significantly in the future? Work in groups and describe what the world will be like 20 years from now.

For our senior high school students, ... You can answer the first Q from many perspectives... Sample answer: I predict that the world will be much cleaner and greener in 20 years. First, cars running on traditional fuels will be replaced by those powered by new energies, such as electricity or solar energy. As a result, the effect of greenhouse gases on the climate will be significantly reduced. Second, almost all reading and writing will be done on computer and phone screens, so people will cut down fewer trees and use less paper. Third, new technologies will be invented to make sure that our daily activities do not have a negative impact on the environment. 1. What measures can we take to improve the environment? 2.
