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℃on average, with melting ice contributing to a global sea level increase of up to 1.4 metres.

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℃ 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 metres."

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 metres higher by the end of the century.

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

65. What do scientists think is the biggest danger facing Antarctica?

A. Rising sea levels.                  B. Warming sea water temperature.

C. Water pollution.                      D. Growing ice sheets.

66. Which of the following is true according to the passage?

One would have to be a fool to overlook the importance of using positive thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little w*w^w..c~o*mchemicals and good feelings which will reinforce the positive thoughts.

For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.

It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.

B. be king in your office

C. pay no attention to what is going on around you
