Task 2:What's your answer? Two speakers hold a negative attitude toward the world climate conference. Task 3:Let's group work!

Developed countries should bear more responsibilities.

First, they caused most of the world pollution in their industrialization process.

Second, they are already economically advanced, with more funds to deal with pollution problems.

On the other hand, developing countries caused less pollution in the past, and now they need rapid development.

Therefore, an international agreement the Kyoto Protocol in 1997 stipulated common but differentiated responsibilities for developed and developing nations, which means that both should be responsible for environmental protection and cut carbon dioxide emissions, but the former must take more responsibility.

Recently, however, some wealthy countries have insisted that developing countries like China should shoulder more responsibilities. VI. Further Listening and Speaking Listening Task:

Li:Hi, Professor Wang.

I'm Li Lin, a correspondent for the university newspaper.

The staff and students here are getting more and more interested in the relationship between the environment and economic development. What do you think is the most serious environmental problem at present? What measures should we adopt to improve the environment and develop the economy at the same time?

Wang: There are many environmental problems: air pollution, water pollution, desertification, overfishing, destruction of natural habitats, acid rain, overconsumption of wild animals and plants, etc. But lying at the center of all those problems, as I see it, is the contradiction between economic growth and the environment.

Since the United Nations Earth Summit in 1992, growing number of people and governments have adopted the new idea of \This means today's economic growth should not wipe out the resources and options for future generations. Planning and development should ensure not only economic growth, but also social advancement and environmental health. In other words, some economic behavior must be restricted or controlled. Instilling principles of sustainable development into government planning, resource management and economic policy is the most important step China can take to solve its environmental problems.

China has already taken some remarkable steps to reduce damage to the

environment. For instance, following the huge floods of 1998, the government banned logging in the upper reaches of the Yangtze River in order to protect forests and reduce the risk of floods.

Still, the basic contradiction between the environment and development persists. Much work is to be done before we can achieve the aim of a balance between economic growth and the environment. Keys:

Task 2: Thick cloud of pollution covering southern Asia Script

A United Nations study says a thick cloud of pollution covering southern Asia threatens the lives of millions of people. Scientists say the pollution could increase lung disease and cause early death. The cloud is also damaging

agriculture and affecting rainfall levels. It has affected many countries in southern Asia. The pollution cloud is three kilometers high. Scientists say it can move halfway around the world in a week.

The cloud is the result of forest fires, the burning of agricultural waste, and huge increases in the burning of fuels by vehicles, industries, and power stations.

Pollution from millions of bad cooking stoves has made the problem worse. Many poor people burn fuels like wood and animal waste in such stoves. Scientists say the cloud of pollution appears to cool the land and oceans by blocking sunlight.

They say it reduces the amount of sunlight reaching the Earth's surface by as much as 15 percent.

At the same time, heat inside the cloud warms the lower parts of the atmosphere.

Harmful chemicals from the cloud are mixing with rainfall.

This acid rain damages crops and trees and threatens public health. Scientists are concerned that the pollution will intensify during the next 30 years as the population of Asia increases to an estimated 5,000 million people.
