With area of around 6 million square kilometres , the Amazon rainforest is more than half thesize of China. The Amazon River, from the rainforest gets its name, is closeto 6,400 kilometres in （long）- （rough) 100 kilometres longer than the Yangtze River. On its journey from the mountains to the ocean, the river supports many different ecosystems. They give this area the

Of the 390,000 plant species （know）to us, more than 40,000 can be found in the Amazon. This tall and ancient brazil nut tree produces nuts we can eat; thesewater lilies are big enough to lie down on. The forest's different levels support anunbelievable (vary）of wildlife. At the bottom, there is a system of roots beneaththe ground. Above that is the mass of leaf litter on the dark forest floor. The nextlevel is made up of shorter plants with large leaves. Then there are the (tower) ancient hardwoods, and finally the tops of the tallest trees many metres above theground. Each level of the forest forms its own little world, home different kindsof （live）things.

More than 1,300 species of birds and over 400 species of mammals hide among the jungle’s plant life. This jaguar is one example. It has a yellowish-brown coat with black spots. a significant number of jaguars survive here, they are only one element of this forest’s food chain. They feed at least 87 species, including frogs. These frogs, in turn, feed on insects eat leaves and fruit. When a jaguar dies, a tiny army of microorganisms helps break its body and return the nutrients to the ear

The Amazon rainforest breathes life the planet by fixing carbon and
（produce) over 20 per cent of all the Earth's oxygen. Thus, it is often known as the “lungs ofthe planet". Moreover, the Amazon rainforest is a treasure house of species can be used for food or medicine. Yet there is one major danger to these irreplaceableplants and animals: us. Over the past 50 years, about 17 per cent of the rainforest （appear） due to human activities such as agriculture and cattie farming. Asthe impact of human activities continues （grow）and the list of species in danger of (extinct) becomes longer, we are left with a question: can we afford (damage) the “lungs of the planet”？

HOST: Good evening and welcome to News that Matters. Our topic today is pollution in Norgate. (join) us in the studio tonight (be) James Smith, a local resident; Vincent Brown, senior manager of a local factory; and Julie Archer, chief of the Norgate Environmental Protection Committee. Welcome.
Norgate’s rapid development has had significant environmental costs. Mr Smith, you’ve lived in this city for over 20 years. How would you describe the effects of pollution over that time

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 (entire) 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.
HOST: Mr Smith protested heavy industry. Mr Brown, would you like to respond

BROWN: Well, I’m sorry you feel that way, Mr Smith. People tend
(connect) factories with pictures of clouds of dirty smoke and
（responsible）businessmen eager to make huge （profit). In （defend）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 (concern)about the environment. We’ve been taking (vary） measures, ( include) the use of new technologies, (reduce) pollution in the production process, even though these measure 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.

HOST: Thank you, Mr Brown. With pollution levels the rise, the Norgate Environmental Protection Committee is searching for ways (fight) the problem. Mrs Archer, what are your thoughts on how to deal with pollution

ARCHER: Well, our committee has a major role (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 (observe), like strict clean-up requirements. We also work hand in hand with other branches of government (ensure) that development strategies are followed in an (environment) friendly way. However, (fight) pollution isn’t just a task for factories and the government.Ithas 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.

HOST: Thank you, Mrs Archer, and thanks again to all of our guests. A former UN official once said, “Saving our planet, lifting people out of (poor), advancing economic growth ... these are one and the same fight.” The fortunes of our environment and our economy are inseparable. It’s our duty (protect) the environment while we aim for economic development. It’s our duty to leave a better, cleaner and (health) planet to our children. It’s our duty to build a human community with a (share) future.
