听力原文： A steadily expanding appetite for coal, fuelled by China' s rapid industrial growth, has led to a dramatic rise in environmental damage from acid rain, the China Daily, an official Chinese newspaper, reported on December 7,1999. The newspaper summarised the findings of a recent study conducted by the Chinese Academy of Sciences (CAS) and the Chinese Academy of Forestry(CAF).

The study' s authors said that after Europe and North America, China is the world' s third largest region to be affected by acid rain, a type of air pollution formed when oxides of sulfur and nitrogen combine with atmospheric moisture. Nearly 50 percent of China' s land area is now affected, a figure the researchers expect will rise.

I had to go to Washington last week for a conference. I arrived at the airport in plenty of time and checked in, but I only had one small case so I decided to take it on the plane as hand luggage. As the flight was not due to board for 45 minutes, I went to a cafe, sat down, and ordered a cup of coffee.

While I was sitting there drinking my coffee and reading my paper, I was vaguely aware of a woman and her child coming to sit at the next table. I did not pay much attention to them, though, and when my flight was called I reached for my case and left. An hour later, the plane was in the air and I decided to look at the conference programme to see what I wanted to attend. Imagine my horror when I opened the case and found that it was full of picture books and children' s toys—and imagine what-the woman must have thought about a case full of men' s clothes and scientific papers!

It is widely accepted that English is the global language of modern times. About three decades ago, French was recognized as the language of diplomacy (外交), and German was considered the language of science and technology. English now dominates(主导) not only as the language of science but also diplomacy, computing, and tourism.

Today, in terms of native speakers, Mandarin Chinese is the world′s largest language. Yet there are people who believe that China will become the most powerful country in the world. Some have even fixed the date as early as the year 2020.

At present, while English is more widely spoken than any other language,there are more people who speak Chinese than English due to the large population in China alone. If China does become a world power, there is no doubt that this language will spread worldwide.

As the controversy over which language will become dominant in the world continues, there are many who feel that the dominance of English is unique and irreversible (不可逆的 ). However, a separate study from David Graddol′s suggests that English′s dominance in the scientific area will continue. There is also an argument that the English language would be changed greatly by 2020 for various reasons. With the possibility of China rising as a world power,Mandarin could definitely challenge the dominance of English as a global language.
