Rising temperatures and overfishing in the pristine(未受污染的) waters around the Antarctic could see king penguin populations pushed to the brink of extinction by the end of the century, according to a new study. The study's report states that as global warming transforms the environment in the world's last great wilderness, 70 percent of king penguins could either disappear or be forced to find new breeding grounds.
Co-author Celine Le Bohec, from the University of Strasbourg in France, warned: "If there're no actions aimed at halting or controlling global warming, and the pace of the current human-induced changes such as climate change and overfishing stays the same, the species may soon disappear." The findings come amid growing concern over the future of the Antarctic. Earlier this month a separate study found that a combination of climate change and industrial fishing is threatening the krill(磷虾) population in Antarctic waters, with a potentially disastrous impact on whales, seals and penguins. But today's report is the starkest warming yet of the potentially devastating impact of climate change and human exploitation on the Antarctic's delicate ecosystems.
Le Bohec said: "Unless current greenhouse gas emissions drop, 70 percent of king penguins -- 1.1 million breeding pairs -- will be forced to relocate their breeding grounds, or face extinction by 2100." King penguins are the second-largest type of penguin and only breed on specific isolated islands in the Southern Ocean where there is no ice cover and easy access to the sea. As the ocean warms, a body of water called the Antarctic Polar Front -- an upward movement of nutrient-rich sea that supports a huge abundance of marine life -- is being pushed further south. This means that king penguins, which feed on fish and kill in this body of water, have to travel further to their feeding grounds, leaving their hungry chicks for longer. And as the distance between their breeding, grounds and their fool prows, entire colonies could be wiped out.
Le Bohec said: "The plight of the king penguin should serve as a warming about the future of the entire marine environment in the Antarctic. Penguins, like other seabirds and marine mammals, occupy higher levels in the food chain and they are what we call bio-indicators of their ecosystems." Penguins are sensitive indicators of changes in marine ecosystems. As such, they are key species for understanding and predicting impacts of global change on Antarctic and sub-Antarctic marine ecosystems. The report found that although some king penguins may be able to relocate to new breeding grounds closer to their retreating food source, suitable new habitats would be scarce. Only a handful of islands in the Southern Ocean are suitable for sustaining large breeding colonies.
51.A) King penguins in the Antarctic will be on the verge of dying out.
52.C) Industrial fishing and climate change could be fatal to certain Antarctic species.
53.D) The majority of them may have to find new breeding grounds in the future.
54.A) Many baby king penguins can't have food in time.
55.D) Only a few of its islands can serve as luge breeding grounds for king penguins.

The fifth largest city in US passed a significant soda tax proposal that will levy (征税)1.5 cents per liquid ounce on distributors.
Philadelphil's new measure was approved by a 13 to 4 city council vote. It sets a new bar for similar initiatives across the country. It is proof that taxes on sugary drinks can win substantial support outside super-liberal areas. Until now, the only city to successfully pass and implement a soda tax was Berkeley, California, in 2014.
The tax will apply to regular and diet sodas, as well as other drinks with adder sugar, such as Gatorade and iced teas. It's expected to raise $410 million over the next five years, most of which will go toward funding a universal pre-kindergarten program for the city.
While the city council vote was met with applause inside the council room, opponents to the measure, including soda lobbyists, made sharp criticisms and a promise to challenge the tax in court.
"The tax passed today unfairly singles out beverages — including low —and no-calorie choices," said Lauren Kane, spokeswoman for the American Beverage Association. "But most importantly, it is against the law. So we will side with the majority of the people of Philadelphia who oppose this tax and take legal action to stop it."
An industry-backed anti-tax campaign has spent at least $4 million on advertisements. The ads criticized the measure, characterizing it as a "grocery tax".
Public health groups applauded the approved tax as step toward fixing certain lasting health issues that plague Americans. "The move to recapture a small part of the profits from an industry that pushed a product that contributes to diabetes, obesity and heart disease in poorer communities in order to reinvest in those communities will sure be inspirational to many other places," said Jim Krieger, executive director of Healthy Food America. "indeed, we are already hearing from some of them. It's not 'just Berkeley' anymore."
Similar measures in California's Albany, Oakland, San Francisco and Colorado's Boulder are becoming hot-button issues. Health advocacy groups have hinted that even more might be coming.

A) Getting around a city is one thing -- and then there's the matter of getting from one city to another. One vision of the perfect city of the future: a place that offers easy access to air travel.In 2011, a University of North Carolina business professor named John Kasarda published a book called Aerotropolis: The Way We'll Live Next. Kasarda says future cities should be built intentionally around or near airports. The idea, as he has put it, is to offer businesses "rapid, long-distance connectivity on a massive scale."
B) "The 18th century really was a waterborne century, the 19th century a rail century, the 20th century a highway, car, truck century -- and the 21st century will increasingly be an aviation century, as the globe becomes increasingly connected by air," Kasarda says.Songdo, a city built from scratch in South Korea, is one of Kasarda's prime examples. It has existed for just a few years."From the get-go, it was designed on the basis of connectivity and competitiveness," says Kasada. "The government built the bridge directly from the airport to the Songdo International Business District. And the surface infrastructure was built in tandem with the new airport."
C) Songdo is a stone's throw from South Korea's Incheon Airport, its main international hub. But it takes a lot more than a nearby airport to be a city of the future. Just building a place as an "international business district" doesn't mean it will become one. Park Yeon Soo conceived this city of the future back in 1986. He considers Songdo his baby. "I am a visionary," he says.Thirty years after he imagined the city, Park's baby is close to 70 percent built, with 36,000 people living in the business district and 90,000 residents in greater Songdo. It's about an hour outside Seoul, built on reclaimed tidal flats along the Yellow Sea. There's a Coast Guard building and a tall trade tower, as well as a park, golf course and university.
D) Chances are you've actually seen this place. Songdo appears in the most famous music video ever to come out of South Korea."Gangnam Style" refers to the fashionable Gangnam district in Seoul. But some of the video was filmed in Songdo."I don't know if you remember, there was a scene in a subway station. That was not Gangnam. That was actually Songdo," says Jung Won Son, a professor of urban development at London's Bartlett School of Planning. "Part of the reason to shoot there is that it's new and nice."
E) The city was supposed to be a hub for global companies, with employees from all over the world. But that's not how it has turned out.Songdo's reputation is as a futuristic ghost town. But the reality is more complicated.A bridge with big, light-blue loops leads into the business district. In the center of the main road, there's a long line of flags of the world. On the corner, there's a Starbucks and a 7-Eleven -- all of the international brands that you see all over the world nowadays.
F) The city is not empty. There are mothers pushing strollers, old women with walkers -- even in the middle of the day, when it's 90 degrees out. Byun Young-Jin chairs the Songdo real estate association and started selling property here when the first phase of the city opened in 2005. He says demand has boomed in the past couple of years.Most of his clients are Korean. In fact, the developer says, 99 percent of the homes here are sold to Koreans. Young families move here because the schools are great.And that's the problem: Songdo has become a popular Korean city -- more popular as a residential area than a business one. It's not yet the futuristic international business hub that planners imagined. "It's a great place to live. And it's becoming a great place to work," says Scott Summers, the vice president of Gale International, the developer of the city. The floor-to-ceiling windows of his company's offices overlook Songdo Central Park, with a canal full of kayaks and paddle boats. Shimmering glass towers line the canal’s edge.
G) "What's happened is, because we focused on creating that quality of life first, which enabled the residents to live here, what has probably missed the mark is for companies to locate here," he says. "There needs to be strong economic incentives."The city is still unfinished, and it feels a bit like a theme park. It doesn't feel all that futuristic. There's a high-tech underground trash disposal system. Buildings are environmentally friendly. Everybody's television set is connected to a system that streams personalized language or exercise classes.
H) But Star Trek this is not. And to some of the residents, Songdo feels hollow."I'm, like, in prison for weekdays. That's what we call it in the workplace," says a woman in her 20s. She doesn't want to use her name for fear of being fired from her job. She goes back to Seoul every weekend. "I say I'm prison-breaking on Friday nights."But she has to make the prison break in her own car. There's no high-speed train connecting Songdo to Seoul, just over 20 miles away.
I) The man who first imagined Songdo feels frustrated, too. Park says he built South Korea a luxury vehicle, "like Mercedes or BMW. It's a good car now. But we're waiting for a good driver to accelerate."But there are lots of other good cars out there, too. The world is dotted with futuristic, high-tech cities trying to attract the biggest international companies.
J) Songdo's backers contend that it's still early, and business space is filling up -- about 70 percent of finished offices are now occupied.Brent Ryan, who teaches urban design at MIT, says Songdo proves a universal principle. "There have been a lot of utopian cities in history. And the reason we don't know about a lot of them is that a lot of them have vanished entirely."In other words, when it comes to cities -- or anything else -- it is hard to predict the future.
36. Songdo's popularity lies more in its quality of life than its business attraction.
37. The man who conceived Songdo feels disappointed because it has fallen short of his expectations.
38. A scene in a popular South Korean music video was shot in Songdo.
39. Songdo still lacks the financial stimulus for businesses to set up shop there.
40. Airplanes will increasingly become the chief means of transportation, according to a professor.
41. Songdo has ended up diferent from the city it was supposed to be.
42. Some of the people who work in Songdo complain about boredom in the workplace.
43. A business professor says that a future city should have easy access to international transportation.
44. According to an urban design professor, it is difficult for city designers to foresce what will happen in the future.
45. Park Yeon Soo, who envisioned Songdo, feels a parental connction with the city.
