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 "__".

How could we possibly think that keeping animals in cages in unnatural environments －mostly for entertainment purposes － is fair and respectful?
Zoo officials say they are concerned about animals. However, most zoos remain “collections” of interesting “things” rather than protective habitats. Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.
Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals’ natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range. The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs.
The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusually and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
Furthermore, most animals in zoos are not endangered．Captive breeding(圈养繁殖) of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild．Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven’t we seen enough competitions to name baby animals?
Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats.How would the author describe the animals’ life in zoos?
| A．Dangerous. | B．Unhappy. |
| C．Natural. | D．Easy. |
In the state of zoochosis, animals _________.
| A．remain in cages |
| B．behave strangely |
| C．attack other animals |
| D．enjoy moving around |
What does the author try to argue in the passage?
| A．Zoos are not worth the public support. |
| B．Zoos fail in their attempt to save animals. |
| C．Zoos should treat animals as human beings. |
| D．Zoos use animals as a means of entertainment. |
The author tries to persuade readers to accept his argument mainly by _________.
| A．pointing out the faults in what zoos do |
| B．using evidence he has collected at zoos |
| C．questioning the way animals are protected |
| D．discussing the advantages of natural habitats |

“Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. “There is certainly a lot of energy in waves,” he said. Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. “The wind starts out by making little ripples(涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.” When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine（涡轮机）. The turbine can then power an electrical generator to produce electricity.
“The resource is huge,” said Janet Swain of the World Watch Institute. “We will never run out of wave power.” Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three quarters of the Earth’s surface—that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic. Traditional sources of energy like oil and gas may someday run out. “Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world,” Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!The writer uses the two questions at the beginning of the passage to .

A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon the beautiful castle where the wise man lived.
On entering the main room of the castle, the boy was quite surprised: tradesmen coming and going, people chatting in the corners, and a small orchestra playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn.
The wise man listened carefully to the boy’s explanation of why he had come, but told him that he didn’t have time just then to explain the secret of happiness. He suggested that the boy look around the palace and return in two hours.
“Meanwhile, I want to ask you to do something,” said the wise man, handing the boy a teaspoon that held two drops of oil. “As you wander around, carry this spoon with you without allowing the oil to spill.”
The boy began to walk up and down stairs of the palace, keeping his eyes fixed on the spoon. After two hours, he returned to the wise man.
“Well,” asked the wise man, “Did you see the Persian tapestries（挂毯）in the hall? Did you see the garden that took the master gardener ten years to create?” The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil.
“Then go back and observe the wonders of my world,” said the wise man. The boy picked up the spoon and returned to his exploration of the palace. This time he observed all of the works of art on the ceilings and the walls. When he returned, he described in detail everything he had seen.
“But where are the drops of oil?” asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone.
“Well, there is only one piece of advice I can give you,” said the wise man. “The secret of happiness is to see all the wonders of the world, and never to forget the drops of oil on the spoon.”When the boy arrived at the castle, he .
| A．received a warm welcome from the wise man |
| B．had already missed his chance to talk to the wise man |
| C．was shown around the palace by the local people |
| D．didn’t expect to see so many people around |
The wise man gave the boy two tasks in order to .
| A．show him how to observe the wonders in the world |
| B．teach him the secret of happiness |
| C．make him learn from his mistakes |
| D．let the boy enjoy his palace and garden |

| A．the beauty of one’s nature |
| B．the fortune a person possesses |
| C．the responsibilities one has to take on |
| D．the great opportunities in life |
