Question 1

M: I'll admit it: I'm confused about the state of the world and the environment. I read

that 38 top scientists meeting in Denmark said we should forget about global warming. W: Yes, they said global warming is important, but there are other problems we should

solve like AIDS, hunger, and Malaria. "First things first" is their theme. Q: What do some of the top scientists think about global warming? Question 2

M: It's suicide! We're killing ourselves with acid rain. Smoke from burnt coal mixes with

sunlight to create poisonous sulfuric acid that destroys plants, animals and people like us. W: Hold on! What you've said is true, but governments everywhere are punishing polluters and encouraging alternate energy sources like solar power and wind power. Things are looking up. Q: What is the woman's point of view? Question 3

W: Water pollution in my home town is very serious. I think it's high time that the

government take some measures to tackle the problem before it's too late. M: I think I'm gonna make your eyes green with envy if I tell you that the water in my

home town is well conserved. Q: What can we learn from the dialog?

Question 4

W:John, are you interested in joining in our club to raise money for the protection of wild birds in the States?

M:Why not? I learnt from an article the other day that the wildlife in our country is diminishing. I'll certainly do my part. It's really sad if we can only see wild birds in zoos.

Q:What is the man going to do?

Question 5

W:Mark, did you hear about "black pollution"? I know that "white pollution" refers to plastic pollution. Is "black pollution" related to coal or air exhausted by factories?

M:No, honey. It's the pollution by the waste rubber. It's a serious problem in our country.

Q:What causes "black pollution"?

Every day, the average person breathes in about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air.

Air pollution includes all pollutants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time.

The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air.

Air pollution has been a problem throughout history. Even in Ancient Rome people complained about smoke put into the atmosphere.

The effects of air pollution are diverse and numerous. Air pollution can have serious consequences for the health of human beings, and severely affects the natural ecosystem.

Because it is located in the atmosphere, air pollution is able to travel

easily. As a result, air pollution is a global problem and has been the

subject of global cooperation and conflict.

Some areas now suffer more than others from air pollution. Cities with large numbers of automobiles or those that use great quantities of coal often suffer most severely from air pollution problems.

The panda is found only in the western mountains of China. It is one of the most popular animals in the world. Although it is protected by the Chinese government by strict laws, it is still in serious danger of extinction. Experts guess that there are altogether fewer than 1,000 giant pandas left in China. The pandas live in bamboo forests in the high mountains. Their numbers fell dramatically earlier this century when large areas of bamboo forest were cut down and turned over to agriculture.

To deal with the crisis, experts suggested that special reserves be set up in the remaining forest to protect the pandas.

Also, pandas were taken into zoos to begin a breeding program and the pandas bred there could one day be returned to the wild. Since the panda is a national symbol in China, the program received a lot of attention. However, the panda is a very solitary creature, and the number of pandas in the wild continues to drop. For years, zoos have spent millions of dollars to place pandas together in breeding pairs. Almost all of these actions have ended in failure. As a result, experts predict that pandas will be extinct within 40 to 100 years unless drastic measures are taken.

Because of the strangely solitary nature of the giant panda, the debate about the use of cloning in conservation has emerged in China.

Today mankind faces the loss of one endangered species after another through the destruction of the environment. People cannot afford to lose the panda,

which is found nowhere outside China.
