The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator ,The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity -- roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meat tickets worth $36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel. The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard, hotel spokeswoman, said, "Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme," Copenhagen has a long-standing cycling tradition and 36% of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen.dk. US environmental website treehugger.com recently voted Copenhagen the world's best city for cyclists. "Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile ." If successful, the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement. What is the main purpose of the free meal programme? A) To promote the hotel's green concept. B) To make the city known to the world. C) To attract people to the hotel restaurant. D) To get guests to stay longer at the hotel.

(Question)
A month after Hurricane Katrina,I returned home in New Orleans.There lay my house,reduced to waist-high rains,smelly and dirty.Before the trip,I'd had my car fixed.When the office employee of the garage was writing up the bill.she noticed my Louisiana license plate."You from New Orleans?"she asked.I said l was, "No charge."She said,and firmly shook her head when I reached for my wallet.The next day I went for a haircut,and the same thing happened. As my wife was studying in Florid,we decided to move there and tried to find a rental house that we could afford while also paying off a mortgage on our ruined house.We looked at many places,but none was satisfactory.We'd begun to accept that we'd have to live in extremely reduced circumstances for a while,when I got a very curious e-mail from a James Kennedy in California.He'd read some pieces I'd written about our sufferings forState,an online magazine and wanted to give us("noconditions attached")a new house across the lake from New Orleans.It sounded too good to be true,but I replied,thanking him for his exceptional generosity,that we had no plans to go back.Then a poet of the University of Florida offered to let his house to me while he went to England on his one-year-paid leave.The rent was rather reasonable.Imentioned the poet's offer to James Kennedy,and the next day he sent a check covering our entire rent for eight months. Throughout this painful experience,the kindness of strangers backs my faith in humanity.It's almostworthlosing you worldly possessions to be reminded that people really want to be kind when given a channel. How is the passage developed? A) By showing contrasting facts. B) By making classification C) By giving examples. D) By analyzing causes and effects.

Ques:Researchers at Sweden's KTH Royal Institute of Technology say they have found further proof that the wolf ancestors of today's dogs can be from southern East Asia -- findings that are contrary to theories placing the birth place in the Middle East. Dr Peter Savolainen, KTH researcher in evolutionary genetics, says a new study released Nov. 23 confirms that an Asian region south of the Yangtze River was the principal and probably the only region where wolves were domesticated by humans. Research data show clearly that dogs are descended from wolves, but there's never been scientific agreement on where in the world the domestication process began. "Our analysis of Y-chromosomal DNA now confirms that wolves were first domesticated in Asia south of Yangtze River -- we call it the ASY region -- in southern China or Southeast Asia," Savolainen says. The Y data supports previous evidence from mitochondrial DNA. "Taken together, the two studies provide very strong evidence that dogs appeared first in the ASY region," Savolainen says. Archaeological data and a genetic study recently published in Nature suggest that dogs originate from the Middle East. But Savolainen rejects that view. "Because none of these studies included samples from the ASY region, evidence from ASY has been overlooked," he says. Peter Savolainen and PhD student Mattias Oskarsson worked with Chinese colleagues to analyse DNA from male dogs around the world. Their study was published in the scientific journal Heredity. Approximately half of the gene pool was universally shared everywhere in the world, while only the ASY region had the entire range of genetic diversity. "This shows that gene pools in all other regions of the world most probably originate from the ASY region," Savolainen says. "Our results confirm that Asia south of the Yangtze River was the most important -- and probably the only -- region for wolf domestication, and that a large number of wolves were domesticated," says Savolainen. In separate research published recently in Ecology... We can learn from the passage that _ . A) there is a universal agreement on the place of first domestication B) data from ASY may highlight where dogs came from C) Dr. Savolainen's research mainly focuses on the Middle East D) the dog/wolf hybridization makes up most of the dog gene pool
