The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3°C on average, with melting ice contributing to a global sea level increase of up to 1.4 meters.

In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual.

But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3°C and a reduction in sea ice by around a third.

The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades.

Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected —Antarctica may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 meters."

Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 meters higher by the end of the century.

The underlined word "paradoxically" (in Paragraph 2) most probably means "__".

A. rapidly B. approximately C. contradictorily D. apparently

love charity(慈善) shops and so do lots of other people in Britain because you find quite a few of them on every high street. The charity shop is a British institution, selling everything from clothes to electric goods, all at very good prices. You can get things you won’t find in the shops anymore. The thing I like best about them is that your money is going to a good cause and not into the pockets of profit-driven companies, and you are not damaging the planet, but finding a new home for unwanted goods.

The first charity shop was opened in 1947 by Oxfam. The famous charity’s appeal to aid postwar Greece had been so successful it had been flooded with donations(捐赠物). They decided to set up a shop to sell some of these donations to raise money for that appeal. Now there are over 7,000 charity shops in the UK. My favourite charity shop in my hometown is the Red Cross shop, where I always find children’s books, all 10 or 20 pence each.

Most of the people working in the charity shops are volunteers, although there is often a manager who gets paid. Over 90% of the goods in the charity shops are donated by the public. Every morning you see bags of unwanted items outside the front of shops, although they don’t encourage this, rather ask people to bring things in when the shop is open.

The shops have very low running costs: all profits go to charity work. Charity shops raise more than ￡110 million a year, funding（资助）medical research, overseas aid, supporting sick and poor children, homeless and disabled people, and much more. What better place to spend your money? You get something special for a very good price and a good moral sense. You provide funds to a good cause and tread lightly on the environment. （08天津卷）

Global warming is causing more than 300,000 deaths and about $125 billion in economic losses each year, according to a report by the Global Humanitarian Forum, an organization led by Kofi Annan, the former United Nations secretary general.

The report, to be released Friday, analyzed data and existing studies of health, disaster, population and economic trends. It found that human-influenced climate change was raising the global death rates from illnesses including malnutrition and heat-related health problems.

But even before its release, the report drew criticism from some experts on climate and risk, who questioned its methods and conclusions. Along with the deaths, the report said that the lives of 325 million people, primarily in poor countries,were being seriously affected by climate change. It projected that the number would double by 2030.

Roger Pielke Jr., a politicalscientist at the University of Colorado, Boulder, who studies disaster trends, said the Forum’s report was “a methodological embarrassment” because there was no way to distinguish deaths or economic losses related to human-driven global warming amid（在...中间） the much larger losses resulting from the growth in populations and economic development in vulnerable(易受伤害的) regions. Dr. Pielke said that “climate change is an important problem requiring our utmost attention.” But the report, he said, “will harm the cause for action on both climate change and disasters because it is so deeply flawed(有瑕疵的).”

However, Soren Andreasen, a social scientist at Dalberg Global Development Partners who supervised the writing of the report, defended it, saying that it was clear that the numbers were rough estimates. He said the report was aimed at world leaders, who will meet in Copenhagen in December to negotiate a new international climate treaty.

In a press release describing the report, Mr. Annan stressed the need for the negotiations to focus on increasing the flow of money from rich to poor regions to help reduce their vulnerability to climate hazards while still controling the emissions of the heat-trapping gases. More than 90% of the human and economic losses from climate change are occurring in poor countries, according to the report.

1.What is the finding of the Global Humanitarian Forum?

A. Rates of death from illnesses have risen due to global warming.

B. Global temperatures affect the rate of economic development.

C. Malnutrition has caused serious health problems in poor countries.

D. Economic trends have to do withpopulation and natural disasters.

2. What do we learn about the Forum’s report from the passage?

A. It caused a big stir in developing countries.

B. It was warmly received by environmentalists.

C. It caused a lot of interest in the scientific circles.

D. It was challenged by some climate and risk experts.

3. What is Soren Andreasen’s view of the report?

A. Its conclusions are based on carefully collected data.

B. It is vulnerable to criticism if the statistics are closely examined.

C. It will give rise to heated discussions at the Copenhagen conference.

D. Its rough estimates are meant to draw the attention of world leaders.

4.What does Kofi Annan say should be the focus of the Copenhagen conference?

A. How human and economic losses from climate change can be reduced.

B. How rich countries can better help poor regions reduce climate hazards.

C. How emissions of heat-trapping gases can be reduced on a global scale.

D. How rich and poor regionscan share responsibility in curbing global warming.

Kodak’s decision to file for bankruptcy (破产) protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but ultimately failed to adapt to the digital revolution.

Although many attribute Kodak’s downfall to “complacency (自满) ,” that explanation doesn’t acknowledge the lengths to which the company went to reinvent itself. Decades ago, Kodak predicted that digital photography would overtake film (胶片) — and in fact, Kodak invented the first digital camera in 1975 — but in a fateful decision, the company chose to shelf its new discovery to focus on its traditional film business.

“It wasn’t that Kodak was blind to the future”, said Rebecca Henderson, a professor at Harvard Business School, but rather that it failed to execute on a strategy to confront it. By the time the company realized its mistake, it was too late.

Kodak is an example of a firm that was very much aware that they had to adapt, and spent a lot of money trying to do so, but ultimately failed. Large companies have a difficult time switching into new markets because there is a temptation to put existing assets (资产) into the new businesses.

Although Kodak predicted the unavoidable rise of digital photography, its corporate (企业的) culture was too rooted in the successes of the past for it to make the clean break necessary to fully embrace the future. They were a company stuck in time. Their history was so important to them. Now their history has become a liability.

Kodak’s downfall over the last several decades was dramatic. In 1976, the company commanded 90% of the market for photographic film and 85% of the market for cameras. But the 1980s brought new competition from Japanese film company Fuji Photo, which undermined Kodak by offering lower prices for film and photo supplies. Kodak’s decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major miscalculation. The bid went instead to Fuji, which exploited its sponsorship to win a permanent foothold in the marketplace.

1.What do we learn about Kodak?

A. It went bankrupt all of a sudden.

B. It is approaching its downfall.

C. It initiated the digital revolution in the film industry.

D. It is playing a dominant role in the film market.

2.Why does the author mention Kodak’s invention of the first digital camera?

A. To show its early attempt to reinvent itself.

B. To show its effort to overcome complacency.

C. To show its quick adaptation to the digital revolution.

D. To show its will to compete with Japan’s Fuji photo.

3.Why do large companies have difficulty switching to new markets?

A. They find it costly to give up their existing assets.

B. They tend to be slow in confronting new challenges.

C. They are unwilling to invest in new technology.

D. They are deeply stuck in their glorious past.

4.What does the author say Kodak’s history has become?

A. A burden. B. A mirror. C. A joke. D. A challenge.
